[0008] The bottom of the protective cover is fixedly connected to two first fixing plates. Each first fixing plate has a first sliding rod slidably connected to one side. Each first sliding rod has a snap-fit ​​post fixedly connected to one end. One end of each snap-fit ​​post is slidably connected to the corresponding side inside the cable tray body. Each snap-fit ​​post is adapted to a corresponding snap-fit ​​hole. The other end of each first sliding rod is fixedly connected to a moving rod. Each moving rod has a moving groove on one side. Each moving groove is movably connected to a corresponding actuating post.

[0009] As a further description of the above technical solution:

[0010] Each of the first sliding rods is movably provided with a first spring, one end of each first spring is fixedly connected to one side of the corresponding snap-fit ​​post, and the other end is fixedly connected to one side of the corresponding first fixing plate.

[0011] As a further description of the above technical solution:

[0012] The snap-fit ​​assembly includes a second sliding rod that slides through and is slidably connected to one side of the second fixed plate, and a pawl is fixedly connected to one end of the second sliding rod.

[0013] As a further description of the above technical solution:

[0014] A ratchet is fixedly connected to the rotating column, and the ratchet is adapted to the pawl.

A cable slot is fixedly connected to the upper surface of each connecting post. Multiple fixing posts are fixedly connected to the side of the cable tray body away from each other. A lifting ring is fixedly connected to the upper surface of each fixing post.

[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with existing technologies, this knob-type reverse-lock cable tray, by setting up a rotating column, a rotating disk, a toggle column, a first fixed plate, a first sliding rod, a locking column, a first spring, and a moving rod, rotates the rotating column, which drives the rotating disk to rotate. The rotating disk drives two toggle columns to rotate, and the two toggle columns drive the corresponding first sliding rods to move through the moving rods. The two first sliding rods drive the corresponding locking columns to move and compress the corresponding first springs, causing the locking columns to disengage from the inside of the cable tray body. This facilitates the quick removal of the protective cover by the staff and improves the removal efficiency.

[0021] 2. Compared with existing technologies, this rotary reverse-lock cable tray, by setting up a second sliding rod, pawl, second spring, and ratchet, allows the rotating column to rotate, which in turn drives the ratchet to rotate. The ratchet, through the cooperation of the pawl, prevents the rotating column from reversing when the operator releases it, thus covering the protective cover. Then, pulling the second sliding rod causes the pawl to move, disengaging it from the ratchet. Under the elasticity of the two first springs, the two locking posts pass through the interior of the cable tray body and engage with the corresponding locking holes, which can quickly fix the protective cover and improve installation efficiency.

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.

[0031] Reference Figures 1 to 6 This utility model provides a knob-type reverse-lock cable tray: including a cable tray body 1, with multiple connecting rods 8 fixedly connected to the inner bottom of the cable tray body 1, multiple connecting posts 9 fixedly connected to the upper surface of each connecting rod 8, and a cable slot 10 fixedly connected to the upper surface of each connecting post 9, so that the cable can be inserted into the cable slot 10 for easy cable locking and fixing. Multiple fixing posts 11 are fixedly connected to the opposite side of the cable tray body 1, and a lifting ring 12 is fixedly connected to the upper surface of each fixing post 11, so that the cable tray body 1 can be easily lifted by the multiple lifting rings 12. Two connecting grooves 2 are opened on the upper surface of the cable tray body 1, and a locking plate 3 is movably connected inside the two connecting grooves 2. Multiple locking holes are opened on one side of each locking plate 3. A protective cover 4 is fixedly connected to the upper surface of each locking plate 3. Multiple rotating structures 5 are provided on the protective cover 4. Multiple second fixing plates 6 are fixedly connected to the upper surface of the protective cover 4, and a locking component 7 is provided on each second fixing plate 6.

