A double-sided locking tongue structure

Abstract

The invention discloses a double-sided deadbolt structure, which relates to the technical field of lock cylinder and deadbolt structure; in order to solve the problem of inconvenient operation of double deadbolt locks; it specifically includes a dilution box; the inner wall of one side of the lock box is connected with a drive Motor; the inner walls on both sides of the lock box are respectively fixed with touchable display screens by screws; the inner wall on one side of the lock box is fixed with electric telescopic rods; the outer wall of one side of the electric telescopic rods is fixed with push plates by screws; One side of the outer wall is fixedly connected with a driving telescopic column by screws. In the present invention, by setting an electric telescopic rod and a touchable display screen, the electric telescopic rod can be operated after password or fingerprint verification through the touchable display screen, so that the electric telescopic rod shrinks, and the telescopic rod is driven to shrink in the direction of the electric telescopic rod and the driving spring The locked door is opened under the elastic force, and there is no need to look for the key, which saves a lot of time and improves the flexibility of the device.

Description

technical field [0001] The invention relates to the technical field of lock cylinder lock tongue structures, in particular to a double-sided lock tongue structure. Background technique [0002] The double deadbolt is a kind of lock that uses a key to open the door outside and inside the door. Its confidentiality is higher than that of a single lock. After a thief enters the door, it cannot be opened without a key. In addition, most of them also have a defense function, as long as there is no key. The lock tongue is retracted, and the lock cannot be removed with ordinary tools, such as screwdrivers, pliers, and hammers. At present, in the prior art, the double lock tongue also has disadvantages: in emergency situations (such as escape in case of fire, it is more difficult to escape) There is no single lock for convenience, and it is easy to make mistakes while busy, resulting in delayed timing. Therefore, there is an urgent need for a convenient double-sided lock tongue struc...

Problems solved by technology

[0002] The double bolt is a kind of lock that can be opened with a key both outside and inside the door. Its security is higher than that of a single lock. After a thief enters without a key, he cannot open it. In addition, most of them also have defensive functions. As long as there is no key to handle The dead bolt is indented, and the lockset cannot be unloaded with general tools such as screwdrivers, pliers, and a hammer. At present, in the prior art, the double dead bolt also has a shortcoming: in an emergency (escape is just more difficult as a fire alarm) It is not as convenient as a single lock head, and it is easy to make mistakes in a busy schedule and cause delays in timing. Therefore, a convenient double-sided lock tongue structure is urgently needed

The double lock bolt structure in the above patent is difficult to operate in case of emergency (e.g., it is more difficult to escape in case of fire), which wastes precious escape time and reduces the practicability of the device
