The two limiting guide rails 200 are symmetrically arranged along the left-right direction, and the limiting guide rails 200 extend along the up-down direction. A limiting groove 210 is provided in the limiting guide rail 200, and the openings of the limiting grooves 210 of the two limiting guide rails 200 face away from each other, that is, the opening of the limiting groove 210 of the limiting guide rail 200 on the left side faces left, and the opening of the limiting groove 210 of the limiting guide rail 200 on the right side faces right. The left and right sides of the rolling door assembly 100 are respectively inserted into the two limiting guide rails 200, and the rolling door assembly 100 can move in the up-down direction. A plurality of limiting buckles 300 are fixedly installed on both sides of the rolling door assembly 100, and the plurality of limiting buckles 300 on the same side are arranged at intervals in the up-down direction. The limiting buckle 300 is located in the limiting guide rail 200 , and the second hook portion 320 of the limiting buckle 300 is inserted into the limiting groove 210 to limit the rolling door assembly 100 from moving in the left and right directions.
