Furthermore, the outer wall of the metal insert end is of a polygonal structure, so that the threaded joint can be screwed down when the pipe fitting is used conveniently.

Furthermore, the inner wall of the metal insert is provided with internal threads, so that the metal insert can be conveniently butted with other parts.

Furthermore, the outer wall of the metal insert is provided with external threads, so that the metal insert can be conveniently butted with other parts.

Furthermore, the metal insert is provided with an annular flanging which wraps the end face of the metal insert end, and the annular flanging can tightly wrap the end face of the metal insert end of the plastic pipe fitting, so that the metal insert is effectively prevented from loosening and falling off.

Furthermore, the outer wall of the female end is provided with scale marks, so that alignment between the pipe fitting and the pipe fitting is facilitated.

Furthermore, the material of plastic pipe spare is PB or PPR or PE or PVC, and stability is high.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses a port inner wall of the female end of the plastic pipe fitting of injection molding pipe fitting is provided with the inner groovy, when the connected mode of pipe fitting is hot melt butt joint, unnecessary colloidal sol can flow into the inner groovy, can effectively fix tubular product on the one hand and prevent that tubular product from inserting partially, on the other hand can see unnecessary colloidal sol outside after colloidal sol flows into the inner groovy, make the finished product after the hot melt welding more pleasing to the eye; the metal insert is provided with the annular flanging which wraps the end face of the metal insert end, and when the pipe fitting is subjected to injection molding, the annular flanging can tightly wrap the end face of the metal insert end of the plastic pipe fitting, so that the formation of a gap is effectively avoided, the metal insert is prevented from loosening and falling, and water leakage is avoided.
