ABSTRACT:
A hinge structure includes a pivot shaft, a knuckle receiving the pivot shaft rotatably therein, and a disc locking mechanism. The knuckle has a front-end face formed with a retention recess. The locking mechanism includes a positioning disc disposed adjacent to the front-end face of the knuckle to permit extension of the pivot shaft therethrough, and having an inner surface facing the front-end face and formed with a reception recess. The positioning disc is rotatable simultaneously with the pivot shaft. A roller is sandwiched between the front-end face and the positioning disc in such a manner to engage the retention recess and the reception recess when the retention recess is aligned with the reception recess, thereby preventing rotation of the pivot shaft in the knuckle.
