Problems solved by technology

The first and last ends of the lined bellows in the outer spiral ribs are freely combined with the outer extrusion coating material, causing the appearance of the product to sometimes warp, sometimes collapse, and the coating layer is sometimes less material, Sometimes there are too many materials, so the product has the defects of poor appearance, poor quality, low strength and instability. Therefore, the deficiencies of existing products need to be improved urgently

Embodiment 1

[0023] Such as Figure 1 to Figure 3 As shown, a spiral rib lining transition piece for a carat tube, which includes a vertebral body 1, and the end of the large diameter of the vertebral body 1 is provided with a socket 2, and the socket 2 is an elastic socket, and the outer surface of the transition piece There are clearly staggered blind grooves 3, and the transition piece is connected with the inner bellows at the first and last ends of the spiral ribs on the periphery of the carat tube by means of the socket 2.

[0024] The lining transition piece is composed of a cone 1 and a socket 2. The entire outer surface is provided with staggered and distinct blind grooves 3, and is formed by injection molding, so that the lining transition piece can rotate 360 ​​degrees along the axis. Free bending, high strength; its cone 1 structure can be a reasonable transition from small to large and from large to small for the lining bellows at the first and last ends of the outer spiral ri...

Abstract

The invention belongs to the field of drainage and sewage discharge pipelines and particularly relates to a spiral reinforcement liner transitional piece of a Krah pipe. The spiral reinforcement linertransitional piece of the Krah pipe comprises a cone, the large-caliber end of the cone is provided with an insertion opening which is elastic, the outer surface of the transitional piece is providedwith staggered blind slots, and the transitional piece is connected with liner corrugated pipes at the head end and the tail end of a spiral rib on the periphery of the Krah pipe through the insertion opening. The transitional piece has the advantages that the structure is simple and novel, the size is stable, and production is quick; and after the transitional piece is connected with the liner corrugated pipes in the rib of the periphery of the Krah pipe for use, the head end and the tail end of the spiral rib on the periphery of the Krah pipe are smooth, and the appearance is good.

Description

technical field [0001] The invention belongs to the field of drainage and sewage pipelines, in particular to a spiral-rib liner transition piece for carat pipes. Background technique [0002] At present, the large-diameter pipe produced in China - HDPE reinforced hollow wall winding pipe (Type B), referred to as carat pipe. The first and last ends of the lined bellows in the outer spiral ribs are freely combined with the outer extrusion coating material, causing the appearance of the product to sometimes warp, sometimes collapse, and the coating layer is sometimes less material, Sometimes there are too many materials, so the product has the defects of poor appearance, poor quality, low strength and instability. Therefore, the deficiencies of existing products need to be improved urgently. Contents of the invention [0003] In order to overcome at least one of the above-mentioned defects in the prior art, this patented product provides a transition piece for a spiral rib l...
