The invention provides a hydraulic hinge with an improved structure, and belongs to the technical field of hinges. The problem that door opening is strenuous due to the fact that a torsional spring and an oil cylinder generate resistance at the same time is solved. According to the hydraulic hinge of the improved structure, a movable rod is slidably connected into an iron pipe oil cylinder, a main shaft comprises a thin shaft section and a thick shaft section, a first through hole is formed in a long rod part of the movable rod, a spiral groove penetrating through the thick shaft section is formed in the thick shaft section, a shaft sleeve sleeves the outer side of the main shaft, and the spiral groove and the first through hole penetrate through the middle of a second rolling needle; a rotating disc sleeves the outer side of the main shaft, symmetrical second sliding grooves are formed in the right part of the rotating disc, symmetrical guide grooves are formed in a third sliding cavity, first rolling needles are arranged between the guide grooves and the second sliding grooves, a copper coil is fixed to the left end of the main shaft, and a spring sleeves the outer side of the main shaft. The hydraulic hinge with the improved structure has the advantages that when the door is opened, the torsion spring can provide power to counteract part of resistance of hydraulic oil movement, so that the door is convenient to open, and when the door is closed, the torsion spring and the hydraulic oil both provide resistance to buffer the door.
本发明提供了一种改良结构的液压合页，属于合页技术领域，它解决了由于扭簧和油缸同时产生阻力，使得开门比较费力的问题。本改良结构的液压合页，铁管油缸的内部滑动连接有活杆，主轴包括细轴段和粗轴段，所活杆的长杆部开设有第一通孔，粗轴段开设有贯穿粗轴端的螺旋槽，主轴的外侧套设有轴套，所述滚针二的中部贯穿螺旋槽和第一通孔，主轴的外侧套设有转盘，所述转盘右部开设有对称的第二滑槽，第三滑腔内开设有对称的导向槽，所述导向槽与第二滑槽之间设置有滚针一，主轴的左端固定有铜卷，主轴的外侧套设有弹簧。本发明具有的优点是，开门时，扭簧会提供动力，抵消一部分液压油运动的阻力，从而使得开门便捷，关门时，扭簧和液压油均提供阻力，实现对门的缓冲。
