Quickly-mounted pressure-resistant air door

The utility model relates to a coal mine air door, particularly to a quickly-mounted pressure-resistant air door, which solves the technical problem that the existing air door is easy to damage in case of roadway deformation, and includes an outer frame, an inner frame and two door leaves mounted in the inner frame, wherein a buffering part is arranged between the outer frame and the inner frame; a reverse air preventing baffle plate is arranged at the rotating shaft part of the inner frame; a buffering cushion is arranged on the reverse air preventing baffle plate; and a mechanical reverse-push connecting rod is connected between the door leaves. Compared with the existing air door, the quickly-mounted pressure-resistant air door has excellent pressure property produced in resisting the roadway deformation, and enhances the shock resistance of the door leaves by hitting the anchor rod into the coal layer to fix the door.
