Description

Technical Field

[0001] This invention relates to the field of pipe connection device technology, and in particular to a plug-in self-locking snap ring type pipe connection structure. Background Technology

[0002] In various fluid transport systems, the reliability of pipe connection structures is crucial. Traditional pipe connection structures often focus only on preventing detachment, neglecting to ensure proper sealing. For example, CN103759086A, entitled "Fluid Pipe Connection Assembly," while solving the problem of protecting the pipe's front end from excessive deformation during connection, suffers from pipe oscillation or rotation in high-frequency vibration environments. This not only increases the risk of pipe detachment but also leads to leaks due to relative movement at the connection points, causing safety hazards and economic losses. These shortcomings of traditional pipe connection structures are particularly pronounced in fields with high sealing requirements, such as chemical and hydraulic systems, making them unsuitable for practical applications. Summary of the Invention

[0003] This invention addresses the problems of pipe detachment and inadequate sealing in existing pipe connection structures by providing a plug-in self-locking spring-loaded pipe connection structure. This structure effectively restricts pipe rotation and reduces the risk of detachment or leakage caused by pipe oscillation or rotation in high-frequency vibration environments, thus effectively solving the problems mentioned in the background art.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows:

[0005] A plug-in self-locking spring-loaded pipe connection structure includes a plug-in base and a plug tube. The plug-in base is internally equipped with a push-off component, a spring-loaded ring, a sealing ring, and a sealing reinforcement component. A groove is formed on the outer surface of the plug tube to mate with the spring-loaded ring. When the plug tube is inserted into the plug-in base, the groove and the spring-loaded ring prevent the plug tube from detaching from the plug-in base. When the push-off component moves downwards, the spring-loaded ring disengages from the groove. The sealing reinforcement component includes a retaining ring with multiple conical spring pieces. Each conical spring piece is fitted with a sealing gasket that mates with the plug tube. The sealing reinforcement component also includes multiple arc-shaped clamps. A rotatable drive shaft is internally located within the plug-in base. When the drive shaft rotates, it causes the conical spring pieces to move outwards, causing the sealing gasket to press tightly against the inner wall of the plug tube. When the drive shaft rotates, it also causes the multiple arc-shaped clamps to move inwards, clamping and fixing the plug tube.

[0006] The push-off assembly includes a connecting cylinder that is slidably connected to the inner wall of the plug-in seat. The lower end of the connecting cylinder is provided with a tapered opening that mates with the spring tooth ring, and the upper end of the connecting cylinder is provided with a push handle.

[0007] The elastic tooth ring includes a support ring, and the inner wall of the support ring is provided with multiple elastic teeth.

[0008] The sealing and reinforcing assembly also includes a threaded cylinder that can move up and down. Multiple short connecting rods that are evenly distributed and inclined to the outer side of the upper end are hinged to the outer surface of the threaded cylinder. Conical springs are fixed to the upper surface of the retaining ring, and the upper ends of the short connecting rods are hinged to the corresponding conical springs.

[0009] A cross is fixed to the lower end of the outer surface of the threaded cylinder. The cross is slidably connected to the inner wall of the plug seat. An extension rod is provided at the outer end of the cross. A third sliding pin is provided on the inner wall of the extension rod. A side seat is provided at the outer end of the arc-shaped clamp plate and is slidably connected to the plug seat. A third inclined groove is provided on the side seat to cooperate with the third sliding pin.

[0010] A cross seat is fixedly connected to the inner wall of the connector, and a drive shaft is rotatably connected to the inner wall of the cross seat. A second bevel gear is fixedly connected to the outer surface of the drive shaft, and a first bevel gear meshes with the outer surface of the second bevel gear. A handle is coaxially fixedly connected to one side of the first bevel gear.

[0011] The upper surface of the drive shaft is provided with two incompletely threaded rods that can move and cooperate with the threaded cylinder.

