Description
Technical field
The utility model belongs to the pipeline connection technology field, relates to a kind of rapid pipe joint.
Background technique
The application of rapid pipe joint is so that pipeline connection technology is more ripe, and especially the directly-inserted quick quick coupling is used widely in daily life and the equipment of industrial product.The directly-inserted quick quick coupling is compared and is adopted heat melting device to connect, join strength is high, shock resistance is good, fastens connection part is disposable, and overpressure is larger, bore is expanded instead makes it detain tightlyer, avoid possibility loosening and that leak, and need not hot melt, avoided the Site Welding job execution painstaking, quick for installation, the power saving saving of labor saves time.
Such as a kind of Chinese patent of fast joint structure of pipe [application number: 200820086195.6, notification number: CN201187650].It comprises the body with attachment hole, can with the adapter phase clamping of inserting in the attachment hole, in attachment hole, be provided with a collar, this collar is fixed in the attachment hole by positioning means, collar has several towards the claw of the inboard inclination of attachment hole, be provided with an annular socket that when it is pressed to the attachment hole inboard, claw can be strutted in the outside of collar, be provided with the O RunddichtringO that is fixed in the attachment hole in the inboard of collar.It adopts and takes over when inserting attachment hole, and the claw on the collar can block adapter easily, realizes connecting fast.The advantages such as the fast joint structure connection of this pipe is reliable, flexible and convenient to use, good airproof performance.It is with intrinsic inner body marshalling and fixing all, the body of last again injection moulding outside, but each inner component do not have stable annexation, nor fixing successively easily, make troubles to assembling, and when the injection moulding body easy dystopy, affect sealability, even cause product failure.
For addressing the above problem, people have designed a kind of patent [application number: 201120160406.8, notification number: CN202100866U] of Quick joint for pipeline.This Quick joint for pipeline comprises the body with attachment hole, has step in the attachment hole, also be fixed with barrel-type casing and a retainer ring that is fixed between barrel-type casing and the step in the attachment hole, clamp between barrel-type casing and the retainer ring collar is arranged, collar has several towards the claw of attachment hole inboard, be provided with an intubate that when it is pressed to the attachment hole inboard, claw can be strutted in the collar outside, be provided with cross section between the step of attachment hole and the retainer ring and be pancake seal ring, the retainer ring inboard has annular groove, is fixed with the O RunddichtringO in the annular groove.The inner body of this rapid pipe joint all fastens mutually, the retainer ring inboard is embedded with the O RunddichtringO, and the retainer ring outside fastens with seal ring again, connects more firm between each part two of the inside that assembles like this, when the body of injection moulding outer ring, be not easy dystopy or fall apart, bring convenience to assembling.
But, this Quick joint for pipeline directly contacts with the body of outer ring owing to its seal ring, and the general application of rubber material of seal ring is made, and is yielding under high temperature or high pressure, so that when the injection moulding body, easily seal ring is caused damage, cause overall sealing performance to fall flat; And barrel-type casing do not have stable being connected with retainer ring, is easier to dystopy when assembling yet.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of good sealing effect, rapid pipe joint easy to assembly.
The purpose of this utility model can realize by following technical proposal: a kind of rapid pipe joint, comprise the body with connecting passage and the clip assembly with right half-turn, at least one described connecting passage oral area is provided with a clip assembly, also be provided with in the described connecting passage with clip assembly correspondingly in a tubular form inner housing and can make inner housing and the seal ring assembly of taking over outer side surface and form sealing; Between the outer end of described inner housing and the right half-turn by making right half-turn and the clamping of inner housing phase form a close-fitting integral body and the fastening structure that above-mentioned seal ring assembly is located can being connected; Above-mentioned integral body is fixedly connected with body.
