Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a firm type pipe joint flange, includes water receiving pipe 1, and a pot head of water receiving pipe 1 is equipped with plastic sleeve 2, and the other end of water receiving pipe 1 is equipped with ring flange 4, has seted up mounting hole 5 on the ring flange 4, and the internally mounted of mounting hole 5 has supporting bolt 7, has attacked internal thread 3 on the inner wall of water receiving pipe 1, and the axle inner tube 6 is installed through internal thread 3 in the inside of water receiving pipe 1.

In this embodiment, preferably, the flange plate 4 is of an annular structure, and the flange plate 4 and the water receiving pipe 1 are of an integrated structure formed by injection molding at one time, so that the integrated structure is more stable during jointing, seams are reduced, and the possibility of water leakage and water seepage is reduced while the stability is better.
