[0001] The present application relates to the technical field of medical devices, and in particular to a positioning component, a mounting component, and a mounting assembly. Background Art

[0002] In the medical device field, particularly in blood purification treatments, extracorporeal circuit components must remain sealed before connecting to the device to maintain a sterile environment. These components, such as connector caps and pressure sensor covers, are typically connected via threaded connections to facilitate removal and reconnection of the tubing when needed.

[0003] However, existing threaded connections carry the risk of falling apart, particularly during production, transportation, or clinical operation. Once a component falls off, it not only compromises the sterile environment within the tubing, but can also waste consumables and even threaten patient safety. Therefore, an improved component design is needed to address the issue of falling apart during medical device use and ensure the stability and safety of the tubing system. Utility Model Content

[0025] The present application also provides a mounting component, including:

[0026] The mounting sleeve has an at least partial open cavity formed therein for accommodating the positioning component. A third threaded structure is provided inside the mounting sleeve, and the third threaded structure is used to be connected to the first threaded structure and / or the second threaded structure.

[0027] In some embodiments, a matching structure is further provided inside the mounting sleeve, and the matching structure is used for interference fit with the limiting portion; and / or,

[0028] The third thread structure is a double-thread helix.

[0029] The present application also provides a mounting assembly, comprising a positioning component and a mounting component, wherein the mounting component is connected to the positioning component;

[0030] Wherein, the positioning component is the above-mentioned positioning component, and the installation component is the above-mentioned installation component.

[0031] Compared with the above-mentioned background technology, the positioning component provided by the present application mainly includes a positioning rod, a fixing part and a movable part. The positioning rod is provided with a connected rod portion and a limiting part. The rod portion is extended in the first direction, and the limiting part is located at the first end of the rod portion in the first direction; the fixing part is fixedly sleeved on the rod portion, and the fixing part is provided with a first threaded structure; the movable part is movably sleeved on the rod portion, and the movable part can move along the first direction and rotate around the first direction.

[0032] In the medical device field, especially in blood purification therapy, the stability of the extracorporeal circulation tubing system is crucial. Existing threaded connections carry the risk of falling off during production, transportation, or clinical operation, which can lead to damage to the sterile environment, waste of consumables, and even threaten patient safety. To address this issue, this application proposes an innovative positioning component design.

[0033] Take, for example, the threaded connection of a mounting component to a positioning component. During normal installation, the fixed and movable components are combined into one piece through the connection between the fixed structure and the movable structure. The threads of the fixed and movable components are continuous, which means that the mounting component can be installed on the positioning component through the second thread structure and then the first thread structure.

[0034] Subsequently, when the external environment changes or other factors cause the installation component to tend to fall off, even if the installation component disengages and retreats from the first thread structure of the fixed component, it will not continue to disengage and retreat from the second thread structure of the movable component. This is because the movable component can move freely on the rod, so the movable component is separated from the combination with the fixed component, and the movable component will move with the installation component. At this time, the movement range of the movable component is limited, and the movable component and the installation component no longer produce relative rotation, so the process of the installation component disengaging and retreating on the movable component is stopped, thereby avoiding the occurrence of falling off.

[0035] This mechanism effectively prevents installed components from falling off, even when affected by the external environment, ensuring the stability and safety of the piping system. This innovative design significantly improves the reliability of key components in medical devices, reduces the risks associated with unstable connections, and provides safer and more reliable protection for clinical operations.

[0036] Combined with the above structure and process description, it can be seen that the positioning component has at least the following beneficial effects: the positioning component enhances the anti-falling performance through the innovative matching mechanism of the movable thread and the fixed thread, ensuring that the stability and security of the connection can be maintained even when affected by the external environment.

[0054] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0055] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0056] In the accompanying drawings, coordinate axes are marked, and the directions indicated by the coordinate axes are consistent with the directions described in the present application. Coordinate axis X represents a first direction, which is also the length direction, left-right direction, and axial direction.

[0057] Please refer to Figure 1 , Figure 1 A schematic diagram of a positioning component provided in an embodiment of the present application.

