Door locking device capable of improving security performance

Abstract

The invention belongs to the field of security protection devices and particularly relates to a door locking device capable of improving the security performance. In order to solve the problems that more and more varied door locking devices for existing security protection devices are too simple and poor in security protection performance compared with original door lock structures, the door locking device capable of improving the security performance is provided. The door locking device capable of improving the security performance comprises a door body. One side of the door body makes contact with a door frame. The front side of the door body is fixedly connected with a fingerprint panel. The door body is provided with a rectangular cavity. The inner wall of one side of the rectangular cavity is fixedly connected with a controller and a driving motor. A driving shaft is welded to an output shaft of the driving motor. The inner walls of the two sides of the rectangular cavity are eachprovided with two driven holes. A driven shaft is rotatably mounted in every two driven holes located on the same horizontal axis. The outer sides of the driving shaft and the driven shafts are all fixedly sleeved with belt pulleys. The door locking device capable of improving the security performance can effectively improve the door locking strength and effectively improve the security of a locked door and is easy and convenient to operate.
