Fully-formed fabric reinforced air column and flexible cabin

The utility model relates to the technical field of high-pressure inflatable flexible cabins, in particular to a flexible cabin formed by fully-formed fabric reinforced arched/annular air columns and air column supports, which comprises a three-dimensional cylindrical fabric reinforced body and an airtight cylindrical film arranged inside the three-dimensional cylindrical fabric reinforced body. The three-dimensional cylindrical fabric reinforcement and the three-dimensional cylindrical fabric reinforcement are bonded into a whole; internal airtight seals are welded to the two ends of the airtight cylinder film, and external fabric seals are sewn to the two ends of the three-dimensional cylindrical fabric reinforcement. The three-dimensional cylindrical fabric reinforcing body is a continuous integrated product, the two ends of the three-dimensional cylindrical fabric reinforcing body are sealed, bonding or sewing joints do not exist, the performance weak ring of the product is reduced, the air column can bea
