Abstract

The utility model relates to an aluminium plastic composite pipeline joint, comprising a core barrel of the joint, a washer, a sealing ring, a C-shaped ring and a nut, wherein the outer wall of the core barrel of the joint is provided with occlusive teeth and the sealing ring; a connected pipeline achieves high bond strength and sealing performance at the occlusive teeth and the sealing ring at the outer wall of the core barrel of the joint. The upper surface and the lower surface of the cylindrical outside surface of the core barrel of the joint are opened with planes, which is easy to install and material saving. The utility model is applied to the connection of plastic pipes and aluminium plastic composite pipes and has the advantages of easy installation, high intensity, good sealing performance, anti-rust and material saving qualities.

Description

A kind of aluminium-plastic composite pipe pipe coupling

Technical field:

The utility model relates to a kind of pipe coupling, is applicable to that the pipeline of plastic tube or aluminium-plastic composite pipe connects.

Background technique:

At present, the pipe coupling variety type is a lot.The jointing of widespread usage is that socket wrench specially adapted for it directly is connected with pipe joint, perhaps adopts thread type to connect its link cost height, installation difficulty is big, because thread type joint unbalance stress leaks after using a period of time easily, make troubles for construction operation in enormous quantities.

Summary of the invention:

The invention provides a kind of adhesive strength height, good sealing effect, the convenient aluminium-plastic composite pipe pipe coupling of installing, saving material.

The pipe coupling that the utility model provides is made up of joint core pipe, packing ring, seal ring, C type ring and nut, wherein:

The utility model pipe coupling is provided with tooth engaged at the joint core tube wall, tooth engaged is the teeth mode, the teeth direction of teeth mode is consistent with the pipeline direction of insertion, have circular groove at the joint core tube wall, seal ring is housed in the circular trough, joint core pipe outside is with nut, on nut spigot core pipe, be with C type ring simultaneously, between C type ring inner end and the joint core pipe packing ring is housed, and leave the plane at the joint core pipe outer cylinder upper and lower surface of facing the wall and meditating, at last, with spiral marking connection, make the whole pipe joint become one between nut and the joint core pipe.

The utility model compared with prior art has simple in structurely, and processing and fabricating is easy, and is easy to install, and maximum characteristics adhesive strength is good, good sealing effect, and the life-span is long, saves raw material.

Description of drawings:

Fig. 1 is the utility model assembling schematic representation;

Fig. 2 is the utility model exploded view;

Fig. 3 is the utility model packing ring projection drawing.

Embodiment:

Concrete structure is as shown in drawings: 1 is joint core pipe, 2 is packing ring, 3 is seal ring, and 4 is C type ring, and 5 is nut, the joint core tube wall is provided with tooth engaged 1A, ring shaped slot 1B is equipped with seal ring 3 in ring shaped slot 1B, the pipe coupling outer cylinder upper and lower surface of facing the wall and meditating is left plane 1C, the convenient installation saved material.C type ring 4 is housed in nut 5, be enclosed within by the outside of jointed tubular workpieces, on joint core pipe, be with packing ring 2 simultaneously, for the aluminium lamination that prevents to be taken over contacts with joint core pipe, produce corrosive action, taken over the tooth engaged place of road after the outer C type ring of joint core pipe is shunk by nut pressure and form higher binding strength and better seal effect at the joint core tube wall.
