DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Advantages and features of the inventive concept and methods of accomplishing the same may be understood more readily by reference to the following detailed description of embodiments and the accompanying drawings. The inventive concept may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0014] Referring to FIG. 1 through FIG. 3, FIG. 1 is a perspective view of the compressive heat-resistant tube structure for RV of the present invention. FIG. 2 is an exploded view of the compressive heat-resistant tube structure for RV of the present invention. FIG. 3 is a side sectional view of the compressive heat-resistant tube structure for RV of the present invention.

[0015] The compressive heat-resistant tube structure for RV of the present invention comprises a compressive heat-resistant multi-layer tube 10. The compressive heat-resistant multi-layer tube 10 comprises a compressive heat-resistant PVC soft inner tube 11, a polyester dense crocheted covering layer 12, and a compressive PVC soft outer tube 13. An outer surface of the compressive PVC soft outer tube 13 is provided with an identification surface layer portion 130. The compressive heat-resistant PVC soft inner tube 11 is wrapped by the polyester dense crocheted covering layer 12. The polyester dense crocheted covering layer 12 is wrapped by the compressive PVC soft outer tube 13.

[0016] Through the cooperation of the above-mentioned structure, the compressive heat-resistant tube structure for RV of the present invention is accomplished.

FIG. 3 is a side sectional view of the compressive heat-resistant tube structure for RV of the present invention. FIG. 4 is a schematic view of the compressive heat-resistant tube structure for RV of the present invention applied to a camping car. The compressive heat-resistant PVC soft inner tube 11 is made of a material suitable for drinking water. The polyester dense crocheted covering layer 12 is made of polyester wires and formed in a dense-knitted crocheting manner. The compressive heat-resistant PVC soft inner tube 11 is wrapped by the polyester dense crocheted covering layer 12. The polyester dense crocheted covering layer 12 is wrapped by the compressive PVC soft outer tube 13. The compressive heat-resistant PVC soft inner tube 11 is used to deliver drinking water. Through the cooperation of the compressive heat-resistant PVC soft inner tube 11, the polyester dense crocheted covering layer 12 and the compressive PVC soft outer tube 13, the pressure resistance of the compressive heat-resistant multi-layer tube 10 can be improved to 300 PSI. The configuration of the soft tube is flexible, so that the compressive heat-resistant multi-layer tube 10 can be directly bent at a corner position when it is applied to a camping car, without the need for cutting tubes and fitting of the other corner fittings. The arrangement of the identification surface layer portion 130 allows the user to easily and quickly identify each tube for connection of the tubes. The soft compressive heat-resistant multi-layer tube 10 can be bent according to the demand of use, not limited to the arrangement of the edge wiring so as to reduce the required parts and the labor cost. The soft compressive heat-resistant multi-layer tube 10 is convenient for use and can be installed conveniently.
