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 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; 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 a mechanical lock, and relates to a clutch structure capable of idling a pin lock core and a blade lock core and a lock head thereof. Background technique [0002] In the existing pin lock and blade lock with the side column structure locked, the lock core of the lock cylinder cannot be rotated relative to the lock body in the locked state. A prominent problem of the lock cylinder of this structure is that it cannot effectively prevent the violent tool from picking the lock cylinder to unlock. If you use a strong enough unlocking tool to twist the lock cylinder forcibly, you can twist off the bolts that fix the lock head on the door. Summary of the invention [0003] The purpose of the present invention is to provide a clutch structure with idling lock cylinder and its lock head in view of the above situation. The lock cylinder adopting the clutch structure can achieve idling rotation and effectively prevent the lock cylinder from ...
