Abstract

The invention relates to a pin tumbler lock core, in particular to the pin tumbler lock core which can prevent a universal key from stirring a pin tumbler for unlocking. In order to prevent the universal key from stirring the pin tumbler, the pin tumbler of the pin tumbler lock core is isolated from outside, that is the pin tumbler of the pin tumbler lock core is sheltered by a rotating part protective housing which is formed by fixedly combining a key-conveying rotating part baffle plate, a driven rotating part baffle plate and a rotating part protective circular pipe for surrounding a key-conveying rotating part and a driven rotating part, as well as a the key-conveying rotating part and the driven rotating part so as to be isolated from the outside, the concealed key is conveyed to the space below the pin tumbler which is isolated from the outside by relying on the key-conveying rotating part for inspection and unlocking, and the problem of avoiding stirring the pin tumbler for unlocking is thoroughly solved.

Description

Technical field [0001] The invention relates to a tumbler lock cylinder capable of preventing thieves from using a universal key to turn the tumbler to unlock the lock. Background technique [0002] In order to prevent thieves from using a master key to turn the pin to unlock the pin to the rotating part of the lock cylinder, people have invented various anti-dial pin pin lock cores, and their common disadvantage is: through the keyhole of the pin pin lock core , the master key can still touch the marbles, which leaves an opportunity for the thief to move the marbles to open the lock. Contents of the invention [0003] In order to overcome the above-mentioned deficiency that the master key can touch the pins through the key hole of the pin lock cylinder, the present invention provides a pin lock core, the pins of which are always isolated from the outside world, so the master key cannot touch the pins at all. [0004] The technical solution adopted by the present inventio...
