The present invention relates to a door locking device, which comprises: a rotary shaft which is included in a door; a rotary unit which installs the rotary shaft on the door to be able to rotate; a rotary body which is included at the end of the rotary shaft and rotates along the rotary shaft; a handle unit which protrudes in one direction from the end of the rotary body in order to rotate the rotary body; a hanging unit which has a hanging protrusion and is formed on a door frame where the door is installed; and a hook unit which is formed on the rotary body in order to protrude in the same direction as the handle unit, in turn, rotates along the handle unit, and where a hanging groove opening to one side is formed at the end thereof in order to close the door by being hung on the hanging protrusion or to open the door by being separated from the hanging protrusion. The door locking device can open or close the door regardless of the type of a door such as a hanged door and a sliding door. When closing the door, the door locking device can protect the inside space by closing the door at a right angle to the door access direction so that the door cannot be opened by external pressure such as a strong wind and a typhoon. |
