[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use: 1. An anti-deformation mechanism is provided. Through the cooperation of the concave strip and the block, it is convenient to limit and socket the inner lining sleeve outside the insulating sleeve, ensuring the stability of the inner lining sleeve. Then, the backing plate is clamped and positioned through the limiting groove, facilitating the fixation of the U-shaped plate, the arc-shaped plate, and the top block between the inner lining sleeve and the insulating sleeve. Through the cooperation of the groove and the convex plate, the arc-shaped plate is further limited to prevent the arc-shaped plate from shifting; In addition, through the cooperation of the backing plate, the U-shaped plate, and the arc-shaped plate, after the cable is squeezed and bent, it can quickly rebound and reset, and push the top block to always keep in contact with the inner wall of the inner lining sleeve, ensuring the supporting effect on the inner lining sleeve, facilitating the cable to return to its original state, increasing the adaptability, and preventing the cable from wrinkling and collapsing.

[0015] 2. A heat dissipation and adjustment mechanism is provided. The cable is coated with a flame-retardant layer to improve the flame-retardant effect of the cable. In case of a fire, the spread of the fire is slowed down, and the loss is reduced. Moreover, through the cooperation of the reinforcing wire, the positive spiral fine wire, and the reverse spiral fine wire, the flame-retardant layer is strengthened, improving the strength of the flame-retardant layer and preventing it from breaking, increasing the service life. In addition, because the positive spiral fine wire, the reinforcing wire, and the reverse spiral fine wire are all copper wires, heat can be evenly transmitted, preventing heat concentration and improving the heat resistance of the cable; In addition, the outer side of the flame-retardant layer is wound with a heat-conducting and waterproof tape to fill the gaps between the reverse spiral fine wires, while improving the waterproof performance of the cable, preventing water droplets from entering the cable interior. The corrosion-resistant and heat-resistant layer improves the corrosion-resistant and flame-resistant effects of the cable, and the wear-resistant sheath increases the wear resistance of the cable, reducing the loss and ensuring the service life; In addition, the heat dissipation port facilitates the transfer of the heat inside the cable to the outside. When the heat inside the cable is too high, the expansion airbag expands due to heat, pushing the support block and the push block upward, thereby bending and separating the two adjacent rubber plates, releasing the adhesion of the two rubber plates, opening the rectangular slot, facilitating the direct discharge of heat through the rectangular slot, increasing the exhaust efficiency, further improving the heat dissipation effect, enabling the cable to withstand higher temperatures. After the temperature drops, the expansion airbag contracts, driving the push block to reset, causing the rubber plates to lose support, and then through the extrusion of the limit sleeve, the two adjacent rubber plates are reset and adhered, sealing the rectangular slot again. Additionally, through the cooperation of the breathable cotton, it prevents dust from entering the inside of the heat dissipation port during the heat dissipation process.

[0016] 3. A heat dispersion mechanism is provided. Through the cooperation of the hollow tube and the flame-retardant rock wool, the voids inside the insulating sleeve are filled, facilitating the support of the three conductors and preventing the phenomenon of offset and dislocation. At the same time, the flame-retardant rock wool can improve the flame-retardant effect of the cable. In addition, through the connecting block and the reinforcing ribs inside the hollow tube, the hollow tube is supported, increasing the strength of the hollow tube, ensuring the effect of supporting the conductors. At the same time, through the cooperation of the carbon fiber and the graphite wire core, the heat conduction efficiency is improved. When the temperature inside the insulating sleeve rises, the heat is quickly transferred horizontally, thereby evenly dispersing the temperature inside the insulating sleeve, preventing heat concentration, improving the heat dissipation effect, and enhancing the high-temperature resistance effect of the cable.

[0017] In summary, the anti-deformation mechanism, the heat dissipation adjustment mechanism, and the heat dispersion mechanism cooperate with each other, improving the overall strength of the cable. When subjected to extrusion and bending, it can quickly rebound and reset, improving the adaptability. At the same time, it can disperse the heat, prevent heat concentration, and when the temperature inside the cable is too high, it can automatically enhance the heat dissipation efficiency, quickly reduce the temperature inside the cable, enabling the cable to withstand higher temperatures, improving the high-temperature resistance performance, reducing the loss, and increasing the service life.

The heat dissipation mechanism 5 includes a hollow tube 501, a connecting block 502, a reinforcing rib 503, carbon fiber 504, flame-retardant rock wool 505 and a graphite core 506; Hollow tubes 501 are clamped between every two adjacent conductors 1 inside the insulating sleeve 2. Connecting blocks 502 are equidistantly clamped on the inner wall of the hollow tube 501. For the convenience of limiting the conductor 1, there are three hollow tubes 501 in total, and the outer side of the hollow tube 501 is in contact with the outer side of the conductor 1. There are three connecting blocks 502 inside one hollow tube 501. The other end of the connecting block 502 is clamped with a reinforcing rib 503. And carbon fiber 504 is filled between every two adjacent connecting blocks 502 inside the hollow tube 501. Flame-retardant rock wool 505 is filled at both sides of the hollow tube 501 inside the insulating sleeve 2. A graphite core 506 is filled between the three conductors 1. For limiting the hollow tube 501, the outer side of the flame-retardant rock wool 505 is in contact with the outer side of the hollow tube 501 and the outer side of the conductor 1 respectively. The outer side of the graphite core 506 is in contact with the outer sides of the three conductors 1 respectively.

