Electronic lock hole protective device with electromagnetic clutch

Abstract

The invention discloses an electronic lock hole protective device with an electromagnetic clutch, which relates to the field of electronic locks. The protective device comprises an electronic lock body, an electronic key and the electromagnetic clutch, wherein the electromagnetic clutch is arranged on a lock cylinder of the electronic lock body and comprises an electromagnet, a bracket and a lock hole sliding plate; the bracket is arranged outside the lock cylinder and on the inner side of an electronic lock body protective plate; the lock cylinder passes through the bracket and the electronic lock body protective plate; the protective plate is provided with a lock hole through which a key is inserted into the lock cylinder; the electromagnet is arranged on the bracket; and the lock hole sliding plate is arranged between the lock cylinder and the lock hole. The protective device has the advantages that: the lock hole sliding plate is a push slide type mechanism and is matched with an electronic lock protective plate, so that a lock hole cover plate is integrated with the protective plate; simultaneously, the electromagnetic clutch is not limited to be controlled by the electromagnetic clutch. The lock hole protective device also relates to protection of the lock hole by motor engagement or by driving a lock hole switch through a motor.

Description

technical field [0001] The invention relates to the field of electronic locks, in particular to an electronic keyhole protection device with an electromagnetic clutch. Background technique [0002] The keyhole is the key hole for mechanical unlocking. The traditional keyhole is exposed outside. It has the following disadvantages: 1. It is not dust-proof, and it is easy to cause failure after dust enters the lock cylinder; 2. It is easy to be artificially blocked by foreign objects, resulting in failure Unlocking; 3. It is easy to be opened by technology, and the security is not high, especially for electronic locks. The key amount of the lock is definitely less than that of the mechanical lock cylinder. The security of the lock depends entirely on the mechanical lock cylinder. Any high-end electronic unlocking method is just a decoration. [0003] In order to solve this problem, people have invented a lot of devices for protecting the keyhole, which mainly contain the follo...

AI Technical Summary

Problems solved by technology

The above method can solve the problems of dustproof, anti-blocking and anti-technical opening, but the use of mechanical auxiliary devices is both troublesome and not safe. incomparable

[0004] Obviously, neither of the above two types can solve the problem of low security of locks, and it is more troublesome to unlock, which does not meet the requirements of simple operation and high security required by electronic locks, and is not suitable for large-scale applications.

[0005] The keyhole protection that is still popular in the market is mainly to use a cover plate with an opening to buckle tightly in the keyhole, and use a hook or special tool to open the cover plate; or use a key with a magnet to absorb the magnetic cover on the keyhole board, or push the skateboard on the keyhole by hand. Although these methods have made some progress, their safety performance is relatively low.
