Description

Technical Field

[0001] This utility model relates to the field of building roof lighting technology, specifically a large-span skylight that facilitates natural ventilation. Background Technology

[0002] With the acceleration of urbanization, the demand for large public buildings and commercial facilities is constantly increasing. Large-span skylights, due to their ability to provide excellent natural lighting and visual effects, are gradually becoming an important component of modern architecture. However, ventilation is also a problem that needs to be considered and solved.

[0003] However, existing skylights are difficult to achieve the effect of both lighting and ventilation while also preventing insects, resulting in a lot of mosquito and insect disturbances in the indoor environment.

[0004] To address this issue, we propose a large-span skylight structure that promotes natural ventilation. To solve this problem, this application incorporates elastic netting on both sides of the frame on the inward-facing side of the folding window. When the folding window is closed, the elastic netting stretches, enlarging the mesh size to reduce sunlight obstruction and achieve good lighting. When the folding window is open, the elastic netting retracts, reducing the mesh size to a normal small opening, effectively blocking insects. The simultaneous use of elastic netting and insect netting effectively blocks insects when the folding window is open, and when the folding window is closed, a spiral spring retracts the insect netting, causing it to automatically retract onto a fixed axis, achieving an automatic retraction effect and eliminating the problem of retracting the insect netting, thus increasing practicality. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a large-span skylight structure that facilitates natural ventilation, thereby more effectively resolving the problems of hinge concealment and control of the opening and closing angle.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a large-span skylight that facilitates natural ventilation, comprising a skylight and a frame base set on the skylight, with a hinged folding window inside the base, characterized in that: an insect-proof net telescopic device is provided on the other side of the base connected to the folding window, the inner cavity of the insect-proof net telescopic device is provided with a fixed shaft, and a spiral spring and an insect-proof net are wound around the outside of the fixed shaft, the other side of the spiral spring and the insect-proof net are connected to the same side of a moving rod, and the other side of the moving rod is movably hinged to the folding window.

[0007] Furthermore, the base has a protrusion at its center, and slopes on both sides of the protrusion, with the folding window resting on the protrusion on both sides.

[0008] Furthermore, the protrusion has a cavity inside, and a threaded rod and a motor connected to it for transmission are installed in the cavity. The threaded rods are arranged in pairs, located in the inner cavities of the protrusion on both sides, and are connected to each other by belt drive.

[0009] Furthermore, the folding window consists of two windows hinged together.

[0010] Furthermore, the spiral spring is fixed to the inner side of the insect-proof net and is rolled up with the insect-proof net outside the fixed shaft.

[0011] Furthermore, the movable rod is provided with movable sleeves at both ends, which are threadedly connected to the threaded rods on both sides.

[0012] Furthermore, the width of the movable rod is greater than the width of the insect-proof net outlet of the insect-proof net telescopic device.

[0013] Furthermore, elastic netting is installed on both sides of the frame on the side of the folding window facing inward.

[0014] Furthermore, multiple folding windows can be installed depending on the actual size of the skylight.

[0015] Furthermore, the folding windows can be set according to the actual number of skylight slopes.

[0016] In summary, the present invention has the following main advantages:

[0017] 1. The motor drives the threaded rod in the raised inner cavity of the base to rotate. At the same time, the threaded rods on both sides operate through belt drive, causing the movable rod connected to it to move along the thread direction on the threaded rods on both sides. The movable rod is hinged to the folding window. While the movable rod moves, it can abut against the edge of the folding window and apply force to the folding window, so that the folding window folds along the raised trajectory. This makes it easier to apply force when the folding window is unfolded, avoids the situation where the two sides of the folding window resist each other when subjected to lateral forces, avoids damage to the folding window, and extends the service life of the structure.

[0018] 2: Folding windows can be set in multiple ways depending on the actual size of the skylight or the number of slopes of the skylight.

[0019] 3. When the folding window is opened, it forms a triangular shape, which leaves space on the sides, reducing the insect defense performance. To solve this problem, this application installs elastic netting on the two side frames of the folding window facing inward. When the folding window is closed, the elastic netting stretches, enlarging the mesh to reduce sunlight obstruction and achieve good lighting. When the folding window is open, the elastic netting retracts, reducing the mesh size to a normal small opening, effectively blocking insects.

