Description

Technical Field

[0001] The utility model relates to the field of anti-loosening bolts, in particular to a high-strength anti-loosening bolt. Background Technique

[0002] An anti-loosening bolt is a fastener specifically designed to prevent the bolt from loosening during use due to vibration, impact or other factors. Bolt loosening may cause equipment vibration, component damage, or even personal injury. Therefore, anti-loosening bolts are of great significance in various engineering applications.

[0003] In the prior art, when the device is in use, the bolt and the nut are cooperated to fasten and connect two parts with through holes. This connection form is called bolt connection. If the nut is screwed off the bolt, the two parts can be disassembled. When the bolt is fixed, since some devices may vibrate during use, long-term vibration will cause the bolt to rotate in the reverse direction, resulting in bolt loosening and affecting its fixing effect and the normal operation of the equipment. Therefore, it is necessary to improve a high-strength anti-loosening bolt to solve the above problems. Summary of the Utility Model
