Technical Field
[0001] This utility model relates to the field of louver technology, specifically a bridge-type sound-absorbing louver. Background Technology
[0002] Bridge-type noise-absorbing louvers are a special type of noise reduction device, primarily used to control and reduce noise propagation. They combine the features of noise-absorbing louvers and silencers, achieving highly efficient noise control through specific design and material selection.
[0003] Conventional bridge-type sound-absorbing louvers have relatively thin louver structures, which limits their structural strength and sound-absorbing capabilities. They rely on sound-absorbing cotton and other structures on the back for sound absorption and noise reduction, making it difficult to maximize their sound-absorbing effect.
[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a bridge-type sound-absorbing louver. Utility Model Content
[0005] The purpose of this invention is to provide a bridge-type sound-absorbing louver to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a bridge-type sound-absorbing louver, comprising a main window frame and louvers, wherein the louvers are vertically and equidistantly arranged inside the main window frame, and a secondary window frame is connected to one side of the main window frame, and a sound-absorbing component is installed on the side of the secondary window frame away from the main window frame, and a filter component is connected to the side of the sound-absorbing component away from the secondary window frame. The louvers include bridge-type louvers, connecting posts, and sound-absorbing panels, wherein connecting posts are symmetrically installed on the bottom of the bridge-type louvers, and sound-absorbing panels are provided on both the front and rear sides of the connecting posts.
[0007] Furthermore, the sound-absorbing panel is attached to the bottom front and rear sides of the bridge-shaped louver, and both the bridge-shaped louver and the sound-absorbing panel are made of sound-absorbing material.
[0008] Furthermore, the sound-absorbing component includes a first frame, a sound-absorbing grille, sound-absorbing cotton, and docking piles. The sound-absorbing grille is provided in the middle of the interior of the first frame, and sound-absorbing cotton is installed inside the sound-absorbing grille. Furthermore, docking piles are installed on both the upper and lower sides of the sound-absorbing grille.
[0009] Furthermore, the inner side of the first frame is provided with insertion holes that match the docking pile structure, and the sound-absorbing grille is connected to the first frame by a detachable structure.
[0010] Furthermore, the filter assembly includes a second frame, a filter grid, and connecting posts. The filter grid is movably installed in the middle of the interior of the second frame, and connecting posts are installed on both the upper and lower sides of the filter grid. In addition, the inner sides of the second frame are provided with insertion holes that match the structure of the connecting posts.
[0011] Furthermore, limiting rivets are inserted between the main window frame and the secondary window frame. Fixed pins are vertically inserted on the upper and lower sides of the sound-absorbing component and the filter component. Connecting screws are horizontally threaded through the four diagonal corners of the main window frame, the secondary window frame, the sound-absorbing component and the filter component. Once the limiting rivets are horizontally inserted into the connecting pile, they are securely fixed.
[0012] Furthermore, the fixing pins are connected to the first frame, the docking pile, the second frame, and the connecting pile by a movable insertion structure, and the first frame and the second frame have the same structure.
[0013] Furthermore, the middle section surface of the connecting screw is provided with a threaded structure, and one end of the connecting screw is provided with a screw structure that is slightly smaller than the diameter of the middle section of the connecting screw. Moreover, the other end of the connecting screw is provided with a threaded hole structure that matches the screw structure, so as to realize the structural function of connecting the connecting screws end to end for splicing.
[0014] This utility model provides a bridge-type sound-absorbing louver, which has the following beneficial effects:
[0015] 1. This utility model features a plurality of louvers arranged at equal intervals from top to bottom inside the main window frame. Sound-absorbing panels are attached to the front and back surfaces of the bottom of the bridge-shaped louvers, and both the louvers and the sound-absorbing panels are made of the same sound-absorbing material. The main window frame is connected to the bridge-shaped louvers via connecting posts at both ends of the bottom, along with limiting rivets. These rivets allow for axial rotation adjustment in the horizontal direction. This structure maximizes the sound absorption of the entire louver by utilizing the louvers and the sound-absorbing components. Furthermore, the rotational nature of the structure allows for adjustment of the sound absorption effect to meet different usage needs. This design ensures both the flexibility and practicality of the device structure.

The sound-absorbing panels 203 are attached to the front and rear sides of the bottom of the bridge-type louvers 201, and both the bridge-type louvers 201 and the sound-absorbing panels 203 are made of sound-absorbing material. The sound-absorbing component 4 includes a first frame 401, a sound-absorbing grille 402, sound-absorbing cotton 403, and connecting posts 404. The first frame 401 has a sound-absorbing grille 402 in the middle, and the sound-absorbing cotton 403 is installed inside the sound-absorbing grille 402. The upper and lower sides of the sound-absorbing grille 402 are equipped with docking posts 404. The upper and lower sides of the inner side of the first frame 401 are provided with insertion holes that match the structure of the docking posts 404. The sound-absorbing grille 402 and the first frame 401 are connected to each other by a detachable structure.

The bridge-shaped louver 201 and the sound-absorbing panels 203 are made of the same sound-absorbing material. In addition, the main window frame 1 is connected to the main window frame 1 by the connecting posts 202 at both ends of the bottom of the bridge-shaped louver 201 and the use of limiting rivets 6. The axial rotation adjustment can be performed in the horizontal direction with the limiting rivets 6 as the center.
[0026] like Figures 1 to 6As shown, the filter assembly 5 includes a second frame 501, a filter grille 502, and a connecting post 503.
