Abstract

The utility model provides a hot melt connecting pipe fittings which is characterized in that the pipe fittings consists of a pipe fittings body and a sleeve cover of an interface end part; the pipe fittings body and the sleeve cover are made of the material of PP or PE, the pipe fitting can be a straight-through one, a tee joint T, an elbow, a cross joint or a valve; the outside surface of the sleeve cover arranged on the end part of the pipe fittings body can be provided with various patterns; the sleeve cover arranged on the end part of the pipe fittings body can be connected with the pipe fittings body by screw thread, or be directly encased on the pipe fittings body, or be connected with the pipe fittings body by any other means. Compared with the prior art, the utility model has simple structure, easy machining and manufacture, convenient installation and use with the most obvious characteristic that the problem that the overfall by the hot melt connection has a bad effect on the appearance of the connection system after the connection interface is covered by a cover is solved.

Description

A kind of hot melt grafting pipe fitting

Technical field:

The utility model relates to a kind of hot melt grafting pipe fitting, and it comprises the upper shield of main pipe body and end, and the hot melt that is particularly useful for plastic piping is pegged graft.

Background technique:

The kind of pipe coupling at present is a lot, wherein great majority are thread type and clamp-press type pipe discontinuity and cost height, processing request precision height, installation difficulty also are bigger, and seepage takes place long-term use the easily, can not fundamentally solve the seepy question of pipe fitting, and minority is used hot melt grafting pipe fitting, though solved seepage problem, the outer plastic melt of pegging graft is excessive, make the connected system outward appearance rough and uneven in surface, influence the attractive in appearance of whole pipe-line system.

Summary of the invention:

The utility model provides a kind of hot melt grafting pipe fitting, it is characterized in that: this pipe fitting is made of the upper shield (2) of main pipe body (1) and interface end.

In the hot melt grafting pipe fitting that the utility model provides, described main pipe body (1) is PP or PE material pieces with upper shield (2); Pipe fitting can be lead directly to, threeway, elbow, four-way or valve.

In the hot melt grafting pipe fitting that the utility model provides, the cover exterior surface of main pipe body end can be designed to various patterns.

In the hot melt grafting pipe fitting that the utility model provides, the upper shield of main pipe body end can also can directly be enclosed within on the main pipe body by being threaded with main pipe body, can be connected with main pipe body by other any one mode.

The new shape of this practicality compared with prior art, simple in structure, processing and fabricating is easy, and is easy to install, maximum characteristics are that the connection interface place covers after the cap bag, have solved because the outward appearance of the connected system that hot melt connection overflow influences.
