Description

Technical Field

[0001] This utility model relates to the field of louver design, and in particular to a double-layered large-size louver with waterproof performance. Background Technology

[0002] Venetian blinds are a common window shading and privacy protection device, consisting of multiple horizontally or vertically arranged slats. These slats can be adjusted to control the amount of light and ventilation entering a room. Venetian blinds are widely used in homes, offices, commercial buildings, and other places.

[0003] Traditional blinds typically require manual adjustment of the slat angle to control the amount of light and ventilation entering the room. However, this manual adjustment method is not only inconvenient to operate, but also more difficult when the blinds are in high or hard-to-reach locations. In addition, on rainy days, rainwater can easily seep into the room through the gaps between the slats, causing indoor dampness and even damaging furniture and floors. Long-term moisture erosion will also shorten the lifespan of the blinds.

[0004] Therefore, there is an urgent need to design a double-layered, large-size louver with waterproof properties. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a double-layer large-size louver with waterproof performance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: A double-layered large-size louver with waterproof performance, such as... Figures 1-8As shown, the device includes a support frame 1, inner louvers 2, connecting rod 4, crank 5, insert plate 6, slider 7, bearing seat 8, lead screw 9, mounting base 10, motor 11, outer louvers 13, gear 14, rack 15, collection frame 17, spring 18, and guide rod 19. The support frame 1 provides support and mounting foundation for the entire device. The support frame 1 can be fixed to a wall or window frame with bolts. Several equidistant drain holes 201 are opened on the bottom front edge of the support frame 1. The drain holes 201 are formed by punching or drilling and are used to drain water accumulated inside the support frame 1. The outer end face of the bottom front edge of the support frame 1 is inclined. An inner louver 2 is rotatably installed in the rear inner part of the support frame 1. The inner louver 2 is used to control the amount of light entering the room and the ventilation, so as to achieve the adjustment of indoor light and ventilation. Several connecting rods 4 are equidistantly hinged to one side of the rear of the support frame 1. When the connecting rods 4 rotate, the slats of the inner louver 2 can open or close synchronously. Each connecting rod 4 is connected to the corresponding end of the louver of the inner louver 2. A crank 5 is hinged together among the connecting rods 4. The crank 5 drives the connecting rods 4 to move up and down, thereby controlling the opening and closing of the inner louver 2. A plate 6 is slidably installed on the lower part of the rear of the support frame 1 on the same side as the connecting rods 4. The plate 6 is fixed to the lower part of the crank 5 by screws. A slider 7 is installed on the plate 6. The slider 7 drives the crank 5 to move up and down, thereby controlling the opening and closing of the inner louver 2. A bearing seat 8 is fixed to the lower rear of the support frame 1 by bolts. A lead screw 9 is rotatably installed on the bearing seat 8. The slider 7 is rotatably connected to the lead screw 9. The lead screw 9 drives the slider 7 to move along its own direction. The inner louver 2 is controlled by moving the frame 1. A mounting base 10 is located at the bottom rear of the frame 1, near the bottom edge. A motor 11 is bolted to the bottom of the mounting base 10. The output shaft of the motor 11 passes through the interior of the mounting base 10 and is connected to a lead screw 9 via a coupling. The motor 11 provides driving force, driving the lead screw 9 to rotate. An outer louver 13 is rotatably mounted on the front of the frame 1. The outer louver 13 controls the amount of light entering the room and ventilation, and automatically closes to prevent rain. Several gears 14 are equidistantly and rotatably mounted on one side of the front of the frame 1. Each gear 14 is connected to the louvers of the outer louver 13 via keyways, allowing the louvers of the outer louver 13 to open or close synchronously. The front of the frame 1 slides on the same side as the gears 14. A rack 15 is provided, and several gears 14 mesh with adjacent racks 15. The racks 15 drive the gears 14 to rotate, thereby controlling the opening and closing of the outer louvers 13. The upper part of the rack 15 extends upward, forming an extension section. A collection frame 17 is provided on one side of this extension section to collect rainwater. Under the action of gravity, the extension frame descends, triggering the closing of the outer louvers 13. Several equally spaced drainage holes 20 are provided on one side of the lower part of the collection frame 17. The drainage holes 20 are formed by stamping or drilling and are used to drain the rainwater from the collection frame 17. The collection frame 17 is located directly above the top of the support frame 1, and several equally spaced springs 18 are provided between the bottom of the collection frame 17 and the top of the support frame 1. The springs 18 provide support for the collection frame 17, keeping the outer louvers 13 in the open state when there is no rainwater.To facilitate ventilation and lighting, a guide rod 19 is slidably mounted on the other side of the front of the support frame 1. The end of the guide rod 19 extends upward and connects to the collection frame 17. The guide rod 19 provides guidance for the collection frame 17, ensuring its smooth descent.

