Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1 - Figure 5 The electric energy meter box shown includes a box body 1, in which a horizontal plate 3 is fixedly installed, and a vertical plate 4 is fixedly connected to the top of the horizontal plate 3 at equal intervals. A limit plate 5 is fixedly installed on one side of the top of the vertical plate 4, and a front side of the horizontal plate 3 is provided with equidistant holes 301, and a guide column 6 is fixedly inserted in each of the jacks 301. The ends of multiple limit plates 5 are movably penetrated by a mounting plate 8, and a support plate 7 is inserted into the bottom end of the mounting plate 8. Slide grooves 701 slidably connected to the guide column 6 are symmetrically provided on both sides of the support plate 7. Terminals 702 for terminal wiring are equidistantly arranged on one side of the support plate 7. A voltmeter 9 is fixedly installed on one side of the front side of the mounting plate 8, and the terminal at the bottom of the voltmeter 9 is plugged into the terminal 702.

[0023] The box 1 provides a protective shell for the overall device, avoiding the influence of the external environment on the internal components.

At the same time, the voltmeter 9 is plugged into the wiring end 702, making the subsequent replacement and maintenance of the voltmeter more convenient, without the need to rearrange the circuit, achieving the effect of convenient operation.

[0024] The side of the supporting plate 7 close to the wiring end 702 is fixedly connected with a handle 703 for pulling the supporting plate 7, providing a force point for the staff to pull the supporting plate 7, making the pulling operation of the supporting plate 7 more convenient and labor-saving, improving the efficiency of wiring, maintenance and other work. The back of the mounting plate 8 is fixedly connected with a side plate 11 on both sides, and the side plate 11 and the mounting plate 8 form a cavity for storing cables. The front of the mounting plate 8 is fixedly installed with a circuit breaker 10 for controlling the on-off of the circuit of the voltmeter 9. The cavity formed by the side plate 11 and the mounting plate 8 can store excess cables, avoiding the messy storage of cables affecting the internal cleanliness and subsequent operation of the device, and reserving enough line length when the voltmeter 9 is pulled out. The circuit breaker 10 can control the on-off of the circuit where the voltmeter 9 is located. When the voltmeter 9 needs to be repaired or the circuit fails, the circuit can be cut off through the circuit breaker 10, ensuring the safety of the staff operation.

The door plates 2 can shield and protect the corresponding areas inside the box 1, and their width matches the width of the supporting plate 7, so that each supporting plate 7 corresponds to an independent door plate 2, facilitating the staff to open the corresponding door plate 2 to operate the components on the supporting plate 7, improving the accuracy and efficiency of maintenance and repair.

[0026] The front of the box 1 is hinged on the top side of the door plate 2, and the end of the mounting block 202 is fixedly connected with the air cylinder 203, and the telescopic end of the air cylinder 203 is fixedly connected with the connecting block fixedly connected with the front side of the door plate 2, and the mounting block 202 provides a mounting and fixing point for the air cylinder 203, and the air cylinder 203 can drive the door plate 2 connected with the connecting block to open and close, so that the door plate 2 can be fixed after being opened, improving the operation convenience; the front of the door plate 2 is fixedly installed with a sign 201 for marking the information of the residents; the end of the limiting plate 5 is fixedly installed with an indicator 501 for marking the maintenance time; the sign 201 is used for marking the information of the residents served by the corresponding supporting plate 7, so that the staff can quickly identify the corresponding area of the circuit of different residents, improving the accuracy and efficiency of maintenance and maintenance; the indicator 501 is used for recording and marking the maintenance time of the components, so that the staff can master the maintenance period and arrange subsequent maintenance work in time, ensuring the stable operation of the device.
