AI Technical Summary

Technical Problem

Existing lock cylinder mechanisms fail to prevent destructive lock bypass due to liquid infiltration causing the sliding locking pin to freeze, leading to self-lock failure, and the sealing pad's stability is compromised by poor connection with the cylinder spindle.

Method used

A lock cylinder mechanism with a protective shroud securing the sealing pad to the cylinder spindle, enhancing its stability and sealing effect, and a pusher element to disconnect drive blocks after compromise, preventing destructive lock bypass.

Benefits of technology

The mechanism effectively blocks liquid infiltration, maintains sealing pad stability, and prevents destructive lock bypass by disconnecting drive blocks, ensuring enhanced security and reliability.
