Description

Technical Field

[0001] This utility model belongs to the field of fastener technology, specifically relating to an automotive fastener structure. Background Technology

[0002] In automotive repair, the reliability of pipe connection is directly related to the normal operation and driving safety of the vehicle. As the core component for securing pipe connections, clamps can effectively prevent pipes from loosening or leaking due to vibration, pressure fluctuations, and other factors by applying a uniform and stable clamping force to the pipe connection.

[0003] However, as the design of automotive internal piping systems becomes increasingly complex, the dimensions and specifications of these pipes exhibit significant diversity. This diversity directly leads to the need for a wide variety of clamps during maintenance. In practical applications, if an undersized clamp is used, its clamping range may not cover the effective area of ​​the pipe connection, failing to provide sufficient tightening force and achieving the desired fixation. This can result in poor clamp-to-pipe compatibility, leading to seal failure at the pipe connection, vehicle malfunctions, and potential safety hazards. Furthermore, it causes considerable inconvenience for subsequent maintenance. Therefore, a widely compatible automotive piping fastener is needed. Utility Model Content

[0004] The purpose of this invention is to provide an automotive fastener structure that addresses the problem in practical applications where undersized clamps, unable to cover the effective area of ​​the pipe connection, fail to provide sufficient fastening force and achieve the desired fixing effect. This can lead to poor compatibility between the clamp and the pipe, causing seal failure at the pipe connection, vehicle malfunctions, and potential safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive fastener structure, including a lower retaining ring, wherein the two side openings of the lower retaining ring are opposite to the two side openings of the upper retaining ring, and a rubber pad is movably installed on the annular inner wall formed by the lower retaining ring and the upper retaining ring.

[0006] Two movable columns are symmetrically welded to the outer walls of the openings on opposite sides of the lower and upper retaining rings. The two movable columns have an arc-shaped structure, and the arc of the movable columns matches the arc of the lower and upper retaining rings. A set of movable strips is also welded between the two movable columns and on one side of the lower retaining ring. One end of the movable strip is movably fitted into the upper retaining ring, and the other end of the movable strip is fixedly connected to the upper retaining ring by a locking button.

[0007] In order to allow the movable column to contract inside the upper retaining ring, thereby adjusting the inner diameter of the lower and upper retaining rings, as a preferred automotive fastener structure of this utility model, two arc-shaped grooves are evenly spaced through the outer wall of one end of the upper retaining ring, the bottom of the arc-shaped grooves is connected to the top of the through hole, and the through hole penetrates the bottom outer wall of the upper retaining ring.

[0008] The two movable columns extend through the through hole into the interior of the arc-shaped groove, and one end of the lower retaining ring and the upper retaining ring are movably connected through the movable columns, the through hole and the arc-shaped groove.

[0009] To improve the stability of the movable column when passing through the through hole and the arc groove, as a preferred embodiment of the automotive fastener structure of this utility model, a guide column is fixedly installed on the outer wall of the end connecting the through hole and the arc groove, and the interior of the guide column moves through the movable column.

[0010] In order to fix the adjusted lower and upper retaining rings, as a preferred automotive fastener structure of this utility model, grooves are provided on the outer walls of the upper retaining rings on both sides of the arc-shaped groove opening, and one end of the movable strip is movably fitted into the inside of the groove.

[0011] A set of threaded holes are evenly spaced on the inner wall of the movable strip, and the locking button passes through the movable strip and is screwed into the corresponding threaded hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] During use, the lower and upper retaining rings can be adjusted according to the required size of the automotive piping. To adjust, remove the locking button. Then pull the lower and upper retaining rings apart, causing them to move away from each other. This movement allows the movable column and movable strip to move along a fixed track on the upper retaining ring. After adjustment, pass the locking button through the movable strip and lock it into the corresponding threaded hole. This ensures the inner diameter of the lower and upper retaining rings matches the diameter of the automotive piping to be tightened. In practice, this clamp structure can accommodate various sizes of automotive piping to be tightened. This improves the convenience of parts use during maintenance and enhances the secureness and safety of the tightened connection. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 The present invention provides the following technical solution: an automotive fastener structure, including a lower retaining ring 1, the two side openings of the lower retaining ring 1 being opposite to the two side openings of the upper retaining ring 2, and a ring of rubber pads 3 being movably installed on the annular inner wall formed by the lower retaining ring 1 and the upper retaining ring 2.

