AI Technical Summary

Technical Problem

Fastening bolts are prone to loosening after prolonged use or when subjected to external vibrations, leading to safety hazards. Existing technologies cannot effectively prevent loosening.

Method used

An anti-loosening fastening assembly was designed, including a nut, a bolt, an upper spring, and a bottom spring. The reverse force of the spring prevents the nut or bolt from loosening, and the friction is enhanced by setting an anti-slip pad and using glue to fix it, thereby improving the fixing effect.

Benefits of technology

It effectively prevents bolts from loosening, improves the fixing effect, has a simple structure, is easy to use, and enhances the stability and safety of the connection.
