Description

Plastic adaptor

Technical field:

The utility model relates to a kind of plastic adaptor that is used to be connected and fixed tubing such as plastics.

Background technique:

Plastic tube is used in the conveying of gas, liquid more and more now, for pipe joint and tubing can be sealed preferably, usually the end of the adapter head of pipe joint and tubing press fit under the state of heating and melting, though such fit can prevent to reveal effectively, but overflow 7 (as shown in Figure 1) appears in seam crossing easily that assemble under the molten state, overflow is sharper after curing, crude, not only scratches the contactee easily, and not attractive in appearance.

Summary of the invention:

The purpose of this utility model is to provide a kind of can effectively cover overflow, and prevents that overflow from scratching people's plastic adaptor, and it is not only simple in structure, easily manufactured, and elegant in appearance.

The utility model comprises having the pipe joint body that two or more take over head, it is characterized in that: described adapter head end mouth peripheral part is provided with belt shade, the big footpath perimembranous inner edge of described belt shade is provided with snapping and carefully encircles A, the corresponding axially movable snapping that is positioned at the outside of shade that prevents to go in ring that is provided with carefully encircles B and is positioned at inboard back-up ring on the described adapter head end mouth peripheral part, the path port in the belt shade outside has the adapter port, is provided with in order to cover the transition joint of joint fusion overflow between described big footpath perimembranous and the adapter port.

The utility model not only can cover overflow effectively by be arranged with the shade that goes in ring on overflow, can not cause personnel's scuffing, and the utility model is simple in structure, it is easy to use, elegant in appearance to make.
