Abstract
Disclosed herein is a locking device of a hinged door. The locking device of the hinged door according to the present invention comprises a trapping part and a fixing part selectively mounted on the hinged door and a door frame and slidly trapped mutually to open the hinged door only at regular intervals. The fixing part comprises a bracket and a clamp rotatably coupled to the bracket. A clamp is partly moved up and down by coupling a trapping means to a keyway connected to a hinge of the bracket. The clamp is supported toward upper parts to maintain a trapping state of the trapping means at the keyway and then limiting a rotation of the clamp. If the trapping means leaves the keyway by a pressure of the hinge of the bracket, the clamp is rotated at the bracket.
