[0019] Reference Figure 1-5 As shown, the utility model provides a technical solution: an adjustable cable bridge, including a bridge body 1, a movable groove 20 is opened on the lower surface of the bridge body 1, and fixed plates 4 are arranged at both ends of the movable groove 20, and the upper ends of the fixed plates 4 are fixedly connected to the lower surface of the bridge body 1, a screw 5 is fixedly connected between the two fixed plates 4, and a plurality of sliding plates 6 are slidably connected to the surface of the screw 5, a partition 8 is fixedly connected to the upper end of the sliding plate 6, and fixing nuts 7 are arranged on both sides of the sliding plate 6, and the fixing nuts 7 are threadedly connected to the surface of the screw 5, and a fixing component is arranged at one end of the bridge body 1, and the position of the partition 8 on the bridge body 1 is adjusted by moving the position of the sliding plate 6 on the surface of the screw 5, so as to adapt to cables of different specifications and sizes and improve the utilization rate of the space in the bridge body 1, and when the position of the partition 8 is adjusted, the sliding plate 6 and the partition 8 are fixed by rotating the fixing nuts 7 at both ends of the sliding plate 6, so as to separate the cables in the bridge body 1 and avoid entanglement of a large number of cables.

[0020] Reference Figure 1 , Figure 2 and Figure 5As shown, in this embodiment: the fixing assembly includes two fixing frames 9 and a limiting strip 12, one side of the two fixing frames 9 is fixedly connected to the surface of the bridge body 1, and the inner wall of one of the fixing frames 9 is rotatably connected to a rotating frame 10, and the inner wall of the other fixing frame 9 is fixedly connected to a sliding rod 11, one end of the limiting strip 12 is threadedly connected to the surface of the rotating frame 10, and the other end of the limiting strip 12 is slidably connected to the surface of the sliding rod 11, and a plurality of sliding holes 13 are opened on the lower surface of the limiting strip 12, and the inner wall of the sliding hole 13 is fixedly connected to a limiting spring 14, and a limiting rod 15 is arranged at the lower end of the limiting spring 14, and the surface of the limiting rod 15 is slidably connected to the inner wall of the sliding hole 13, and the limiting strip 12 is slidably connected to the inner wall of the sliding hole 13 by rotating the rotating frame 10. 2 moves downward. When the limiting rod 15 below the limiting bar 12 presses the surface of the limiting cable, the limiting rod 15 will press the limiting spring 14 upward, and the reaction force will be generated by the deformation of the limiting spring 14, so as to fix the cable. Due to the multiple dense limiting rods 15 below the limiting bar 12, cables of different specifications and sizes can be fixed at the same time. Both ends of the lower surface of the bridge body 1 are provided with sliding grooves 16, and the inner wall of the sliding grooves 16 is slidably connected with multiple sliders 17. The upper ends of the sliders 17 are fixedly connected to the lower surface of the partition 8, and the cross-section of the sliders 17 is "T"-shaped. The two ends of the partition 8 are limited by the sliding grooves 16 and the sliders 17, so that when the position of the partition 8 is adjusted, the stability of the partition 8 when sliding can be enhanced.

[0021] Reference Figure 1 and Figure 3 As shown, specifically, a cover plate 2 is provided on the top of the bridge body 1, and slots 18 are provided on both sides of the cover plate 2, the inner wall of the slot 18 is slidably connected to a clamping strip 19, and the lower end of the clamping strip 19 is fixedly connected to the upper end of the bridge body 1, and the slot 18 and the clamping strip 19 can make the cover plate 2 open more conveniently and quickly, thereby improving the efficiency of the staff's inspection and installation of the cable, and a number of air holes 3 are provided on both sides of the bridge body 1, and the air holes 3 are evenly arranged and distributed. By setting the air holes 3, the air in the bridge body 1 can be more circulated, thereby improving the heat dissipation effect of the cable.

[0022] Working principle: When in use, the cover plate 2 can be pulled, and the cover plate 2 can be opened more conveniently and quickly through the card slot 18 and the card strip 19, and then the position of the sliding plate 6 on the surface of the screw rod 5 is moved to adjust the position of the partition 8 on the bridge body 1, so as to adapt to cables of different specifications and sizes and improve the utilization rate of the space in the bridge body 1. When the position of the partition 8 is adjusted, the sliding plate 6 and the partition 8 are fixed by rotating the fixing nuts 7 at both ends of the sliding plate 6, so as to separate the cables in the bridge body 1 to avoid entanglement of a large number of cables. After the cables are separated, the limit bar 12 is moved downward by rotating the rotating frame 10. When the limit rod 15 under the limit bar 12 squeezes the surface of the limit cable, the limit rod 15 will squeeze the limit spring 14 upward, and a reaction force is generated through the deformation of the limit spring 14, so as to fix the cable. Due to the multiple dense limit rods 15 under the limit bar 12, cables of different specifications and sizes can be fixed at the same time.
