Abstract
The utility model relates to a telescopic pipe joint, consisting of a joint part and a nut. The tail end of the joint part is provided with a section of extending pipeline with a check ring which is sleeved with the nut; the inner diameter of the nut is matched with the outer diameter of the extending pipeline; the mouth of the nut faces to the check ring; the check ring can be arranged at the end of the extending pipeline through screw threads. The utility model is not restricted by the space, pipeline length and mounting conditions when in mounting, which overcomes the defect of inconvenient mounting of the prior art, being characterized by simple structure, good performance, convenient production and low cost.
Description
Technical field
The technical field that the claimed technological scheme of the utility model relates to is a pipeline connecting parts.
Background technique
The pipeline of present various material, various performances emerges in an endless stream, therefore the application of pipe joint also more and more widely, performance requirement to it is also more and more higher, various hose couplings, reducer fitting, interior nipple, threeway four-way etc. have occurred and has had the pipe joint that various usabilities require.With the family is example, use the place of pipeline just more and more now, but the installation of family's pipe laying and industrial pipeline is different, be subjected to the restriction of conditions such as space, decoration situation, erection unit, the stubborn problem common such as us has: just can not connect by pipe joint if length is improper between the pipeline of having fixed; Perhaps when the plastic-aluminum pipe is installed pipe joint with receive again on the fixing pipeline of another root after a pipeline is connected just very difficult; Just can't the mounting pipe joint when two spaces of pipe around the joints of perhaps desiring to couple together are very little or the like, the existing pipe joint of these problems is not but considered when design, therefore it is the existing common disadvantage of pipe joint that installation inconvenience, especially family's installation are inconvenient to.
Summary of the invention
Technical problem to be solved of the present utility model provides and a kind ofly can satisfy usability and require to be convenient to again the pipe joint installed.
The technological scheme that the utility model is made up of connector portions, seal ring and nut solves above technical problem; The connector portions tail end has one section end to be provided with the extensional pipeline of ring washer, and suit nut on the extensional pipeline, and the external diameter of nut internal diameter and extensional pipeline coincide, and the opening of nut is towards ring washer.In the said structure, connector portions can be that the structure of various types of pipe joints in the prior art is to satisfy usage requirement, the connector portions of pipe joint is connected with a pipeline during installation, and the other end is connected with another root pipeline by nut, come collapsing length because nut can be when pipe joint maintains static rotate with axial motion around extensional pipeline, so pipe joint just can not be subjected to the restriction of conditions such as the length of space, pipeline and installation situation when connecting tube.
Existing pipe joint structure generally all more complicated could satisfy various usage requirements, so the structure of the utility model connector portions is generally also complicated, volume is also bigger, under these circumstances, for convenient for production, simplified structure can make ring washer be installed in the end of extensional pipeline by screw thread.In addition, the hand of spiral on the ring washer is opposite with the hand of spiral of nut, makes that the degree of tightness of the degree of tightness of ring washer and nut is reverse each other, and this just can not make ring washer loosening when the fastening nut connecting tube.Extensional pipeline has recessed plane for pipe tongs or spanner clamps whole pipe joint so that the operation of fastening nut near the surface of connector portions in addition.
In view of the plastic-aluminum pipe is belonging to the application period of penetration and promotion at present, consumption is increasing, the utility model can also design a kind of pipe joint of installing and using that is particularly suitable for the plastic-aluminum pipe, and this structure is that connector portions adopts the structure that purges joint, and there is outside thread the connecting part of connector portions and extensional pipeline.
Connector portions of the present utility model can satisfy the performance requirement that connects between the pipeline, when concrete the installation, can at first be connected with a pipeline by connector portions, the other end is connected with another root pipeline by rotatable nut, so just can install in very little space, this situation especially is fit to the installation of plastic-aluminum pipe or other flexible pipe; Moreover the slip by nut changes the length of pipe joint, no matter this just makes length or pipeline between pipeline whether fix and can couple together easily, this situation is highly suitable for the maintenance of house decoration or pipeline.In addition, ring washer of the present utility model is by screw thread and extensional pipeline combination, not only convenient production, simplified structure, reduce cost and help the installation of whole pipe joint, other is positive and negative tooth such as nut thread and ring washer screw thread, has structures such as recessed plane all to make things convenient for the installation of pipe joint further on the extensional pipeline.The utility model has greatly improved the convenience that pipe joint is installed in a word, can utilize the most basic instrument under the condition of all difficulties, pipeline to be coupled together by the utility model, be not only applicable to house decoration, be suitable for using on industrial pipeline, the public pipeline yet.
Description of drawings
Fig. 1 is a preferred embodiment structural drawing.Its component names is that 1-purges structure, 2-connector portions, 3-outside thread, 4-extensional pipeline, 5-nut, 6-nut thread, 7-seal ring, 8-back-up ring internal thread, 9-extensional pipeline outside thread, 10-back-up ring, 11-plane.
Embodiment
Structure shown in Figure 1 is particularly suited for using on plastic-aluminum pipe or other flexible pipe.Connector portions 2 leading portions are for purging structure 1, its tail end has one section extensional pipeline 4, there is outside thread 3 connecting part of connector portions 2 and extensional pipeline 4, and connector portions 2 is inserted in the inner cavity of pipe, is tightened onto to make on the outside thread 3 with a nut again to be connected firmly between them closely.
Suit nut 5 on the extensional pipeline 2, and the external diameter of nut 5 internal diameters and extensional pipeline 4 coincide, and the end of extensional pipeline 4 has outside thread 9, and ring washer 10 is tightened on the extensional pipeline 4 by internal thread 8.The opening of nut 5 is towards ring washer 10, built-in ring 7, the screw thread 6 and the positive and negative each other tooth of ring washer internal thread 10 of nut 5.Extensional pipeline 4 mills out two planes 11 of symmetry near the surface of connector portions 2 in addition.This end mounting type of pipe joint is: 11 clamp whole pipe joint with pipe tongs or spanner from the plane, then nut 5 is docked with the outer silk of waiting to take over, screw nut 5 and compress seal ring 7 and get final product.
