[0005] This disclosure relates to the field of fluid connection device technology, and more particularly to a fluid connection component. Background Technology

[0006] With the continuous advancement of technology, various fluid transfer systems have been widely used in daily production and life. Connectors, as a crucial component ensuring the safe and efficient transport of fluids, typically involve the assembly of multiple parts. In existing technologies, fluid connectors are usually assembled using rotary connections, thus requiring a limiting structure between the two mating connectors to achieve a rotational limiting function after connection.

[0007] To achieve the locking function of the limiting structure, most existing connectors employ a multi-hole (three or more holes) structure. This structure, along with the locking rod and push rod, is arranged and mates with the body, and locking steel balls are placed between the connected holes to achieve locking and unlocking functions. This design assembles multiple pins within a limited space to achieve the locking effect. However, to avoid excessive body size and ensure the functionality of multiple holes, the hole diameter is usually set relatively small, resulting in a corresponding reduction in the diameter of each pin within the body, thus affecting the strength of the pins. This insufficient strength structure can easily lead to the breakage or failure of the locking pins in high-pressure fluid transmission environments, causing potential safety hazards, and even leading to fluid leakage and equipment damage. Especially in high-pressure process transmission environments, the pins are prone to breakage, causing connector failure.

[0008] Therefore, it is necessary to address the aforementioned issues in order to change the current situation. Summary of the Invention

Detailed Implementation

[0096] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0097] With the continuous advancement of technology, various fluid transfer systems have been widely used in daily production and life. Connectors, as a crucial component ensuring the safe and efficient transport of fluids, typically involve the assembly of multiple parts. In existing technologies, fluid connectors are usually assembled using rotary connections, thus requiring a limiting structure between the two mating connectors to achieve a rotational limiting function after connection.

[0098] To achieve the locking function of the limiting structure, most existing connectors employ a multi-hole (three or more holes) structure. This structure, along with the locking rod and push rod, is arranged and mates with the body, and locking steel balls are placed between the connected holes to achieve locking and unlocking functions. This design assembles multiple pins within a limited space to achieve the locking effect. However, to avoid excessive body size and ensure the functionality of multiple holes, the hole diameter is usually set relatively small, resulting in a corresponding reduction in the diameter of each pin within the body, thus affecting the strength of the pins. This insufficient strength structure can easily lead to the breakage or failure of the locking pins in high-pressure fluid transmission environments, causing potential safety hazards, and even leading to fluid leakage and equipment damage. Especially in high-pressure process transmission environments, the pins are prone to breakage, causing connector failure.

[0099] To address the aforementioned problems, referring to Figures 1 to 12, this embodiment of the present disclosure provides a fluid connector 10, which has an internal flow channel for conveying fluid. The connector 10 includes a connecting member 100, a limiting component 200, and an operating mechanism 300. The connecting member 100 has an installation cavity 1111 spaced apart from the flow channel. The limiting component 200 is movably accommodated within the installation cavity 1111. The limiting component 200 includes a limiting pin 210, a switching pin 220, and a locking member 230. The locking member 230 is movably connected to the limiting pin 210 and the limiting pin 210; the operating mechanism 300 is drively connected to the limiting pin 210; wherein, the switching pin 220 can move between a first position and a second position. In the first position, the locking member 230 is locked to the limiting pin 210 and the connecting member 100; in the second position, the locking member 230 releases the limiting pin 210 and the connecting member 100, and the operating mechanism 300 can drive the limiting pin 210 to move relative to the connecting member 100.

[0100] In this embodiment, the fluid connector 10 improves the combination of the connecting member 100 and the limiting component 200, effectively solving the problem of insufficient locking pin strength in the prior art, thereby achieving a safer and more reliable connection effect.

[0101] Specifically, in this embodiment, the connecting member 10, by having the limiting pin 210, the switch pin 220, and the locking member 230 of the limiting assembly 200 all disposed within the mounting cavity 1111, allows the switch pin 220 to move between a first position and a second position, thereby enabling the locking member 230 to lock and release the limiting pin 210. This design allows the limiting pin 210 to connect to another set of connecting members 10, thus providing a limiting function for both.

[0102] Compared to existing connectors, the connector 10 in this embodiment does not require additional holes to accommodate the switch pin 220 to achieve the linkage function of the limiting component 200. Due to the optimized number of holes, the connector 10 in this embodiment can increase the diameter of the mounting cavity 1111, thereby increasing the size of the limiting pin 210 and the switch pin 220, improving the overall strength of the limiting component 200, enhancing the working stability of the connector 10 under high pressure conditions, and ensuring the compactness of the overall structure of the connector 10. Furthermore, it should be noted that the connector 10 in this embodiment can be applied to fluids such as liquids and gases, and is not limited to any particular type.

[0103] In one embodiment, as shown in Figures 1, 5 and 12, the connecting member 100 is further provided with a locking groove 1112 spaced apart from the mounting cavity 1111; in the second position, the operating mechanism 300 can drive the limiting pin 210 to be inserted into the locking groove 1112 of another set of connecting members 10.

[0104] This configuration effectively achieves a stable connection between the connectors 10, improving the reliability and durability of the overall structure. Specifically, in this embodiment, from a structural perspective, when the two sets of connectors 10 are docked, their connecting surfaces 1114 are first positioned opposite each other and docked. Subsequently, when the switch pin 220 moves to the second position, the operating mechanism 300 can drive the limiting pin 210 to insert into the locking groove 1112 of the other set of connectors 10, forming an effective physical connection and positioning. This design ensures that, under safe and stable conditions, the limiting pin 210 and the locking groove 1112 can achieve efficient interaction, thereby precisely limiting the mutual rotation between the two sets of connectors 10.

[0105] When it is necessary to separate the two sets of connecting parts 10, the limiting pin 210 can be separated from the locking groove 1112 by adjusting the operating mechanism 300 in the reverse direction. It is worth noting that after the limiting pin 210 moves into place, the locking member 230 can then lock the limiting pin 210 and the connecting member 100, thereby ensuring that the safety and convenience of the system are fully reflected throughout the entire operation.

[0106] In existing connectors, at least three holes are typically provided, with each hole corresponding to a switch locking pin, a limit locking pin, and an unlocking component. The switch locking pin and the limit locking pin are each located within two of the holes. The unlocking component moves between the switch locking pin and the limit locking pin to unlock or release them. When two sets of connectors are connected, the limit locking pin is inserted into the other hole to limit the movement of the two sets of connectors. In this design, because multiple holes need to be provided on the connector, the hole diameter needs to be designed to be as small as possible to avoid the holes occupying too much space on the connector. This results in the switch locking pin and the limit locking pin having excessively small diameters and limited strength.

[0107] In the connector 10 of this embodiment, by integrating the limiting component 200 into the mounting cavity 1111 of the connecting member 100, the connecting member 100 is provided with the mounting cavity 1111 and the locking groove 1112 to realize the locking function of the limiting component 200. In this way, the aperture of the mounting cavity 1111 and the locking groove 1112 can be designed to be larger to improve the strength of the limiting component 200.

[0108] Furthermore, the connecting member 100 is also provided with an abutment portion 1113, which is located within the locking groove 1112. When the two sets of connecting members 10 are mated, the abutment portion 1113 abuts against the switch pin 220 to move the switch pin 220 to the second position. Thus, when the abutment portion 1113 contacts the switch pin 220, it can effectively push the switch pin 220 to move, thereby realizing the unlocking function of the locking member 230 between the limiting pin 210 and the connecting member 100.

[0109] In this embodiment, by configuring the abutment portion 1113 on the connecting member 100, the limiting component 200 can smoothly realize the unlocking function of the switch pin 220 without adding additional driving components, simplifying the overall design. Furthermore, specifically, the abutment portion 1113 can be directly formed into an effective structure on the connecting surface 1114 of the connecting member 100 through machining. In a preferred embodiment, the abutment portion 1113 can be designed as a cylindrical structure, while the locking groove 1112 is a circular hole, and the locking groove 1112 and the abutment portion 1113 are coaxially arranged, thereby ensuring the concentration and effectiveness of force transmission.

[0110] Of course, in some other embodiments, the abutment portion 1113 can be selectively omitted, and an additional unlocking component can be used instead to drive the switch pin 220 to move between the first and second positions. This unlocking component can be in various forms such as a linear actuator or a cylinder. The advantage of using an additional unlocking component in this design is that it allows for flexible adaptation to more complex operating environments, improves the maintainability and modularity of the system, and allows switching between different driving methods to meet specific application requirements.

[0111] In one embodiment, the outer diameter of the switch pin 220 is a, the inner diameter of the locking groove 1112 is b, and the outer diameter of the abutment portion 1113 is c, and the following relationship is satisfied: a>(bc) / 2.

[0112] In this embodiment, by defining the relationship between dimensions a, b, and c, it is ensured that the outer diameter of the switch pin 220 is greater than the gap between the abutment portion 1113 and the locking groove 1112. This arrangement ensures that when the two sets of connecting members 10 are rotating and docking, when the switch pin 220 of one set of connecting members 10 rotates to the position of the locking groove 1112, the switch pin 220 will not enter the gap between the locking groove 1112 and the abutment portion 1113, but can smoothly abut against the abutment portion 1113.

[0113] Specifically, when the condition that the outer diameter a of the switch pin 220 is greater than (bc) / 2 is met, it can effectively prevent the switch pin 220 from getting stuck or accidentally entering during the docking process. This design not only improves the safety and stability of the connector during the docking process, but also enhances the connection reliability of the connector 10 and reduces the occurrence of unexpected jamming failures. In addition, the geometric relationship between the abutment portion 1113 and the locking groove 1112 optimizes the guidance between the connectors 10, ensuring smooth docking in practical applications.

[0114] Specifically, referring to Figure 12, when the two sets of connecting parts 10 are mated and the mounting cavity 1111 is connected to the locking groove 1112, the limiting pin 210 in one set of connecting parts 10 can be sleeved on the abutting part 1113 in the other set of connecting parts 10.

[0115] With this configuration, during the docking process of the two sets of connecting members 10, the abutment portion 1113 can drive the switch pin 220 to move to the second position. At this time, the locking member 230 releases the limiting pin 210. After the mounting cavity 1111 of one set of connecting members 10 is aligned with the locking groove 1112 of the other set of connecting members 10, the limiting pin 210 can be moved relative to the connecting member 100 by adjusting the operating mechanism 300, so that the limiting pin 210 is inserted into the locking groove 1112 and sleeved on the abutment portion 1113, thereby realizing the connection limiting function of the limiting component 200. In this embodiment, by setting the abutment portion 1113 to cooperate with the limiting pin 210, the overall structure of the limiting component 200 can be compact when connecting the two sets of connecting members 10.

[0116] The distance between the outer wall of the limiting pin 210 in one set of connecting parts 10 and the inner wall of the locking groove 1112 in another set of connecting parts 10 is G1, and the distance between the inner wall of the limiting pin 210 in one set of connecting parts 10 and the outer wall of the abutment part 1113 in another set of connecting parts 10 is G2, and G2>G1.

[0117] In this embodiment, by limiting dimensions G1 and G2, it can be ensured that when the two sets of connectors 10 are mated, if the limiting pin 210 is not precisely coaxially aligned with the abutment portion 1113, the outer wall of the limiting pin 210 will first contact the inner wall of the locking groove 1112. At this time, G2 being greater than G1 can effectively prevent the inner wall of the limiting pin 210 from contacting the outer wall of the abutment portion 1113. The advantage of this setting is that the cooperation between the limiting pin 210 and the inner wall of the locking groove 1112 can guide the insertion, thereby effectively preventing the limiting pin 210 from accidentally contacting and damaging the abutment portion 1113 during the mating process, ensuring the overall stability and safety of the system, and reducing the maintenance cost of the connectors 10.

[0118] It should be noted that if G2 is not greater than G1, the limit pin 210 may collide with the abutment part 1113 during docking and damage the abutment part 1113. Once the abutment part 1113 is damaged, the entire connecting component 100 needs to be replaced, which is not conducive to reducing the maintenance cost of the connecting component 10.

[0119] Please refer to Figure 2. In one embodiment, the locking groove 1112 and the mounting cavity 1111 are spaced apart circumferentially along the connecting member 100.

[0120] In one embodiment, the mounting cavity 1111 and the locking groove 1112 are arranged along the circumferential direction of the connecting member 100, and the two sets of connecting members 10 can be rotated and connected. By arranging the mounting cavity 1111 and the locking groove 1112 at intervals along the circumferential direction of the connecting member 100, when the two sets of connecting members 10 are connected, the mounting cavity 1111 of one set of connecting members 100 can be connected with the locking groove 1112 of the other set of connecting members 10, thereby achieving an effective connection.

[0121] This geometric layout design ensures that the switch pins 220 in the two sets of connectors 10 can abut against the abutment portion 1113 of the other set of connectors 10, and allow the switch pins 220 to move smoothly to the second position. At the same time, under the driving action of the operating mechanism 300, the limit pins 210 in the two sets of connectors 10 can engage with the locking grooves 1112 in the other set of connectors 10, thereby realizing the locking function.

[0122] Of course, in some embodiments, when the connecting members 100 in the two sets of connecting members 10 are radially inserted, the mounting cavity 1111 and the locking groove 1112 can also be arranged radially along the connecting member 10. This arrangement can further improve the flexibility of the connecting members and provide a more convenient docking method when needed. At the same time, the limiting component 200 can also effectively limit the two sets of connecting members 10 to prevent accidental loosening or displacement, thereby enhancing the stability and safety of the overall device.

