The invention discloses an automatic reset buffer door hinge, which can effectively increase the bearing weight and enable the rotation of the door hinge to be smoother through the design of balanced stress of a three-blade sleeve and combined rotation of three ball bearings. And meanwhile, the pressure spring and the spring type single valve are arranged, so that the door hinge can be automatically reset, and a better buffering effect is achieved.
本发明公开一种自动复位缓冲门铰，通过三叶套均衡受力和三个滚珠轴承联合转动的设计，能有效在加大承载重量的同时使门铰转动更为顺滑。同时压力弹簧的设置和弹簧式单阀门的设置能够使门铰自动复位并达到更好的缓冲效果。