[0058] In a specific embodiment, the positioning component 100 provided by the embodiment of the present application mainly includes a positioning rod 1, a fixing part 2 and a movable part 3. The positioning rod 1 is provided with a connected rod portion 11 and a limiting part 12. The rod portion 11 is extended in a first direction, and the limiting part 12 is located at the first end of the rod portion 11 in the first direction; the fixing part 2 is fixedly sleeved on the rod portion 11, and the fixing part 2 is provided with a first threaded structure 21; the movable part 3 is movably sleeved on the rod portion 11, and the movable part 3 can move along the first direction and rotate around the first direction. The moving range of the movable part 3 is limited by the limiting part 12 and the fixing part 2, and the movable part 3 is provided with a second threaded structure 31; wherein the first threaded structure 21 and the second threaded structure 31 have consistent thread parameters; the fixing part 2 is provided with a fixed structure 22, and the movable part 3 is provided with a movable structure 32. Through the combination of the fixed structure 22 and the movable structure 32, the first threaded structure 21 and the second threaded structure 31 form a continuous thread.

[0059] like Figure 1 As shown, the first end of the rod 11 is the left end in the figure, and the limiting portion 12 is located at the left end of the rod 11. The second end of the rod 11 is the right end in the figure, and the right end of the rod 11 can be provided with other structures, such as a bolt head.

[0060] In the medical device field, especially in blood purification therapy, the stability of the extracorporeal circulation tubing system is crucial. Existing threaded connections carry the risk of falling off during production, transportation, or clinical operation, potentially damaging the sterile environment, wasting consumables, and even threatening patient safety. To address this issue, this application proposes an innovative positioning component 100 design.

[0061] For example, the threaded connection of the mounting component 200 to the positioning component 100. During normal installation, the fixed structure 22 and the movable structure 32 combine to form a single unit, and the threads of the fixed and movable components 2 and 3 are continuous. This means that the mounting component 200 can be installed on the positioning component 100 sequentially via the second thread structure 31 and the first thread structure 21.

[0062] Subsequently, when the external environment changes or other factors cause the installation component 200 to tend to fall off, even if the installation component 200 disengages and retreats from the first threaded structure 21 of the fixed component 2, it will not continue to disengage and retreat from the second threaded structure 31 of the movable component 3. This is because the movable component 3 can move freely on the rod 11, so the movable component 3 is separated from the combination with the fixed component 2, and the movable component 3 will move with the installation component 200. At this time, the movement range of the movable component 3 is limited, and the movable component 3 and the installation component 200 no longer rotate relative to each other, so the process of the installation component 200 disengaging and retreating on the movable component 3 is stopped, thereby avoiding the occurrence of falling off.

[0063] This mechanism effectively prevents the mounting member 200 from falling off, even when affected by the external environment, ensuring the stability and safety of the piping system. This innovative design significantly improves the reliability of key components in medical devices, reduces the risks associated with unstable connections, and provides safer and more reliable clinical operations.

[0064] Combined with the above structure and process description, it can be seen that the positioning component 100 has at least the following beneficial effects: the positioning component 100 enhances the anti-falling performance through the innovative matching mechanism of the movable thread and the fixed thread, ensuring that the stability and safety of the connection can be maintained even when affected by the external environment.

[0065] In some cases, the connection between the mounting component 200 and the positioning component 100 can be regarded as the installation of a nut on a screw; its material includes but is not limited to plastic, metal, etc.; application scenarios include but are not limited to any screw and nut structure with anti-falling requirements such as blood circulation pipelines.

[0066] Optionally, in terms of the blood circulation pipeline, the installation component 200 can be a dust cap, a connector cap or other structures, or a protective cover such as a pressure sensor protective cover, and can be installed on the positioning component 100, with the help of the cooperation between the movable thread and the fixed thread to increase the anti-falling performance.

[0067] In addition, external environmental influences that may trigger the installation component 200 to fall off include but are not limited to vibration, temperature, etc., which should also fall within the scope of the description of this application.

[0068] Please continue to refer to Figure 1 And refer to Figure 2 , Figure 2 for Figure 1 Schematic diagram of the disengagement of the fixed and movable parts.

[0069] like Figure 1 As shown, the fixed structure 22 and the movable structure 32 are connected, and the fixed part 2 and the movable part 3 are in a combined state. At this time, the thread is continuous, and the screw installation function of the installation component 200 on the positioning component 100 can be normally realized. Figure 2 As shown, the fixed structure 22 and the movable structure 32 are separated, and the movable part 3 is disengaged from the fixed part 2. At this time, the thread is disconnected, which means that even if the installation component 200 is threaded out of the fixed part 2, it will not be threaded out of the movable part 3 because the free movement of the movable part 3 on the rod 11 will prevent the installation component 200 from being screwed out on the movable part 3.

