Problems solved by technology

The quick pipe joint of this structure has a complex structure, which increases the production cost and is inconvenient to use
Moreover, when the pusher presses the elastic snap ring from the axial direction, the elastic snap ring is prone to displacement, the stability is not high, and the fixation is not firm.

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.

Description

technical field [0001] The invention relates to the technical field of quick joints of pipe bodies, in particular to a small-diameter quick-connection pipe joint suitable for small-diameter conveying pipes. Background technique [0002] Chinese patent document CN101328997A discloses a quick pipe joint for compressed air pipes, including a joint pipe and a gland. The inner end of the inner end extends into the inside of the joint pipe, and a sealing ring is provided against the snap ring seat. The inner ring of the sealing ring protrudes from the inner diameter of the snap ring seat; the outer end surface of the snap ring seat is provided with a metal elastic snap ring. The snap ring includes a ring body and claw teeth. The claw teeth are flanged toward the snap ring seat, and a bevel ring is provided at the opening of the snap ring seat. The claw teeth are set on the bevel ring; the outer end of the elastic snap ring is provided with a pusher, The two ends of the piece are ...
