Abstract

The utility model relates to a pipe joint. The pipe joint comprises a hollow transparent pipe body and pipe sleeves coaxially inserted into the two ends of the transparent plastic pipe body, wherein an annular shoulder which is indent in the radial direction is formed in the middle of the transparent plastic pipe body; sealing rings are arranged at the two ends of the annular shoulder in the axial direction; baffle rings are pressed against the sealing rings; clamp spring claws are arranged at the two ends of the baffle rings in the axial direction; the clamp ring claws have outer edges extending outwards along the radial direction; the end faces of one sides, which are close to the annular shoulder, of the outer edges are pressed against the outer end faces of the baffle rings; clamp spring sleeves are pressed against the end faces of one sides, which are far away from the annular shoulder, of the outer edges; flanges are formed on the inner circumferential surfaces of the clamp spring sleeves by extending inwards in the radial direction; indent annular grooves are formed in the outer circumferential surfaces of the pipe sleeves; the clamp spring sleeves are clamped in the annular grooves of the pipe sleeves through the flanges, and are fitted in a sliding way within an axial distance defined by the annular grooves. The pipe joint is simple in structure and novel in design.

Description

A kind of pipe joint

Technical field

The utility model relates to a kind of pipe joint connecting for Fiber Duct, and the pipeline that this pipe joint is also applicable in pneumatic or hydraulic fluid system simultaneously connects.

Background technique

Because pipe joint is generally applied in the connection of Fiber Duct or is pneumaticly connected with the pipeline of the fluid motions such as hydraulic pressure, therefore, no matter pipe joint is in engineering or on civilian, use all very general, the most common pipe joint is generally metallic article and locks the connection of nut formation pipeline in the market, this kind of pipe joint manufacture cost is high, and the easy oxidation and rusting of metallic article, affects working life.

Summary of the invention

The purpose of this utility model is to overcome the defect of prior art, provides a kind of simple in structure, novel in design and can effectively improve the pipe joint in working life.

For achieving the above object, the utility model adopts a kind of pipe joint, comprise that the transparent plastic body of hollow and concentric are inserted into the pipe box at described transparent plastic body two ends, the wall thickness of wherein said transparent plastic body is even, and the neutral position of this transparent plastic body has the annular convex shoulder radially concaving into, two ends on this annular convex shoulder is axial are provided with seal ring, on described seal ring, butt has baffle ring, the endoporus of this baffle ring is taper hole shape and cone angle towards annular convex shoulder one side, in the axial direction of this baffle ring, two ends are provided with jump ring pawl, this jump ring pawl has centered by longitudinal center line and the claw of array distribution and connect the outward edge extending radially outwardly of described claw, described outer peripheral near the end face of annular convex shoulder one side and the exterior edge face of described baffle ring formation butt, described outer peripheral remote on the end face of annular convex shoulder one side butt be provided with jump ring cover, on the inner peripheral surface of this jump ring cover, extend radially inwardly and be provided with flange, on the outer peripheral surface of described pipe box, offer the annular groove of indent, described jump ring cover is installed on by flange in the annular groove of described pipe box and and then forms the slip that jump ring is enclosed within the axial distance that annular groove limits and coordinate.

After technique scheme improvements over the prior art, reach following beneficial effect: 1, because the wall thickness of transparent plastic body is even, especially circularize the position of convex shoulder in inner concave shape, wall thickness can effectively reduce the internal stress at convex shoulder place uniformly, with respect to the pipe joint on existing market at the wall thickness of this position large and stress concentration and and then the situation that easily cracks, improve greatly the working life of pipe joint in the utility model, and outward appearance novelty; 2, owing to adopting plastics body and pipe box, with respect to the metallic article of extensive use in prior art, effectively reduce cost of production, and transparent plastic body has the characteristics such as anti-oxidant, with respect to the metallic article being in use easily oxidized, more ensure the sealing of pipe joint, and improved working life; 2, owing to having adopted jump ring pawl in pipe joint inside, and this jump ring pawl has claw, and in the time that pipe box plug-in mounting enters transparent plastic body, this pipe box apical grafting claw, impels claw to exert pressure to baffle ring and seal ring, therefore, strong guarantee the sealability of pipe joint.
