BALL HINGE STRUCTURE

摘要

Provided is a ball hinge structure in which a ball hinge can be freely rotated in various directions and maintain a fixed state. The ball hinge structure includes a ball hinge rotatably installed in a hinge housing; and a first hinge resistor and a second hinge resistor elastically supported with respect to each other by a second spring, wherein the second hinge resistor is closely attached to a circumference at a side of a sphere of the ball hinge, the first hinge resistor is elastically supported by a first spring provided on a top surface of a hinge housing cap coupled to a lower portion of the hinge housing, and a groove is formed in the bottom of the ball hinge, and thus the first hinge resistor is lifted in a position as high as the height of the groove.