[0123] Furthermore, the specific materials for the switch pin 220 and limit pin 210 can be steel, aluminum, or engineering plastics, with the specific selection optimized based on factors such as structural strength, weight, and cost to achieve the best balance of material properties. Therefore, in practical applications, the proper setting of these parameters will directly affect the performance and service life of the connecting parts.

[0124] Furthermore, the end of the switch pin 220 facing the outer side of the outer mounting cavity 1111 has a smooth structure.

[0125] This design allows the smooth structure to contact the other set of connecting members 10 during relative movement of the switch pin 220, thereby significantly improving the smoothness of the switch pin 220's movement. For example, when the two sets of connecting members 10 rotate relative to each other, and the edge of the mounting cavity 1111 or locking groove 1112 comes into contact with the switch pin 220, the smooth structure can guide the movement of the switch pin 220, preventing the switch pin 220 from directly abutting against the mounting cavity 1111 or locking groove 1112 and affecting the relative rotation between the two sets of connecting members 10.

[0126] Specifically, the smooth structure can be a rounded corner structure, a chamfered structure, or other similar smooth surface machined at the end of the switch pin 220. Using a rounded corner structure can effectively reduce wear on the contact edges and improve durability; while a chamfered structure can enhance the adaptability of the switch pin 220 to misalignment and impacts during assembly and use. Furthermore, the smooth structure design can also reduce friction between the switch pin 220 and other contacting parts, reducing energy consumption and improving operational flexibility.

[0127] In one embodiment, the connector 10 has a connecting surface 1114 that mates with another set of connectors 10. When the two sets of connectors 10 are mated, the connecting surfaces 1114 of the two connectors 10 are arranged opposite to each other, and the openings of the locking groove 1112 and the mounting cavity 1111 are both located on the connecting surface 1114.

[0128] Specifically, when the two sets of connectors 10 are docked, the switch pin 220 of one set of connectors 10 can abut against the connecting surface 1114 of the other set of connectors 10 and move to the second position. In this embodiment, when the two sets of connectors 10 are docked, the switch pin 220 first contacts the connecting surface 1114. During the connection process, the switch pin 220 moves smoothly to the second position by the contact surface 1114 abutting against the switch pin 220 of the other set of connectors 10. At this time, the connecting surface 1114 can effectively restrict the movement of the limiting pin 210 until the two sets of connectors 10 rotate until the mounting cavity 1111 of one set of connectors 10 aligns with the locking groove 1112 of the other set of connectors 10. Subsequently, the operating mechanism 300 can drive the limiting pin 210 to be inserted into the locking groove 1112, thereby achieving relative rotational limitation of the two sets of connectors 10 through the cooperation of the limiting pin 210 and the locking groove 1112.

[0129] It should be noted that in some embodiments, an additional guide surface can be provided on the connecting member 100 to guide the switch pin 220. This guide surface can be inclined, planar, or of other geometric shapes to adapt to different working conditions and installation requirements. By providing an additional guide surface, the accuracy and stability of the connection between the switch pin 220 and the connecting member 10 can be improved, reducing damage caused by misalignment during the connection process. Furthermore, unlocking elements such as electric push rods or cylinders can be configured to cooperate with the switch pin 220, thereby achieving precise control and position adjustment of the switch pin 220. This configuration not only facilitates operation but also enhances the responsiveness of the entire device under dynamic conditions, contributing to improved overall system efficiency and performance.

[0130] Specifically, the limiting pin 210 and the switch pin 220 are movably housed in the same mounting cavity 1111. The connecting member 100 is provided with an output port 11111 that communicates with the mounting cavity 1111. When the switch pin 220 is in the second position, the limiting pin 210 can extend out from the output port 11111. When the switch pin 220 moves from the second position to the first position, the switch pin 220 extends out from the output port 11111.

[0131] This configuration allows both the limit pin 210 and the switch pin 220 to extend from the same output port 11111 of the mounting cavity 1111, making the overall structure of the limit assembly 200 more compact. This allows the diameter of the limit assembly 200 to be set as large as possible, thereby improving the overall strength of the limit assembly 200. Specifically, when the two sets of connectors 10 are mated, the output port 11111 of one set of connectors 10 can be aligned with the locking groove 1112 of the other set of connectors 10. Then, by adjusting the operating mechanism 300, the limit pin 210 can be driven to extend from the output port 11111 and be inserted into the locking groove 1112 to complete the limiting function of the limit assembly 200.

[0132] In this embodiment, the design allows the limiting pin 210 and the switch pin 220 to operate within the same cavity, thereby reducing the relative movement space between components and thus reducing the installation volume. This compact structure not only improves the space utilization of the design but also enhances the compressive and torsional stiffness of the limiting component 200 when subjected to external forces.

[0133] Furthermore, the limiting pin 210 is sleeved on the outside of the switch pin 220 and slides relative to the switch pin 220.

[0134] By positioning the limit pin 210 on the outside of the switch pin 220, the overall structure of the limit assembly 200 can be made compact. This design provides greater space utilization, allowing the limit pin 210 to have a larger diameter, thereby significantly improving its strength and enhancing the load-bearing capacity and stability of the limit assembly 200 during use.

[0135] Furthermore, the design of the limit pin 210 helps to effectively guide the movement of the switch pin 220. Since the limit pin 210 covers the outside of the switch pin 220, its sliding fit improves the movement accuracy between the two, ensuring proper engagement of the switch pin 220 with the other set of connecting parts 10 during opening and closing. This guiding structure not only reduces wear during operation but also reduces the probability of failure, further improving the efficiency and service life of the components.

[0136] Referring to Figures 3, 4, and 12, in one embodiment, the inner wall of the mounting cavity 1111 is provided with a locking groove 11112, the limiting pin 210 has a communicating movable cavity 211 and a connecting hole 212, the switch pin 220 is movably accommodated in the movable cavity 211, and the locking member 230 is movably connected in the connecting hole 212; in the first position, the locking member 230 is simultaneously engaged with the connecting hole 212 and the locking groove 11112; in the second position, the locking member 230 can be separated from the locking groove 11112.

[0137] Thus, when the switch pin 220 is in the first position, the locking member 230 in the connecting hole 212 can at least partially connect with the locking groove 11112, thereby effectively fixing the limit pin 210 and the connecting member 100 together. When the switch pin 220 moves to the second position, the locking member 230 can separate from the locking groove 11112, a process that unlocks the limit pin 210 and the connecting member 100. In one embodiment, the switch pin 220 and the locking member 230 can be connected by a flexible connector. When the switch pin 220 moves to the second position relative to the limit pin 210, the connector can pull the locking member 230 out of the locking groove 11112 to separate the two, thereby realizing the unlocking function. When the switch pin 220 moves toward the first position, the connector can abut against the locking member 230 and drive the locking member 230 to connect with the locking groove 11112. Specifically, the connector can be a flexible element such as a spring or a steel sheet, and is not limited to this specific element.

[0138] It should be noted that the length of the locking member 230 along the axial direction of the connecting hole 212 can be set such that, in the first position, the length of the locking member 230 is not greater than the length of the connecting hole 212, so as to prevent the locking member 230 from protruding from the connecting hole 212 toward the locking groove 11112.

[0139] In one embodiment, the outer wall of the switch pin 220 is provided with a movable groove 221; in the first position, the switch pin 220 abuts against the locking member 230 so that the locking member 230 is simultaneously engaged with the connecting hole 212 and the locking groove 11112; in the second position, the locking member 230 is at least partially accommodated in the movable groove 221 and can be separated from the locking groove 11112.

[0140] With this configuration, when the switch pin 220 is in the first position, the locking member 230 can pass through the connecting hole 212 and connect with the locking groove 11112 through the abutting action, thereby effectively fixing the limiting pin 210 and the connecting member 100 together. When the switch pin 220 moves to the second position, the movable groove 221 connects with the connecting hole 212, allowing the locking member 230 to move smoothly into the movable groove 221. This process unlocks the limiting pin 210 and the connecting member 100. At the same time, the movable groove 221 extends along the axial direction of the limiting pin 210, and the locking member 230 can move together with the movement of the limiting pin 210. With this structural configuration, the overall structure of the limiting assembly 200 is more compact, thereby increasing the outer diameter of the limiting pin 210 and the switch pin 220, and thus enhancing the overall strength of the limiting assembly 200.

[0141] It should be noted that the length of the locking member 230 along the axial direction of the connecting hole 212 can be set as follows: In the first position, the depth of the locking groove 11112 is less than or equal to the length of the locking member 230 and the length of the connecting hole 212 plus the depth of the locking groove 11112. This ensures that the locking member 230 can be locked with the connecting hole 212 and the locking groove 11112, while preventing the locking member 230 from failing to return to the connecting hole 212 from the locking groove 11112. In the second position, the depth of the movable groove 221 is less than or equal to the length of the locking member 230 and the length of the connecting hole 212 plus the depth of the movable groove 221. This ensures that the locking member 230 can separate from the locking groove 11112 to release the limiting pin 210, while preventing the locking member 230 from failing to return to the connecting hole 212 from the movable groove 221.

[0142] Furthermore, the movable groove 221 includes a first groove portion 2211 and a second groove portion 2212 that are connected to each other. The depth of the first groove portion 2211 is less than that of the second groove portion 2212. In the first position, the locking member 230 is respectively accommodated in the first groove portion 2211, the connecting hole 212 and the locking groove 11112. In the second position, the locking member 230 is respectively accommodated in the second groove portion 2212 and the connecting hole 212.

[0143] In this embodiment, by respectively providing the cooperation of the first groove 2211 and the second groove 2212, when the switch pin 220 is in the first position, the inner wall of the first groove 2211 can abut against the locking member 230. This design allows the locking member 230, in its accommodating state within the first groove 2211, to effectively limit the movement of the switch pin 220 along the direction from the second groove 2212 to the first groove 2211, thereby making the connection of the limiting assembly 200 more stable in the first position.

[0144] When the switch pin 220 moves to the second position, the locking member 230 can be smoothly accommodated in the second groove 2212. At this time, the locking member 230 will release the limiting pin 210 and the connecting member 100, effectively realizing the unlocking function. The advantage of this design is that by setting two grooves of different sizes, the movement path of the locking member 230 can be effectively controlled, thereby enhancing the stability and safety of the limiting assembly 200.

[0145] It should be noted that the depth difference design between the first groove 2211 and the second groove 2212 not only helps to ensure the stable connection of the limit pin 210, but also, in practical applications, the depth of the first groove 2211 can be set to 1mm, 2mm, or 3mm according to actual needs, and the depth of the second groove 2212 can be set to 4mm, 5mm, or 6mm, etc. The specific depth is determined according to actual design requirements and is not a single limitation here. When the depths of the first groove 2211 and the second groove 2212 are not within this preferred range, it may cause the locking member 230 to jam or become unstable during state transitions, thereby affecting the overall performance of the component. Through reasonable design and selection, the efficient and stable operation of the limit component 200 can be ensured.

[0146] Specifically, the length of the locking member 230 along the axial direction of the connecting hole 212 can be set as follows: In the first position, the depth of the locking groove 11112 is less than or equal to the length of the locking member 230 and the depth of the first groove 2211 plus the length of the connecting hole 212 plus the depth of the locking groove 11112. This ensures that the locking member 230 can be locked with the first groove 2211, the connecting hole 212, and the locking groove 11112, while preventing the locking member 230 from failing to return to the connecting hole 212 from the locking groove 11112. In the second position, the depth of the second groove 2212 is less than or equal to the length of the locking member 230 and the length of the connecting hole 212 plus the depth of the second groove 2212. This ensures that the locking member 230 can release the limiting pin 210, while preventing the locking member 230 from failing to return to the connecting hole 212 from the second groove 2212.

[0147] In one embodiment, a limiting wall is formed on the side of the first groove 2211 away from the second groove 2212.

[0148] In this embodiment, a limiting wall surface is formed on the side of the first groove 2211 away from the second groove 2212. This allows the locking member 230, when housed within the first groove 2211, to abut against the locking member 230, effectively limiting the movement of the switch pin 220 along the direction from the second groove 2212 to the first groove 2211. This makes the connection of the limiting assembly 200 more stable in the first position. It should be noted that the force borne by the limiting wall surface during limiting primarily comes from the reverse force of the locking member 230. The limiting wall surface can be set as an inclined surface, and its angle can be adjusted within a certain range to adapt to different working environments and strength requirements. Specifically, the inclination angle of the limiting wall surface can be adjusted between 15° and 30°, with specific values ​​of 15°, 20°, 25°, or 30°, determined according to actual design requirements and not limited to a single value.

[0149] In one embodiment, the first groove 2211 and the second groove 2212 are connected to form a stepped surface 2213, and the stepped surface 2213 can abut against the locking member 230 in the second position.

[0150] In this embodiment, a stepped surface 2213 is formed between the first groove 2211 and the second groove 2212. When the locking member 230 moves into the second groove 2212, and the switch pin 220 tends to move outward toward the mounting cavity 1111, the locking member 230 can abut against the stepped surface 2213 to limit the movement of the switch pin 220. It should be noted that when the locking member 230 is limited, the force it bears mainly comes from the reverse force of the switch pin 220. The angle design of the stepped surface 2213 can be adjusted within a certain range to adapt to different working environments and strength requirements. Specifically, the inclination angle of the stepped surface 2213 can be adjusted between 15° and 30°, with specific values ​​of 15°, 20°, 25°, or 30°, determined according to actual design requirements, and is not limited to a single value here.

