An isolated anti-theft lock structure

Abstract

The invention relates to an isolated anti-theft lock structure and belongs to the technical field of hardware locks. A casing is a hollow cuboid or a cylinder used for containing and assembling all parts. A user can detach a rear end cover and replace a slider by himself or herself to conduct encryption. A movable slide for a lock cylinder, a scissors body or a check valve is arranged on the inner surface. The slider is an I-shaped or U-shaped cuboid strip installed in the lock cylinder, and a slider slot for the check valve to fall in or pass is formed in the slider. When a location ball or double inclines of a key hole through location device enter the location hole or double slots, a key can be inserted to push the slider to move. The isolated anti-theft lock structure has the three-direction output type, the rotating type, the addition type, the key-free type, the movable type and the cluster typical type. Unlocking can be conducted only after the key is pulled out, the qualitative leap of the anti-theft technology from increasing the stealing unlocking difficulty to completely eradicating stealing unlocking is achieved. Meanwhile, the original lock is not required to be disassembled, a layer of anti-theft protection is added on the isolation lock, and users with the anti-theft lock can use the structure conveniently.

Description

technical field [0001] The invention relates to an isolated anti-theft lock structure, which belongs to the technical field of hardware locks. Background technique [0002] Anti-theft locks are inseparable from everyone and are an important device that is used almost every day. Based on reasons such as practicality, cheapness, convenience, and durability, mechanical anti-theft locks occupy an absolute market all the time. Although it has been improved from generation to generation, one technology after another, its security is still very fragile. The most common tumbler lock is taken as an example below to illustrate the major problems in the prior art, and analyze the reasons why the problem has not been completely cured. [0003] The pin lock is to use the length or uneven shape of the key to squeeze the pins in the lock cylinder to make them all reach the appropriate position, and unlock the lock without preventing the rotation of the lock cylinder. After the key is pu...

Problems solved by technology

After a certain period of use, there will be a loose frame between the parts, and even leave traces of key use for thieves, and the anti-theft ability will deteriorate.

In addition, it will shorten the service life and cause problems such as poor flexibility.

It is normal to change the lock cylinder every two or three years for a lock that is normally used. In life, we often see new locks filled with lubricating oil or lead (pen core) powder within one year, and it may happen that your own key cannot open the lock at any time. situation, which increases the cost of use and brings a lot of trouble to the user, which is also an unavoidable defect of the existing lock technology

[0005] The above-mentioned disadvantages are problems that cannot be solved under the principle of existing lock making technology. In the face of the advanced theft technology and modern unlocking tools that are difficult to guard against, and then use the existing anti-theft design ideas, it is not too big to blindly innovate or upgrade the contact lock structure. Significantly, we must completely change the existing lock making principle, eliminate the necessary condition of "contact" being stolen, and invent a series of new anti-theft locks, in order to effectively solve the problems existing in the background technology
