This electric meter box plays an indispensable role in the stable operation of the power system, the energy efficiency management of industrial production, and the refined management of commercial electricity consumption. Especially in large office buildings, commercial complexes, and industrial manufacturing fields, its ability to accurately measure and monitor power consumption is particularly important.

[0003] In related technologies, an electric meter box includes a box body, a box door installed on the box body, and electrical components installed inside the box body. The electrical components include an electric meter, a current transformer, a molded case circuit breaker, and related cables, etc.; the current transformer is the core component of the electric meter box, which can convert the measurement of high voltage and large current into a safe signal of low voltage and low current, facilitating the processing of subsequent equipment; the electric meter is used to display and record the power consumption situation.

[0004] According to the typical design requirements of the State Grid, the installation position of the electric meter box should be no less than 180 centimeters above the ground to ensure operation safety and avoid the risk of accidental touch. Although this height requirement is reasonable, it brings inconvenience during regular maintenance by staff; since various tools often need to be carried during the maintenance process, and due to physical limitations of the staff, it is difficult to carry all the necessary tools at the same time. Therefore, they have to place the temporarily unused tools on the ground and climb up and down to retrieve them when needed. This process is not only cumbersome and inefficient but also may increase potential safety hazards, leaving room for improvement. Summary of the Invention
