[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] like Figures 1 to 13 As shown, a ventilation and soundproof louver includes:

[0048] The frame 1 includes two parallel vertical tubes, the upper and lower ends of which are connected by horizontal tubes 102; the louver slats include two louver blades 2, one side of which is hinged to the other side of which is hinged by a hinge shaft 202, the hinge shaft 202 being rotatably connected to the vertical tubes; the number of louver slats is multiple, and the multiple louver slats are evenly arranged along the height direction; the drive assembly is used to drive the hinge shaft 202 to rotate.

[0049] The length of louver 2 is greater than the spacing between adjacent louver slats.

[0050] A hinge shaft 202 is fixed at one end of the side of the louver, and an installation tube 201 is fixed at the other end.

[0051] The hinge shaft 202 of one of the louvers 2 is located in the mounting tube 201 of the other louver 2;

[0052] The hinge shafts 202 of the two louver blades 2 are arranged coaxially, and there is a gap between the hinge shafts 202 of the two louver blades 2. A positioning groove 204 is opened on the end face of the hinge shaft 202 of the louver blade 2 near the mounting ring. A connecting post 4 is provided between the hinge shafts 202 of the two louver blades 2. Positioning posts corresponding to the positioning groove 204 are fixed at both ends of the connecting post 4. The positioning posts are located inside the positioning groove 204.

[0053] The horizontal tube 102 is a rectangular tube;

[0054] The vertical tube includes a U-shaped plate 101 and a cover plate 103, wherein the cover plate 103 closes the side opening of the U-shaped plate 101 to form a rectangular tube;

[0055] The vertical pipe and the horizontal pipe 102 are connected by an L-shaped connector, with one end of the L-shaped connector located inside the horizontal pipe 102 and the other end located inside the vertical pipe.

[0056] A baffle 7 corresponding to the louver slats is fixedly provided on the lower end surface of the upper horizontal tube 102; a baffle 7 corresponding to the louver slats is fixedly provided on the upper end surface of the lower horizontal tube 102.

[0057] In some embodiments, a square post 203 is fixedly provided on the hinge shaft, and a rotating hole 10101 corresponding to the hinge shaft is opened on the U-shaped plate 101. The hinge shaft passes through the rotating hole 10101, and the square post 203 is located inside the vertical tube. The driving assembly includes a swing arm 5. One end of the swing arm 5 is opened with a square hole 501 corresponding to the square post 203. The square post 203 is located inside the square hole 501. The end of the swing arm 5 away from the square hole 501 is connected to a slide rod 3. The slide rod 3 is located inside the vertical tube and is movably connected to the vertical tube along the length direction of the vertical tube.

[0058] Guide plates 301 are fixed at both ends of the slide rod 3. The width of the guide plate 301 matches the first side length of the inner side of the vertical tube, and the width of the slide rod 3 matches the second side length of the inner side of the vertical tube. The guide plate 301 plays a guiding role, making the movement of the slide rod 3 more stable.

[0059] A drive post 502 is fixedly mounted on one end of the swing arm 5 away from the square hole 501. A strip-shaped hole 302 corresponding to the drive post 502 is opened on the slide rod 3. The width of the strip-shaped hole 302 matches the diameter of the drive post 502. The strip-shaped hole 302 is arranged perpendicular to the moving direction of the slide rod 3, and the drive post 502 is located inside the strip-shaped hole 302. When the slide rod 3 moves, the drive post 502 moves within the strip-shaped hole 302, causing the slide rod 3 to drive the swing arm 5 to rotate, which in turn causes the louvered blades 2 to rotate.

[0060] A circular tube 303 is fixedly mounted on the guide plate 301. A strip-shaped through hole 10102 corresponding to the circular tube 303 is opened on the U-shaped plate 101. The width of the strip-shaped through hole 10102 matches the outer diameter of the circular tube 303. The circular tube 303 is located inside the strip-shaped through hole 10102. A sliding post 602 is provided inside the circular tube 303. A handle 6 is fixedly mounted at the end of the sliding post 602 away from the circular tube 303. The diameter of the handle 6 is larger than the diameter of the sliding post 602. A limiting groove 10103 corresponding to the strip-shaped through hole 10102 is provided on the outer side of the vertical tube. There are multiple limiting grooves 10103, which are evenly arranged along the length direction of the strip-shaped through hole 10102. A limiting plate 601 corresponding to the limiting groove 10103 is fixedly mounted on the handle 6. The limiting plate 601 is located inside the limiting groove 10103. The slide bar 3 has a groove corresponding to the round tube 303. The slide bar 3 and the bottom of the groove are connected by an elastic element 603 in a stretched state. The elastic element 603 can be, but is not limited to, existing stretched springs.

[0061] When adjusting the angle of the louver 2, hold the handle 6 and move the slide bar 602 outward. When the limiting plate 601 disengages from the limiting groove 10103, move the slide bar 3 upward or downward to rotate the louver 2, adjusting the gap between adjacent louver slats and thus adjusting ventilation and sound insulation. After adjustment, release the handle 6 and insert the limiting plate 601 into the limiting groove 10103 to prevent the slide bar 3 from moving further. The frame 1 is a structural component made of aluminum alloy, and the slide bar 3 is a structural component made of plastic.

[0062] All the louvers on one side of the louver slats are driven by a slide bar 3.

[0063] In some other embodiments, the drive assembly includes a swing arm 5, with a corresponding swing arm 5 for each hinge shaft 202 of each louver 2. One end of the swing arm 5 is fixedly connected to the hinge shaft 202, and the other end is connected to a connecting rod. The connecting rod is correspondingly provided with a drive electric cylinder, the output shaft of the electric cylinder is connected to the connecting rod, and the housing of the electric cylinder is fixedly connected to the vertical tube.

[0064] Work process:

[0065] When this plan is implemented, if Figure 13 As shown in the figure, the louver 2 in the left image is set horizontally, which provides the best ventilation performance but the worst sound insulation.

[0066] Figure 13 In the middle diagram, the louver 2 of the louver slats tilts downwards on the side furthest from the hinge axis 202. By adjusting the gap between the louver 2 of adjacent louver slats, the gap between adjacent louver slats forms a bend (as shown). Figure 13 The inverted V-shaped channel in the middle image ensures ventilation. Figure 13 At the same time (as indicated by the arrow at the top of the middle image), noise transmission requires multiple reflections (…). Figure 13 (The arrow at the bottom of the middle image) significantly improves the noise reduction effect. When the gap is reduced, noise transmission needs to go through more reflections, further improving the noise reduction effect.

[0067] Figure 13 In the lower middle image, the lower end of the slat 2 of the upper louver near the outer side is in contact with the slat 2 of the lower louver, at which point the gap is completely sealed.

[0068] In addition, the left louver 2 can be adjusted to be horizontal, and the right louver 2 can be adjusted to be tilted, depending on the environment.

[0069] The angle of the louver blades can be changed by adjusting the angle of louver blade 2, making it suitable for different environments and expanding the application range of louvers.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
