PURPOSE: A stopper device installed on a hinge is provided to prevent a door from closing due to external factors since a stopper device is installed on a hinge, which connects the door to a door frame. CONSTITUTION: A stopper device installed on a hinge comprises a rotating unit(22), a first protrusion(26), a spring(28), a fixing unit, a guide groove(32) and a second protrusion(36). The rotating unit is coupled to the rotating plate(16) of a hinge(10) and rotates with the rotating plate. The first protrusion is inserted into the groove on the lower circumferential surface of the rotating unit to be able to move up and down. The spring is inserted into the groove of the rotating unit and elastically supports the vertical movement of the first protrusion. The fixing unit is fixed to the fixing plate(12) of a hinge. |
