[0003] The patent with publication number CN219717612U discloses a modular electric energy metering box, including an outer box body, two connecting columns are fixedly connected inside the outer box body, a plurality of inner boxes are arranged inside the outer box body, and a connecting mechanism is arranged on the plurality of inner boxes, and the connecting mechanism includes a connecting shaft, two bidirectional screws are fixedly connected to the connecting shaft, and each of the bidirectional screws is threadedly connected with a movable nut, a limiting rod is arranged on one side of the movable nut, a fixed shaft is fixedly connected to the inner box body, and two connecting clamps are rotatably connected to the fixed shaft, and a connecting rod is arranged between the two connecting clamps and the two movable nuts; the utility model sets a connecting mechanism and a connecting column, rotates the locking knob to drive the connecting rod to move, and the movement of the connecting rod drives the connecting clamp to rotate, so that the two connecting clamps clamp the connecting column, thereby facilitating the loading and unloading and maintenance of the modular inner box, and improving the convenience of use and maintenance.

[0004] In the specific use of the above-mentioned prior art, a connecting mechanism and a connecting column are set, and the locking knob is turned to drive the connecting rod to move, and the movement of the connecting rod drives the connecting clamp to rotate, so that the two connecting clamps clamp the connecting column, thereby facilitating the loading and unloading and maintenance of the modular inner box, and improving the convenience of use and maintenance. However, after the connecting mechanism is connected to the connecting column, it cannot support the inner box. Multiple inner boxes will be stacked together, affecting the heat dissipation effect of the inner box. In addition, the structure of the connecting mechanism is too complicated. The connecting mechanism is installed on the inner box and will be moved out with the inner box. When the inner box is repaired, the connecting mechanism is easily damaged. Therefore, the above-mentioned prior art is not convenient to use in actual application. In view of this, we propose a modular electricity metering box. Utility Model Content
