Novel double-layer lock cylinder anti-theft device

Abstract

The invention discloses a novel double-layer lock cylinder anti-theft device. The novel double-layer lock cylinder anti-theft device has a lot of differences from the conventional anti-theft devices, and is much improved. Most of the conventional anti-theft devices are simple in structure due to the adoption of single lock cylinders, are easily broken by other unlocking tools, and are relatively low in practicability and security. Thus, in an ordinary anti-theft device, the condition of a single lock cylinder is changed, an inner lock cylinder and an outer lock cylinder are mounted, a powerful anti-theft effect is generated through the close integration and linkage of the inner lock cylinder and the outer lock cylinder, the inner lock cylinder is combined with the outer lock cylinder, and the security of the anti-theft device becomes higher under the condition without changing simple operation. The novel double-layer lock cylinder anti-theft device is simple to manufacture and high in practicability and security, facilitates the life of people, and solves a lot of problems of people.

Description

technical field [0001] The invention relates to a daily necessities device, in particular to a novel double-layer lock cylinder anti-theft device. Background technique [0002] The anti-theft devices commonly used in our families now mostly adopt a single lock cylinder, which has a simple structure and is easy to be destroyed by other unlocking tools, so the practicability and safety are relatively low. According to the above contradictions, this novel double-layer lock cylinder anti-theft device has been invented, which solves the problems of poor practicality and safety of general anti-theft devices. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a novel double-layer lock cylinder anti-theft device. [0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows: the device includes a lock body, an inner lock cylinder and an outer lock cylinder. I...
