Embodiment Construction

[0017] Such as Figure 1 to Figure 7As shown, the active rotating core guard plate [1], the driven rotating core guard plate [4], and the rotating core protection round tube [5] are fixedly combined to form a fully enclosed structure of the rotating core protective shell, and the rotating core protective shell is formed A cylinder-shaped cavity is provided to accommodate the active rotating core [2] and the driven rotating core [3]; the lower marble hole [6] processed on the driven rotating core [3] and the driven rotating core guard plate [4] The upper marble hole [7] of the upper processing is equipped with a lower marble [8], an upper marble [9], and a pin spring [10] to form a key inspection mechanism; in the key transmission gap of the active rotating core [2] [ 11] is inserted with a key [12], and the key [12] has a pit that accepts the inspection of the lower pin [8]; [13] inserted into the key delivery notch [11] or pulled out from the key delivery notch [11]; relying...

Abstract

The invention relates to a key-check lock cylinder, which can be used for checking a key in a state of isolating with the outside during the unlocking. In order to ensure no friction between the key and a marble when a key transferring member is used for transferring the key, the diameter of a marble hole processed on a driven member, facing to the end face of the key transferring member, is less than that of the marble hole, backing to the other end face of the key transferring member, correspondingly, the diameter of the marble arranged in the marblehole, facing to one end of the key transferring member, is less than that of the marble, backing to the other end of the key transferring member, and the small diameter end of the marble can not be in contact with the key transferring member when the marble is moved to the limit position towards the direction of the key transferring member from the marble hole of the driven member, therefore, when the key is transferred to a key checking region, the key is not in contact with the marble, i.e. no friction resistance exists. The invention can be a lock directly locking a rotating shaft and can be also cylinders of other anti-theft locks.

Description

Technical field [0001] The invention relates to a structure in which an active rotating core and a driven rotating core are stacked together in a protective cover of the rotating core in a lock cylinder. 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 key inspection area, the lower marbles are in contact with the active rotating core and the key, so the lower marbles cause frictional resistance. Contents of the invention [0003] The invention provides a lock core, when the active rotating core transmits the key to the lower pin of the key inspection mechanism, the lower pin does not contact with the active rotating core and the...
