Mechanical asynchronous interlocking additional marble-free burglar-proof lock

Abstract

The invention discloses a mechanical asynchronous interlocking additional marble-free burglar-proof lock. A rear lock cylinder is completely separated from a front lock cylinder. A connecting body is installed in an invisible hole and separated from the rear lock cylinder. A locking hole and a connecting hole are formed in the rear lock cylinder, and after penetrating through a via hole, a connecting tongue at the rear end of the rear lock cylinder is connected with a linkage mechanism and then connected with a lock tongue. A locking head is arranged in front of a locking spring in a locking bearing hole and locks the rear lock cylinder, a sliding bar is installed in a sliding hole, and a sliding block is installed in a sliding groove and a turning groove. The fixed end of an expanding piece is fixed in an expanding groove, the expanding end of the expanding piece stretches into a locking groove to lock the front lock cylinder, and a rotating block locks the front lock cylinder in an inclined groove and an inclined locking groove. The burglar-proof lock integrates mechanical interlocking, invisibility and invisible connection of the front lock cylinder and rear lock cylinder, and therefore a burglar can not open an interlocking device or rotate the rear lock cylinder; the burglar can only rotate the front lock cylinder even though damaging an interlocking part and a self-locking part in a violent manner, the rear lock cylinder can not be rotated, and therefore a complete burglar-proof effect is achieved.

Description

technical field [0001] The invention relates to a mechanical asynchronous interlocking additional bulletless anti-theft lock in the field of anti-theft locks. Background technique [0002] There are many kinds of anti-theft locks in use now, but basically all of them use the key to open the marble and then rotate to drive the deadbolt to open the anti-theft lock. It was the unlock king who easily opened the anti-theft lock. There are basically no anti-theft locks that thieves and unlocking kings cannot open. Contents of the invention [0003] The purpose of the present invention is to provide a kind of anti-theft lock that can't be opened by thieves and unlocking kings, which integrates asynchronous interlocking, self-locking and mechanical interlocking, high security, the manufacture of anti-theft locks without marbles and its method. [0004] In order to achieve the above-mentioned purpose, the mechanical asynchronous interlocking additional bulletless anti-theft lock...
