One end of the torsion spring 68 is fixed relative to the dead bolt opening and closing module 60, and the other end of the torsion spring 68 is fixed relative to the housing 20. The torsion spring 68 is applied to the handle 30 based on a specific position when the transfer 50 is rotated by the pressure applied to the handle 30 to rotate the dead bolt opening and closing module 60. The dead bolt opening and closing module 60 is provided to be easily moved to the open or closed position even if the external force is removed.

Hereinafter, the operation of the door lock device 10 of the present embodiment configured as described above will be described in detail with reference to the drawings shown in FIGS. 1 to 8.

First, it is assumed that the door lock device 10 according to the present invention is installed in the door. The description starts on the basis of the state shown in FIG. The door lock device 10 shown in FIGS. 1 and 5 assumes that both the dead bolt and the lock bolt are locked.

In this state, as shown in FIG. 3, an external force F is applied to the handle 30 to push the upper end of the handle 30 toward the door. The handle 30 is finely rotated with respect to the housing 20 about the lower end of the handle 30 as an axis. The digital door lock device 10 in the portion facing the door side at this time is shown in FIG. In this case, the pressing pin 34 rotates the transfer 50 finely, but the dead bolt opening and closing module 60 has not been operated. In addition, the open bar 40 connected to the guide member 36 and the handle stator 46 is in a state of little movement yet.

As shown in FIG. 4, when the handle 30 is compressed to the maximum displacement by applying an external force F to the handle 30, the pressing pin 34 is transferred as shown in FIG. 7. By rotating the 50, the dead bolt opening and closing module 60 coupled to the transfer 50 dependently is rotated so that the dead bolt is released. In addition, the handle 30 presses the handle stator 46, and the open bar 40 rotates about the rotational shaft 44 so that the free end of the open bar 40 flows freely. The lock bolt connected to the end is released. So, when the door is pushed in the state shown in Figs. 4 and 7, the dead bolt and the lock bolt are released so that the door is opened.

As described above, the door lock device 10 according to the present invention is innovative compared to the conventional door lock device because the dead bolt and the lock bolt are released only by pushing the handle 30 in the process of opening the door indoors and moving out to the outdoor side. Improved opening and closing function. When a person closes the door after leaving the outdoor side, the handle 30 moves to the original position by the elastic restoring force of the compression coil spring 38, and the open bar 40 is returned to its original position by the elastic restoring force. As it moves, the lock bolt is locked. However, the dead bolt opening and closing module 60 is kept locked by the torsion spring 68 so that it is not locked. In order to close the dead bolt opening and closing module 60, an additional process such as inserting and turning a key into a keyhole is required.

In the above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made by those skilled in the art within the technical idea of the present invention.
