Abstract

The invention discloses a clutch structure with an idling lock core, and comprises a lock core inside a lock body. The lock core is composed of a front lock core and a rear lock core; a side lock bar slot on the front lock core comprises a side lock bar and a slider; the slider and the side lock bar are respectively arranged with a boss (matching with a groove) and a groove (matching with a boss); a slider resetting spring is positioned between the slider and the end wall of the side lock bar slot; a latch pin runner is arranged on the side lock bar slot on the rear lock core and corresponds with the front lock core; the latch pin runner inside is positioned with a latch pin; a latch pin resetting spring is arranged between the end wall, inside the latch pin runner and the latch pin; elasticity of the latch pin resetting spring is higher (smaller) than that of the slider resetting spring; at least one of the latch pin (slider) and the side lock bar slot wall (latch pin runner wall) adopts a slope to contact with the other one. The lock with the invented lock core clutch structure can effectively prevent damaging and unlocking the lock core with violent 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 lockpicking tool to forcibly twist the lock cylinder, the bolt fixing the lock head can be twisted off. 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 unlock. [...
