Description
Technical Field
[0001] This utility model belongs to the field of catheters, and in particular relates to a double-ended connector and a catheter docking device. Background Technology
[0002] Conduit connectors are used to quickly connect two pipes. Compared to flange and welding repair methods, conduit connectors not only save the space, time, and money required by flange and welding methods, but also fully guarantee their quality. They are gradually replacing some traditional conduit technologies and are widely used in various industries. Conduit connection refers to connecting pre-fabricated pipe sections into a complete system according to the design drawings. Connector refers to the process of using fasteners to connect two separate profiles or parts into a complex part or component. Double-ended connectors refer to connectors that can be connected from both ends simultaneously. However, existing double-ended connectors, such as the Chinese utility model patent with application number 202421901033.9, usually have a rigid fastening effect, which can easily cause the conduit to deform and leaks after docking.
[0003] Therefore, there is an urgent need to design a double-ended connector and conduit docking device to solve the problems mentioned above. Utility Model Content
[0004] One object of the present invention is to provide a double-ended connector that, by centrally positioning the sealing module, allows the sealing module to directly act on the mating point of the conduit, thereby avoiding leakage problems after mating.
[0005] Another object of the present invention is to provide a dual-head connector in which the inclined plane driven clamping element provides a progressive clamping force that is gentler than threaded locking and reduces the risk of conduit deformation.
[0006] To achieve the above objectives, the specific technical solution of the present invention for a double-ended connector and conduit docking device is as follows:
[0007] A double-ended connector for mating conduits includes a connector body. The connector body contains a sealing module and a clamping module. The sealing module is located in the middle of the connector body and is used to seal the connection point of the mated conduits. The clamping modules are located at both ends of the connector body. Each clamping module includes a first driving member and a clamping member. The first driving member abuts against the clamping member, and the abutment position of the first driving member and the clamping member is provided with an inclined surface. The first driving member and the clamping member are movable relative to each other to clamp the clamping member onto the conduit.
[0008] Furthermore, the sealing module includes a second driving member and multiple sealing rings. A boss is provided at the middle position of the connector body. The multiple sealing rings abut against the boss and the second driving member respectively. The second driving member is used to bring the multiple sealing rings closer to each other to clamp and seal the conduit connection after docking.
[0009] Furthermore, one of the plurality of sealing rings is configured as a sealing pressure ring, and an annular pressure cavity is provided on the outer edge of the sealing pressure ring. A pressure measuring channel is provided in the middle of the connector body, and the pressure measuring channel is connected to the pressure cavity for detecting the airtightness of the sealing module.
[0010] Furthermore, the dual-head connector also includes a limiting module, which is disposed on the connector body and is used to limit the stroke and position of the first driving member and the second driving member.
[0011] Furthermore, the limiting module includes:
[0012] A first limiting component is provided, which passes through the connector body. The first driving member is provided with spaced stop blocks, and the first limiting component is disposed between the stop blocks to limit the stroke of the first driving member.
[0013] The second limiting component is inserted through the connector body. The second driving member is provided with spaced slots. The second limiting component can extend into the slots to fix the connector body and the second limiting component relative to each other.
[0014] Furthermore, the first limiting component includes a first connector and a first limiting block. The first connector passes through the connector body and is connected to the first limiting block. The first limiting block is disposed between the stop blocks to limit the stroke of the first driving member.
[0015] Furthermore, the second limiting component includes a second connector and a second limiting block. The second connector passes through the connector body and is connected to the second limiting block. An elastic element is provided between the second connector and the second limiting block. The elastic element is used to drive the second limiting block into the slot so that the connector body and the second limiting component are relatively fixed.
[0016] Furthermore, the dual-head connector also includes guide tubes disposed at both ends of the connector body. The clamping member includes a first inclined surface and a second inclined surface, the first inclined surface and the second inclined surface intersect, the first inclined surface abuts against the first driving member, the second inclined surface abuts against the guide tube, and the first driving member can move closer to or away from the guide tube so that the clamping member clamps or releases the guide tube.
[0017] Furthermore, the dual-head connector also includes a guide plate, which is circumferentially disposed outside the opening of the guide tube. Along the center of the connector body, towards the guide tube, the width of the guide plate gradually decreases.
[0018] A conduit docking device includes the aforementioned double-ended connector.
[0019] The double-ended connector of this utility model has the following advantages:
[0020] 1. By centering the sealing module, the sealing module acts directly on the connection point of the conduit, thus avoiding leakage problems after connection;
[0021] 2. The inclined plane driven clamping element provides a progressive clamping force, which is gentler than threaded locking, reduces the risk of conduit deformation, and is more adaptable to conduit docking in corrosive environments;
[0022] 3. By centering the sealing module and placing the clamping modules at both ends, the locking force is prevented from acting directly on the sealing part, thus reducing the risk of conduit deformation.
