PURPOSE: A safety handle for a door lock is provided to set an unlocking prevention function to a door lock handle by a user, thereby preventing a locking device of the door lock even though the user discretionally unlocks the door lock handle in an indoor side. CONSTITUTION: A safety handle for a door lock includes a rod (104), a handle (100), a coupler insertion hole (108), a release button insertion hole (107), a coupler (111), and a release button (117). The rod includes square rods (102) on both end portions and a circular rod (103) between the square rods, thereby being inserted into a spinning port of the locking device. The handle includes a rod insertion hole (106), in which the rod is inserted, on the underside. The coupler insertion hole is connected to the rod insertion hole and formed on the top surface of the handle and includes a projection unit (109) and a groove (110) on the top surface. The release button insertion hole is formed on one side of the coupler insertion hole. The coupler having a square cross section includes a rod insertion hole (113) in which the rod is inserted on the lower side of a body (112); a coupling piece (114), which is inserted into the groove of the coupler insertion hole by being protruding toward the outer side, on the upper side of the body; and a projected piece (116) protruding to the outer side of a column (115) formed on the upper side of the body. The coupler is inserted into the coupler insertion hole. The release button includes a latch (119), in which the protruding piece of the coupler is inserted, on a side and is inserted into the release button insertion hole. |
