The core technology of European-style waterproof box design is based on sealing and leak-proof techniques to prevent moisture and other external substances from entering the interior, protecting the contents. Common technologies include rubber sealing rings, leak-proof strips, and waterproof screws. In terms of material selection, the outer shell material must possess properties such as corrosion resistance, high-temperature resistance, low-temperature resistance, and impact resistance, while internal components such as gaskets and sealing rings require good flexibility, wear resistance, and corrosion resistance. Key elements of the structural design include the lid, sealing ring, switch, and fixing device; a reasonable design can effectively enhance waterproof performance.
The design includes an upper lid and a lower shell, with a waterproof component installed on the inside of the lower shell. The waterproof component consists of a sealing part and a gap part. The sealing part fits snugly against the inner wall of the lower shell, while the gap part forms a sealant groove between itself and the inner wall. When the upper lid and lower shell are assembled, the lower end of the upper lid enters the sealant groove, allowing the sealant in the groove to completely fill the gap, ensuring a complete seal between the upper lid and the lower shell, thus solving the problem of gaps easily created by screw fixing.
