Balloon in-air releasing device enabling balloon to bear straightening impact

The utility model discloses a balloon in-air releasing device enabling a balloon to bear the straightening impact. The device comprises an upper hanging ribbon, a central hanging ribbon, a balloon body and a lower hanging ribbon, wherein the upper hanging ribbon and the lower hanging ribbon are respectively connected to the two ends of an external unfolding releasing device; the central hanging ribbon is mounted between the upper end face and the lower end face of the inner part of the balloon body along the central axis of the balloon body in a tearing ribbon manner. According to the utility model, during the balloon straightening process, the force transmission path of the balloon during the in-air straightening process is changed through the adoption of the structural design of the balloon central hanging ribbon, so that the balloon skin is prevented from bearing the impact; besides, the central ribbon adopts a tearing ribbon design, so that the relative speed between an upper cabin section and a lower cabin section during the balloon straightening process is reduced, and accordingly, the impact at the straining moment is reduced; therefore, the damage of the balloon during the straightening process is avoided.
