Non-skid telescopic sleeve pipe

防滑式伸缩套管

Abstract

The utility model discloses a non-skid telescopic sleeve pipe. The non-skid telescopic sleeve pipe comprises two types, namely a non-skid heat-shrinkable sleeve pipe and a non-skid cold-shrinkable sleeve pipe; at least one outward projecting part which projects outwards in the longitudinal direction is arranged on the outer wall surface of the non-skid telescopic sleeve pipe; as the outward projecting part is formed in a longitudinal outward projecting way, a corresponding groove can be formed in an extrusion die of the machine head of an extrusion machine for the sleeve pipe in the manufacturing process, and the outward projecting part which projects outwards in the longitudinal direction can be formed in the extruding process; the outward projecting part can improve the hand feel and achieve the non-skid and decorative effects; and compared with the method of finishing a 'reversed hair' pattern area by a manual licker-in grinding, sanding, sand blasting or hair collecting process, automatic production is achieved, the process is simple, and the labor and time costs are reduced, so that the production cost can be reduced.
本实用新型公开一种防滑式伸缩套管,该防滑式伸缩套管分为防滑式热缩套管与防滑式冷缩套管两种类型,防滑式伸缩套管的外壁面具有至少一沿纵向向外凸伸的外凸部,由于该外凸部沿纵向向外凸伸形成,在制造时,可在套管的挤出机机头的口模上设置相对应的凹槽,进而能够在挤出时即可形成沿纵向向外凸伸的外凸部,外凸部能改善手感,达到防滑和装饰的效果,与人工进行刺磨、砂磨、喷砂或粘毛工艺才能完成“翻毛皮”花纹区域相比,实现了自动化生产,工艺简单,减少人力与时间成本,从而能够降低生产成本。
