Problems solved by technology

Its design has the following main shortcomings: in the process of transferring the key to the pin under the key inspection mechanism, the lower pin is in contact with the rotating part of the key transmission and the key, so the lower pins have caused frictional resistance to the rotating part of the key transmission and the key

Embodiment Construction

[0027] like Figure 1 to Figure 19As shown, the cylindrical transmission key rotating member shield [1], the cylindrical driven rotating member shield [2] and the circular tube-shaped rotating member protection tube [3] are fixedly combined to form a transmission key rotating member [4] and the rotating part protection case of the driven rotating part [5] of cylindrical shape, the shape of the inner chamber of the rotating part protecting case is cylindrical; the transfer key rotating part [4] and the driven rotating part [5] are accommodated In the cylindrical inner cavity of the rotating part protective shell; the projection of the transmission key rotating part [4] on the axis line direction of the tumbler lock cylinder or anti-theft locking device is approximately U-shaped, and the transmission key rotating part [4] is processed with The transmission key groove [6], the transmission key groove [6] is from the end face of the transmission key rotation part [4], which is in ...

Abstract

The invention relates to a pin lock core or an anti-theft locking device which can prevent the pin pin from being unlocked by a universal key. In order to prevent the tumbler from being pulled, the transmission key mechanism transmits the key to the state of being isolated from the outside of the tumbler lock cylinder or anti-theft locking device for key inspection; in order to prevent the pintle from producing frictional resistance on the key, the transmission key rotating part rotates and transmits the key to the key inspection When the lower pin of the mechanism is at the position, the lower pin is not in contact with the rotating part of the transmission key and the key, so there is no frictional resistance caused by the lower pin, which completely solves the problem of unlocking the lock with the anti-pick pin and the frictional resistance of the pin against the key .

Description

Technical field [0001] The invention relates to a pin lock cylinder or an anti-theft lock device for checking the key when a key transmission mechanism transmits the key to the pin lock core or the anti-theft lock device in a state of being isolated from the outside. Background technique [0002] At present, the known phase-stacked structure isolating the key-checking tumbler lock cylinder has application number to be 200610024350.7 anti-dialing tumbler lock cylinder with phase-to-stack structure and the anti-theft lockset that application number is 200610030741.x. Its design has the following major deficiencies: in the process of transmitting the key to the lower pin of the key inspection mechanism, the lower pin is in contact with the rotating part of the key transmission and the key, so the lower pins have caused frictional resistance to the rotating part of the key transmission and the key. Contents of the invention [0003] The invention provides a tumbler lock cylind...
