Generally, door locks are installed in doors of places such as houses, apartments, or offices to prevent unauthorized outsiders from entering the building.

Most of these door lock devices are electronic or digital door locks that control the accessor for the purpose of security and security by automatically locking / unlocking the door by an electrical signal.

However, the conventional digital door lock is configured so that the door is automatically locked when a predetermined time elapses after opening the door, but there is no need to perform a separate locking operation, but it is automatically locked by the elapsed time regardless of the closing of the door. When the door is open, the lock may protrude even if the door is open.In this case, there is a hassle to turn the inner control lever to return to the previous state and then close the door again. If you fail to do so, you can go out in a state where the door is not locked correctly.

In order to solve the above problems, it is equipped with a magnetic sensor to detect whether the door is opened or closed and a limit switch to detect whether the dead bolt is locked so that the dead bolt is locked when the door is closed correctly to maximize security and security. In addition, the structure is simple and the manufacturing cost can be saved by reducing the parts. A deadbolt type electromagnet door lock (patent registration number No. 0475638) has been proposed for the purpose of improving the reliability of the product, such as easy installation and shortening the working time, which will be briefly described as follows.

In the case of the above-mentioned deadbolt electromagnet door lock, the solenoid receiving groove and the insertion piece of the solenoid are largely inserted and fixed so as to correspond to an operation shaft (hereinafter, referred to as a rod) that moves linearly by the operation of the solenoid.
