Hydraulic shaft core with single-side slotted hidden hydraulic hinge
The invention relates to the technical field of door and window accessories, in particular to a hydraulic shaft core of a unilateral slotted hidden hydraulic hinge, which comprises a shell, a piston rod unit capable of reciprocating is arranged in the shell, one side of the piston rod unit is sleeved with a short spring unit, a first hydraulic oil cavity is formed between the piston rod unit and the short spring unit, and a second hydraulic oil cavity is formed between the piston rod unit and the short spring unit. An adjustable valve element unit is inserted into the end, away from the short spring unit, of the piston rod unit, a second hydraulic oil cavity is formed between the adjustable valve element unit and the piston rod unit, and the short spring unit can be squeezed towards the piston rod unit to reduce the space of the first hydraulic oil cavity. The hydraulic shaft core can prevent switching failure of hydraulic oil between the two hydraulic cavities, so that the phenomenon that the buffering effect is not obvious or fails is prevented, the traditional step of installing a hinge according to the specified direction does not need to be adopted, and the hinge can adapt to various door bodies.
本发明涉及门窗配件技术领域，具体公开了一种单边开槽暗藏液压合页的液压轴芯，所述壳体，所述壳体内设置有可往复移动的活塞杆单元，所述活塞杆单元的一侧套接有短弹簧单元，所述活塞杆单元和短弹簧单元之间形成第一液压油腔，所述活塞杆单元远离短弹簧单元的一端插接有可调节阀芯单元，所述可调节阀芯单元与活塞杆单元之间形成第二液压油腔，所述短弹簧单元能够向活塞杆单元方向挤压，以缩小第一液压油腔的空间；该液压轴芯可以防止液压油在两个液压腔之间切换失效，从而防止缓冲效果不明显或失效的现象，不需要采用传统的按指定方向安装合页的步骤，使得合页可以适应多种门体。