[0020] 4. Using both elastic netting and insect netting simultaneously effectively blocks mosquitoes and insects when the folding window is open. When the folding window is closed, the insect netting is automatically rolled back by a spiral spring, eliminating the problem of rolling up the insect netting and increasing its practicality.

[0031] To more clearly and completely illustrate the technical solution of this utility model, the following description is provided in conjunction with the accompanying drawings.

[0032] Please refer to Figures 1-7This utility model proposes a large-span skylight structure 1 that is conducive to natural ventilation, including a frame-shaped base 2 set on the skylight 1, a folding window 3 set inside the base 2, the folding window 3 is composed of two window bodies connected by hinges, a protrusion 201 is provided at the center of the base 2, and the protrusion 201 has slopes on both sides.

[0033] The protrusion 201 has a cavity inside, and a threaded rod 8 and a motor 7 connected to it and playing a transmission role are installed in the cavity. The threaded rods 8 are arranged in pairs, located in the protrusions 201 on both sides, and are connected to each other by a belt 9 for transmission.

[0034] The folding window 3 is connected to the base 2 on one side by a hinge, and the other side of the base 2 connected to the folding window 3 is provided with an insect-proof net telescopic device 4. The inner cavity of the insect-proof net telescopic device 4 is provided with a fixed shaft 401, and a spiral spring 402 and an insect-proof net 403 are wound up on the outside of the fixed shaft 401.

[0035] The spiral spring 402 is fixed to one side of the insect-proof net 403 and is rolled up with the insect-proof net 403 on the outside of the fixed shaft 401.

[0036] The insect net 403 is connected at one end to one side of the movable rod 5, and the other side of the movable rod 5 is hinged to the folding window 3.

[0037] The movable rod 5 has movable sleeves at both ends, which are threadedly connected to the threaded rods 8 on both sides. When the folding window 3 is opened, the motor 7 drives the threaded rod 8 in the inner cavity of the protrusion 201 of the base 2 to rotate. At the same time, the threaded rods 8 on both sides are driven by the belt 9, so that the movable rod 5 connected to it moves on the threaded rods 8 on both sides in the direction of the thread. The movable rod 5 is hinged to the folding window 3. While the movable rod 5 is moving, it can abut against the edge of the folding window 3 and apply force to the folding window 3, so that the folding window 3 folds along the trajectory of the protrusion 201. This makes it easier to apply force when the folding window 3 is unfolded, avoids the situation where the two sides of the folding window 3 resist each other when subjected to lateral force, avoids damage to the folding window 3, and extends the service life of the structure.

[0038] While the moving rod 5 is in motion, the insect-proof net 403 inside the telescopic device 4 is pulled out, so that the area exposed when the folding window 3 is opened is covered by the insect-proof net 403, which can prevent mosquitoes from entering while providing ventilation.

[0039] When the folding window 3 is opened, it forms a triangular shape, leaving space on the sides and reducing its insect-repellent properties. To address this issue, this application incorporates elastic netting 6 on both sides of the frame facing inwards from the folding window 3. When the folding window 3 is closed, the elastic netting 6 stretches, enlarging the mesh size to reduce sunlight obstruction and improve light transmission. When the folding window 3 is open, the elastic netting 6 retracts, reducing the mesh size to a normal, small opening, effectively blocking insects.

[0040] The elastic net 6 and the insect net 403 work together to effectively block mosquitoes when the folding window 3 is open. When the folding window 3 is closed, the spiral spring 402 retracts the insect net 403, causing it to roll back onto the fixed shaft 401, achieving an automatic winding effect. This eliminates the problem of winding up the insect net 403 and increases its practicality.

[0041] After the insect net 403 is rolled back, the moving rod 5 will block the outlet of the insect net 403 of the insect net telescopic device 4, reducing the accumulation of mosquitoes and dust, and preventing a large number of mosquito corpses and dust from falling after the insect net 403 is opened, thus ensuring the cleanliness of the dust net to the greatest extent.

[0042] The number of folding windows 3 can be set according to the actual size of the skylight 1 or according to the actual number of slopes of the skylight 1.

[0043] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