[0151] Referring to Figure 8, in one embodiment, the outer wall of the limiting pin 210 is provided with a plurality of driving teeth 213 arranged sequentially along its axial direction, the operating mechanism 300 is provided with a plurality of driving tooth grooves 311, the operating mechanism 300 is movably connected to the connecting member 100, and the driving teeth 213 are connected to the driving tooth grooves 311 in a transmission manner.

[0152] It should be noted that the number of drive teeth 213 can be one, two, or more, and there is no single limitation. Setting multiple drive teeth 213 to cooperate with drive tooth grooves 311 can improve the stability of drive contact and the transmitted force, especially under high load conditions, which can effectively improve the reliability and response speed of the system.

[0153] In specific implementations, the drive tooth 213 can adopt a sawtooth, helical, or other suitable tooth profile design to balance transmission efficiency and manufacturing cost. If a sawtooth tooth profile is adopted, slippage can be better prevented during the drive process, and the meshing degree between the teeth can be enhanced; if a helical tooth profile is selected, noise and vibration can be reduced when transmitting force in a specific direction, and the overall stability of operation can be improved.

[0154] In a preferred embodiment, the drive tooth 213 and the drive tooth groove 311 can be arc-shaped structures. This configuration can reduce the manufacturing cost of the operating mechanism 300 and the limit pin 210 while ensuring stable connection between the two.

[0155] During the design process, appropriate materials and structures need to be selected based on the specific application environment. For example, if the ambient temperature is high, the limit pin 210 and the operating mechanism 300 should be made of high-temperature resistant materials to prevent accelerated tooth wear and reduced mechanical performance. Specifically, the selected materials can be aluminum alloys, special plastics, etc., and their suitability under conditions of mechanical wear and corrosion should be considered.

[0156] Furthermore, referring to Figures 4 and 8, the limiting pin 210 is also provided with a first anti-rotation groove 214, which is connected to the movable cavity 211; the switch pin 220 is provided with a second anti-rotation groove 223; the limiting assembly 200 also includes an anti-rotation member 240, which is detachably connected to the connecting member 100, and the anti-rotation member 240 is at least partially inserted into the first anti-rotation groove 214 and the second anti-rotation groove 223 in sequence.

[0157] When assembling the limiting component 200 of this embodiment, the switch pin 220 and the limiting pin 210 are first nested and then inserted into the mounting cavity 1111. Next, the first anti-rotation groove 214 of the limiting pin 210 is correspondingly set with the second anti-rotation groove 223 of the switch pin 220. Subsequently, the anti-rotation member 240 is connected to the connecting member 100, and the anti-rotation member 240 engages with the first anti-rotation groove 214 and the second anti-rotation groove 223 respectively, to effectively limit the rotation of the limiting pin 210 and the switch pin 220 relative to the connecting member 100, ensuring that the limiting component 200 has high operational accuracy.

[0158] Meanwhile, this embodiment also provides a mating positioning for the drive tooth 213 and the drive tooth groove 311 to enhance operational stability and accuracy, and reduce frictional loss between them. In some embodiments, the anti-rotation member 240 can be threadedly connected to the connecting member 100 for easy assembly and disassembly. Specifically, the locking member 230 is a ball or a cylinder, and the locking member 230 slides in fit with the connecting hole 212.

[0159] In practical implementation, if the locking element 230 is chosen to be a ball, it can provide lower friction within the connecting hole 212, thereby reducing wear and extending its service life. The ball structure design can also adapt to certain angle changes, making the connection more flexible and stable. In addition, the shape of the ball helps to distribute the load evenly, reduce stress concentration, and help improve the reliability of the overall mechanical system.

[0160] However, if a column is chosen as the locking element 230, it is more suitable for applications requiring high-precision positioning. The planar contact design of the column provides a more stable positioning effect and reduces the risk of failure due to vibration or impact in the corresponding working environment.

[0161] Referring to Figures 3 and 4, in one embodiment, the limiting component 200 further includes an elastic element 250, which is housed in the mounting cavity 1111 and is connected to the switch pin 220 and the connecting member 100 respectively. The elastic element 250 is used to drive the switch pin 220 to move from the second position toward the first position.

[0162] In this embodiment, by configuring the elastic element 250 to cooperate with the switch pin 220, when the force generated by the external drive is removed, the elastic element 250 can automatically drive the switch pin 220 to reset to the first position using its elastic properties. The advantage of this design is that it ensures the stability of the limit pin 210, avoids accidental extension caused by external force interference, and thus improves the safety and reliability of the entire system.

[0163] Specifically, the elastic element 250 can be selected from various types of elastic elements, such as compression springs, tension springs, or gas springs. Compression springs have the advantage of providing a large restoring force, making them suitable for applications requiring a fast return speed; tension springs can achieve a large tensile force in a compact space and are not easily compressed or deformed, making them suitable for designs with limited space; gas springs provide a smoother force transmission, making them suitable for applications requiring precise motion control.

[0164] Specifically, the switch pin 220 is provided with a fixing part 222, one end of the elastic member 250 is sleeved on the fixing part 222, and the other end of the elastic member 250 abuts against the end face of the mounting cavity 1111.

[0165] In this embodiment, the elastic element 250 can be a helical spring, and the elastic element 250 is sleeved on the fixing part 222, resulting in a simple structure and convenient assembly. The design of the helical spring allows it to generate a large restoring force after being subjected to external force, effectively driving the switch pin 220 to reset to the first position. The advantage of this design is that the helical spring can achieve the required elastic force in a small space, making the overall structure of the limiting component 200 more compact. In addition, the manufacturing process of helical springs is relatively mature and the cost is low, thereby helping to reduce the overall production cost.

[0166] Referring to Figures 9 to 11, in one embodiment, the operating mechanism 300 includes an operating handle 310 and a positioning component 320. The operating handle 310 is rotatably connected to the connecting member 100 and is also throttle-connected to the limiting pin 210. The positioning component 320 is movably connected to the operating handle 310. The outer wall of the connecting member 100 is provided with a plurality of positioning grooves 1115, and the plurality of positioning grooves 1115 are arranged sequentially along the rotation direction of the operating handle 310. The positioning component 320 is used to engage with the positioning grooves 1115 respectively.

[0167] By cooperating with the positioning component 320 and the operating handle 310, the positioning component 320 can be easily unlocked from the positioning slot 1115 when the operating handle 310 needs to be adjusted. This design allows the user to flexibly adjust the angle or position of the operating handle 310, improving operational flexibility. After the operating handle 310 is adjusted to the target position, the positioning component 320 can engage with the corresponding positioning slot 1115, thereby effectively limiting the movement of the operating handle 310, ensuring the locking stability of the limiting component 200, and preventing functional failure or component damage due to misoperation.

[0168] It should be noted that the number of positioning slots 1115 can be three, four, or more, depending on the specific design requirements of the operating handle 310. No single limitation is imposed here. Adding multiple positioning slots 1115 provides more flexible positioning options, ensuring stable locking of the operating handle 310 in different functional states, thus enhancing the operability and safety of the system. If the number of positioning slots is too small, the adjustment range may be limited, thereby affecting operational flexibility. Specifically, referring to Figure 11, the operating handle 310 has a connected receiving cavity 312 and a movable hole 3121; the positioning component 320 includes a handle unlocking component 321 and a handle positioning component 322. The handle positioning component 322 is movably connected to the movable hole 3121. The outer wall of the handle unlocking component 321 is provided with an unlocking groove 3211, and the handle unlocking component 321 is slidably connected to the receiving cavity 312 and can move between a third position and a fourth position. In the third position, the handle positioning component 322 is respectively accommodated in the movable hole 3121 and the positioning groove 3115. In the fourth position, the handle positioning component 322 is respectively accommodated in the movable hole 3121 and the unlocking groove 3211.

[0169] With this configuration, when the operating handle 310 needs to be unlocked, the user only needs to press the handle unlocking component 321, causing it to enter the receiving cavity 312, and aligning the unlocking groove 3211 with the movable hole 3121. This allows the handle positioning component 322 to move smoothly into the unlocking groove 3211 and separate from the positioning groove 1115. This operation is simple and suitable for applications requiring frequent adjustments, thus improving efficiency. Furthermore, by placing the positioning component 320 within the receiving cavity 312, the overall structure becomes compact, reducing the size of the operating mechanism 300 and improving the integrability and portability of the connector 10.

[0170] Furthermore, the positioning component 320 also includes a handle reset member 323, which is housed in the receiving cavity 312 and is connected to the handle unlock member 321 and the operating handle 310 respectively. The handle reset member 323 is used to drive the handle unlock member 321 to move from the fourth position toward the third position.

[0171] In this embodiment, the handle reset member 323 can be designed as a spring structure or a flexible material, so that it can automatically return to its initial position after the handle unlock member 321 is pressed and unlocked. The advantage of this design is that it can improve the convenience of operating the handle 310 and ensure that the handle unlock member 321 can quickly reset after each operation, avoiding misoperation or locking failure caused by the failure to restore the position.

[0172] Specifically, the handle reset component 323 can be a compression spring, a tension spring, or other active reset devices such as an electric actuator or cylinder. The choice of these reset components can provide users with different feel and operating experiences. For example, a compression spring can provide a larger reset force in a small space, while a tension spring is suitable for applications requiring a longer stroke.

[0173] In one embodiment, the handle unlocking member 321 may have a slot on the side facing the handle reset member 323, and the handle reset member 323 may be at least partially accommodated within the slot. The advantage of this design is that it improves the overall structural compactness of the positioning assembly 320, reduces space occupation, and helps improve the integration and aesthetics of the device. Furthermore, this design allows the handle reset member 323 to be more securely fixed to the handle unlocking member 321, thereby improving the stability of the assembly and reducing the risk of displacement due to vibration or other factors during use.

[0174] Specifically, the operating handle 310 also has a mounting hole a3122 communicating with the receiving cavity 312, and the positioning component 320 also includes a handle sealing member 324, which is detachably connected to the mounting hole a3122. The handle reset member 323 abuts against the handle unlocking member 321 and the handle sealing member 324 respectively.

[0175] When assembling the positioning component 320 of this embodiment, the handle unlocking component 321 and the handle positioning component 322 can be inserted into the receiving cavity 312 through one end of the mounting hole a3122, with one end of the handle unlocking component 321 extending outside the receiving cavity 312. Then, the handle reset component 323 is pressed onto the other end of the handle unlocking component 321, and finally, the handle sealing component 324 is connected to the operating handle 310, thereby sealing the mounting hole a3122. This design has the advantages of simple structure and convenient assembly, ensuring that users can quickly and efficiently assemble and maintain the component.

[0176] Specifically, the handle sealing element 324 and the mounting hole a3122 can be connected by threads. In this embodiment, the advantage of the threaded connection is that it provides good sealing and stability, effectively preventing loosening of components due to vibration. At the same time, the threaded connection also makes it easier to disassemble and replace the handle sealing element 324, further improving the maintainability of the equipment.

[0177] Referring to Figures 3 to 7, in one embodiment, the connecting member 100 has a valve core cavity 1117 communicating with the flow channel inside. The connecting member 10 also includes a valve core assembly 400, which is movably housed in the valve core cavity 1117. The valve core assembly 400 is connected to the operating mechanism 300, and the operating mechanism 300 is used to drive the valve core assembly 400 to move between closing and opening the flow channel.

[0178] In this embodiment, by driving the operating mechanism 300, not only can the limiting connection between the limiting pin 210 and another set of connecting parts 10 be controlled, but the valve core assembly 400 can also be driven to effectively open the flow channel. This configuration ensures that the flow channel is opened by the valve core assembly 400 only after the limiting pin 210 and the connecting part 10 are securely connected. This prevents the flow channel from opening unexpectedly before the connecting part 10 is properly installed, thereby improving the connection reliability of the connecting part 10.

[0179] During the operation of the valve core assembly 400, its range of motion should be appropriately designed to ensure smooth transition between the closed and open positions. Specifically, the range of motion of the valve core assembly 400 can be set within a certain angle or linear displacement range, such as an angle range of 0° to 90°, or a linear displacement range of 0mm to 20mm. In this design, the opening angle and displacement of the valve core assembly 400 should be combined with specific application requirements to avoid fluid control instability caused by design flaws. By optimizing the range of motion of the valve core assembly, the accuracy and safety of flow control can be effectively improved.

[0180] Specifically, referring to Figure 6, the valve core assembly 400 includes a valve core body 410 and a valve core spindle structure 420. The valve core body 410 is rotatably connected to the connecting member 100 through the valve core spindle structure 420. The operating mechanism 300 is connected to the valve core spindle structure 420 and is used to drive the valve core body 410 to rotate relative to the connecting member 100.

[0181] In this embodiment, the valve core 410 is rotatably connected to the connecting member 100 via the valve core spindle structure 420, making the adjustment process of the valve core 410 smoother and more stable. The advantage of using a rotary adjustment method for the valve core 410 is that it provides higher sealing performance and lower resistance, making it particularly suitable for ball valve applications. In this design, the valve core 410 can be spherical, ensuring no fluid leakage during opening and closing, and providing low flow resistance, thereby improving fluid flow efficiency. The shape and material selection of the valve core 410 are also quite important. The valve core 410 can be made of metallic materials, such as stainless steel or copper alloy, which enhances its corrosion resistance and service life.

[0182] In one embodiment, the connecting member 100 is further provided with a first hole 11171 and a second hole 11172 respectively communicating with the valve core cavity 1117, and the first hole 11171 and the second hole 11172 are coaxially arranged; the valve core spindle structure 420 includes a valve core drive shaft 421 and a valve core plug 422, the valve core drive shaft 421 passes through the first hole 11171 and is respectively connected to the operating mechanism 300 and the valve core body 410, and the valve core plug 422 is detachably connected to the second hole 11172 and rotatably connected to the valve core body 410.

