Self-telescopic high-frequency long-life gas spring

The utility model provides a self-telescopic high-frequency long-service-life gas spring, and belongs to the technical field of gas springs. Comprising an outer pipe, a piston rod is arranged at one end of the outer pipe, a base is arranged at the other end of the outer pipe, a piston is arranged in the outer pipe, one end of the piston penetrates through the outer pipe to enter the outer pipe, a piston is arranged in the outer pipe, and one end of the piston is connected with the piston rod. By arranging the double-air-pressure oil seal and the single-oil-pressure oil seal, the air spring is different from a free telescopic air spring of an existing single-air-pressure oil seal or an existing double-air-pressure oil seal in the market, the air spring can be suitable for high-frequency telescopic operation, and the problems that an existing air pressure rod is low in frequency and short in service life are solved. The service life is directly prolonged to more than 7 million, the pneumatic rod is suitable for
