The coupling groove 460 to which the lower side bar 514 of the rotating shaft 506 is coupled is formed with both side edges inclined. This is to prevent the dead bolt 458 from being locked by the external force.

Therefore, the dead bolt 458 is operated only by the operation of the drive motor, not shown, only by the operation of the key or the operation of the key button 204.

The latch bolt 446 is moved by a latch link 452 having a protrusion 454 connected to the coupling groove 448.

At this time, as the guide plate 496 connected to the sliding plate 484 moves, the side plate of the guide plate 496 and one side end of the latch link 452 are fixed to the door frame in a state where the latch bolt protrudes.

Operation of the door lock device of the present invention configured as described above is as follows.

First, in a state where the locking state is not made, the rotary plate 476 is positioned horizontally, and the end portion of the locking unit 400 which contacts the dead bolt 458 of the rotation shaft 506 is located inward and the guide plate 496 is located backward. It is located.

The latch bolt 446 is inserted in a state in which the latch link 452 and the guide plate 496 are separated from each other by a predetermined distance.

At this time, when the external handle 208 is rotated, the first rotating rods 220 and 222 and the rotating plate 476 rotate, thereby lowering the sliding plate 484 while sliding downward.

The door locking device 100 configured as described above automatically operates when the door is closed because the safety device operates to prevent the door from being opened outside when the door is closed.

In addition, if you press the open button in the indoor video phone can be opened from the inside, it is easily compatible with the existing video phone does not require the need for modification.

Meanwhile, two methods may be used to lock the door by using the door locking device 100.

The first is manual and the second is electric.

First, in the manual method, when the key is inserted into the key groove 210 and rotates, the key shaft 224 rotates, and as the key shaft 224 rotates, the rotation shaft 506 of the locking unit 400 rotates together, and simultaneously the driving unit. The gearbox of 300 is operated so that the dead bolt 458 connected to the gearbox protrudes laterally to approach the coupling groove formed in the door frame. At this time, as the rotating shaft 506 rotates, the guide plate 496 is upward, and portions where the guide plate 496 and the latch link 452 contact each other are separated from each other.

Accordingly, even when the outer handle 208 is rotated, the latch bolt 446 does not operate and continues to be coupled to the door frame.

Therefore, the locked state of the door is to maintain the double locked state by the latch bolt 446 and the dead bolt 458.

Subsequently, when the door is locked using the electric method, when the first door lock device 100 is not operated and the key button 204 of the operation unit 200 is pressed to input a password, the driving motor of the driving unit 300 is It is rotated, the gear box geared to the drive motor is operated to rotate.

As the gearbox operates, the key shaft 224 connected to the gearbox is rotated, and the dead bolt 458 protrudes by the rotation of the key shaft 224 from the lock portion 400 to maintain the locked state. At this time, the operation of the locking unit 400 is the same as described above.

And, if you want to release the lock state of the door by pressing the key button 204 of the operation unit 200 to enter a password, the drive motor of the drive unit 300 is rotated in reverse, thereby causing the key shaft 224 to reverse rotation The dead bolt 458 of the locking unit 400 enters the locking unit body 402 to release the locked state.

At this time, as the guide plate 496 is downward, the latch link 452 and the guide plate 496 are in contact with each other, so that the latch bolt 446 may also be operated by the operation of the external handle 208.

The present invention described as described above is not limited to the preferred embodiment as described above, it is common in the art to which the present invention belongs without departing from the spirit of the present invention claimed in the claims of the present invention Those skilled in the art will be able to perform various modifications, as well as such modifications will be within the scope of the claims described as key elements of the present invention.

As such, the door lock device of the digital door of the present invention has the advantage that the durability life of the digital door is improved by being configured to be used for a long time with less power, the precision is easy to assemble and the productivity is improved. .

In addition, the present invention has the effect of preventing the exposure and leakage of the password by double-pressing the key button when setting the password, and can be easily installed in the existing door, so the consumer can install it directly, the cost is low It works.
