Description

Technical Field

[0001] This invention relates to the technical field of louver blade closing devices, specifically a bamboo and wood louver blade adsorption mechanism. Background Technology

[0002] Venetian blinds are a type of window that originated in China. In ancient Chinese architecture, there were vertical lattice windows, used from the Warring States period to the Han Dynasty. These windows with vertical lattice bars were called vertical lattice windows, while those with horizontal lattice bars were called horizontal lattice windows. The horizontal lattice window is a primitive form of venetian blinds, or you could say it represents the original state of venetian blinds.

[0003] Venetian blinds are a common piece of furniture in modern home decoration, serving both ventilation and privacy. They come in various styles based on the type of slats, with bamboo and wood slat blinds being particularly popular due to their natural wood grain. However, bamboo and wood slats are typically made of hard bamboo, which can trap dust in the wind, especially at night when it's windy and rainy. Homeowners may not be able to close the blinds immediately, and even when closed, the hardness of the slats means they don't fit together perfectly, leaving gaps. Furthermore, the slats absorb water and have a strong backflow effect, allowing rainwater to enter the home through these gaps or against the airflow, reducing comfort and limiting the applicability of venetian blinds. Summary of the Invention

[0004] The purpose of this invention is to provide a bamboo and wood louver blade adsorption mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bamboo and wood louver blade adsorption mechanism, comprising an outer frame and a plurality of blades, wherein the blades are made of bamboo and wood material, and the plurality of blades are arranged equidistantly from top to bottom within the outer frame;

[0006] Also includes:

[0007] Two fixing boxes are disposed opposite each other at opposite ends of a plurality of blades. The blades are connected to the two fixing boxes by a limiting component. The fixing boxes are connected to the outer frame by an adjusting component.

[0008] A magnetic strip is fixedly installed on one side of the blade, and an airbag is fixedly installed on the other side of the blade. A magnetic thin plate is fixedly installed on the inner wall of the airbag, and a positioning component is installed in both the blade and the corresponding airbag.

[0009] Preferably, the adjusting component includes a round rod, and a T-shaped groove is provided on the inner wall of the outer frame at the position corresponding to the middle of the fixed box. One end of the round rod is fixedly connected to the middle position of one side of the fixed box, and the other end of the round rod is inserted into the corresponding groove and a slider is rotatably sleeved through a bearing. The slider is slidably connected to the inner wall of the corresponding groove. A first spring is provided between the slider and the inner top wall of the corresponding groove, and the two ends of the first spring are fixedly connected to the corresponding slider and the inner top wall of the corresponding groove, respectively.

[0010] By adopting the above technical solution, the cooperation between the slider, the slide groove and the first spring allows the connection point between the fixed box and the outer frame to be adjusted in height as needed, which facilitates the overall angle adjustment of several blades.

[0011] Preferably, the inner top wall and the inner bottom wall of the outer frame are both inclined surfaces with opposite orientations, both ends of the fixing box are curved surfaces, and two blocks are fixedly installed on the inner bottom wall and the inner top wall of the outer frame at positions corresponding to the two fixing boxes.

[0012] By adopting the above technical solution, the inclined surface of the outer frame and the arc surface of the fixed box constrain and guide the rotation of the fixed box, and the stop block limits the rotation angle of the fixed box, which facilitates the angle adjustment of the fixed box.

[0013] Preferably, the limiting component includes a round tube, which is fixedly inserted into the middle position of the corresponding blade, and the two ends of the round tube are respectively inserted into two fixing boxes. Two soft sleeves are fitted on the outer periphery of the round tube, the inner wall of the soft sleeve is interference-fitted with the corresponding round tube, and the outer wall of the soft sleeve is fixedly connected to the box wall of the corresponding fixing box.

[0014] By adopting the above technical solution, several blades are supported and limited by a circular tube, and the friction between the circular tube and the outer frame is increased by a soft sleeve, so that the blades can only rotate when subjected to a large thrust.

[0015] Preferably, a limiting hole is provided on the other side of the fixing box at the position corresponding to the circular tube, a hexagonal rod is slidably inserted in the limiting hole, a ball is rotatably inserted at one end of the hexagonal rod, and a first hemispherical groove is provided on the inner side wall of the outer frame at the position corresponding to the ball.

