Embodiment 1

[0016] Such as figure 1 , figure 2 , a fast spiral wound drainage pipe joint, including a first insert 1 and a second insert 2, the first insert and the second insert are PE injection molded parts, have the same inner diameter, can be made into finished products in the factory, in the first The outer side of the plug-in 1 is provided with steel belt reinforcing ribs 11 to improve its rigidity. One end of the first plug-in 1 is provided with a ring-shaped flange 12, and the other end is an insertion part 13 matched with the pipe material; The fitting part 13' of the pipe material, the flange and the card slot realize the clamping connection, and at the same time of the clamping, an annular rubber pad 3 with an L-shaped cross-section is provided between the flange and the card slot , the overall sealing effect is good, and there will be no water leakage.

Embodiment 2

[0018] The first plug-in and the second plug-in have different inner diameters, which can realize quick connection of two different pipe materials.

Abstract

A rapid spiral winding dewatering tube joint relates to a connector. The rapid spiral winding dewatering tube joint comprises a first inserting piece and a second inserting piece. An annular flange platform is arranged at one end of the first inserting piece, an inserting portion matched with a tubular product is arranged at the other end of the first inserting piece, an annular clamping groove is arranged at one end of the second inserting piece, an inserting portion matched with the other tubular product is arranged at the other end of the second inserting piece, clamping connection between the flange platform and the clamping groove is achieved, and an annular rubber pad with an L-shaped cross section is arranged between the flange platform and the clamping groove. A transition inserting piece achieves rapid connection of a spiral winding dewatering tubular product, a normal connecting mode that a plurality of layers are needed for wrapping is changed, connection speed can be effectively improved, and connection cost is reduced.

Description

technical field [0001] The invention relates to a pipe joint of a large-diameter drainage pipe, in particular to a fast spiral winding pipe joint of a drainage pipe. Background technique [0002] in the field of drainage pipes. Polyethylene is often used to wind pipes. In order to improve the rigidity of this pipe, it is usually necessary to make steel strip reinforcement ribs on the outside, so the interface of the drain pipe with this structure is very complicated. The common practice is to form the interface by thermal welding or multi-layer cladding, such as the solution disclosed in Chinese patent 2011205321975. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a fast spiral-wound drainage pipe joint to increase the connection speed and reduce the connection cost. [0004] The technical solution adopted by the present invention to solve the technical problem is: a fast spiral winding drainage pipe ...
