[0012] Furthermore, a hinge is provided between the box body and the box lid, which allows the box lid to be flipped and connected to the box body.

[0013] Compared with existing technologies, this invention offers the following advantages: It provides a waterproof power supply box. A water-retaining groove is provided on the long edge of the lid, recessed inwards to create a height difference with the edge, forming the first layer of waterproofing. A sealing strip is provided on the upper long edge of the box body. When the lid is flipped and fastened to the box body, the sealing strip is pressed against the inner side of the upper long edge of the lid, forming the second layer of waterproofing. A sealing ring is provided inside the lid. When the lid is flipped and fastened to the box body, the sealing ring is pressed against the opening edge of the box body, forming the third layer of waterproofing. These three waterproofing structures ensure the power supply box is waterproof, preventing water ingress. This invention offers superior waterproofing, ingenious design, simple structure, and suitability for mass production. Attached Figure Description
