A non-porous magnetic lock

Abstract

The invention discloses a holeless magnetic lock which comprises a lock body, a lock tongue and a lock cylinder, wherein a cylindrical cavity capable of accommodating the lock cylinder is formed in the lock body; a strong magnet is arranged inside the lock cylinder; a blind hole matched with the lock tongue is formed in the outer side surface of the lock body; a through hole communicating with thecavity is formed in the bottom surface of the blind hole; the lock tongue can slide in the blind hole; a transmission rod is fixedly connected with the end, close to the bottom surface of the blind hole, of the lock tongue; two positioning pins I are fixedly connected with one end of the transmission rod, arranged in a spacing manner, and parallel to the horizontal rotating surface of the lock cylinder; a positioning pin II is fixedly connected with the edge of the upper surface of the lock cylinder; the other end of the positioning pin penetrates through the space between the two positioningpins I; and when the lock cylinder rotates, the lock tongue is driven to extend out of or retract into the blind hole. By utilization of the basic principle that strong magnetic force is produced bya high-strength magnet, the holeless magnetic lock replaces a conventional lock tongue structure; meanwhile, the holes design is adopted, so that a thief has no way to pick the holeless magnetic lock,and the holeless magnetic lock can be effectively prevented from being stolen; and furthermore, the holeless magnetic lock is not easy to be blocked by dust or corroded, and can effectively adapt todiversified outdoor environments.

Description

technical field [0001] The invention relates to a lock, in particular to a non-hole magnetic lock. Background technique [0002] With the strengthening of the national economy, the investment in municipal facilities in my country has continued to increase, and the overall quality of the municipal environment has been improved, but the phenomenon of theft of municipal facilities has never been eliminated. In the case of theft of municipal facilities, manhole covers, street lamps, cables, and light boxes are the main objects of theft. The theft of street lamps, cables, and light box facilities has seriously affected the normal operation of street lamps, and the environment of extinguishing lights makes it easier to carry out illegal and criminal acts such as robbery, snatching, and theft; Direct economic losses pose a great threat to people's lives and property safety. Although the relevant government departments have taken a number of measures to strengthen the security pro...

AI Technical Summary

Problems solved by technology

However, this type of lock has poor anti-theft standards. It is easy to open the lock cylinder by external force or use simple tools and be stolen by criminals.

Since most of the municipal facilities are in the outdoor environment, rainwater can easily seep into the keyhole, which will cause the lock to rust for a long time, making it difficult to open for maintenance
