[0002] A wind pressing device is installed above the ventilation window of the breeding house. The function of the wind pressing plate of the wind pressing device is to adjust the air inlet angle according to the height and space of different breeding houses, so as to facilitate the outside air to first enter the center of the breeding house and then spread to the surroundings, making the ventilation speed of the breeding house faster and the ventilation effect better; the wind pressing device is a general component. Usually, after the size of the breeding house is determined, when installing the wind pressing device, a smoke test needs to be done to determine the best air inlet angle of the best wind pressing device. Generally, after adjusting the angle, it will not be changed anymore; for the wind pressing plate of the currently used wind pressing device, the rotating shaft at the lower part of the wind pressing plate and the window frame are in interference fit, and the position of the wind pressing plate is fixed by the tension at the rotating shaft at the lower part of the wind pressing plate. There are no fixing parts at the left and right ends of the wind pressing plate. After a long time, due to the aging and deformation of the components, the tension gradually fails, and the wind blocking plate is likely to be not fixed tightly and droops under the action of gravity, thus affecting the ventilation effect.
[0003] Moreover, the current structure of the window sash of the ventilation window of the breeding house is a two-color injection molding structure, which has a complex process and a low yield rate, resulting in a high production cost and needs to be improved. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a wind pressing device and an air inlet window equipped with the wind pressing device. Adjusting plates are arranged on the left and right sides of the air guiding plate to adjust and fix the air guiding plate, making the fixation of the air guiding plate more reliable; the window sash is changed from the original integral two-color injection molding structure, which improves the yield rate of window sash manufacturing and reduces the production cost.
[0005] The utility model includes a wind pressing plate, and the lower part of the wind pressing plate is rotatably connected above the window frame; an adjusting shaft is installed in the wind pressing plate, and the adjusting shaft extends along the length direction of the wind pressing plate, and the left and right ends of the adjusting shaft extend out of the wind pressing plate; adjusting plates are relatively installed on the left and right sides of the window frame, and guiding grooves are arranged on the adjusting plates, and the left and right ends of the adjusting shaft are movably connected in the guiding grooves.
[0006] Preferably, the adjusting plate is a sector centered on the rotation center of the wind pressing plate.
[0007] Preferably, the guiding groove is arc-shaped, and the center line of the guiding groove coincides with the rotation track of the adjusting shaft.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings.
[0025] The orientations involved in this specification are based on the orientations when a kind of air pressure device of the present utility model and an air inlet window equipped with the air pressure device are working properly, without limiting their orientations during storage and transportation, only representing relative positional relationships and not absolute positional relationships.
[0026] As Figures 1 to 5 As shown together, a kind of air pressure device is installed above the window opening of the air inlet window and is used in cooperation with the window sash 8 to adjust the air inlet angle of the window opening of the air inlet window, so as to make the ventilation effect of the breeding house better; it includes an air pressure plate 1, a rotating shaft is provided at the lower part of the air pressure plate 1, and the rotating shaft is rotatably connected above the window frame; an adjusting shaft 2 is installed in the air pressure plate 1, the adjusting shaft 2 is arranged in the upper middle part of the air pressure plate 1, the adjusting shaft 2 extends along the length direction of the air pressure plate 1, the adjusting shaft 2 passes through the plate body of the air pressure plate 1, and the left and right ends of the adjusting shaft 2 extend out of the air pressure plate 1.
[0027] Adjusting plates 3 are relatively installed on the left and right sides of the window frame. The adjusting plates 3 are sectors centered on the rotation center of the air pressure plate 1, which can well cooperate with the rotation contour of the outer edge of the air pressure plate 1, with beautiful appearance and reasonable structure; guiding grooves 4 are provided on the adjusting plates 3, and the guiding grooves 4 penetrate through the plate surface of the adjusting plates 3. The left and right ends of the adjusting shaft 2 are movably connected in the guiding grooves 4; the guiding grooves 4 are arc-shaped, and the center line of the guiding grooves 4 coincides with the rotation track of the adjusting shaft 2. When the adjusting shaft 2 rotates following the air pressure plate 1, the end of the adjusting shaft 2 moves in the guiding grooves 4; limiting convex ribs 5 are arranged at intervals on the inner side of the adjusting plates 3. The limiting convex ribs 5 are small convex blocks protruding outside the adjusting plates 3. The limiting convex ribs 5 are arranged in an arc centered on the rotation axis of the air pressure plate 1, and the distance between adjacent two convex ribs is adapted to the thickness of the air pressure plate 1; the limiting convex ribs 5 are arranged at the edge of the guiding grooves 4, and there are two rows of limiting convex ribs 5, which are distributed on the inner and outer sides of the guiding grooves 4. When the air pressure plate 1 is adjusted to an appropriate angle, the air pressure plate 1 is stuck between two adjacent limiting convex ribs 5 to further prevent its movement.
[0028] A tightening nut 6 is installed at the end of the adjusting shaft 2, which is located outside the adjusting plate 3. After the air pressure plate 1 is adjusted to the proper position, the tightening nut 6 is tightened to fix the air pressure plate 1 at the corresponding position on the adjusting plate 3 to prevent its movement.
[0029] As Figure 1 、Figure 4 , Figure 5 and Figure 6 As shown in Figure 4 , Figure 5 and Figure 6 , an air inlet window is provided with a blast air device as described above. A blast air device is installed above the window of the air inlet window. A window sash 8 is installed inside the window of the air inlet window. A rotating shaft is provided at the lower part of the window sash 8. The window sash 8 can rotate around the rotating shaft to realize the opening and closing of the window. The window sash 8 includes a window sash main body 801 at the lower part and a window bar 802 installed on the upper part of the window sash main body 801. The window sash 8 is changed from the original two-color injection molding structure to the current upper and lower two parts, which are separately manufactured. The lower part uses single-color injection molding, and the upper part is an independent window bar 802, which improves the yield rate of manufacturing the window sash 8 and reduces the production cost.
[0030] Furthermore, the upper part of the window bar 802 is in an arc structure. The window bar 802 is made of silicone material. The upper part of the original window sash 8 was straight. When the window sash 8 was closed, the upper part directly contacted the window frame, which easily led to poor sealing. Now the window bar 802 is changed to an arc structure. During the process of closing the window sash 8, the edge of the arc-structured window bar 802 gradually contacts the window frame from top to bottom in sequence, which has a pre-pressing effect on the window bar 802 and makes the sealing better.
[0031] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
