PURPOSE: A door hinge is provided to stably close a door by preventing the drastic closing of a door by interfering the operation of an operating cam using the torsional force generated in a compressed spring. CONSTITUTION: A door hinge(10) comprises a shaft(20), a compressed spring(30), a cam member(40), a first actuating cam member(50) and a second actuating cam member(60). The shaft is combined in a door(D) and is revolved according to the opening and closing operation of the door. The compressed spring is inserted in the external diameter of the shaft. The cam member is inserted in the external diameter of the shaft and maintains a fixed stated without the rotation. The first actuating cam member is rotatably inserted in the external diameter of the shaft. The second actuating cam member is located between the cam member and door and is inserted in the external diameter of the shaft. |
