The receiving walls 12 are all interference fit, so when in use, the waterproof box body 1 and the box cover 2 can clamp the elastic sealing ring 3 after assembly. The elastic sealing ring 3 is squeezed and deformed after assembly to prevent rainwater from penetrating into the interior from the assembly surface. The elastic sealing ring 3 and the card slot 20 and the surrounding receiving wall 12 are all interference fit, so an elastic sealing ring 3 is provided at the installation opening, and sealing rings are provided between the inner wall of the card slot 20 and the outer wall of the surrounding receiving wall 12 and between the inner wall of the card slot 20 and the inner wall of the surrounding receiving wall 12 for elastic sealing. In this way, rainwater cannot enter the interior of the shell, and the circuit board will not be exposed to rainwater, thereby playing a role in waterproofing and moisture-proofing, and the structure is simple, and no additional multi-layer waterproof layer is required.
