Abstract
A minor-caliber rapid connection pipeline joint comprises a joint pipe and glands, wherein the two ends of the joint pipe are sleeved with the glands. The glands and the joint pipe are detachably connected through threads. A snap ring base is arranged on each end of the joint pipe. One end of each snap ring base extends into the joint pipe and abuts against a sealing ring arranged in the joint pipe. The other end of each snap ring base is provided with an elastic snap ring. Each elastic snap ring comprises a ring body and claw teeth. A boss is arranged inside each gland and close to the end of the joint pipe. Each boss is provided with an annular protrusion protruding in the direction of the corresponding claw teeth. Grooves are formed by the inner walls of the glands, the bosses and the annular protrusions. The ring bodies are arranged in the grooves and the annular protrusions abut against the inner rings of the ring bodies. The minor-caliber rapid connection pipeline joint has the advantages of being simple in structure, low in production cost, high in stability, firm in fixation, convenient to install, capable of saving energy and the like.