[0016] By adopting the above technical solution, the threaded shaft will not rotate with the round hole due to the contact between the hexagonal rod and the inner wall of the limiting hole.

[0017] Preferably, the other end of the hexagonal rod is fixedly equipped with a threaded shaft, and the end of the threaded shaft away from the corresponding hexagonal rod is inserted into the round tube and threadedly connected to the round tube.

[0018] By adopting the above technical solution, the hexagonal rod is driven to extend and retract within the limiting hole through the contact between the threaded shaft and the rotating round rod, without the need for an additional power source.

[0019] Preferably, a piston plate is installed inside the circular tube, and the piston plate is rotatably connected to the corresponding threaded shaft through a bearing. The interior of the circular tube is connected to the interior of the corresponding airbag through several connecting pipes. Both the interior of the airbag and the interior of the circular tube are filled with air.

[0020] By adopting the above technical solution, the piston plate and the connecting pipe cooperate with each other to control the gas content in the airbag during the movement of the threaded rod, without the need for an external power source.

[0021] Preferably, the positioning component includes a connecting rod, two rectangular grooves are formed opposite to each other at the bottom of the blade, two magnetic push blocks with trapezoidal cross-sections are slidably installed in the rectangular grooves, a second hemispherical groove is formed on the side wall of the outer frame at the position corresponding to the rectangular grooves, a magnetic rod is slidably inserted in the blade at the position corresponding to the rectangular grooves, one end of the connecting rod is fixedly connected to the corresponding magnetic plate, and the other end of the connecting rod is inserted into the corresponding rectangular groove and fixedly connected to the corresponding magnetic push block, the connecting rod is slidably connected to the corresponding blade, and a sealing ring is installed on the outer periphery of the connecting rod.

[0022] By adopting the above technical solution, the magnetic rod is constrained and limited by the attraction between the magnetic rod and the magnetic pusher, so that the magnetic pusher is always in contact with the magnetic rod, preventing the magnetic rod from falling out of the blades.

[0023] Preferably, one end of the magnetic rod is hemispherical and the other end is inclined. The other end of the magnetic rod is inserted into the corresponding rectangular groove and contacts the inclined surface of the corresponding magnetic push block.

[0024] By adopting the above technical solution, the inclined surface of the magnetic rod and the inclined surface of the magnetic pusher facilitate the pushing of the magnetic rod by the magnetic pusher. Furthermore, the hemispherical shape of the magnetic rod cooperates with the arc surface of the second hemispherical groove, so that when the arc surface of the second hemispherical groove comes into contact with the hemispherical end of the second hemispherical groove, the magnetic rod can be squeezed out of the second hemispherical groove.

[0025] Preferably, a second spring is provided between the magnetic push block and the inner bottom wall of the corresponding rectangular groove, and the two ends of the second spring are fixedly connected to the corresponding magnetic push block and the inner bottom wall of the corresponding rectangular groove, respectively.

[0026] By adopting the above technical solution, the magnetic push block is reset by the elastic assistance of the second spring during reset, which facilitates the reset operation of the two-wheeled magnetic push block.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: When it is windy and rainy at night, the blades of this improved louver will be pushed by the strong airflow, causing the blades to rotate. During the process of the blades rotating and closing, the overall tilt angle of several blades is adjusted by the cooperation of the adjusting component and the limiting component. When the blades are in a vertical position, the gaps between several blades are sealed by the cooperation of the limiting component, the magnetic strip, the magnetic plate and the airbag. During this process, the positioning component is driven to complete the enhanced constraint and limiting of the blades in the vertical position. At this time, several blades are combined to form an integral plate and are in an inclined state. When rainwater hits the blades, they slide down the inclined surface of the blades onto the inclined surface of the inner bottom side of the outer frame, and then slide down the inclined surface of the inner bottom side of the outer frame to the outside of the house. This improves the applicability of the louver. The specific details are as follows.

