[0026] Example 1:

[0027] like Figure 1-3 As shown, a ventilation device with universal adjustment function includes a frame 1 fixed to the bulkhead. The top of the frame 1 is provided with a ventilation chamber 3. Several profiles 18 are evenly distributed in the ventilation chamber 3, and the profiles 18 divide the ventilation chamber 3 into several ventilation openings. Blades 5 are provided at the ventilation openings. The top two sides of the blades 5 are respectively hinged to the two side walls of the ventilation chamber 3, and the bottom two sides of the blades 5 are respectively hinged to two push rods 16. The push rods 16 are hinged to a drive plate 6. The bottom of the frame 1 is provided with a transmission chamber 4. The transmission chamber 4 is provided with a transmission unit. An opening and closing assembly is provided below the transmission unit. The opening and closing assembly drives the drive plate 6 to rise and fall through the transmission unit.

[0028] like Figure 4 As shown, the opening and closing assembly includes a handwheel box 11, which is fixed to the bulkhead. The handwheel box 11 contains two meshing bevel gears 22, which are sleeved on one end of a rotating shaft 23. One of the rotating shafts 23 is fixed to the handwheel 12, and the other rotating shaft 23 is connected to a connecting rod 10 through a universal joint 9. The connecting rod 10 is connected to the transmission unit through the universal joint 9.

[0029] During installation, select a suitable length of connecting rod 10 based on the installation height of frame 1. Simply fix frame 1 to the mounting holes on the bulkhead and select the installation position of handwheel box 11 according to different cabin layouts. When opening, the crew only needs to rotate handwheel 12, which, through the transmission of bevel gear 22, universal head 9 and connecting rod 10, causes worm gear 8 to rotate, driving worm wheel 21 and main shaft 7 to rotate, thereby causing swing arm 20 to swing linearly, driving top rod 19 to lift, thus raising drive plate 6, thereby lifting blade 5 and opening the vent. When closing, the crew only needs to rotate handwheel 12 in the opposite direction, which, through the transmission of bevel gear 22, universal head 9 and connecting rod 10, causes worm gear 8 to rotate in the opposite direction, driving worm wheel 21 and main shaft 7 to rotate, thereby causing swing arm 20 to swing downward, driving top rod 19 to pull down, thus moving drive plate 6 downward, thereby pressing down blade 5 and closing the vent. Moreover, due to the self-locking action of worm wheel 21 and worm gear 8, blade 5 will not change position.

[0030] The ventilation device with universal adjustment function in this embodiment adopts an external opening and closing assembly, which allows the crew to open and close the ventilation device without the need for a ladder. The opening and closing is quick, and the opening and closing assembly allows the crew to adjust the opening angle of the blades 5 according to the ventilation volume requirements. The operation is precise and convenient. In addition, the opening and closing assembly uses a universal head 9 and a connecting rod 10 to connect the handwheel box 11 and the transmission unit, so that the handwheel box 11 can be installed in different cabin layouts, which is more flexible.

[0031] The frame 1 is provided with lifting lugs 2 on both sides of the top; the lifting lugs 2 are provided to facilitate the hoisting of the entire ventilation device and facilitate installation.

[0032] The transmission unit includes a main shaft 7 rotatably connected to the transmission chamber 4. A worm gear 21 is sleeved at the end of the main shaft 7. The worm gear 21 is threadedly engaged with a worm 8. The worm 8 is rotatably connected to the bottom of the transmission chamber 4 and connected to a connecting rod 10 via a universal joint 9. Both ends of the main shaft 7 are fixed with swing arms 20. The end of the swing arm 20 is hinged to one end of a top rod 19, and the other end of the top rod 19 is hinged to the bottom end of the drive plate 6. The worm 8 is driven by the connecting rod 10, which drives the worm gear 21 and the main shaft 7 to rotate, thereby causing the swing arm 20 to swing, driving the top rod 19 to rise or fall, thus realizing the raising and lowering of the drive plate 6.

[0033] The ventilation chamber is equipped with a mesh 13 on the side away from the cabin wall; the mesh 13 serves as a filter to prevent foreign objects from entering the cabin.

[0034] The ventilation opening is provided with protruding plates on all four sides facing the outside of the cabin. Several blades 5 are evenly distributed in the ventilation chamber 3. Each blade 5 is provided with a groove around the protruding plate. A sealing gasket 17 is provided in the groove. The sealing gasket 17 seals the gap between the protruding plate and the groove to prevent rainwater from entering the cabin and improves the sealing performance between the blade 5 and the ventilation opening.

[0035] The drive plate 6 is provided with a slide groove 14, and a limiting pin 15 is slidably engaged in the slide groove 14. The limiting pin 15 is fixed to the side walls of the ventilation chamber. The slide groove 14 and the limiting pin 15 are provided to guide the drive plate 6 to move only up and down, so as to ensure the smooth opening and closing of the push blade 5.

[0036] The frame 1 is provided with mounting plates 24 on all four sides. The mounting plates 24 are welded to the outside of the bulkhead. The mounting plates 24 have screw holes, and the frame 1 is fixed to the bulkhead by bolts.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
