Abstract

The utility model relates to a clamping aluminium plastic composite pipe fitting which belongs to the class of pipeline connection. The utility model comprises a pipe fitting body, an outer steel sleeve, a seal ring and a protective sleeve. The utility model is characterized in that the outside of the pipe fitting body is provided with the protective sleeve; the connecting parts of the protective sleeve and the steel sleeve as well as the protective sleeve and the pipe fitting body are respectively provided with a steel sleeve anticreeping platform and a pipe fitting anticreeping platform to guarantee the firmness of connection; an observation hole is also arranged on the protective sleeve for observing whether the pipe fitting is inserted in place or not. The utility model has the advantages of reasonable structure, light weight, low cost, firm pipe fitting connection and favorable performance, and the protective sleeve uses PVC material.

Description

Clamp-press type aluminium-plastic composite pipe pipe fitting

Technical field

The utility model belongs to pipeline and connects class, specifically is clamp-press type aluminium-plastic composite pipe pipe fitting.

Background technique

Problems such as along with socioeconomic continuous development, aluminium-plastic composite pipe for building also obtains extensively comprehensively using, and generally there is Heavy Weight in the clamp-press type pipe of the pipeline connecting parts employing supporting with it, underaction is light and handy, cost of production is high, structure is reasonable inadequately.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, provide a kind of rational in infrastructure, light and handy flexibly, be connected firmly, superior performance clamp-press type aluminium-plastic composite pipe pipe fitting.

The technical solution of the utility model is as follows:

A kind of clamp-press type aluminium-plastic composite pipe pipe fitting; comprise main pipe body, outer steel sleeve, seal ring, protecting jacket; it is characterized in that: a protecting jacket is arranged outside main pipe body; protecting jacket and steel bushing, main pipe body joint are respectively arranged with steel bushing anticreep platform, pipe fitting anticreep platform, and be insecure to prevent that steel bushing, main pipe body from connecting.

Also be provided with peephole on the protecting jacket of the present utility model, whether plug-in mounting puts in place to be used to observe tubing.

The utility model is simple and reasonable, and protecting jacket adopts the PVC material, and in light weight, cost of production is low, and pipe fitting is connected firmly, superior performance.
