[0020] 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.

[0021] Please see Figures 1 to 6 This utility model provides an adjustable internal space power distribution box, including a box body 1 and two doors 2 rotatably connected to the front end of the box body 1. The two doors 2 are axially connected to the box body 1. When the doors 2 are opened, they can be fitted against the side of the box body 1, leaving the front of the box body 1 unobstructed and facilitating operation. The end of the positioning post 7 is made of magnetic material. When the doors 2 are fitted against the side of the box body 1, the resulting attraction improves the stability of the doors 2, effectively preventing them from swinging back and forth due to collisions or wind. Multiple guide rails 5 are connected to both sides inside the box body 1, with equal spacing between adjacent guide rails 5. The guide rails 5 are movably connected to support plates 3. The support plate 3 is connected to a positioning mechanism for positioning the support plate 3. The positioning mechanism includes a handle 4, two positioning pins 7, two springs 14, two connecting plates 11, and a rotating disk 12. The handle 4 is used to drive the rotating disk 12 to rotate, and the springs 14 are used to drive the positioning pins 7 to move closer to the corresponding guide rails 5. The two ends of the connecting plates 11 are connected to the positioning pins 7 and the rotating disk 12.

[0022] The positions of multiple support plates 3 are adjusted according to the height and size of the electrical components to improve the utilization of the internal space of the housing 1. After the support plate 3 is inserted into the corresponding guide rail 5, the handle 4 is released, and the stretched spring 14 drives the guide block 10, positioning post 7, and spring block 9 to move forward synchronously. The rotating disk 12 rotates at a certain angle, and the positioning post 7 connects with the positioning hole 13 of the guide rail 5, realizing the quick positioning and installation of the support plate 3 and improving the stability of the connection between the support plate 3 and the housing 1.

[0023] The guide rail 5 has a U-shaped cross-section. The support plate 3 is slidably connected to the guide rail 5. The guide rail 5 provides support for the support plate 3 and also improves the stability of the movement of the support plate 3. When the support plate 3 needs to be disassembled, it can be separated from the guide rail 5 by pulling the support plate 3.

[0024] The positioning mechanism also includes two spring blocks 9, two guide blocks 10, and a rotating shaft 6. A groove 8 is provided inside the support plate 3, and the spring blocks 9 and guide blocks 10 are slidably connected to the groove 8. Both ends of the rotating shaft 6 are connected to the rotating disk 12 and the handle 4. The spring blocks 9 and guide blocks 10 provide good guidance for the positioning pins 7, improving the stability of their movement. When the support plate 3 needs to be disassembled, rotating the handle 4 drives the rotating shaft 6 to rotate, which in turn drives the rotating disk 12 to rotate. The rotating disk 12 simultaneously applies tension to the two connecting plates 11, causing the two guide blocks 10 to move closer together, i.e., the two positioning pins 7 to move closer together. The positioning pins 7 separate from the positioning holes 13, thus loosening the support plate 3 and facilitating its removal. The operation is simple and convenient.

[0025] Spring block 9 and guide block 10 are fixedly connected to positioning post 7, and spring block 9 is located on one side of guide block 10.

[0026] Spring 14 is fitted onto positioning post 7, and both ends of spring 14 are connected to spring block 9 and support plate 3.

[0027] The two ends of the connecting plate 11 are connected to the guide block 10 and the rotating disk 12 via shafts.

[0028] The guide rail 5 is provided with positioning holes 13 that match the positioning posts 7. When installing the support plate 3, the inner side of the support plate 3 abuts against the inner side of the housing 1, and the inner side of the housing 1 is... Figure 2 At point c, the support plate 3 stops moving forward, and the positioning post 7 is precisely aligned with the positioning hole 13, facilitating subsequent docking.

[0029] Working Principle: The positions of multiple support plates 3 are adjusted according to the height and size of electrical components to accommodate the installation of components of corresponding sizes, thus improving the space utilization within the housing 1. The support plate 3 is aligned with the guide rail 5 and pushed into the housing 1. Then, the handle 4 is released, causing the stretched spring 14 to drive the spring block 9, guide block 10, and positioning post 7 to move forward synchronously. The rotating disk 12 rotates at a certain angle, connecting the positioning post 7 with the positioning hole 13 of the guide rail 5, achieving rapid positioning and installation of the support plate 3 and improving the stability of the connection between the support plate 3 and the housing 1. When disassembling and rearranging the support plate 3, rotating the handle 4 drives the rotating shaft 6 and rotating disk 12 to rotate. The rotating disk 12 applies a synchronous pulling force to the two connecting plates 11, causing the two guide blocks 10 to move closer together, i.e., the two positioning posts 7 to move closer together. This separates the positioning post 7 from the positioning hole 13 of the guide rail 5, loosening the support plate 3 for easy rearrangement.

[0030] 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.
