Description

Technical Field

[0001] This invention relates to the field of quick-connect technology, and more particularly to a quick-connect structure and control box. Background Technology

[0002] In the field of medical equipment, many devices require air pumps to deliver air to other components for detection or treatment. Such devices typically consist of a control box and external components. The air pump is located inside the control box, and the external components are connected to the control box using a quick-connect structure.

[0003] For existing quick-connect structures, refer to patent CN209316438U, which discloses a quick-connect structure including a single-row connector and a socket fixed to the control box housing. The socket structure is similar to the multi-row shunt connector structure in that patent. The single-row connector has a pressing plate, a flexible connecting part, and a hook on its side wall, and a slot is provided on the side wall of the socket. When the single-row connector is engaged with the socket, the hook is located in the slot. During disassembly, the operator squeezes the pressing plate, causing the flexible connecting part to deform, thereby moving the hook outward. At this time, the hook and the slot separate, and pulling out the single-row connector separates the socket from the single-row connector. The installation process is similar to the disassembly process: after squeezing the pressing plate to deform the flexible connecting part, insert the single-row connector into the socket, align the hook and the slot, and then release the pressing plate.

[0004] The drawback of the above technology is that the pressing plate, flexible connection part and hook are generally integrally molded, mostly made of plastic injection molding. With the increase of disassembly and assembly, the flexible connection part is prone to irreparable deformation due to fatigue, resulting in the failure of the buckle. If the buckle fails, the entire single row connector needs to be replaced. Summary of the Invention

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0045] Example 1

[0046] In existing technologies, quick-connect structures integrate a pressing plate, a flexible connecting part, and a latch in the plug. A slot is provided on the side wall of the socket. When the plug is inserted into the socket, the latch is positioned within the slot. During disassembly and installation, workers need to press the pressing plate to deform the flexible connecting part, causing the latch to move outward. Disassembly involves pulling the plug outward to separate the socket from the plug. Installation involves inserting the plug into the socket, aligning the latch with the slot, and then releasing the pressing plate. In these technologies, the plug is typically molded from a single piece of plastic. With prolonged use, the flexible connecting part repeatedly deforms, easily leading to irreparable deformation due to fatigue, causing the latch to fail. Furthermore, once the latch fails, the entire plug needs to be replaced, resulting in high costs.

[0047] To address the aforementioned problems, this invention introduces a quick-connect structure, such as... Figure 1As shown, the device includes a socket 1 and a plug assembly 2. The plug assembly 2 is inserted into the socket 1 and can be snapped in and disassembled after insertion. An air hose connector 3 is provided on the plug assembly 2, and the air hose connector 3 is fixedly connected to the plug assembly 2. A cylindrical connector 12 is provided inside the socket 1, and an air hose is connected to the inside of the connector 12. When the plug assembly 2 is snapped into the socket 1, the air hose connector 3 aligns with and connects to the connector 12, thus connecting the air hose and the air hose. A sealing ring can also be provided between the air hose connector 3 and the connector 12 to increase the sealing performance between them.

[0048] Specifically, such as Figure 1 and Figure 2 As shown, the plug-in assembly 2 includes a fixing member 21, a moving member 22, and an elastic member 23.

[0049] Both the fixing member 21 and the moving member 22 are hollow shells. The fixing member 21 and the moving member 22 are fastened together, that is, the moving member 22 is housed in the fixing member 21, or the fixing member 21 is housed in the moving member 22. In this embodiment, the moving member 22 is housed in the fixing member 21. In other embodiments, the fixing member 21 can be housed in the moving member 22.

[0050] Furthermore, the movable component 22 is configured to partially or fully enclose the fixed component 21. In this embodiment, the movable component 22 is partially enclosed within the fixed component 21 to facilitate the disassembly of the movable component 22 and the fixed component 21. In other embodiments, the movable component 22 may also be fully enclosed within the fixed component 21.

