[0038] like Figure 2 , Figure 3 and Figure 4 As shown, the first moving mechanism 2 is arranged in the housing 1, and the first moving mechanism 2 is connected to the first moving plate 12 by transmission. The first moving mechanism 2 is used to drive the first moving plate 12 to move along the first direction, so that the position of the first moving plate 12 along the first direction can be adjusted. The second moving mechanism 3 is connected to the first moving plate 12, and the movement of the first moving plate 12 along the first direction drives the second moving mechanism 3, and the second moving mechanism 3 is connected to the second moving plate 13 by transmission.

[0039] Optionally, the distribution box cabinet further includes a first driving mechanism 4, the first driving mechanism 4 includes a first connecting shaft 41, and the first moving mechanism 2 includes a first gear 21, a first transmission gear 22, a first screw 23 and a first nut 24. The two ends of the first connecting shaft 41 are rotatably connected to the two opposite side walls of the housing 1, the first gear 21 is sleeved on the outer periphery of the first connecting shaft 41, and the first connecting shaft 41 drives the first gear 21 to rotate. The first screw 23 is arranged on one side of the first connecting shaft 41, and the first screw 23 is arranged parallel to the first connecting shaft 41. The first nut 24 is screwed to the first screw 23, the first transmission gear 22 is sleeved on the first screw 23, and the first gear 21 is meshed with the first transmission gear 22, so that the rotation of the first connecting shaft 41 can drive the first screw 23 to rotate, thereby driving the first nut 24 to move linearly along the first direction through the rotation of the first screw 23, and the first moving plate 12 is connected to the first nut 24, thereby realizing the position adjustment of the first moving plate 12 in the first direction. The first driving mechanism 4 and the first moving mechanism 2 can realize accurate and stable positioning and adjustment of electronic components in the distribution cabinet, thereby improving the adaptability and reliability of the distribution cabinet in high-altitude areas.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, optionally, the first driving mechanism 4 includes a guide rod 47. The first nut 24 is connected to one end of the first movable plate 12, and the guide rod 47 is slidably connected to the other end of the first movable plate 12, and the guide rod 47 is parallel to the first lead screw 23. The setting of the guide rod 47 can make the first movable plate 12 more stable when moving linearly along the first direction, avoiding the deviation of the first nut 24 or the first movable plate 12 caused by the special environment of high altitude areas, thereby improving the accuracy and reliability of the internal structure adjustment of the entire distribution box cabinet. In addition, the setting of the guide rod 47 can prevent the first movable plate 12 and the first nut 24 from rotating around the first lead screw 23, so that the first lead screw 23 can drive the first nut 24 to achieve linear movement.

[0041] like Figure 2 , Figure 3 and Figure 4As shown, optionally, the first driving mechanism 4 includes a first bevel gear 42, a second bevel gear 43, a transmission shaft 44 and a connecting plate 45. The connecting plate 45 is connected to the housing 1, and the transmission shaft 44 is rotatably connected to the connecting plate 45 through a bearing. The second bevel gear 43 is sleeved on the outer periphery of the transmission shaft 44, and the first bevel gear 42 is sleeved on the outer periphery of the first connecting shaft 41. The second bevel gear 43 is meshed with the first bevel gear 42, so that the rotation of the transmission shaft 44 drives the first connecting shaft 41 to rotate. The rotation of the transmission shaft 44 can be transmitted to the first connecting shaft 41 through the meshing of the first bevel gear 42 and the second bevel gear 43, and then the first lead screw 23 is driven to rotate, so that the first movable plate 12 moves along the first direction, and the threaded connection can improve the stability and reliability of the movement. The axis of the transmission shaft 44 is perpendicular to the first connecting shaft 41, and the axis of the transmission shaft 44 is perpendicular to the mounting plate 11, so that the end of the transmission shaft 44 can be convenient for hand-held rotation, reducing the difficulty of operation.

[0042] Optionally, the first driving mechanism 4 includes a handle 46, and the handle 46 is connected to the end of the transmission shaft 44 away from the first connecting shaft 41.

It is understandable that the transmission shaft 44 can also be connected to a motor to realize drive rotation and improve convenience.

The plurality of first movable plates 12 cooperate with the corresponding plurality of first movable mechanisms 2, so that the plurality of first movable plates 12 can be adjusted simultaneously by the first driving mechanism 4, thereby increasing or decreasing the spacing between the electronic components by moving the electronic components at different positions, achieving accurate space utilization and layout optimization, and improving the flexibility and adaptability of the arrangement of components inside the distribution cabinet in high altitude areas.

[0044] like Figure 2 , Figure 4 and Figure 5As shown, optionally, along the first direction, the pitch of the first lead screw 23 at the rear end is smaller than the pitch of the first lead screw 23 at the front end, that is, the pitch of the first lead screw 23 close to the handle 46 is smaller than the pitch of the first lead screw 23 away from the handle 46. Among the multiple first lead screws 23 arranged along the first direction, the first lead screw 23 at the rear end has a smaller pitch, and the first lead screw 23 at the front end has a larger pitch, so that the first driving mechanism 4 can drive different first moving mechanisms 2 at the same time; and through the same first driving mechanism 4, the moving distances of the first nuts 24 of different first moving mechanisms 2 are different, so as to achieve the adjustment effect of synchronously increasing or decreasing the distance between different first moving plates 12, and improve the convenience of operation.