[0070] It should be noted that this embodiment does not limit how the fixed structure 22 and the movable structure 32 are combined. For example, the fixed structure 22 and the movable structure 32 can be combined by abutment, the fixed structure 22 and the movable structure 32 can be combined by snapping, or the fixed structure 22 and the movable structure 32 can be combined by interference fit. These are not limited in this embodiment and should all fall within the scope of description of this embodiment.

[0071] Please continue to refer to Figure 2 In some embodiments, the fixed structure 22 is a block 221 and the movable structure 32 is a notch 321. In the first direction of the rod 11 and in the circumferential direction perpendicular to the first direction, the block 221 and the notch 321 are matched with each other in a concave-convex manner.

[0072] In this embodiment, the fixed structure 22 and the movable structure 32 are connected by abutment. The fixed structure 22 is in the form of a block 221, while the movable structure 32 is designed as a notch 321. The block 221 and the notch 321 interact with each other on the rod 11 in a concave-convex fit. Specifically, the block 221 is located on the fixed member 2, while the notch 321 is located on the movable member 3. In the first direction of the rod 11, and in the circumferential direction perpendicular to the first direction, the block 221 and the notch 321 can also achieve a concave-convex fit.

[0073] This design allows for a consistent fit between the fixed member 2 and the movable member 3 in both the axial and circumferential directions, thereby enhancing the stability of the connection. The concave-convex fit between the block 221 and the notch 321 effectively restricts the movement of the movable member 3 on the rod 11, ensuring the stability and reliability of the positioning component 100 during operation. This design also facilitates rapid assembly and disassembly of the fixed member 2 and the movable member 3, improving the overall structure's practicality and ease of operation.

[0074] Please continue to refer to Figure 2 In some embodiments, the clamping block 221 is provided at the first end of the fixing member 2 in the first direction. The clamping block 221 includes a clamping block vertical surface 2211 and a clamping block inclined surface 2212 connected to each other. The clamping block vertical surface 2211 is connected to the axial end surface of the first end of the fixing member 2 at a right angle, and the clamping block inclined surface 2212 is connected to the axial end surface of the first end of the fixing member 2 at a first inclined angle.

[0075] The notch 321 is provided at the second end of the movable member 3 in the first direction. The notch 321 includes a notch vertical surface 3211 and a notch inclined surface 3212 connected to each other. The notch vertical surface 3211 is connected to the axial end surface of the second end of the movable member 3 at a right angle. The notch inclined surface 3212 is connected to the axial end surface of the second end of the movable member 3 at a second inclined angle.

[0076] Among them, the first inclination angle and the second inclination angle have the same inclination angle; the notch vertical surface 3211 cooperates with the block vertical surface 2211 in the circumferential direction, and the notch inclined surface 3212 cooperates with the block inclined surface 2212 in the first direction and the circumferential direction.

[0077] In this embodiment, the design of the block 221 in the fixed structure 22 and the notch 321 in the movable structure 32 of the positioning component 100 cleverly combines the guiding function of the block inclined surface 2212 and the notch inclined surface 3212, and the blocking and anti-rotation function of the block vertical surface 2211 and the notch vertical surface 3211.

[0078] The inclined surface 2212 of the block 221 and the inclined surface 3212 of the notch 321 play a key guiding role when combined, ensuring that the movable member 3 can move smoothly and accurately along the preset inclined path to the corresponding position of the fixed member 2. This design not only reduces friction and misalignment, but also provides a clear guide, allowing the movable member 3 to rest stably on the fixed member 2.

[0079] At the same time, the vertical surface 2211 of the block 221 and the vertical surface 3211 of the notch 321 act as a barrier, preventing the movable member 3 from rotating after being axially positioned. This vertical surface barrier ensures that the movable member 3 is fixed on the fixed member 2 and prevents the connection from being unstable due to rotation.

[0080] Please refer to Figure 6 , Figure 6 Schematic diagram of the distribution of the movable structure in the circumferential direction of the movable part provided in an embodiment of the present application.

[0081] like Figure 6 As shown, the distribution of the movable structure 32 on the movable part 3 is illustrated; in addition, the fixed structure 22 and the movable structure 32 have a corresponding positional relationship, so the distribution of the fixed structure 22 on the fixed part 2 is the same as that of the fixed structure 22 on the fixed part 2. Figure 6 The distribution is similar.

