Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and more specifically discloses a structure for preventing an eccentric bolt from rotating. Background Technique

[0002] In the existing vehicle models, the frame swing arm and the vehicle body bracket are connected by an eccentric bolt. Due to the position requirements of the eccentric bolt, attention must be paid at all times during the tightening process to avoid situations where the position does not meet the requirements. The existing technology is to clamp the end of the eccentric bolt with a tool and then tighten the installation nut. However, in the existing vehicle models, the structure is inconvenient for personnel to operate, and there is a phenomenon of rotation together, and the position cannot be guaranteed. Content of the Utility Model

[0003] The main technical problem to be solved by the utility model is to provide a structure for preventing an eccentric bolt from rotating, which can solve the problems of inconvenient operation for personnel and the inability to guarantee the position due to the phenomenon of rotation together.

[0004] To solve the above technical problem, according to one aspect of the utility model, more specifically, it is a structure for preventing an eccentric bolt from rotating, including a vehicle body bracket body. A pair of vehicle body bracket limiting structures are symmetrically fixed below the left and right outer walls of the vehicle body bracket body. Installation holes are provided in the left and right outer walls of the vehicle body bracket body in the middle of each pair of the vehicle body bracket limiting structures. An eccentric bolt is commonly penetrated through the two installation holes. An eccentric gasket is penetrated through the left outer wall of the eccentric bolt on the left side of the vehicle body bracket body. An installation nut is screwed on the left side of the eccentric gasket on the left outer wall of the eccentric bolt.

[0005] Furthermore, the upper and lower outer walls of the eccentric gasket are in contact with the opposite surfaces of the left pair of the limiting structures, and the upper and lower sides of the right outer wall of the eccentric bolt are in contact with the opposite surfaces of the right pair of the limiting structures.

[0006] Furthermore, the distance between each pair of the limiting structures is greater than the diameter of the installation hole.

[0007] Furthermore, the positions of the two installation holes correspond to each other.

[0008] The beneficial effect of the structure for preventing an eccentric bolt from rotating of the utility model is as follows: This limiting structure includes a vehicle body bracket body and vehicle body bracket limiting structures and an eccentric bolt. The vehicle body bracket body and the vehicle body bracket limiting structures are integrated. The eccentric bolt is placed and penetrated through the two installation holes of the vehicle body bracket. The eccentric gasket is penetrated through the eccentric bolt and placed at the corresponding position of the vehicle body bracket body. The eccentric bolt and the eccentric gasket are both placed in the middle of the vehicle body bracket limiting structures. After the installation nut is tightened, the eccentric bolt and the eccentric gasket are both fixed in position by the vehicle body bracket limiting structures, so as to ensure that the eccentric bolt will not rotate during use.

[0015] The present utility model will be described in detail below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0016] According to one aspect of the present utility model, as Figures 1-4 shown, a structure for preventing the rotation of an eccentric bolt is provided, including a body bracket body 1. A pair of body bracket limit structures 2 are symmetrically fixed below the left and right outer walls of the body bracket body 1. Mounting holes 6 are provided in the left and right outer walls of the body bracket body 1 in the middle of each pair of body bracket limit structures 2. An eccentric bolt 3 is commonly passed through the two mounting holes 6. An eccentric gasket 4 is passed through the outer wall of the left side of the eccentric bolt 3 on the left side of the body bracket body 1. A mounting nut 5 is screwed on the left side of the eccentric gasket 4 on the left side of the outer wall of the eccentric bolt 3. During installation, the eccentric bolt 3 is placed and passed through the two mounting holes 6 of the body bracket body 1. The eccentric gasket 4 is passed through the eccentric bolt 3 and placed at the corresponding position of the body bracket body 1. The eccentric bolt 3 and the eccentric gasket 4 are both placed in the middle of the limit structure 2 of the body bracket body 1. After tightening the mounting nut 5, the eccentric bolt 3 and the eccentric gasket 4 are both fixed in position by the limit structure 2 of the body bracket body 1, thereby ensuring that the eccentric bolt 3 will not rotate during use.

[0017] The upper and lower outer walls of the eccentric gasket 4 are in contact with the opposite surfaces of the left pair of limit structures 2, and the upper and lower sides of the right outer wall of the eccentric bolt 3 are in contact with the opposite surfaces of the right pair of limit structures 2, ensuring that the limit structure 2 can completely fix the eccentric bolt 3 and the eccentric gasket 4.

[0018] The distance between each pair of limit structures 2 is greater than the diameter of the mounting hole 6, ensuring that the mounting hole 6 can limit the eccentric bolt 3 and the eccentric gasket 4.

[0019] The positions of the two mounting holes 6 correspond to each other, ensuring that the eccentric bolt 3 can pass through the interior of the mounting hole 6.

[0020] Certainly, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the substantial scope of the present utility model also fall within the protection scope of the present utility model.