[0183] When assembling the connector 10 in this embodiment, the valve core body 410 can first be installed into the valve core cavity 1117. Then, it can be connected to the valve core body 410 from both ends of the first hole 11171 and the second hole 11172 via the valve core drive shaft 421 and the valve core plug 422. The valve core plug 422 can seal the second hole 11172, and the valve core drive shaft 421 can seal the first hole 11171, thereby ensuring no fluid leakage. This design not only improves the ease of assembly but also ensures the sealing performance of the valve core assembly.

[0184] Specifically, the valve core drive shaft 421 can be made of stainless steel, aluminum alloy, or engineering plastics to provide good strength and corrosion resistance. Meanwhile, the valve core plug 422 can be connected by a threaded connection or a snap-fit ​​mechanism for easy disassembly and maintenance. The advantage of this structural design is that if the valve core body 410 needs to be replaced or maintenance is required, the operator can quickly and easily do so by disassembling the valve core plug 422, reducing downtime and improving the system's ease of use.

[0185] Specifically, the valve core spindle structure 420 also includes a valve core fastener 423. The valve core drive shaft 421 passes through the operating handle 310 and is fixedly connected to the operating handle 310 by the valve core fastener 423.

[0186] It should be noted that the valve core fastener 423 can be a screw, nut, pin, or other compatible fastener, depending on the actual design requirements, and is not limited to a single type. Choosing suitable fasteners not only ensures the stability of the structure but also improves the overall strength and durability of the valve core spindle structure.

[0187] The advantage of using screws as valve core fasteners 42 is their ease of installation and disassembly, as well as their good vibration and loosening resistance, making them particularly suitable for applications requiring frequent operation. Choosing pins, on the other hand, can further enhance the tensile and shear strength of the connection point, making them suitable for mechanical components with higher safety requirements. Furthermore, the material of valve core fasteners 423 can be selected according to the application environment, such as stainless steel, carbon steel, or engineering plastics, to improve corrosion resistance and adaptability to different working conditions.

[0188] Furthermore, the valve core spindle structure 420 also includes a drive sealing ring 424, which is sleeved on the valve core drive shaft 421 and seals between the valve core drive shaft 421 and the first hole 11171.

[0189] In this embodiment, the drive seal ring 424 effectively prevents fluid leakage between the valve core drive shaft 421 and the valve core cavity 1117, ensuring the system's sealing performance and reliability. Specifically, the drive seal ring 424 can be made of materials such as rubber, polyurethane, or polytetrafluoroethylene (PTFE). The advantage of this specific implementation is that seal rings made of different materials can adapt to different working environments. For example, rubber seal rings have good elasticity and sealing performance, making them suitable for high-frequency dynamic sealing applications; while polytetrafluoroethylene (PTFE) has excellent corrosion resistance and high-temperature resistance, making it suitable for use in harsh chemical environments.

[0190] In one embodiment, the valve core assembly 400 further includes a valve core sealing seat 430, which communicates with the flow channel and seals between the inner wall of the valve core cavity 1117 and the outer wall of the valve core body 410.

[0191] The design of the valve core seal seat 430 ensures an effective seal between the valve core body 410 and the valve core cavity 1117, preventing fluid leakage and thus improving the overall efficiency and safety of the system. In specific implementations, the valve core seal seat 430 can be made of materials such as rubber, polyurethane, or polytetrafluoroethylene (PTFE), each possessing good elasticity and corrosion resistance, enabling it to adapt to different working environments. Selecting appropriate materials not only optimizes sealing performance but also extends the service life of the valve core assembly.

[0192] The function of the valve core sealing seat 430 is not limited to sealing; it also positions the valve core body 410 during installation, ensuring the stability and accuracy of the valve core body within the valve cavity, thereby improving the valve's response speed and control precision. Specifically, the shape and size design of the valve core sealing seat 430 should match the valve core body 410 to ensure it is securely fixed during installation and to reduce movement clearance.

[0193] Furthermore, the valve core assembly 400 also includes a valve core sealing ring 440, and a valve core sealing groove 431 is provided on the side of the valve core sealing seat 430 away from the valve core body 410. The valve core sealing ring 440 is housed in the valve core sealing groove 431 and sealed between the valve core sealing seat 430 and the valve core cavity 1117.

[0194] In this embodiment, the valve core sealing ring 440 effectively enhances the overall sealing performance of the valve core assembly, further preventing fluid leakage during operation, thereby improving the safety and reliability of the system. Specifically, the valve core sealing ring 440 can be made of materials such as rubber, silicone, polyurethane, or polytetrafluoroethylene (PTFE), all of which possess good elasticity and corrosion resistance. Rubber sealing rings offer good compressibility and flexibility, making them suitable for low-pressure environments; while PTFE sealing rings, due to their excellent high-temperature resistance and chemical resistance, are more suitable for sealing requirements in high-temperature or corrosive environments. This flexible material selection not only improves the applicability of the valve core assembly but also extends the service life of the sealing ring and reduces maintenance frequency.

[0195] It should be noted that the shape and size of the valve core sealing groove 431 should match the valve core sealing ring 440. Specifically, the depth of the sealing groove can be designed to be 2mm to 6mm, including 2mm, 4mm, 6mm and other intermediate values, to ensure that the sealing ring can be firmly placed in the groove and provide a good sealing effect.

[0196] Referring to Figure 7, in one embodiment, the connecting member 100 includes a body 111 and a connecting part 112. The mounting cavity 1111 and the valve core cavity 1117 are both provided on the body 111. The connecting part 112 is detachably connected to the body 111 and passes through the body 111. The connecting part 112 and the body 111 enclose the valve core cavity 1117. The connecting part 112 is used to connect to an external pipeline.

[0197] The use of a split-type connecting component 100 has significant advantages, particularly since one end opening of the valve core cavity 1117 is located on the outer wall of the body 111, which simplifies the installation process of the valve core 410. Specifically, the valve core 410 can be easily inserted through the opening of the valve core cavity 1117. This design allows users to perform maintenance and replacement without completely disassembling the entire connecting component 100, effectively saving time and improving operational convenience.

[0198] Furthermore, the detachable design of the connecting part 112 further enhances the overall ease of assembly and disassembly, facilitating quick processing by users during maintenance or replacement. Specifically, the connecting part 112 can be connected by threaded connection, snap-fit ​​connection, or plug-in connection, each with its own advantages. For example, threaded connection provides good sealing, while plug-in connection facilitates quick assembly and disassembly. It should be noted that the specific connection method should be selected based on actual application requirements, and no single limitation is made here.

[0199] Furthermore, the connecting member 100 also includes a valve seat sealing ring 114, which is sleeved on the connecting part 112 and seals between the connecting part 112 and the body part 111.

[0200] Specifically, the valve seat seal 114 is designed to improve the overall system's sealing performance, preventing fluid leakage and ensuring stable equipment operation. In some embodiments, the valve seat seal 114 can be made of materials such as rubber, polyurethane, or polytetrafluoroethylene (PTFE). It should be noted that the size and shape of the valve seat seal 114 should be adapted to the contact surfaces of the connecting portion 112 and the body portion 111. The thickness of the seal can be set to 2mm, 4mm, or 6mm, etc., and selected according to actual design requirements. If the thickness of the seal exceeds or falls below this range, insufficient sealing performance may occur, leading to leakage problems and affecting the overall efficiency and safety of the equipment.

[0201] Referring to Figures 7 and 9, in one embodiment, the body 111 has a through mounting slot 1116 extending through it, and the connecting member 100 also includes a valve seat snap ring 113, which is accommodated in the mounting slot 1116 and engages with the connecting part 112.

[0202] In this embodiment, the design of the mounting slot 1116 not only simplifies the installation process of the valve seat retaining ring 113 and improves the convenience of maintenance, but also effectively reduces errors introduced by manual operation. When assembling the connecting component 100 of this embodiment, after the connecting part 112 is installed in the body part 111, the valve seat retaining ring 113 can be inserted through the mounting slot 1116 and clamped onto the connecting part 112, thereby achieving a fixed connection between the connecting part 112 and the body part 111.

[0203] It should be noted that the valve seat retaining ring 113 can be made of different materials, such as stainless steel, carbon steel, or plastic. Stainless steel offers good corrosion resistance and can withstand high pressure, making it suitable for applications involving corrosive fluids. Carbon steel offers good strength and economy in general environments, while plastic materials are known for their lightweight and low cost, making them suitable for low-load applications. The specific material selection should be optimized based on actual design requirements and is not limited to a single material here.

[0204] Furthermore, the number of valve seat retaining rings 113 can be one, two, or more. The specific number can be determined according to actual needs to improve the fixing effect of the connecting part 112 and enhance its stability. For example, using multiple valve seat retaining rings 113 can significantly improve the locking performance in environments with vibration or pressure changes, thereby effectively preventing the loosening and leakage of the connecting member 100, thus ensuring the safety and reliability of the connecting member 10.

[0205] Specifically, referring to Figures 1, 2, and 6, the connecting member 100 includes a valve body structure 110 and a docking structure 120 connected together. A mounting cavity 1111 is disposed on the valve body structure 110, and an operating mechanism 300 is movably connected to the valve body structure 110. The docking structure 120 is located on the side facing the opening of the mounting cavity 1111, and the two sets of connecting members 10 are connected by interlocking through the docking structure 120. In this embodiment, by providing the docking structure 120 on the valve body structure 110, when the two sets of connecting members 10 are connected to each other, they can be locked together through the docking structure 120, thereby improving the connection strength between the two sets of connecting members 10.

[0206] Furthermore, the valve body structure 110 is provided with a seat 115, and the flow channel is provided inside the seat 115. The docking structure 120 is arranged around the seat 115. The connecting member 100 also includes a sealing gasket 130, which is provided on the seat 115 and is used to seal between the two seats 115 when the two sets of connecting members 10 are docked.

[0207] In this embodiment, the two sets of connecting parts 10 can be combined and connected by rotating with each other. By providing a sealing gasket 130 on the seat 115, when the two sets of connecting parts 10 are connected, the sealing gasket 130 can ensure the sealing between the seat 115, thereby effectively preventing leakage in the flow channel. It should be noted that the material of the sealing gasket 130 can be polytetrafluoroethylene (PTFE), rubber, or composite materials, etc.

[0208] In one embodiment, the sealing gasket 130 may be a C-type sealing gasket. The design of the C-type sealing gasket enables it to form an effective seal; its unique geometry allows it to self-expand under pressure, thereby better filling joint gaps. This structure ensures that the sealing gasket maintains a good seal during use, reducing the risk of leakage.

[0209] In one embodiment, the seat 115 has a mating sealing groove 1151, which is located on the outside of the seat 115, and the sealing gasket 130 is at least partially engaged in the mating sealing groove 1151.

[0210] This design allows the gasket 130 to provide excellent positioning during installation, facilitating assembly by operators. Simultaneously, because the gasket 130 is snapped into the mating sealing groove 1151, it maintains a stable position even under external pressure or other factors during use, thereby enhancing the strength of the sealing connection and reducing the risk of leakage due to displacement. Specifically, the shape and size of the sealing groove 1151 can be adjusted according to different gaskets 130 to adapt to various operating conditions and fluid types.

[0211] Furthermore, the connecting member 100 also includes a sealing sleeve 140, which is sleeved on the outside of the valve body structure 110 and is used to seal between the two valve body structures 110 when the two sets of connecting members 10 are mated.

[0212] With this configuration, when the two sets of connectors 10 are connected, the sealing sleeve 140 can effectively seal the outside of the connector 10, thereby achieving the dustproof function of the connector 10, preventing external particles and contaminants from entering the internal structure, and reducing potential damage to the limiting component 200.

[0213] It should be noted that the material of the sealing sleeve 140 can be a wear-resistant and high-temperature-resistant rubber or polymer material, such as fluororubber or silicone rubber, which have excellent performance in dust prevention and sealing. At the same time, the shape of the sealing sleeve 140 can be circular or rectangular to adapt to different valve body structures 110. The specific design should be flexibly adjusted according to the actual use conditions.

[0214] In some embodiments, the sealing sleeve 140 can also be designed with a multi-layered isolation structure, which significantly improves its dustproof and waterproof capabilities. Specifically, the sealing sleeve 140 can be composed of one or more layers of different materials, for example, the inner layer can be made of a highly elastic material to enhance sealing performance, while the outer layer can be made of a wear-resistant material to improve durability. The number of sealing sleeves 140 can also be one or more, and is not limited to a single one. Such a design can effectively meet the needs of different environmental conditions and improve the reliability and performance of the seal.

[0215] Specifically, the docking structure 120 includes a clearance groove 123, a locking groove 124, and multiple snap fasteners. The multiple snap fasteners are spaced apart along the circumferential direction of the opening of the flow channel, and at least one of the snap fasteners is spaced apart from the valve body structure 110 to form the locking groove 124, and the clearance groove 123 is connected to the locking groove 124. When the two sets of connecting parts 10 are docked, at least one of the snap fasteners is accommodated in the clearance groove 123 and moves into the locking groove 124 when the two sets of connecting parts 10 rotate relative to each other.

[0216] Therefore, when the two sets of connectors 10 are mated, the latch of one set of connectors 10 is first aligned with the clearance groove 123 of the other set of connectors 10. During connection, the latch is accommodated in the clearance groove 123 for positioning. Subsequently, by driving the two sets of connectors 10 to rotate relative to each other, the latch can smoothly move into the locking groove 124 of the other set of connectors 10, thereby completing the locking between the two sets of connectors 10.