[0021] The lower retaining ring 1, upper retaining ring 2, and rubber pad 3 constitute a clamp structure. In use, the clamp is placed over the automotive pipeline connection to be tightened, and then bolted to the other end of the clamp for locking. This causes the inner diameter of the clamp to contract, thus locking the automotive pipeline to the connection end. Furthermore, the rubber pad 3 protects the tightened portion, preventing damage to the automotive pipeline during the locked state.

[0022] Two movable posts 4 are symmetrically welded to the outer walls of the openings on opposite sides of the lower retaining ring 1 and the upper retaining ring 2. The two movable posts 4 have an arc-shaped structure, and the arc of the movable posts 4 matches the arc of the lower retaining ring 1 and the upper retaining ring 2. A set of movable bars 5 is also welded between the two movable posts 4 and on one side of the lower retaining ring 1. One end of the movable bar 5 is movably fitted into the upper retaining ring 2, and one end of the movable bar 5 is fixedly connected to the upper retaining ring 2 by a locking button 6.

[0023] Preferably, two arc-shaped grooves 21 are evenly spaced on the outer wall of one end of the upper retaining ring 2, the bottom of the arc-shaped grooves 21 are connected to the top of the through hole 22, and the through hole 22 penetrates the bottom outer wall of the upper retaining ring 2.

[0024] Two movable columns 4 extend through the through hole 22 into the interior of the arc-shaped groove 21, and one end of the lower retaining ring 1 and the upper retaining ring 2 are movably connected through the movable column 4, the through hole 22 and the arc-shaped groove 21.

[0025] In practical use, pulling the lower retaining ring 1 will simultaneously move the movable column 4 and the movable bar 5, which will move along the trajectory of the through hole 22 and the groove 24. In this way, the lower retaining ring 1 and the upper retaining ring 2 will not disengage from the connection structure during adjustment, thus providing convenience for subsequent re-locking.

[0026] Preferably, a guide post 23 is fixedly installed on the outer wall of the end where the through hole 22 connects with the arc groove 21, and the interior of the guide post 23 movably passes through the movable post 4.

[0027] In practical use, when the movable column 4 moves, it will move inside the guide column 23. Under the action of the guide column 23, the movable column 4 can be constrained, so that the movable column 4 remains stable in the arc groove 21.

[0028] Preferably, grooves 24 are provided on the outer wall of the upper retaining ring 2 on both sides of the opening end of the arc groove 21, and one end of the movable strip 5 is movably fitted into the inside of the groove 24;

[0029] A set of threaded holes 25 are equally spaced on the inner wall of the movable strip 5, and the locking button 6 passes through the movable strip 5 and is screwed into the corresponding threaded hole 25.

[0030] In practical use, after adjusting the distance between the lower retaining ring 1 and the upper retaining ring 2, the locking button 6 is passed through the mating hole at one end of the movable strip 5 and mated with the threaded hole 25 to lock it in place. In this way, the lower retaining ring 1 and the upper retaining ring 2 can be kept at the adjusted size, thus facilitating subsequent locking operations.

[0031] Working principle: During use, the lower retaining ring 1 and the upper retaining ring 2 can be adjusted according to the required size of the automotive piping. To adjust, remove the locking button 6. Then pull the lower retaining ring 1 and the upper retaining ring 2, causing them to move away from each other.

[0032] When the lower retaining ring 1 and the upper retaining ring 2 move away from each other, the movable column 4 and the movable bar 5 will move along a fixed track on the upper retaining ring 2. After adjustment, the locking button 6 is passed through the movable bar 5 and locked into the corresponding threaded hole 25. In this way, the inner diameter of the lower retaining ring 1 and the upper retaining ring 2 will be adapted to the diameter of the automotive locking pipe that needs to be tightened. In actual use, the clamp of this structure can be adapted to various specifications of automotive pipes to be tightened.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
