Description

Technical Field

[0001] This utility model relates to the field of venetian blind technology, specifically a venetian blind with noise reduction function. Background Technology

[0002] With the acceleration of urbanization, urban noise pollution has become increasingly serious. Traffic noise, industrial noise, and residential noise have caused many problems for people's lives and work. Venetian blinds are a type of window and a common interior decoration for new homes. They are almost always used in newly built buildings. Modern people advocate a healthy and comfortable life. Wood has an unparalleled natural beauty among all decoration materials. Unlike the soft texture of curtains, Venetian blinds are generally made of materials such as wood, glass, and aluminum alloy, so they can resist the erosion of sunlight, wind, rain, and dust, and are easy to clean.

[0003] Traditional venetian blinds mainly focus on adjusting light and ventilation, but are not very effective in noise reduction. Most existing venetian blinds have a single-layer structure and are made of a single material, which cannot effectively block external noise from entering the room and have poor noise filtering effect. In addition, most venetian blinds use electric opening and closing, which is inconvenient to adjust and generates a lot of noise. Therefore, we propose a venetian blind with noise reduction function. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a venetian blind with noise reduction function. It solves the problem that traditional venetian blinds mainly focus on adjusting light and ventilation, and are not very effective in noise reduction. Existing venetian blinds are mostly single-layer structures with a single material, which cannot effectively block external noise from entering the room and have poor noise filtering effect. In addition, most venetian blinds use electric opening and closing methods, which are inconvenient to adjust and generate a lot of noise.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a louver with noise reduction function, comprising a window frame, the window frame including an upper frame, a lower frame, and two side frames, which together form a rectangular frame structure. The window frame is provided with a blade assembly inside, and a driving device is provided at both ends of the blade assembly on the outside of the window frame. Multiple sets of equally spaced mounting holes are provided on both the left and right sides of the window frame. Mounting grooves are provided on the opposite side surfaces of the upper and lower frames of the window frame, and elastic sealing strips are fixedly installed inside the two sets of mounting grooves.

[0006] Furthermore, the driving device includes two sets of sealing frames fixedly installed on the outer surfaces of the left and right sides of the window frame. The two sets of sealing frames are rotatably connected to a rotating shaft inside and through multiple sets of mounting holes. One end of each of the multiple sets of rotating shafts is fixedly installed inside the window frame with a blade clamp.

[0007] Furthermore, a sliding positioning plate is slidably connected to the inner front end of the sealing frame on the right side. Multiple sets of rivets distributed at equal intervals are fixedly installed inside the sliding positioning plate, and the multiple sets of rivets are slidably connected to the inner front wall of the sealing frame on the right side.

[0008] Furthermore, straight groove plates are fixedly installed between the multiple sets of rivets and the multiple sets of rotating shafts.

[0009] Furthermore, a locking sleeve is fitted onto the circumferential surface of the rotating shaft, and the surface of the locking sleeve has multiple sets of sleeve holes that are adapted to the rotating shaft.

[0010] Furthermore, the blade assembly consists of multiple blades, and each blade is a composite structure consisting of a first blade and a second blade, with the first blade and the second blade being fitted together.

[0011] Furthermore, a cavity is formed between the first blade and the second blade, and sound-absorbing cotton is fixedly installed inside the cavity. Both ends of the first blade and the second blade are fixed to the blade clamping block.

[0012] This utility model provides a venetian blind with noise reduction function, which has the following beneficial effects:

[0013] 1. By setting up blade assemblies, elastic sealing strips are installed in the mounting grooves of the upper and lower edges of the window frame. After closing with the blade assembly, they cooperate to form the first seal. The sealing frame of the drive device covers the side of the window frame, sealing the gap between the blade assembly and the window frame, reducing the transmission of sound through the gap. The multiple sealing structures work together to greatly improve the overall sealing performance of the louver. At the same time, the sound-absorbing cotton installed between the first and second blades reduces the transmission of external noise from the structural level, playing a role in noise reduction and creating a quieter environment.

