AI Technical Summary
Existing bags are prone to corrosion at the bottom when used in waterlogged environments, which shortens their lifespan.
A corrosion-resistant bag was designed, with a frame and base made of corrosion-resistant engineering plastic. It combines a block and slot structure, and uses springs and sealing rings to achieve a stable connection and seal, preventing water accumulation and corrosion.
It effectively prevents water splashing from the road surface, improves the corrosion resistance of bags and luggage, extends their service life, and is easy to install and disassemble, enhancing overall strength and stability.
