<p>The present invention relates to a door hinge configured to more stably close a door. To this end, the door hinge according to the present invention includes: a fixed board fixed to the door frame; a cover housing fitted to the upper end of the fixed board; an operation cam member rotatably disposed within the cover housing, wherein the operation cam member is axially coupled to an operation frame fixed to the door so that the operation frame rotates with respect to a shaft according to the rotation of the operation frame; a link eccentrically coupled to one side of the operation cam member by using a second pin so that the link linearly operates according to the rotation of the operation cam member; a slide coupled to the link by using a first pin so that the slide moves in the forward, backward, and horizontal directions according to the linear movement of the link due to the rotation of the operation cam member in a state where the slide is disposed within the cover housing; and a spring fitted into the outer circumferential surface of the slide and pressed by the horizontal movement of the slide to elastically support the closing of the door.</p> |