[0012] The inner wall of the connector is provided with a support, and a movable first guide plate is slidably connected to one end face of the support. A push rod is slidably connected to the inner wall of the drive shaft. One end of the push rod is rotatably connected to the first guide plate, and the other end of the push rod is fixedly connected to a second guide plate. The inner ends of the two incomplete threaded rods are provided with second sliding pins. The two end faces of the second guide plate are provided with second inclined grooves that cooperate with the second sliding pins.

[0013] The inner wall of the drive shaft is slidably connected to a top plate that is fixed to the push rod, and the inner wall of the drive shaft is also provided with a first spring that cooperates with the top plate.

[0014] A bracket is fixedly connected to the support, and a long guide rod is provided on the inner wall of the bracket. A U-shaped seat is fixedly connected to one end of the long guide rod, and a wristband is fixedly connected to the other end of the long guide rod. Two first sliding pins are fixedly connected to the inner wall of the U-shaped seat. A first inclined groove that cooperates with the first sliding pin is opened on both sides of the first guide plate.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] In use, when the insertion tube is inserted into the bottom of the connector and the slot meets the spring tooth ring, the spring tooth ring engages with the slot, restricting the upward movement of the insertion tube and preventing it from disengaging from the connector. When disassembly is required, the push-off assembly moves downward, disengaging the spring tooth ring from the slot, allowing the insertion tube to move upward and disengage from the connector for disassembly. When the insertion tube is inserted into the bottom of the connector, the bottom end of the insertion tube contacts the retaining ring. Multiple conical springs and a sealing gasket, when the drive shaft rotates, move the conical springs outward, squeezing the sealing gasket and ensuring it adheres tightly to the inner wall of the insertion tube, providing a secondary seal for the connection between the insertion tube and the connector, thus improving the sealing effect. Even when the insertion tube interface is uneven, a good sealing effect is still ensured, fundamentally solving the sealing problems caused by the interface plane issue in traditional connection methods. The design addresses the challenge of sealing failure. When the drive shaft rotates, multiple arc-shaped clamps move inwards, clamping and fixing the outer surface of the insertion tube, restricting its rotation, and further securing it, thus improving connection performance. Compared to traditional structures, the self-locking snap ring pipe connection structure offers significant advantages, effectively limiting pipe rotation and further solidifying the pipe. This significantly reduces the risk of pipe detachment or leakage due to oscillation or rotation in high-frequency vibration environments, enhancing the overall stability of the connection structure. The structure exhibits excellent sealing performance; even with irregular pipe ends, the sealing effect remains unaffected, effectively preventing leakage hazards caused by end issues and enhancing connection reliability. Installation and operation are convenient, and it maintains good connection performance under complex working conditions, broadening the applicability of pipe connection structures.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figures 1-8 As shown, this invention provides a self-locking snap ring type pipe connection structure, including a plug-in seat 1 and a plug tube 2. The plug-in seat 1 is internally provided with a push-off component, a spring tooth ring 7, a sealing ring 39, and a sealing reinforcement component. The outer surface of the plug tube 2 is provided with a groove 6 that mates with the spring tooth ring 7. When the plug tube 2 is inserted into the plug-in seat 1, the groove 6 and the spring tooth ring 7 cooperate to prevent the plug tube 2 from falling off the plug-in seat 1. When the push-off component moves downward, it can disengage the spring tooth ring 7 from the groove 6. The sealing reinforcement component is also provided. The assembly includes a retaining ring 28, on which multiple conical spring pieces 29 are provided. A sealing gasket 30 that mates with the insertion tube 2 is fitted on the conical spring pieces 29. The sealing and reinforcing assembly also includes multiple arc-shaped clamping plates 36. The insertion base 1 is also provided with a rotatable drive shaft 17. When the drive shaft 17 rotates, it can form a structure in which the conical spring pieces 29 move outward to make the sealing gasket 30 tightly adhere to the inner wall of the insertion tube 2. When the drive shaft 17 rotates, it can also form a structure in which the multiple arc-shaped clamping plates 36 move inward to clamp and fix the insertion tube 2.