[0051] like Figure 2 As shown, after the fixing member 21 and the moving member 22 are engaged, there is a gap 24 between the side wall of the fixing member 21 and the side wall of the moving member 22 in at least one direction. The moving member 22 and the fixing member 21 are slidably connected, and the sliding direction of the moving member 22 is perpendicular to the gap 24, that is, the gap 24 provides space for the sliding of the moving member 22. When the moving member 22 and the fixing member 21 slide, the elastic member 23 is mainly used to reset the position between the moving member 22 and the fixing member 21. The two ends of the elastic member 23 correspond one-to-one with the fixing member 21 and the moving member 22 and abut or fix them.

[0052] When the plug-in assembly 2 is plugged into the socket 1, the fixing member 21 engages with the socket 1, and the moving member 22 engages with the socket 1. As the moving member 22 slides within the fixing member 21, the moving member 22 and the socket 1 can be in an engaged or disengaged state, thus enabling the plug-in assembly 2 and the socket 1 to be installed or removed. At this time, the elasticity of the elastic member 23 keeps the positions of the moving member 22 and the fixing member 21 stable, thereby maintaining the engaged state between the moving member 22 and the socket 1.

[0053] Optionally, the cross-section of the fixing member 21 and / or the moving member 22 is square, circular or oblong, or of course other shapes. In this embodiment, the fixing member 21 and the moving member 22 are square.

[0054] Optional, such as Figure 1 and Figure 3 As shown, a hook 222 is provided on the side wall of the movable part 22 parallel to the sliding direction of the movable part 22. The hook 222 is generally integrally formed with the movable part 22. A positioning part 11 is provided on the side wall of the socket 1. When the fixing part 21 is inserted into the socket 1, after the movable part 22 slides, the hook 222 abuts against or disengages from the positioning part 11. Applying an external force to the movable part 22 causes it to slide relative to the fixed part 21, i.e., the movable part 22 slides relative to the socket 1, causing the hook 222 to disengage from the positioning part 11. At this time, pulling out the plug assembly 2 will smoothly ensure that the movable part 22 and the socket 1 are disengaged. If it is necessary to install the plug assembly 2 and the socket 1, the same external force is applied to the movable part 22 to cause it to slide relative to the fixed part 21, i.e., the movable part 22 slides relative to the socket 1. The elastic part 23 will deform due to the sliding of the movable part 22 relative to the fixed part 21. At this time, the position of the hook 222 will avoid the positioning part 11, and the fixed part 21 and the socket 1 will be inserted. After the external force is removed, the elastic part 23 will use its elasticity to reset the position between the movable part 22 and the fixed part 21. The hook 222 will abut against the positioning part 11. At this time, the movable part 22 and the socket 1 are engaged, ensuring that the movable part 22 and the socket 1 can maintain a stable engagement in the natural state without the application of external force.

[0055] In this embodiment, as Figure 3 As shown, the positioning part 11 protrudes from the side wall of the socket 1. The positioning part 11 is provided with a sliding surface 111, which is inclined. During the insertion and engagement of the plug assembly 2 and the socket 1, the hook 222 on the moving part 22 contacts the sliding surface 111 and can slide along the sliding surface 111, forcing the moving part 22 to slide relative to the fixed part 21. When the hook 222 slides to the end of the sliding surface 111, under the elastic force of the elastic member 23, the moving part 22 returns to its original position, driving the hook 222 to move and engage with the positioning part 11. At this time, during the insertion and installation of the plug assembly 2, no external force needs to be applied to the moving part 22 manually; the movement of the hook 222 along the sliding surface 111 is sufficient to drive the moving part 22 to slide relative to the fixed part 21.

[0056] The side of the hook 222 can also be set as an inclined curved surface so that the moving part 22 and the fixed part 21 can slide between each other during the process of inserting the plug assembly 2 into the socket 1.

