Background technique
At present, plastic water pipe of the prior art connects with hot melt or gluing mode usually, and this Placement can only be destroyed joint in case formation can't be changed as just changing, and can't reuse.Chinese patent notification number CN201723888U discloses a kind of universal joint; It comprises nut, screwed pipe, the pipe of press-offing, metal back-off ring, packing ring and O-ring seal, and nut is provided with through hole, and the diameter of the Guan Yiduan that press-offs is less than through-hole diameter; The pipe the other end of press-offing is provided with snap ring; The snap ring diameter is greater than through-hole diameter, and screwed pipe is provided with first screw thread, and the nut set inside has second screw thread that is complementary with first screw thread; Press-off pipe, metal back-off ring, packing ring and O-ring seal is superimposed in turn and fixed in nut and the screwed pipe cavity through first screw thread and second screw thread, and metal back-off ring is provided with a plurality of fins with locking back-off near the packing ring side.This universal joint is easy to operate, can reuse.But because first screw thread that is provided with is an outside thread on the screwed pipe, second screw thread that is complementary with first screw thread of nut set inside is an internal thread; The diameter of nut need be provided with greatlyyer like this, and the diameter that therefore can cause joint is excessive and can not be applicable to the occasion that some are higher to volume requirement, for example; When water pipe need be imbedded within the walls; As adopt existing pipe joint, just need on metope, open darker groove, inconvenient operation.
Therefore, provide a kind of volume less, going for some quick couplings to the higher occasion of volume requirement becomes the industry technical issues that need to address.
The model utility content
The utility model technical issues that need to address are to provide a kind of volume less, go for some quick couplings to the higher occasion of volume requirement.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: quick coupling comprises body; The end of body is provided with the swivel nut that is spirally connected, and body end inwall is provided with ring-shaped step, is placed with seal ring and packing ring on the ring-shaped step successively; Be provided with the tube of press-offing in the swivel nut, the external diameter of the described tube of press-offing is greater than the internal diameter of swivel nut, and the tube of press-offing is provided with at least one axial retraction slot; Week is provided with annular groove in the described swivel nut, the outer wall of the tube of press-offing is provided with the convexity that may be stuck in the annular groove, the tube of press-offing be provided with the back-off metal fin interior week; The end of described body is provided with internal thread, and described swivel nut is provided with the outside thread that matches with internal thread.
Described press-off the tube and the back-off metal fin be the injection moulding all-in-one-piece.
Distance between the inner end face of described ring-shaped step and swivel nut is less than or equal to the thickness sum of seal ring and packing ring.
Described packing ring is provided with and the inner inclined-plane that matches of the tube of press-offing.
The sidewall of described body is provided with transparent window, establishes in the transparent window and uses transparent picture.
Owing to adopted above-mentioned structure; The end of the body of the utility model is provided with internal thread; Described swivel nut is provided with the outside thread that matches with internal thread, and the diameter of swivel nut is less than the diameter of body, and the diameter of swivel nut need not to be provided with bigger; The diameter of joint is little, goes for some occasions higher to volume requirement.
Description of drawings
Fig. 1 is the phantom of quick coupling.
Fig. 2 is the sectional view that the utility model is used for valve.
Embodiment
Be described in further detail below in conjunction with the embodiment of accompanying drawing the utility model.
As shown in Figure 1, the described quick coupling of the utility model, this embodiment is used to connect straight two of water pipe lead to; It comprises body 1; The end at the two ends of body 1 is respectively equipped with the swivel nut 2 that is spirally connected, and the end of described body 1 is provided with internal thread, and described swivel nut 2 is provided with the outside thread that matches with internal thread; The diameter of swivel nut is less than the diameter of body like this, and the diameter of swivel nut need not to be provided with bigger.Body 1 end inwall is provided with ring-shaped step 3, is placed with seal ring 4 and packing ring 5 on the ring-shaped step 3 successively.Distance between described ring-shaped step 3 and the swivel nut 2 inner end faces is slightly less than or equals the thickness sum of seal ring 4 and packing ring 5, and seal ring 4 and packing ring 5 are pressed between ring-shaped step and the swivel nut through swivel nut and the body that is spirally connected.Be provided with the tube 11 of press-offing in the swivel nut 2, the outer end of the tube 11 of press-offing is provided with an annular edge, and described external diameter of press-offing tube 11 is slightly larger than the internal diameter of swivel nut 2, and the internal diameter of the tube 11 of press-offing and the internal diameter of body 1 are about equally.The described tube 11 of press-offing stretches into an end end face in the swivel nut 2 and is provided with at least one axial retraction slot 6, and through the contraction of retraction slot 6, tube 11 diameters of press-offing can diminish, and the tube 11 of press-offing like this is able to be inserted in the swivel nut 2.Be provided with annular groove 9 week in the described swivel nut 2, the outer wall of the tube 11 of press-offing is provided with the convexity 7 that may be stuck in the annular groove 9.That press-offs tube 11 is provided with back-off metal fin 8 interior week, and the described tube 11 of press-offing is injection moulding all-in-one-pieces with back-off metal fin 8.Described packing ring 5 is provided with and the inclined-plane 10 that matches, tube 11 ends of press-offing, and pushes the tube 11 o'clock of press-offing, and tube 11 ends of press-offing can be opened under the effect on inclined-plane 10.The sidewall of described body is provided with transparent window 12, transparent window 12 be positioned at body lean on ring-shaped step with inner segment on, establish in the transparent window 12 with transparent picture 13, can see the degree of depth of water pipe insertion through transparent picture 13, can guarantee that water pipe is inserted into the position.
When the utility model connected water pipe, water pipe was inserted in the body 1 through the tube 11 of press-offing, and seal ring 4 and packing ring 5 are pressed between ring-shaped step and the swivel nut through swivel nut and the body that is spirally connected; Seal ring 4 plays seal action; The water pipe that inserts in the tube 11 of press-offing makes tube 11 distendings of press-offing, and the convexity 7 of tube 11 outer walls of press-offing is stuck in the annular groove 9, and the tube 11 of press-offing can not deviate from from swivel nut 2; Back-off metal fin 8 tips upside down on the outer wall of water pipe, and anti-water stopping tube gets loose from swivel nut and body.
When water pipe and the utility model are taken apart, inwardly push the tube 11 of press-offing, open under the effect on inclined-plane 10 tube 11 ends of press-offing, and back-off metal fin 8 no longer tips upside down on the outer wall of water pipe, and water pipe can loose from swivel nut and body.
As shown in Figure 2, the utility model can be used on the valve, also can be used for curved two logical or threeways, can also be used for the link that other are used to connect water pipe.
In a word; The above-mentioned preferred implementation though the utility model has been given an example; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of the utility model only if such variation and remodeling have departed from the scope of the utility model.
