The guide plate prevents external rainwater from entering the main body and corroding it, thereby improving the ventilation effect.
[0016] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.
[0017] Example 1, by Figures 1-5As can be seen, the aluminum alloy curtain wall with adaptive wind pressure regulating ventilation rate in this case includes a main body 1, with glass 6 attached to the inner wall of the main body 1, and through holes 7 opened on the side of the main body 1. The aluminum alloy curtain wall with adaptive wind pressure regulating ventilation rate also includes an adjusting device 2, a fixing device 3, an installation device 4, and a splicing device 5. The adjusting device 2 is placed inside the through hole 7; the fixing device 3 is sleeved on the outside of the adjusting device 2; the installation device 4 is set on the side of the glass 6 away from the main body 1; and the splicing device 5 is set on the side of the main body 1 away from the installation device 4.

Furthermore, the adjusting device 2 includes an installation cylinder 21, a curved plate 22, an elastic plate 23, a filter screen 24, and a guide plate 25; the installation cylinder 21 is inserted into the inner wall of the through hole 7, and one end is flush with the surface of the main body 1; two curved plates 22 are provided and are respectively fixedly connected to the top and bottom of the inner wall of the installation cylinder 21, and their ends are abutted; the elastic plate 23 is fixedly connected between the curved plate 22 and the installation cylinder 21; the filter screen 24 is provided on the side of the installation cylinder 21 away from the elastic plate 23; the guide plate 25 is provided between the curved plate 22 and the filter screen 24 and is fixedly connected to the inner wall of the installation cylinder 21; wherein, the ventilation rate is adjusted by the installation cylinder 21, the curved plate 22, the elastic plate 23, and the filter screen 24, and the external rainwater is guided by the guide plate 25; In the specific implementation process, it is worth noting that the curved plate 22 is made of FRP (fiberglass reinforced plastic), which has good flexibility, elasticity, and a certain strength, ensuring that the curved plate 22 can deform under wind force and return to its original shape after the wind disappears. The elastic plate 23 is made of PTE thermoplastic elastomer, which combines elasticity and processability. The molecular chain of the elastic plate 23 contains flexible and rigid segments. At low temperatures, the movement of rigid segment molecules is restricted, and the elastic plate 23 becomes hard; at high temperatures, the activity of flexible segments increases, the intermolecular forces weaken, and the elastic plate 23 exhibits softness and elasticity. The filter screen 24 is made of rigid material. Made of woven plastic filaments, the mesh size of the filter screen 24 is not specifically limited, as long as it meets the actual usage requirements.

Furthermore, the fixing device 3 includes a sealing cylinder 32, a fixing plate 33, and a first groove 31; the sealing cylinder 32 is fixedly connected to the outer wall of the mounting cylinder 21 and fits against the inner wall of the through hole 7; the fixing plate 33 is fixedly connected to the end of the mounting cylinder 21 near the filter screen 24, and is fixedly connected to the outer wall of the filter screen 24 and embedded in the surface of the main body 1; two first grooves 31 are provided, and are respectively opened above and below the side of the fixing plate 33 away from the mounting cylinder 21; wherein, the mounting cylinder 21 and the main body 1 are fixed by the sealing cylinder 32 and the fixing plate 33, and the main body 1 and the mounting cylinder 21 are disassembled by the first grooves 31; In the specific implementation process, it is worth noting that the sealing cylinder 32 is made of silicone, which has excellent chemical stability, ensuring that the sealing cylinder 32 can seal the gap between the mounting cylinder 21 and the through hole 7. The operator can pull the mounting cylinder 21 out from the inner wall of the main body 1 through the first groove 31. Through the cooperation between the sealing cylinder 32, the fixing plate 33 and the first groove 31, the mounting cylinder 21 can be quickly disassembled. This is conducive to the operator to quickly clean the filter screen 24 and to quickly replace the curved plate 22 after it has been used for a long time and aged. After the filter screen 24 is cleaned, the mounting cylinder 21 is reinserted into the through hole 7. The sealing cylinder 32 is compressed and fills the gap between the mounting cylinder 21 and the through hole 7, and generates continuous friction to prevent relative sliding between the mounting cylinder 21 and the through hole 7.

The clamping rod structure fits tightly with the second clamping groove 43. The sealing gasket 44 is made of rubber to ensure that the sealing gasket 44 can seal the gap between the main body 1 and the first clamping groove 42 and the second clamping groove 43. Through the cooperation between the splicing plate 41, the first clamping groove 42, the second clamping groove 43 and the sealing gasket 44, the splicing plate 41 and the main body 1 are fixedly connected through the first clamping groove 42 and the second clamping groove 43. First, the glass 6 is placed on the top of the reserved groove of the main body 1. Then, the second clamping groove 43 is inserted into the reserved groove at the bottom of the main body 1.