[0057] In other embodiments, the positioning part 11 may also be a slot formed on the side wall of the socket 1. Similarly, in other embodiments, the hook 222 may also be provided on the side wall of the socket 1, and the positioning part 11 may be provided on the moving member 22.

[0058] The fixing member 21 and the moving member 22 need to be fixed along the insertion direction of the plug-in assembly 2 and the socket 1, and the moving member 22 and the fixing member 21 need to slide in a direction perpendicular to the gap 24. At this time, a limiting structure needs to be provided between the fixing member 21 and the moving member 22. For example, a waist-shaped hole can be opened on the side wall of both the fixing member 21 and the moving member 22, with the length direction of the waist-shaped hole being the same as the sliding direction of the moving member 22. A limiting pin is inserted into the waist-shaped hole, so that the limiting pin passes through both the fixing member 21 and the moving member 22, thereby limiting the position of the fixing member 21 and the moving member 22 along the insertion direction of the plug-in assembly 2 and the socket 1. Alternatively, the moving member 22 can be completely housed within the fixing member 21, thereby limiting the position of the fixing member 21 and the moving member 22 along the insertion direction of the plug-in assembly 2 and the socket 1.

[0059] In this embodiment, as Figure 2 As shown, the positions of the fixed part 21 and the movable part 22 are limited by the air pipe connector 3. One end of the air pipe connector 3 is provided with a retaining ring 31, and the other end is provided with an external thread. The retaining ring 31 protrudes from the outer circumferential surface of the air pipe connector 3. When installing the air pipe connector 3, the air pipe connector 3 passes through the bottom of the fixed part 21 and the bottom of the movable part 22, and the air pipe connector 3 is fixedly connected to the fixed part 21. The movable part 22 has an elongated hole for the air pipe connector 3 to pass through. At this time, the retaining ring 31 and the external thread are located on both sides corresponding to the fixed part 21 and the movable part 22, respectively. Then, a fixing bolt 32 is connected to the external thread of the air pipe connector 3, so that the fixing bolt 32 and the retaining ring 31 can be used to limit the fixed part 21 and the movable part 22, preventing the fixed part 21 and the movable part 22 from separating from each other. When the movable part 22 slides in the fixed part 21, the air pipe connector 3 can move relative to it in the elongated hole, ensuring the smooth sliding of the movable part 22.

[0060] In this embodiment, the elastic element 23 is a spring. Of course, in other embodiments, the elastic element 23 can also be other elastic structures, such as elastic rubber. The position of the elastic element 23 can also be varied, depending on whether it can reset the position of the moving element 22 within the fixed element 21. To position the elastic element 23 and ensure its deformation direction, alternatively, such as... Figure 2 As shown, a receiving portion 25 is fixedly provided inside the fixing member 21 or the moving member 22. The receiving portion 25 is a rib protruding from the fixing member 21 or the moving member 22. The elastic member 23 is received inside the receiving portion 25, so that the elastic member 23 deforms in the receiving portion 25. And through the restriction of the receiving portion 25, the elastic member 23 is guaranteed to deform along the length direction of the receiving portion 25.

[0061] To improve the reliability and stability of the sliding between the moving part 22 and the fixed part 21, optionally, a guide structure is provided between the moving part 22 and the fixed part 21 to guide the sliding of the moving part 22. In this embodiment, as shown... Figure 2 As shown, the guiding structure consists of a guide plate 41 and a guide groove 42. The guide plate 41 and the guide groove 42 are respectively disposed on the fixing member 21 and the moving member 22. Specifically, in this embodiment, the guide plate 41 is integrally disposed on the fixing member 21, and the guide groove 42 is formed in the moving member 22. The guide plate 41 and the guide groove 42 are slidably engaged, and the length direction of the guide plate 41 is the same as the sliding direction of the moving member 22. The guide groove 42 can be formed on any side wall of the moving member 22. In this embodiment, the guide groove 42 is formed on the end plate of the accommodating part 25 and the side wall of the moving member 22.

