Asynchronous mechanical ball-free antitheft multi-protection lock

Abstract

The invention discloses an asynchronous mechanical ball-free antitheft multi-protection lock. The asynchronous mechanical ball-free antitheft multi-protection lock is characterized in that a rear lock core and a front lock core are completely disconnected; a sliding hole, a dedicated key hole and an invisible hole are formed in the front lock core, a connecting body is arranged in the invisible hole, and the connecting body is disconnected from the rear lock core; a locking hole and a connecting hole are formed in the rear lock core, and a connecting tongue which is arranged at the rear end of the rear lock core is connected with a linkage mechanism after penetrating through a through hole and is then connected with a lock tongue; a locking head is arranged in front of a locking spring which is arranged in a locking bearing hole, the locking head and an ejecting rod are arranged in the locking hole, and a sliding rod which is arranged in front of the ejecting rod is arranged in an extrusion groove and the sliding hole; the expansion end of an expansion piece stretches into the extrusion groove for locking the front lock core, and an oblique locking device and a rotary locking device are used for locking the front lock core. The asynchronous mechanical ball-free antitheft multi-protection lock disclosed by the invention has the advantages that mechanical interlocking, invisibility and connecting invisibility of the front lock core and the rear lock core are integrated into a whole, thus an interlocking device cannot be opened by a thief, and the rear lock core cannot be rotated by the thief; only the front lock core can be rotated even though an interlocking part and a self locking part are damaged by an uncivilized means, the rear lock core cannot be rotated, and a complete antitheft function is achieved.

Description

technical field [0001] The invention relates to an asynchronous mechanical non-bullet anti-theft multiple 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 object, the asynchronous mechanical non-bullet anti-theft multi-lock of the present invention does not have a l...

Problems solved by technology

[0002] There are many kinds of anti-theft locks in use now, but basically the key is used to open the marble and then rotate to drive the deadbolt to open the anti-theft lock. There is no interlock, The combination of asynchronous locking and self-locking anti-theft lock makes it easy for thieves or unlock kings to open the anti-theft lock

There are basically no anti-theft locks that can't be opened by thieves and locksmiths.
