AI Technical Summary
The existing separate design of the nut and metal plate is prone to loss and has poor anti-loosening effect, which cannot meet the connection reliability requirements of complex working conditions such as vibration and high temperature.
A locking nut with a metal plate is designed. By setting an annular groove and a retaining ring on the nut body, and combining the structure of the metal plate and the slot, a stable connection between the washer and the nut is achieved. After tightening, the rotation of the nut is restricted by the metal plate, thereby improving the anti-loosening effect.
It achieves a stable connection between the nut and the metal plate, preventing loss and significantly improving the anti-loosening effect, making it suitable for complex working conditions such as vibration and high temperature.