[0045] like Figure 2 and Figure 4 As shown, in this embodiment, the first direction is the vertical direction from bottom to top, the second direction is the horizontal direction from right to left, and three first lead screws 23 are provided, and the pitches of the three first lead screws 23 increase in sequence from bottom to top, so that the vertical distances between the corresponding three first movable plates 12 are increased or decreased when driven simultaneously. Specifically, the sum of the pitches of the first lead screw 23 at the bottom and the first lead screw 23 at the top can be made twice the pitch of the first lead screw 23 in the middle, so that the vertical distances between the three first movable plates 12 are basically the same, and can achieve basically synchronous increase or decrease; it can be understood that the relationship between the pitches of different first lead screws 23 includes but is not limited to the above forms, which can be set as needed.

[0046] like Figure 2 , Figure 4 and Figure 5As shown, optionally, the distribution box cabinet also includes a second driving mechanism 5, the second driving mechanism 5 includes a rack 51, a linkage gear 52 and a second connecting shaft 53, and the second moving mechanism 3 includes a second gear 31, a second transmission gear 32, a second lead screw 33 and a second nut 34. The rack 51 is arranged on the mounting plate 11, and the length of the rack 51 extends along the first direction. The second connecting shaft 53 is arranged on a side of the first moving plate 12 close to the rack 51, and the two ends of the second connecting shaft 53 are rotatably connected to the second moving plate 13. The linkage gear 52 and the second gear 31 are both sleeved on the outer periphery of the second connecting shaft 53, and the linkage gear 52 is meshed with the rack 51. The second lead screw 33 is rotatably connected to the first movable plate 12. The second lead screw 33 and the second connecting shaft 53 are arranged on the same side of the first movable plate 12. The axis of the second lead screw 33 is parallel to the axis arranged on the second connecting shaft 53. The second transmission gear 32 is sleeved on the outer periphery of the second lead screw 33. The second transmission gear 32 is arranged at a position where the second lead screw 33 is not provided with threads. The second transmission gear 32 is fixedly connected to the second lead screw 33. The second transmission gear 32 is meshed with the second gear 31, so that the rotation of the second connecting shaft 53 can drive the second lead screw 33 to rotate. The second nut 34 is slidably matched with the first movable plate 12 to limit the rotation of the second nut 34, so that the second lead screw 33 drives the second nut 34 to move linearly along the second direction, and the second movable plate 13 is connected to the second nut 34. The coordination between the rack 51 and the linkage gear 52 and the transmission between the second lead screw 33 and the second nut 34 ensure the stable movement of the second movable plate 13 in the second direction, improve the positioning accuracy and reliability of the internal components of the distribution cabinet, facilitate stable operation in high-altitude environments, and enhance the adaptability of the overall structure.

[0047] like Figure 2 , Figure 4 and Figure 5 As shown, optionally, the second movable plate 13 and the second movable mechanism 3 on the same first movable plate 12 are both provided with a plurality of them and are distributed along the second direction, and the second movable plate 13 and the second movable mechanism 3 are correspondingly arranged. The second movable plate 13 and the second movable mechanism 3 on the same first movable plate 12 are both provided with a plurality of them, so that each second movable plate 13 can be adjusted independently, further enhancing the flexibility and adjustment accuracy of the components inside the distribution box cabinet. The corresponding arrangement of the second movable plate 13 and the second movable mechanism 3 ensures that each second movable plate 13 can accurately move along the second direction, improving the utilization efficiency of the internal space of the distribution box cabinet and the installation accuracy of the components. The second drive mechanism 5 can be provided with a plurality of them, and the second drive mechanism 5 is arranged corresponding to the first movable plate 12, so as to be able to adjust the positions of the plurality of second movable plates 13 on each first movable plate 12 respectively. The diameter of the linkage gear 52 of each second drive mechanism 5 can be set as needed, so that the distance between the plurality of second movable plates 13 on different first movable plates 12 meets the needs.

[0048] like Figure 2 , Figure 4 and Figure 5 As shown, optionally, along the second direction, the pitch of the second lead screw 33 at the rear end on the same first movable plate 12 is smaller than the pitch of the second lead screw 33 at the front end, that is, the pitch of the second lead screw 33 away from the guide rod 47 is smaller than the pitch of the second lead screw 33 close to the guide rod 47. The multiple second lead screws 33 arranged along the second direction have different pitches, and the pitch of the second lead screw 33 at the rear end is smaller than the pitch of the second lead screw 33 at the front end, thereby realizing nonlinear displacement adjustment in the second direction, and the same second driving mechanism 5 can drive different second screw nuts 34 to realize different displacements, so that the distances between the multiple second movable plates 13 on the same first movable plate 12 are all adjusted, thereby improving the flexibility and accuracy of adjusting the internal components of the distribution cabinet in high-altitude areas.

[0049] In this embodiment, the second drive mechanism 5 corresponds to the first lead screw 23, and three second drive mechanisms 5 are provided. From bottom to top, the diameter of the linkage gear 52 gradually increases (not shown in the figure); specifically, the sum of the diameters of the linkage gear 52 located at the bottom and the linkage gear 52 located at the top is twice that of the linkage gear 52 located in the middle, so that the speed difference obtained by each second connecting shaft 53 is reduced. Correspondingly, the three racks 51 corresponding to the three linkage gears 52 can cooperate with the linkage gear 52. Similarly, three second lead screws 33 can be provided on each first moving plate 12, and the arrangement of the three second lead screws 33 is similar to the arrangement of the three first lead screws 23. It can be understood that the pitch relationship of different first lead screws 23, the pitch relationship of different second lead screws 33, the diameter relationship of different linkage gears 52, and the size relationship between other structures can be set according to actual needs, and can meet the use needs. It can be understood that the distribution box cabinet also includes necessary structures for connection, support, driving, positioning, limiting, sealing and control functions so that the distribution box cabinet can operate normally; the shape, size, material, setting quantity and other parameters of each part of the distribution box cabinet can be determined according to needs as long as the corresponding functions can be realized.
