The invention discloses a composite material air cylinder inner container sealing structure, an air cylinder and a railway vehicle, the composite material air cylinder inner container sealing structure comprises a flange plate base and a threaded seat, and a sealing joint is arranged to be of a split structure of the flange plate base and the threaded seat. The flange plate base is connected with the inner container and serves as a bearing transition piece. Mechanical connection and glue joint are matched for use, a large area of the bottom of the flange plate base is glued, a glue layer is uniform, the thickness is guaranteed, and then the flange plate base is connected with threads of the inner container in a matched mode. The sealing reliability is achieved through the mechanical connection mode, the glue layer provides part of strength, meanwhile, buffering between the flange plate base and the inner container is achieved, and thermal expansion and cold contraction are compensated. 本发明公开了一种复合材料风缸内胆密封结构及风缸
