At this time, the end of the shaft 320 is sensed by the limit switch 400, so as to fall from the limit switch 400 in accordance with the movement of the shaft 320 confirms whether the dead bolt 340 protrudes.

Therefore, the magnetic sensor 600 confirms whether the door 10 is closed and the dead bolt 340 is locked when the door 10 is correctly closed, and then checks whether the dead bolt 340 is locked. By doing so, the reliability of security and security is improved.

And, as shown in FIG.

When the magnetic force of the solenoid 310 is broken, the shaft 320 is received into the shaft accommodating groove 311 of the solenoid 310 while moving backward, and is spaced apart from the dead bolt 340 held while the shaft 320 moves backward. The dead bolt 340 is released from the dead bolt insertion hole 121 of the door plate 100 with the restoring force of the spring 360 is accommodated as the dead bolt guide hole 331 of the intermediate block 330, the door 10 ) Opens.

At this time, the end of the shaft 320 moved back is detected by the limit switch 400 to confirm whether the door is opened.

As described above, since the structure is simple and the operation means 300, the limit switch 400, and the magnetic sensor 600 are all accommodated in the housing, the design is compact and the power lines to be drawn out can be neatly arranged so that the appearance is beautiful. In addition, manufacturing costs can be saved due to reduced parts.

Although the present invention has been shown and described with reference to certain preferred embodiments, the present invention is not limited to the above-described embodiments, and the general knowledge in the art to which the present invention pertains falls within the scope of the present invention. Various alternative changes and modifications will be possible by the possessor.

As described above, the present invention allows the dead bolt to be locked when the door is correctly closed, thereby maximizing crime prevention and security, and the structure is simple, thereby saving manufacturing costs due to reduced parts, and installing work. This facilitates shortening of the working time, thereby improving the reliability of the product.

In addition, it has a compact design and neatly organizes the power lead wires by accommodating both the operation means of the electromagnet door lock, the magnetic sensor to detect whether the door is opened and closed, and the limit switch to detect whether the dead bolt is locked in the housing. Therefore, there is an effect of improving the merchandise of the product.
