Both ends of the connecting shaft are respectively connected with the handle cover and the external handle through threads.

The door opener shell is connected with the lock body shell through bolts and superglue.

Principle of the present invention is as follows:

The signal to open the door is sent through the mobile phone APP, infrared remote control or wireless remote control, and the Bluetooth module, the infrared receiving head or the wireless receiving module of the easy-to-remove remote control door opening device for dormitory door locks receive the signal to open the door signal, the single-chip microcomputer performs signal processing, and the motor drive module drives the geared motor to rotate clockwise 90°, and the torque of the geared motor drives the handle to make the handle of the lock body rotate accordingly, thereby To achieve the purpose of opening the door. After a period of delay, the geared motor turns counterclockwise by 90° and returns to the initial state.

The invention allows the user to remotely open the door when it is inconvenient to get up and open the door, and can use a power bank for power supply, which is small and convenient, and is especially suitable for dormitory door locks such as colleges and universities. Easy disassembly and assembly, high safety and low cost.

Based on the above reasons, the present invention can be widely promoted in the fields of building doors and the like.
