The invention belongs to the technical field of hinges, and particularly relates to a positioning door hinge. The positioning door hinge comprises a first hinge part and a second hinge part which are parallel to the rotating shaft. The outer wall of a shaft body of the first hinge part is provided with a first arc-shaped groove body, and the outer wall of a shaft body of the second hinge part is provided with a second arc-shaped groove body; wherein when the inner cambered surface of the first arc-shaped groove body and the second shaft body are concentrically arranged, the second hinge part can rotate with the second shaft body as the axis, and when the inner cambered surface of the second arc-shaped groove body and the first shaft body are concentrically arranged, the first shaft body can rotate, and the second shaft body cannot rotate. The door hinge has the function of fixing the door hinge at a specific angle while ensuring free rotation of the door hinge, and the door hinge is prevented from shaking or the door opening angle is prevented from being too large.
本发明属于铰链技术领域，尤其涉及定位门铰链。定位门铰链包括转动轴相平行铰链一部、铰链二部。铰链一部，其一部轴体的外壁具有一部弧形槽体，铰链二部，其二部轴体的外壁具有二部弧形槽体；其中，所述一部弧形槽体的内弧面与所述二部轴体同心设置时，所述铰链二部能够以二部轴体为轴转动，当所述二部弧形槽体的内弧面与所述一部轴体同心设置时，所述一部轴体能够转动且所述二部轴体无法转动。本发明在保证门页自由转动的同时，具有使门页固定在特定角度的功能，防止门页晃动或开门角度过大。
