[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-5 A combined ladder-type cable tray includes a cable tray side plate 1, a connecting component inside the cable tray side plate 1, an installation component inside the cable tray side plate 1, a ladder-type crossbeam 13 on the top of the cable tray side plate 1 via the installation component, the ladder-type crossbeam 13 overlapping with the cable tray side plate 1, a lower clamping block 14 fixedly installed on the top of the ladder-type crossbeam 13, an adjusting component on the top of the ladder-type crossbeam 13, a moving plate 18 on the top of the ladder-type crossbeam 13 via the adjusting component, an elastic component at the bottom of the moving plate 18, and an upper clamping block 22 at the bottom of the moving plate 18 via the elastic component. This combined ladder-type cable tray allows for disassembly and assembly of the cable tray side plate 1 and the ladder-type crossbeam 13 during transportation, reducing the footprint of each component and increasing transport capacity. During use, the installation component allows for assembly between the cable tray side plate 1 and the ladder-type crossbeam 13, and the connecting component allows for assembly between two cable tray side plates 1, eliminating the need for numerous bolts, simplifying operation, and enabling faster assembly of the ladder-type cable tray.

[0024] according to Figure 1 and Figure 2As shown, the connecting assembly includes a first through hole 2 penetrating inside the cable tray side plate 1. Multiple first insert rods 3 are inserted into the first through hole 2, and these first insert rods 3 are symmetrically distributed. The first insert rods 3 are adapted to the first through hole 2. A connecting plate 4 is fixedly installed on the surface of the first insert rod 3, and the connecting plate 4 overlaps with the cable tray side plate 1. A first receiving groove 5 is formed on the surface of the first insert rod 3. A first spring 6 is fixedly installed on the inner wall of the first receiving groove 5. A first limiting block 7 is fixedly installed on the surface of the first spring 6. The first limiting block 7 is slidably connected to the first receiving groove 5 and overlaps with the cable tray side plate 1. The first insertion rod 3 on the connecting plate 4 is inserted into the first through hole 2 on the two cable tray side plates 1. During the insertion process, the inclined surface of the first limiting block 7 is squeezed, so that the first limiting block 7 enters the first storage groove 5, and the first spring 6 is compressed. When the connecting plate 4 contacts the cable tray side plate 1, the force generated by the compression of the first spring 6 causes the first limiting block 7 to move away from the first storage groove 5, so that the first limiting block 7 is partially moved out of the first storage groove 5. The first limiting block 7 will contact the cable tray side plate 1, so that the first limiting block 7 is limited, which facilitates the fixation between the two cable tray side plates 1.

[0025] according to Figure 3 and Figure 4 As shown, the installation assembly includes a second through hole 8 extending through the bottom of the cable tray side plate 1. Multiple second rods 9 are inserted into the second through hole 8, arranged symmetrically. The second rods 9 are adapted to the second through hole 8 and are fixedly connected to the ladder-type crossbeam 13. A second storage groove 10 is formed on the surface of the second rod 9. A second spring 11 is fixedly installed on the inner wall of the second storage groove 10. A second limiting block 12 is fixedly installed on the surface of the second spring 11. The second limiting block 12 is slidably connected to the second storage groove 10 and overlaps with the cable tray side plate 1. The second rod 9 below the ladder-type crossbeam 13 is inserted through the second through hole. Insert the second through hole 8 into the upper part of the second through hole 8. During the insertion process, the inclined surface of the second limiting block 12 will be squeezed, so that the second limiting block 12 enters the second storage groove 10 and the second spring 11 is compressed. When the bottom of the ladder beam 13 contacts the cable tray side plate 1, the reverse force generated by the compression of the second spring 11 causes the second limiting block 12 to move away from the second storage groove 10, so that the second limiting block 12 is partially moved out of the second storage groove 10. At this time, the second limiting block 12 will contact the bottom of the cable tray side plate 1, so that the second limiting block 12 completes the limiting, thereby facilitating the fixation between the cable tray side plate 1 and the ladder beam 13.

[0026] according to Figure 5As shown, the adjustment component includes a support frame 15 fixedly installed on the top of the ladder beam 13. An adjustment rod 16 is threadedly connected inside the support frame 15. The adjustment rod 16 is rotatably connected to the moving plate 18, and the moving plate 18 is slidably connected to the support frame 15. A knob 17 is fixedly installed on the top of the adjustment rod 16. The elastic component includes a fixing sleeve 19 fixedly installed on the bottom of the moving plate 18. A third spring 20 is fixedly installed on the top of the inner wall of the fixing sleeve 19. A fixing post 21 is fixedly installed on the bottom of the third spring 20. The fixing post 21 is fixedly connected to the upper clamping block 22 and slidably connected to the fixing sleeve 19. The adjustment component allows the moving plate 18, the elastic component, and the upper clamping block 22 to move downwards to clamp the cable, reducing the risk of cable shaking or displacement during operation. Furthermore, the elastic component allows for adjustment of different applicable forces according to the cable size, facilitating the clamping and fixing of cables of different sizes.

[0027] In use: Insert the second insert 9 below the ladder beam 13 into the second through hole 8 from above. During insertion, the inclined surface of the second limiting block 12 will be squeezed, causing the second limiting block 12 to enter the second storage groove 10, thus compressing the second spring 11. When the bottom of the ladder beam 13 contacts the cable tray side plate 1, the reverse force generated by the compression of the second spring 11 causes the second limiting block 12 to move away from the second storage groove 10, causing the second limiting block 12 to partially move out of the second storage groove 10. At this time, the second limiting block 12 will contact the bottom of the cable tray side plate 1, completing the assembly of the cable tray side plate 1 and the ladder beam 13. When assembling two cable trays, align the sides of the two cable tray side plates 1 and insert the first insert 3 on the connecting plate 4 into the first through hole 2 on the two cable tray side plates 1. During insertion, the inclined surface of the first limiting block 7 will be squeezed. The compression causes the first limiting block 7 to enter the first storage groove 5, compressing the first spring 6. When the connecting plate 4 contacts the cable tray side plate 1, the force generated by the compression of the first spring 6 causes the first limiting block 7 to move away from the first storage groove 5, partially moving the first limiting block 7 out of the first storage groove 5. The first limiting block 7 then contacts the cable tray side plate 1, thus assembling the two cable trays. The cable is placed on the lower clamping block 14, and the knob 17 is rotated, causing the adjusting rod 16 to rotate and move downwards. This causes the moving plate 18 to move downwards along the support frame 15, causing the fixing sleeve 19, the third spring 20, the fixing post 21, and the upper clamping block 22 to move downwards, making the upper clamping block 22 contact the cable. The fixing post 21 and the upper clamping block 22 stop moving downwards, while the moving plate 18 and the fixing sleeve 19 continue to move downwards, compressing the third spring 20 until the cable is fixed.
