[0018] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

The slide rails 14 are slidably connected in the slide rail groove 20. A screw sleeve 17 is provided in the middle position of the upper cover 13. The screw sleeve 17 is threadedly connected to a screw rod 21. The bottom end of the screw rod 21 is rotatably connected to a hanging plate 15. Guide rods 16 are connected on both sides of the hanging plate 15. The guide rods 16 are connected to the upper cover 13. The middle of the bottom surface of the hanging plate 15 is connected to a hanging rod 10. The bottom end surface of the hanging rod 10 is connected to the upper support plate 8. The top of the screw rod 21 is connected to an adjusting wheel 18. A dust cover 19 is provided on the upper surface of the upper cover 13 at the position where the screw 21 is set.

[0021] The outer fireproof layer 2 is a ceramic silicone rubber layer. The outer fireproof layer 2 is converted into a ceramic body at high temperature to effectively block flames.

[0022] The corrosion-resistant layer 3 is a polytetrafluoroethylene layer, which prevents the inner layer from being corroded by moisture and rain.

[0023] The inner fireproof layer 4 is a composite metal oxide coating, which is a mixture of hydrated metal oxides, magnesium hydroxide and aluminum hydroxide. Under high temperature, the hydroxides in the inner fireproof layer 4 decompose into metal oxides, which cannot burn and block flames.

[0024] The slide rail groove 20 is in a convex shape and cooperates with the slide rail 14 of the upper cover 13 to achieve the sliding of the upper cover 13.

[0025] The top end of the guide rod 16 is connected with an anti-drop cap 22 so that the hanging plate 15 has the maximum descending height.

[0026] The two side edges of the lower supporting plate 5 and the upper supporting plate 8 are bent toward the opposite plates, so that the cables are gathered inside the upper supporting plate 8 and the lower supporting plate 5 .

[0027] The upper surface of the lower support plate 5 is provided with an upper convex positioning tooth 7 extending along the length direction, and the lower surface of the upper support plate 8 is provided with a lower convex positioning tooth 9 corresponding to the upper convex positioning tooth 7. The upper convex positioning tooth 7 and the lower convex positioning tooth 9 separate and position the cables, and the bottom of the cable is supported by the support plate 6, which is beneficial to the heat dissipation of the cable.

[0028] During use, the cable is placed on the support plate 6 between the upper convex positioning teeth 7 and the lower convex positioning teeth 9, and is dispersed from each other. The bottom of the cable is supported by the support plate 6 at intervals. The cable dissipates heat well in the bridge body 1. By adjusting the screw 21, the upper support plate 8 is lowered to make the upper convex positioning teeth 7 and the lower convex positioning teeth 9 docked to position the cable. A fireproof layer is provided on the inner and outer sides of the bridge body 1 to improve the fire resistance. The top two sides of the bridge body 1 are fixed to the building by connecting parts through the fixing holes 12.
