[0012] 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.

[0013] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, an expandable structure of the modular energy metering box proposed in one embodiment of this utility model includes two boxes 1, each with a door 3 hinged to it. A connecting component 4 is provided on each door 3. A heat dissipation hole 9 is provided on one side of each box 1, and a surrounding plate 5 is fixedly installed on one side of each box 1. Sliding grooves are provided on both sides of the inner cavity of the surrounding plate 5, and sliders 6 are slidably connected inside each of the two sliding grooves. A sealing plate 7 is installed between the two sliders 6, and a positioning hole is provided on one side of the sealing plate 7. A fixing component 8 is provided on the surrounding plate 5, and bolts 2 connect the two boxes 1 together. The assembly of the two boxes 1 expands the internal space of the modular energy metering box. The fixing component 8 allows the box 1 to be sealed when not in use, preventing dust and impurities from entering and improving internal protection. The connecting component 4 connects and fixes the two doors 3, facilitating subsequent maintenance of the modular energy metering box. The fixing component 8 includes a side plate 81 fixedly installed on one side of the enclosure 5. Two limiting rods 82 are fixedly installed inside the side plate 81. A slide plate 83 is slidably connected between the two limiting rods 82. An extension plate 84 is fixedly installed on one side of the slide plate 83. The extension plate 84 is slidably connected to the side plate 81. A locking plate 85 is fixedly installed on one side of the extension plate 84. Two compression springs 87 are fixedly connected to one side of the slide plate 83. The compression springs 87 are fixedly connected to the side plate 81. A hand ring 86 is fixedly installed on one side of the locking plate 85. Pulling the hand ring 86 causes the locking plate 85 to slide along the extension plate 84 and the slide plate 83 on the limiting rods 82 for guidance, compressing the compression springs 87. Then, the sealing plate 7 slides into the groove along with the slider 6. As the compression spring 87 returns to its original position, the locking plate 85 is engaged in the positioning hole, completing the limiting of the sealing plate 7. The sealing plate 7 can be disassembled during use and heat dissipation is achieved through the heat dissipation holes 9.

[0014] like Figure 4 As shown, in some embodiments, the card plate 85 slides within the positioning hole; this facilitates positioning.

[0015] like Figure 3As shown, in some embodiments, the connecting assembly 4 includes a connecting plate 41 fixedly installed on one of the cabinet doors 3, and two fixing blocks 47 fixedly installed on the other cabinet door 3. The two fixing blocks 47 have grooves 48 at their close ends. Four sliding rods 42 are fixedly installed inside the connecting plate 41. A sliding seat 43 is slidably connected between two sliding rods 42 on the same side. A positioning plate 44 is fixedly installed on one side of each of the two sliding seats 43, and a handle 45 is fixedly installed on the other side of each of the two sliding seats 43. A return spring 46 is fixedly connected to the opposite side of each of the two sliding seats 43. The return spring 46 is fixedly connected to the connecting plate 41. By rotating the two cabinet doors 3, the two handles 45 are squeezed, causing the sliding seats 43 to slide on the sliding rods 42, which squeezes the return spring 46. After the two cabinet doors 3 are in contact, the return spring 46 resets, causing the positioning plate 44 to be inserted into the groove 48, thus completing the limiting work of the two cabinet doors 3.

[0016] like Figure 3 As shown, in some embodiments, the positioning plate 44 slides within the groove 48; this facilitates connection and limiting, ensuring the stability of the door 3.

[0017] The wiring diagrams of the electrical components in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use, so the control method and wiring layout will not be explained in detail.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