[0062] In other embodiments, the guide structure can be a structure of a guide rod and a guide hole, with the guide rod inserted into the guide hole. The guide rod and the guide hole are respectively provided on the fixed member 21 and the movable member 22, and the length direction of the guide rod is the same as the sliding direction of the movable member 22.

[0063] In addition, there are two ways to connect the fastener 21 to the socket 1: one is to connect the fastener 21 to the inside of the socket 1, and the other is to connect the fastener 21 to the outside of the socket 1.

[0064] There are two types of engagement relationships between the movable part 22 and the fixed part 21: one is that the movable part 22 is engaged within the fixed part 21, and the other is that the fixed part 21 is engaged within the movable part 22.

[0065] The positional relationship between the movable part 22, the fixed part 21 and the socket 1 also includes two types: one is that the movable part 22 is located between the fixed part 21 and the socket 1, and the other is that the fixed part 21 is located between the movable part 22 and the socket 1.

[0066] In the implementation method described in this embodiment, such as Figure 4 As shown, the movable part 22 is located between the fixed part 21 and the socket 1. The movable part 22 is fastened inside the fixed part 21, and the fixed part 21 is inserted into the inside of the socket 1.

[0067] Optional, such as Figure 2As shown, a clearance hole 211 is provided on one side wall of the fixing member 21, and a pressing key 223 is protruding from the side wall of the moving member 22. The pressing key 223 is located inside and extends out of the clearance hole 211, and the sliding direction of the pressing key 223 within the clearance hole 211 is the same as the sliding direction of the moving member 22. At this time, the pressing key 223 can be pressed from the outside of the fixing member 21, thereby driving the moving member 22 to slide within the fixing member 21, causing the locking structure between the moving member 22 and the socket 1 to disengage, so as to facilitate disassembly or installation.

[0068] like Figure 1 As shown, a clearance groove 212 is provided on the side wall corresponding to the fastener 21 and the hook 222 to provide space for the movement and installation of the hook 222.

[0069] The working principle of this embodiment is as follows:

[0070] During the process of connecting the plug assembly 2 to the socket 1, first align the fixing member 21 with the socket 1, and then gradually push the plug assembly 2 into the socket 1. During the pushing process, the hook 222 on the moving member 22 contacts the sliding surface 111 on the positioning part 11, and the hook 222 can slide along the sliding surface 111, forcing the moving member 22 to slide relative to the fixing member 21. When the hook 222 slides to the end of the sliding surface 111, under the elastic force of the elastic member 23, the moving member 22 returns to its original position, driving the hook 222 to move to engage with the positioning part 11.

[0071] When it is necessary to disassemble the plug assembly 2 and the socket 1, press the press button 223. The press button 223 will cause the moving part 22 to slide within the fixed part 21, so that the hook 222 and the positioning part 11 are disengaged. At this time, the plug assembly 2 can be pulled out to achieve separation.

[0072] Example 2

[0073] like Figure 10 As shown, the difference from Embodiment 1 is that in this embodiment, the fixing member 21 and the moving member 22 are oblong, and the sliding direction of the moving member 22 and the fixing member 21 is the length direction of the oblong hole.

[0074] Furthermore, when the plug assembly 2 is plugged into the socket 1, the fixing member 21 is located between the moving member 22 and the socket 1, and the moving member 22 is completely surrounded by the fixing member 21. In order to facilitate the installation of the moving member 22, the fixing member 21 is installed using a half-type splicing method.

[0075] The air pipe connector 3 is completely fixed to the fixing member 21. The bottom of the fixing member 21 has a hole for the connector 12 to be inserted. The moving member 22 has an elongated hole through which the air pipe connector 3 passes. When the moving member 22 moves relative to the fixing member 21, the air pipe connector 3 can move relative to the moving member 22 within the elongated hole.

