Abstract

The invention provides a connecting structure of a quick coupling, and belongs to the technical field of pipeline connection. The quick coupling solves the problem that when current quick coupling is assembled, parts are needed to be installed into the quick coupling one by one so that the quick coupling is inconvenient to assemble, and parts are easy to be assembled in malpositions to lead to poor sealing effect. The quick coupling comprises a body provided with a connecting channel and a locking assembly provided with a right half ring. A locking assembly is arranged at an opening of at least one connecting channel. The connecting channel is internally provided with tubular inner shells in one-to-one correspondence with the locking assemblies and a sealing ring assembly through which the inner shell and the outside face of an adaptor are sealed. The outer end of the inner shell is connected with the right half ring through a buckling structure which enables the right half ring and the inner shell be buckled to form a compactly matched whole and positions the sealing ring assembly. The whole is fixedly connected with the body. The buckling assembly, the inner shell, the sealing assembly and the buckling structure in the body are buckled so that the quick coupling can be assembled at one time and is convenient and rapid to install.

Description

A kind of rapid pipe joint
Technical field
The invention belongs to technical field of pipeline connection, relate to a kind of rapid pipe joint.
Background technique
The application of rapid pipe joint makes pipeline connection technology more ripe, especially directly-inserted quick quick coupling, is used widely in daily life and the equipment of industrial product.Directly-inserted quick quick coupling is compared and is adopted heat melting device to connect, join strength is high, shock resistance is good, and fasten disposable for connection part, overpressure is larger, make bore expand counter make it detain tighter, avoid the possibility loosening and leak, and without the need to hot melt, avoid Site Welding job execution painstaking, quick for installation, save time power saving saving of labor.
As a kind of Chinese patent [application number: 200820086195.6, notification number: CN201187650] of fast joint structure of pipe.It comprises the body with attachment hole, can with the adapter phase clamping of inserting in attachment hole, a collar is provided with in attachment hole, this collar is fixed in attachment hole by positioning means, collar has several claws tilted inside attachment hole, being provided with an annular socket that claw can be strutted when it being pressed inside attachment hole in the outside of collar, being provided with the O RunddichtringO be fixed in attachment hole in the inner side of collar.When it adopts adapter to insert attachment hole, adapter can be blocked by claw on collar 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 by intrinsic inner body all marshallings fixing, body outside last injection moulding again, but the annexation that each component of inside are unstable, nor easily fix successively, make troubles to assembling, and when injection moulding body easy dystopy, affect sealability, even cause product failure.
For solving the problem, people devise 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, in attachment hole, there is step, barrel-type casing and a retainer ring be fixed between barrel-type casing and step is also fixed with in attachment hole, between barrel-type casing and retainer ring, clamping has a collar, collar has several towards the claw inside attachment hole, an intubate that claw can be strutted when it being pressed inside attachment hole is provided with outside collar, being provided with cross section between the step of attachment hole and retainer ring is pancake seal ring, inside retainer ring, there is annular groove, annular groove internal fixtion has O RunddichtringO.The inner body of this rapid pipe joint fastens all mutually, be embedded with O RunddichtringO inside retainer ring, fasten with seal ring again outside retainer ring, connect more firm between each part in the inside assembled like this two, be not easy dystopy when the body of injection moulding outer ring or fall apart, bringing convenience to assembling.
But, this Quick joint for pipeline directly contacts with the body of outer ring due to its seal ring, and the general application of rubber material of seal ring is made, yielding under high temperature or high pressure, make easily to cause damage to seal ring when injection moulding body, cause overall sealing performance to fall flat; And barrel-type casing and the unstable connection of retainer ring, be also easier to dystopy when assembling.
Summary of the invention
