Abstract
一种钢丝增强塑料弹簧管包括螺旋状的增强筋和作为管壁的塑料膜,所说的增强筋以钢丝为芯线,其外裹以塑料。增强筋的截面位于钢丝增强塑料弹簧管内周面的通径之外。这种管子柔软性和强度较大,特别是径向内外耐压较大。
Description
本实用新型在国家专利分类表中属于工程元件或部件范围,特别涉及钢丝增强塑料弹簧管。
在公知公用技术中,弹簧管由塑料筋和塑料膜组成,它的材质决定了强度较低、柔软性较差的弱点。
本实用新型的任务是提供一种钢丝增强塑料弹簧管。它的强度、柔软性指标较高。
任务是这样实现的:钢丝增强塑料弹簧管至少包括增强筋和作为管壁的塑料膜,其特征在于增强筋以螺旋状的钢丝为芯线,外裹塑料,它的截面位于钢丝增强塑料弹簧管内周面的通径之外。
按上述方案制成的钢丝增强塑料弹簧管,由于增强筋的芯线为钢丝,所以其强度和柔软性等指标有明显的提高,特别是径向内外耐压明显提高。
附图为本实用新型的示意图(右部剖视、局部放大)。
实施时,增强筋以钢丝3为芯线,制成螺旋状,芯线外裹以塑料2。在螺旋状的增强筋外,套以塑料膜1制成塑料管。由于塑料膜1收缩,增强筋相对向外突出,即增强筋的截面位于钢丝增强塑料弹簧管内周面的通径之外。在实际制造时,可以用挤出机热挤出卷绕连续成形生产。
