The invention provides a ventilation window adjusting device and an animal house ventilation adjusting assembly, the ventilation window adjusting device comprises a hollow shaft, a first wheel, a second wheel and an anti-reversion structure, and the hollow shaft is provided with a first shaft section and a second shaft section in the axial direction; the first wheel sleeves the first shaft section; the second wheel is used for winding a pull rope connected with the ventilation window, the second shaft section is sleeved with the second wheel in a sliding mode, the second wheel has a first rotating direction and a second rotating direction relative to the second shaft section, and the first rotating direction is opposite to the second rotating direction; the anti-reversion structure has an engaged state and a disengaged state; when the anti-reversion structure is in the engaged state, the second wheel is engaged with the first wheel and is limited to rotate around the hollow shaft in the first rotating direction; and when the anti-reversion structure is in the disengaged state, the second wheel is disengaged from the first wheel and can rotate around the hollow shaft in the second rotating direction. According to the ventilation window, winding and unwinding of the pull rope can be conveniently adjusted, so that the ventilation window is adjusted, adjustment is convenient and reliable, and the labor intensity of workers is also reduced.

    本公开提供一种通风窗调节装置及动物圈舍通风调节组件,包括空心轴、第一轮、第二轮以及防逆转结构,空心轴沿轴向上具有第一轴段和第二轴段;第一轮套设在第一轴段上;第二轮用于绕设与通风窗连接的拉绳,第二轮滑动套设在第二轴段上相对第二轴段具有第一转动方向及第二转动方向,第一转动方向与第二转动方向相反;防逆转结构具有啮合状态和脱离状态;在防逆转结构处于啮合状态时,第二轮与第一轮相啮合且被限定为绕空心轴沿第一转动方向旋转;在防逆转结构处于脱离状态时,第二轮与第一轮脱离能够绕空心轴沿第二转动方向旋转。本公开能方便地能调节拉绳的收放,从而对通风窗进行调节,调节方便可靠,也降低了工人的劳动强度。
