[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1-10 , the utility model provides a technical solution:

[0036] An aluminum alloy damper with co-rotating blades comprises a damper housing 1, a plurality of aluminum alloy blades 2 equidistantly arranged within the damper housing 1, and a transmission assembly 3 for coordinating the rotation of the aluminum alloy blades 2. The aluminum alloy blades 2 have an elliptical cross-section and a cavity 5 formed therein. Blade plugs 4 are provided at each end of the aluminum alloy blades 2, and sealing strips 6 are provided on both sides of the aluminum alloy blades 2 to overlap with the brackets of the aluminum alloy blades 2 to maintain a seal.

[0037] The transmission assembly 3 is fixed on the vertical aluminum profiles 7 on both sides of the air valve housing 1, and the two ends of several aluminum alloy blades 2 are connected to the transmission assembly 3 through the middle of the blade plug 4, and the aluminum alloy blades 2 are rotated and opened and closed through the transmission assembly 3.

[0038] like Figure 2As shown, the damper housing 1 includes two vertical aluminum profiles 7 and two horizontal aluminum profiles 8. The cross section of the vertical aluminum profile 7 is I-shaped, and a limit plate 9 is provided on both sides of the vertical aluminum profile 7. The fixed side plates 10 with the same number of aluminum alloy blades 2 are clamped through the inner grooves of the limit plates 9. A gear installation space 11 is formed between the fixed side plates 10 and the vertical aluminum profile 7.

[0039] The two ends of the two horizontal aluminum profiles 8 and the two ends of the two vertical aluminum profiles 7 are fixed in a rectangular shape by screws. The two ends of one horizontal aluminum profile 8 are fixed to the top ends of the two vertical aluminum profiles 7 by screws, and the two ends of the other horizontal aluminum profile 8 are fixed to the bottom ends of the two vertical aluminum profiles 7 by screws.

[0040] The middle of the inner side of the two horizontal aluminum profiles 8 are respectively provided with arc-shaped raised rubber strips 12. When the aluminum alloy blades 2 located at the top and bottom ends of the inner side of the air valve housing 1 are closed, the rubber strips 12 cooperate with the sealing strips 6 on the aluminum alloy blades 2 to maintain the sealing effect of the ventilation system.

[0041] The transmission assembly 3 includes a driving gear 14, a control plate 13 that cooperates with the driving gear 14, and a transmission gear 15 that meshes with the outer side of the driving gear 14. The axis of the driving gear 14 is connected to the control plate 13 via an aluminum square shaft 16, and the end of the aluminum square shaft 16 passes through the fixed side plate 10 and is fixed to the corresponding blade plug 4.

[0042] The outer side of the transmission gear 15 is meshed with a rotating gear 17, and the axis of the transmission gear 15 is fixedly connected to the middle of the corresponding blade plug 4 through the connecting square shaft 18. A manual actuator is provided on the control panel 13 and connected to the aluminum square shaft 16, which is used to drive the aluminum square shaft 16. The rotating aluminum square shaft 16 is used to transmit the driving gear 14, and then the rotational force is transmitted to the rotating gear 17 through the transmission gear 15 meshing with the driving gear 14.

[0043] The driving gear 14, the transmission gear 15 and the rotating gear 17 are respectively arranged in the gear installation space 11;

[0044] The axis of the transmission gear 15 is respectively arranged on the gear base 19 between the two fixed side plates 10 and rotates in conjunction with the gear base 19. The gear base 19 maintains the stability of the driving gear 14 transmitting the transmission gear 15 and the transmission gear 15 cooperating with the rotating gear 17.

[0045] like Figure 10 As shown, vertical reinforcing ribs 20 are provided in the cavity 5 , and the reinforcing ribs 20 are used to increase the deformation resistance stress of the aluminum alloy blade 2 .

[0046] A clamping block 21 is provided on the inner side of the blade plug 4 and is inserted into the cavity 5 to fix the blade plug 4 . The clamping block 21 cooperates with the blade plug 4 to quickly assemble with both ends of the aluminum alloy blade 2 .

[0048] The blades rotate in the same direction as the aluminum alloy air valve. The cross section of the aluminum alloy blade 2 is elliptical, which reduces the aluminum alloy blade 4 to reduce the resistance of the wind flow through the ventilation system. A cavity 5 is set inside the aluminum alloy blade 4 to reduce the manufacturing cost of the aluminum alloy blade 4 while reducing the weight of the aluminum alloy blade 4. Blade plugs 4 are set at both ends of the aluminum alloy blade 2, and sealing strips 6 are set on both sides of the aluminum alloy blade 2. When the transmission component 3 rotates to cooperate with the aluminum alloy blade 2 to open or close, the sealing strip 6 at the bottom edge of the upper aluminum alloy blade 2 and the lower aluminum alloy blade 2 are sealed. The sealing strips 6 on the top edge are overlapped, thereby realizing the overlap between the aluminum alloy blades 2 by using the sealing strips 6. After the aluminum alloy blades 2 are closed, as the transmission component 3 continues to transmit, the sealing strips 6 on both sides of the aluminum alloy blades 2 are pressed tightly as the transmission component 3 continues to transmit, and soft glue 22 is set on the outside of the blade plugs 4 at both ends of the aluminum alloy blades 2. When the aluminum alloy blades 2 are closed, the soft glue 22 on the outside of the blade plugs 4 is tightly attached to the inner side of the side panel, thereby ensuring the closure of the two ends of the aluminum alloy blades 2 and ensuring the sealing effect of the ventilation system when the aluminum alloy blades 2 are closed.
