Abstract
The utility model relates to a pipe joint with fast mounting and dismounting, comprising a joint body at least arranged with a joint pipe, a pipe, a limiting ring on the pipe and a sealed rubber circle. The utility model also comprises a sliding cover, a replacing spring, a steel ball and an elastic retainer. The elastic retainer is arranged at a circular flute of the joint pipe end, and the circle of the joint pipe closely connected the elastic retainer is equally opened with at least three converse taper steel ball holes. The steel balls are arranged in the steel ball holes, and the sliding cover is sleeved on the joint pipe. A composite spring is arranged on the joint pipe between the shaft shoulders at the back of the sliding cover and the joint pipe. An inner protruding ring of the sliding cover is tightly close to the elastic retainer and presses on the steel ball. The steel ball protrudes toward the joining inner pipe portion. After the connection of the joint pipe and the pipe, the limiting ring on the pipe tightly presses the steel ball, and the sealed rubber circle tightly presses the bottom hole shoulder of the joint pipe. Compared with the prior art, the utility model has the advantages of fast and convenient mounting and dismounting without the mounting or dismounting tools, simple structure and low cost, which is applicable for the pipe assembly and usage.
Description
Affiliated technical field
The utility model relates to the pipe joint that connecting tube is used, particularly a kind of quick coupling.
Background technique
In the prior art, the structure of pipe joint commonly used is foolproof, only processes internal thread in each through hole, by being connected with the outside thread of tube end pipe is linked together.This traditional pipe joint cost is very cheap, but construction the time must be wrapped with raw meal belt at the external pipe thread place, again with spanner with in the pipe spinning in pipe joint, so its speed of application is slow, mounting or dismounting are inconvenient.Though prior art is also developed some easily mounting or dismounting pipe joints, because complex structure, used accessory is many, the cost height, and also need instrument such as spanner during construction, speed of application is also unhappy, so it applies not extensive.
Summary of the invention
In order to solve the problem that the conventional pipe joint speed of application is slow and be inconvenient to install and remove, the utility model provides a kind of quick coupling.This quick coupling does not need auxiliary mounting tools such as spanner when construction, can improve the connection and the dismounting speed of pipeline greatly, and simple in structure, low cost, and sealing is reliable.
Above-mentioned task realizes by this way: this quick coupling comprises the fittings body that is provided with a conjugation tube at least, pipe and on limited ring and sealing rubber ring, it also includes flip sleeve, Returnning spring, steel ball and circlip, circlip is located on the annular groove of conjugation tube termination, evenly have the inversed taper platform shape steel ball hole that is not less than three at least on the conjugation tube circumference of circlip being right after, steel ball is placed in the steel ball hole, flip sleeve is placed on the conjugation tube, complex spring is arranged on the conjugation tube between the shaft shoulder of flip sleeve and conjugation tube rear end, the internal projecting ring of flip sleeve is near circlip and be pressed on the steel ball, steel ball part in conjugation tube is protruded, conjugation tube is with after pipe is connected, limited ring on the pipe is near steel ball, and its sealing rubber ring presses on the shoulder of hole, conjugation tube bottom.
The technical program can also be taked following advantageous measure:
The quantity of described inversed taper platform shape steel ball hole is preferably six.
Returnning spring preferably is placed on the conjugation tube between the flip sleeve internal projecting ring and the conjugation tube shaft shoulder.
The hole shoulder of described conjugation tube is the chamfering type, and sealing rubber ring is a triangle.
The utility model is to use like this: in the time of pipe need being connected, earlier with the past pusher of the flip sleeve on the pipe joint, make the compressing of its internal projecting ring disengaging to steel ball, then pipe is inserted and be close to conjugation tube endoporus bottom until sealing rubber ring, loosen flip sleeve subsequently, return under the elastic force effect of Returnning spring, its internal projecting ring is oppressed steel ball again, because the diameter of the miner diameter end of taper type steel ball hole less than steel ball size, makes it partly to protrude in conjugation tube, just in time is stuck in the rear end of limited ring, pipe can't withdraw from, and allow its sealing rubber ring press on the shoulder of the hole of conjugation tube bottom, play good seal action, thereby the pipe at two ends is linked together fast; When needs are dismantled, as long as with the past pusher of the flip sleeve of conjugation tube, make the compressing of its internal projecting ring disengaging to steel ball, pipe is pulled out just can then.The effect of circlip is to prevent that flip sleeve from skidding off outward.
From structure of the present utility model and mounting and dismounting method as seen, it is convenient that compared with the prior art the utility model has fast assembling and disassembling, without any need for handling instrument, and simple in structure, good airproof performance and making easily and advantage such as cost is lower, easy to utilize.
The utility model is fit to two logical, three logical and swan neck joint employings.

Embodiment
See figures.1.and.2, a kind of quick coupling comprise the fittings body 1 that is provided with a conjugation tube 2 at least, pipe 3 and on limited ring 4 and sealing rubber ring 5.
The utility model also comprises flip sleeve 6, Returnning spring 7, steel ball 8 and the circlip 9 that is arranged on the conjugation tube 2.Have a groove 10 that cooperates with circlip 9 in the termination of conjugation tube 2, and evenly have six inverted cone steel ball holes 11 on conjugation tube 2 circumference near groove 10, steel ball 8 is placed in the steel ball hole 11.The size of steel ball hole 11 is suitable with the degree of depth that steel ball 8 can extend about 1/3rd diameters of conjugation tube 2 endoporus.Near the front end place internal projecting ring 12 is set at flip sleeve 6.Flip sleeve 6 is socketed on the external diameter of conjugation tube 2, Returnning spring 7 is socketed on the conjugation tube 2 between the shaft shoulder of flip sleeve 6 internal projecting rings 12 and conjugation tube 2 rear ends, on groove 10, load onto circlip 9, the internal projecting ring 12 of flip sleeve 6 is just near circlip 9, and be pressed on the steel ball 8, steel ball 8 is projecting inward to conjugation tube 2.Pipe 3 is with after the conjugation tube 2 of fittings body 1 engages, and the limited ring 4 on the pipe 3 is that the sealing rubber ring 5 of right-angled triangle presses on the hole of conjugation tube chamfering shape shoulder 15 near steel ball 8 and with the cross section.
For improving the serviceability sealing of sealing rubber ring 5, can adopt silicone rubber to make.
