DOOR HINGE.

Abstract

The present description pertains to the technical field of hinges and provides a door hinge. A hinge seat in this hinge has a first adjusting mechanism that moves back and forth along an installation direction, and a hinge core is located on one side of the first adjusting mechanism. The first adjusting mechanism is provided in a fixed manner with a second adjusting mechanism and a third adjusting mechanism, and the hinge core, the second adjusting mechanism, and the third adjusting mechanism move simultaneously with the first adjusting mechanism. The hinge core includes a core portion, a first adjusting portion, and a second adjusting portion, wherein the first adjusting portion is located at one end of the core portion away from the first adjusting mechanism, and the second adjusting portion is located outside the core portion.The second adjustment mechanism drives the second adjustment part to rotate, where the second adjustment part rotates to drive the core part to move along a direction perpendicular to a plane where the first adjustment mechanism is located, and the third adjustment mechanism drives the first adjustment part to rotate. Therefore, the present description has the advantages of a compact structure and smaller volume, and can be readjusted in the vertical and horizontal directions after assembly, and the preload angle can also be adjusted.
