Background
In the field of mechanical engineering, nuts are widely used as a common fastener for connecting various devices and structures. However, in practical application scenarios, nuts face a number of challenges. During operation of the device, the device is often affected by vibration, impact, temperature changes and other factors. These factors can cause the nut to come loose, thereby compromising the robustness of the device connection. Once the nut is loosened, a serious series of consequences may occur. In some critical equipment, loosening of nuts may even lead to equipment failure, production stagnation, and even endangerment of personnel life.
The traditional nut anti-loosening method mainly uses a spring washer, but the spring washer may lose elasticity after long-term use, and the anti-loosening effect is poor, so that the assembly requirement cannot be met.
Based on the above situation, the utility model provides a nut anti-loosening locking device, which can effectively solve the above problems.
