Coded lock cylinder system with variable tooth profile

Abstract

The invention discloses a coded lock cylinder system with a variable tooth profile, and belongs to the technical field of locks. A user-defined code area is arranged on a key, and a code setting area capable of adjusting billiard length is arranged on the corresponding lock cylinder, so that a user can set or change the key code combination, and modify the corresponding billiard length in the lock cylinder so as to be correspond to the key newly set by the user, and thus the user can set the key and the lock cylinder codes according to own requirement and does not need to replace the lock cylinder after the key is lost, the labor and material costs are reduced, and the property and personal safety risks are also reduced. In addition, the coded lock cylinder system with the variable tooth profile adopts the manner of combination of a transmission ring and an operating button, when the key is inserted into a key hole, no action is permitted, and only the operating button at the bottom of the lock cylinder is used for operating the lock cylinder shift fork to control a master lock body on a security door or other devices to act, so that various ways of traditional cracking cannot be achieved by impacting and shaking the buttons or the key, and thus the safety of the lock cylinder is ensured.

Description

technical field [0001] The invention relates to a lock, in particular to a variable tooth-shaped coded lock cylinder system, which belongs to the technical field of locks. Background technique [0002] At present, in the world, all mechanical lock cylinders and keys do not allow users to change or set key codes, and these key codes are all set at the factory. Once the user loses the key, even if it is lost in a different place, a lot of manpower and material resources must be spent to replace the lock cylinder, otherwise no matter from the reality or the user's psychology, the property and personal safety in the future cannot be guaranteed. Although with the advancement of science and technology, new types of encrypted locks such as fingerprints, numbers, and combination disks continue to appear, these locks cannot solve two fundamental problems. One is the high cost. Such high-tech locks cost hundreds or even thousands of dollars. , does not include the installation cost; ...

AI Technical Summary

Problems solved by technology

[0003] Although purely mechanical combination locks have already existed, such as safe locks, etc., usually no more than 6-digit combination, and the combination disk will be exposed, users are more worried about the thief who tries for a long time or pays attention to get the password when he unlocks the lock, so Carrying the key (password) with you is still the most recognized security method for every user

In addition, operating the password dial is still a major barrier to use for special users such as the elderly, children, and the blind

[0004] In addition, the current existing mechanical lock cores all work in the way that the key is combined with the rotation of the lower billiard chamber.

This method also has two disadvantages. One is that the key code cannot be set by the user. The combination of all key teeth is set by the manufacturer before leaving the factory, and the user cannot change it by himself.

Once the key is lost or the new house is decorated, the user must replace all the keys and lock cylinders, which takes a lot of time and labor costs

At the same time, the waste lock cylinder also causes a certain waste and pollution of metal and other materials.

The second is that the cracking method designed for this working method is very mature; in addition to the master key and violent methods in the past, the most popular tin foil unlocking poses a considerable threat to these locks
