DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Referring to Figures 1 to 2 , an embodiment provided by the utility model: a highly stable tray-type cable bridge, including a bridge floor 1. The bridge floor 1 is the basic component of the entire cable bridge and is made of a strong material to bear the weight of the cables and other hardware placed on it. A plurality of heat dissipation holes 2 are opened inside the bridge floor 1. The plurality of heat dissipation holes 2 opened inside enable the heat generated by the cables during operation to be effectively dissipated, thereby protecting the cables from overheating damage and extending their service life. A cover plate 3 is slidably connected to the top of the bridge floor 1. The cover plate 3 is designed to be slidably connected to the top of the bridge floor 1, providing a way to protect the cables and prevent damage to the cables caused by the external environment.

[0035] Referring to Figures 2 to 4 , a positioning component is provided at the bottom of the cover plate 3 to ensure that the cover plate 3 can be quickly and accurately positioned and fixed on the bridge floor 1. A first fixing plate 4 is slidably connected to the outside of the bridge floor 1. A second fixing plate 5 is rotatably connected to the top of the first fixing plate 4. The first fixing plate 4 and the second fixing plate 5 are the side support structures of the cable bridge, and they surround the outside of the bridge floor 1 and the cover plate 3 through a sliding connection. These two components cooperate to provide the necessary support and stability to ensure the overall structural strength of the bridge system. A positioning column 6 is slidably connected to the inside of the first fixing plate 4. The front end of the positioning column 6 is rotatably connected to a rotating plate 7. A first spring 8 is sleeved outside the rotating plate 7. One end of the first spring 8 is fixedly connected to the outside of the first fixing plate 4, and the other end of the first spring 8 is fixedly connected to the outside of the positioning column 6.

[0036] A fixing component is provided at the rear side inside the first fixing plate 4. The fixing component can fix the second fixing plate 5. A plurality of positioning grooves 9 are opened inside the front side of the bridge floor 1. The outside of the positioning column 6 is slidably connected to the inner wall of the positioning groove 9. The positioning column 6 slides inside the first fixing plate 4 and moves outward through the combination of the rotating plate 7 and the first spring 8. This design allows the positioning column 6 to be pulled out and inserted into the positioning groove 9 on the inner wall of the front side of the bridge floor 1 when needed, realizing the precise positioning and fixing of the position of the first fixing plate 4. The fixing component includes a fixing column 10. The outside of the fixing column 10 is fixedly connected to the inside of the second fixing plate 5. A bottom column 11 is fixedly connected to the top of the first fixing plate 4, which can firmly lock the second fixing plate 5 in place.

[0037] The bottom of the fixed column 10 is in contact with the top of the bottom column 11. A clamping plate 15 is rotatably connected to the top of the first fixing plate 4. The rear side of the second fixing plate 5 is squeezed downward. At this time, the fixed column 10 contacts and squeezes the bottom of the clamping plate 15. The outside of the clamping plate 15 is rotatably connected to the bottom of the second fixing plate 5. The clamping plate 15 rotates along with the card slot 16 and squeezes the limiting column 14 downward. A card slot 16 is provided on the outer side of the fixed column 10. The outside of the clamping plate 15 is engaged with the inner wall of the card slot 16. When the second fixing plate 5 is squeezed downward, the fixed column 10 contacts the bottom column 11 and pushes the clamping plate 15 to rotate, and finally the clamping plate 15 is engaged with the card slot 16 on the fixed column 10, thus ensuring the structural stability. A positioning component is provided at the bottom of the cover plate 3, and the positioning component can quickly position the cover plate 3.

[0038] Refer to Figures 5 to 7 , a cavity 12 is provided inside the first fixing plate 4. A second spring 13 is fixedly connected to the bottom of the cavity 12. The second spring 13 is compressed under force inside the cavity 12. The other end of the second spring 13 is fixedly connected to a limiting column 14. The cavity 12, the second spring 13 and the limiting column 14 provided inside the first fixing plate 4 form an auxiliary locking mechanism. The outside of the limiting column 14 is slidably connected to the inner wall of the cavity 12. The top of the limiting column 14 is in contact with the bottom of the clamping plate 15. When the clamping plate 15 is pushed downward by the second fixing plate 5, the limiting column 14 is under pressure and moves inside the cavity 12, while compressing the second spring 13, providing an additional locking force when the clamping plate 15 is in a horizontal state to ensure the stable fixation of the second fixing plate 5.

[0039] The positioning component includes a plurality of fixing blocks 17. The tops of the fixing blocks 17 are fixedly connected to the bottom of the cover plate 3. A plurality of fixing grooves 18 are provided on the front and rear sides of the top of the bridge floor 1. Align the fixing blocks 17 at the bottom with the fixing grooves 18 on the top of the bridge floor 1 and press the cover plate 3 downward. The outside of the fixing blocks 17 is engaged with the inner wall of the fixing grooves 18. The positioning component at the bottom of the cover plate 3 includes a plurality of fixing blocks 17, and these fixing blocks 17 are engaged with the fixing grooves 18 on the bridge floor 1. This design allows the cover plate 3 to be quickly positioned and fixed in place, improving the installation efficiency and ensuring the stability of the cover plate 3.

[0040] Working principle: First, place the bridge floor 1 in a suitable position. Then, place the cover plate 3 on top of the bridge floor 1. Align the fixing block 17 at the bottom with the fixing groove 18 at the top of the bridge floor 1 and press the cover plate 3 downward. At this time, the fixing block 17 and the fixing groove 18 are fixed. Then, surround the bridge floor 1 and the cover plate 3 with the first fixing plate 4 and the second fixing plate 5. After moving to a suitable position, rotate the rotating plate 7. When the rotating plate 7 rotates, it contacts the outside of the first fixing plate 4. While the rotating plate 7 rotates, it will pull the positioning post 6 to move outward, stretching the first spring 8. Then, align the positioning post 6 with the corresponding positioning groove 9 and rotate the rotating plate 7 again. At this time, the first spring 8 is no longer stressed and resets, pulling the positioning post 6 into the inside of the positioning groove 9, which can position the installation position of the first fixing plate 4.

[0041] Then, squeeze the rear side of the second fixing plate 5 downward. At this time, the fixing post 10 contacts the top of the bottom post 11 and squeezes the bottom of the clamping plate 15. At this time, the clamping plate 15 rotates along with the clamping groove 16 and squeezes the limiting post 14 downward. At the same time, the second spring 13 is compressed inside the cavity 12. When the clamping plate 15 is in a horizontal state, the outside of the clamping plate 15 is engaged with the clamping groove 16, which can fix the second fixing plate 5.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
