[0024] 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.

[0025] Please see Figure 1-6 An adjustable low-voltage cable tray includes: a low-voltage cable tray 1, a fixing block 2 connected to one side of the low-voltage cable tray 1, a fixing bracket 3 movably connected to the middle position of the fixing block 2, a positioning hole 4 opened on the front of the fixing bracket 3, a positioning pin 5 movably connected to the inner wall of the positioning hole 4, a connecting block 6 connected to one end of the positioning pin 5, and a pull rod 7 connected to one side of the connecting block 6.

[0026] The inner bottom wall of the low-voltage cable tray 1 is connected to a partition 8. One side of the partition 8 is connected to a slide rail 9. One side of the slide rail 9 is movably connected to an adjusting plate 12. The top of the adjusting plate 12 is movably connected to a movable plate 16. This allows the low-voltage cable tray to be more conveniently adjusted in height by the staff, and the internal space can also be effectively divided according to the actual types of cables installed, making it more convenient and efficient for the staff to use, further meeting people's needs and bringing convenience to their work.

[0027] The fixed block 2 has a movable groove in the middle position. The fixed block 2 is movably connected to the fixed bracket 3 through the movable groove. The movable groove design makes it easier for the fixed bracket 3 to move and makes it more stable to adjust.

[0028] There are four fixing blocks 2, and each pair of fixing blocks 2 forms a group. The two groups of fixing blocks 2 are symmetrically arranged with the vertical line of the low-voltage cable tray 1 as the axis of symmetry. By setting four fixing blocks 2, the low-voltage cable tray 1 can be made more stable during use.

[0029] The inner top wall of the slide 9 is connected to a clamping spring 10, and the bottom end of the clamping spring 10 is connected to a clamping block 11. Through the design of the clamping spring 10 and the clamping block 11, the adjustment plate 12 can be adjusted more conveniently, and the internal space can be divided more easily.

[0030] The surface of the clamping block 11 abuts against the outer wall of the adjusting plate 12, and the surface of the clamping block 11 is arc-shaped. Through the design of mutual abutment, the adjusting plate 12 can play a certain role in fixing and limiting it, so that it will not slide.

[0031] The top of the adjusting plate 12 is connected to a fixing rod 13, the top of the fixing rod 13 is connected to a fixing plate 14, the bottom of the fixing plate 14 is connected to a connecting spring 15, the bottom of the connecting spring 15 is connected to the top of the movable plate 16, and the bottom of the movable plate 16 is connected to a clamping plate 17. Through the design of the connecting spring 15, the movable plate 16 and the clamping plate 17 can effectively adapt to cables of different sizes.

[0032] The top of the movable plate 16 has a fixing hole, and the shape and size of the fixing hole match the shape and size of the fixing rod 13. The fixing hole can better facilitate the adjustment of the fixing rod 13.

[0033] Among them, the clamping plate 17 is an arc-shaped clamping plate, and there are multiple clamping plates 17. By setting multiple clamping plates 17, the needs of multiple cable quantities can be met.

[0034] Working principle: When the height of the low-voltage cable tray 1 needs to be adjusted, the pull rod 7 is pulled, which in turn causes the connecting block 6 and the positioning pin 5 to be pulled out from one side of the fixed block 2. The height of the low-voltage cable tray 1 is then slowly raised or lowered. The fixed block 2 is then aligned with the new positioning hole 4. After the position is adjusted, the positioning pin 5 is inserted to complete the adjustment. At the same time, when the interior of the low-voltage cable tray 1 needs to be divided, the adjusting plate 12 is inserted between the appropriate clamping blocks 11. The clamping blocks 11 then clamp and fix the adjusting plate 12 under the force of the clamping spring 10, thus completing the work.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
