[0020] In the description of the present invention, it should be understood that if there are descriptions involving orientation, such as orientations or positional relationships indicated by up, down, front, back, left, and right, the orientation description may be based on the orientation or positional relationships shown in the drawings. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0021] In the description of the utility model, if there is a description of quantity, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of first or second, it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0023] like Figures 1 to 5As shown, the utility model discloses an impact-resistant fireproof high-performance cable sheath tube, including a cylindrical tube body 1, one end of the cylindrical tube body 1 is provided with an annular plug-in portion 4 extending outward, the outer diameter of the annular plug-in portion 4 is smaller than the outer diameter of the cylindrical tube body 1, the inner wall of the other end of the cylindrical tube body 1 is provided with an annular docking groove 5 adapted to the annular plug-in portion 4, the cylindrical tube body 1 includes an inner silicone fireproof layer 2 and an outer carbon fiber explosion-proof layer 3 coated on the outer periphery of the inner silicone fireproof layer 2, the inner silicone fireproof layer 2 and the outer carbon fiber explosion-proof layer 3 can be bonded together by a silicone adhesive, the cylindrical tube body 1 is surrounded by two semicircular side walls, and an arc clamp limit groove 6 is symmetrically provided at both ends of the outer periphery of the two semicircular side walls. The original cable sheath tubes all need to be put on the cable at one end before wiring, and then wired, and then the cable sheath tube is moved to the cable joint for fixed protection after wiring, which is not very convenient to install. The cylindrical tube body 1 of the utility model is enclosed by two semicircular side walls, so that when in use, the two semicircular side walls can be directly sleeved on the cable joint, and then fixed to the arc clamp limit groove 6 by two clamps to lock and fix it, so that installation and use are more convenient and quick, and the inner silicone fireproof layer 2 can play a better fireproof effect and ensure the use and installation performance, and the outer carbon fiber explosion-proof layer 3 is provided, which has high strength, light weight and better explosion-proof effect. The utility model also provides an annular plug-in part 4 and an annular docking groove 5 at both ends, so that two or more cable sheath tubes can be connected end to end for use as needed, meeting the use scenarios with different length requirements and improving versatility.

[0024] In the utility model, the impact-resistant and fire-proof high-performance cable sheath pipe also includes a limiting clamp (not shown in the figure), and the limiting clamp is two and is respectively installed in the arc-shaped clamp limiting groove 6 at both ends. The limiting clamp is a stainless steel clamp, which is fixed on the arc-shaped clamp limiting groove 6 to bind and lock its two semicircular side walls. It is easy to install and has low installation requirements. The sheath pipe can be fixed without using fire, and the cable structure will not be damaged, which has a higher safety factor.

[0025] The cable sheath tube of the utility model is fixed by a limit clamp, so that the two ends of the sheath tube are not in a closed state, which is conducive to heat dissipation. The existing sheath tube is generally fastened to the cable joint by fire or high temperature heating, so it will form a closed state, which will make its heat dissipation effect poor, easily cause energy accumulation, and cause safety hazards.

[0026] In the utility model, the inner wall of the outer carbon fiber explosion-proof layer 3 is also coated with a primer layer, which can improve the adhesion and further improve the bonding performance with other layers.

[0027] In some embodiments, an insulating layer 7 is further provided on the inner side of the inner silicone fireproof layer 2. The insulating layer 7 can further improve the protection capability of the cable joint and ensure safety.

[0028] In some embodiments, a buffer layer 8 is further provided between the inner silica gel fireproof layer 2 and the outer carbon fiber explosion-proof layer 3. The buffer layer 8 may be a glass fiber layer, which can improve the structural strength and buffer effect, and improve the impact resistance.

[0029] In some embodiments, a limiting structure is further provided at the joint of the two semicircular side walls, and the limiting structure includes a limiting protrusion provided on one semicircular side wall and a limiting groove provided on the other semicircular side wall. This can play a limiting role when the two semicircular side walls are butted together, prevent the misalignment phenomenon when the limiting clamp is bound, and make fixation more convenient.

[0030] In the utility model, the thickness of the outer carbon fiber explosion-proof layer 3 is 5-6 mm. The length of the cylindrical tube body 1 is 450-550 mm, which can meet general use requirements and can further increase the use length by connecting multiple tubes.

[0031] In the present invention, the outer diameter of the cylindrical tube body 1 is 120-140 mm.

[0032] The utility model has a simple structure, and the two semicircular side walls can be directly sleeved on the cable joint, and then the two clamps are fixed in the arc clamp limit groove 6 to lock and fix it, so that installation and use are more convenient and quick, and the inner silicone fireproof layer 2 is provided to have a better fireproof effect, and the usability and installation are guaranteed. The outer carbon fiber explosion-proof layer 3 is provided, which has high strength, light weight and better explosion-proof effect. An annular plug-in portion 4 and an annular docking groove 5 are respectively provided at both ends, so that two or more cable sheath tubes can be connected end to end according to needs and used to meet the use scenarios with different length requirements.

[0033] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
