PURPOSE: A door locking device is provided to prevent a dead bolt from being separated from a dead bolt insertion hole when a door is physically hacked. CONSTITUTION: A door locking device comprises a housing(10), a dead bolt, and a latching member. The housing is installed on a door. The dead bolt is installed inside the housing to move in a straight line. An inclined part(21), a hanging groove(22), and a movable space part are formed in the dead bolt. The dead bolt is inserted into or released from a dead bolt insertion hole. The dead bolt is hung on the hanging member which prevents the linear movement of the dead bolt. The hanging member is moved from the releasing position to the insertion position.