[0023] The conduit docking device of this utility model has the following advantages: the conduit docking device avoids thread corrosion by clamping with a bevel, and the sealing module resists media penetration; the pressure measuring channel dynamically maintains a seal, and the limit module prevents overpressure damage.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0033] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.
[0034] A connector is a process of using fasteners to connect two separate profiles or parts into a complex part or component. A double-ended connector is a connector that can be connected from both ends simultaneously. Current double-ended connectors typically use threaded fastening to lock the conduits on both sides. For example, Chinese utility model patent application number 202421901033.9 describes inserting the tube along the clamping space, with the locking cap moving towards the middle of the clamping tube. This causes the locking cap to drive part of the clamping tube to move towards the clamping space, thereby clamping the inner wall of the clamping tube and the outer wall of the connecting tube against the side wall of the tube, effectively fixing the tube. However, threaded pre-tightening is usually quite rigid, easily causing damage during the tube connection process, especially in underwater operations. The tubes are often corroded by seawater, making them more susceptible to direct breakage during tube replacement and connection, resulting in incalculable losses. Moreover, the aforementioned patent does not effectively seal the tube connection, making leakage at the connection point easy, leading to unsatisfactory connection results.
[0035] Therefore, there is an urgent need to design a double-ended connector and conduit docking device to solve the problems mentioned above. See the attached document for details. Figure 1 To be continued Figure 5 This invention describes a double-ended connector and a conduit docking device.
[0036] This embodiment provides a dual-head connector. Figure 1 This is a schematic diagram of the structure of the double-headed connector in this embodiment; Figure 2 This is a side view of the double-headed connector of this utility model; Figure 3 This is a cross-sectional view of the double-ended connector of this utility model during conduit docking, as shown below. Figures 1-3 As shown, the double-ended connector is used to connect the conduit 7. The double-ended connector includes a connector body 1, and a sealing module 2 and a clamping module 3 are provided inside the connector body 1. The sealing module 2 is located in the middle of the connector body 1 and is used to seal the connection of the connected conduit 7 after docking. The clamping module 3 is located at both ends of the connector body 1. The clamping module 3 includes a first driving member 31 and a clamping member 32. The first driving member 31 abuts against the clamping member 32, and the abutting position of the first driving member 31 and the clamping member 32 is provided with an inclined surface. The first driving member 31 and the clamping member 32 can move relative to each other so that the clamping member 32 clamps the conduit 7.
[0037] This dual-head connector, by centrally positioning the sealing module 2, allows it to directly act on the mating point of the conduit 7, thus avoiding leakage problems after mating. The inclined-drive clamping element 32 provides a progressive clamping force, which is gentler than threaded locking, reducing the risk of conduit 7 deformation and making it more suitable for mating conduit 7 in corrosive environments. By centrally positioning the sealing module 2 and placing the clamping modules 3 at both ends, the locking force is prevented from directly acting on the sealing area, further reducing the risk of conduit 7 deformation.
[0038] Figure 4 This is a cross-sectional view of the double-headed connector of this utility model;
[0039] Furthermore, such as Figure 3 and Figure 4 As shown, the sealing module 2 includes a second driving member 21 and multiple sealing rings 22. A boss 11 is provided at the middle position of the connector body 1. The multiple sealing rings 22 abut against the boss 11 and the second driving member 21 respectively. The second driving member 21 is used to bring the multiple sealing rings 22 closer to each other to clamp and seal the connection of the conduit 7 after docking.
[0040] Understandably, the multiple sealing rings 22 work together to form a redundant seal, maintaining sealing even if a single sealing ring 22 fails. The second drive component 21 can adjust the pressure of the sealing rings 22 to adapt to different pipe diameters or compensation needs after wear.
[0041] Figure 5 for Figure 4 A magnified view of a section at point A in the middle;
[0042] Furthermore, such as Figure 4 and Figure 5 As shown, one of the multiple sealing rings 22 is configured as a sealing pressure ring 23. An annular pressure cavity 231 is provided on the outer edge of the sealing pressure ring 23. A pressure measuring channel 232 is provided in the middle of the connector body 1. The pressure measuring channel 232 is connected to the pressure cavity 231 and is used to detect the airtightness of the sealing module 2.
[0043] It should be noted that since the conduit is usually located in the middle of the double-ended connector during docking, placing the sealing module 2 in the middle of the double-ended connector can better ensure the tightness of the docking. In addition, the middle sealing module 2, combined with the design of the annular pressure chamber 231, uses the pressure measuring channel 232 to detect the sealing performance in real time, prevent fluid leakage, and further improve the reliability of long-term underwater use.
[0044] Furthermore, such as Figure 4 As shown, the double-headed connector also includes a limiting module 4, which is disposed on the connector body 1. The limiting module 4 is used to limit the stroke and position of the first driving member 31 and the second driving member 21.
