As a cross-sectional view, (A) is an operating state diagram showing the operating means when the door is opened, (B) is an operating state diagram showing the operating means when the door is locked, Figure 4 is a dead bolt type according to the present invention The state of use of the electromagnetic door lock is shown, respectively.

As can be seen from the present invention is provided with a permanent magnet 110 and the dead bolt insertion hole 120 is provided with a door block 100 is fixed to the door 10; The housing 210 is provided therein, a dead bolt guide hole 220 is provided on one side of the receiving portion 210, the housing is provided with a magnetic accommodation groove 230 on the outer circumference of the dead bolt guide hole 220 200; The solenoid 310 seated on the receiving portion 210 of the housing 200 and driven according to an electrical signal, the shaft 320 to operate in accordance with the drive of the solenoid 310, and the shaft 320 of the The working piece 340 coupled to the tip 330 and rotated according to the operation of the shaft 320, and accommodated in the dead bolt guide hole 220, protrudes to the outside according to the rotation of the working piece 340, and the inside thereof. An actuating means (300) provided with a dead bolt (350) accommodated in the spring and a spring (360) inserted into an outer circumferential surface of the dead bolt (350) to provide a restoring force; A limit switch 400 provided at a lower portion of the operating piece 340 to detect rotation of the operating piece 300 to check whether the dead bolt 350 is projected; A magnetic sensor 500 provided in the magnetic accommodating groove 230 of the housing to check whether the door 10 is opened or closed through the permanent magnet 110 of the door block 100; The dead bolt 350 of the operating means 300 is provided with a dead bolt through-hole 610 is made of a cover plate 600 to cover the housing 200.

Here, the housing 200 is provided so that the receiving portion 210 and the dead bolt guide hole 220 are passed through each other so that the operating means 300 are all settled inside the housing 200, and one side at a square corner. The cover plate 600 is coupled to each other and has a coupling hole 250 penetrating through the housing 200 so that the door frame 20 is coupled to the other side. Equipped.

The solenoid 310 settled in the receiving portion 210 of the housing 200 has a receiving groove 311 at the center of one side, and the shaft 320 is inserted into the receiving groove 311 so that It operates before and after depending on driving.

The operating piece 340 coupled to the tip of the shaft 320 at the pin 330 has an operating bar 341 at the upper side, and a hinge portion 342 coupled to one end of the housing 200 at the lower side. The other side of the lower portion includes a guide groove 343 inclined vertically by a predetermined angle, such that the pin 330 provided at the tip of the shaft 320 is coupled to the guide groove 342.

One of the bottom of the receiving groove 311 of the solenoid 310 in contact with the rear end of the shaft 320 and the rear end of the shaft 320 is provided with a residual magnetic removing body 370 made of a non-magnetic material.

The residual magnetic eliminator 370 is to remain in the rear end surface of the receiving groove 311 of the solenoid 310 or the shaft 320 is bonded to the solenoid 310 when the magnetic force is cut off by blocking the electrical signal to the solenoid 310 when the door is opened This is to improve the factors that can be mistaken for the malfunction of opening door by removing residual magnetic force.

If the non-magnetic material, such as aluminum, synthetic resin, copper, etc. of the residual magnetic removing body 370, it is preferable to provide a stainless material in order to prevent wear.

The dead bolt 350 is preferably provided in a hollow form that the interior is empty so that the drive is made even with less electrical energy.

In addition, the door frame plate 700 coupled to the rear surface of the housing 200 and fixed to the door frame 20 may be further provided.

The door frame plate 700 may be provided in a "-" shape or an "L" shape, and has a coupling hole 730 corresponding to the coupling hole 250 of the housing 200 at a square corner, and a rear surface thereof. The outlet hole 240 and the outlet port 710 corresponding to the outlet port 710 is provided at both ends, and the insertion hole 720 for receiving the power line drawn out to the outlet port 710 has the outlet port 710 of each side end. It is provided in the longitudinal direction to communicate.

Therefore, the outlet 710 and the fastening hole 730 of the door frame plate 700 corresponds to the outlet hole 240 and the coupling hole 250 of the housing 200 even if the door frame plate 700 is changed in the left and right directions. It is easy and can arrange power lines in any form neatly.

Referring to the operation of the present invention made of the above configuration as follows.

First, the door block 100 is mounted on the door 10, and the housing 200 is mounted on the door frame 20 and fixed thereto.

At this time, the housing 200 may be fixed to the inside of the door frame 20 to be mounted and fixed, and also to couple the housing 200 to the door frame plate 700 and to fix the door frame plate 700 to the door frame 20. It may be.

As shown in (a) of FIG. 3, when the door 10 is closed, the permanent magnet 110 provided in the door block 100 is detected by the magnetic sensor 500 provided in the housing 200 and the door ( 10 is closed and the shaft 320 is pulled while being bonded to the solenoid receiving groove 311 as a magnetic force generated when power is applied to the solenoid 310 by an electrical signal.

As the shaft 320 is pulled into the accommodating groove 311, the pin 330 provided at the tip of the shaft 320 is guided to the guide groove 343 of the operating piece 340, along the shaft 320. At the same time as moving in the direction of movement of the shaft 320, the operating piece 340 is rotated by a predetermined angle around the hinge portion 342, the operating bar 341 pushes the dead bolt 350.

The dead bolt 350 protrudes from the dead bolt guide hole 220 of the housing and is inserted into the dead bolt insertion hole 120 of the door block to lock the door.

In addition, the rotated working piece 340 is detected by the limit switch 400 to confirm whether the dead bolt 350 is projected.

Therefore, the magnetic sensor 500 checks whether the door 10 is closed and the dead bolt 350 is locked when the door 10 is correctly closed, and then checks whether the dead bolt 350 is locked. By doing so, the reliability of security and security is improved.

And, as shown in (b) of FIG. 3, when the door is confirmed by the card input, fingerprint or password input when the door is opened, the electric signal is cut off to turn off the power of the solenoid 310.

When the magnetic force of the solenoid 310 is cut off, the shaft 320 protrudes while being spaced apart from the bottom of the receiving groove 311 of the solenoid 310, and the pin 330 provided at the tip of the shaft 320 is operated by the work piece 340. The guide bolt (343) of the (3) is moved to return the operating piece (340) and the operating bar (341) is moved away from the dead bolt (350) while pressing the dead bolt 350 is the spring (360) Out of the dead bolt insertion hole 120 of the door block 100 with the restoring force of the received by the bolt bolt guide hole 220 of the housing is to open the door (10).

As described above, since the structure is simple, the operation means 300, the limit switch 400, and the magnetic sensor 500 are all accommodated in the housing, so the design is compact and the power lines to be drawn out can be neatly arranged to have a beautiful appearance. In addition, manufacturing cost can be saved due to reduced parts.
