A push-pull digital door locking device is disclosed. An embodiment of the present disclosure comprises: a housing which is installed at one side or two sides of a door and includes a key input unit through which a password is inputted; a handle unit which is installed in the housing to be locally movable; a first locking device which is coupled to the handle unit to locally move when the handle unit locally moves, and converts a direction of force acting on the local movement into a direction vertical to the direction of the local movement to perform a door opening/closing action; a control unit which receives and compares the password inputted through the key input unit with a preset password, and transmits a driving signal if the two passwords match up with each other; a driving unit which receives the driving signal of the control unit to drive; and a second locking device which is locally moved in the direction vertical to the direction of the local movement of the handle unit by force transmitted by the rotation of the driving unit, so as to perform a door unlocking action. According to the present invention, it is possible to simplify a structure of the door locking device by a sliding unit which locally moves by force transmitted when the handle unit locally moves, and a sliding guide unit which enables a locking/unlocking operation of a latch unit by converting a direction of force generated when the sliding unit locally moves into a direction vertical to the direction of the local movement of the sliding unit. Thus, it is possible to reduce the number of parts, to improve productivity by simple assembling, and to reduce the unit price of a product. |
