Abstract
The present invention belongs to the locking technology for preventing lockset from being stolen and unlocked. A section of lost motion aiming at a lock core-a neutral position is designed before the action of the lock core is connected with a lock tongue or contacts the lock tongue and influences the action of the lock tongue. When the action of the lock core passes through the neutral position, a set of special-shaped marble holes are additionally arranged on a route which a layer of marbles of the lock core necessarily pass through on the inner wall of a lock core sheath when the lock core acts, and T-shaped suicide marbles are filled in (ambushed in) the special-shaped marble holes. The arrangement only permits that the lock core which is matched with a key smoothly passes through a suicide marble set; otherwise, the suicide marble set forcibly extrudes a layer of marbles to enter the marble holes of the lock core so as to fasten and pin in a suicide mode between the lock core and the lock core sheath before the action of the lock core influences the action of the lock tongue. The suicide marbles can only enter without withdrawing in design, and thus, the key is also unable to relieve the locking function. The lockset enables the life and the property of owners to be free from infringement through personal sacrifice (locking scrap), and the theft-proof performance of the lockset is exerted to the utmost limit. The present invention is the ground thread of the performance of the advanced theft-proof lockset, and can fundamentally restrain the technical unlocking.
