Abstract
A case hinge structure is adapted for installing on a case which includes a case body having a rear panel and a case cover having a rear wall wherein the hinge structure is affixed between the rear panel of the case body and the rear wall of the case cover in such a manner that the case cover is adapted for pivotally folding from a closed position to an open position. In the closed position, the case cover is tightly cover on top of the case body, and in the open position, the case cover is pivotally folded up at a predetermined folding angle with respect to the case body. The hinge structure includes a lower joint, which is affixed to the rear panel, including a supporting arm having a C-shaped cross-section and defined a mounting slot therein, and an upper joint, which is affixed to the rear wall, having a pivot arm rotatably and coaxially received in the mounting slot of the lower joint in such a manner a mutual friction is provided between an outer circumferential surface of the pivot arm and an inner circumferential surface of the supporting arm, so as to frictionally adjust the folding angle of the case cover when opening the case.
