    • PURPOSE:To enable to easily manufacture the protective cover, which protects the piping for air conditioner as an undivided whole and has excellent weather resistance and safety and offers fine finish, by a method wherein extrusion- coating plastic material is extrusion-coated onto the outer periphery of insulating hoses, provided with the gaps for drain hoses or for leading-in electric wires thereonto. CONSTITUTION:When the integral forming of the insulating hoses 1 and 2 for leading-in of piping for air conditioning and the drain hose holes or guide rope holes for leading-in of electric wires is performed, the piping protective cover is manufactured by extrusion-coating the extrusion coating plastic material (for example, soft polyvinyl chloride, polyethylene resin or the like) 7 onto the outer periphery of the insulating hoses (for example, foam of expanded polyethylene, expanded polyurethane or the like) 1 and 2, provided thereonto with the gaps 8 for passing the drain hoses or the guide ropes by insertion for leading-in electric wires 3 and 4.
    • 目的:为了方便地制造保护罩,保护空调管道不分散,具有优异的耐候性和安全性,并提供精细的表面处理,其中挤出涂覆塑料材料被挤压涂覆在外部 绝缘软管的周边,设置有用于排水软管的间隙或其上的引入电线。 构成:进行用于空调管道导入的绝缘软管1和2的整体形成以及用于引入电线的排水软管孔或引导绳索孔时,管道保护盖通过挤出 - 将挤出涂覆塑料材料(例如,软质聚氯乙烯,聚乙烯树脂等)7涂覆在隔热软管的外周(例如发泡聚乙烯泡沫,发泡聚氨酯等)1和2上, 具有用于通过插入导入电线3和4而通过排水软管或引导绳的间隙8。

    • PURPOSE:To block securely the through holes of a pipe and end by inserting and contacting the special blocking member into the end of the perforated pipe having the many through holes shaped in the pipe wall parallel to the axis. CONSTITUTION:When the through holes 1 of the end of the pipe 2 in which many through holes are shaped parallel to the pipe axis in the pipe wall is blocked, the blocking member 3 is inserted into the end of the pipe 1, the neighborhood of the inserted part is heated and softened, and both are pressed. The blocking member is composed of the outer flange wall 4 fitted to the outside periphery of the perforated pipe, the inner flange wall 5 fitted to the inside periphery and the ring plate 6 connecting the ends of these walls, and the ring plate 6 is made to shape the bottom surrounded by the flange walls 5, 6 and the bottom face to meet the end face of the perforated pipe 1. And many protrusions 7 which are to be inserted to the through holes 2 are provided in the flange wall side of the ring plate 6.
    • 目的:通过将特殊阻挡构件插入和接触多孔管的端部,牢固地堵塞管道的通孔并将其接触,该多孔管具有平行于轴线的管壁中形成的许多通孔。 构成:当管道2的端部中的多个通孔与管壁中的管轴平行的通孔1被阻塞时,阻塞构件3插入到管1的附近, 插入部分被加热和软化,并且两者都被按压。 阻挡部件由与穿孔管的外周嵌合的外侧凸缘壁4,与内周嵌合的内侧凸缘壁5和连结这些壁的端部的环状板6和环状板6构成 以形成由凸缘壁5,6和底面包围的底部,以与穿孔管1的端面相遇。并且,插入到通孔2中的许多突起7设置在穿孔管1的凸缘壁侧 环板6。
