PURPOSE: A hinge structure for a door is provided to reduce costs required for replacing components by coupling a third actuating link to a detachable connector and to improve abrasion-resistance and convenience. CONSTITUTION: A hinge structure for a door comprises a main plate(10), a first actuating link(20), a second actuating link(30), a third actuating link(40), a first mounting place(50), a second mounting place(60), and an elastic member. The main plate comprises a guide link(11). The first and second actuating links are coupled to both sides of the main plate and are folded. The third actuating link is hinge-coupled to the other end of the second actuating link and is folded. The first mounting place is hinge-coupled to the other end of the first and second actuating links. The second mounting place is hinge-coupled to the guide link and the other end of the third actuating link. The elastic member is located between the third actuating link and the second mounting place and provides bidirectional restoring force. |
