[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] Example 1: Reference Figure 1-Figure 2 A high-temperature resistant composite steel wire hose comprises: a tube body 1 and a PET composite film 2, wherein the side wall of the tube body 1 is covered with the PET composite film 2, and the thickness of the PET composite film 2 is 15-50 μm.

[0022] The principles and beneficial effects of the above scheme are:

[0023] After the side wall of the tube body 1 is coated with the PET composite film 2, it has excellent high-temperature heat shrinkage properties. The PET composite film 2 has an excellent shrinkage effect in a working environment with a temperature of up to about 200°C. Therefore, the higher the temperature, the tighter the wrapping, which can prevent the resin fluid transported in the tube body 1 from leaking. At the same time, it can ensure that the air outside the tube body 1 will not enter the inside of the tube body 1 through the cracks, thereby ensuring that the fluid resin will not be mixed with bubbles, and ensuring its physical properties after curing. The thickness of the composite film is 15-50μm, so it is very convenient to use the PET material used in pipeline manufacturing to coat the tube body 1, and greatly extend the service life of the pipeline structure and significantly reduce the manufacturing cost.

[0024] Example 2: Reference Figure 1-Figure 2 The tube body 1 includes a PVC tube, and a solenoid 4 is provided on the side wall of the PVC tube.

[0025] The principles and beneficial effects of the above scheme are:

[0026] After the solenoid 4 is provided on the side wall of the PVC tube, the tube body 1 has excellent bending ability.

[0027] Example 3: Reference Figure 1-Figure 2 One side of the solenoid 4 is placed outside the side wall of the PVC tube, and the other side of the solenoid 4 is arranged coplanar with the inner wall of the PVC tube.

[0028] The principles and beneficial effects of the above scheme are:

[0029] One side of the solenoid 4 is placed outside the side wall of the PVC tube. The solenoid 4 can serve as a heat dissipation structure to effectively dissipate the heat in the tube body 1. The other side of the solenoid 4 is coplanar with the inner wall of the PVC tube and will not affect the structure's guidance of the resin fluid.

[0030] Example 4: Reference Figure 1-Figure 2 A spiral cavity is provided in the solenoid 4 .

[0031] The principles and beneficial effects of the above scheme are:

[0032] The arrangement of the spiral cavity not only further ensures that the bending ability of the tube body 1 remains unchanged, but also reduces the weight of the entire structure and further reduces the manufacturing cost.

[0033] Example 5: Reference Figure 1-Figure 2 A spiral steel wire is inserted into the spiral cavity.

[0034] The principles and beneficial effects of the above scheme are:

[0035] A spiral steel wire is inserted into the spiral cavity to increase the strength of the tube body 1.

[0036] Example 6: Reference Figure 1-Figure 2The end of the solenoid 4 is arranged coplanar with the end of the PVC tube.

[0037] The principles and beneficial effects of the above scheme are:

[0038] The end of the solenoid 4 is arranged coplanar with the end of the PVC tube, which can further ensure the overall strength of the tube body 1.

[0039] Example 7: Reference Figure 1-Figure 2 The end of the PVC tube is connected to one side of the end ring 3.

[0040] The principles and beneficial effects of the above scheme are:

[0041] The end ring 3 can protect the end of the pipe body 1, so when the pipe body 1 is connected to other equipment, the end of the pipe body 1 can be prevented from cracking.

[0042] Example 8: Reference Figure 1-Figure 2 The end ring 3 is provided with a rounded corner on the side away from the PVC tube.

[0043] The principles and beneficial effects of the above scheme are:

[0044] The rounded corners on the end ring 3 can prevent the end of the tube body 1 from having a sharp structure, thereby reducing the possibility of damage after collision with other objects.

[0045] Example 9: Reference Figure 1-Figure 2 The side wall of the PVC tube is covered with a PET composite film 2.

[0046] The side wall of the solenoid 4 is covered with a PET composite film 2 .

[0047] The principles and beneficial effects of the above scheme are:

[0048] The PET composite film 2 covers the side wall of the PVC tube and the side wall of the solenoid 4 respectively, ensuring the covering effect of the composite film on the entire tube body 1.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
