Description

Technical Field

[0001] This utility model relates to the field of louver technology, and in particular to a bamboo and wood louver structure with reinforcing ribs to prevent bending. Background Technology

[0002] In practical applications such as home window shading and ventilation, and office light control, bamboo and wood venetian blinds are popular among consumers due to their natural beauty and warm texture. Venetian blinds are a commonly used light-blocking product with light-adjusting, sun-shading, heat-insulating, and thermal-insulating properties. They can be used inside or outside buildings. By adjusting the angle of the slats, the incoming light can be controlled, thus greatly improving the comfort of people's lives and work.

[0003] Existing technologies, such as utility model patent CN 209413815 U, disclose a Venetian blind and venetian blind, including two opposing first sides and two opposing second sides, wherein the length of the first sides is shorter than that of the second sides; a side fastener is located on the first side of the main body, the side fastener is integrally formed with the main body, and the side fastener is used to fix the main body and the guide rail of the Venetian blind located on the first side of the main body. Through the above method, this application can improve the wind resistance performance of the Venetian blind.

[0004] When the above-mentioned technical solution is used, the louvers are prone to bending and deformation due to uneven stress when subjected to strong winds. On windows of some high-rise buildings, where the external wind force is strong, the louvers are more likely to bend and deform. This not only affects the normal use of the louvers and reduces their service life, but may also damage their aesthetics and cause a lot of inconvenience to users.

[0005] To address the aforementioned problems, this utility model provides a bamboo and wood louver structure with reinforcing ribs to prevent bending. Utility Model Content

[0006] The purpose of this invention is to solve the problems of easy bending and deformation of louvers and poor structural stability in the existing technology, and to propose a bending-resistant bamboo and wood louver structure with reinforcing ribs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a bamboo and wood louver structure with reinforcing ribs for preventing bending, comprising a connecting frame, a louver mechanism and a rotating connecting mechanism, characterized in that: the louver mechanism and the rotating connecting mechanism are fixedly connected to the interior of the connecting frame, and the louver mechanism includes connecting through holes opened on both sides of the connecting frame.

[0008] The louver mechanism includes an internal reinforcing rib and an outer surface reinforcing rib, which are fixedly connected to the rotating louver.

[0009] A rotating positioning post is rotatably connected inside the connecting through hole. A rotating ring is fixedly connected to one side of the rotating louver. The rotating ring is rotatably connected to the outer surface of the rotating positioning post. The outer surface reinforcing rib is fixedly connected to the other side of the rotating louver. The inner reinforcing rib is evenly fixedly connected to the inside of the rotating louver at equal intervals. The rotating louver and the rotating positioning post are evenly arranged at ten equal intervals inside the connecting frame.

[0010] Furthermore, bearings are rotatably connected to both ends of the rotating positioning column, the outer surface of the bearings is fixedly connected to the inside of the connecting through hole, and the rotating positioning column is rotatably connected to the inside of the connecting frame through the bearings.

[0011] Furthermore, the rotating connection mechanism includes a rotating component fixedly connected inside the connecting frame, and a connecting rope is fixedly connected to the outer surface of the rotating component. The outer surface of the connecting rope is fixedly connected to both sides of the rotating louvers that are arranged at ten equal intervals.

[0012] Furthermore, a positioning ring is fixedly connected at the connection between the connecting rope and the rotating louver, and the positioning ring and the connecting rope are symmetrically arranged on both sides of the rotating louver.

[0013] Furthermore, there are two sets of rotating components, which are symmetrically arranged inside the connecting frame. Each rotating component includes a micro servo motor fixedly connected to the inner wall of the connecting frame. The output end of the micro servo motor is fixedly connected to a main rotating shaft. A rotating belt is rotatably connected to the outer surface of the main rotating shaft. A driven rotating shaft is rotatably connected inside the rotating belt. The driven rotating shaft is rotatably connected to the inner bottom wall of the connecting frame.

[0014] Furthermore, the main rotating shaft and the driven rotating shaft are symmetrically arranged inside the rotating belt. The driven rotating shaft rotates synchronously with the main rotating shaft through the rotating belt. A rope rotator is fixedly connected to the outer surface of the main rotating shaft and the driven rotating shaft, and the two ends of the connecting rope are fixedly connected to the outer surface of the rope rotator.