[0028] like Figures 1-8As shown, the connector 1 is used to install and support the entire component. Through the sealing ring 39, when the plug tube 2 is inserted into the socket, it can make tight contact with the sealing ring 39, thereby sealing the connection between the plug tube 2 and the connector 1. When the plug tube 2 is inserted to the bottom of the connector 1, causing the slot 6 to meet the spring tooth ring 7, the spring tooth ring 7 can engage with the slot 6, thus restricting the upward movement of the plug tube 2 and preventing it from disengaging from the connector 1. When it is necessary to remove the plug tube 2, by driving the push-off assembly downwards, the spring tooth ring 7 can engage with the slot 6. When the slot 6 disengages, the insertion tube 2 can move upwards and disengage from the connector 1, thus enabling disassembly. When the insertion tube 2 is inserted into the bottom of the connector 1, the bottom end of the insertion tube 2 can contact the retaining ring 28. Through the multiple conical springs 29 and the sealing gasket 30, when the drive shaft 17 rotates, the multiple conical springs 29 can move outwards, that is, the conical springs 29 can squeeze the sealing gasket 30, making the sealing gasket 30 tightly adhere to the inner wall of the insertion tube 2, thus providing a secondary seal for the connection between the insertion tube 2 and the connector 1, thereby improving the sealing effect. Furthermore, when the insertion tube 2 is connected... Despite the unevenness of the pipe opening, a good sealing effect can still be ensured, fundamentally solving the sealing failure problem caused by interface plane issues in traditional connection methods. When the drive shaft 17 rotates, multiple arc-shaped clamps 36 can move inward. When the arc-shaped clamps 36 move inward, they can clamp and fix the outer surface of the insertion tube 2, restricting the rotation of the insertion tube 2 and further clamping and fixing the insertion tube 2, improving the fixed connection performance. The plug-in self-locking spring-loaded pipe connection structure has significant advantages over traditional structures. It can effectively restrict the rotation of the pipe and further stabilize and fix the pipe, greatly reducing the risk of pipe falling off or leaking due to oscillation or rotation in high-frequency vibration environments, and improving the overall stability of the connection structure. This structure performs excellently in sealing performance. Even if the pipe end is uneven, it will not affect the sealing effect, effectively avoiding the leakage risk caused by the end problem and enhancing the reliability of the connection. Installation and operation are convenient, and it can maintain good connection performance under complex working conditions, broadening the application range of pipe connection structures.

[0029] The push-off assembly includes a connecting cylinder 3, which is slidably connected to the inner wall of the plug-in seat 1. The lower end of the connecting cylinder 3 is provided with a tapered opening 4 that cooperates with the spring tooth ring 7, and the upper end of the connecting cylinder 3 is provided with a push handle 5.

[0030] like Figures 1-4 As shown, the connecting cylinder 3 can slide up and down on the inner wall of the insertion seat 1. The push handle 5 facilitates the downward movement of the push-off assembly, namely the connecting cylinder 3 and the conical opening 4. When the push handle 5 moves downward, it can drive the connecting cylinder 3 and the conical opening 4 to move downward. When the conical opening 4 moves downward, it can drive the elastic teeth 40 of the spring tooth ring 7 to open outward, thereby disengaging the elastic teeth 40 from the slot 6. At this time, the insertion tube 2 can be disassembled.

[0031] The elastic tooth ring 7 includes a support ring, and the inner wall of the support ring is provided with a plurality of elastic teeth 40.

[0032] like Figure 4 As shown, the elastic tooth 40 is inclined inward. When the slot 6 engages with the elastic tooth 40, it can limit and prevent the insertion tube 2 from moving upward.

