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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a ladder-type aluminum alloy cable tray that is easy to install, including a support plate 1. Support rods 2 are fixedly installed on the top left and right sides of the support plate 1. The ladder-type aluminum alloy cable tray body 3 is placed on the top of the support plate 1 between the two support rods 2. Since the provision of ladder-type aluminum alloy cable trays is common knowledge in the field, the specific structure and principle of the ladder-type aluminum alloy cable tray will not be described in detail in this application. Connecting grooves 4 are opened on the top left and right sides of the support plate 1, located below the ladder-type aluminum alloy cable tray body 3. A connecting block 5 is movably installed inside each of the two connecting grooves 4, with one end fixedly connected to the bottom of the ladder-type aluminum alloy cable tray body 3.

[0021] A rectangular block 6 is fixedly installed at the bottom of the support plate 1. A rectangular groove 7 is opened at the top of the rectangular block 6. A threaded rod 8 is movably installed between the left and right sides of the inner wall of the rectangular groove 7. A first bearing is fixedly installed on both the left and right sides of the inner wall of the rectangular groove 7. The threaded rod 8 is rotatably connected to the inner wall of the rectangular groove 7 through the first bearing. A traction block 9 is movably installed on both the left and right sides of the interior of the rectangular groove 7, with one end threadedly connected to the outer side of the threaded rod 8. The outer side of the threaded rod 8 is provided with two threads of equal length and opposite direction.

[0022] The bottom of the support plate 1 is provided with an installation groove 10 located between two connecting grooves 4. The top of each of the two traction blocks 9 is fixedly installed with a movable block 11 extending into the installation groove 10 and movably connected to the top wall of the installation groove 10. The left and right sides of the inner wall of the installation groove 10 are connected with through holes 12 opened on the support plate 1. The opposite sides of the two movable blocks 11 are fixedly installed with positioning blocks 13, one end of which extends into the two through holes 12 respectively. The opposite sides of the two connecting blocks 5 are provided with positioning grooves 14 located on the opposite sides of the two positioning blocks 13 respectively.

[0023] A rotating assembly 15 is movably mounted on the bottom left side of the rectangular block 6, extending into the rectangular groove 7 and fixedly connected to the outside of the threaded rod 8. The rotating assembly 15 includes a mounting shaft 151. A circular hole is opened on the bottom left side of the rectangular block 6, and a second bearing is fixedly mounted inside the circular hole. The mounting shaft 151 is rotatably connected to the rectangular block 6 through the second bearing. A drive bevel gear 152 is fixedly mounted on the top of the mounting shaft 151. A driven bevel gear 153 is fixedly mounted on the outside of the threaded rod 8, located on the left side of the left traction block 9 and meshing with the drive bevel gear 152 at one end. A handwheel 154 is fixedly mounted on the bottom of the mounting shaft 151.

[0024] Both traction blocks 9 have limiting grooves 16 at their bottoms. The left limiting groove 16 is located on the right side of the bottom of the left traction block 9, and the right limiting groove 16 is located on the left side of the bottom of the right traction block 9. A limiting component 17 is fixedly installed on the bottom of the rectangular block 6, extending into the rectangular groove 7 and fitting against the bottom of the two traction blocks 9. The limiting component 17 includes a mounting plate 171. Mounting plates 171 are fixedly installed on the left and right sides of the bottom of the rectangular block 6, respectively located below the two traction blocks 9. Sliding grooves 172 are provided on opposite sides of the two mounting plates 171. A movable plate 173 is movably installed between the two sliding grooves 172. The top left and right sides of the movable plate 173 are... Each side is fixedly installed with a limiting block 174, one end of which extends into the interior of the rectangular groove 7 and is respectively attached to the bottom of the two traction blocks 9. The bottom left and right sides of the rectangular block 6 are provided with mounting holes that are adapted to the limiting block 174. The top of the left limiting block 174 is attached to the bottom left side of the left traction block 9, and the top of the right limiting block 174 is attached to the bottom right side of the right traction block 9. Two limiting springs 175 are fixedly installed between the moving plate 173 and the rectangular block 6, located on opposite sides of the two limiting blocks 174 and symmetrically distributed. An arc-shaped pull rod 176 is fixedly installed at the bottom of the moving plate 173 between the two mounting plates 171.