[0032] To achieve rotation, the rotating structure 5 includes a rotating column 501 rotatably connected to the upper surface of the protective cover 4. A rotating column 502 is fixedly connected to the upper surface of the rotating column 501. A rotating disk 503 is fixedly connected to the bottom of the rotating column 501. Two actuating columns 504 are fixedly connected to the bottom of the rotating disk 503. Two first fixing plates 505 are fixedly connected to the bottom of the protective cover 4. A first sliding rod 506 is slidably connected to one side of each first fixing plate 505. A locking post 507 is fixedly connected to one end of each first sliding rod 506. One end of each locking post 507 is slidably connected to a corresponding side inside the cable tray body 1. Each locking post 507 is adapted to a corresponding locking hole. A first spring 508 is movably mounted on each first sliding rod 506. One end of each first spring 508 is connected to a corresponding locking hole. One side of the snap-fit ​​post 507 is fixedly connected, and the other end is fixedly connected to one side of the corresponding first fixed plate 505. The other end of each first sliding rod 506 is fixedly connected to a moving rod 509. Each moving rod 509 has a moving groove on one side. Each moving groove is movably connected to the corresponding actuating post 504. Rotating the rotating post 502 causes the rotating post 502 to drive the rotating disk 503 to rotate through the rotating post 501. The rotating disk 503 drives the two actuating posts 504 to rotate. The two actuating posts 504 drive the corresponding first sliding rod 506 to move through the moving rod 509. The two first sliding rods 506 drive the corresponding snap-fit ​​post 507 to move and compress the corresponding first spring 508, so that the snap-fit ​​post 507 is disengaged from the inside of the cable tray body 1. This makes it convenient for workers to quickly remove the protective cover 4 and improves the removal efficiency of workers.

[0033] To achieve the snap-fit ​​purpose, the snap-fit ​​assembly 7 includes a second sliding rod 701 that is slidably connected through one side of the second fixed plate 6. A pawl 702 is fixedly connected to one end of the second sliding rod 701. A second spring 703 is movably mounted on the second sliding rod 701. One end of the second spring 703 is fixedly connected to one side of the second fixed plate 6, and the other end is fixedly connected to one side of the pawl 702. A ratchet 704 is fixedly connected to the rotating column 501. The ratchet 704 is adapted to the pawl 702. When the rotating column 501 rotates, the pawl 702 rotates... The column 501 drives the ratchet 704 to rotate. The ratchet 704, through the cooperation of the pawl 702, prevents the rotating column 501 from reversing when the operator releases the rotating column 502, thus covering the protective cover 4. Then, the second sliding rod 701 is pulled, which drives the pawl 702 to move, causing the pawl 702 to disengage from the ratchet 704. Under the elasticity of the two first springs 508, the two locking posts 507 pass through the interior of the cable tray body 1 and are locked into the corresponding locking holes, which can quickly fix the protective cover 4 and improve installation efficiency.

[0034] Working principle: Rotating the rotating column 502 causes the rotating disk 503 to rotate via the rotating column 501. The rotating disk 503 then rotates the two actuating columns 504. The two actuating columns 504 move their corresponding first sliding rods 506 via the moving rod 509. The two first sliding rods 506 move their corresponding locking columns 507 and compress their corresponding first springs 508, causing the locking columns 507 to disengage from the inside of the cable tray body 1. This facilitates quick removal of the protective cover 4 by workers and improves removal efficiency. When the rotating column 502 rotates... When rotating, the rotating column 501 drives the ratchet 704 to rotate. The ratchet 704, through the cooperation of the pawl 702, prevents the rotating column 501 from reversing when the operator releases the rotating column 502, thus covering the protective cover 4. Then, the second sliding rod 701 is pulled, which drives the pawl 702 to move, causing the pawl 702 to disengage from the ratchet 704. Under the elasticity of the two first springs 508, the two locking posts 507 pass through the interior of the cable tray body 1 and are locked into the corresponding locking holes, which can quickly fix the protective cover 4 and improve installation efficiency.
