Small-pipe-diameter rapid connector

Abstract

The invention discloses a small-pipe-diameter rapid connector which comprises a connector pipe and a gland arranged on the connector pipe in a sleeved mode. The gland is detachably connected with the connector pipe through threads, a compressing ring is arranged at the end in the connector pipe, and one end of the compressing ring abuts against a sealing ring arranged in the connector pipe. The small-pipe-diameter rapid connector further comprises an elastic snap ring and an annular snap ring base with the circular-truncated-cone-shaped outer wall, the snap ring base is arranged in the gland, a first opening is formed in the outer wall of the snap ring base, a ring body of the elastic snap ring is inlaid in a body of the snap ring base, claw teeth of the elastic snap ring extend out of the inner surface of the body of the snap ring base, a second opening is formed in the position, corresponding to the first opening, of the elastic snap ring, the gland is tightly screwed and arranged on the connector pipe in a sleeved mode, the snap ring base and elastic snap ring are compressed through the gland in the radial direction to be inwards converged, and a pipe body arranged in the connector pipe is clamped through the claw teeth. The small-pipe-diameter rapid connector has the advantages of being simple in structure, low in production cost, high in stability, firm in fixing, convenient to install and long in service life, saving energy and the like.

Description

technical field [0001] The invention relates to the technical field of quick connectors for pipe bodies, in particular to a small-diameter quick connector suitable for connecting conveying pipelines with small diameters. 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 ...

AI Technical Summary

Problems solved by technology

When the quick pipe joint of this structure is used for a long time, it is easy to damage the pusher, or the strength of the aging structure of the pusher is reduced, so that the pusher cannot apply enough force to press the elastic snap ring to spread the claw teeth, affecting the quick pipe joint The use of the quick pipe joint shortens the service life

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, the fixation is not firm, and the claw teeth will be damaged, and the quick pipe joint of this structure also has complex structure, Problems such as high production cost and inconvenient use
