Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, and in particular relates to a metering box which is easy to install and disassemble. Background Art

[0002] A meter box is a device used to meter and measure electrical energy. It is currently widely used in residential, commercial or industrial places. Depending on the application site, the design of the meter box also needs to change accordingly.

[0003] The meter box includes a box body, in which an electric energy metering device, usually an electric energy meter, is installed. A threaded connector is provided on the back of the box body, and the box body can be detachably mounted to a wall or other supporting component through the threaded connector. When a serious fault occurs inside the meter box, the threaded connector can be removed to remove the entire box body from the supporting component.

[0004] When a computer meter and other related components have been installed in the box, the components in the box need to be removed first before the threaded connectors can be removed. This is because the weight of the meter box will be applied to the threaded connectors, affecting their normal rotation, which increases the workload of the operator in removing the box from the supporting components. Similarly, when installing the box back into the supporting components, the box needs to be kept in an empty state to successfully install the threaded fasteners, which increases the workload of installing the box on the supporting components. In addition, even if the box is in an empty state, the operator still needs to hold the box when installing the threaded fasteners to prevent its installation from shifting, which is more inconvenient. Summary of the Invention
