Description

Technical Field

[0001] This invention relates to the field of skylight technology, and in particular to a skylight for prefabricated buildings. Background Technology

[0002] A light well is a well-shaped opening in the exterior wall of a basement, enclosed by a retaining wall, that allows light to pass through. The bottom of the light well is lower than the windowsill and should have drainage facilities. Light wells primarily address the problem of poor lighting in individual rooms due to the height of the building.

[0003] Chinese patent CN216690817U discloses a skylight window, which includes: a base frame, multiple pressure strips, and multiple pressure plates; the base frame is set on a base and includes multiple mounting parts; each pressure strip is set on a mounting part and partially covers the base frame; each pressure plate is set above a pressure strip and the base frame is set below the pressure strip, and the pressure plate, pressure strips and base frame form a U-shaped groove structure facing the composite glass. A buffer pad is provided in the U-shaped groove structure, and the buffer pad wraps around the end of the composite glass. This skylight window can improve the overall sealing of the skylight window and the protection of the composite glass.

[0004] Regarding the aforementioned technologies, in existing technologies, construction workers use composite glass to seal the well openings of buildings, which also serves as a means of lighting. However, due to environmental limitations, the air circulation in the underground rooms of prefabricated buildings is generally not strong. Using the existing light well technology will further reduce the air circulation in the underground rooms of prefabricated buildings, making it impossible for odors to dissipate in time and reducing the comfort of the underground rooms of prefabricated buildings. Therefore, it is necessary to improve the existing airtight light well technology. Summary of the Invention

[0005] To improve the air circulation in the underground rooms of prefabricated buildings, this application provides a skylight for prefabricated buildings.

[0006] This application provides the following technical solution for skylights in prefabricated buildings: A prefabricated building skylight includes a window frame, on which a fixed plate, a flip plate, and a movable plate are disposed. The fixed plate is connected to the window frame, and the flip plate is rotatably connected to the window frame. A limiting component is disposed on the window frame to restrict the rotation of the flip plate. The movable plate moves between the fixed plate and the flip plate. An adjusting component is disposed on the window frame to adjust the position of the movable plate. The fixed plate, the flip plate, and the movable plate are all transparent glass plates. Ventilation holes are opened on the fixed plate and the flip plate, and ventilation holes are opened on the movable plate at positions corresponding to the ventilation holes.

[0007] By adopting the above technical solution, during ventilation, construction workers align the vents with the air vents to allow outside air to smoothly enter the underground room, achieving air circulation. During rain, workers adjust the position of the movable panel to offset the vents from the air vents, effectively blocking the air vents and providing rain protection. Workers can adjust the position of the movable panel using the adjusting components. During ventilation, they can adjust the opening and closing size of the vents according to actual needs, making ventilation adjustment in the underground room more user-friendly and achieving smooth ventilation in the prefabricated building's underground room. During rain, workers can adjust the components to offset the vents from the air vents, preventing air from entering the air vents. Simultaneously, the movable panel, flip panel, and fixed panel are all made of transparent glass, ensuring sufficient lighting in the underground room and improving the comfort of the underground room during assembly.

[0008] Optionally, the window frame includes a fixed frame and a mounting frame. The fixed plate, the flip plate, and the movable plate are all disposed within the mounting frame. The mounting frame is slidably fitted onto the fixed frame. A locking assembly is provided on the fixed frame. The locking assembly includes a rotating shaft, a locking disc, and a locking block. The rotating shaft is rotatably connected to the mounting frame. The locking disc is connected to one end of the rotating shaft. The locking block is connected to the fixed frame. The locking block is a T-shaped block. The annular wall of the locking disc has an clearance groove and a locking arc groove. The locking arc groove is a T-shaped groove. The clearance groove communicates with the locking arc groove. The locking block is slidably fitted within the locking arc groove. The reference direction is from the clearance groove to the inner end of the locking arc groove. The distance between the two opposite inner sidewalls of the locking arc groove gradually decreases. The fixed frame has a U-shaped groove. When locking the mounting frame, the rotating shaft is located within the U-shaped groove, and the locking disc fits against the fixed frame.

[0009] By adopting the above technical solution, and by setting up a fixed frame and an installation frame, maintenance between the flip plate and the fixed plate is made easier. When locking the installation frame, the construction worker inserts the rotating shaft into the U-shaped groove, so that the locking disc fits against the fixed frame, and the installation frame fits against the fixed frame. At the same time, the locking block smoothly enters the clearance groove. Then, the rotating shaft is rotated, which drives the locking disc to rotate, so that the locking block enters the locking arc groove until the two inner walls of the locking arc groove are pressed against the locking block, thus achieving the effect of locking the installation frame.

[0010] Optionally, the adjustment assembly includes a drive shaft, a rotating plate, and a movable column. The mounting frame has a mounting cavity. The drive shaft is rotatably connected to the mounting frame. The rotating plate is connected to the drive shaft and located in the mounting cavity. The rotating plate has a pushing arc groove. The movable column is connected to the movable plate and slidably engages in the pushing arc groove. The mounting frame is provided with a clamping assembly to restrict the rotation of the drive shaft.

[0011] By adopting the above technical solution, when it rains, the construction workers rotate the drive shaft, which drives the rotating plate to rotate. By pushing the arc groove and the moving column to cooperate, the moving column moves, which in turn moves the moving plate. This causes the ventilation holes to be staggered from the air vents and cooperates with the clamping components to increase the friction force on the drive shaft and reduce the possibility of the moving plate moving, thus achieving the effect of rain shelter in the underground room.

