Description

Technical Field

[0001] The utility model relates to the technical field of locking washers, in particular to a locking washers with an anti-loosening function. Background Art

[0002] Bolts are a common structure for fixing metal parts together. During use, the bolt can be passed through an opening on a metal part and then inserted into a threaded hole on another metal part. The threads are engaged with each other by tightening, thereby achieving fixing. For such structures, the reliability of bolt tightening needs to be enhanced, especially in a vibrating environment. It is necessary to prevent the bolt from rotating relative to the threaded hole due to vibration and dynamic load, causing the bolt to loosen or even fall off, resulting in the separation of metal parts and causing various faults and safety hazards.

[0003] In order to increase the contact area between the nut of the bolt and the metal parts, a gasket can be placed on the outer sleeve of the screw below the nut. During the tightening of the bolt, the nut indirectly contacts the metal parts through the gasket. However, the height of the existing gaskets is usually fixed when in use, and the height of the gasket cannot be adjusted according to the installation requirements. Therefore, the staff needs to find some gaskets with suitable height for installation and use, which is inconvenient. For this reason, we propose a locking gasket with anti-loosening function.