[0033] The sealing and reinforcing assembly also includes a threaded cylinder 31 that can move up and down. Multiple short connecting rods 32 that are evenly distributed and inclined to the outer side of the upper end are hinged on the outer surface of the threaded cylinder 31. Conical spring pieces 29 are fixed to the upper surface of the retaining ring 28, and the upper ends of the short connecting rods 32 are all hinged to the corresponding conical spring pieces 29.

[0034] like Figure 6 As shown, when the threaded cylinder 31 moves upward, it can drive the lower end of the short connecting rod 32 to move upward and the upper end of the short connecting rod 32 to move outward, which in turn drives the corresponding conical spring 29 to open outward, so that the sealing ring 39 is tightly attached to the inner wall of the insertion tube 2 for sealing; similarly, when the threaded cylinder 31 moves downward, it can drive the conical spring to move inward, that is, it no longer squeezes the sealing ring 39 and the inner wall of the insertion tube 2, at which time the insertion tube 2 can be removed and disassembled.

[0035] A cross 33 is fixedly connected to the lower end of the outer surface of the threaded cylinder 31. The cross 33 is slidably connected to the inner wall of the plug seat 1. An extension rod 34 is provided on the outer end of the cross 33. A third sliding pin 35 is provided on the inner wall of the extension rod 34. A side seat 37 is provided on the outer end of the arc-shaped clamp 36 and is slidably connected to the plug seat 1. A third inclined groove 38 is provided on the side seat 37 to cooperate with the third sliding pin 35.

[0036] like Figures 5-6 As shown, the cross 33 can slide vertically on the inner wall of the insertion seat 1, and the side seat 37 can slide horizontally or backward on the inner wall of the insertion seat 1. Even if the side seat 37 and the arc-shaped clamp 36 can slide inward or outward, when the threaded cylinder 31 moves up and down, it can drive the cross 33, the extension rod 34, and the third sliding pin 35 to move up and down. When the third sliding pin 35 moves upward, under the engagement of the third sliding pin 35 and the third inclined groove 38, it can drive the side seat 37 and the arc-shaped clamp 36 to move inward synchronously, thereby clamping and fixing the insertion tube 2. At this time, it can further fix and restrict the rotation of the insertion tube 2. When the cross 33, the extension rod 34, the third sliding pin 35, etc. move downward, it can drive the arc-shaped clamp 36 to move outward, that is, it no longer clamps and fixes the insertion tube 2. At this time, the insertion tube 2 can be disassembled.

[0037] A cross seat 18 is fixedly connected to the inner wall of the plug-in seat 1. A drive shaft 17 is rotatably connected to the inner wall of the cross seat 18. A second bevel gear 27 is fixedly connected to the outer surface of the drive shaft 17. A first bevel gear 26 meshes with the outer surface of the second bevel gear 27. A handle 8 is coaxially fixedly connected to one side of the first bevel gear 26.

[0038] like Figures 7-8 As shown, the cross seat 18 supports and limits the drive shaft 17, so that the drive shaft 17 can only rotate within the inner wall of the cross seat 18. A rotating shaft is fixedly connected to the center of the handle 8 and the first bevel gear 26, and the rotating shaft is rotatably connected to the inner wall of the plug seat 1. Under the meshing of the first bevel gear 26 and the second bevel gear 27, when the drive handle 8 is rotated, it can drive the first bevel gear 26, the second bevel gear 27, the drive shaft 17, etc. to rotate synchronously.

[0039] The upper surface of the drive shaft 17 is provided with two incompletely threaded rods 25 that can move and cooperate with the threaded cylinder 31.

[0040] like Figures 7-8 As shown, the incomplete threaded rod 25 is slidably connected to the upper surface of the drive shaft 17 and can move synchronously inward or outward. When the drive shaft 17 rotates, it can drive the incomplete threaded rod 25 to rotate. When the incomplete threaded rod 25 rotates, it can drive the threaded cylinder 31 to move upward or downward through the threaded connection with the threaded cylinder 31. When the two incomplete threaded rods 25 move inward, they can disengage from the threaded cylinder 31. At this time, the threaded cylinder 31 can be reset to its initial state under the elastic force of the conical spring plate 29. When the incomplete threaded rod 25 is engaged with the threaded cylinder 31, it has a self-locking function under the threaded connection. That is, when the drive shaft 17 and the incomplete threaded rod 25 do not rotate, the position of the threaded cylinder 31 is fixed.

