Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground ventilation technology, specifically a natural ventilation and lighting structure for basements. Background Technology
[0002] A basement is a room in a building located below the outdoor ground level. Constructing basements below the ground floor is a common practice in urban development, as it increases the utilization rate of building land. To address the issues of lighting and ventilation in basements, ventilation shafts are typically installed, allowing outside air and light to enter the basement. To facilitate ventilation, louvers are installed on the ventilation shafts; the rotation of the louvers not only allows for ventilation within the shaft but also facilitates airflow between the inside and outside of the shaft.
[0003] However, existing venetian blinds require users to pull a ladder rope to control the slats when flipping them. As the venetian blinds are used for a longer period of time, friction occurs between the ladder rope and the slats during the pulling process. With each pull, the ladder rope that controls the slat flipping will wear down and may even break, thus affecting its lifespan. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a basement natural ventilation and lighting structure that has the advantages of replacing the ladder rope used for adjusting the folding angle of louvers, reinforcing the stability of louvers after folding, and improving the practicality of louvers, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a basement natural ventilation and lighting structure, including a ventilation shaft body. Four windows are evenly distributed on the outer wall of the upper end of the ventilation shaft body. Each window has several louver bodies installed inside. A rotating shaft is fixedly sleeved on the inner wall of each louver body, and both ends of the rotating shaft are rotatably connected to the inner wall of the ventilation shaft body. A movable component for controlling the opening and closing of the louver bodies is provided in the middle of the outer wall of the rotating shaft. A telescopic rod located inside the ventilation shaft body is fixedly installed at the lower end of the movable component. A fixed rod located below the movable component is movably sleeved on the outer wall of the telescopic rod. An adjusting component for adjusting the raising and lowering of the movable component is provided inside the lower end of the telescopic rod. A glass window is fixedly installed at the upper end of the ventilation shaft body.
[0006] Preferably, the movable component includes a spur gear and a ruler strip. The inner side of the spur gear meshes with the outer teeth of the ruler strip. The inner wall of the spur gear is fixedly sleeved with the outer wall of the middle part of the rotating shaft. A partition plate located outside the spur gear is movably sleeved on the outer wall of the rotating shaft, and the upper and lower ends of the partition plate are respectively fixedly connected to the upper and lower sides of the inner wall of the window. A limit rod is fixedly installed on the inner side of the ruler strip. A housing is movably sleeved on the outer wall of the limit rod. An upper mounting plate is fixedly installed on the upper and lower ends of the housing, and the end of the upper mounting plate away from the housing is fixedly connected to the inner wall of the ventilation shaft body. The lower end of the ruler strip is fixedly connected to the upper end of the telescopic rod.
[0007] Preferably, an indicator needle located outside the fixed rod is fixedly installed on the inner side of the upper end of the telescopic rod, and a number of sliders are evenly distributed on the outer wall of the lower end of the telescopic rod, with the end of the slider away from the telescopic rod slidingly connected to the inner wall of the fixed rod.
[0008] Preferably, a scale line located outside the indicator needle is fixedly installed on the inner side of the fixing rod, and lower mounting plates are fixedly installed on both sides of the fixing rod, with the end of the lower mounting plate away from the fixing rod being fixedly connected to the inner wall of the ventilation shaft body.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model achieves the flipping function of the louver body by coordinating the ventilation shaft body, the louver body, the movable component, and the adjustment component. The adjustment component drives the movement of the movable component through the connection of the telescopic rod, which replaces the method of controlling the louver body with ladder rope. This avoids the interference of ladder rope breakage after wear and tear on the normal use of the louver body, thus maintaining the practicality of the louver body.
[0012] 2. This utility model utilizes the cooperation between the louver body, scale line, indicator needle, and telescopic rod.

[0015] 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.
[0016] Please see Figure 1 , Figure 3 and Figure 4A basement natural ventilation and lighting structure includes a ventilation shaft body 1. Four windows 2 are evenly distributed on the outer wall of the upper end of the ventilation shaft body 1. Each window 2 has several louvered bodies 3 installed inside. When flipped, the louvered bodies 3 not only provide ventilation but also reduce rainwater ingress into the ventilation shaft body 1. A rotating shaft 4 is fixedly sleeved on the inner wall of the louvered body 3, with both ends of the rotating shaft 4 rotatably connected to the inner wall of the ventilation shaft body 1. The rotating shaft 4 connects the louvered body 3 to a movable component 5. A movable component 5 for controlling the opening and closing of the louvered body 3 is located in the middle of the outer wall of the rotating shaft 4. A telescopic rod 6 located inside the ventilation shaft body 1 is fixedly installed at the lower end of the movable component 5. A fixed rod 7 located below the movable component 5 is movably sleeved on the outer wall of the telescopic rod 6. An adjusting component 8 for adjusting the raising and lowering of the movable component 5 is located inside the lower end of the telescopic rod 6. A glass window 9 is fixedly installed at the upper end of the ventilation shaft body 1, providing lighting to the ventilation shaft body 1.