[0025] like Figure 5 and Figure 7 As shown, it also includes limiting blocks 12. The two sides of the front part of the support frame 1 are symmetrically provided with inclined limiting blocks 12. The bottom end of each limiting block 12 abuts against the blade surface of the corresponding outer louver 13. The limiting blocks 12 are used to limit the opening and closing size of the blades of the outer louver 13 to ensure that the blades do not open excessively when opened.

[0026] like Figure 1 , Figure 2 , Figure 7 and Figure 7 As shown, it also includes a cover plate 3 and a cover plate 16. A cover plate 3 for covering the components is provided on one side of the rear part of the support frame 1. The cover plate 3 covers the outside of the motor 11 and the connecting rods 4 and other components. A cover plate 16 for covering the components is provided on one side of the front part of the support frame 1. The cover plate 16 covers the outside of the rack 15 and the gears 14. Both the cover plate 3 and the cover plate 16 are used to protect the internal components and prevent dust and moisture from entering, thereby extending the service life of the components.

[0027] like Figure 6 As shown, it also includes a sealing strip 21. Each louver of the outer louver 13 has a sealing strip 21 bonded to its upper and lower ends in an alternating manner. When the louvers are closed, every two sealing strips 21 that are aligned vertically will contact each other to form a seal, preventing rainwater from penetrating and improving waterproof performance.

[0028] Initially, the inner louver 2 is closed, while the louvers are arranged horizontally. The collection frame 17, under the action of the spring 18, keeps the outer louver 13 in a normally open state for ventilation and lighting. When the inner louver 2 needs to be opened, the control system starts the motor 11. The output shaft of the motor 11 is connected to the lead screw 9 via the mounting base 10, causing the lead screw 9 to rotate. As the lead screw 9 rotates, the slider 7 moves along the direction of the lead screw 9. The slider 7 is connected to the lower part of the crank 5, and the movement of the slider 7 causes the crank 5 to move up and down. The up and down movement of the crank 5 is transmitted to each louver of the inner louver 2 via the connecting rod 4, causing the louvers of the inner louver 2 to open or close sequentially. The motor 11 drives the lead screw 9, realizing the automatic opening and closing of the inner louver 2, facilitating the adjustment of indoor light and ventilation. When it rains... Rainwater flows into the collection frame 17. As the rainwater accumulates, the collection frame 17 gradually descends under the action of gravity, squeezing the spring 18 below. The descent of the collection frame 17 causes the rack 15 connected to it to move downward. The rack 15 meshes with several gears 14 of the outer louver 13. The movement of the rack 15 causes the gears 14 to rotate. The gears 14 are connected to each blade of the outer louver 13. The rotation of the gears 14 causes the blades of the outer louver 13 to gradually close. The rainwater in the collection frame 17 will gradually be discharged through the drain hole 20. The inclined design of the bottom edge of the front of the support frame 1 and the drain hole 201 further ensure that the rainwater can be discharged smoothly and prevent rainwater from entering the support frame 1. When the blades are closed, the sealing strips 21 contact each other to form a seal and prevent rainwater from seeping in.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
