ANTI-SHOCK MECHANISM FOR AN ELECTRONIC LOCK

摘要

The present anti-shock mechanism for an electronic lock (10) is designed to limit displacement of the solenoid plunger when an external force acts on the lock case (20) of an electronic lock. An external force applied in a horizontal direction parallel to the direction of plunger motion may cause the solenoid plunger to displace allowing the lock to be opened without authorization. The addition of a properly sized anti-shock mechanism (60) limits displacement of the solenoid plunger due to an external force or impact and allows movement of the solenoid plunger when the solenoid plunger movement is due to an authorized access. When the lock is subjected to a force or impact, the anti-shock bellcrank (60) moves or rotates to a position that will limit the plunger's movement and prevent the mechanical components of the lock from being placed in positions that would permit the lock to be opened.
