Connected manual rotation pin 7 is reversed rotation.

Therefore, the dead rotation shaft 22 is coupled to the manual rotation pin 7 is fitted, the dead cam 23 coupled with the dead rotation shaft 22 by the dead cam stopper 26 is rotated while the dead cam The dead rod 24 protruding from the outside of the 23 is separated from the open support groove 28b and seated in the closed support groove 28a while rotating counterclockwise, and the dead plate 27 is advanced by the continuous rotation. As a result, the dead bolt 11 and the latch 13 protrude out of the electrical box 9 and are inserted into the dead groove 51 of the door frame 50 to return to the initial locked state.

At this time, when the dead bolt 11 and the latch 13 is rotated to the outside of the electrical box 9, the inner handle 8, the dead bolt 11 and the latch 13 is again the electrical box It is drawn into the inside of the (9), but the dead bolt (11) and the locking bolt (13) is reversed in the direction of rotation of the stationary motor (6) rotated in the direction to protrude to the outside of the electric box (9) dead bolt (11) ) And the latch (13) to the inside of the electric box (9) by using a method of suddenly changing the direction of rotation of the stationary motor (6), so many gears (not shown) coupled with the stationary motor (6) There was a problem that the risk of failure is high due to the load.

However, according to the present invention, the dead bolt operating portion 20 for operating the dead bolt 11 and the latch 13 irrespective of the driving of the stationary motor 6 even if the inner handle 8 is rotated as described above. Is operated in conjunction with the latch bolt operating portion 30 is connected by the inner handle (8) and the latch operating rod (14), so that the stationary motor (6) and the gear does not become excessive, thereby reducing the risk of failure. .

On the other hand, since the Hall sensor 42 is already commercialized, it is not only easily purchased and used on the market, but the present invention does not relate to the internal structure of the Hall sensor 42. I will omit it.

Although the above-described embodiments have been described with respect to the most preferred embodiments of the present invention, it is apparent to those skilled in the art that the present invention is not limited to the above embodiments, and various modifications can be made without departing from the technical spirit of the present invention. will be.

According to the electric lock having an automatic locking function according to the present invention configured as described above, the dead bolt operating unit for operating the dead bolt is configured to be interlocked by the latch bolt operating unit for operating the latch bolt to open the door from the inside of the door. When opening, the door can be opened only by the rotation of the inner handle irrespective of the double locking state, so that even if other parts of the door lock device are damaged in the event of an emergency such as a fire, it can be quickly evacuated to the outside by only the rotation of the handle.

In addition, according to the present invention by installing a boomerang-shaped clasp that is operated at the same time as the dead bolt in the dead bolt to prevent the dead bolt is pushed in by the forced force from the outside so that the door is not opened to improve the security. It has an additional effect that can be made.

In addition, according to the present invention, the dead bolts are automatically locked and released by the forward and reverse rotation of the forward and reverse motors, thereby smoothly operating the dead cams and the dead cams having the dead rods coupled to the dead bolts, and artificially forcing the dead bolts.
