ABSTRACT:
A basketball frame structure includes a backboard, two fixing plates, a base, two first upright rods, two second upright rods, two first links, an adjusting bar, two second links, and a plurality of hollow weights. Thus, the height of the backboard is changed by movement of the adjusting bar, thereby facilitating a user adjusting the height of the backboard. In addition, when the adjusting bar is moved, the positioning bolt is slidable in the slideway of the adjusting bar and detachably locked in either one of the retaining slots of the adjusting bar, so that the height of the backboard is changed in a multi-stage manner so as to fit requirements of different users.
