[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this cable tray that can be quickly connected, after the triangular ends of the connecting hooks on both sides enter the inner cavity of the connecting hook respectively, the rotating rod and the semi-cylinder restricted by the spring are in an inclined state. When the triangular end enters the inner cavity, under the correction of the triangular end, the inclined semi-cylinder is pushed upright and fits with another semi-cylinder. At this time, after the semi-cylinders fit with each other, they rotate again to lock the two mutually-fitting connecting hooks, which makes the fixation of the cable trays on both sides.

[0022] 2. In this cable tray that can be quickly connected, when the pushing and pulling plate pushes the sliding rod, it will also drive the arc-shaped sliding plate to slide in the direction of both sides of the pushing and pulling assembly. At this time, under the restriction of the strip-shaped groove, the raised block inside the rotating ring will slide along the groove of the strip-shaped groove and gradually slide from the top strip-shaped groove to the side. At this time, the rotating ring will rotate an angle under the drive of the raised block, so that the upper regularizing plate fits with the lower regularizing plate to regularize the cables inside the cable tray.

[0023] 3. In the quickly connectable cable tray, by a worker pulling the pushing block outward, the pushing block drives the first connecting rod and the sliding block to slide to the right simultaneously. The sliding block drives the pulling rope to pull the rotating rod to rotate upward, making the two semi-cylinders divided and leveled up and down again. At this time, under the pulling of the pushing and pulling assembly on the sliding rod, the semi-cylinders and the connecting hooks on both sides slide away from each other. This enables the worker to disassemble the cable tray by only pulling the pushing block to one side during disassembly, which is convenient and fast. Description of the Drawings

[0038] As Figure 2As shown in the figure, sliding rails 12 are fixedly connected to both inner sides of the interlayer 111. Sliding blocks 121 are slidably connected to both sliding rails 12. A first connecting rod 13 is fixedly connected between the two sliding blocks 121. A pushing block 14 is fixedly connected to the middle end of the first connecting rod 13. The pushing block 14 penetrates through the outer wall of the top of the upper shell 11 of the bridge, and the pushing block 14 is slidably connected to the top of the upper shell 11 of the bridge. Lower regularizing plates 15 are fixedly connected to both sides of the bottom inner wall of the lower shell 1 of the bridge. A protective shell 16 is arranged at the middle position of the lower regularizing plates 15. The protective shell 16 is fixedly connected to the bottom inner wall of the lower shell 1 of the bridge. The pushing and pulling assembly 3 is arranged inside the protective shell 16.

[0039] As Figures 4-5 As shown in the figure, the disassembly and assembly component 2 includes a fixed column 21. The fixed column 21 is fixedly connected to both sides of the bottom inner wall of the lower shell 1 of the bridge. An arc-shaped groove 211 is formed on the outer wall of the fixed column 21. A sliding component 22 is arranged inside the fixed column 21. The sliding component 22 includes a sliding rod 221. The sliding rod 221 is slidably connected to the inside of the fixed column 21. A fixed disk 222 is fixedly connected to one end of the fixed column 21. The fixed disk 222 is located at one end of the fixed column 21. An arc-shaped sliding plate 223 is fixedly connected to the outer edge of the fixed disk 222. A strip-shaped groove 2231 is formed on the outer wall of the arc-shaped sliding plate 223. The arc-shaped sliding plate 223 fits with the arc-shaped groove 211. The arc-shaped sliding plate 223 is slidably connected to the arc-shaped groove 211. A plurality of rotating rings 23 are rotatably connected to the outer wall of the middle end of the fixed column 21. A raised block 231 is fixedly connected to the inner wall of the rotating ring 23. The diameter of the raised block 231 fits with the width of the strip-shaped groove 2231. An upper regularizing plate 24 is fixedly connected to the outer wall of the rotating ring 23. A semi-circular groove 241 is formed at the bottom of the upper regularizing plate 24. A semi-circular groove 241 is also formed at the top of the lower regularizing plate 15. The two semi-circular grooves 241 of the upper regularizing plate 24 and the lower regularizing plate 15 are in alignment.

