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 and a sliding block are arranged in the channel of the locking side column of the front lock pith, matched convex and concave channelsare arranged on the sliding block and the locking side column and a reset spring for the sliding block is arranged between the sliding block and the end wall of the locking side column channel; 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 arranged at 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; elasticity of the pin shaft reset spring is larger than that of the sliding block reset spring; at least one of the lock pin or locking side column channel adopts an inclination surface and contacts withthe other. The present invention employs a lock with a lock pith of clutch structure, and effectively prevents unlocking by violation tools.

Description

technical field [0001] The invention belongs to mechanical locks, and relates to a clutch structure 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. 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 object of the present invention is to provide a clutch structure in which the lock cylinder can rotate idly in view of the above situation. The lock cylinder adopting the clutch structure can realize idle rotation, and effectively prevent violent tools from prying and twisting the lock cylinder to unlo...