[0023] The working principle and usage process of the present invention are as follows: First, the insulating sleeve 2 is sleeved outside the conductor 1 to wrap the three conductors 1. Then, through the cooperation of the hollow tube 501 and the flame-retardant rock wool 505, the voids inside the insulating sleeve 2 are filled, so as to support the three conductors 1 and prevent the phenomenon of deviation and dislocation. At the same time, when a fire occurs, the flame-retardant rock wool 505 can slow down the spread of the flame and improve the flame-retardant effect of the cable. In addition, through the cooperation of the connecting block 502 and the reinforcing rib 503, the inside of the hollow tube 501 is filled and supported, increasing the strength of the hollow tube 501 while maintaining the bending effect of the hollow tube 501, thereby ensuring the supporting effect of the hollow tube 501 on the conductor 1. In addition, the hollow tube 501 is filled with carbon fiber 504, which cooperates with the graphite wire core 506 to transfer the heat dissipated by the conductor 1 together. Then, when the temperature inside the insulating sleeve 2 rises, the heat is quickly and evenly transferred, forcing the temperature inside the insulating sleeve 2 to be evenly dispersed, preventing heat concentration and local overheating of the cable, improving the heat dissipation effect and reducing the loss; Next, the inner lining sleeve 301 is sleeved outside the insulating sleeve 2. Then, through the cooperation of the concave strip 302 and the clamping block 303, the inner lining sleeve 301 is limited, fixing the position of the inner lining sleeve 301 and preventing the inner lining sleeve 301 from deflecting. Then, through the limiting groove 304, it is convenient to clamp and position the backing plate 305. As a result, the backing plate 305, together with the U-shaped plate 306, the arc-shaped plate 307 and the top block 308, is fixed between the inner lining sleeve 301 and the insulating sleeve 2. At the same time, through the cooperation of the groove 309 and the convex plate 310, the U-shaped plate 306, the arc-shaped plate 307 and the top block 308 are further limited, improving the stability of the U-shaped plate 306 and the arc-shaped plate 307 and preventing the phenomenon of deflection. Thus, when the cable is squeezed or bent, the backing plate 305 pushes the U-shaped plate 306 and the arc-shaped plate 307 to bend, ensuring the bending effect. And after being squeezed and bent, according to the elasticity of the U-shaped plate 306 and the arc-shaped plate 307, it quickly rebounds and resets. And during the rebounding process, the arc-shaped plate 307 pushes the top block 308 to always keep in contact with the inner wall of the inner lining sleeve 301 to support the inner lining sleeve 301 and prevent the cable from wrinkling and collapsing, improving the adaptability; Next, the cable is coated with a flame retardant layer 402 to improve the flame retardant effect of the cable. Thus, in case of a fire, the spread of the fire can be slowed down, providing sufficient time for people to extinguish the fire, reducing losses. And the flame retardant layer 402 is reinforced and filled with reinforcing wires 403 to improve the strength of the flame retardant layer 402. Then, the positive spiral filaments 401 and the reverse spiral filaments 404 cooperate to wind and reinforce the flame retardant layer 402, forming a framework on the outer side and the inner wall of the flame retardant layer 402, further enhancing the strength of the flame retardant layer 402, preventing the occurrence of fracture phenomena, and increasing the service life. In addition, since the positive spiral filaments 401, the reinforcing wires 403, and the reverse spiral filaments 404 are all copper wires, they can evenly transfer heat, prevent heat concentration, and improve the heat resistance performance of the cable; Next, a heat-conducting waterproof tape 405 is wound around the outer side of the flame retardant layer 402 to fill the gaps between the reverse spiral filaments 404. At the same time, the waterproof performance of the cable is improved, preventing water droplets from entering the interior of the cable and preventing the occurrence of electric leakage phenomena. A corrosion-resistant and heat-resistant layer 406 is coated on the outer side of the heat-conducting waterproof tape 405 to further improve the corrosion-resistant and flame-retardant effects of the cable and increase the service life of the cable. Then, a wear-resistant sheath 412 is coated on the outer side of the corrosion-resistant and heat-resistant layer 406 to improve the wear-resistant effect of the cable, reduce losses, and ensure the service life; Finally, in cooperation with the heat dissipation ports 410, the heat inside the cable is transferred to the outside. And when the heat inside the cable is too high, the expansion airbag 409 continuously expands due to heat, pushing the support block 415 and the push block 416 to rise, forcing the push block 416 to push the adjacent two rubber plates 414 to bend and open, releasing the fit of the two rubber plates 414 and opening the rectangular groove 413, facilitating the heat to directly escape through the rectangular groove 413, further improving the heat dissipation effect. After the temperature drops, the expansion airbag 409 contracts, driving the push block 416 to reset, causing the rubber plates 414 to lose support. Then, through the extrusion of the limit sleeve 417, the rubber plates 414 are reset to restore the fit of the two rubber plates 414 and reseal the rectangular groove 413. In addition, in cooperation with the breathable cotton 411, it prevents dust from entering the interior of the heat dissipation ports 410 during the heat dissipation process, reducing the occurrence of blockage phenomena and ensuring the ventilation and heat dissipation effect.
