An inflatable boat having a polyurea and polyester fiber composite structure
By installing an auxiliary component at the inflation port of the inflatable boat, the problem of air leakage caused by the spring's inability to return after inflation is solved by using the internal pressure difference to assist the spring's rebound. This achieves automatic sealing and efficient inflation of the inflatable boat.

AI Technical Summary
When an inflatable boat is inflated, the spring lacks thrust and cannot rebound properly, leading to air leakage.
An inflatable boat with a composite structure of polyurea and polyester fiber was designed. By setting an auxiliary component at the inflation port, the pressure difference inside the inflatable boat is used to assist the spring rebound. The cooperation of the fixing sleeve, lifting ring, locking block and spring ensures that the seal automatically fits after inflation to prevent air leakage.
It effectively reduces the risk of air leakage caused by spring problems, ensures that the inflatable boat automatically stops taking in air after inflation is complete, and improves inflation efficiency and sealing.