[0041] The inner wall of the plug-in seat 1 is provided with a support 16. A movable first guide plate 14 is slidably connected to one end face of the support 16. A push rod 21 is slidably connected to the inner wall of the drive shaft 17. One end of the push rod 21 is rotatably connected to the first guide plate 14, and the other end of the push rod 21 is fixedly connected to a second guide plate 22. The inner ends of the two incomplete threaded rods 25 are provided with second sliding pins 24. The two end faces of the second guide plate 22 are provided with second inclined grooves 23 that cooperate with the second sliding pins 24.

[0042] like Figure 8As shown, the support 16 can be fixed to the inner wall of the insertion seat 1 and also fixed to the cross seat 18. The support 16 can support and limit the first guide plate 14. The first guide plate 14 can slide left and right on the upper surface of the support 16. The push rod 21 can slide left and right on the inner wall of the drive shaft 17. When the first guide plate 14 moves left and right, it can drive the push rod 21 and the second guide plate 22 to move left and right. Through the rotational connection between the push rod 21 and the first guide plate 14, that is, when the drive shaft 17 rotates, the push rod 21 can rotate with the drive shaft 17, and when the first guide plate 14 rotates, the push rod 21 can rotate with the drive shaft 17. When the guide plate 14 moves left and right, it can drive the top rod 21 and the second guide plate 22 to move left and right. Support seats are fixed to the inner end faces of the two incomplete threaded rods 25, and the second sliding pins 24 are fixed to the inner wall of the support seats. This is equivalent to the second sliding pins 24 being fixed to the inner end faces of the incomplete threaded rods 25. The second inclined grooves 23 on both end faces of the second guide plate 22 are centrally symmetrically arranged. When the second guide plate 22 moves to the right or left, the two incomplete threaded rods 25 can be driven to move inward or outward under the meshing of the second inclined grooves 23 and the second sliding pins 24.

[0043] The inner wall of the drive shaft 17 is slidably connected to a top plate 19 which is fixed to the top rod 21, and the inner wall of the drive shaft 17 is also provided with a first spring 20 that cooperates with the top plate 19.

[0044] like Figure 8 As shown, the top plate 19 can slide left and right on the inner wall of the drive shaft 17. One end of the first spring 20 is fixed to the inner wall of the drive shaft 17, and the other end of the first spring 20 is fixed to the top plate 19. The first spring 20 always exerts a leftward driving force on the top plate 19. Even if the push rod 21, the first guide plate 14, and the second guide plate 22 are in the leftmost position under normal conditions, and even if the incomplete thread rod 25 is in the outermost position under normal conditions, it can stably engage with the threaded cylinder 31.

[0045] A bracket 11 is fixedly connected to the support 16. A long guide rod 10 is provided on the inner wall of the bracket 11. A U-shaped seat 12 is fixedly connected to one end of the long guide rod 10, and a wristband 9 is fixedly connected to the other end of the long guide rod 10. Two first sliding pins 13 are fixedly connected to the inner wall of the U-shaped seat 12. A first inclined groove 15 that cooperates with the first sliding pin 13 is opened on both sides of the first guide plate 14.

