PURPOSE: A door locking device is provided to lock a hinged door without an extra locking unit and to conveniently unlock the door with fully opening the door. CONSTITUTION: A door locking device (100) includes a fixing body (10), a door body (20), a latch (30), and a presser (40). The latch on a rotary shaft (50) guides the door body to rotate in one direction. When a door is fully opened, the presser rotates the latch with the door body so that the function of the latch is instantaneously eliminated. A gear part is formed at one side of the door body, and protrusions at the latch are engaged with the gear part. |