[0028] 1. Equipped with an airbag, magnetic strips, and magnetic sheet, this improved louver, made of high-hardness bamboo and wood, rotates when propelled by strong airflow during windy and rainy nights. As several blades rotate and close, the overall tilt angle of the blades and fixing box is adjusted through the cooperation of the adjusting and limiting components. When the blades are in a vertical position, the airbag, pushed by the limiting component, expands and stretches in a directional manner, adhering to the corresponding magnetic strips to seal the gaps between the blades. During this process, the positioning component further reinforces the vertical constraint of the blades, stabilizing the sealed gaps. The combined blades form a single, tilted panel. When rainwater hits the blades, it slides down the inclined surface of the outer frame onto the inner bottom slope and then out of the house. Because the blades block external airflow and rainwater from entering the house, the louver's applicability is enhanced. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8This invention provides a technical solution: a bamboo and wood venetian blind blade adsorption mechanism, comprising an outer frame 1 and several blades 2. The surface of the blades 2 is coated with a waterproof layer. The outer frame 1 is installed inside the window frame of the room. The blades 2 are made of bamboo and wood. Several blades 2 are arranged equidistantly from top to bottom inside the outer frame 1. Pull ropes are threaded through both the blades 2 and the outer frame 1, and the pull ropes control the rotation of the blades 2. It should be noted that due to the arcuate design of the corners of the blades 2, the outer frame 1 does not affect the rotation of the blades 2, and the pull ropes controlling the rotation of the blades 2 is a conventional venetian blind control mechanism. The structure also includes: two fixing boxes 6, which are vertically opposite each other at opposite ends of several blades 2. A pull rod is fixedly installed on the side of the two fixing boxes 6 closest to the interior, and a pull rope is fixedly connected to the blades 2. The pull rope is also interference-fitted with the outer frame 1. One end of each blade 2 is in contact with the fixing box 6, and the portion of the fixing box 6 closest to the inner wall of the outer frame 1 is in contact with the inner side wall of the outer frame 1. A magnetic strip 7 is fixedly installed on one side of each blade 2, and an airbag 9 is fixedly installed on the other side of each blade 2. A magnetic thin plate 8 is fixedly installed on the inner wall of the airbag 9. The fixing boxes 6 are connected to the outer frame 1 via an adjusting assembly 3. The adjusting component 3 includes a round rod 32. A T-shaped groove 31 is provided on the inner wall of the outer frame 1 at the position corresponding to the middle of the fixed box 6. One end of the round rod 32 is fixedly connected to the middle position of one side of the fixed box 6. The other end of the round rod 32 is inserted into the corresponding groove 31 and a slider 33 is mounted on it via a bearing. The slider 33 is slidably connected to the inner wall of the corresponding groove 31. A first spring 34 is provided between the slider 33 and the inner top wall of the corresponding groove 31, and the two ends of the first spring 34 are respectively... The inner top walls of the corresponding slider 33 and corresponding groove 31 are fixedly connected. The inner top wall and inner bottom wall of the outer frame 1 are both inclined surfaces. Both ends of the fixed box 6 are curved surfaces. Two stops 35 are fixedly installed on the inner bottom wall and inner top wall of the outer frame 1 at the positions corresponding to the two fixed boxes 6. When the fixed box 6 is in a vertical state, the fixed box 6 contacts the corresponding upper stop 35. When the fixed box 6 is in an inclined state, the fixed box 6 contacts the corresponding lower stop 35. The cooperation between the slider 33, the groove 31 and the first spring 34 allows the connection point between the fixed box 6 and the outer frame 1 to be adjusted in height as needed. Since the round rod 32 and the slider 33 are rotatably connected through the slider 33, the rotation of the fixed box 6 is not affected when the height of the round rod 32 is adjusted. The inclined surface of the outer frame 1 and the curved surface of the fixed box 6 constrain and guide the rotation of the fixed box 6, and the stop 35 limits the angle of rotation of the fixed box 6.