[0040] As Figure 6 As shown in the figure, a connecting hook 25 is fixedly connected to one end of the sliding rod 221. An inner cavity 251 is formed inside the connecting hook 25. A strip-shaped hole 252 is formed on the outer wall of the connecting hook 25. A semi-cylindrical column 253 is rotatably connected inside the inner cavity 251. A rotating rod 254 is fixedly connected to the outer wall of the semi-cylindrical column 253. A pulling rope 122 is fixedly connected to the end of the rotating rod 254 away from the semi-cylindrical column 253. The pulling rope 122 passes through the bottom of the upper shell 11 of the bridge and enters the interlayer 111 at the end away from the rotating rod 254 and is fixedly connected to one end of the sliding block 121. Among them: a spring 255 is arranged inside the connecting hook 25. One end of the spring 255 is fixedly connected to the inner wall of the connecting hook 25. The end of the spring 255 away from the inner wall of the connecting hook 25 is fixedly connected to the rotating rod 254.

[0041] As Figures 7-8As shown in the figure, the push-pull assembly 3 includes a motor 31. The bottom of the motor 31 is fixedly connected to a fixing plate 311, and the fixing plate 311 is fixedly connected to the inner wall of the protective shell 16. The output end of the motor 31 is fixedly connected to a threaded rod 32. The outer wall of the threaded rod 32 is threadedly connected to an upper sliding ring 33 and a lower sliding ring 35. Among them: a transmission belt 321 is sleeved on the outer walls of the lower ends of the threaded rods 32 on both sides. The threads on the outer wall of the threaded rod 32 are two symmetric sections, and the two sections of threads on the threaded rod 32 are distributed in opposite directions. The outer walls on both sides of the upper sliding ring 33 and the lower sliding ring 35 are rotatably connected to second connecting rods 34. The second connecting rods 34 are provided with push-pull plates 36 at the ends far from the upper sliding ring 33 and the lower sliding ring 35. The second connecting rods 34 are rotatably connected to the push-pull plates 36 at the ends far from the upper sliding ring 33 and the lower sliding ring 35. The push-pull plates 36 are fixedly connected to the ends of the sliding rods 221 far from the connecting hooks 25.

[0042] It can be seen from this that when it is necessary to quickly connect the cable tray, as Figures 3-5 shown, after the staff aligns the two sections of the tray, the threaded rod 32 rotates under the drive of the motor 31. At the same time, under the drive of the threads in different directions at the upper and lower ends of the threaded rod 32, the upper sliding ring 33 and the lower sliding ring 35 slide in different directions. At this time, the upper sliding ring 33 slides upward, while the lower sliding ring 35 slides downward. At this time, the second connecting rods 34 will be driven by the upper sliding ring 33 and the lower sliding ring 35 to expand towards the push-pull plate 36, and at the same time push the push-pull plate 36 to expand outward. The two push-pull plates 36 on both sides will drive the connecting hooks 25 adjacent to the sliding rods 221 on both sides to approach each other;

[0043] As Figure 6 shown, after the triangular ends of the connecting hooks 25 on both sides enter the inner cavity 251 of the connecting hook 25 respectively, the rotating rod 254 and the semi-cylinder 253 restricted by the spring 255 are in an inclined state. When the triangular end enters the inner cavity 251, under the correction of the triangular end, the inclined semi-cylinder 253 is pushed straight and fits with another semi-cylinder 253. Then, under the action of the spring 255, it rotates back to its original position. At this time, after the semi-cylinders 253 fit with each other and rotate again, the two mutually-fitting connecting hooks 25 are locked, which also fixes the two sides of the tray;

[0044] At the same time, when the push-pull plate 36 pushes the sliding rod 221, it will also drive the arc-shaped sliding plate 223 to slide towards both sides of the push-pull assembly 3. At this time, under the restriction of the strip-shaped groove 2231, the convex block 231 inside the rotating ring 23 will slide along the groove of the strip-shaped groove 2231 and gradually slide from the top strip-shaped groove 2231 to the side. At this time, the rotating ring 23 will be driven by the convex block 231 to rotate 90 degrees, so that the upper regular plate 24 fits with the lower regular plate 15, and the cables inside the tray are regularized;

[0045] When it is necessary to disassemble the cable tray, such as Figures 1-2 shown, the staff pulls the push block 14 outward. At the same time, the push block 14 drives the first connecting rod 13 and the sliding block 121 to slide to the right together. The sliding block 121 drives the pull rope 122 to pull the rotating rod 254 to rotate upward, so that the two semi-cylinders 253 are divided up and down and level again. At this time, under the pulling of the push-pull assembly 3 on the sliding rod 221, the two side semi-cylinders 253 and the connecting hooks 25 slide away from each other to both sides. At the same time, the upper regularizing plate 24 is lifted again. At this time, the push block 14 is released. Under the action of the spring 255, the rotating rod 254 returns to its original position again. This enables the staff to disassemble the cable tray by only pulling the push block 14 to one side when disassembling the cable tray, which is convenient and fast.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
