The invention relates to the field of earthquake-avoiding equipment, in particular to a buffering structure of an earthquake-avoiding safety cabin. The buffering structure comprises a bottom plate and a top plate, wherein two fixing seats are arranged on the bottom plate, a sliding rail rod is connected between the fixing seats, gas springs are fixedly connected to the fixing seats, the top plate is positioned above the bottom plate, the bottom of the top plate is fixedly connected with the top ends of the gas springs, a safety cabin is arranged on the top plate, a roof is arranged at the top of the safety cabin, first spring seats are arranged on the inner walls of the two sides of the roof, second spring seats are arranged above the inner walls of the two sides of the safety cabin, and retaining rings are arranged on the first spring seats and the second spring seats. When the top plate vibrates up and down, rotating rods are driven to rotate, the rotating rods drive sliding sleeves to slightly slide, telescopic springs can provide certain elastic force and buffering force, enough buffering force is guaranteed for mounting plates, the gas springs also play a certain damping role, and therefore, strong vibration of the safety cabin is effectively reduced.