[0040] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the blade 2 is connected to two fixed boxes 6 via a limiting component 4. The limiting component 4 includes a round tube 41, which is fixedly inserted into the middle position of the corresponding blade 2, with both ends of the round tube 41 inserted into the two fixed boxes 6 respectively. Two soft sleeves 42 are fitted onto the outer periphery of the round tube 41, with the inner wall of the soft sleeve 42 interference fit with the corresponding round tube 41 and the outer wall of the soft sleeve 42 fixedly connected to the box wall of the corresponding fixed box 6. A limiting hole 43 is opened on the other side of the fixed box 6 at the position corresponding to the round tube 41, and a hexagonal rod 44 slides through the limiting hole 43. The hexagonal rod 44 can also be a quadrangular rod or other polygonal prism shape. A ball bearing 45 is rotatably inserted through one end of the hexagonal rod 44. A first hemispherical groove 46 is provided on the inner wall of 1 at the position corresponding to the ball 45. When the blade 2 is in an inclined state, part of the ball 45 is inserted into the first hemispherical groove 46. The other end of the hexagonal rod 44 is fixedly equipped with a threaded shaft 47, and the end of the threaded shaft 47 away from the corresponding hexagonal rod 44 is inserted into the round tube 41 and threadedly connected to the round tube 41. A piston plate 48 is installed in the round tube 41, and the piston plate 48 is rotatably connected to the corresponding threaded shaft 47 through a bearing. The inside of the round tube 41 is connected to the inside of the corresponding airbag 9 through several connecting pipes 49. The inside of the airbag 9 and the inside of the round tube 41 are both filled with air. The circular tube 41 supports and limits several blades 2, and the soft sleeve 42 increases the friction between the circular tube 41 and the outer frame 1. The contact between the hexagonal rod 44 and the inner wall of the limiting hole 43 prevents the threaded shaft 47 from rotating with the circular hole. The contact between the threaded shaft 47 and the rotating circular tube 41 drives the hexagonal rod 44 to extend and retract within the limiting hole 43. The cooperation between the piston plate 48 and the connecting tube 49 controls the gas content in the airbag 9 during the movement of the threaded rod.

[0041] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, a positioning component 5 is installed both inside the blade 2 and the corresponding airbag 9. The positioning component 5 includes a connecting rod 55. Two rectangular slots 51 are formed opposite each other at the bottom of the blade 2. Two magnetic push blocks 52 with trapezoidal cross-sections are slidably installed in the rectangular slots 51. A second hemispherical slot 53 is formed on the side wall of the outer frame 1 at the position corresponding to the rectangular slots 51. A magnetic rod 54 is slidably inserted through the blade 2 at the position corresponding to the rectangular slots 51. When the blade 2 is in a vertical state, the hemispherical end of the magnetic rod 54 is inserted into the corresponding second hemispherical slot 53. One end of the connecting rod 55 is fixedly connected to the corresponding magnetic plate 8, and the other end of the connecting rod 55 is inserted into the corresponding rectangular slot 51 and connected to the corresponding magnetic plate 8. The magnetic push block 52 is fixedly connected, the connecting rod 55 is slidably connected to the corresponding blade 2, and a sealing ring 56 is installed on the outer periphery of the connecting rod 55 to seal the gap between the connecting rod 55 and the corresponding blade 2. One end of the magnetic rod 54 is hemispherical and the other end is inclined. The other end of the magnetic rod 54 is inserted into the corresponding rectangular groove 51 and contacts the inclined surface of the corresponding magnetic push block 52. A second spring 57 is provided between the magnetic push block 52 and the inner bottom wall of the corresponding rectangular groove 51, and the two ends of the second spring 57 are fixedly connected to the inner bottom wall of the corresponding magnetic push block 52 and the corresponding rectangular groove 51, respectively. The magnetic rod 54 is constrained and limited by the attraction between the magnetic rod 54 and the magnetic push block 52, so that the magnetic push block 52 is always in contact with the magnetic rod 54. The inclined surface of the magnetic rod 54 and the inclined surface of the magnetic push block 52 facilitate the pushing of the magnetic rod 54 by the magnetic push block 52. The hemispherical shape of the magnetic rod 54 cooperates with the arc surface of the second hemispherical groove 53, so that when the arc surface of the second hemispherical groove 53 abuts against the hemispherical end of the second hemispherical groove 53, the magnetic rod 54 can be squeezed out of the second hemispherical groove 53. The elasticity of the second spring 57 during reset pushes the magnetic push block 52 to reset.

[0042] Working principle: When it is windy and rainy outside at night, the strong airflow drives the blade 2 to rotate as air flows into the room. When the blade 2 rotates, it will drive the round tube 41 to rotate at the same time. As the round tube 41 rotates, the round tube 41 comes into contact with the threaded shaft 47, causing the threaded shaft 47 to retract and move into the round tube 41, thereby pulling the ball 45 out of the first hemispherical groove 46 and releasing the limiting state of the fixed box 6. After the limiting state of the fixed box 6 is released, the first spring 34 pushes the slider 33 to move downward. Due to the contact and guiding constraint between the arc surface of the fixed box 6 and the inclined surface of the outer frame 1, the fixed box 6 rotates and stops rotating when it contacts the contact stop 35, thereby adjusting the overall tilt angle of several blades 2.

