In order to achieve the above objects and effects, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a door lock according to an embodiment of the present invention, FIG. 2 is a perspective view showing a state in which an inner and outer grips are removed from the door lock according to the present invention, and FIG.

The door lock (1) according to the present invention has a structure in which a lock pin is located in a room, and can be locked and unlocked. When the door lock (1) is mounted on a door, And the device 6 is installed.

The door lock 1 includes a vertical plate 11 attached to a side surface of the door 15 and a vertical plate 11 attached to the side surface of the door 15 so that the latch unit body 2 is inserted do.

One side of the latch unit body 2 is coupled to the latch bolt 14 on one side and the unlocking block 12 on the other side of the latch 3 which is inserted into and pulled out from the vertical plate 11 into the door frame.

The latch bolt 14 is inserted and drawn out from the door frame in the latch unit 3 which is slidably operated in the left-right direction in association with the indoor / outdoor side knobs 9, 9 'inside the latch unit body 2.

A pair of knobs 9 and 9 'and a cover 10 interlocking with the latch 3 are positioned and coupled to the inside and outside of the door 15.

The latch 3 is positioned on the side surface of the latch unit body 2 of the door lock 1 and the latch 3 is provided on the front (outdoors) and rear (interior) The slide hole 5 is formed in a straight line with the latch 3 in a state in which the slide hole 5 is positioned so as to intersect the slide hole 5 and the hole.

Further, the emergency breaker device 6 located in the slide hole 5 is inserted in a state where the breaker block 12 and the spring 8 are engaged.

The detaching block 12 is exposed to the front and rear surfaces of the slide hole 5, and the detaching grooves 7 are integrally formed on the exposed front and back surfaces inward.

Therefore, the latch 3, the unlocking block 12, and the spring 8 are connected in a straight line, and the latch bolt 14 and the latches 3 are opened each time the door 1 is opened and closed by the indoor and outdoor knobs 9, , The freezing block 12 and the spring 8 interlock with each other and slide in the left and right direction.
