Description

Technical Field

[0001] The utility model relates to the technical field of hinge oil cylinders, in particular to a hinge oil cylinder and a base thereof. Background Art

[0002] A small cylinder (damper) is often used on hinges. The damping effect of the cylinder slows down the speed of the hinge from the open state to the closed state, so that the door panel connected to the hinge closes slowly. The piston of the cylinder is slidably connected to the inner wall of the cylinder body using a sealing ring. The common structure is to open an integrally formed annular groove on the tail end of the piston, and then insert the sealing ring into the annular groove.

[0003] Currently, when using a hinge oil cylinder, most of them use screws to fix the hinge oil cylinder so that the hinge oil cylinder can work; however, since there is no base when the hinge oil cylinder is installed, it is more difficult to install the hinge oil cylinder. Without the support of the base, the position of the oil cylinder needs to be installed and adjusted more accurately; at the same time, without the base, the risk of tilting or accidental movement of the oil cylinder may increase, which may cause the oil cylinder to be unstable during use, or even collapse or slide, causing safety hazards and accidents. In view of this, we introduce a hinge oil cylinder and its base. Summary of the invention
