Description

Technical Field

[0002] Serrated washers are divided into internal serrated locking washers and external serrated locking washers. Their functions are similar to those of spring washers and can lock and prevent loosening. The internal serrated locking washer is a separate annular washer with an offset opening. When a wrench is used to tighten the nut, the serrated teeth of the offset opening will be embedded in the surface of the workpiece, preventing the nut from loosening. External serrated washers are often used in places where connecting parts are prone to loosening, and are mostly used under bolt heads and nuts to prevent connecting parts from loosening or displacement.

[0003] The existing serrated gasket changes the working position of the vibration to the middle position of the double-layer gasket, causing a certain degree of wear on the upper and lower parts of the gasket. Secondly, in a high vibration environment, the serrated gasket has a simple structure and limited function and cannot provide a good anti-loosening effect on the mechanism. Therefore, the utility model provides a serrated gasket to solve the problems raised in the above background technology. Utility Model Content