[0043] It should be noted that as the fixed box 6 rotates, the gap between the ball 45 and the opening of the first hemispherical groove 46 will also increase due to the movement of the ball 45. This allows the ball 45 to be pulled out of the hemispherical groove and still be able to make a certain tilt adjustment simultaneously.

[0044] As the threaded shaft 47 retracts and moves into the round tube 41, it drives the piston plate 48 to slide inward, thereby increasing the air pressure inside the round tube 41. Subsequently, the gas inside the round tube 41 flows into the airbag 9 through the connecting pipe 49, causing the retracted airbag 9 to unfold and drive the magnetic plate 8 to move in a specific direction. At the same time, due to the push of the second spring 57, the magnetic push block 52 will not slide in the rectangular groove 51 due to the pull of the connecting rod.

[0045] As blade 2 rotates, when blade 2 is in a vertical position, magnetic strip 7 and magnetic plate 8 attract each other, reaching their maximum value when blade 2 is in a vertical position. The attraction between magnetic strip 7 and magnetic plate 8, combined with the gas push in airbag 9, causes magnetic plate 8 to continue moving towards magnetic strip 7, thereby causing airbag 9 to expand and deform and fit with the corresponding magnetic strip 7, sealing the gap between blades 2. At the same time, the attraction between magnetic strip 7 and magnetic plate 8, combined with the gas pushing force on magnetic plate 8, counteracts the elastic force of second spring 57, causing magnetic push block 52 to slide towards magnetic plate 8, thereby pushing the hemispherical groove of magnetic rod 54 into the second hemispherical groove 53. Through the contact between magnetic rod 54 and second hemispherical groove 53, the friction between round rod 32 and several sets, and the attraction between magnetic plate 8 and magnetic strip 7, the vertical state of blade 2 is limited and constrained, so that several blades 2 form a whole plate.

[0046] It should be noted that a certain attraction is only generated when the magnetic strip 7 and the airbag 9 are close to a certain extent. At this time, the blade 2 is close to the vertical state. Therefore, even if the magnetic rod 54 tries to be pushed out from the blade 2, the magnetic rod 54 will not slide out from the blade 2 due to the obstruction of the inner side wall of the outer frame 1. As the blade 2 rotates, the magnetic rod 54 can only slide out from the blade 2 normally when it corresponds to the second hemispherical groove 53.

[0047] The above-mentioned blades 2 are combined to form an integral board, which is tilted. When rainwater hits the blades 2, it slides down the inclined surface of the blades 2 and falls onto the inclined surface of the inner bottom side of the outer frame 1, and then slides down the inclined surface of the inner bottom side of the outer frame 1 to the outside of the house.

[0048] When resetting the blinds, firstly, the pull rod pulls the two fixed boxes 6, causing several blades 2 to rotate and reset, and also causes the slider 33 to rise and reset, recompressing the first spring 34. Then, the two pull ropes pull the blades 2 to rotate and reset in the opposite direction. Due to the contact between the second hemispherical groove 53 and the hemispherical surface of the magnetic rod 54, the magnetic rod 54 is squeezed out of the second hemispherical groove 53. At the same time, the magnetic push block 52 is pushed and reset by the second spring 57 and the magnetic rod 54 pushing the magnetic block, and also causes the magnetic plate 8 to reset and move, increasing the distance between the magnetic plate 8 and the magnetic strip 7. At the same time, the contact between the ring and the threaded shaft 47 pushes the hexagonal rod 44 to slide and reset in the limiting groove, and makes the roller... The ball 45 is inserted into the first hemispherical groove 46. The position between the fixed box 6 and the outer frame 1 is fixed by the contact between the inner wall of the first hemispherical groove 46 and the corresponding ball 45, so that the fixed box 6 will not rotate due to the push of the first spring 34. As the threaded rod moves, the piston moves and resets in the round rod 32, which generates negative pressure in the round rod 32 and draws the gas in the airbag 9 into the round tube 41, causing the airbag 9 to contract and reset. After the position of the blade 2 is adjusted, the attraction between the magnetic strip 7 and the magnetic plate 8 disappears due to the large gap between them. The inclination angle of the blade 2 is temporarily fixed by the friction between the soft sleeve 42 and the round tube 41.
