Further, the first described hook and the connection part of the second hook are skewed.
Further, the first described hook and the afterbody of the second hook are equipped with fastening firmly circular time hook structure.
Further, described metal tube is circular hollow tube.
Further, described sealing layer is the circular hollow tube that inner tubal wall is smooth.
Further, described elastic protective layer for outer tube wall be the circular hollow tube of wave-like type.
Further, described sealing layer adopts high resilience sealing material to make; Described elastic protective layer adopts high resilience material to make.
Metal mutual sleeve tube of the present invention can adopt stainless steel belt or Galvanized Steel Strip, corrosion resistance and good.
Elastic protective layer of the present invention adopts high resilience material, and section configuration is wave-like type, ensure that wear-resisting, the anti-bending strength of metallic hose, and further increases the bearing capacity of metallic hose.Described sealing layer adopts high resilience sealing material, ensure that the sealing of metallic hose, and inner tubal wall is smooth, can reduces the flow resistance of fluid in pipe, reduces the pressure loss, improves efficiency of transmission, and extends the working life of metallic hose.
Beneficial effect of the present invention is embodied in: structure is simple, bearing capacity is strong, the pressure loss is little and meet high pressure, seal request, can be used for conveying high-pressure fluid.