[0082] In some embodiments, the number of the fixed structure 22 and the movable structure 32 are both set to multiple;

[0083] In a circumferential direction of the fixing member 2 perpendicular to the first direction, the plurality of fixing structures 22 are evenly distributed at first intervals;

[0084] In a circumferential direction of the movable member 3 perpendicular to the first direction, the plurality of movable structures 32 are evenly distributed at second intervals;

[0085] The first interval and the second interval have a straight interval angle.

[0086] In this embodiment, the positioning component 100 is designed with multiple fixed structures 22 and movable structures 32 to improve its overall connection stability and adaptability. These structures are evenly distributed on the fixed part 2 and the movable part 3, respectively, along the circumferential direction perpendicular to the first direction.

[0087] Specifically, the fixed structures 22 are evenly distributed at a first interval on the fixed member 2, meaning the angles between each of the locking blocks 221 are the same. This design ensures that the fixed member 2 provides uniform support and locking points in the circumferential direction. Similarly, the movable structures 32 are evenly distributed at a second interval on the movable member 3, with each of the notches 321 also maintaining the same angular spacing, corresponding to the distribution of the fixed structures 22.

[0088] Importantly, the first and second intervals have consistent angles. This design feature ensures a consistent relationship between the fixed structure 22 and the movable structure 32, ensuring that no matter how the movable member 3 rotates, it can always find the matching fixed structure 22. This consistency not only improves the flexibility of the positioning component 100, but also enhances its connection reliability in multiple directions.

[0089] Optionally, Figure 6 There are four movable structures 32 in the embodiment, and the four movable structures 32 are evenly distributed on the movable part 3 at an interval of 90°; correspondingly, the four fixed structures 22 are evenly distributed on the fixed part 2 at an interval of 90°.

[0090] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the limiting portion 12 is located on the circumferential side surface of the first end of the rod portion 11. In the radial direction of the rod portion 11 perpendicular to the first direction, the outer diameter of the limiting portion 12 is larger than the outer diameter of the circumferential side surface. The limiting portion 12 is used to cooperate with the mounting component 200 when the positioning component 100 is connected to the mounting component 200.

[0091] In this embodiment, the stopper 12 serves a dual purpose. First, it continues to perform its basic function of limiting the range of movement of the movable member 3 on the rod 11, ensuring that the movable member 3 does not exceed the predetermined position. Second, the stopper 12, with its larger radial outer diameter, achieves an interference fit with the mounting component 200.

[0092] This interference fit not only strengthens the connection between the positioning component 100 and the mounting component 200, but also significantly improves the anti-detachment performance of the entire structure. When the stopper 12 is tightly coupled with the mounting component 200, any force attempting to disengage the mounting component 200 from the positioning component 100 will encounter greater resistance because the interference force generated by the interference fit needs to be overcome.

[0093] Furthermore, the design of the retaining portion 12 also ensures a more secure connection between the positioning component 100 and the mounting component 200 during normal use and operation, reducing the risks associated with an unstable connection. This design is crucial for ensuring the safety and reliability of medical devices during clinical use, particularly in the medical device field. This enhanced connection strength and anti-detachment performance allow the positioning component 100 to remain stable under various operating conditions, providing greater safety and reliability for medical devices.

[0094] During actual use, when it is necessary to remove the mounting component 200 from the positioning component 100, the operator first needs to apply a certain force. This force must be large enough to overcome the friction and connection force generated by the interference fit between the limiting portion 12 and the mounting component 200. Once this force is successfully applied and overcomes the preset connection resistance, the mounting component 200 can begin to separate from the positioning component 100. Subsequently, the operator can continue to perform necessary screwing actions or other adjustments to complete the disassembly or further installation process of the mounting component 200. This design ensures that the mounting component 200 can only be removed after a specific force is consciously applied, thereby greatly reducing the risk of falling off due to misoperation or accidental situations.

[0095] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the movable part and the positioning rod provided in an embodiment of the present application when they are separated.

[0096] In some embodiments, the fixing member 2 and the positioning rod 1 are integrally formed.

[0097] In this embodiment, if Figure 7 As shown, the movable part 3 can be regarded as one part, the fixed part 2 and the positioning rod 1 can be regarded as one part, and the movable part 3 is installed on the whole composed of the fixed part 2 and the positioning rod 1. The advantage of doing so is that the number of parts can be reduced, the difficulty of assembly can be reduced, and the cost can be controlled.

[0098] In addition, if the positioning rod 1 is regarded as a screw, it can be seen that there is a bolt head at the second end of the screw, that is, the right end. This application does not make any special limitations on the bolt head. That is to say, whether it is a bolt head integrally formed with the positioning rod 1 or a bolt head assembled separately from the positioning rod 1, it should all fall within the scope of description of this application.