[0015] Furthermore, a connecting plate is fixedly connected to the outer surface of the connecting frame, and connecting bolts are threaded to both sides of the connecting plate. The connecting plate and the connecting bolts are symmetrically arranged on both sides of the connecting frame.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, the strength of the rotating louver is enhanced from both the inside and outside by setting internal reinforcing ribs and external reinforcing ribs. The equidistant and uniform arrangement of the internal reinforcing ribs provides all-round support from the inside, while the external reinforcing ribs are evenly distributed along the outer surface to provide additional protection. The two work together to effectively improve the bending resistance of the bamboo and wood louver. In actual use, even when encountering strong winds, the rotating louver can maintain a good shape and is not easy to bend or deform, which greatly extends the service life of the louver.

[0018] 2. In this utility model, by setting up a rotating connection mechanism, a micro servo motor drives the main rotating shaft to rotate, and then a rotating belt drives the secondary rotating shaft to rotate synchronously, realizing the release and retraction of the connecting rope, thereby precisely controlling the opening and closing angle of the rotating louvers. This automated control method makes operation more convenient and can ensure that the opening and closing angle of each rotating louver is consistent, saving manpower and improving the accuracy and efficiency of adjustment. The positioning ring ensures the force balance when the rotating louvers rotate, greatly improving the user experience of the blinds. Attached Figure Description

[0027] Please see Figure 1-6 This utility model provides a technical solution: a bamboo and wood louver structure with reinforcing ribs to prevent bending, including a connecting frame 1, a louver mechanism 2 and a rotating connecting mechanism 3. The louver mechanism 2 and the rotating connecting mechanism 3 are fixedly connected to the inside of the connecting frame 1. The louver mechanism 2 includes connecting through holes 21 opened on both sides of the connecting frame 1.

[0028] The specific configuration and function of its louver mechanism 2 and rotating connection mechanism 3 will be explained below.

[0029] In this embodiment, the louver mechanism 2 includes an internal reinforcing rib 22 and an outer surface reinforcing rib 23, which are fixedly connected to the rotating louver 24.

[0030] A rotating positioning post 25 is rotatably connected inside the connecting through hole 21. A rotating ring 26 is fixedly connected to one side of the rotating louver 24. The rotating ring 26 is rotatably connected to the outer surface of the rotating positioning post 25. The outer surface reinforcing rib 23 is fixedly connected to the other side of the rotating louver 24. The inner reinforcing rib 22 is evenly fixedly connected to the inside of the rotating louver 24 at equal intervals. The rotating louver 24 and the rotating positioning post 25 are evenly distributed at ten equal intervals inside the connecting frame 1.

[0031] The effects achieved by the above components are as follows: the internal reinforcing ribs 22 form a stable support system for the rotating louvers 24 from the inside, evenly distributing the pressure applied from the outside and effectively improving its ability to resist bending deformation; the external reinforcing ribs 23 are evenly distributed along the length of the rotating louvers 24, and can directly bear and disperse the force when resisting external impacts such as wind, further enhancing its bending resistance; the cooperation between the rotating positioning post 25 and the rotating ring 26 provides a stable rotation fulcrum for the rotating louvers 24; the evenly distributed layout of ten equal parts ensures that each rotating louver 24 is subjected to uniform force during the opening and closing of the louvers, avoiding damage to local areas due to excessive force, and making the opening and closing operation of the louvers smoother and more stable.

[0032] Specifically, bearings 27 are rotatably connected to both ends of the rotating positioning column 25. The outer surface of the bearing 27 is fixedly connected to the inside of the connecting through hole 21, and the rotating positioning column 25 is rotatably connected to the inside of the connecting frame 1 through the bearings 27.

[0033] The effects achieved by the above components are as follows: the bearing 27 greatly reduces the friction of the rotating positioning column 25 when it rotates, making its rotation more flexible and smooth. The bearing 27 and the connecting through hole 21 are fixed by interference fit, ensuring that the rotating positioning column 25 will not wobble or shift during rotation, thus ensuring the stability and accuracy of the rotation of the rotating louver 24, reducing noise caused by component shaking, and improving the user experience.

[0034] Specifically, the rotating connection mechanism 3 includes a rotating component 31 fixedly connected inside the connecting frame 1. A connecting rope 32 is fixedly connected to the outer surface of the rotating component 31. The outer surface of the connecting rope 32 is fixedly connected to both sides of the rotating louvers 24, which are arranged at ten equal intervals.

[0035] The effect achieved by the above components is as follows: the rotating assembly 31 transmits power to the rotating louver 24 through the connecting rope 32, thereby driving the louver. The connecting rope 32 can withstand a large tension and is not easy to break, reliably connecting the rotating assembly 31 and the rotating louver 24, ensuring stable power transmission, and enabling the rotating louver 24 to open and close as expected.