[0025] In use, the tops of the two support rods 2 can be fixedly connected to the top of the building wall to erect the mounting bracket. When it is necessary to install the ladder-type aluminum alloy cable tray body 3, first insert the two connecting blocks 5 at the bottom of the ladder-type aluminum alloy cable tray body 3 into the two connecting slots 4 respectively until the ladder-type aluminum alloy cable tray body 3 is in contact with the top of the support plate 1. Then, turn the handwheel 154 to drive the mounting shaft 151 and the drive bevel gear 152 to rotate, which in turn drives the threaded rod 8 to rotate through the driven bevel gear 153. During the rotation of the threaded rod 8, the two traction blocks 9 will move in opposite directions, which will in turn drive the two moving blocks 11 and the two positioning blocks 13 to move in opposite directions, so that the two positioning blocks 13 move into the two positioning slots 14 respectively, thereby fixing the two connecting blocks 5. When the two limiting slots 16 move to the top of the two limiting blocks 174 respectively, the two limiting springs Under the elastic force of the spring 175, the moving plate 173 and the two limiting blocks 174 will move upward, so that the two limiting blocks 174 will move into the two limiting grooves 16 respectively, thereby limiting and fixing the two traction blocks 9 and the two positioning blocks 13, thus completing the installation of the ladder aluminum alloy cable tray body 3. Conversely, when it is necessary to disassemble the ladder aluminum alloy cable tray body 3, the two limiting blocks 174 can be moved out of the two limiting grooves 16 by pulling down the arc-shaped pull rod 176. Then, the handwheel 154 can be turned in the opposite direction to drive the two traction blocks 9 and the two positioning blocks 13 to move relative to each other, so that the two positioning blocks 13 can be moved out of the two positioning grooves 14 respectively, thereby releasing the fixation of the two connecting blocks 5. At this time, the ladder aluminum alloy cable tray body 3 can be disassembled by pulling it upward, which facilitates the inspection, maintenance or replacement of the ladder aluminum alloy cable tray body 3.

[0026] In summary, this easy-to-install ladder-type aluminum alloy cable tray is installed by inserting two connecting blocks 5 at the bottom of the ladder-type aluminum alloy cable tray body 3 into the two connecting slots 4 until the ladder-type aluminum alloy cable tray body 3 is in contact with the top of the support plate 1. Then, the handwheel 154 is turned to drive the mounting shaft 151 and the drive bevel gear 152 to rotate, which in turn drives the threaded rod 8 to rotate through the driven bevel gear 153. During the rotation of the threaded rod 8, the two traction blocks 9 move in opposite directions, which in turn drives the two moving blocks 11 and the two positioning blocks 13 to move in opposite directions, so that the two positioning blocks 13 move into the two positioning slots 14 respectively, thereby fixing the two connecting blocks 5. When the two limiting slots 16 move into the two limiting blocks 14 respectively, the two positioning blocks 151 and the two positioning slots 152 move into the two positioning slots 154. When the cable tray is directly above the 74, the elastic force of the two limiting springs 175 will drive the moving plate 173 and the two limiting blocks 174 to move upward, so that the two limiting blocks 174 move into the two limiting grooves 16 respectively, thereby limiting and fixing the two traction blocks 9 and the two positioning blocks 13. At this time, the installation of the ladder-type aluminum alloy cable tray body 3 is completed. There is no need to use external tools to install bolts, which simplifies the installation process and makes it more convenient for users. This solves the problem that in the actual installation process of existing ladder-type aluminum alloy cable trays, such as when the cable tray is erected on the bracket, bolts are often used to fix the cable tray and the bracket, which makes the installation process more complicated and not conducive to use.
