The present invention relates to a hinged door locking device and, more particularly, to a hinged door locking device comprising a rotatable lever installed on a door frame separately from a main locking device generally used for security, wherein a side to be opened by rotation in the hinged door is brought into tight contact with the door frame at multiple points in the longitudinal direction by operating the lever. Thus, the hinged door locking device is configured to readily maintain the tight contact and has high usability as an auxiliary locking device. 11111ba. A locking device of a hinged door () installed between a rotation opening side of the hinged door () , which is installed in a door frame using a door hinge () installed on one side of the door frame , and a door frame () , the locking device comprising:{'b': 130', '1, 'a plurality of close contact guide plates () installed on the rotation opening side of the hinged door () to be separated from each other in a longitudinal direction;'}{'b': 120', '1', '1', '130', '1', '1', '1', '1', '1', '130, 'i': a', 'a', 'a', 'a, 'a plurality of pressure rolls () configured to achieve a compressed locked state by pulling the rotation opening side of the hinged door () toward the door frame () while in contact with the close contact guide plates () in a state in which the rotation opening side of the hinged door () is closed on the door frame () and configured to be installed on the door frame () to be separated from each other in the longitudinal direction to achieve the uncompressed locked state between the rotation opening side of the hinged door () and the door frame () in a noncontact state with the close contact guide plates ();'}{'b': 110', '110', '1', '120', '1', '120, 'i': a', 'a', 'a, 'a driving plate () installed in the sliding pocket (), provided in the door frame () in the longitudinal direction so that the pressure rolls are slidably installed on the door frame () in the longitudinal direction, and ...
