Abstract
The utility model discloses a joint of difficult infiltration, including connecting main part, link, it all has the link to connect the main part both sides, it all has the through -hole to connect main part center and link center, there is the external screw thread that is higher than link smooth surface on the link, has first annular groove between the external screw thread region of link and the tip of link, have first seal ring in the first annular groove, the external screw thread of link regional with the joint main part between have the second annular groove, have the second seal ring in the second annular groove. The utility model discloses a set up the both sides at the external screw thread with first seal ring and second seal ring for the joint can have fine leakproofness, prevents the infiltration of installation back, connecting the main part and being hexagonal prism shape, the through -hole in the link is hexagonal prism shape and has made things convenient for installing in the dismantlement of connecting.
Description
[technical field]
This utility model relates to the technical field of the technical field of tubing, particularly joint.
[background technology]
Joint is the conventional accessory coupled together by two water pipes, and existing joint in use sealing is not ideal enough, is installing and is easily seeping water in use procedure, will be installed to bit comparison trouble, be also easy to waste water resource.General joint easily snaps off when dismantling after using the time longer, and the part in water pipe that fractures is not easy to take out.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, it is proposed to a kind of joint not easily seeped water, it is possible to make joint not easily seep water, and readily accessible.
For achieving the above object, the utility model proposes a kind of joint not easily seeped water, including adapter body, link, all there is link described adapter body both sides, all there is through hole at described adapter body center and link center, described link has the external screw thread higher than link smooth surface, first annular groove is had between external screw thread region and the end of link of link, the first seal ring is had in first annular groove, there is the second annular groove between external screw thread region and the adapter body of described link, in the second annular groove, have the second seal ring.
As preferably, described adapter body is hexagon, and the through hole in link is hexagon, and the first seal ring external diameter is less than major diameter of external thread.
As preferably, described second seal ring is made up of the first concentric ring body and the second ring body, and the first ring body is in the close external screw thread side of the second seal ring, and the external diameter of the first ring body is less than major diameter of external thread, and the external diameter of the second ring body is more than major diameter of external thread.
The beneficial effects of the utility model: this utility model is by being arranged on externally threaded both sides by the first seal ring and the second seal ring so that joint can have fine sealing, it is prevented that seep water after installation；Second seal ring is formed so that the end of joint and water pipe junction is well sealed, can be prevented oozing out of water further by different the first ring body of external diameter and the second ring body；Adapter body is hexagon, the through hole in link be hexagon facilitate joint be installed on dismounting.
Feature of the present utility model and advantage will be described in detail in conjunction with accompanying drawing by embodiment.
[accompanying drawing explanation]
Fig. 1 is the front view of a kind of joint not easily seeped water of this utility model；
Fig. 2 is the left view of a kind of joint not easily seeped water of this utility model.
In figure: 1-adapter body, 2-link, 10-through hole, 20-external screw thread, the first annular groove of 21-, 22-the second annular groove, 23-the first seal ring, 24-the second seal ring, 26-the first ring body, 27-the second ring body.
[detailed description of the invention]
Consult Fig. 1 and Fig. 2, a kind of joint not easily seeped water of this utility model, including adapter body 1, link 2, all there is link 2 described adapter body 1 both sides, all there is through hole 10 at described adapter body 1 center and link 2 center, described link 2 has the external screw thread 20 higher than link 2 smooth surface, first annular groove 21 is had between external screw thread 20 region and the end of link 2 of link 2, the first seal ring 23 is had in first annular groove 21, the second annular groove 22 is had between external screw thread 20 region and the adapter body 1 of described link 2, the second seal ring 24 is had in second annular groove 22, described adapter body 1 is in hexagon, through hole 10 in link 2 is in hexagon, first seal ring 23 external diameter is less than external screw thread 20 external diameter, described second seal ring 24 is made up of the first concentric ring body 26 and the second ring body 27, first ring body 26 is in close external screw thread 20 side of the second seal ring 24, the external diameter of the first ring body 26 is less than external screw thread 20 external diameter, the external diameter of the second ring body 27 is more than external screw thread 20 external diameter.
Utility model works process:
A kind of joint not easily seeped water of this utility model is in the course of the work, when after the connecting water pipe of joint two ends, first seal ring 23 water-swellable, making there is good sealing between joint and water pipe, if still having part water along oozing out, then these water make the second seal ring 24 expand when encountering the second seal ring 24, the end of water pipe is well sealed, under the double shield of the first seal ring 23 and the second seal ring 24, joint has good sealing, it is prevented that infiltration.Adapter body 1 makes joint be easily installed in hexagon and dismantles, and through hole 10 is in hexagon so that joint also can facilitate to pull down from water pipe after unexpected fractureing.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after this utility model simple transformation is belonged to protection domain of the present utility model.
