[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an electric energy metering box, including a box body 1 and a box door 2 rotatably installed on the front of the box body 1. Connecting frames 3 are slidably installed on the left and right sides of the box body 1. The connecting frames 3 can slide into the interior of the box body 1 or extend to the outside of the box body 1. Slots 6 are provided inside the connecting frames 3, and the slots 6 are provided on both sides. The side close to the box door 2 is a through groove, and the groove on the other side is not through. A side plate 4 is movably connected inside the slot 6. The side plate 4 can be inserted forward or backward. A connecting groove 10 is provided inside the connecting frame 3 and on one side of the slot 6. The connecting groove 10 is located in the middle of the connecting frame 3. A connecting plate 8 that can be inserted into the connecting groove 10 is installed on the inner side of the box body 1. The connecting plate 8 can be inserted into the connecting groove 10 by moving back and forth to fix the position of the connecting frame 3. When two box bodies 1 are connected, the connecting plate 8 can fix the connecting frame 3 inside the other box body 1.

[0019] Wherein, flap plates 5 are fixedly connected to the upper and lower ends of the connecting frame 3 and near the edges of the box body 1. A first spring 7 is installed between the flap plates 5 and the inner wall of the box body 1. The first spring 7 always pulls the flap plates 5 to move towards the outside of the box body 1.

[0020] Wherein, the connecting plate 8 has an L-shaped structure. The smooth surface of the connecting plate 8 is in sliding fit with the inner wall of the box body 1. Second springs 9 are fixedly connected between the upper and lower ends of the side of the connecting plate 8 close to the box body 1 and the inner wall of the box body 1. The second springs 9 always push the connecting plate 8 against the connecting frame 3.

[0021] Wherein, a filter screen 11 is provided inside the side plate 4. The filter screen 11 can filter dust from the outside and at the same time dissipate heat from the interior of the box body 1.

[0022] Specifically, when it is necessary to add a box body 1 to one side of the box body 1, the side plate 4 on the side of the originally installed box body 1 that needs to be added can be taken out. Then, press the connecting plate 8 to contract the second spring 9, so as to retract the connecting frame 3 into the interior of the box body 1. Then, insert the connecting frame 3 corresponding to the new box body 1 into the interior of this fixed box body 1. Then, release the connecting plate 8, so that the connecting plate 8 is inserted into the connecting groove 10 on the newly inserted connecting frame 3 under the elastic force of the second spring 9, thereby completing the fixation between the two box bodies 1. Then, place the removed side plate 4 at the bottom of the box body 1.