[0036] Specifically, a positioning ring 33 is fixedly connected at the connection between the connecting rope 32 and the rotating louver 24, and the positioning ring 33 and the connecting rope 32 are symmetrically arranged on both sides of the rotating louver 24.

[0037] The effects achieved by the above components are as follows: the positioning ring 33, with its elasticity and anti-slip properties, firmly fixes the connection between the connecting rope 32 and the rotating louver 24, preventing the rope from slipping or falling off during the pulling process. The symmetrical structure on both sides ensures that the rotating louver 24 is subjected to balanced forces when rotating, avoiding tilting or jamming, and making the rotation of the louver more stable and smooth.

[0038] Specifically, there are two sets of rotating components 31. The rotating components 31 are symmetrically arranged inside the connecting frame 1. The rotating components 31 include a micro servo motor 311 fixedly connected to the inner wall of the connecting frame 1. The output end of the micro servo motor 311 is fixedly connected to a main rotating shaft 312. A rotating belt 313 is rotatably connected to the outer surface of the main rotating shaft 312. A secondary rotating shaft 314 is rotatably connected inside the rotating belt 313. The secondary rotating shaft 314 is rotatably connected to the inner bottom wall of the connecting frame 1.

[0039] The effects achieved by the above components are as follows: the symmetrically arranged rotating components 31 ensure that the tension of the connecting rope 32 on the rotating louver 24 is evenly distributed, so that the force on each part of the louver is consistent when the louver is opened and closed, avoiding damage to the louver due to uneven force; the micro servo motor 311 has high-precision speed control and good response performance, and can accurately adjust the rotation speed and angle; the transmission system composed of the main rotating shaft 312, the rotating belt 313 and the driven rotating shaft 314 stably and reliably transmits the motor power, ensuring the stability and accuracy of the power transmission process.

[0040] Specifically, the main rotating shaft 312 and the driven rotating shaft 314 are symmetrically arranged inside the rotating belt 313. The driven rotating shaft 314 rotates synchronously with the main rotating shaft 312 through the rotating belt 313. The outer surfaces of the main rotating shaft 312 and the driven rotating shaft 314 are fixedly connected to the rope rotator 315, and the two ends of the connecting rope 32 are fixedly connected to the outer surface of the rope rotator 315.

[0041] The effects achieved by the above components are as follows: the main rotating shaft 312 and the driven rotating shaft 314 rotate synchronously through the rotating belt 313, ensuring that the winding and unwinding speed of the connecting rope 32 is consistent, thereby enabling the rotating louver 24 to open and close synchronously and smoothly. The rope rotator 315, with its high strength and wear resistance, can withstand the tension of the connecting rope 32 and is connected to the rope by winding, which facilitates the winding and unwinding operation of the rope and achieves precise control of the opening and closing angle of the rotating louver 24.

[0042] Specifically, a connecting plate 4 is fixedly connected to the outer surface of the connecting frame 1, and connecting bolts 5 are threadedly connected to both sides of the connecting plate 4. The connecting plate 4 and the connecting bolts 5 are symmetrically arranged on both sides of the connecting frame 1.

[0043] The effects achieved by the above components are as follows: the connecting plate 4 is firmly fixed to the connecting frame 1 by welding, providing an installation base for the entire louver structure; the connecting bolts 5 symmetrically arranged on both sides facilitate the stable installation of the connecting frame 1 in fixed positions such as windows; the installation process is simple and quick, and can ensure that the connecting frame 1 has good stability after installation, so that the louver can be reliably fixed in the place of use.

[0044] Working principle: When the blinds need to be adjusted, the micro servo motor 311 is started. The output of the motor drives the main rotating shaft 312 to rotate. The main rotating shaft 312 drives the rotating shaft 314 to rotate synchronously through the rotating belt 313. The rope rotator 315 on the outer surface of the main rotating shaft 312 rotates accordingly, realizing the winding and unwinding of the connecting rope 32.

[0045] The connecting rope 32 pulls the rotating louver 24, causing it to rotate around the rotating positioning post 25 via the rotating ring 26, thereby adjusting the opening and closing angle of the louver. During this process, the internal reinforcing rib 22 and the outer surface reinforcing rib 23 work together to enhance the bending resistance of the rotating louver 24 and resist the influence of external wind and other factors.

[0046] The positioning ring 33 ensures that the connecting rope 32 and the rotating louver 24 are firmly connected and the force is balanced; the bearing 27 ensures that the rotating positioning column 25 rotates smoothly and steadily. All components cooperate with each other to achieve precise, stable and reliable opening and closing operation of the louver.
