The invention discloses a buffering safe automatic door closing hinge which comprises a fixed seat, a movable seat hinged to the fixed seat, an elastic piece arranged in the fixed seat, a damping piece arranged in the movable seat and a connecting piece connected with the elastic piece and the damping piece. The connecting piece comprises a connecting head hinged to the fixing base, a connecting rod connecting the elastic piece and the connecting head, and a damping connector connecting the damping piece and the connecting head. A first connecting shaft is arranged between the connector and the fixing base, a second connecting shaft is arranged between the connector and the connecting rod, a third connecting shaft is arranged between the connector and the damping connector, and the distance between the first connecting shaft and the second connecting shaft is smaller than that between the first connecting shaft and the third connecting shaft. When the connector rotates around the first connecting shaft, the motion trail of the second connecting shaft is not parallel to the motion trail of the third connecting shaft, and the stroke of the damping piece is larger than that of the elastic piece, so that the reliability of the damping piece is improved, the service life of the damping piece is prolonged, buffering door closing is achieved, and the door closing safety is improved.
本发明公开了一种缓冲安全自动关门合页，包括固定座、与固定座铰接的活动座、设于固定座内的弹性件、设于活动座内的阻尼件、以及连接弹性件及阻尼件的连接件；连接件包括与固定座铰接的连接头、连接弹性件及连接头的连杆，以及连接阻尼件及连接头的阻尼接头；连接头与固定座之间设有第一连接轴，连接头与连杆之间设有第二连接轴，连接头与阻尼接头之间设有第三连接轴，第一连接轴与第二连接轴的距离小于第一连接轴与第三连接轴的距离。本发明使得连接头绕第一连接轴转动时，第二连接轴的运动轨迹与第三连接轴的运动轨迹不平行，阻尼件的行程比弹性件的行程大，从而提升阻尼件的可靠性及使用寿命，实现缓冲关门，提高关门的安全性。
