[0038] refer to Figure 4-Figure 5 There are multiple mounting seats 20, all of which are arranged in the empty slot 12 and are located on one side of the placement slot 11. A through slot 21 is opened in the middle of each mounting seat 20, and an elastic member 22 is arranged between two adjacent mounting seats 20 for elastically supporting the adjacent mounting seats 20. In this solution, the elastic member 22 is specifically a spring. A limiting slot 23 is opened inside the mounting seat 20 along its height direction to facilitate the installation of the adjustment member 40. A slide seat 24 is fixedly installed on the top of the mounting seat 20, and the slide seat 24 is slidably assembled inside the top slot 13 to facilitate the movement of the mounting seat 20 in the empty slot 12.
[0039] refer to Figure 5 , Figure 7 , Figure 8 as well as Fig. 9 The partition assembly 30 includes a hanger plate 31 and a partition plate 32. The hanger plate 31 is fixedly installed at the bottom of the mounting base 20 and extends to the inside of the placement groove 11. The partition plate 32 is tilted and rotatably assembled at the bottom of the hanger plate 31. The adjacent busbars can be supported and separated by the two ends of the partition plate 32. By rotating the partition plate 32 on the hanger plate 31 and adjusting the inclination angle of the partition plate 32, the horizontal distance between the upper and lower ends of the partition plate 32 can be changed, and the separation distance between two adjacent busbars can be adjusted, thereby adapting to the support of busbars of different thicknesses. A slide groove 321 is opened inside the partition plate 32, and a side groove 322 is opened on the side wall of the slide groove 321.

The push plate 51 has two symmetrically distributed at the two ends of the placement groove 11, and the two push plates 51 are respectively close to the mounting seats 20 at the two ends of the placement groove 11. The limit block 52 is fixedly installed on the top of the push plate 51, and the top of the limit block 52 is slidably assembled inside the top groove 13. The limit block 52 slides along the top groove 13 to make the push plate 51 move in the empty groove 12, so that the two push plates 51 are close to each other and then push the two mounting seats 20 at the ends, so that the mounting seats 20 at the two ends of the placement groove 11 are close to the middle, so that the several mounting seats 20 located in the middle and the elastic member 22 push each other and move, so that the multiple partitions 32 push the busbar to the middle. To complete the clamping and positioning of the busbar, a first lead screw 53 rotatably assembled on the cross plate 10 is arranged in the empty slot 12, and two sets of threads with opposite rotation directions are arranged on the first lead screw 53, and two push plates 51 are respectively threadedly connected to the outside of the two sets of threads of the first lead screw 53, and a knob is arranged on the end of the first lead screw 53, and the first lead screw 53 passes through the through slot 21 on the mounting seat 20, and the diameter of the through slot 21 is larger than the diameter of the first lead screw 53, so that the first lead screw 53 and the mounting seat 20 do not contact each other, and when the first lead screw 53 is rotated, the two push plates 51 can be pushed to move in opposite directions synchronously, approach each other or move away from each other, and then the distance between adjacent mounting seats 20 is adjusted to increase or decrease synchronously.
[0043] refer to Figure 6 The lifting assembly 60 includes a rotating seat 61, a second lead screw 62 and a threaded barrel 63. The rotating seat 61 is rotatably assembled on one of the horizontal plates 10, the second lead screw 62 is fixedly mounted on the rotating seat 61, and the threaded barrel 63 is fixedly mounted on the other horizontal plate 10 and is threadedly connected to the outside of the second lead screw 62. The second lead screw 62 is driven to rotate by the rotating seat 61, so that the second lead screw 62 pushes the threaded barrel 63 to move, and the spacing between the two horizontal plates 10 can be adjusted to adapt to busbars of different widths.
[0044] refer to Figure 1-Figure 3 The power distribution cabinet of the present invention includes a cabinet body 2 and a mounting frame 70. The mounting frame 70 is fixedly installed inside the cabinet body 2. A slide 71 is slidably mounted inside the mounting frame 70, and a cross plate 10 is fixedly installed on the slide 71. The cross plate 10 can be supported by the slide 71, and the height of the cross plate 10 can be adjusted as the slide 71 slides. A vertical groove 72 is opened in the side wall of the mounting frame 70, and a screw rod 73 is fixedly installed on the side wall of the slide 71, and the screw rod 73 passes through the vertical groove 72. The external thread of the screw rod 73 is connected with a locking nut 74, and the locking nut 74 is tightly pressed against the side wall of the mounting frame 70, thereby locking the position of the slide 71 to keep the bracket 1 at a fixed height.
[0045] Working principle: The slide 71 slides in the mounting frame 70 to adjust the bracket 1 to a suitable height, and then the screw 73 cooperates with the locking nut 74 to fix and lock the position of the bracket 1, and the end of the busbar is placed between two adjacent partitions 32. The second screw 62 is driven to rotate by the rotating seat 61, so that the second screw 62 pushes the threaded tube 63 to move, so that the two cross plates 10 are close to the upper and lower sides of the busbar, and the adjusting bolt 413 is turned to push the base 412 down, so that the cross bar 41 drops in the empty slot 12, and the push rod 42 pushes the partition 32 to rotate on the hanging plate 31 to adjust the inclination of the partition 32. The bevel angle changes the horizontal distance between the upper and lower ends of the partition 32, and the separation distance between two adjacent busbars is adjusted to be consistent with the thickness of the busbar. Then the first screw 53 is rotated to push the two push plates 51 closer to each other through the two sets of reverse threads on its outside, so that the push plates 51 push the mounting seats 20 at both ends of the mounting groove 11 to move closer to the middle, so that the several mounting seats 20 and the elastic member 22 located in the middle push and move each other, so that multiple partitions 32 push the busbars to move closer to the middle to complete the clamping and fixing of the busbars, and bolts, anchor rods and other parts can be used to reinforce the multiple busbars.
[0046] In the present invention, adjacent busbars are separated by partitions 32. By adjusting the inclination angle of the partitions 32, the separation distance between adjacent busbars can be quickly adjusted, so that the bracket 1 can better adapt to the equidistant separation of busbars of different thicknesses, thereby enhancing the versatility of the equipment. The partitions 32 are driven to gather through the mounting seat 20, so that after the busbars are separated by the partitions 32, the busbars can be quickly clamped and positioned, thereby improving the convenience of fixing the busbars and further improving the installation efficiency of the busbars.
