AI Technical Summary
The buckle structure of existing watertight hatch covers is prone to wear, aging or loosening after long-term use, resulting in a decrease in sealing performance and an increased risk of hatch leakage.
A watertight hatch cover was designed. It consists of a combination of a mounting plate, a hatch cover, a tightening handwheel assembly, a sealing strip, a pressing block, and a sliding pressing assembly. The tightening handwheel drives the pull rod to rotate, and the sliding pressing assembly presses against the pressing block, thus achieving stable pressing of the hatch cover.
It effectively avoids the decline in sealing performance caused by wear and aging, improves the sealing and stability of the hatch cover, and reduces the risk of hatch leakage.
