AI Technical Summary

Technical Problem

Existing nuts are prone to loosening after being impacted, causing the bolt and nut to fail in their locking and fixing function on the object.

Method used

An integrated self-locking, corrosion-resistant, high-strength nut was designed. The nut and washer are made of high-strength, corrosion-resistant materials. The washer includes an upper washer and a lower washer. The upper and lower ends of the washer form ring teeth and protrusion/groove structures, respectively. The ring teeth are in opposite directions to increase the damping effect and prevent loosening.

Benefits of technology

When the nut is subjected to severe impact, the friction is increased through the ring teeth and the protrusion/groove structure to achieve a self-locking function, prevent the nut and bolt from shaking, and maintain the locking effect.
