RELATED APPLICATIONS CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to the utility model patent application No. 201020224161.6, entitled "Stretching Hose", submitted to the State Intellectual Property Office of China on June 12, 2010, the entire contents of which are incorporated by reference. Joined in this application. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose for containing/delivering a fluid, a semi-fluid or a containment wire for delivering electrical energy, and more particularly to a hose having a separate axial tensile load-bearing structure. BACKGROUND OF THE INVENTION Hose is generally used to contain and transport fluids (gas, liquid), semi-fluids (pastes), and contain wires to deliver electrical energy. The functions required for the hose include: containment isolation, internal and external pressure, gravity of the load-bearing pipe and objects in the pipe, and the various component forces and load-carrying axial forces generated by gravity when carrying the suspension. At present, the structure of the hose is various, and is generally a single-tube structure of one pipe body or a multi-tube structure including a plurality of pipe bodies, and the pipe wall of the pipe body is generally a single-layer structure or a multi-layer structure. However, for the structure of these hoses, when the axial tensile force exceeds the load carrying capacity of the existing structural pipe itself, the pipe wall will have problems such as elongation deformation, cracking, and interlayer displacement. In order to solve this problem, the pipe wall of the pipe body can also be solved by a reinforcing layer structure with a higher load carrying capacity, but this method increases the minimum bending radius of the pipe and affects the application range of the hose. SUMMARY OF THE INVENTION The present invention is directed to the disadvantages of the prior art described above, and provides a pipe wall that does not need to be reinforced for axial tension, has good tensile strength, a small minimum bending radius, good overall flexibility, simple manufacturing process, and convenient installation and fixation. Low cost tensile hose. In order to solve the above technical problem, the technical solution adopted by the present invention is: a tensile hose, comprising: a pipe body connected to a pipe wall and at least one casing, wherein the casing is provided with a supporting rope . The following scheme is a further improvement of the present invention: The tube body and the sleeve are arranged side by side in sequence; the carrier rope is adhered to the inner wall of the sleeve integrally, or a gap is provided between the carrier rope and the inner wall of the sleeve; The utility model has a fixed buckle; the utility model is composed of a two-piece manifold body and a single sleeve, and the two tube body are respectively disposed on both sides of the sleeve; or, it is composed of a tube body and a sleeve; The body and the adjacent tube body of the at least one sleeve and/or the tube wall of the sleeve are spaced apart by a predetermined distance of 3 and are connected by a joint; the adjacent tube body and/or the outer wall of the sleeve The connecting portion is a plate-like connecting portion integral with the pipe wall; the thickness of the plate-shaped connecting portion is equal to the thickness of the pipe wall of the adjacent pipe body or the casing; the pipe body and at least one a common tube wall between adjacent tube bodies and/or sleeves in the bore; the tube body and the adjacent tube body and/or sleeve of the at least one sleeve are bonded; The tensile hose includes one of the tube body and a plurality of strands around the tube body centered on the tube body The sleeve; or the sleeves that are stranded with each other and between the sleeve and the tube body. The invention has the following advantages: The invention bears the axial tensile force of the hose through the supporting rope in the casing, and the pipe body only needs to carry the function of the body, so the pipe wall does not need the reinforcing structure and carries the larger axial direction. When the tension is pulled, the pipe wall is not elongated, and the utility model has the advantages of good tensile strength, small rigidity, small weight, simple manufacturing process and low cost. The tube body and the sleeve of the present invention can also be arranged side by side in order, so that the tensile hose can still be bent to the side when having a plurality of tube bodies and sleeves, the minimum bending radius is small, and the overall flexibility is good; The ends can also be provided with fixing buckles, which makes the loading and fixing of the supporting ropes more convenient and quick.

In this embodiment, a gap is provided between the carrier rope 3 and the inner wall of the sleeve 2, and the carrier rope 3 can slide in the sleeve 2, so the tensile hose of the embodiment is particularly suitable for the carrier rope 3 and the sleeve 2 The coefficient of thermal expansion is different and the hose is horizontally fixed. The carrier rope 3 of the present invention may be a single-strand or multi-strand structure, and may be made of a metal or a non-metal material. In this embodiment, the carrier rope 3 is a single-strand metal wire, and of course, it may be used as a wire rope. Stranded rope structure. As shown in FIGS. 3 and 4, the tensile hose of the second embodiment of the present invention is substantially the same as the first embodiment, and the difference is as follows: 7 The carrier rope 3 is adhered to the inner wall of the sleeve 2 in one body. Therefore, the tensile hose of the present embodiment is suitable for the case where the thermal expansion coefficient between the carrier rope 3 and the sleeve 2 is similar, and is particularly suitable for the case where the hose is vertically fixed. When the hose is vertically fixed, the axial tensile force is The inner wall of the sleeve 2 is hooked on the carrier rope 3, so that the tube wall can be prevented from being elongated or broken due to uneven force. As shown in FIG. 5, FIG. 6, and FIG. 7, the tensile hose of the third embodiment of the present invention is composed of two pipe bodies 1 and a pipe sleeve 2, and the pipe body 1 and the pipe sleeve 2 are arranged side by side, two The root canal bodies 1 are respectively disposed on both sides of the sleeve 2. The middle sleeve 2 is provided with a carrier rope 3, and a gap is provided between the carrier rope 3 and the inner wall of the sleeve 2. The carrier rope 3 can slide in the sleeve 2, and the two ends of the carrier rope 3 are respectively provided with fixing buckles 31. Therefore, when the hose is fixed, the fixing buckle 31 can be quickly and conveniently fixed. Further, the hose body 11 is provided at both ends of the pipe body 1. As shown in Figs. 8 and 9, the tensile hose of the fourth embodiment of the present invention is substantially the same as the third embodiment, and the difference is that the carrier rope 3 is adhered to the inner wall of the sleeve 2 as one body. In each of the above embodiments, the adjacent pipe body 1 and the pipe wall of the sleeve 2 are spaced apart by a predetermined distance and connected by a joint. As can be seen from Figures 2, 4, 6 and 9, the connection between the tube body 1 and the tube wall of the sleeve 2 is provided as a plate-like connection. In an embodiment not shown, the tensile hose may comprise a plurality of sleeves 2 or further comprise a plurality of tube bodies 1.
