Abstract

The utility model discloses a combination bolt, which relates to an automobile component. The combination bolt comprises a hexagonal flange bolt (1), on which a screw rod (2) is disposed; a wave washer (3) is sleeved on the screw rod (2), the wave washer (3) is an annular structure with an opening, and the wave washer (3) is a wave-shaped structure along the circumferential direction. The utility model solves the problem that the existing combination bolt has poor anti-loosening performance.

Description

a combination bolt

technical field

The utility model relates to a spare part for an automobile.

Background technique

At present, the bolts used in automobiles generally adopt the structure of elastic washer combined bolts, and the edge of the elastic washer of this bolt is an inclined straight line. This kind of bolt has poor anti-loosening performance. In use, because the car is in a state of motion, the bolts will loosen after a long period of use, which can easily cause safety accidents.

Utility model content

The utility model provides a combination bolt, which solves the problem that the existing combination bolt has poor anti-loosening performance.

In order to solve the above problems, the utility model adopts the following technical scheme: a combination bolt, including a hexagonal flange bolt 1, a screw rod 2 is arranged on the hexagonal flange bolt 1; The ring structure of the opening, the wave washer 3 has a wavy structure along the circumferential direction.

The utility model can prevent the bolt from loosening during the movement of the automobile because the washer adopts a wave-shaped structure. The wave washer can enhance the anti-loosening effect of the combination bolt.
