A kind of quickly jointed tubular workpieces with check device
Technical field
The utility model belongs to quickly jointed tubular workpieces technical field more particularly to a kind of quickly jointed tubular workpieces with check device.
Background technique
In recent years, all kinds of model water purifiers start to come into the masses of the people family, or are used for various office spaces, wherein table top
Formula type due to installing, using all easily, it is deep by many user preferences.Existing water purifier is since Inlet and outlet water port using connecing fastly
There is unsatisfactory place in pipe fitting, a kind of plugging quick pipe connecting part as disclosed in patent 201210269272.2 and takes pipe sleeve cylinder,
Push-in type quick pipe connecting piece disclosed in patent 201020050095.5 etc., there is deficiency in use in quickly jointed tubular workpieces :-
Denier closes water source, and after extracting water-supply-pipe, Yu Shuihui is flowed outwardly from quickly jointed tubular workpieces, more than being detained in filter core in water purifier cabinet
Water will cause unnecessary loss and surrounding enviroment pollution in this way;In addition, this quickly jointed tubular workpieces port is clearly after extracting water-supply-pipe
It freely opens or smooth, extraneous bacterium, dust, small worm etc. can enter port, cause adverse effect, such as have water purifier using fast
Jointed tubular workpieces are Inlet and outlet water port, just will appear such reason and cause inside water purifier " smelly water ".
The technical solution that problems have practical significance is solved at present, is had as disclosed in patent 201420266410.6
The inside and outside spiral shell quick connector of check device, a kind of pipe connector with check function disclosed in patent 201120428135.x
Deng, but these patented technologies all utilize the check device of check valve on similar pipeline, there are still deficiencies: only can solve extraction water
There is nonreturn valve core of retrodicting strong compared with superfluous water ability while pipe and play blocking action, prevents remaining water outflow;If extracting conduit
While again without remaining water or seldom remaining water when, valve rod or plug are difficult to reset, this quickly jointed tubular workpieces port is obviously still freely to open
Or it is smooth, extraneous bacterium, dust, small worm etc. still can enter port, cause adverse consequences.
Utility model content
Enter quickly jointed tubular workpieces to solve leaked water and extraneous dirt after quickly jointed tubular workpieces water pipe of the existing technology is extracted
Problem is not changing on infusion pipeline under precondition of the selection using quickly jointed tubular workpieces, and the utility model provides a kind of with only
The water stop portion that can be automatically closed is arranged in the quickly jointed tubular workpieces of return device, effectively prevent residual liquid inside complete machine from fast
Jointed tubular workpieces outflow or bacterium, dust, the small worm in the external world etc. enter quickly jointed tubular workpieces.
It is a kind of with check device in order to solve the above technical problems, technical solution used by the utility model is as follows

Specific embodiment
Embodiment
As shown in Figures 1 to 3, a kind of quickly jointed tubular workpieces with check device, including pipe fitting ontology 1, on the pipe fitting ontology 1
Through there is connecting cavity 11, water stop portion, sealing ring 6 and tight lock part are disposed in the connecting cavity 11, the water stop portion includes
Bracket 2 and obturating plug 5, the obturating plug 5 are fixed in connecting cavity 11, and running through on the obturating plug 5 has limbers 51, the bracket
2 slide through limbers 51, and the both ends of the bracket 2 are fixedly installed chock plug 4 and elastic element, and the chock plug 4 and elasticity
Element is located at the two sides of obturating plug 5, is extended with limit plate 21 on the bracket 2 between obturating plug 5 and elastic element, described
Chock plug 4 is for blocking limbers 51, and the tight lock part is for locking water pipe 7, and the elastic element is close to tight lock part, and the bullet
Property element and 7 inner wall of water pipe cooperate.For the ease of elastic element be inserted into water pipe 7, the elastic element to far from bracket 2 direction
First expand after-contraction.Elastic element described in the present embodiment selects circlip 3.When water pipe 7 wait connect is inserted to connecting cavity 11, circlip 3
It is inserted into water pipe 7, circlip 3 resists 7 inner wall of water pipe and is in along 7 radial outward dilations trend of water pipe, and the end of water pipe 7 at this time
It is contacted with limit plate edge 21.
For the ease of chock plug 4 be inserted into limbers 51, the chock plug 4 towards bracket 2 direction shrink, the limbers 51 in
Chock plug 4 cooperates.In order to reach preferable sealing effect, the material selection silica gel of the chock plug 4.It is offered in the connecting cavity 11
First annular groove, the obturating plug 5 are arranged in the first annular groove, the material selection rubber of the obturating plug 5, the obturating plug 5 and the first ring
Slot interference fit.The sealing ring 6 is between connecting cavity 11 and water pipe 7;The second annular groove, institute are offered in the connecting cavity 11
Sealing ring 6 is stated to be arranged in the second annular groove.
The tight lock part includes the toroidal frame 81, calvus 82 and retainer plate 83 for successively crimping setting, and the toroidal frame 81 supports
It leans against on sealing ring 6, sliding is provided with buckle 84 in the retainer plate 83, and the is extended on the outer circumference surface of the retainer plate 83
One protrusion 831 is extended with the second protrusion 832 on the inner wall of the retainer plate 83, offered in the connecting cavity 11 with it is first convex
The card slot of 831 cooperations is played, the limiting slot 841 with 832 cooperation of the second protrusion is offered on the buckle 84, when 84 courts of the buckle
Calvus 82 is strutted when sliding to calvus 82, in order to guarantee that claw blocks water pipe 7, the calvus 82 is set as 10 pawls.Tight lock part
Structure sees the acting pipe locking device disclosed in patent document 201020050095.5, and tight lock part has easy to connect, stable
And the advantages of good airproof performance.
Working principle is as follows:
When connecting 7 normal water flowing of water pipe on pipe fitting ontology 1, the end of water pipe 7 resists limit plate 21, and circlip 3 resists water pipe 7
Inner wall is simultaneously in along 7 radial dilatation trend of water pipe, and chock plug 4 is detached from limbers 51, and the water in pipeline circulates through limbers 51;
When needing to change or removing water pipe 7, as shown in Figure 1, being first pressed into buckle 84 to 82 direction of calvus, 84 ends are buckled
Portion opens calvus 82, so that water pipe 7 is detached from the constraint of calvus 82 first, so that water pipe 7 is extracted from inside to outside from connecting cavity 11, and because of card
Spring 3 is in along 7 radial outward dilations trend of water pipe and resists 7 inner wall of water pipe, so that water pipe 7 be allowed successively to drive circlip 3, bracket 2
It is moved out with chock plug 4, when chock plug 4 is inserted into limbers 51 and blocks limbers 51, effectively prevent leaked water, while water pipe 7
After being detached from circlip 3, water pipe 7 is pulled out;
As shown in Fig. 2, to be replaced or installation water pipe 7 is inserted into connecting cavity 11 again, one end because of circlip 3 far from bracket 2
Stretching has guiding role with contracting, guarantees that circlip 3 is inserted into water pipe 7, and circlip 3 resists 7 inner wall of water pipe and again in along 7 diameter of water pipe
It is that next more water-changing tube 7 is prepared, while 7 end of water pipe is contacted with limit plate 21 to expansion trend, water pipe 7 pushes 2 He of bracket
Chock plug 4 is moved far from obturating plug 5, and after water pipe 7 is inserted into connecting cavity 11 in place, chock plug 4 is detached from limbers 51, and the water in pipeline starts
It circulates through limbers 51.
