The utility model relates to a winding pipe, which comprises a plastic layer and coated on the reinforcing bar of the plastic layer, which is characterized in that the plastic layer is composed of a plastic spiral wound together, and two adjacent ring plastic sheet at the edges overlapping fusion the overlap region with spiral shape the formation of the plastic layer, the reinforcing rib is matched with the shape of the overlapping zone spiral spring shape and embedded in the overlapping area. The winding pipe of the utility model has the advantages of simple structure, only by a plastic sheet and a reinforcing rib wound into the inner wall of the pipe body, smooth preparation, use process is not easy to accumulate dust and other debris; strengthen the reinforcement area just below the plastic sheet, at high temperature the inner and outer layers of plastic sheet complete welding pipe makes the whole structure is firm, has long service life; the utility model does not need winding tube stiffeners on peripheral pre coating adhesive layer, strengthen spring elastic gluten formation is good, but from the tube body of high strength, good bearing capacity.

技术介绍
常用于吸尘器、通风装置、抽油烟机、排水设备中的塑料软管多是通过挤出或吹塑等方法得到的,这样的塑料软管制作简单、制备成本低,但其承压、抗压能力也较差,于是人们通过在塑料软管内嵌入加强筋来改善其承压、抗压能力。授权公告号为CN202674804U的中国技术专利《塑钢缠绕管》(申请号:CN201220334432.2)披露了一种结构,其包括一聚乙烯内管、缠绕层和聚乙烯外保护层,缠绕层由高强度过塑钢丝制成,上述缠绕管中的缠绕层为螺旋形钢丝网结构,是由左螺旋钢丝与右螺旋钢丝相互交织而成。上述缠绕管在生产时,聚乙烯外保护层缠绕的松紧度难以控制,如果缠绕过紧,由于塑料挤出机挤出的塑料片温度较高,塑料层与缠绕层接触后受到向上的力过大容易导致塑料层破损;而如果缠绕较松,塑料片虽然可以将缠绕层覆盖并与聚乙烯内管熔接在一起,但塑料层与缠绕层之间特别是螺旋钢丝周围会形成较大的空隙,这就严重影响了管体的整体强度及使用寿命。授权公告号为CN203322531U的中国技术专利《大口径低压给水聚乙烯丝网缠绕管及其生产设备》(申请号:CN201320414179.6)披露了一种结构,其中,缠绕管由实壁管体层及外凸增强结构层构成,实壁管体层由内壁层、增强层及外壁层构成,内壁层为片状聚乙烯条带螺旋缠绕于滚筒模具表面形成的连续内壁层;增强层为钢丝网带螺旋缠绕于内壁层外而成钢丝网增强层;外壁层为片状聚乙烯条带螺旋缠绕于滚筒模具表面形成的连续外壁层;外凸增强结构层为由包覆骨架管的管状聚乙烯条带螺旋缠绕于实壁管体层的外壁层外表面形成 ...