[0099] In addition, the positioning rod 1 can be solid or hollow, and both should fall within the scope of the description of this application.

[0100] Please refer to Figure 3 , Figure 3 A partial schematic diagram of the positioning rod provided in the first embodiment of the present application.

[0101] like Figure 3 As shown, in some embodiments, in the circumferential direction of the rod 11 perpendicular to the first direction, the first end of the rod 11 is provided with a continuously extending ring body 111 extending in the circumferential direction, and the limiting portion 12 is provided on the continuously extending ring body 111.

[0102] In this embodiment, the design of the rod 11 is further enhanced by providing a continuously extending ring 111 in a circumferential direction perpendicular to the first direction. This not only provides additional structural support for the rod 11, but also creates an ideal platform for the positioning of the stopper 12. The position limiter 12 is located on the continuously extending ring 111. This layout enables the position limiter 12 to perform its function more effectively.

[0103] The design of the continuously extending ring body 111 allows the retaining portion 12 to evenly distribute its retaining effect throughout the entire circumference. This helps to more evenly withstand and transmit force, reduce local stress concentration, and thus improve the durability and reliability of the positioning component 100. Furthermore, this arrangement of the retaining portion 12 also means that it can provide additional anti-slip performance through an interference fit during connection with the mounting component 200.

[0104] Please refer to Figure 4 , Figure 4 A partial schematic diagram of the positioning rod provided in the second embodiment of the present application.

[0105] like Figure 4 As shown, in the circumferential direction of the rod 11 perpendicular to the first direction, the first end of the rod 11 is provided with a plurality of extension monomers 112 spaced apart in the circumferential direction, and the limiting portion 12 is provided on the plurality of extension monomers 112 .

[0106] In this embodiment, the design of the rod 11 employs an innovative approach to optimize structure and performance. Rather than a continuous extended ring, the first end of the rod 11, along its circumference perpendicular to the first direction, is provided with a plurality of spaced-apart extended units 112. This design not only reduces material usage and overall weight, but also maintains sufficient structural strength and stability.

[0107] The positioning members 12 are arranged on these extension units 112. This arrangement allows the positioning members 12 to effectively position and restrict the circumference. Furthermore, the spacing of the extension units 112 reduces material requirements, thereby reducing weight. This design also helps reduce production costs by reducing material consumption during the manufacturing process.

[0108] Furthermore, by spacing the extension units 112, the connection force between the stopper 12 and the mounting member 200 can be adjusted and controlled. This design allows for an appropriate interference fit without overly relying on material thickness, thereby maintaining connection strength while reducing the force required for installation and removal. This makes the connection and separation process easier while still ensuring sufficient anti-detachment performance.

[0109] Please refer to Figure 5 , Figure 5 A partial schematic diagram of a positioning rod provided in the third embodiment of the present application.

[0110] like Figure 5 As shown, in some embodiments, in the circumferential direction of the rod 11 perpendicular to the first direction, the limiting portion 12 includes a plurality of protruding units 121 spaced apart along the circumferential direction at the first end of the rod 11 .

[0111] In this embodiment, the rod 11 is designed using an economical and efficient strategy, by providing a plurality of protruding units 121 spaced apart on a continuously extending ring 111 to form the stopper 12. This design approach directly responds to the needs of reducing material usage, reducing weight, and adjusting connection force.

[0112] The raised elements 121 are evenly spaced along the circumference, reducing material usage without sacrificing structural integrity. Because the raised elements 121 provide additional support and restraint only where needed, this design effectively reduces overall component weight, which is particularly important for portable or weight-sensitive applications.

[0113] At the same time, the design of the protrusions 121 allows for fine-tuning of the connection force between the stopper 12 and the mounting member 200. By controlling the size, shape, and spacing of the protrusions 121, the degree of interference fit can be precisely set, thereby achieving appropriate connection strength and anti-slip performance without overly relying on material thickness.

[0114] Please continue to refer to Figures 3 to 5 , taking the continuously extended ring body 111 and the annular limiting portion 12 as the first solution, the extended monomer 112 and the protruding monomer 121 as the second solution, and the continuously extended ring body 111 and the protruding monomer 121 as the third solution, the connection strength between the positioning component 100 and the mounting component 200 is the first solution, the third solution and the second solution from high to low. Therefore, the anti-detachment strength of the first solution is the first, the anti-detachment strength of the third solution is the second, and the anti-detachment strength of the second solution is the last.