[0076] like Figure 12 As shown, in this embodiment, the guide structure between the fixing member 21 and the moving member 22 includes a guide post 411 and a guide hole 421. The guide post 411 and the guide hole 421 are respectively disposed on the fixing member 21 and the moving member 22. The guide post 411 and the guide hole 421 are inserted and slidably engaged. The length direction of the guide post 411 is the same as the sliding direction of the moving member 22. Furthermore, the guide hole 421 is a stepped hole. The guide post 411 is inserted and slidably engaged with the smaller diameter part of the guide hole 421. The elastic member 23 is housed in the larger diameter hole of the guide hole 421. The guide post 411 passes through the elastic member 23. One end of the elastic member 23 abuts against the stepped surface of the guide hole 421, and the other end abuts against the inner surface of the fixing member 21. Thus, the elastic force of the elastic member 23 can be used to reset the moving member 22 and the fixing member 21.

[0077] Example 3

[0078] The difference from Embodiment 1 is that the positional relationship between the fixing member 21, the moving member 22 and the socket 1 is different.

[0079] Specifically, such as Figure 5 As shown, the fixing member 21 is fastened inside the moving member 22, and the fixing member 21 is inserted into the inner side of the socket 1. At this time, the socket 1 has a protruding insert plate 13, the positioning part 11 is disposed on the insert plate 13, the fixing member 21 is inserted into the inner side of the insert plate 13, that is, the inner side of the socket 1, the insert plate 13 is located between the fixing member 21 and the moving member 22, and the moving member 22 is engaged with the insert plate 13.

[0080] Alternatively, the movable part 22 can be located between the fixed part 21 and the socket 1, or the fixed part 21 can be located between the movable part 22 and the socket 1. When the movable part 22 is located between the fixed part 21 and the socket 1, the insert plate 13 can be inserted between the movable part 22 and the fixed part 21 by passing through the movable part 22.

[0081] Example 4

[0082] The difference from Embodiment 1 is that the positional relationship between the fixing member 21, the moving member 22 and the socket 1 is different.

[0083] Specifically, such as Figure 6 As shown, the movable part 22 is fastened inside the fixed part 21, and the fixed part 21 is inserted into the outside of the socket 1. At this time, the socket 1 has a protruding insert plate 13, the positioning part 11 is disposed on the insert plate 13, the fixed part 21 is inserted into the outside of the insert plate 13, that is, the outside of the socket 1, the insert plate 13 is located between the fixed part 21 and the movable part 22, and the movable part 22 is engaged with the insert plate 13.

[0084] Alternatively, the movable part 22 can be located between the fixed part 21 and the socket 1, or the fixed part 21 can be located between the movable part 22 and the socket 1. When the fixed part 21 is located between the movable part 22 and the socket 1, the insert plate 13 can be inserted between the movable part 22 and the fixed part 21 by passing through the fixed part 21.

[0085] Example 5

[0086] The difference from Embodiments 1 to 4 is that the movable member 22 and the fixed member 21 are rotatably connected. The movable member 22 and the fixed member 21 are generally cylindrical so that the movable member 22 can rotate relative to the fixed member 21.

[0087] When the plug-in assembly 2 is plugged into the socket 1, the fixing member 21 engages with the socket 1, and the moving member 22 engages with the socket 1. As the moving member 22 rotates within the fixing member 21, the moving member 22 and the socket 1 can be in an engaged state or disengaged state, thus enabling the plug-in assembly 2 and the socket 1 to be installed or removed. At this time, the elasticity of the elastic member 23 ensures that the positions of the moving member 22 and the fixing member 21 remain stable, thereby maintaining the engaged state between the moving member 22 and the socket 1.

[0088] The elastic element 23 can be configured as a torsion spring or similar structure.

[0089] Example 6

[0090] like Figure 7 As shown, this embodiment introduces a control box, including any of the quick-connect structures in Embodiments 1 to 5. The control box includes a box body 6, and an air pump is installed inside the box body 6. The air outlet of the air pump is connected to a connector 12 on a socket 1 through an air pipe. The socket 1 is located on the outer wall of the box body 6. The air pipe connector 3 is connected to the air pipe of an external device. The box body 6 achieves quick installation or removal from the external device through the quick-connect structure.

