Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6, a small-scale electric energy meter box based on indoor use, includes a box body 1, and one side of the inner wall of the box body 1 is hinged with multiple placement plates 2, which can classify and place multiple electrical components. The top of the placement plate 2 is fixedly connected with a magnet 16 that is attracted to the inner wall of the box body 1, and the number of magnets 16 on the placement plate 2 is two, and they are symmetrically arranged on the top of the placement plate 2. When people rotate the placement plate 2 to make it fit with the inner wall of the box body 1, the magnets 16 will be attracted to the inner wall of the box body 1, thereby playing a good fixing effect on the placement plate 2, thereby making it more convenient for staff to repair the inside of the box body 1. A groove 17 is opened on one side of the placement plate 2, and the corners at the opening of the groove 17 are all rounded. However, when people need to rotate the placement plate 2 to make it horizontal, they can insert their hands into the groove 17 on the placement plate 2, and then they can more easily pull the placement plate 2 to make it horizontal. A plurality of through holes 19 are opened on the placement plate 2. After the staff installs the electrical components on the placement plate 2, they pass the lines through the wire holes at the bottom of the box body 1, and then through After passing through the through hole 19, it is connected with the electrical component, and the small-scale electric energy meter box can be used normally. One side of the inner wall of the box body 1 is located at the bottom of the placement plate 2 and is rotatably connected with a symmetrical support plate 3, which can play a good supporting role for the placement plate 2, so that the electrical component is placed on the placement plate 2. Stability is higher, and a sliding cavity 4 is opened at one end of the support plate 3, and the extension plate 5 is slidably connected inside the sliding cavity 4. A symmetrical second spring 13 is fixedly connected to the side of the inner wall of the sliding cavity 4 away from the extension plate 5, and the other end of the second spring 13 is fixedly connected to the extension plate 5. Pull blocks 18 are fixedly connected to both sides of the extension plate 5, and the corners of the pull blocks 18 are all rounded. Symmetrical fixing blocks 6 are fixedly connected to the bottom of the placement plate 2, and a slot 7 matching the extension plate 5 is opened on one side of the fixing block 6. Limiting components are set at one end of the extension plate 5 away from the support plate 3 on both sides. Pull the extension plate 5 to insert it into the slot 7, and the extension plate 5 can be limited and fixed by the limiting component. The small-scale electric energy meter box can be used normally and has high stability.

When the extension plate 5 completely enters the slot 7, the wedge block 9 will pop out under the action of the first spring 10 and engage with the through groove 11, which can play a good limiting role for the extension plate 5. Then the electrical components can be installed on the top of the placement plate 2, and the circuits are passed through the wire holes at the bottom of the box body 1, and then through After passing through the through hole 19 and connecting with the electrical components, the small electric energy meter box can be used normally. When people need to inspect the interior of the box body 1, after removing the electrical components on the placement plate 2, pressing the pressing blocks 12 on both sides of the fixing block 6 at the same time can push the wedge block 9 to slide into the slide groove 8. When the wedge block 9 is completely out of the through groove 11, the extension plate 5 can be slid away from the fixing block 6, and then the placement plate 2 can be rotated to make it fit with the interior of the box body 1. At the same time, the magnet 16 on the placement plate 2 will be attracted to the inner wall of the box body 1, thereby better fixing the placement plate 2, thereby making it more convenient for the staff to repair the interior of the box body 1.
