The present invention relates to a door hinge structure. According to the present invention, the door hinge structure comprises: a fixing bracket (110) wherein a first pin hole (112) is formed on a side; a pin (130) installed in the first pin hole (112); a seesaw unit (120) wherein a first plate (124) and a second plate (125) are respectively formed on both sides of a second pin hole (122) based on the pin hole (122), and the first and second plates (124, 125) perform a seesaw motion as the pin (130) is installed in the second pin hole (122); an elastic unit (140) installed between the first plate (124) and the fixing bracket (110), applying restoring force to the pushing direction of the first plate (124); and a shaft (160) wherein a contact surface (162) and an edge (164) are repeatedly and alternately formed on a side, being rotated with a door (20) together as the door (20) is opened and closed in a door frame (10). As the second plate (125) adheres to the contact surface (162), rotation of the door (20) is restrained and a state of the door (20) to be opened and closed maintained. |
