This tubing is widely used in industries such as power, communications, petroleum, and chemicals, particularly in harsh environments or where high safety requirements are required.

[0003] For example, Chinese patent number CN218300824U discloses a pressure-resistant cable protection tube. This utility model improves the pressure resistance of the protection tube by providing multiple springs. However, the springs age and become brittle after long-term use, thereby reducing the pressure resistance of the springs and causing the pressure resistance of the protection tube to deteriorate. Therefore, a CMBWP reinforced cable protection tube is proposed to address the above-mentioned problem. Utility Model Content

[0011] Furthermore, opposite sides of the six telescopic rods are connected to the outside of the inner protective tube, and sides of the six telescopic rods away from the inner protective tube are connected to the inner wall of the connecting tube.

[0012] Furthermore, the number of the compression springs is six, the six telescopic rods are distributed and pass through the six compression springs, the six compression springs are all located between the inner protective tube and the connecting tube, and the connecting tube and the inner protective tube are connected through the compression springs.

The first pressure-resistant layer 401 is fixedly installed inside the outer protective tube 1. By setting the first pressure-resistant layer 401, the first pressure-resistant layer 401 is a glass fiber layer. The glass fiber layer has high strength and pressure resistance, which protects the outer protective tube 1 and further enhances the pressure resistance of the outer protective tube 1. The inner wall of the first pressure-resistant layer 401 is provided with a second pressure-resistant layer 402. The second pressure-resistant layer 402 is a metal woven mesh with metal filaments longitudinally extending from the outer protective tube 1. The mesh is woven horizontally and staggered to further disperse the pressure and has good pressure resistance. A rubber pad 403 is fixedly installed on the outer wall of the connecting pipe 2, and a sponge block 404 is provided between the rubber pad 403 and the second pressure-resistant layer 402, which can not only prevent the wear of the connecting pipe 2 but also further improve the buffering pressure resistance. The outside of the inner protective tube 3 is fixedly connected with a telescopic rod 405, and the outside of the telescopic rod 405 is sleeved with a pressure-resistant spring 406.

[0023] During implementation, follow these steps:

[0024] 1) First, insert the cables into the inner protective tube 3 one by one, and collect the cables in the inner protective tube 3;

[0025] 2) Then, the cable body 1 is double protected by the connecting tube 2 and the outer protective tube 1;

[0026] 3) When the outer protective tube 1 is under pressure, the first pressure-resistant layer 401 and the second pressure-resistant layer 402 can enhance the pressure resistance and protect the connecting tube 2 through the rubber pad 403;

[0027] 4) Finally, when the inner protective tube 3 is under pressure, the pressure is further dispersed by squeezing the telescopic rod 405 and the compression spring 406 to achieve a good compression resistance effect.

By providing a telescopic rod 405, when the inner protective tube 3 is under heavy pressure, the purpose of dispersing the pressure is achieved by squeezing the telescopic rod 405 and the pressure-resistant spring 406.

[0029] In addition, when in use, the cables are first inserted into the inner protective tube 3 in sequence, the cables are gathered and stored by the inner protective tube 3, and then the cable body 1 is doubly protected by the connecting tube 2 and the outer protective tube 1. When the outer protective tube 1 is under pressure, the first pressure-resistant layer 401 and the second pressure-resistant layer 402 can enhance the pressure resistance and protect the connecting tube 2 through the rubber pad 403.