[0017] The movable component 5 includes a spur gear 501 and a ruler strip 502. The inner side of the spur gear 501 meshes with the outer teeth of the ruler strip 502. Due to the meshing connection between the ruler strip 502 and the spur gear 501, the linear motion of the ruler strip 502 drives the circumferential rotation of the spur gear 501. The rotation of the spur gear 501 drives the flap of the louver body 3 through the connection of the rotating shaft 4. The inner wall of the spur gear 501 is fixedly sleeved with the outer wall of the middle part of the rotating shaft 4, and the outer wall of the rotating shaft 4 is movably sleeved with... A partition 10 is located outside the spur gear 501, and the upper and lower ends of the partition 10 are fixedly connected to the upper and lower sides of the inner wall of the window 2, respectively. A limit rod 11 is fixedly installed on the inner side of the ruler strip 502. A housing 12 is movably sleeved on the outer wall of the limit rod 11. An upper mounting plate 13 is fixedly installed on the upper and lower ends of the housing 12, and the end of the upper mounting plate 13 away from the housing 12 is fixedly connected to the inner wall of the ventilation shaft body 1. The lower end of the ruler strip 502 is fixedly connected to the upper end of the telescopic rod 6.
[0018] Please see Figure 2 and Figure 5 An indicator needle 15 located outside the fixed rod 7 is fixedly installed on the inner side of the upper end of the telescopic rod 6. Several sliders 17 are evenly distributed on the outer wall of the lower end of the telescopic rod 6, and the end of the slider 17 away from the telescopic rod 6 is slidably connected to the inner wall of the fixed rod 7.
[0019] A scale line 14 located outside the indicator needle 15 is fixedly installed on the inner side of the fixed rod 7. The movement of the telescopic rod 6 causes the indicator needle 15 to move on the scale line 14, which can be used to observe the telescopic length value of the telescopic rod 6. The louver body 3 is flipped to a slope with the inside higher than the outside. When the indicator needle 15 points to the middle of the scale line 14, the louver body 3 is in a horizontal state with the ground. When the indicator needle 15 points to the bottom of the scale line 14, the louver body 3 is in a state with the inside higher than the outside. When the indicator needle 15 is at the top of the scale line 14, the louver body 3 is in a state with the inside lower than the outside. The lower mounting plate 16 is fixedly installed on both sides of the fixed rod 7, and the end of the lower mounting plate 16 away from the fixed rod 7 is fixedly connected to the inner wall of the ventilation shaft body 1.
[0020] Please see Figure 6 and Figure 4 The adjusting component 8 includes a ball nut 801 and a ball screw 802. The inner wall of the ball nut 801 is threadedly connected to the outer wall of the ball screw 802. After the rotary motor 18 is turned on, it drives the ball screw 802 to rotate. Due to the threaded connection between the ball screw 802 and the ball nut 801, the movement of the ball nut 801 drives the telescopic rod 6 to extend and retract within the fixed rod 7. The outer end of the ball nut 801 is fixedly connected to the inner wall of the telescopic rod 6.
[0021] A rotary motor 18 located below the fixed rod 7 is fixedly installed at the lower end of the ball screw 802, and a reducer is provided on the output shaft of the rotary motor 18. The reducer is used to adjust the speed of the output shaft of the rotary motor 18. A housing 19 is fixedly installed on the outer wall of the rotary motor 18, and the upper end of the housing 19 is fixedly connected to the lower end of the fixed rod 7.
[0022] Working principle: In use, first, turn on the power to the rotary motor 18. After the rotary motor 18 is turned on, it drives the ball screw 802 to rotate. Due to the threaded connection between the ball screw 802 and the ball nut 801, the movement of the ball nut 801 simultaneously drives the telescopic rod 6 to extend and retract within the fixed rod 7. When the ball nut 801 moves upward on the ball screw 802, the telescopic rod 6 moves upward on the fixed rod 7. Simultaneously, the movement of the telescopic rod 6 drives the ruler strip 502 to move upward. Due to the meshing connection between the ruler strip 502 and the spur gear 501, the linear movement of the ruler strip 502 drives the circumferential rotation of the spur gear 501. The rotation of the spur gear 501 is transmitted through the rotation of the rotary motor 18. The connection of shaft 4 drives the louver body 3 to flip. Then, the movement of telescopic rod 6 causes the indicator needle 15 to move on the scale line 14, which can be used to observe the telescopic length value of telescopic rod 6. The louver body 3 is flipped to an inclined surface with the inside higher than the outside. When the indicator needle 15 points to the middle of the scale line 14, the louver body 3 is in a horizontal state with the ground. When the indicator needle 15 points to the bottom of the scale line 14, the louver body 3 is in a state with the inside higher than the outside. When the indicator needle 15 is at the top of the scale line 14, the louver body 3 is in a state with the inside lower than the outside. Finally, the flipped louver body 3 can not only play a role in ventilation, but also reduce rainwater from entering the interior of the ventilation shaft body 1.
