[0002] The low voltage meter box is an important part of the electric energy metering in the power system. In the electric energy metering, the low voltage meter box is an instrument used to measure and manage the low voltage electricity.

[0003] When installing a low-voltage meter box outdoors, the low-voltage meter box is subjected to the natural sun, wind, rain, and especially lightning for a long time. The non-metallic meter box is a new type of electrical equipment box, mainly made of polymer materials. Compared with traditional metal meter boxes, non-metallic meter boxes have better corrosion resistance, heat resistance, weather resistance and other characteristics, so the use of non-metallic meter boxes outdoors is becoming more and more widespread; but with the increase in usage time, the fixings of the meter box become loose, causing the meter box to tilt to one side. When it rains, due to the tilt of the meter box surface, rainwater can easily enter the interior of the meter box through the heat dissipation grooves on the side walls of the meter box, causing water accumulation inside the meter box and moisture inside the meter box, thereby affecting the operation of electrical components inside the meter box.

[0004] Therefore, it is necessary to provide a new non-metallic low-pressure metering box to solve the above-mentioned technical problems. Utility Model Content