[0217] Once the two sets of connecting components 100 are in place, the limiting component 200 can be operated by the operating mechanism 300 to limit the relative rotation of the two sets of connecting components 10, thereby completing the combined sealing of the two sets of connecting components 10.

[0218] In one embodiment, the latch includes a first latch 121 and a second latch 122. The first latch 121 surrounds the opening of the flow channel and protrudes outward. The second latch 122 is located outside the first latch 121, and the end face of the second latch 122 is flush with the plane of the opening of the mounting cavity 1111. The second latch 122 and the valve body structure 110 are spaced apart to form a locking groove 124, and a clearance groove 123 is provided on one side of the second latch 122 along the circumferential direction of the flow channel. When the two sets of connecting members 10 are connected, the first latch 121 of one set of connecting members 10 engages with the second latch 122 of the other set of connecting members 10.

[0219] In this embodiment, by forming an avoidance groove 123 on the edge of the second buckle 122, the first buckle 121 of the other set of connecting members 10 can be aligned with the avoidance groove 123. At this time, by rotating the connecting member 10, the first buckle 121 is engaged in the locking groove 124 located on the other side of the second buckle 122. This makes the combined structure of the two sets of connecting members 10 more compact and makes the surface of the connecting member 100 on the connecting surface 1114 more flat.

[0220] The embodiments of this disclosure are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The chassis body 100' for a server according to an embodiment of this disclosure is described below with reference to Figures 13-18, including: body 10'.

[0221] Specifically, as shown in Figures 13-21, the main body 10' is provided with multiple mounting positions 13, and the main body 10' is adapted to match different functional modules 20 through the multiple mounting positions 13.

[0222] Referring to Figures 13-17, multiple mounting positions 13 are distributed at different locations on the main body 10'. These multiple mounting positions 13 are suitable for matching functional modules 20 of different sizes and types, making it convenient for users to flexibly assemble multiple different functional modules 20 within the main body 100' of the chassis, thereby improving the flexibility of server configuration.

[0223] According to the embodiments of the present disclosure, the server chassis 100' has multiple mounting positions 13 suitable for installing functional modules 20 within it. This allows users to configure multiple functional modules 20 within the chassis 100' as needed. The multiple mounting positions 13, which are matched with different functional modules 20, are suitable for meeting various configuration requirements, thereby improving the reusability of the chassis 100' and reducing the development and production costs of the chassis 100' suitable for servers with different needs.

[0224] According to some embodiments of this disclosure, as shown in Figures 13-18, the functional module 20 is detachably connected to a plurality of mounting positions 13. The detachable connection between the functional module 20 and the mounting positions 13 facilitates the installation and removal of the functional module 20. This installation and removal can be completed without tools, simplifying the server assembly process and facilitating server maintenance and upgrades.

[0225] According to some embodiments of this disclosure, as shown in Figures 13-18, the same mounting position 13 is suitable for mounting functional modules 20 with the same height but different functions.

[0226] Users can configure, select, and install different functional modules 20 in the same chassis as needed to meet specific application scenarios or performance requirements.

[0227] Therefore, the same mounting position 13 can be used to install functional modules 20 with the same height but different functions, which can effectively enhance the practicality of the chassis body 100'. The chassis body 100' with a single structure can serve a variety of configuration needs, reducing the need to redesign or manufacture a new chassis due to changes in needs, thereby reducing the development and production costs of the chassis body 100'.

[0228] According to some embodiments of this disclosure, as shown in Figures 13-18, there are multiple functional modules 20, each with a different height, and each functional module 20 with a different height can be selectively connected to multiple mounting positions 13 respectively.

[0229] There are multiple mounting positions 13, which are suitable for being spaced apart along the height direction A on the mounting plate. The mounting positions 13 are adapted to functional modules 20 of different heights. A functional module 20 is suitable for assembly with two mounting positions 13 located at the same height. There can be multiple mounting positions 13, which are spaced apart along the height direction A. The functional module 20 can cooperate with mounting positions 13 of different heights to achieve the assembly of the functional module 20 at different height positions within the chassis body 100'.

[0230] Therefore, by providing multiple mounting positions 13 of different heights within the chassis body 100', users can easily assemble multiple functional modules 20 of different heights within the chassis body 100' as needed, which is suitable for meeting various configuration requirements.

[0231] According to some embodiments of this disclosure, as shown in Figures 14-17, the plurality of functional modules 20 include at least a first functional module and a second functional module, the first functional module and the second functional module having different heights, and the plurality of mounting positions 13 including at least one first mounting position 14 and at least one second mounting position 15, the first mounting position 14 being adapted to mount the first functional module; the second mounting position 15 being adapted to mount the second functional module.

[0232] The first mounting position 14 and the second mounting position 15 are located on the inner side wall of the main body 10'. The first mounting position 14 and the second mounting position 15 are spaced apart along the height direction A of the main body 10' to ensure that each mounting position 13 can make reasonable use of the space inside the chassis and avoid interference between functional modules 20 of different heights.

[0233] Therefore, the first and second functional modules have different heights. Users can mix and install functional modules 20 of different heights within the same chassis body 100' as needed to optimize hardware configuration. By rationally arranging the mounting positions 13 of different heights, the internal space of the chassis body 100' can be effectively utilized, thereby accommodating more hardware devices and increasing the versatility and compatibility of the chassis body 100'. By setting at least one first mounting position 14 and at least one second mounting position 15, the flexibility and adaptability of the chassis body 100' can be improved, and the space utilization rate of the chassis body 100' can be increased.

[0234] According to some embodiments of this disclosure, as shown in Figures 14-18, two first mounting positions 14 are adapted to jointly mount a second functional module.

[0235] The first functional module and the second functional module have different heights, with the second functional module being taller than the first functional module. The first mounting position 14 can be used to install the first functional module, and two first mounting positions 14 can be used together to install the second functional module. The second mounting position 15 can be used to install the second functional module, and it can also be used to install two first functional modules. The second mounting position 15 can be composed of two adjacent first mounting positions 14.

[0236] Therefore, mounting positions 13 of different heights can be used to install functional modules 20 of corresponding heights, and mounting positions 13 of the same height can be combined to install functional modules 20 of higher heights, effectively improving the applicability of mounting positions 13, meeting various configuration requirements, and enhancing the reusability of the chassis body 100'.

[0237] According to some embodiments of this disclosure, as shown in Figures 14-18, the first mounting position 14 and the second mounting position 15 are adapted to jointly mount at least one functional module 20.

[0238] The multiple functional modules 20 also include a third functional module. The third functional module, the second functional module and the first functional module have different heights. Taking the first functional module, the second functional module and the third functional module as examples where the heights increase sequentially, in some embodiments, the first mounting position 14 and the second mounting position 15 can be used together to install the third functional module, or the three first mounting positions 13 can be used together to install the third functional module, and so on.

[0239] Therefore, the first mounting position 14 and the second mounting position 15 are suitable for combined use to install functional modules 20 with higher heights. That is, multiple mounting positions 13 of different heights can be combined, which can further improve the applicability of the mounting positions 13, adapt to functional modules 20 of various heights, and effectively improve the versatility and compatibility of the chassis body 100'.

[0240] According to some embodiments of this disclosure, as shown in Figures 14-18, the first mounting position 14 and the second mounting position 15 are offset along the length direction B of the body 10'.

[0241] That is, along the length direction B of the chassis body 100', the first mounting position 14 and the second mounting position 15 are arranged alternately, instead of being aligned vertically along the height direction A of the chassis body 100'.

[0242] Therefore, the staggered arrangement of the first mounting position 14 and the second mounting position 15 can reduce physical interference between different functional modules 20 and avoid interference during the assembly of different functional modules 20. By reasonably arranging the layout of the first mounting position 14 and the second mounting position 15, the internal space of the chassis body 100' can be utilized to the maximum extent, and a more reasonable hardware configuration can be achieved.

[0243] According to some embodiments of this disclosure, the height of the first mounting position 14 along the height direction A of the body 10' is greater than the height of the second mounting position 15 along the height direction A of the body 10'.

[0244] In some embodiments, the first mounting position 14 is adapted to mount a functional module 20 with a higher height, and the second mounting position 15 is adapted to mount a functional module 20 with a lower height; alternatively, the first mounting position 14 and the second mounting position 15 can be used to jointly mount a functional module 20 with a higher height. The first mounting position 14 is located above the second mounting position 15 along the height direction A of the body 10'.

[0245] Therefore, users can select different heights of mounting positions 13 according to their actual needs, and install functional modules 20 of different heights and functions, thereby improving the adaptability and expandability of the chassis body 100'. By reasonably setting different heights of mounting positions 13, the internal space of the chassis body 100' can be utilized more effectively, avoiding space waste. When it is necessary to replace or add functional modules 20, users can easily find a suitable mounting position 13, simplifying the maintenance and upgrade process.

[0246] According to some embodiments of this disclosure, there are multiple first mounting positions 14, and the multiple first mounting positions 14 are respectively located at both ends of the length direction B of the body 10'; and / or, there are multiple second mounting positions 15, and the multiple second mounting positions 15 are respectively located at both ends of the length direction B of the body 10'.

[0247] The main body 10' has a plurality of first mounting positions 14, which are located at both ends of the main body 10' along the length direction B; or, the main body 10' has a plurality of second mounting positions 15, which are located at both ends of the main body 10' along the length direction B; or, the main body 10' has a plurality of first mounting positions 14 and a plurality of second mounting positions 15, which are located at both ends of the main body 10' along the length direction B.

[0248] Therefore, by distributing the mounting positions 13 at both ends of the chassis body 100', the layout at both ends can maximize the use of the internal space of the chassis body 100', especially in the length direction B, where the equipment can be distributed more evenly and space waste can be reduced. Multiple first mounting positions 14 and multiple second mounting positions 15 can be configured simultaneously, or only one type of multiple mounting positions 13 can be selected. This flexibility allows the chassis body 100' to adapt to various configuration requirements.

[0249] According to some embodiments of this disclosure, as shown in FIG15, the body 10' includes: a housing 11 and at least one mounting plate 12, the mounting plate 12 being disposed on the inner side wall of the housing 11, and the mounting plate 12 having at least one mounting position 13.

[0250] The enclosure 11 serves as the frame for the main body 100', providing overall support for the main body 100' and protecting the electronic equipment inside the enclosure 10' from external environmental influences. The mounting plate 12 is fixed to the inner wall of the enclosure 11, and has multiple mounting positions 13 for mounting the functional modules 20. The mounting plate 12, fixed to the inner wall of the enclosure 11, provides a stable support structure, ensuring the assembly stability of the functional modules 20. The mounting positions 13 on the mounting plate 12 are suitable for assembling with the functional modules 20. The separation of the mounting plate 12 from the enclosure 11 facilitates the design and manufacture of different mounting positions 13. The mounting plate 12 can be designed and manufactured independently of the enclosure 11. Different mounting positions 13 can be customized according to actual needs, supporting functional modules 20 of different heights and sizes, making the configuration more flexible and reducing the overall development cost of the main body 100'.

[0251] According to some embodiments of this disclosure, as shown in FIG15, the mounting plate 12 and the housing 11 are integrally formed; or, at least a portion of the housing 11 is formed as the mounting plate 12.

[0252] In some embodiments, the mounting plate 12 and the housing 11 are an integral structure. This one-piece design significantly improves the overall structural strength of the mounting plate 12 and housing 11, reduces weaknesses caused by connection points, and makes the mounting plate 12 and housing 11 more durable. One-piece molding reduces the number of parts, simplifies assembly steps, lowers production costs, and may improve production efficiency.

[0253] According to some embodiments of the present disclosure, as shown in FIG15, at least one opening is formed on the mounting plate 12, the mounting position 13 is connected to the side wall of the opening, the mounting position 13 is located on the side of the opening away from the inner side wall of the housing 11 and is spaced apart from the inner side wall of the housing 11, and a mounting groove 16 is formed on the mounting position 13, the mounting groove 16 penetrates the mounting plate 12 along the thickness direction of the mounting plate 12.

[0254] Mounting position 13 is formed by at least a portion of mounting plate 12 protruding towards the center of the main body of housing 11 along the thickness direction of mounting plate 12. Mounting position 13 maintains a certain distance from the inner side wall of housing 11. Mounting groove 16 is adapted to be opposite to the opening of mounting plate 12. Mounting groove 16 is provided through mounting plate 12 along the thickness direction of mounting plate 12, which facilitates the direct insertion of functional module 20 into mounting groove 16 through the opening to assemble with mounting position 13, and facilitates the quick installation and removal of functional module 20.

[0255] Therefore, the connection between the mounting position 13 and the side wall of the opening increases the structural strength of the mounting plate 12, preventing deformation or damage during long-term use. The design of the mounting groove 16 allows the functional module 20 to be directly inserted into the mounting plate 12 without additional tools, simplifying the installation and disassembly process. The mounting position 13 maintains a certain distance from the inner side wall of the housing 11, providing sufficient space for the assembly of the functional module 20 and the mounting position 13, avoiding interference with other equipment or the walls of the housing 11.

[0256] According to some embodiments of this disclosure, as shown in FIG15, the mounting groove 16 includes a guide groove segment 161 and a mating groove segment 162. The guide groove segment 161 extends along the height direction A of the body 10', and one end of the guide groove segment 161 passes through the mounting position 13. One end of the mating groove segment 162 is connected to the other end of the guide groove segment 161, and the other end of the mating groove segment 162 extends along the length direction B of the body 10'.

