AI Technical Summary
Existing locks have insufficient anti-theft performance in terms of preventing technical unlocking, and are difficult and costly to manufacture.
A mechanical lock is designed, comprising a lock head body, a lock cylinder, and a key. An interception mechanism is configured on the lock cylinder. The key has a perforated structure. The interception mechanism can extend into the perforated structure of the key to block non-matching keys or foreign objects from entering the keyhole. The lock is unlocked by password through the linkage of a trigger mechanism and the interception mechanism.
It improves the anti-theft performance of locks, while reducing the difficulty and cost of manufacturing parts, enhancing the security of keys, and preventing non-matching keys or foreign objects from entering the keyhole.
