Abstract

The present invention discloses a clutch structure with a lock pith turning idly, and comprises a lock pith in the lock body. The present invention is characterized in that the lock pith is divided into a front lock pith and a back lock pith, a locking side column matching with a concave channel of the lock pitch marble is arranged in the channel of the locking side column of the front lock pith;a lock pin sliding channel is arranged at the back lock pith and the locking side column of the front lock pith respectively, an end wall is arranged at the lock pin sliding channel which is arrangedat the tail of the back lock pith, a lock pin is arranged in the lock pin sliding channel and a lock pin reset spring is arranged between the end walls of the lock pin sliding channel and the lock pin; a concave and convex combination is arranged between the locking side column and the lock pin; at least one of the lock pin or the locking side column channel adopts an inclination surface and contacts with the other. The present invention employs a lock with a lock pith of clutch structure, if a non-matching key is used to unlock, after the key is inserted into the front lock pith, the front lock pith is made to turn idly and the back lock pith fixed with a locking ruler cannot be turned, thus effectively preventing unlocking by violation tools.

Description

technical field [0001] The invention belongs to mechanical locks, and relates to a clutch structure and a lock head in which a pin lock core and a blade lock core can rotate idly. Background technique [0002] The pin lock and leaf lock locked by the existing side column structure, in the locked state, the lock cylinder can not rotate relative to the lock body. A prominent problem that the lock cylinder of this structure exists is: can not effectively prevent violent tool from prying and twisting the lock cylinder to unlock. If you use a strong enough unlocking tool to forcibly twist the lock cylinder, you can twist the bolts that fix the lock head on the door. Contents of the invention [0003] The purpose of the present invention is to address the above situation, to provide a clutch structure and lock head with a lock core that can be idling, and the lock core with the clutch structure can realize idling, and effectively prevent unlocking by twisting the lock core. ...