[0257] The guide groove 161 extends along the height direction A of the body 10', guiding the functional module 20 to move a certain distance in the height direction A. The mating groove 162 extends along the length direction B of the body 10', guiding the functional module 20 to move a certain distance in the length direction B. The guide groove 161 and the mating groove 162 connect to form an L-shaped mounting groove 16. When assembling the functional module 20 with the mounting groove 16, the functional module 20 is first inserted into the guide groove 161 perpendicular to the thickness direction of the mounting plate 12, moves along the height direction A within the guide groove 161 to the other end of the guide groove 161, and then moves along the length direction B within the mating groove 162 from one end of the mating groove 162 to the other end of the mating groove 162, completing the positioning.

[0258] Therefore, the guide groove 161 is suitable for guiding the functional module 20 to move in the height direction A, and the mating groove 162 is suitable for guiding the functional module 20 to move in the length direction B and limiting the functional module 20 in the height direction A. The installation groove 16, including the guide groove 161 and the mating groove 162, can ensure that the functional module 20 moves along a predetermined path during installation, reducing installation errors. The L-shaped structural design can simplify the installation steps, eliminating the need for complex assembly processes. It can also ensure that the functional module 20 is firmly fixed in the correct position after installation, preventing loosening or falling off, and improving the accuracy and stability of the functional module 20 device.

[0259] According to some embodiments of this disclosure, as shown in FIG15, the width of the guide groove 161 gradually decreases at least at the end away from the mating groove 162 along the end of the guide groove 161 toward the mating groove 162.

[0260] The guide groove segment 161 extends along the height direction A of the body 10'. One end of the guide groove segment 161 communicates with the mating groove segment 162, and the other end of the guide groove segment 161 extends along the height direction A of the body 10' in a direction away from the mating groove segment 162. The width of the other end of the guide groove segment 161 is greater than the width of the end of the guide groove segment 161 that communicates with the mating groove segment 162. The functional module 20 is assembled into the guide groove segment 161 from the other end of the guide groove segment 161, and then moves along the extension direction of the guide groove segment 161 from the wider end of the guide groove segment 161 to the narrower end where the guide groove segment 161 communicates with the mating groove segment 162.

[0261] Therefore, the wider end of the guide groove 161 makes it easier for the functional module 20 to be inserted vertically into the guide groove 161, reducing resistance during insertion and avoiding installation difficulties caused by alignment problems. As the functional module 20 moves along the guide groove 161, the width of the guide groove 161 gradually decreases, which better guides the functional module 20 to move along the correct path. The gradually decreasing width of the guide groove 161 ensures that the functional module 20 gradually stabilizes during installation, reducing the risk of shaking or deviation during installation.

[0262] According to some embodiments of this disclosure, as shown in FIG15, the width of the mating groove 162 gradually decreases along the direction from one end of the mating groove 162 toward the other end of the mating groove 162.

[0263] Functional module 20 enters the mating groove section 162 along the length direction B, and continues to slide from one end of the mating groove section 162 to the other end of the mating groove section 162 along the extension direction of the mating groove section 162, completing the final positioning.

[0264] Therefore, the gradually decreasing width of the mating groove 162 ensures that the functional module 20 gradually stabilizes during installation, reducing the risk of shaking or deviation during installation, improving the stability and reliability of the assembly between the mating groove 162 and the functional module 20, ensuring that the functional module 20 has good guidance and support throughout the installation process, and improving the accuracy and reliability of installation.

[0265] According to some embodiments of this disclosure, as shown in FIG14, the housing 11 includes: a bottom plate 111' and two side plates 112', the two side plates 112' are respectively disposed on both sides of the width direction C of the bottom plate 111', a plurality of mounting positions 13 are respectively disposed on the two side plates 112', the two side plates 112' and the bottom plate 111' together define an accommodating space, and the functional module 20 is adapted to be disposed in the accommodating space.

[0266] The base plate 111' forms the foundation of the enclosure 11, providing a horizontal support surface. Side plates 112' are respectively positioned on both sides of the base plate 111' in the width direction C, forming the basic frame of the enclosure 11 together. The base plate 111' and the two side plates 112' collectively define an accommodating space for installing and accommodating the functional modules 20. Mounting positions 13 are respectively provided on the two side plates 112' for fixing functional modules 20 at different heights.

[0267] Therefore, the frame structure composed of the base plate 111' and the two side plates 112' provides good mechanical stability, ensuring that the chassis body 100' will not deform or become unstable when multiple functional modules 20 are installed. By setting the mounting position 13 on the side plate 112', the space of the chassis body 100' can be fully utilized, allowing the functional modules 20 to be installed vertically, thus improving space utilization.

[0268] Specifically, as shown in Figures 15 and 16, a mounting groove 16 is formed on the first mounting position 14, and two mounting parts 21 are formed on the two side walls of the first functional module along the width direction C. Two first mounting positions 14 are formed on the two side plates 112' of the housing 11. The mounting parts 21 on the two side walls of the first functional module correspond to and cooperate with the mounting grooves 16 of the first mounting positions 14 on the two side plates 112', so that the installation of the first functional module can be realized. Two mounting slots 16 are formed on the second mounting position 15. The two mounting slots 16 are spaced apart along the height direction A and staggered along the length direction B. At least two mounting parts 21 are formed on the two side walls of the second functional module along the width direction C. Two second mounting positions 15 are formed on the two side plates 112' of the housing 11. The two second mounting positions 15 are spaced apart along the length direction B on the side plates 112'. The at least two mounting parts 21 on the two side walls of the second functional module correspond to and cooperate with the mounting slots 16 of the second mounting positions 15 on the two side plates 112', so that the installation of the second functional module can be realized.

[0269] In some embodiments, the two mounting slots 16 of the second mounting position 15 can respectively cooperate with two first functional modules. That is, a mounting portion 21 on one side wall of one first functional module cooperates with one mounting slot 16 of the second mounting position 15, and a mounting portion 21 on one side wall of the other first functional module cooperates with the other mounting slot 16 of the second mounting position 15, and so on on the other side. Alternatively, two first mounting positions 14 can jointly mount a second functional module. The two first mounting positions 14 are sequentially arranged on the side plate 112' along the height direction A. At least two mounting portions 21 are formed on one side wall of the second functional module. One mounting portion 21 cooperates with the mounting slot 16 of one first mounting position 14, and the other mounting portion 21 cooperates with the mounting slot 16 of the other first mounting position 14, and so on on the other side. By analogy, the first mounting position and the second mounting position can jointly mount a third functional module, or the three first mounting positions can jointly mount a third functional module.

[0270] According to some embodiments of this disclosure, as shown in FIG13, the main body 10' further includes: a motherboard module, a debugging module, a power supply module, and a heat exchange module, wherein the motherboard module is disposed within the receiving space; the debugging module is disposed within the receiving space; the power supply module is disposed within the receiving space; and the heat exchange module is disposed within the receiving space.

[0271] According to some embodiments of this disclosure, as shown in FIG13, the motherboard module, debugging module, power supply module and heat exchange module are all located in the middle of the body 10' along the length direction B within the accommodating space, and the functional modules 20 are adapted to be respectively located on both sides of the motherboard module, debugging module, power supply module and heat exchange module along the length direction B of the body 10'.

[0272] The motherboard module, debugging module, power supply module, and heat exchange module are electrically connected to the functional modules. The motherboard module is responsible for processing data and coordinating the work of each functional module 20. The debugging module is used to monitor and debug the server's operating status to ensure normal system operation. The power supply module is responsible for providing a stable power supply to the server, and the heat exchange module is used for heat dissipation to ensure that the internal temperature of the server is within a safe range. The motherboard module, debugging module, power supply module, and heat exchange module are located in the middle of the housing space, which facilitates electrical connection with the functional modules on both sides, facilitates centralized management and maintenance, and reduces the workload of maintenance personnel. Distributing the functional modules 20 on both sides of the core module can balance the weight distribution inside the chassis and avoid structural instability caused by excessive weight on one side. The functional modules 20 can be flexibly configured on both sides according to actual needs, which facilitates upgrades and expansions.

[0273] Therefore, by concentrating the motherboard module, debugging module, power supply module, and heat exchange module in the middle of the chassis body 100' along the length direction B, and placing the functional modules 20 on both sides of these modules, this design can achieve more reasonable and balanced space utilization, which is conducive to the miniaturization design of the chassis body 100' and improves the integration of the server.

[0274] According to some embodiments of this disclosure, as shown in Figures 14 and 15, a plurality of fixing holes 17 are formed on the body 10'.

[0275] The fixing hole 17 can be a screw hole, which is suitable for mating with fasteners. After the functional module 20 is assembled in the mounting slot 16 and moved into place, the functional module 20 can be further assembled on the inner side wall of the body 10' of the chassis body 100' by the mating of the fasteners and the fixing hole 17.

[0276] Therefore, multiple fixing holes 17 are formed on the main body 10' to facilitate the engagement with fasteners, further strengthening the fixation of the functional module 20 within the chassis main body 100' and preventing it from loosening or shifting due to vibration or other reasons during use. The use of fasteners ensures the stability of the functional module 20 during long-term operation, reducing malfunctions or performance degradation caused by loosening. Fixing the functional module 20 with fasteners simplifies the maintenance and replacement process; disassembly and installation can be completed simply by loosening or tightening the fasteners.

[0277] According to some embodiments of this disclosure, as shown in Figures 14 and 15, the fixing hole 17 is disposed adjacent to the mounting position 13.

[0278] By positioning the mounting holes 17 adjacent to the mounting positions 13, the functional module 20 can be secured more effectively, ensuring its stability and reliability. The fasteners, engaging with the mounting holes 17 adjacent to the mounting positions 13, ensure that the functional module 20 is more firmly fixed to the chassis body 100' after installation, preventing loosening or displacement due to vibration or other reasons. Positioning the mounting holes 17 adjacent to the mounting positions 13 optimizes space utilization, reduces unnecessary space waste, and allows for a more compact internal chassis layout.

[0279] A server chassis according to a second aspect embodiment of the present disclosure, as shown in FIG13, includes: a chassis body 100' and at least one functional module 20. The chassis body 100' is the same as the server chassis body 100' according to the first aspect embodiment of the present disclosure described above. The functional module 20 is disposed on the chassis body 100' and is mounted on the chassis body 100' through a corresponding mounting position 13.

[0280] According to the embodiments of the present disclosure, in a server chassis, at least one functional module 20 is mounted on the chassis body 100' and fixed by a matching mounting position 13 on the chassis body 100', achieving more compact space utilization and higher structural stability. This makes the server chassis not only more flexible in hardware configuration but also more convenient in management and maintenance, thereby improving the overall reliability and user experience of the chassis used for server systems.

[0281] According to some embodiments of this disclosure, as shown in Figures 14 and 16, the functional module 20 is provided with a mounting part 21, which cooperates with the mounting position 13 to install the functional module 20 on the chassis body 100'.

[0282] One end of the mounting part 21 is connected to the surface of the functional module 20 opposite to the side plate 112'. The other end of the mounting part 21 extends toward the side plate 112' and is adapted to be inserted into the mounting groove 16. The functional module 20 is installed and fixed by moving the mounting part 21 within the mounting groove 16. The mounting part 21 includes a mounting post and a protrusion. One end of the mounting post is connected to one side surface of the functional module 20, and the other end of the mounting post extends toward the side plate 112'. The other end of the mounting post has a protrusion with a cross-sectional area larger than that of the mounting post. The protrusion of the mounting part 21 is fitted into the mounting groove 16 by the wider end of the guide groove section 161. The larger cross-sectional area of ​​the protrusion ensures the stability of the fit between the mounting part 21 and the mounting groove 16, preventing the mounting part 21 from falling out of the mounting groove 16.

[0283] Therefore, the installation part 21 facilitates the assembly of the functional module 20. When the functional module 20 needs to be replaced or repaired, it can be quickly disassembled through a simple reverse operation, which simplifies the installation and disassembly process, realizes the cooperation and disassembly between the functional module 20 and the installation position 13, and improves the stability and reliability of the cooperation between the functional module 20 and the installation position 13.

[0284] According to some embodiments of this disclosure, as shown in Figures 14 and 16, the mounting part 21 is installed in the mating groove 162 after it mates with the guide groove section 161 of the mounting position 13.

[0285] That is, the protrusion of the mounting part 21 is first inserted into the guide groove 161 from the wider end of the guide groove 16, perpendicular to the thickness direction of the mounting plate 12. Then, it moves along the height direction A within the guide groove 161 to the other end of the guide groove 161. Finally, it moves along the length direction B within the mating groove 162 from one end of the mating groove 162 to the other end of the mating groove 162, thus completing the positioning.

[0286] Therefore, the design of the mounting part 21 allows the functional module 20 to be initially positioned by simple insertion and sliding actions. By moving the mounting part 21 within the mounting slot 16, the functional module 20 is installed and fixed, improving the stability and reliability of the cooperation between the functional module 20 and the mounting position 13.

[0287] According to some embodiments of this disclosure, as shown in Figures 14 and 16, there are multiple mounting portions 21, and the functional module 20 is provided with multiple mounting holes b18. At least two mounting portions 21 can selectively cooperate with at least two mounting holes b18, and the mounting portions 21 are adapted to cooperate with the mounting grooves 16 of the corresponding mounting positions 13.

