In this process, the push plate 8 is driven by the rolling shutter body 5 to contact the top of the connecting plate 13, and the connecting plate 13 pushes the piston 10 on the piston rod 11 to move inside the piston tube 9 during the movement, so that the gas inside the piston tube 9 is pressed into the long gas through the connecting pipe 14. Inside the pad 7, when the roller shutter body 5 moves to the ground, the long air cushion 7 contacts the ground, thereby improving the sealing of the roller shutter door. At the same time, the sealing strip 16 contacts the outside of the roller shutter body 5, which can seal both sides of the roller shutter body 5; when the roller shutter body 5 rises, the push plate 8 separates from the top of the connecting plate 13. At this time, the gas inside the long air cushion 7 will enter the interior of the piston cylinder 9, and the gas will push the piston 10 to move inside the piston cylinder 9, thereby driving the piston rod 11 to reset, which is convenient for the curling and resetting of the roller shutter body 5.