[0115] It should be noted that the circumferential direction of the rod portion 11 is perpendicular to the first direction, and the limiting portion 12 has various shapes in the cross section perpendicular to the circumferential direction to adapt to different application requirements and provide specific functional characteristics.

[0116] Optionally, the shape of the limiting portion 12 can be selected to be semicircular or triangular, and each shape has its own unique advantages and uses.

[0117] Choosing a semicircular cross-section for the stopper 12 provides a smooth profile, which helps reduce stress concentration when in contact with the mounting component 200 and also facilitates smooth sliding or rolling of the mounting component 200 along the edge of the stopper 12. The semicircular design may also help achieve smoother force distribution, thereby reducing local stress points during the connection process.

[0118] On the other hand, the triangular cross-section of the stopper 12 provides greater structural rigidity, which can provide additional stability in applications that need to bear large loads or in limited space. The sharp apex of the triangle can serve as a positioning point to provide precise positioning and fixation, while its straight edges may help achieve more direct force transmission.

[0119] In some cases, first thread structure 21 and second thread structure 31 are double-thread helices.

[0120] In this embodiment, the double-thread helical design provides a tighter thread pitch and higher connection strength, while allowing for smoother screwing in and out. The double-thread helical design also helps to disperse force, reduce wear, and improve the overall durability and reliability of the positioning component 100.

[0121] Please refer to Figure 8 , Figure 8 A schematic diagram of the installation components provided in an embodiment of the present application.

[0122] The present application also provides a mounting component 200, comprising:

[0123] The mounting sleeve 4 has an at least partial opening 41 formed therein for accommodating the positioning component 100 . A third threaded structure 42 is provided inside the mounting sleeve 4 . The third threaded structure 42 is used to connect to the first threaded structure 21 and / or the second threaded structure 31 .

[0124] In this embodiment, this design allows the mounting member 200 to be tightly coupled to the positioning member 100 via a threaded connection, providing a stable and reliable connection. The presence of the third thread structure 42 ensures that the mounting sleeve 4 can precisely mate with the positioning member 100, thereby achieving a high degree of stability and safety in applications such as medical devices.

[0125] In some embodiments, a matching structure 43 is further provided inside the mounting sleeve 4 , and the matching structure 43 is used for interference fit with the limiting portion 12 .

[0126] In this embodiment, in addition to the third threaded structure 42, the interior of the mounting sleeve 4 also includes a specially designed mating structure 43. The primary function of this mating structure 43 is to achieve an interference fit with the stopper 12 of the positioning component 100. This design ensures that the connection between the mounting sleeve 4 and the positioning component 100 not only relies on a threaded connection but also enhances mechanical tightness and stability through the internal mating structure 43.

[0127] The interference fit between the mating structure 43 and the stopper 12 means that during installation, the mating structure 43 will slightly enter the shape of the stopper 12, thereby providing an additional fixing effect. This mating method helps to improve the connection rigidity between the mounting component 200 and the positioning component 100, and reduces relative movement or separation caused by external forces.

[0128] Furthermore, the design of the mating structure 43 can be adjusted as needed to accommodate different sizes or shapes of the retaining portion 12, thereby providing a customized connection solution. This flexibility enables the mounting component 200 to adapt to a wider range of application scenarios, particularly in the medical device field where connection stability and security are strictly required.

[0129] Alternatively, as Figure 8 As shown, the matching structure 43 is a matching ring extending in the circumferential direction inside the mounting sleeve 4 .

[0130] Please refer to Figure 9 , Figure 9 A schematic diagram of an installation component provided in another embodiment of the present application.

[0131] Alternatively, as Figure 9 As shown, the matching structure 43 adopts linear ribs extending in the first direction inside the installation sleeve 4 , and there are multiple linear ribs, which are distributed in the circumferential direction inside the installation sleeve 4 .

[0132] In some cases, third thread structure 42 is a double-start helix.

[0133] In this embodiment, the double-thread helical design provides a tighter thread pitch and higher connection strength, while allowing for smoother screwing in and out. The double-thread helical design also helps to disperse force, reduce wear, and improve the overall durability and reliability of the mounting component 200.

[0134] The present application also provides a mounting assembly, comprising a positioning component 100 and a mounting component 200, wherein the mounting component 200 is connected to the positioning component 100;

[0135] The positioning component 100 is the aforementioned positioning component 100 , and the installation component 200 is the aforementioned installation component 200 .
