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
Technical Problem
When an inflatable boat is inflated, the spring lacks thrust and cannot rebound properly, leading to air leakage.
Method used
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.
Benefits of technology
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.

Abstract
The utility model relates to the technical field of inflatable boats, disclose a kind of inflatable boat with polyurea and polyester fiber composite structure, including main component, including inflatable boat, inflatable boat is provided with inflation port, the inflation port includes interface main body, interface main body side is provided with sealing cover, sealing cover side is fixed with mobile column, mobile column side is provided with first spring;Auxiliary assembly is located in the interface main body, including auxiliary part, the fixed sleeve that the auxiliary part includes is fixed in the interface main body, lifting ring is slidably arranged in the fixed sleeve.The utility model has beneficial effect that: the pressure difference before and after the utility model uses inflatable boat inflation is used to assist spring rebound, when inflating is completed and air nozzle is pulled out, the high pressure in the body will generate the outward thrust to sealing element, and the resultant force is formed with spring rebound force, to reduce the air leakage risk caused by spring problem, and when inflatable boat reaches certain pressure after inflation, will automatically stop air intake.
