具有缓冲功能的门铰链
摘要：
本发明涉及一种具有缓冲功能的门铰链，特点是包括外壳、第一及第二转轴、“U”型转轴、铰链杯、连动件、扭力弹簧及连接件、支撑结构及缓冲结构；其中连动件一端通过第一转轴转动的设在外壳内，另一端通过“U”型转轴的一轴与铰链杯转动连接；连接件的一端通过第二转轴转动的设在外壳内，另一端通过“U”型转轴的另一轴与铰链杯转动连接，扭力弹簧套设在第二转轴上，扭力弹簧的一端固定在连动件上，另一端抵靠在连动件上；支撑结构固定在连动件上；缓冲结构承托在支撑结构上并随支撑结构在外壳内运动，缓冲结构的活塞杆可抵靠在扭力弹簧上从而增加扭力弹簧复位的阻力。其优点为：结构简单，使用寿命长，方便维修，精度高。
摘要（英）：

A door hinge having a damping function, comprising a housing, a first rotating shaft, a second rotating shaft, a U-shaped rotating shaft, a hinge cup, a linkage member, a torsion spring, a connector, a supporting structure, and a damping structure; one end of the linkage member is rotationally provided in the housing by means of the first rotating shaft, and the other end of the linkage member is rotationally connected to the hinge cup by means of one arm of the U-shaped rotating shaft; one end of the connector is rotationally provided in the housing by means of the second rotating shaft, and the other end of the connector is rotationally connected to the hinge cup by means of the other arm of the U-shaped rotating shaft; the torsion spring is fitted over the second rotating shaft.
