[0018] Preferred embodiment.

[0019] This embodiment provides an insulated cable protection tube, including a first inner tube 100 and a first outer tube 200. The inner wall of the first inner tube 100 is provided with a plurality of first protruding posts 120, the width of which is equal to the spacing between them. The outer wall of the first inner tube 100 is provided with a plurality of first T-slots 110. The inner wall of the first outer tube 200 is provided with a plurality of second T-slots 210. A plurality of first support plates 300 are provided between the first inner tube 100 and the first outer tube 200. One end of each support plate 300 near the first inner tube 100 is provided with a first connecting post 310, which matches the first T-slots 110. Another end of each support plate 300 near the first outer tube 200 is provided with a second connecting post 320, which matches the second T-slots 210.

[0020] Furthermore, the first support plate 300 has a first elastic part in the middle, the first elastic part includes a first arc plate 330 and a second arc plate 340, the first arc plate 330 and the second arc plate 340 are symmetrically arranged, one end of the first arc plate 330 and the second arc plate 340 is connected to the first connecting post 310, and the other end of the first arc plate 330 and the second arc plate 340 is connected to the second connecting post 320.

[0021] Furthermore, the outer wall of the first inner tube 100 is fitted with a first insulating layer 130, and the inner wall of the first outer tube 200 is fitted with a second insulating layer 220.

[0022] Furthermore, the first inner tube 100, the first outer tube 200, and the first support plate 300 form a plurality of first elastic cavities, and a first foam board 350 is provided in the first elastic cavity.

[0023] Furthermore, the first protruding post 120 has a first arc surface 121 at the end away from the first outer tube 200, and the first arc surface 121 is used to reduce friction with the cable.

[0024] Working Principle: The cable is threaded through the first inner tube 100. The first protruding post 120 supports the cable and reduces the contact area with the cable, thus reducing friction and making it easier for the cable to pass through the inner tube 100. The first arc surface 121 further enhances convenience, facilitating cable passage. The first inner tube 100 and the first outer tube 200 are connected by the first support plate 300, forming the first elastic cavity, which supports and accommodates the first foam board 350. The first foam board 350 not only has good insulation but also provides elasticity. When the first outer tube 200 is impacted and compressed inwards, the first foam board 350 also compresses, providing support and cushioning against the compression. Furthermore, the first elastic portion can withstand significant pressure through the deformation of the first arc plate 330 and the second arc plate 340, ensuring that the first outer tube 200 does not easily break, thus increasing the structural strength of the cable protection tube. The first insulating layer 130 and the second insulating layer 220 are made of rubber and have a thickness of 1-2 mm, which can further provide good insulation.

[0025] It is worth mentioning that the technical features such as the insulating layer involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0026] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
