Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a dust cover fixing device for protecting the springs of an automobile suspension system. Background Technology

[0002] Shock absorbers in a car's suspension system are usually connected via hydraulic rods, and springs are then installed on the outside of the hydraulic rods for damping. However, because the hydraulic rods are located on the car's chassis, dust and mud generated during driving can adhere to the hydraulic rods, affecting their extension and contraction efficiency. Therefore, a dust cover needs to be installed inside the spring and outside the axle for protection.

[0003] However, existing dust covers are usually secured at the end with cable ties during installation. This method is relatively simple and cannot effectively limit the dust cover's movement. The dust cover can easily rotate outside the pivot, causing stress changes and making the dust cover prone to breakage. To address this issue, we propose a dust cover fixing device for protecting automotive suspension system springs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a dust cover fixing device for protecting the springs of an automotive suspension system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust cover fixing device for protecting automotive suspension system springs includes a spring dust cover. The upper and lower ends of the spring dust cover are provided with mounting seats. The mounting seats are provided with mounting grooves on both sides of their ends. The mounting grooves are provided with mounting rings. The mounting rings are semi-circular. Two sets of mounting rings are wrapped around the outer wall of the ends of the spring dust cover. One set of mounting rings is provided with a connecting seat at its end, and the other set of mounting rings is provided with a limiting seat at its end.

[0007] The two sets of mounting rings can be brought close together to clamp and fix both ends of the spring dust cover, making the installation of the spring dust cover more convenient.

[0008] Preferably, the inner wall of the mounting ring is provided with a mounting groove, and the mounting groove is serrated.

[0009] The mounting slot can press and fix the end of the spring dust cover, thereby preventing the spring dust cover from rotating and loosening between it and the mounting ring.

[0010] Preferably, a fixing groove is provided at the middle position of the side wall of the mounting ring, and a rubber pad is placed inside the fixing groove;

[0011] The ends of the spring dust cover can be further limited by rubber pads, resulting in better stability after installation.

[0012] Preferably, the connecting seat is U-shaped, a rotating shaft is movably mounted inside the connecting seat, a rotating screw is movably mounted at the end of the rotating shaft, the limiting seat is U-shaped, and the rotating screw is adapted to the limiting seat;

[0013] When the two sets of mounting rings approach each other, the rotating screw is locked inside the limiting seat, thereby connecting and bringing the ends of the mounting rings closer together, thus limiting the proximity of the mounting rings and fixing them in place.

[0014] Preferably, a limiting screw sleeve is sleeved on the outside of the limiting seat, and the limiting screw sleeve is in contact with the side wall of the limiting seat;

[0015] The mounting ring can be fixed by rotating the limiting sleeve, which will press against the side wall of the limiting seat.

[0016] Preferably, the limiting screw sleeve is hexagonal, and limiting slots are provided on both sides of the side wall of the limiting seat, with the diagonal of the limiting screw sleeve matching the limiting slots.

[0017] This allows the limiting sleeve to be locked inside the limiting slot, thus enabling the rotating screw to drive the limiting sleeve to perform better compression and limiting.

[0018] Preferably, the end of the rotating screw is provided with a rotating seat, and the end of the rotating seat is provided with a hexagonal slot;

[0019] A tool can be inserted into the groove at the end of the rotating seat, thereby causing the tool to drive the rotating seat and the rotating screw to rotate, making the rotation of the rotating screw more convenient.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model can compress the outer wall of the spring dust cover by rotating the mounting ring, and then compress the side wall of the spring dust cover by the mounting slot, so that the spring dust cover cannot rotate. Then, the rubber pad makes the stability of the spring dust cover better, thereby reducing the stress change of the spring dust cover and avoiding the spring dust cover from breaking, thus making the service life of the spring dust cover longer.

[0022] 2. This utility model allows the screw to rotate and lock into the inside of the limiting seat, thereby causing the limiting screw sleeve to embed into the inside of the limiting slot. By rotating the rotating seat, the limiting screw sleeve can be moved, which in turn causes the limiting screw sleeve to press against the limiting seat, so that the mounting rings can be connected and tightened, making the installation of the spring dust cover more convenient.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-4 The invention relates to a dust cover fixing device for protecting automotive suspension system springs. Mounting seats 2 are fixedly installed on the upper and lower sides of the spring dust cover 1. Mounting slots 3 are formed on both sides of each mounting seat 2. A mounting ring 4 is then installed inside the mounting slots 3 via a rotating shaft. The mounting ring 4 is sleeved on the outside of the spring dust cover 1. Multiple sets of mounting grooves 5 are evenly formed on the inner wall of the mounting ring 4. A fixing groove 6 is formed in the middle of the side wall of the mounting ring 4. The fixing groove 6 is filled with a rubber pad 7. Two sets of mounting rings 4 are provided, forming a complete ring. A connecting seat 8 is fixedly installed at the end of one set of mounting rings 4, while a limiting seat 11 is fixedly installed at the end of the other set of mounting rings 4.

[0030] For a detailed description of the mounting ring 4 in this embodiment, please refer to [link / reference]. Figure 3and Figure 4 A rotating shaft 9 is movably mounted inside the connecting seat 8 via a rotating shaft. A rotating screw 10 is then movably mounted at the end of the rotating shaft 9. A rotating seat 12 is fixedly mounted at the end of the rotating screw 10. A groove is provided at the end of the limiting seat 11 so that the groove on the limiting seat 11 matches the rotating screw 10. A limiting screw sleeve 13 is then sleeved on the outside of the rotating screw 10. The limiting screw sleeve 13 is hexagonal. A limiting slot 14 is provided on the side wall of the limiting seat 11. The limiting slot 14 matches the diagonal of the limiting screw sleeve 13.

[0031] Working principle: When using this utility model, during installation, rotating the mounting ring 4 causes the rubber pad 7 and mounting groove 5 to squeeze both ends of the spring dust cover 1, thereby increasing the sealing and installation limiting effect. Then, rotating the rotating shaft 9 causes the rotating screw 10 to be locked inside the rotating screw 10. Then, rotating the limiting screw sleeve 13 causes the end of the limiting screw sleeve 13 to be diagonally locked inside the limiting groove 14. At this time, rotating the rotating seat 12 drives the limiting screw sleeve 13 to move, thereby bringing the ends of the two sets of mounting rings 4 closer together to complete the compression and fixation, thus making the sealing and stability of the spring dust cover 1 better after installation.
