[0030] 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 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.

[0031] Refer to Figures 1 to 3, an embodiment provided by the present utility model: a combined cable tray, including tray one 1 and tray two 2. Tray one 1 and tray two 2 are usually made of steel trays, which have the characteristics of high strength and good durability, and are suitable for heavy loads and harsh environments. A tray cover 3 is slidably connected to the top of tray one 1. The tray cover 3 can slide along the top of tray one 1 to be conveniently opened or closed when needed, facilitating the inspection and maintenance of the cables. The design of the sliding connection ensures the tight fit of the cover plate, preventing dust and other foreign objects from entering the inside of the tray. Connecting plates 4 are fixedly connected to both the front and rear sides of tray one 1. The connecting plates 4 are L-shaped. The design of the connecting plates 4 enables the firm connection of the sides of the two tray units and provides a certain supporting force at the bottom. A plurality of bolt nuts 5 are threadedly connected inside the connecting plates 4. The bolt nuts 5 ensure the tightness and stability of the connection. The threaded connection design simplifies the installation process and allows for later adjustment and maintenance. Two rotating plates one 6 are rotatably connected to the bottom of tray one 1. By adding the rotating plates one 6 to connect the bottoms of the two trays, the supporting force is increased. A torsion spring 9 is fixedly connected to the bottom of the rotating plate one 6. The torsion spring 9 provides a reverse acting force for rotation to complete the rotational engagement. A rotating handle 8 is fixedly connected to the bottom of the torsion spring 9. The rotating handle 8 is used to operate the torsion spring 9, enabling the user to conveniently adjust the rotational state of the subsequent structure. A rotating rod 10 is fixedly connected to the top of the rotating handle 8. Through the rotation and sliding of the rotating rod 10, the functions of connecting the rotating plate one 6 and tray two 2 are realized. A clamping bar 7 is fixedly connected to the top of the rotating rod 10. Fixation is achieved through the clamping of the clamping bar 7 to prevent detachment. A fixing component for fixing the cables is provided inside tray two 2.

[0032] Refer to Figure 3 , the inside of the torsion spring 9 is sleeved outside the rotating rod 10. One end of the torsion spring 9 is fixed on the rotating handle 8 through the sleeving. The rotating handle 8 drives the rotating rod 10 to rotate, and then drives the rotation of the clamping bar 7. The outside of the rotating rod 10 is in contact with the inside of the rotating plate one 6. The rotating rod 10 can rotate and slide inside the rotating plate one 6. The outside of the clamping bar 7 is clamped with the inner bottom end of tray two 2. Through the clamping of the clamping bar 7 and tray two 2, the fixation of the rotating plate one 6 and tray two 2 is completed.

[0033] Refer to Figure 4, the fixing component includes a cable base 11 and a cable top seat 12. The bottom of the cable base 11 is fixedly connected to the inner bottom end of the second bridge 2. Multiple arc grooves are formed in the middle of the cable base 11 to adapt to the outer contour of the cable and reduce friction. Slide rods 13 are fixedly connected to the left and right ends of the cable top seat 12. The outer parts of the two slide rods 13 are respectively slidably connected to the front and rear sides of the second bridge 2. The sliding of the slide rod 13 drives the cable top seat 12 to drop, and the cable is clamped and fixed with the cable base 11. Rotating rods 14 are rotatably connected to the inner parts of the front and rear sides of the second bridge 2. The rotation of the rotating rod 14 drives the rotation of the subsequent structure to control the slide rod 13. Ratchets 17 are fixedly connected to the outer parts of the adjacent sides of the two rotating rods 14. Pawls 16 are rotatably connected to the inner front and rear sides of the second bridge 2. The cooperation of the ratchet 17 and the pawl 16 restricts the reverse rotation of the rotating rod 14, thereby fixing the height of the slide rod 13. The outer parts of the two pawls 16 are engaged with the outer parts of the two ratchets 17. Rotating plates two 15 are fixedly connected to the outer parts of the two rotating rods 14. Extra space is provided inside the rotating plates two 15 to accommodate the movement of the inner slide rod 13. The inner parts of the two rotating plates two 15 are respectively in contact with the outer parts of the two slide rods 13.

[0034] Working principle: First, the staff aligns the first bridge 1 and the second bridge 2, and threads multiple bolts and nuts 5 through the connecting plates 4 on both sides for fixed connection. At this time, by rotating the two rotating plates one 6 to the bottom of the second bridge 2, and then rotating the rotating handle 8, align the clamping strip 7 with the card slot inside the second bridge 2 and slide it into the second bridge 2, then release the rotating handle 8. Through the rotational reaction force and pulling force of the torsion spring 9, the clamping strip 7 is driven to engage inside the second bridge 2. The two rotating plates one 6 connect the bottom of the first bridge 1 and the second bridge 2 to make them an integral whole, providing additional support force, reducing the risk of the interface breaking due to heavy weight, and improving the durability of the bridge.

[0035] Secondly, by rotating the two pawls 16 inside the second bridge 2, the cable top seat 12 is lifted to drive the two slide rods 13 to slide upward inside the second bridge 2. At this time, multiple cables are passed through the middle of the cable base 11 and the cable top seat 12. Rotate the pawl 16 to engage it with the ratchet 17, and then release the cable top seat 12. Due to the gravity of the cable top seat 12, it slides downward to drive one end of the two rotating plates two 15 to move, and then drives the rotating rod 14 to rotate. The rotation of the rotating rod 14 drives the ratchet 17 to rotate, and the engaged pawl 16 on the ratchet 17 restricts the reverse rotation of the ratchet 17 to form a limit fixation, thereby fixing the rotation angle of the slide rod 13 and achieving limit fixation of the cable top seat 12, so as to classify and clamp the internal cables, which can prevent the cables from rubbing against each other inside the bridge, thereby reducing wear, lowering the risk of cable breakage or insulation damage, and improving safety.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described 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 utility model shall be included within the protection scope of the present utility model.