[0288] In some embodiments, the functional module 20 may have a plurality of mounting holes b18 formed on both side walls along the width direction C of the body 10'. A portion of the plurality of mounting parts 21 is adapted to mate with a portion of the plurality of mounting holes b18, and the mounting holes b18 may be formed as hole-like structures adapted to the mounting parts 21. For example, referring to FIG. 20, the plurality of mounting holes b18 may be spaced apart along the height direction A and the length direction B. At least two mounting parts 21 may selectively mate with at least two mounting holes b18. The mounting parts 21 may be riveted to the mounting holes b18, and one end of the mounting part 21 assembled in the mounting hole b18, away from the functional module 20, protrudes from the side wall of the functional module 20 along the width direction C. Thus, the aforementioned end of the mounting part 21 away from the functional module 20 corresponds to the mounting position 13 on the side plate 112' of the body 10', thereby achieving reliable installation of the functional module 20 within the chassis body 100'. The mounting part 21 can selectively mate with mounting holes b18 located at different positions, and then mate with the mounting slots 16 of the corresponding mounting positions 13 on the side plate 112' of the enclosure 11. That is, the position of the functional module 20 relative to the main body 10' can be adjusted by adjusting the position of the mounting part 21. In some specific examples, two second functional modules and one first functional module are installed in the main body 100' of the enclosure. When installing one of the second functional modules, referring to Figure 20, six mounting holes b18 can be formed on each of the two side walls along the width direction C of the main body 10'. Four mounting parts 21 can be provided on one side of the second functional module. These four mounting parts 21 can mate with the four outer mounting holes b18 of the six mounting holes b18. Then, the second functional module with eight mounting parts 21 is mated with the four corresponding mounting slots 16 of the second mounting positions 15 on the side plate 112' of the enclosure 11, thereby realizing the installation of the second functional module. Optionally, the second functional module can be mounted on the upper front side of the main body 10'. The chassis body 100' for the server further includes a fastener that, when the mounting portion 21 on the functional module 20 moves into place in the mounting slot 16, passes through the side wall of the functional module 20 and connects to the chassis body 100' to secure the functional module 20 to the enclosure 11.

[0289] When installing another second functional module, referring to Figure 21, the second functional module has two mounting parts 21 on one side. These two mounting parts 21 can be adapted to the two inner mounting holes b18 among the six mounting holes b18. Then, the two mounting parts 21 are engaged with the corresponding mounting slots 16 of the corresponding mounting positions 13 on the side plate 112', thereby realizing the installation of the second functional module. The two mounting parts 21 engage with two of the corresponding mounting slots 16 of the two second mounting positions 15 on the side plate 112' of the housing 11, or with the two mounting slots 16 of the two first mounting positions 14 on the side plate 112'. Optionally, the aforementioned second functional module can be installed on the lower rear side of the main body 10'.

[0290] When installing the first functional module, referring to Figure 19, four mounting holes b18 can be formed on each of the two side walls along the width direction C of the body 10'. For each side wall along the width direction C of the body 10', two mounting parts 21 are fitted into two of the four mounting holes b18. Then, the first functional module with the four mounting parts 21 can be fitted into the four mounting slots 16 of the corresponding first mounting position 14 on the side plate 112' of the housing 11, or the two mounting parts 21 can be fitted into two of the corresponding mounting slots 16 on the second mounting position 15 to install the first functional module in the first mounting position 14 or the second mounting position 15. Optionally, the first functional module can be installed on the upper rear side of the body 10'.

[0291] In practical applications, the installation sequence of functional modules 20 can be adjusted according to the actual situation to improve the assembly flexibility and practicality of the chassis body 100'.

[0292] The assembly process of functional module 20 is as follows: Align the mounting part 21 of functional module 20 with the mounting groove 16 on the inner wall of the side plate 112' of the enclosure 11, and insert it downwards into the enclosure 11 along the height direction A, so that the protrusion of the mounting part 21 is inserted into the mounting groove 16. After it is lowered to the bottom, push the functional module 20 forward or backward to the bottom along the length direction B to complete the assembly of functional module 20 with mounting position 13. Then, pass the fastener through the side wall of functional module 20 and connect it to the side wall of the body 10' to assemble functional module 20 onto the inner side wall of the body 10' of the enclosure body 100', thus completing the assembly of functional module 20.

[0293] When disassembling the functional module 20, first unplug the chassis cable, then remove the fasteners, push the functional module 20 backward or forward to the end along the length direction B, and then lift the functional module 20 upward from the chassis 11 along the height direction A. This will separate the functional module 20 from the chassis 11 and complete the quick tool-free disassembly of the functional module 20.

[0294] Similarly, the installation and removal method of the third functional module is the same as that of the first and second functional modules. Multiple mounting holes b18 can be formed on both side walls of the third functional module along the width direction C of the body 10'. Multiple mounting parts 21 can mate with some of the mounting holes b18. Several mounting parts 21 on one side wall of the third functional module mate with the corresponding mounting grooves 16 of the second mounting positions 15 on the side plate 112' of the housing 11. Several mounting parts 21 also mate with the corresponding mounting grooves 16 of the first mounting positions 14 on the side plate 112' of the housing 11.

[0295] Thus, multiple mounting holes b18 are distributed at different positions on the functional module 20, and multiple mounting positions 13 are correspondingly distributed at different positions on the chassis body 100'. The mounting parts 21 mate with different mounting holes b18 and corresponding mounting slots 16, allowing the functional module 20 to be quickly and easily installed onto the chassis body 100'. At least two mounting parts 21 can selectively mate with at least two mounting holes b18 and with corresponding mounting slots 16 of corresponding mounting positions 13, enabling the functional module 20 to select different installation positions according to actual needs, improving system flexibility and meeting diverse installation requirements. The cooperation of multiple mounting parts 21 with multiple mounting holes b18 provides multi-point fixation, ensuring stable fixation of the functional module 20 and reducing the risk of loosening or detachment.

[0296] According to some embodiments of the present disclosure, as shown in FIG14, the chassis body 100' for a server further includes: a fastener, the fastener passing through the functional module 20 and connected to the chassis body 100'.

[0297] The fastener passes through the side wall opposite to the functional module 20 and engages with the fixing hole 17 on the chassis body 100'. After the mounting part 21 on the functional module 20 moves into place in the mounting groove 16, the fastener engages with the fixing hole 17 to complete the fixing process of the chassis body 100'.

[0298] Therefore, by using fasteners to engage the mounting part 21 with the fixing holes 17 on the chassis body 100', the functional module 20 can be securely fixed on the chassis body 100', preventing loosening or displacement. The functional module 20 can be easily disassembled and replaced using fasteners, facilitating daily maintenance and upgrades.

[0299] According to some embodiments of this disclosure, as shown in FIG14, the fastener is a hand-operated screw.

[0300] The hand-operated screws are designed to be tightened or loosened by hand, eliminating the need for screwdrivers or other tools. This hand-operated design makes the installation and removal of the functional module 20 extremely simple; users can tighten or loosen it by hand without tools, making maintenance and replacement of the functional module 20 faster and more convenient.

[0301] According to some embodiments of this disclosure, as shown in FIG13, there are multiple functional modules 20, which are independent of each other. That is, each functional module 20 can be installed, disassembled and operated independently without affecting each other; and / or, the multiple functional modules 20 communicate with the motherboard module of the chassis body 100' respectively, and each functional module 20 has an independent communication path connected to the motherboard module; and / or, the multiple functional modules 20 can communicate with each other, and communication connections can also be established between the multiple functional modules 20, allowing the functional modules 20 to directly exchange data or work collaboratively.

[0302] Therefore, multiple independent functional modules 20 can be flexibly configured as needed, and users can choose different combinations of functions according to their actual needs. Since the functional modules 20 are independent of each other, they can be disassembled and replaced individually, simplifying the maintenance and upgrade process. Each functional module 20 communicates separately with the motherboard module, ensuring efficient and reliable data transmission. The design of multiple functional modules 20 allows the system to be expanded as needed, increasing the scalability and adaptability of the server.

[0303] A server according to a third aspect of the present disclosure includes a server chassis body 100' according to the first aspect of the present disclosure described above, or a server chassis according to the second aspect of the present disclosure described above.

[0304] According to the server of the present disclosure, by applying the chassis body 100' or the chassis for the server in the above embodiments, the design of the chassis body 100' ensures the overall structural stability of the server. The functional module 20 cooperates with the mounting position 13 through the mounting part 21, and the installation process is simple and quick. The functional module 20 can be easily disassembled and replaced, which is convenient for daily maintenance and upgrades. The design of the mounting position 13 enables the functional module 20 to make efficient use of the internal space of the chassis, thereby improving the overall reliability and space utilization of the server.

[0305] Server expansion modules are computer hardware or software used to expand system functionality to meet different user needs. When the expansion module is hardware, it can be fixed to the server chassis via a base and connected to the server's motherboard via a connector. For example, as an example, for a GPU server expansion module, a RISER card is used as the connector, and a RISER mounting bracket and a mounting base are provided. During installation, the RISER card is first fixed to the RISER card mounting bracket with screws. Then, the expansion module is connected to the RISER card and fixed to the RISER card mounting bracket with screws. Next, it is placed in the mounting base and fixed with screws to form the expansion module. Finally, the entire expansion module is placed into the chassis and fixed, allowing the RISER card to connect to the piping or slots in the chassis. Therefore, in related technologies, the assembly steps of expansion modules generally require 3 to 4 steps and require tools (such as screwdrivers or automatic screwdrivers) for fixing, which is cumbersome, time-consuming, inefficient, and costly in terms of production.

[0306] In view of this, in one respect, the present disclosure provides a fixing device for simplifying assembly operations and steps, improving assembly efficiency, and reducing production costs.

[0307] Please refer to Figure 22, which shows a schematic diagram of the structure of the fixing device 2002 provided in the embodiment of this disclosure. The fixing device 2002 includes a base 1, a connector 2, and a clamping mechanism 3.

[0308] Base 1 is a component used to connect to the server chassis 1000.

[0309] Connector 2 is a component used to plug into and mate with the expansion module. Connector 2 is fixed to the base 1, for example, it can be pre-fixed by anchors such as screws, or fixed by bonding, welding or other methods.

[0310] The clamping mechanism 3 is a component used to press the expansion module 2001 against the connector 2 and fix the expansion module 2001. The clamping mechanism 3 is rotatably connected to the base 1 and frictionally engages with the base 1. The clamping mechanism 3 has a clamping position and a releasing position. In the releasing position, the clamping mechanism 3 allows the insertion and removal path of the expansion module 2001. In the clamping position, the clamping mechanism 3 blocks the insertion and removal path of the expansion module 2001 and abuts against the side of the expansion module 2001 away from the connector 2, thereby clamping and fixing the expansion module 2001. Due to the frictional engagement between the clamping mechanism 3 and the base 1, the clamping mechanism 3 has a damping effect during rotation, which not only increases the operating feel during assembly but also allows the clamping mechanism 3 to remain in its current rotational position without external force. For example, when inserting or removing the expansion module 2001, the clamping mechanism 3 remains in the releasing position without manual support, making operation easier.

[0311] When assembling the expansion module 2001 onto the fixing device 2002 provided in this embodiment, assembly can begin once the clamping mechanism 3 is confirmed to be in the released position. The assembly process is shown in Figures 23, 24, and 25. First, the expansion module 2001 is inserted into the connector 2, and then the clamping mechanism 3 is rotated to the clamping position to complete the assembly. Thus, assembly can be completed simply by inserting the connector 2 and rotating the clamping mechanism 3, without the need for tools.

[0312] There are various ways to make friction between the base 1 and the clamping mechanism 3. For example, a shim can be provided between the clamping mechanism 3 and the base 1 so that the clamping mechanism 3 generates damping by rubbing against the shim when it rotates; or a damping rod can be provided between the base 1 and the clamping mechanism 3.

[0313] In some embodiments, as shown in Figures 26 and 27, the clamping mechanism 3 has an elastic arm 322", and the base 1 has a first surface 15. The elastic arm 322" is in frictional engagement with the first surface 15. By providing the elastic arm 322" on the clamping mechanism 3 in frictional engagement with the first surface 15 of the base 1, frictional damping is achieved when the clamping mechanism 3 rotates without adding additional components. Furthermore, the elasticity of the elastic arm 322" itself makes the clamping mechanism 3 less prone to jamming due to excessive friction, thus ensuring the flexibility of the clamping mechanism 3.

[0314] For example, as shown in Figures 26 and 27, the clamping mechanism 3 rotates relative to the base 1 about a first axis. The first surface 15 of the base 1 is perpendicular to the extension direction of the first axis. The elastic arm 322" is a cantilever structure with one end fixed and the other end extending towards the base 1. The free end of the elastic arm 322" abuts against the first surface 15. When the clamping mechanism 3 rotates, the free end of the elastic arm 322" moves on the first surface 15, thereby generating friction to form a damping effect.

[0315] It should be understood that the term "vertical" in the description of this disclosure does not mean that absolute verticality is required. For example, "the first surface 15 is perpendicular to the extension direction of the first axis" does not require that the first surface 15 is absolutely perpendicular to the first axis. The first surface 15 may have a certain angle of inclination relative to the first axis, as long as the elastic arm 322" can remain in contact with the first surface 15 during the rotation of the clamping mechanism 3.

[0316] In some embodiments, the first surface 15 is provided with a first positioning structure 151, and the elastic arm 322" is provided with a mating structure 3221. The mating structure 3221 and the first positioning structure 151 cooperate to position the clamping mechanism 3 in the clamping position. In addition to the positioning function, when the clamping mechanism 3 rotates to the point where the mating structure 3221 and the first positioning structure 151 are engaged, it also serves as a prompt to the operator to avoid excessive rotation of the clamping mechanism 3, which could cause excessive force on the expansion module 2001 and damage.

