CN205136902U - Plastic tube material connector - Google Patents

Abstract

The utility model discloses a plastic tube material connector, it includes connecting pipe, connecting pipe's both ends and centre are equipped with annular steel band respectively, the surface of annular steel band scribbles the polyethylene layer, be equipped with control plastic tube material depth of inter fit's spacing arch in the connecting pipe. Connecting pipe includes parallel connecting pipe and right angle connecting pipe. The utility model has the advantages of reasonable design, convenient to use receives outside extrusion back with connecting pipe after the plastic tube material sweat soldering, and annular steel band bears the external pressure, prevents that the interface from taking place deformation, and the plastic tube material connector that has effectively solved prior art receives the easy technical problem who takes place the fracture after the external force.

Description

A kind of plastic pipe connecting head

Technical field

The utility model belongs to plastic pipe production technical field, relates to a kind of plastic pipe connecting head.

Background technique

Prior art feedwater, draining great majority adopt plastic pipe, and plastic pipe adopts the material such as polyethylene, polypropylene to have corrosion-resistant, that intensity is high advantage, is used widely in daily life.The connection of plastic pipe uses connecting head to adopt the mode of sweat soldering.Although the tubing after welding and connecting head combine together, its intensity step-down, easily ftractures after being especially subject to external force, and impact normally uses.

Summary of the invention

The purpose of this utility model is the technical problem that cracking easily occurs after the plastic pipe connecting head of solution prior art is subject to external force, provides a kind of plastic pipe connecting head, to overcome the deficiencies in the prior art.

To achieve these goals, a kind of plastic pipe connecting head of the utility model, it comprises coupling pipe elements; Its main points are that the two ends of described coupling pipe elements and centre are respectively equipped with ring steel belt; The surface of described ring steel belt scribbles polyethylene layer; The spacing preiection controlling plastic pipe insertion depth is provided with in described coupling pipe elements.

Described coupling pipe elements comprises parallel coupling pipe elements and angle coupling pipe fitting.

The utility model reasonable in design, easy to use, after being subject to external compression with the coupling pipe elements after plastic pipe sweat soldering, ring steel belt bears external pressure, preventing interface generation deformation, easily there is the technical problem of cracking in the plastic pipe connecting head efficiently solving prior art after being subject to external force.

Embodiment

According to Fig. 1 and Fig. 2, a kind of plastic pipe connecting head, it comprises coupling pipe elements 3; The two ends of described coupling pipe elements and centre are respectively equipped with ring steel belt 1; The surface of described ring steel belt scribbles polyethylene layer; The spacing preiection 2 controlling plastic pipe insertion depth is provided with in described coupling pipe elements.

Described coupling pipe elements comprises parallel coupling pipe elements and angle coupling pipe fitting.

Plastic pipe and coupling pipe elements sweat soldering, the coupling pipe elements after welding is placed in body of wall or is embedded in inferior when being easily subject to the environment of external force, and ring steel belt bears external pressure, prevents interface generation deformation.Ring steel belt appearance scribbles polyethylene layer can not by corrosion, and its life-span is equal to plastic pipe and coupling pipe elements, and the technical problem of cracking easily occurs after being subject to external force the plastic pipe connecting head that the utility model efficiently solves prior art.

Claims (1)

1. a plastic pipe connecting head, it comprises coupling pipe elements; It is characterized in that two ends and the centre of described coupling pipe elements are respectively equipped with ring steel belt; The surface of described ring steel belt scribbles polyethylene layer; The spacing preiection controlling plastic pipe insertion depth is provided with in described coupling pipe elements.
