Dual safety lock

Abstract

The invention discloses a double safety lock head, which comprises a lock cylinder placed in the lock body, the lock cylinder is connected with a crank, an elastic lever is arranged on the crank, and a motor and a speed reducer are arranged on the bottom plate connected with the lock body. device, the input end of the deceleration device is connected to the motor, the output end of the deceleration device is connected to the crank blocking device, and a reset mechanism and a switch are arranged on the bottom plate. To prevent illegal opening, better safety performance, simple control, strong versatility, low power consumption, and convenient operation.

Description

technical field [0001] The invention belongs to the field of locks, in particular to a safety lock head for preventing illegal opening. Background technique [0002] The mechanical lock head is the basic part of all kinds of locks. It is usually composed of lock body, lock cylinder, pin and blade and other components. , the lock cannot be opened legally, as long as the matching key is inserted, it can be opened legally. In order to solve the problem that sometimes the legal key is difficult to recover after lending, such as home decoration, someone invented an AB lock that is used in sequence and time-sharing, that is, one lock has two kinds of keys, B is the decoration key, and A is the owner's key. , insert the A key and turn it, the B key will be permanently invalid, so the A key cannot be used during the use of the B key.

Problems solved by technology

[0002] The mechanical lock head is the basic part of all kinds of locks. It is usually composed of lock body, lock cylinder, pin and blade and other components. , the lock cannot be opened legally, as long as the matching key is inserted, it can be opened legally

In order to solve the problem that sometimes the legal key is difficult to recover after lending, such as home decoration, someone invented an AB lock that is used in sequence and time-sharing, that is, one lock has two kinds of keys, B is the decoration key, and A is the owner's key. , Insert the key A and turn it, the key B will be permanently invalid, so the key A cannot be used in the stage of using the key B

Generally speaking, because the structure of the traditional mechanical lock head is relatively simple and widely used, it is easy to be opened by people with the help of ordinary tools.

With the development of electronic technology, various electronic combination locks have appeared. The security of this kind of lock has been improved, but it is also easy to be decoded by high-tech means. Therefore, its use is not very safe. , and the daily power consumption is large,

In view of the shortcomings of the above two kinds of locks, some people currently adopt the method of setting two sets of locks at the same time, that is, a set of mechanical locks and a set of electronic combination locks, so as to further improve the safety of locks, but this not only increases the cost of locks , there are many inconveniences in using