[0317] In some embodiments, the elastic arm 322" abuts against the first surface 15 via a mating structure 3221. That is, the mating structure 3221 is disposed on the side of the elastic arm 322" facing the first surface 15. The elastic arm 322" not only engages with the first positioning structure 151 via this mating structure 3221, but also abuts against the first surface 15 via the mating structure 3221, thereby simplifying the structure of the elastic arm 322". Furthermore, since the elastic arm 322" does not completely contact the first surface 15, the resulting frictional force is less likely to be excessive and cause jamming. In addition, the abutting force between the elastic arm 322" and the first surface 15 can be adjusted by setting the dimension of the mating structure 3221 along the first axis direction, thereby adjusting the magnitude of the frictional force.

[0318] As shown in Figures 26 and 27, the mating structure 3221 includes a protrusion formed on the elastic arm 322", while the first positioning structure 151 includes a groove formed on the first surface 15. The elastic arm 322" abuts against the first surface 15 through the protrusion. When the clamping mechanism 3 rotates, the protrusion moves along an arc-shaped path on the first surface 15. When the clamping mechanism 3 rotates to the clamping position, the protrusion is embedded in the groove to position the clamping mechanism 3 in the clamping position.

[0319] In some embodiments, as shown in FIG28, the surface of the protrusion is spherical, which facilitates the smooth entry and exit of the protrusion into or out of the groove and avoids jamming.

[0320] In some embodiments, the inner wall of the groove has a guide surface for guiding the protrusion into or out of the groove, the guide surface including a slope and / or a stepped surface. That is, by providing a slope, a stepped surface, or a combination of slope and stepped surfaces as a guide surface on the inner wall of the groove, the protrusion can smoothly enter or leave the groove, avoiding jamming.

[0321] Referring again to Figure 28, in some embodiments, the inner wall of the groove includes a bottom surface 1511, a first inclined surface 1512, and a second inclined surface 1513. The first inclined surface 1512 connects the bottom surface 1511 and the second inclined surface 1513, and the second inclined surface 1513 connects to the first surface 15. The inclination angle of the first inclined surface 1512 relative to the first surface 15 is greater than the inclination angle of the second inclined surface 1513 relative to the first surface 15.

[0322] Understandably, the first inclined surface 1512 and the second inclined surface 1513 are connected to form a guide surface. The relatively gentle second inclined surface 1513 smoothly connects the first inclined surface 1512 and the first surface 15, which is conducive to the protrusion entering or leaving the groove along the second inclined surface 1513. At the same time, the relatively steep first inclined surface 1512 has a certain limiting effect on the protrusion. The protrusion is well kept within the limited range of the first inclined surface 1512 without external force, and the protrusion can leave along the first inclined surface 1512 under the action of external force.

[0323] In other embodiments, the elastic arm 322" may not abut against the first surface 15 (not shown in the figure) without the mating structure 3221. For example, the top surface of the elastic arm 322" abuts against the first surface 15, and the mating structure 3221 is provided on the side of the elastic arm 322" with a gap between the mating structure 3221 and the first surface 15. A first positioning structure 151 with a protrusion is provided on the first surface 15. The first positioning structure 151 has an opening facing the side of the elastic arm 322" and the mating structure 3221 can be an elastic protrusion on the side of the elastic arm 322" when the clamping mechanism 3 rotates to the clamping position, the elastic protrusion enters the hole. It is understood that the first positioning structure 151 can also be other structures, such as a retaining ring or a clamp.

[0324] In some embodiments, the first surface 15 is provided with a second positioning structure 152, and the mating structure 3221 cooperates with the second positioning structure 152 to position the clamping mechanism 3 in the release position. Besides its positioning function, when the clamping mechanism 3 rotates to the point where the mating structure 3221 engages with the second positioning structure 152, it also serves as a prompt to the operator to prevent excessive rotation of the clamping mechanism 3 and potential damage. The structure of the second positioning structure 152 can be configured with reference to any embodiment of the first positioning structure 151, and will not be described in detail here.

[0325] There are various structures for the base 1 and the clamping mechanism 3, as long as the base 1 and the clamping mechanism 3 can cooperate to clamp the expansion module 2001.

[0326] In some embodiments, as shown in FIG29, the base 1 includes a first sidewall 11", a second sidewall 12", a third sidewall 13", and a pivot connector 14". The second sidewall 12" and the pivot connector 14" are respectively disposed at both ends of the first sidewall 11". The third sidewall 13" is connected to the second sidewall 12" and is opposite to and spaced apart from the first sidewall 11". The connector 2 is disposed on the second sidewall 12", and the clamping mechanism 3 is connected to the pivot connector 14". The third sidewall 13" is spaced apart from the first sidewall 11" to form an opening for the expansion module 2001 to enter and exit. The clamping mechanism 3 opens the opening in the release position, allowing the expansion module 2001 to enter between the third sidewall 13" and the first sidewall 11" and be inserted into the connector 2. The clamping mechanism 3 closes the opening in the clamping position and abuts against the expansion module 2001, so that the first sidewall 11", the second sidewall 12", the third sidewall 13" and the clamping mechanism 3 cooperate to surround the expansion module 2001.

[0327] In addition, in some embodiments, the base 1 further includes a fourth sidewall 17", to which the first sidewall 11", the second sidewall 12", and the third sidewall 13" are all connected. The fourth sidewall 17" can serve as a component to support the expansion module 2001, thereby reducing the force exerted by the gravity of the expansion module 2001 on the connector 2.

[0328] In some embodiments, the base 1 further includes a fifth sidewall (not shown in the figure), which is disposed opposite to the fourth sidewall 17", and the first sidewall 11", the second sidewall 12", and the third sidewall 13" are all connected to the fifth sidewall. The fifth sidewall can serve as a component covering the expansion module 2001 to better fix and protect the expansion module 2001.

[0329] In the embodiments provided in this disclosure, the first surface 15" may be disposed on any one of the first sidewall 11", the second sidewall 12", the third sidewall 13", the fourth sidewall 17", and the fifth sidewall. For example, the side of the fourth sidewall 17" facing away from the expansion module 2001 may be used as the first surface 15", and the elastic arm 322" may extend to the bottom of the base 1 and abut against the fourth sidewall 17".

[0330] In some embodiments, the first surface 15" is disposed on the pivot connector 14".

[0331] Referring again to Figure 29, the pivot connector 14" includes a first connecting portion 141 and a second connecting portion 142, which are disposed opposite to each other. The clamping mechanism 3 is rotatably connected between the first connecting portion 141 and the second connecting portion 142. As shown in Figures 29 and 30, the clamping mechanism 3 is provided with a bushing 313. The pivot connector 14" also includes a rotating shaft 143, which passes through the bushing 313, and the two ends of the rotating shaft 143 are respectively fixedly connected to the first connecting portion 141 and the second connecting portion 142.

[0332] The first surface 15" is located in the first connecting portion 141 and / or the second connecting portion 142. That is, the first connecting portion 141 has the first surface 15", or the second connecting portion 142 has the first surface 15", or the first connecting portion 141 and the second connecting portion 142 each have the first surface 15". By setting the first surface 15" in the first connecting portion 141 and / or the second connecting portion 142, the length of the elastic arm 322" is shorter, and the overall structure is more compact.

[0333] In some embodiments, the first connecting portion 141 and the second connecting portion 142 each have a first surface 15", as shown in FIG26. The two first surfaces 15" are located on opposite sides of the first connecting portion 141 and the second connecting portion 142. Correspondingly, the clamping mechanism 3 is provided with two elastic arms 322", which press against the two first surfaces 15". Thus, the free ends of the elastic arms 322" are located between the first connecting portion 141 and the second connecting portion 142, without occupying additional vertical (Z-direction) space and are less likely to interfere with external structures. Furthermore, under the action of the two elastic arms 322", frictional damping is generated at both ends, making the clamping mechanism 3 more stable vertically and less prone to tilting, ensuring a stable and smooth rotation process.

[0334] In some embodiments, as shown in FIG29, the clamping mechanism 3 includes a base 31 and a clamping member 32. The base 31 is rotatably connected to the base 1, and the clamping member 32 is disposed on the base 31 for clamping one end of the extension module 2001.

[0335] The elastic arm 322" provided in this embodiment can be disposed on the base 31 or on the clamping member 32. In some embodiments, the elastic arm 322" is configured as part of the clamping member 32, thereby achieving a rotatable connection between the base 31 and the base 1, and achieving a pressing and frictional engagement using the clamping member 32.

[0336] Please refer to Figure 29 again. The base 31 has a plate-like structure, and the aforementioned bushing 313 is disposed at one end of the base 31.

[0337] As shown in Figures 29 and 30, the clamping component 32 includes a first part 321", which is fixed to the base 31 by means of screw anchoring or bonding. The side of the first part 321" facing away from the base 31 is used to clamp the expansion module 2001.

[0338] The flexible arm 322" is connected to the end face of the first part 321" at one end in the vertical direction and extends toward the bushing 313.

[0339] In some embodiments, as shown in FIG27, the first part 321" has a notch on its vertical (Z direction) end face, and a limiting surface 3211" facing the elastic arm 322" is formed at the notch. The notch increases the elasticity of the elastic arm 322", and the limiting surface 3211" restricts the excessive deformation of the elastic arm 322" to avoid damage caused by excessive force on the elastic arm 322".

[0340] In some embodiments, the clamping member 32 further includes a second portion 323", which is connected to the first portion 321" in an L-shape to improve the clamping member 32's resistance to deformation. In some embodiments, reinforcing ribs are provided at the corner position between the second portion 323" and the first portion 321" to further improve the structural strength of the clamping member 32.

[0341] In some embodiments, referring to FIG30, the base 31 includes a central region 311" and an edge region 312" with the edge region 312" surrounding the central region 311". A clamping member 32 is disposed on the edge region 312" and the central region 311" protrudes relative to the edge region 312". The clamping mechanism 3 not only clamps the end position of the expansion module 2001 through the clamping member 32, but also clamps the middle position of the expansion module 2001 through the central region 311.

[0342] In some embodiments, the clamping mechanism 3 further includes a buffer 33 disposed in the central region 311". As shown in FIG29, the buffer 33 has a layered structure and is located within the edge range of the central region 311". It serves to protect the expansion module while allowing the expansion module 2001 to have certain manufacturing tolerances. The buffer 33 is made of a flexible material, such as rubber, polyethylene, polypropylene, polyurethane, silicone, etc.

[0343] The central region 311" includes a first end and a second end. The first end is relatively close to the clamping member 32. The buffer member 33 has a first gap with the first end of the central region 311" and a second gap with the second end of the central region 311" where the second gap is larger than the first gap. The first gap allows for a certain distance between the clamping member 32 and the buffer member 33, allowing for certain manufacturing tolerances between them to prevent them from contacting and squeezing each other. The second gap allows the expansion module 2001 to have functional components or interfaces at corresponding positions within the second gap, preventing damage to the functional components or interfaces due to pressure.

[0344] In some embodiments, as shown in Figures 29 and 30, the base 31 is configured to extend to the third sidewall 13", and the end of the base 31 facing away from the bushing 313 has a bent portion 314. As shown in Figure 26, when the clamping mechanism 3 is in the clamped position, the bent portion 314 is located on the side of the third sidewall 13" facing away from the first sidewall 11" for engaging and fixing with the third sidewall 13". Optionally, the bent portion 314 is provided with a locking member 315, and the third sidewall 13" is provided with a locking hole, the locking member 315 being connected to the locking hole to lock the clamping mechanism 3 in the clamping position.

[0345] In some embodiments, as shown in FIG29, the base 1 further includes a guide structure 16". The guide structure 16" is provided on the first sidewall 11" and / or the third sidewall 13" to guide the expansion module 2001 to be inserted and engaged with the connector 2. That is, the guide structure 16" is provided on the first sidewall 11", or on the third sidewall 13", or on both the first sidewall 11" and the third sidewall 13", to limit the movement path of the expansion module 2001 after it enters between the first sidewall 11" and the third sidewall 13", thereby guiding the expansion module 2001 to be inserted into the connector 2.

[0346] In other embodiments of this disclosure, the base 1 and the pressing mechanism 3 may also have other structural forms.

[0347] For example, the base 1 includes a first sidewall 11", a second sidewall 12", and a pivot connector 14". The second sidewall 12" and the pivot connector 14" are respectively disposed at both ends of the first sidewall 11". The connector 2 is disposed on the second sidewall 12". The clamping mechanism 3 is connected to the pivot connector 14". That is, the base 1 is L-shaped, and the clamping mechanism 3 cooperates with the second sidewall 12" to clamp the expansion module 2001 when in the clamping position.

[0348] For example, the base 1 includes a second sidewall 12", and the clamping mechanism 3 is constructed in an L-shape. The connector 2 is disposed on the second sidewall 12". The L-shaped clamping mechanism 3 is rotatably connected to the second sidewall 12". When the L-shaped clamping mechanism 3 is in the clamping position, it cooperates with the second sidewall 12" to clamp the expansion module 2001.

[0349] According to a second aspect of this disclosure, as shown in FIG31, an expansion module 2000 is provided, the expansion module 2000 including an expansion module 2001 and a fixing device 2002 provided in any of the preceding embodiments.

[0350] According to a third aspect of this disclosure, as shown in FIG32, a server is provided, the server including an expansion module 2000 provided in the second aspect, and a chassis 1000 for accommodating the expansion module 2000.

[0351] In the description of the embodiments of this disclosure, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
