[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an adjustable mounting rail assembly for a power distribution cabinet according to this utility model includes a rail 1 and multiple fixing plates 12. The fixing plates 12 are all arranged parallel to each other on the back of the rail 1. An adjustment groove is provided on the side of the fixing plate 12 facing the rail 1. An adjustment block 15 is slidably installed in the adjustment groove. The rail 1 is provided with mounting holes opposite to the adjustment block 15. A sealed bearing 2 is installed in each mounting hole. A shaft 3 is installed in the inner ring of each sealed bearing 2. The other end of the shaft 3 is installed on the adjustment block 15. A lead screw 9 is provided inside the adjustment groove to drive the adjustment block 15 to move. One end of the lead screw 9 extends to the outside and is equipped with a rotating mechanism. A magnetic suction assembly is installed on the back of the rail 1 between the fixing plates 12. The adjustment block is provided with a lead screw hole, and the lead screw is threaded into the lead screw hole so that the rotation of the lead screw can smoothly drive the movement of the adjustment block.
[0024] In this embodiment, the rotating mechanism includes a small gear 4, a large gear 5, a handwheel 7, a rotating rod 6, and a fixed frame 8. The small gear 4 is installed on the exposed end of the lead screw 9. One end of the fixed frame 8 is installed on the fixed plate 12, and the other end is bent and extended to the outside of the small gear 4. A first ball bearing is embedded in the inner side of the fixed frame 8. The rotating rod 6 is installed in the inner ring of the first ball bearing. The large gear 5 and the handwheel 7 are installed on the rotating rod 6. The large gear 5 is meshed with the small gear 4.
[0025] In this embodiment, the magnetic suction assembly includes a magnet 10, which is mounted on the track 1. Positioning grooves 13 are provided on both sides of the magnet 10. One end of the fixing plate 12 is attached to the magnet 10, and one end of the fixing plate 12 protrudes to form a positioning part 14, which is inserted into the positioning groove 13.
[0026] In this embodiment, the end of the adjusting groove away from the rotating mechanism is embedded with a second ball bearing, and the other end of the lead screw 9 is installed in the second ball bearing.
[0027] In this embodiment, both the adjusting block 15 and the adjusting groove have trapezoidal cross-sections, which allows the adjusting block to move back and forth along the adjusting groove, thus avoiding direct detachment.
[0028] In this embodiment, the diameter of the handwheel 7 is larger than the diameter of the large gear 5. The larger handwheel facilitates the rotation of the large gear and the small gear, while the large gear drives the small gear to rotate the lead screw more quickly.
[0029] In this embodiment, the fixing plates 12 are all made of metal material, so that they can be attracted and fixed by magnets.
[0030] In this embodiment, the inner wall of the adjustment groove is provided with multiple countersunk holes 11 that penetrate the track 1. Bolts can pass through the countersunk holes and be fixed in the distribution cabinet. The head of the bolt is hidden inside the countersunk hole, thus avoiding protrusion from the inner wall of the adjustment groove.
[0031] When not in use, the fixed plate is rotated around the shaft to the back of the track and parallel to it. Once parallel, the fixed plate can be attracted and fixed by the magnet, and the positioning part on the fixed plate can be inserted into the positioning groove, which increases the stability after parallelism, improves positioning, reduces volume, and makes it easy to carry. The two corners of the fixed plate facing the magnet and the two ends of the positioning part are provided with arc-shaped chamfers 16. The chamfers 16 allow the fixed plate to rotate smoothly off the magnet, and the positioning part can be pushed out of the positioning groove after being pushed by the outside, avoiding jamming.
[0032] In use, rotating the fixing plate around the shaft detaches it from the magnet, allowing the positioning part to move out of the positioning slot. The fixing plate can then rotate around the shaft until it is vertically positioned. Screws pass through the countersunk holes to secure the fixing plate in the distribution cabinet. After fixing, a handwheel drives the rotating rod, which in turn drives the large gear. The large gear synchronously drives the small gear and the lead screw. The rotation of the lead screw drives the adjusting block and the track, allowing the track to move stably up and down, increasing adaptability. The larger handwheel facilitates rotation operation, enhancing convenience.
[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
