Helical stacked composite hoses

A helical stacked composite hose comprising:

• a helical body being a helical long strip;
• each cross section of the helical body having a flat portion facing toward a center of the helical body;
• an inner cloth being a strong flexible cloth which enclose the helical body so as to form a round cover;
• an inner surface of the inner cloth having a flat cambered shape so that fluid can pass through the inner cloth smoothly;
• a plurality of thin film layers enclosing the inner cloth;
• the film layers winding around the inner cloth several turns;
• an outer cloth being a strong flexible cloth;
• the outer cloth winding around the film layers so as to form as a round cylinder layer;
• an outer helical spring being installed around the outer cloth;
• the outer helical spring having a strong structure and having the effect of protecting the interior structure;
• a rubber cover made of annular soft rubber;
• the rubber cover being formed with a recess;
• the inner cloth, film layers, outer cloth being embedded into the recess and being fixed therein;
• a front end of the rubber cover being formed with an cambered edge so as to make the assembly work easy;
• a ferrule being an annular fixing protecting cover;
• the ferrule enclosing the outer surface of the rubber cover and the outer cloth;
• a front inner side of the ferrule being formed with a tapered opening;
• and
• a joint having a stepped outer layer;
• an interior of the joint being formed as a round hole;
• an end of the joint with a larger outer diameter being formed with thread and another end of the joint with a smaller diameter being formed with a helical structure so as to match with the helical body;
• and a middle section of the joint being used to match with the tapered opening of the ferrule.
