The invention discloses a buffering safe automatic door closing hinge which comprises a fixed seat, a movable 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. The connector is a bent plate. 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 connector is a bent plate and comprises a short edge and a long edge, interference between the connector and the fixed seat and the movable seat during rotation is avoided, the reinforcing ribs are arranged between the short edge and the long edge, and the connection strength of the connector 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、活动座、设于固定座内的弹性件、设于活动座内的阻尼件、以及连接弹性件和阻尼件的连接件；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；连接头为弯折板。本发明的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；连接头为弯折板且包括短边和长边，避免连接头转动时与固定座和活动座发生干涉，短边和长边之间设有加强筋，提高了连接头的连接强度。
