[0019] The following will be combined with the drawings Figures 1-6 The application will be further described in detail.

[0020] The application embodiment discloses a kind of inner sheath pipe structures for cable, including outer protective tube 1 and inner support pipe 3, both ends of inner support pipe 3 are connected with the both ends of outer protective tube 1 by setting connection mechanism and can be detached, and multiple baffle 4 are fixedly connected on the surface of inner support pipe 3, baffle 4 are all arranged along the radial direction of inner support pipe 3, and baffle 4 are annularly arrayed on the surface of inner support pipe 3, the side of baffle 4 away from inner support pipe 3 is attached to the inner surface of outer protective tube 1, and baffle 4 and inner support pipe 3 divide into multiple groups of wire slot space in outer protective tube 1.

[0021] In the embodiment, by setting baffle 4 and inner support pipe 3, the inside of outer protective tube 1 is divided into multiple groups of wire slot space, when wearing the cable, a group of wire slot space only allows accommodating a cable, so that the space inside outer protective tube 1 can be fully utilized, the cable is kept apart from each other, to ensure that each group of cable has enough space.​​

[0022] Further, the outer surface of the partition plate 4 is provided with air bags 5 on both sides, the inner supporting pipe 3 is hollow, and the air bags 5 are connected with the inner supporting pipe 3 through the connecting pipes 8.

[0023] Further, one side of the outer surface of the air bag 5 is installed on the surface of the partition plate 4 by coating adhesive.

[0024] In this embodiment, before the cable is inserted, the gas delivery end of the air pump is connected with the air valve port 6, the air pump is used to deliver gas into the inner supporting pipe 3, the gas enters the air bag 5 through the connecting pipe 8, and the air bag 5 is inflated. Then, one end of the cable to be installed is tied to the guide rod, the guide rod is used to pass through the slot space, thereby pulling one end of the cable to pass through the slot space. In this process, since the air bag 5 is soft, the air bag 5 wraps around the surface of the cable during movement of the cable, thereby protecting the cable and preventing the cable from being abraded. After all the cables are installed according to the above steps, the air pump is used to pump out the gas in the inner supporting pipe 3 and the air bag 5, thereby shrinking the air bag 5, and ensuring that the cable has a certain heat dissipation space.
