Problems solved by technology

Then, even if the mating key is inserted and turned again, only the rotor turns and the plunger does not move, thus causing a problem that the normal unlocking operation cannot be performed because the link is not connected with the rotor
[0006] Also, the plunger locks described above involve a problem in that assembling multiple components requires complex operations and requires specific or specialized jigs

Abstract

A cylinder lock capable of normal unlocking operation by an authorized key to a locking mechanism which has been illegally operated by an unauthorized key or the like, the cylinder lock comprising an engaging portion that engages a rotor in the rotational direction only when the cylinder moves toward the unlocking member is disposed to a cylinder to engage the rotor and the cylinder thereby rotating the rotor upon subsequent insertion of an authorized key to connect the rotor and the connection member thereby enabling normal unlocking operation.

Description

technical field [0001] The present invention relates to a plunger lock for locking and unlocking a door locking device used, for example, on a vehicle, and more particularly, to a plunger lock capable of preventing illegal unlocking of the locking device. Background technique [0002] Plunger locks generally include a housing having a bayonet and being fixed to a base (such as a vehicle body), a rotor having a retractable tumbler rotatably disposed within the housing, and a small diameter portion connected to the rotor and An unlocking element operatively associated with a locking device. In the above structure, when the matching key is inserted and the rotor is turned, the tumbler can be retracted from the outer peripheral surface of the rotor, and then the rotor can be turned within the housing. Thus, the unlocking element can also rotate with the rotor, making it possible to lock and unlock the locking device via a transmission element, such as a lever. [0003] Convers...
