Lock cylinder

Abstract

The invention relates to a lock cylinder. The lock cylinder is characterized in that an electronic core shell and an antenna are arranged in the lock cylinder, a mechanical lock container, a movable pin, a movable pin reset spring and a movable pin limiting structure are arranged behind a lock hole, wherein the movable pin is sleeved with the movable pin reset spring. A small shifting wheel and a large shifting wheel which axially penetrate into a meshed concave-convex structure are arranged behind the movable pin at an interval, an electronic movable pin cam integrally provided with an electronic movable pin is arranged behind the small shifting wheel, a projecting shaft of the movable pin is inserted into the a center hole of the electronic movable pin, the projecting shaft of the movable pin is provided with a small shifting wheel spring, a motor cam connected with a motor abuts against the electronic movable pin cam and the electronic movable pin, the motor can rotate in the axial direction, and a space allowing the electronic movable pin cam and the electronic movable pin to move backwards is formed after the motor cam rotates. The lock cylinder can achieve unlocking authentication with two modes of mechanical authentication and electronic authentication, unlocking legality is effectively improved, the safety of the lock cylinder is improved, no electric shock risk exists during operation, and the reliability of the lock cylinder is ensured.

Description

technical field [0001] The invention relates to a lock cylinder, in particular to a multi-mode lock cylinder controlled by mechanical coding and electronic coding. Background technique [0002] Electronic lock is a lock form commonly used in some specific fields at present. It controls unlocking or locking by judging the authority of the key inserted into the lock cylinder through the power supply and circuit in the lock body or key body. The lock hole of the traditional electronic lock is generally a marble unlocking structure, which is easy to be cracked by violence. For example, insert a foreign object or use an electric drill to drill out the lock cylinder. Obviously, there are obvious security risks in this structure. Therefore, as long as a mechanical key is used, no matter what kind of lock cylinder it is, it can be cracked through techniques and tools. Although currently on the market there are smart lock cylinders controlled by miniature electromagnets, such lock...

AI Technical Summary

Problems solved by technology

Although there are smart lock cylinders controlled by miniature electromagnets on the market, such lock cylinders are relatively weak against vibration and strong magnetism, resulting in relatively weak anti-technical opening capabilities.

At the same time, most of the smart locks now have an integrated structure. If you want to upgrade the traditional mechanical lock to a smart lock, you can only replace the entire lock body, and the appearance of the replaced lock body is not necessarily the same as the decoration style of buildings and doors. As coordinated as the original lock, which affects the aesthetics
