[0002] Mining quick connectors, also known as mining pipe clamps or mining clamps, are metal connectors specifically used to connect mining hose assemblies or other hydraulic parts. Their main function is to conduct or block working fluids. The design of this connector takes into account the harsh environment of coal mines and the need to frequently change working surfaces, making it easy to disassemble and install. In order to increase the corrosion resistance and wear resistance of the connector, the mining quick connector also uses a hexavalent chromium-free zinc plating process.

[0003] The publication number in the prior art is CN216479501U. The mining rotary joint includes an articulated core with a countersunk hole, a rotating base is sleeved on the lower part of the articulated core, a first ring groove, a second ring groove and a third ring groove are arranged on the outer wall of the lower part of the articulated core, a first through hole is arranged on the lower part of the articulated core, the first through hole connects the countersunk hole and the first ring groove, an O-type sealing ring is arranged in the second ring groove, a shaft retaining spring is arranged in the third ring groove, the rotating base is connected to the articulated body, a second through hole is arranged in the articulated body, and the first ring groove is connected to the second through hole. The upper end of the rotating base is pressed against the upper outer edge of the articulated core, and the lower end of the rotating base is pressed against the shaft retaining spring, and the sealing performance between the articulated core and the rotating base is further improved by the O-type sealing ring. The articulated body is arranged on the outer wall of the rotating base, and the liquid in the articulated core flows to the inside of the articulated body along the first through hole, the first ring groove and the third through hole, so that the articulated body can rotate freely along the articulated core, meeting the actual working requirements.

[0004] Although the device has many beneficial effects, the following problems still exist: although the mining joint can realize the free rotation of the hinged body along the hinged core and meet the actual work needs, the mining joint is troublesome to connect during use and cannot be quickly connected, thereby reducing the installation and connection efficiency of the mining joint.
