The invention provides a rotary pushing type hydraulic hinge which comprises a fixed shaft sleeve and a rotating shaft, an oil cavity used for containing damping oil is formed in the fixed shaft sleeve, one end of the fixed shaft sleeve is matched with a sealing end cover, and the rotating shaft penetrates through the sealing end cover to be matched with a perturbing assembly located in the oil cavity and used for perturbing the damping oil. The perturbation assembly comprises a movable sleeve connected with the tail end of the rotating shaft and a piston matched with the movable sleeve, a wedge-shaped protruding part is formed on the movable sleeve, a wedge-shaped groove part is formed on the piston, a limiting groove is formed in the inner wall of the fixed shaft sleeve, a protruding edge is arranged on the outer wall of the piston, and a reset spring is further arranged between the piston and the bottom of the oil cavity of the fixed shaft sleeve. Compared with the prior art, when the rotating shaft in the damper rotates downwards, the movable sleeve on the rotating shaft rotates to push the piston to move in the fixed shaft sleeve, the damping oil in the oil cavity is extruded, and the rotating speed of the rotating shaft is reduced, so that the closing action of the cover plate is not influenced, slow descending can be realized, and the collision force is greatly reduced.
本发明提供一种旋推式液压铰链，包括固定轴套和转轴，固定轴套内设有用于盛装阻尼油的油腔，固定轴套的一端配合有密封端盖，转轴穿过密封端盖配合有处于油腔内用于挠动阻尼油的挠动组件，挠动组件包括与转轴的尾端部连接的活动套筒和与活动套筒配合的活塞，活动套筒上形成有楔形凸起部，活塞上形成有楔形凹槽部，固定轴套的内壁上设有限制槽，活塞的外壁上设有凸棱，活塞与固定轴套的油腔底部之间还设有复位弹簧。与现有技术相比，该阻尼器中转轴向下转动时，利用转轴上的活动套筒转动推动活塞在固定轴套内移动，挤压油腔内阻尼油，降低转轴转速，这样不影响盖板的关闭动作，并能缓慢下降，大大减少碰撞力度。
