Description

Technical Field

[0001] The utility model relates to the technical field of joints, in particular to a sealed and leak-proof hydraulic joint. Background Art

[0002] Hydraulic fittings are essential components in hydraulic systems, connecting various hydraulic components to form a closed circuit. They are widely used in various pumps, valves, cylinders, and hydraulic motor drives, providing connections, sealing, and vibration reduction. Hydraulic fittings generally have two primary functions: retention and sealing. They help contain the hydraulic fluid, preventing it from escaping the system, and help direct flow and maintain system pressure.

[0003] For example, Chinese patent publication number CN221196501U proposes a sealed and leak-proof hydraulic joint, which includes a joint body, a connecting pipe provided on one side of the joint body, a connecting groove formed on one side of the joint body, an external sleeve fixedly connected to one side of the surface of the connecting pipe, one side of the connecting pipe extending into the interior of the connecting groove and engaging with the connecting groove, and an annular plate fixedly connected to the interior of the joint body corresponding to the outer side of the connecting pipe. This sealed and leak-proof hydraulic joint provides significant benefits through the unique design of the annular plate, roller, anti-slip pad, external sleeve, support ring, movable ring plate, limit ring plate, connecting sleeve and anti-slip ribs. These design elements together optimize the installation process of the joint, allowing the connecting pipe to be quickly and easily installed on the joint body. This convenient installation method greatly improves work efficiency, reduces installation time and reduces installation difficulty. However, in actual use, if the sealing structure of this solution is used for a long time, it is very easy to leak, thereby affecting the working efficiency of the hydraulic component. To solve the above problem, we propose a sealed and leak-proof hydraulic joint. Utility Model Content
