Inner staggering preventing device for rotating ring of idling key cylinder

Abstract

The invention discloses an inner staggering preventing device for a rotating ring of an idling key cylinder, and relates to the field of key cylinder devices. The inner staggering preventing device for the rotating ring of the idling key cylinder solves the problems such as that linkage teeth on a rotating ring in a current key cylinder are easily staggered by outside force and cannot resist rainand dust. The device is provided with a guide barrel and a telescoping spring, wherein a barrel groove is formed in a key cylinder sleeve; a tooth groove and a spring hole are formed in the outer sideof the guide barrel; a limiting ring is arranged at the end, positioned into the spring hole in the guide barrel, of the tooth groove; and limiting bars are vertically fixedly arranged on anti-draw teeth on an isolating ring at a port end of the barrel groove. With the adoption of the device, the processing is easy; and the device is convenient to use, 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.
