Abstract
The utility model discloses a fast installing pipe joint. The utility model is characterized in that inner threads and a lug boss are arranged in a pipe body of the joint; an inner sleeve and a thread post sleeve are arranged in the pipe body of the joint too; outer threads of the thread post sleeve are connected with the inner threads in the pipe body of the joint, and the inner sleeve and an inner hole of the thread post sleeve are both cone holes; pipe connecting sleeves are arranged in the cone holes of the inner sleeve and the pipe body of the joint; the outer surfaces of the pipe connecting sleeves are taper surfaces, the middle of the taper holes is big, and both ends of the taper holes are small; the taper surfaces has the same taper as the inner cone holes of the inner sleeve and the thread post sleeve. The utility model has the advantages that the manufacture of threads on connected pipelines is not needed during use; a rubber sealing ring or a rubber sealing gasket does need to be used.
Description
The utility model relates to a kind of pipe joint.
At present, existing pipe coupling generally all is to produce the screw thread identical with pipe coupling on connected pipeline, pipeline could be connected with pipe coupling then, because this pipe coupling need be produced screw thread in use on connected pipeline, therefore exist constructional difficulties, time-consuming taking a lot of work, use very inconvenient shortcoming, for addressing this problem, many fast holding pipe joint technological schemes that do not need to make screw thread on pipeline had once been proposed in the prior art, but in these schemes, generally the pipe connector sleeves of connecting tube is made into symmetrical halves, and seal with rubber ring or rubber pad, this structure is not only cumbersome when mounted, and its sealing effect is also not ideal.
The purpose of this utility model is: provide a kind of and need not make the fast holding pipe joint that screw thread and sealing effect better, do not need sealing rubber pad on connected pipeline.
The utility model is to constitute like this: it comprises joint body (1), internal thread a is arranged in joint body (1) and boss b is arranged at the one end, interior cover (2) and screw thread column sleeve (3) are housed in joint body (1), the bottom of interior cover (2) contacts with boss b, the outside thread of screw thread column sleeve (3) is connected with the internal thread a of joint body (1), the endoporus of interior cover (2) and screw thread column sleeve (3) all is the cone hole, in the cone hole of interior cover (2) and screw thread column sleeve (3), pipe connector sleeves (4) is housed, the outer surface of pipe connector sleeves (4) is the little conical surface in two broad in the middle, and this conical surface is consistent with the tapering of the inner cone body opening of interior cover (2) and screw thread column sleeve (3) respectively; On the periphery of joint body (1), also can be evenly distributed with 2～8 convex tendon c.
Owing to adopted technique scheme, the utility model is compared with existing pipe coupling, not only have in use and need on connected pipeline, not make the advantage of screw thread, do not need in pipe joint, to use rubber seal or rubber gasket can reach the advantage of better seal effect but also have.During use, earlier screw thread column sleeve (3) is screwed out one section, can unclamp pipe connector sleeves (4) like this, two pipelines (5) that will need then to connect inject two of pipe connector sleeves (4) respectively, swivel joint body (1), can screw thread column sleeve (3) be tightened by its internal thread a, by the cone hole of interior cover (2) and screw thread column sleeve (3) and the conical surface of pipe connector sleeves (4) pipe connector sleeves is compressed like this, thereby make it closely connected two pipelines be held tightly and be connected as a single entity.Because the utility model need not make screw thread on pipeline, and do not need when mounted with annexes such as rubber seal, therefore adopt the utility model construct very convenient, save time, laborsaving.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment of the present utility model: joint body (1), interior cover (2), screw thread column sleeve (3) can adopt metal or plastic materials to make, pipe connector sleeves (4) preferably adopts has certain elasticity and intensity plastic materials making preferably, during making, in joint body (1), produce internal thread a and produce boss b at the one end, in joint body (1), load onto interior cover (2) and screw thread column sleeve (3), and the bottom of interior cover (2) contacted with its boss b, and the outside thread of screw thread column sleeve (3) is made into and can be connected with the internal thread a of joint body (1), the endoporus of interior cover (2) and screw thread column sleeve (3) all is made as the cone hole, in the cone hole of interior cover (2) and screw thread column sleeve (3), load onto pipe connector sleeves (4), the outer surface of pipe connector sleeves (4) is made as the little conical surface in two broad in the middle, and make this conical surface consistent with the tapering of the inner cone body opening of interior cover (2) and screw thread column sleeve (3) respectively, instrument easy to use is installed in order to install, be preferably in when making joint body (1), on its periphery, produce equally distributed 4 or 6 convex tendon c simultaneously and get final product.
Claims (2)
1, a kind of fast holding pipe joint, it comprises joint body (1), it is characterized in that: internal thread a is arranged in joint body (1) and boss b is arranged at the one end, interior cover (2) and screw thread column sleeve (3) are housed in joint body (1), the bottom of interior cover (2) contacts with boss b, the outside thread of screw thread column sleeve (3) is connected with the internal thread a of joint body (1), the endoporus of interior cover (2) and screw thread column sleeve (3) all is the cone hole, in the cone hole of interior cover (2) and screw thread column sleeve (3), pipe connector sleeves (4) is housed, the outer surface of pipe connector sleeves (4) is the little conical surface in two broad in the middle, and this conical surface is consistent with the tapering of the inner cone body opening of interior cover (2) and screw thread column sleeve (3) respectively.
2, fast holding pipe joint according to claim 1 is characterized in that: on the periphery of joint body (1), be evenly distributed with 2～8 convex tendon c.
