The movable rack 600 and the movable door 700 may be fixedly connected by welding or bolts, so as to drive the movable door 700 to move in a translational motion. Since the gear rotates while performing the translational motion, when the linear cylinder 500 moves to the maximum stroke, the movable rack 600 drives the movable door 700 to move by a distance greater than the stroke of the linear cylinder 500. Since the movement distance superimposed on the fixed rack gear 200 is a movement distance during the rotation of the gears, the moving door 700 moves a distance 2 times as long as the moving stroke of the linear cylinder 500 when the diameters of the driving end gear 303 and the driven end gear 306 are the same.
Embodiment 2, the utility model discloses a work process of the pneumatic sliding door translation of rack and pinion formula enlargies stroke mechanism is as follows: when the gear assembly fixing rack works, after receiving an instruction of a control system, a driving system can drive the linear air cylinder 500 to act, the lever of the linear air cylinder 500 pushes the gear assembly fixing rack 400, and the gear assembly fixing rack 400 moves and simultaneously drives the driving end gear 303 meshed with the fixed rack 200 to move and rotate under the action of the fixed rack 200. The driving end gear 303 rotates and simultaneously drives the driven end gear 306 to synchronously rotate, and the driven end gear 306 is meshed with the movable rack 600 to drive the movable rack 600 to move. The movable rack 600 and the movable door 700 may be fixedly connected by welding or bolts, so as to drive the movable door 700 to move in a translational motion. Since the gear rotates while performing the translational motion, when the linear cylinder 500 moves to the maximum stroke, the movable rack 600 drives the movable door 700 to move by a distance greater than the stroke of the linear cylinder 500. The diameter of the driving end gear 303 is smaller than that of the driven end gear 306, so that the circumference of the driving end gear 303 is smaller than that of the driven end gear 306, and when the driving end gear 303 and the driven end gear 306 coaxially and synchronously rotate, the movement strokes of the racks respectively engaged with the driving end gear 303 and the driven end gear 306 are different, so that the moving distance of the movable door 700 is greater than 2 times of the movement stroke of the linear cylinder 500.
