[0037] Embodiment 1, the following further elaborates on this application in conjunction with Figure 1 FIG. 6.

[0038] The embodiment of this application discloses a core layer micro-porous foaming PVC cable protection tube, which includes an outer protection tube 10. Four sliding grooves 15 are circumferentially and spacedly arranged inside the outer protection tube 10. The cross partition board 30 is detachably inserted into the four sliding grooves 15 and is slidably connected with the four sliding grooves 15. The ends of the four cross partition boards 30 are slidably connected with the inner wall of the outer protection tube 10. The limiting plate 31 is arranged in a "V" shape, and the tin foil coating 32 is sleeved on the outside of the limiting plate 31 and is movably connected with the limiting plate 31.

[0039] Please refer to Figure 3 , limiting grooves 13 are symmetrically arranged at both ends of the outer protection tube 10. A T-shaped plate 20 is slidably connected inside the limiting grooves 13, and a bolt passes through the outer protection tube 10 and extends to the outside of the T-shaped plate 20, and the T-shaped plate 20 is threadedly fixed on the outside of the outer protection tube 10, so that the outer protection tube 10 and the T-shaped plate 20 can be detachably used.

[0040] And a telescopic rod 21 is fixedly welded to the inner wall of the T-shaped plate 20. A spring 22 is sleeved on the outside of the telescopic rod 21 and is movably connected with the spring 22. One end of the spring 22 and the telescopic rod 21 is fixedly welded to the inner wall of the T-shaped plate 20, and an arc-shaped pressing plate 23 is fixedly welded to one end of the spring 22 and the telescopic rod 21.

[0041] The cable body 14 inside the outer protective tube 10 can be protected by the outer protective tube 10, and the cable body 14 inside the outer protective tube 10 can be separated by the cross partition 30, so that the cable body 14 will not be damaged due to high heat when it is used later. The cross partition 30 can be slidably connected to the inner wall of the outer protective tube 10 through the slide groove 15. The cross partition 30 can change one space in the outer protective tube 10 into four independent spaces. When the cable body 14 is placed in the space separated by the cross partition 30 later, the arc pressure plate 23 is tightened by the spring 22 and the telescopic rod 21, so that the inner wall of the arc pressure plate 23 will press the cable body 14 against the space separated by the cross partition 30, and the tin foil coating 32 can be used to isolate the heat between the cable bodies 14 and the cable bodies 14 later, so that the cable will not be damaged due to the high temperature of the cable body 14 when it is used later.

[0042] Please refer to Figure 1-2 The anti-slip cover 11 is put on the outside of the outer protective tube 10, and the inner wall of the anti-slip cover 11 is embedded and fixed with the outer side of the outer protective tube 10. The anti-slip cover 11 can prevent the outer protective tube 10 from rotating and causing the cable to shake when the outer protective tube 10 is placed underground later. The material of the anti-slip cover 11 is set to soft silicone, so the silicone will generate friction with the ground when used later, so that the outer protective tube 10 will not roll when used.

[0043] Please refer to Figure 4-5 Three protrusions are fixedly provided on the outer side of the U-shaped limiter 33, and through grooves are opened on the outer sides of the tin foil coating 32, the limiter plate 31 and the cross partition 30. The protrusions on the outer side of the U-shaped limiter 33 pass through the tin foil coating 32, the limiter plate 31 and the through grooves on the outer side of the cross partition 30, so that the U-shaped limiter 33 is embedded and fixed with the tin foil coating 32, the limiter plate 31 and the cross partition 30.

[0044] The U-shaped limiter 33 can be used to limit the corner of the tin foil coating 32 at the corner of the limiter plate 31 and the cross partition 30, so that the corners of the tin foil coating 32, the limiter plate 31 and the cross partition 30 are in a horizontal line, and after the U-shaped limiter 33 is installed, the inner wall of the U-shaped limiter 33 will fit tightly with the outer side of the cable body 14.

[0045] After all parts are connected to the outer protective tube 10 , the foam glue 12 is injected into the remaining space of the outer protective tube 10 so that no space is left inside the outer protective tube 10 , thereby making the inside of the outer protective tube 10 have a certain degree of sealing.

[0046] Working principle and process of this utility model:

[0047] When in use, first slide the cross partition 30 into the interior of the slide groove 15, then wrap the tin foil coating 32 on the outside of the limit plate 31, and finally slide the two ends of the limit plate 31 into the interior of the two slide grooves 15 respectively, so that the limit plate 31 is limited on the outside of the cross partition 30. When the limit plate 31 is limited, the tin foil coating 32 will also be limited synchronously.

[0048] In addition, tin foil can provide electromagnetic shielding effect and effectively reduce electromagnetic interference. At the intersection of cables, different cables may carry different signals or currents, and these signals or currents may interfere with each other, resulting in signal quality degradation or current crosstalk. Using tin foil to wrap the intersection can form a shielding layer to block the interference of external electromagnetic fields on the signal and improve the reliability and stability of the signal.

[0049] After sliding the T-plate 20 into the limiting groove 13, the T-plate 20 is threadedly fixed to the outside of the outer protective tube 10 by bolts, and finally the cable body 14 is placed on the top of the tin foil coating 32, so that the outside of the U-shaped limiting piece 33 is in contact with the outside of the cable body 14. When the cable body 14 is in contact with the U-shaped limiting piece 33, the inner wall of the arc-shaped pressure plate 23 will also be in contact with the outside of the cable body 14. When the cable body 14 is larger, the spring 22 and the telescopic rod 21 will be tightened. When the telescopic rod 21 and the spring 22 are tightened, the force of the arc-shaped pressure plate 23 against the cable body 14 will also be greater.

[0050] Finally, the foam glue 12 is injected into the remaining space of the outer protective tube 10 so that no space is left inside the outer protective tube 10 , thereby making the inside of the outer protective tube 10 have a certain degree of sealing.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
