The invention, which relates to the technical field of ventilation equipment, discloses a connecting structure of an air duct and a ventilation belt and an air duct system. The connecting structure comprises an air duct, a ventilation belt, a fixing piece, an annular soft sleeve and an elastic band. The fixing piece is fixedly connected to the air duct; the fixing piece is connected with the annular soft sleeve; the annular soft sleeve is close to an air opening of the air duct and surrounds the outer side of the air duct, an annular gap for the ventilation belt to penetrate through is reserved between the annular soft sleeve and the outer wall of the air duct, and the elastic band is connected with the annular soft sleeve. When the elastic band is loosened or tensioned, the width of the annular gap can be increased or decreased. According to the connecting structure of the air duct and the ventilation belt and the air duct system, the structure is simple, a worker can conveniently andrapidly disassemble and assemble the ventilation belt on the air duct, and the structure of the ventilation belt cannot be damaged.
