Abstract

This invention relates to a fluid quick joint including multiple quick male and female joints, socket and bolt pieces, the joints contain hollow bodies, sealing cores, back top bolts and fastened spring between the sealing core and the back to bolt, the male joint is fixed in a through hole of the socket piece, the female is fixed in a through cave on the bolt which front part can be plug into the front of the socket and locked before connection the sealing cores of the front quick connecting male and female joints are packet with the inside wall of the body to stop the quick joints, after connection, sealing cores are conflict with each other to leave the packing position to conduct the quick connectors.

Description

technical field [0001] The invention relates to a fluid transmission pipe fitting, in particular to a quick joint of a pipeline. Background technique [0002] At present, in the application of hydraulic fluid, the quick connection between various pipelines is limited to the quick connection of a single pipeline, and there is no device for realizing the quick connection between multiple pipelines at the same time. A Chinese patent with the authorized notification number CN2163924Y discloses a quick connector device for pressure pipes. Before the connection, the pressure pipes are all in a cut-off state. After the pressure pipe is inserted into the compression valve and moves, the two pressure pipes are connected , and rely on the tight bite of the inner ring teeth of the snap ring to maintain the compressed state. For disassembly, a pressure release sleeve is required. [0003] This kind of quick connector for a single pipeline requires a certain amount of operating space d...
