[0003] The patent document with application number CN220021941U discloses a waterproof structure of a distribution cabinet, which relates to the field of distribution cabinets, including a front cover plate of a distribution cabinet and a distribution cabinet shell. The front cover plate of the distribution cabinet includes a front cover plate body, a first thread groove and an inner concave groove. A through opening is provided on the surface of the front cover plate body. The openings are provided in four groups and are evenly arranged at the four corners of the surface of the front cover plate body. The first thread groove is fixedly connected in each group of openings. An inner concave groove is provided on the surface of the front cover plate body. The distribution cabinet shell includes a shell body, a second thread groove and a protruding connecting piece. A second opening is provided on the surface of the shell body. The second openings are provided in four groups and are evenly arranged around the surface of the shell body. In this waterproof structure of the distribution cabinet, the front cover plate of the distribution cabinet and the distribution cabinet shell are fixed by four groups of bolts. When the distribution cabinet is fixed by bolts, grooves and protrusions are provided inside, which correspond to each other, thereby reducing the possibility of rainwater flowing into the distribution cabinet through the gap and enhancing the overall waterproofness.