[0014] 2. By setting up a drive device, the rotating shaft passes through the mounting hole and connects to the blade assembly via the blade clamping block. The sliding positioning plate, rivets, and straight groove plate work together to precisely control the rotation of the blades. This adaptive structure allows for stable adjustment of the blade angle, enabling the opening and closing of the blades. At the same time, the locking sleeve is installed on any two sets of rotating shafts to prevent the rotating shafts from rotating on their own and to avoid additional noise caused by loosening or shaking. The blade angle can be flexibly adjusted to switch between ventilation and airtight noise reduction as needed, ensuring noise reduction effect and usage requirements in different scenarios.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a louver with noise reduction function, including a window frame 1, which includes an upper frame, a lower frame, and two side frames, forming a rectangular frame structure. The window frame 1 is provided with a blade assembly 2 inside, and a drive device 4 is provided at both ends of the blade assembly 2 on the outside of the window frame 1. Multiple sets of equally spaced mounting holes 5 are opened on both the left and right sides of the window frame 1. Mounting grooves 6 are opened on the opposite side surfaces of the upper and lower frames of the window frame 1. Elastic sealing strips 7 are fixedly installed inside the two sets of mounting grooves 6. The window frame 1, as the basic support structure of the louver, is formed by the upper frame, lower frame, and two side frames to provide a mounting carrier for the blade assembly 2, drive device 4, and other components, ensuring the overall structural stability of the louver. Its regular frame shape is also conducive to adapting to the installation environment.

[0024] The drive device 4 includes two sets of sealing frame 401 fixedly installed on the outer surfaces of the left and right sides of the window frame 1. The two sets of sealing frame 401 are rotatably connected to the inside of the two sets of sealing frame 401 and through multiple sets of mounting holes 5. One end of the multiple sets of rotating shafts 402 and located inside the window frame 1 is fixedly installed with a blade clamp 406. The blade assembly 2 is installed inside the window frame 1, and the two ends are rotated and adjusted by the drive device 4. The drive device 4 is arranged on the outside of the window frame 1. This layout facilitates the operation and control of the blade angle and can also provide a certain degree of protection for the drive components by utilizing the structure of the window frame 1. At the same time, the mounting holes 5 provide a position for the connection between the drive device 4 and the window frame 1. The elastic sealing strip 7 in the mounting groove 6 enhances the seal when the blade is closed, reducing noise and airflow penetration.

[0025] A sliding positioning plate 405 is slidably connected to the front end of the right sealing frame 401. Multiple sets of rivets 404 with equal spacing are fixedly installed inside the sliding positioning plate 405. The multiple sets of rivets 404 are slidably connected to the front inner wall of the right sealing frame 401. Straight groove pieces 403 are fixedly installed between the multiple sets of rivets 404 and the multiple sets of rotating shafts 402.

[0026] A locking sleeve 3 is fitted onto the circumferential surface of the rotating shaft 402, and the surface of the locking sleeve 3 has multiple sets of sleeve holes that are adapted to the rotating shaft 402.

[0027] The blade assembly 2 consists of multiple blades, and each blade is a composite structure composed of a first blade 21 and a second blade 22. The first blade 21 and the second blade 22 are fitted together, forming a cavity between them. Sound-absorbing cotton 23 is fixedly installed in the cavity. Both ends of the first blade 21 and the second blade 22 are fixed to the blade clamp 406. The single blade of the blade assembly 2 adopts a composite structure of the first blade 21 and the second blade 22 fitted together. The cavity formed provides a space for the sound-absorbing cotton 23. The sound-absorbing cotton 23 can absorb and attenuate the sound passing through the blade, improving the noise reduction capability of the louver. Both ends are fixed to the blade clamp 406 to ensure a reliable connection between the blade and the drive device 4, making the blade rotation adjustment more synchronous and smooth.

[0028] The detailed description of known functions and components is omitted in this disclosure. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of commercially available instruments.

[0029] In summary, the operating steps for this type of venetian blind with noise reduction function are as follows;

[0030] When the noise-reducing louver is in operation, the window frame 1 serves as the basic frame. The elastic sealing strip 7 in the mounting groove 6 closes with the blade assembly 2 to form a preliminary seal. The blade assembly 2, with its composite structure of the first blade 21 and the second blade 22 sleeved together and the built-in sound-absorbing cotton 23, absorbs and attenuates the incoming sound. In the drive device 4, the sealing frame 401 covers the side of the window frame 1 to further seal the gaps. The rotating shaft 402 passes through the mounting hole 5 and connects to the blade assembly 2 via the blade clamp 406. The sliding positioning plate 405, rivets 404, and straight groove plate 403 cooperate to precisely control the rotation angle of the blades. The locking sleeve 3 is sleeved on any two sets of rotating shafts 402 to lock the position of the rotating shafts 402 and prevent them from rotating or shaking and generating noise. Through the reinforcement of the sealing structure, the sound absorption of the blades, and the precise and stable control of the drive device 4, noise reduction and flexible opening and closing functions are achieved to meet the ventilation or sealing noise reduction needs in different scenarios. At this point, the entire process is complete.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
