As shown in fig. 1 to 4, the ventilation window structure of the present solution can be used in a greenhouse shed, a warehouse, a farm, and other places, and the following is a detailed explanation of the case of being applied to the greenhouse shed:

a louver assembly comprising: the air conditioner comprises a main body 1, a ventilation window 2, a gear 3, a driving piece 4, a rack 42 arranged on the driving piece 4 and a limiting mechanism 5. Wherein, in the main body 1, the ventilating window 2 and the rotating shaft 20, a ventilating opening 10 is arranged on the main body 1; the ventilating window 2 is hinged on the main body 1 through the rotating shaft 20 and is positioned at the ventilating opening 10, and the ventilating window 2 can rotate to block the ventilating opening 10; the gear 3 is sleeved on the rotating shaft 20, and the gear 3 can drive the rotating shaft 20 to rotate so as to open or close the ventilation window 2; and the driving part 4 is used for driving the gear 3, a rack 42 is arranged on the driving part 4, and the rack 42 is meshed with the gear 3. Specifically, in the scheme, the main body 1 mainly refers to a greenhouse body of the greenhouse; the driving member 4 comprises a piston cylinder 40 and a piston rod 41 arranged in the piston cylinder 40, and the rack 42 is arranged on the piston rod 41. The piston cylinder 40 is generally communicated with fluid, and the piston rod 41 is pushed by the fluid to move telescopically, so that the rack 42 and the gear 3 are driven to be meshed for transmission, and the ventilation window is opened. One end of the ventilating window 2 protrudes from the limiting piece 21, when the ventilating window 2 blocks the ventilating opening 10, the limiting piece 21 is abutted to the main body 1, the limiting piece 21 is arranged, when the ventilating window 2 is completely closed, the ventilating window 2 is prevented from continuously moving towards the direction of closing the ventilating window, and the blocking effect of the ventilating window 2 is ensured.
