[0029] like Figure 1-5As shown, this utility model discloses a corrosion-resistant rubber hose, comprising a hose body 1. The hose body 1, from the inside out, consists of a corrosion-resistant layer 6, a thermal insulation layer 7, a reinforcing layer 8, and a wear-resistant layer 9. The corrosion-resistant layer 6 is an epoxy resin coating; epoxy resin typically possesses excellent corrosion resistance and good tolerance to many chemicals. The thermal insulation layer 7 is a rubber foam layer; rubber foam can be used for thermal insulation of fluids within the pipe and also provides a certain degree of sound insulation. The reinforcing layer 8 is a glass fiber layer; glass fiber, as a reinforcing material, can significantly improve the strength and durability of the rubber hose. The wear-resistant layer 9 is an alumina coating; the alumina coating greatly improves the wear resistance and oxidation resistance of the rubber hose surface, and as a high-temperature resistant material, alumina allows the rubber hose to operate in high-temperature environments.

[0030] The two ends of the tube body 1 are respectively connected to a first connecting ring 2 and a second connecting ring 3, and multiple support rods 4 arranged in a circumferential array are provided between the first connecting ring 2 and the second connecting ring 3. Both ends of the tube body 1 are provided with external threads 5, and the first connecting ring 2 and the second connecting ring 3 are threaded to the external threads 5. The surfaces of the first connecting ring 2 and the second connecting ring 3 are provided with anti-slip textures. By setting the first connecting ring 2 and the second connecting ring 3 to both ends of the tube body 1 by threading, it is convenient to assemble and disassemble the first connecting ring 2 and the second connecting ring 3 from the tube body 1, thereby facilitating the disassembly and replacement of the support rods 4. Both ends of the support rod 4 are provided with insertion posts 10. Multiple insertion holes 12 arranged in a circular array are provided on the opposite side of the first connecting ring 2 and the second connecting ring 3. An annular groove 11 is provided on the opposite side of the second connecting ring 3 and the first connecting ring 2. The diameter of the insertion post 10 is equal to the diameter of the insertion hole 12, and the width of the annular groove 11 is equal to the diameter of the insertion post 10. The diameter of the support rod 4 is larger than the diameter of the insertion post 10, and the length direction of the support rod 4 is parallel to the length direction of the tube body 1. The surface of the support rod 4 is in contact with the surface of the tube body 1. During installation, the first connecting ring 10 is first inserted into the tube body 1 through the cooperation between the insertion post 10, the insertion hole 12, and the annular groove 11. 2. After fixing the support rod 4 to the tube body 1, insert the pin 10 at one end of the support rod 4 into the insertion hole 12 of the first connecting ring 2 in sequence. Then connect the second connecting ring 3 to the tube body 1, so that the pin 10 of each support rod 4 is in the annular groove 11 of the second connecting ring 3. Finally, tighten the second connecting ring 3 and adjust the position of each support rod 4 so that the second connecting ring 3 cooperates with the first connecting ring 2 to squeeze and fix the support rod 4, so that the tube body 1 is wrapped inside the support rod 4. This can effectively prevent the tube body 1 from directly contacting external objects, thus playing a good protective role for the tube body 1 and greatly extending the service life of the tube body 1.