[0046] like Figures 7-8As shown, the bracket 11 supports and limits the long guide rod 10. The long guide rod 10 passes through the bracket 11 and can slide up and down on the inner wall of the bracket 11. The long guide rod 10 also passes through the rotating shaft and can slide up and down on the inner wall of the rotating shaft. When the wristband 9, the rotating shaft, the first bevel gear 26, etc. rotate, the long guide rod 10 and the wristband 9 will not be driven to rotate. When the wristband 9 is driven to move downward, it can drive the long guide rod 10, the U-shaped seat 12, the first sliding pin 13, etc. to move downward synchronously. When the first sliding pin 13 moves downward, it engages with the first inclined groove 15. When the first guide plate 14, top rod 21, top plate 19, and second guide plate 22 move to the right, the top plate 19 compresses the first spring 20, and the second guide plate 22 drives the two incomplete threaded rods 25 to move inward, thus disengaging the incomplete threaded rods 25 from the threaded cylinder 31. At this time, the conical spring 29 can quickly return to its original position under its own elastic force. When the hand ring 9 is released, the top rod 21, top plate 19, first guide plate 14, and second guide plate 22 move to the right. Guide plate 22, long guide rod 10, hand ring 9, etc. can be reset to their initial state under the elastic force of the first spring 20, that is, the corresponding incomplete thread rod 25 moves outward again to the top and engages with the threaded seat. When the handle 8 is driven again, the threaded cylinder 31 can move left and right. When the insertion tube 2 is inserted into the bottom of the insertion seat 1, the threaded cylinder 31 is moved by controlling the drive handle 8, thereby causing multiple conical springs 29 to move outward, squeezing the sealing gasket 30 to make it tightly contact the inner wall of the insertion tube 2. At the same time, the corresponding arc-shaped clamp 36 can... The tube 2 moves inward to fix its outer surface, thus providing a secondary fixation and seal to prevent it from rotating or moving, thereby improving both sealing and fixing performance. When the tube 2 needs to be disassembled, the drive ring 9 moves inward to disengage the two incomplete threaded rods 25 from the threaded cylinder 31. At this time, under the action of the conical spring 29, the tube 2 can be reset to its initial position, and the corresponding arc-shaped clamp 36 can move outward to stop clamping the tube 2. Then, the drive handle 5 can disassemble the tube 2.

[0047] In use, when the insertion tube 2 is inserted into the bottom of the connector 1 and the slot 6 meets the spring tooth ring 7, the spring tooth ring 7 can engage with the slot 6, thus restricting the upward movement of the insertion tube 2 and preventing the insertion tube 2 from disengaging from the connector 1. When it is necessary to disassemble the insertion tube 2, by driving the push-off component to move downward, the spring tooth ring 7 can disengage from the slot 6, at which point the insertion tube 2 can move upward and disengage from the connector 1, thereby enabling disassembly. When the insertion tube 2 is inserted into the bottom of the connector 1, the insertion... The bottom end of tube 2 can contact the retaining ring 28. Through the multiple conical springs 29 and the sealing gasket 30, when the drive shaft 17 rotates, the multiple conical springs 29 can move outwards, that is, the conical springs 29 can squeeze the sealing gasket 30, making the sealing gasket 30 tightly adhere to the inner wall of the insertion tube 2, thus providing a secondary seal for the connection between the insertion tube 2 and the insertion seat 1, thereby improving the sealing effect. Furthermore, even when the interface of the insertion tube 2 has unevenness, it can still ensure a good sealing effect, fundamentally solving the problems of traditional connections. The connection method addresses the sealing failure problem caused by interface plane issues. When the drive shaft 17 rotates, multiple arc-shaped clamps 36 move inward, clamping and fixing the outer surface of the insertion tube 2, restricting its rotation, and further securing it, thus improving the connection performance. Compared with traditional structures, the plug-in self-locking spring-loaded pipe connection structure has significant advantages, effectively restricting pipe rotation and further securing the pipe, greatly reducing the risk of pipe detachment or leakage due to oscillation or rotation in high-frequency vibration environments, and improving the overall stability of the connection structure. This structure exhibits excellent sealing performance; even if the pipe ends are irregular, it will not affect the sealing effect, effectively avoiding leakage hazards caused by port issues and enhancing connection reliability. Installation and operation are convenient, and it can maintain good connection performance under complex working conditions, broadening the application range of pipe connection structures.
