Heavy door hinge with self-return function
The invention relates to the field of heavy door hinges, and discloses a heavy door hinge with a self-return function, which comprises a first hinge seat, mounting holes are respectively formed in the inner bottom surface and the inner top surface of the first hinge seat, and a hinge rotating arm is rotatably arranged in the first hinge seat; first gears are fixed to the top face and the bottom face of the hinge rotating arm correspondingly, a rotating column is rotatably arranged between the two fixing grooves, two second gears are arranged on the outer wall of the rotating column, and torsional springs are fixed to the top face of the upper second gear and the bottom face of the lower second gear correspondingly. And a second hinge seat is detachably arranged on one side of the hinge rotating arm. According to the heavy door, after the heavy door is opened, the heavy door has a self-returning function, automatic closing is facilitated, the safety risk caused by negligence or forgetting to close the door is reduced, meanwhile, the requirement for manually closing the door by workers is eliminated, and the operation convenience of the heavy door is improved.
本发明涉及重型门铰链的领域，公开了一种具有自回功能的重型门铰链，包括第一铰链座，所述第一铰链座的内部底面、顶面分别开设有安装孔，所述第一铰链座的内部可转动的设置有铰链转臂，所述铰链转臂的顶面、底面分别固定有第一齿轮，两个所述固定槽之间可转动的设置有转动柱，所述转动柱的外壁设有两个第二齿轮，上方的所述第二齿轮的顶面与下方的第二齿轮的底面分别固定有扭簧，所述铰链转臂的一侧可拆卸的设置有第二铰链座。在本发明中，当重型门在打开后，具有自回功能，利于进行自动关闭，减少了因疏忽或忘记关闭门而引起的安全风险，同时消除了工作人员手动关闭门的需要，提高了重型门的操作便捷性。