[0045] Understandably, the design of the limit module 4 can prevent the sealing ring 22 from being over-compressed or the clamping part 32 from damaging the conduit 7 due to the overtravel movement of the first drive component 31 and the second drive component 21. It can also clearly limit the adjustment range and reduce the risk of human error.
[0046] Figure 6 for Figure 5 A magnified view of a section at point B.
[0047] Furthermore, such as Figure 4 and Figure 6 As shown, the limiting module 4 includes a first limiting component 41 and a second limiting component 42. The first limiting component 41 is inserted through the connector body 1. The first driving member 31 is provided with spaced stop blocks 411. The first limiting component 41 is disposed between the stop blocks 411 to limit the stroke of the first driving member 31. The second limiting component 42 is inserted through the connector body 1. The second driving member 21 is provided with spaced slots 421. The second limiting component 42 can extend into the slots 421 to fix the connector body 1 and the second limiting component 42 relatively.
[0048] Understandably, the component design provides independent limits for the clamping and sealing functions to ensure that the two do not interfere with each other; the slot 421 structure enables the second drive component 21 to be quickly fixed, improving assembly efficiency.
[0049] Furthermore, the first limiting component 41 includes a first connector 412 and a first limiting block 413. The first connector 412 passes through the connector body 1 and is connected to the first limiting block 413. The first limiting block 413 is disposed between the stop blocks 411 to limit the stroke of the first driving component 31.
[0050] Understandably, the aforementioned relatively pure mechanical structure limiters have no risk of electronic component failure, are suitable for harsh environments, and their modular design makes it easy to replace or adjust the limit range, facilitating subsequent maintenance by staff.
[0051] Furthermore, the second limiting component 42 includes a second connector 422 and a second limiting block 423. The second connector 422 passes through the connector body 1 and is connected to the second limiting block 423. An elastic element is provided between the second connector 422 and the second limiting block 423. The elastic element is used to drive the second limiting block 423 into the slot 421 so that the connector body 1 and the second limiting component 42 are relatively fixed.
[0052] Understandably, the elastic element provides continuous pressure to ensure that the second limiting block 423 can stably fall into the slot 421 on the second driving member 21, making the second limiting block 423 and the second driving member 21 more stable after locking, and avoiding loosening caused by vibration.
[0053] Furthermore, the double-ended connector also includes guide tubes 12 disposed at both ends of the connector body 1. The clamping member 32 includes a first inclined surface 321 and a second inclined surface 322. The first inclined surface 321 and the second inclined surface 322 intersect. The first inclined surface 321 abuts against the first driving member 31, and the second inclined surface 322 abuts against the guide tube 12. The first driving member 31 can move closer to or further away from the guide tube 12 so that the clamping member 32 clamps or releases the guide tube 7.
[0054] Understandably, the double-sloping-plane design converts the axial force of the drive component into the radial clamping force of the clamping component 32, improving mechanical efficiency. The guide component ensures the linear movement of the clamping component 32, avoiding localized stress concentration caused by misalignment.
[0055] It is understood that the connector body 1 includes a connecting tube 13 and an intermediate tube 14 that are connected to each other. The two conduits 7 are connected in the connecting tube 13. The sealing module 2 is disposed in the intermediate tube 14, and the inner ring of the connecting tube 13 is provided with the aforementioned boss 11. The sealing ring 22 of the sealing module 2 abuts against the boss 11. The intermediate tube 14 is located between the guide tube 12 and the connecting tube 13, and a pressure testing channel 232 is provided on it for completing the pressure relief test.
[0056] Specifically, the double-ended connector also includes a cable support 5 and a cable routing plate 6. One of the legs of the cable support 5 is set on the intermediate tube 14, and the other is set on the connecting tube 13 connected to the same side of the intermediate tube 14, for supporting and winding the cable of the conduit 7. The cable routing plate 6 is parallel to the axis of the double-ended connector, and one end is connected to one of the legs of the cable support 5, and the other end is connected to the intermediate tube 14 away from the cable support 5. It can be understood that the parallel design of the cable routing plate 6 facilitates the routing of the cable of the conduit 7, making the whole thing neater and more standardized.
[0057] Furthermore, the double-ended connector also includes a guide plate 121, which is circumferentially disposed on the outside of the opening of the guide tube 12. Along the center of the connector body 1, the width of the guide plate 121 gradually decreases towards the guide tube 12.
[0058] Understandably, the gradient width design smoothly guides the insertion of conduit 7, reducing installation resistance. It also prevents the edge of conduit 7 from making hard contact with the connector, protecting the surface of conduit 7.
[0059] This embodiment also provides a conduit docking device, including the aforementioned double-ended connector. This conduit docking device uses a beveled clamping mechanism to prevent thread corrosion, and the sealing module 2 resists media penetration; the pressure testing channel 232 dynamically maintains a seal, and the limiting module 4 prevents damage from overpressure.
[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
