The invention relates to a combined type sealing device with an automatic inflation and deflation function. The combined type sealing device comprises a combined type sealing assembly and a gas adjusting assembly. The combined type sealing assembly is installed on the frame body and comprises a sealing rubber strip outer bubble and an inflation sealing ring. The center of the sealing rubber strip outer bubble is of a hollow structure, the inflatable sealing ring is inserted into the center of the sealing rubber strip outer bubble, and the sealing rubber strip outer bubble and the inflatable sealing ring form a double-layer composite sealing assembly. Two ends of the sealing rubber strip outer bubble are connected to form an annular sealing ring; the inflation sealing ring is connected with the gas adjusting assembly, and inflation and deflation are conducted through the gas adjusting assembly. Through the double-layer composite sealing assembly, the sealing performance is better, sealing is more reliable, and the effects of shock absorption and sound insulation can be achieved.
