An anti-displacement device inside a rotating ring of an idle lock cylinder

Abstract

The invention discloses an anti-displacement device inside a rotating ring of an idle lock cylinder, and relates to the field of lock cylinder devices. The invention solves the problems that the interlocking teeth on the rotating ring in the current lock core are easily dislocated by external force and are not rainproof and dustproof. The anti-displacement device inside the rotating ring of the idling lock cylinder is provided with a guide cylinder and a telescopic spring. A cylinder groove is arranged inside the lock core sleeve, and a tooth groove and a spring hole are arranged on the outside of the guide cylinder. Position ring; the limit rod is fixed vertically on the anti-extraction teeth on the spacer ring at the notch end of the cylinder. The invention is easy to process, convenient to use and safe and reliable.

Description

technical field [0001] The invention relates to the field of a lock cylinder device, in particular to an anti-displacement device inside a rotating ring of an idle lock cylinder. Background technique [0002] The existing lock cylinder mainly adopts pins of different heights to cooperate with each other. When the key is inserted into the lock core, the lock will be opened according to the teeth corresponding to the pins of different heights on the key. Therefore, the existing technology is to use this structure to unlock the lock. It is easy to quickly open the lock with a tool test. At the same time, the production of pin locks also has some problems of duplication of keys and locks, that is, keys in the hands of different people can open the same lock, which also reflects the disadvantage of the high repetition rate of current pin lock cylinders. [0003] In order to improve the anti-technical unlocking function of locks and reduce the disadvantages of key or lock cylinde...

AI Technical Summary

Problems solved by technology

[0004] However, in the lock cylinder structure of anti-idling technology unlocking, the linkage teeth on the rotating ring need to be arranged in a straight line before unlocking. The teeth can displace the interlocking teeth on the rotating ring so that the interlocking teeth in the lock cylinder are not in a straight line, so that the key corresponding to the interlocking teeth on the rotating ring cannot be inserted into the lock cylinder, resulting in the lock being unable to open, so the current idling The lock cylinder that prevents technology unlocking has the disadvantage that the linkage teeth on the rotating ring are easily misplaced

[0005] Because the existing idling anti-technology unlocking lock cylinder is provided with a keyhole for key insertion, rainwater or other foreign matter can easily enter the lock cylinder, causing the lock cylinder to rust and affect normal use.