[0091] Example 7

[0092] like Figure 8 As shown, based on Embodiment Six, the end of the plug assembly 2 furthest from the socket 1 has a protective shell 4 and a switching element 5. The protective shell 4, the switching element 5, and the plug assembly 2 form a plug. One end of the protective shell 4 is sealed to the fixing element 21, and the other end is connected to the switching element 5. The switching element 5 is configured to switch the connection or closure between the protective shell 4 and the switching element 5. Figure 11As shown, the end of the protective shell 4 near the switching element 5 has a connection hole 44 that is sealed to the air pipe connector 3. The connection hole 44 and the switching element 5 are connected by the switching element 5. At this time, the air pump can supply air to the external device through the connection hole 44 and the switching element 5. When the plug assembly 2 needs to be pulled out of the housing 6, the connection hole 44 and the switching element 5 are sealed by the switching element 5 first, so as to maintain the pressure of the external device. Then the plug assembly 2 is pulled out, which can prevent the pressure in the external device from being quickly released from the air pipe connector 3 in the protective shell 4 after the plug assembly 2 is pulled out.

[0093] The end of the protective shell 4 with the connection hole 44 can be integrally connected to the protective shell 4, or it can be connected separately from the protective shell 4, using the half-type structure of the protective shell 4 for fixing and sealing.

[0094] Specifically, the switching component 5 has a connecting hole 51. The switching component 5 is rotatably connected to the end of the protective shell 4. Rotation of the switching component 5 and the protective shell 4 can achieve connection or misalignment between the connecting hole 44 and the connecting hole 51. After rotating the switching component 5 to align and connect the connecting hole 44 and the connecting hole 51, normal airflow can be supplied from the air pump to the external equipment. When the switching component 5 is rotated to misalign the connecting hole 44 and the connecting hole 51, the connecting hole 44 and the connecting hole 51 are not connected, and pressure can be maintained for the external equipment.

[0095] The switching component 5 and the protective shell 4 are rotatably connected to each other via a rotating component, which can be a bolt or a rotating shaft. When the rotating component is a bolt, tightening the bolt can increase the distance between the switching component 5 and the protective shell 4, ensuring a better seal when the connecting hole 44 and the connecting hole 51 are misaligned.

[0096] Additionally, the rotation angle of the switching element 5 and the protective shell 4 can be limited, generally to within 90°. Of course, it can also be any other angle, as long as it ensures that switching between connection and misalignment between the connecting hole 44 and the connecting hole 51 is possible. Markings can also be made on the outside of the switching element 5 and the protective shell 4 to determine the connection status between them.

[0097] When the plug assembly 2 is inserted into the socket 1, if the insertion depth of the plug assembly 2 is insufficient, it may cause insufficient insertion between the air pipe connector 3 and the housing 6, resulting in air leakage. To solve the above problem, alternatively, such as Figure 8 and 9As shown, a micro switch is provided on the back of the socket 1. The micro switch includes a switch spring 61. One end of the switch spring 61 is fixed to the back of the socket 1, and the other end extends into the socket 1. When the plug assembly 2 is inserted into the socket 1, the plug assembly 2 deforms the switch spring 61 by squeezing it. The bottom or side wall of the socket 1 is generally provided with a clearance hole 14. The free end of the switch spring 61 extends into the socket 1 through the clearance hole 14. During the process of inserting the plug assembly 2 into the socket 1, once the plug assembly 2 is inserted in place, the plug assembly 2 will touch the switch spring 61 and cause the switch spring 61 to deform. After the switch spring 61 deforms, it generates a signal that can be transmitted to the controller. After receiving the signal, the controller determines that the plug assembly 2 has been inserted; otherwise, it indicates that the plug assembly 2 has not been inserted or is incorrectly inserted.

[0098] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