[0012] Optionally, the clamping assembly includes a clamping block, a pull rod, and a clamping spring. The pull rod is slidably fitted on the mounting frame and is a rectangular rod. The clamping block is connected to one end of the pull rod and is located inside the mounting cavity. The clamping block has a clamping groove that matches the shape of the drive shaft and fits against the surface of the drive shaft. The other end of the pull rod is connected to a stop block. The clamping spring is sleeved on the pull rod and is located between the clamping block and the inner wall of the mounting cavity.

[0013] By adopting the above technical solution, when the drive shaft is restricted from rotating, the clamping block is subjected to the force of the clamping spring to clamp the drive shaft, thereby restricting the rotation of the drive shaft and reducing the possibility of the drive shaft rotating, thus restricting the movement of the moving plate.

[0014] Optionally, a plurality of abutting teeth are fixedly connected in the abutting groove, and a plurality of fixed teeth are connected to the surface of the drive shaft, wherein the abutting teeth and the fixed teeth mesh.

[0015] By adopting the above technical solution, construction workers further increased the friction between the clamping block and the drive shaft by utilizing the cooperation of the clamping teeth and the fixing teeth, thereby further reducing the possibility of the moving plate moving.

[0016] Optionally, the limiting component includes a fixed post, a movable seat, a rotating block, a traction spring, and a return torsion spring. The fixed post is connected to the flip plate. The mounting frame has a locking groove at the position corresponding to the fixed post. The movable seat is slidably fitted in the locking groove. The traction spring is connected between the mounting frame and the movable seat. A connecting shaft is connected to the rotating block. The rotating block is rotatably connected to the movable seat through the connecting shaft. The return torsion spring is sleeved on the connecting shaft and connected between the movable seat and the rotating block. The rotating block is also provided with an abutting inclined surface and a snap-fit ​​groove. When the flip plate is limited, the fixed post snaps into the snap-fit ​​groove.

[0017] By adopting the above technical solution, when the rotating plate is restricted from rotating, the construction personnel close the flip plate, allowing the fixed column to enter the locking groove. Then, they push the moving seat, compressing the traction spring and causing the rotating block to move. The rotating block then moves against the inclined surface and against the fixed column, causing it to rotate. The reset torsion spring is compressed until the fixed column enters the locking groove. The moving seat is then released, and it moves in the opposite direction under the force of the traction spring, causing the fixed column to contact the inner wall of the locking groove. This restricts the degree of freedom of the flip plate and achieves the effect of restricting the rotation of the flip plate.

[0018] Optionally, the movable plate has a drainage cavity on its side wall near the fixed plate, the fixed plate has a drainage groove on its side wall near the movable plate, and the mounting cavity has several drainage holes on its side wall.

[0019] By adopting the above technical solution, during rain, there is a possibility that rainwater may flow into the skylight through the gap between the movable panel and the flip panel. Construction workers utilize the combined use of a drainage cavity and drainage channel to divert rainwater, allowing leaked rainwater to smoothly enter the installation cavity. The rainwater then exits through the drainage hole into the window frame, reducing the possibility of rainwater leaking into the basement.

[0020] Optionally, a lighting adjustment assembly is provided on the fixed frame. The lighting adjustment assembly includes an adjustment plate, a rotating gear, and a moving rack. A plurality of adjustment shafts are rotatably connected to the fixed frame. The adjustment plate is connected to the adjustment shaft. The rotating gear is connected to one end of the adjustment shaft. The moving rack is slidably engaged with the mounting frame and meshes with the rotating gear. An adjustment rod is connected to the moving rack. A sliding groove is opened on the mounting frame at the position corresponding to the adjustment rod. The adjustment rod is slidably engaged in the sliding groove. When the light from the light well is blocked, the plurality of adjustment plates cover the fixed plate.

[0021] By adopting the above technical solution, when blocking the light from the skylight, the construction workers push the adjusting rod, which moves the moving rack, causing several rotating gears to rotate simultaneously, which in turn drives the adjusting shaft to rotate, causing the adjusting plate to rotate. Several adjusting plates cover the area of ​​the fixed plate, thereby blocking the external light and achieving the effect of blocking the light from the skylight.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During ventilation, construction workers align the vent holes with the ventilation openings to allow outside air to enter the underground room smoothly, achieving air circulation. During rain, workers adjust the position of the movable panel to offset the vent holes from the ventilation openings, effectively blocking them and preventing rain damage. The workers utilize adjusting components to control the position of the movable panel. During ventilation, they can adjust the opening and closing size of the vent holes according to actual needs, making ventilation in the underground room more user-friendly and achieving smooth ventilation in the prefabricated building's underground room. During rain, workers use adjusting components to offset the vent holes from the ventilation openings, preventing air from entering the ventilation openings. Simultaneously, the movable panel, flip panel, and fixed panel are all made of transparent glass, ensuring ample natural light in the underground room and improving comfort during assembly. 2. By setting up a fixed frame and an installation frame, maintenance between the flip plate and the fixed plate is made easier. When locking the installation frame, the installer inserts the rotating shaft into the U-shaped groove, so that the locking disc fits against the fixed frame and the installation frame fits against the fixed frame. At the same time, the locking block smoothly enters the clearance groove. Then, the rotating shaft is rotated, which drives the locking disc to rotate, so that the locking block enters the locking arc groove until the two inner walls of the locking arc groove are pressed against the locking block, thus achieving the effect of locking the installation frame. 3. To restrict the rotation of the rotating plate, the construction worker closes the flip plate, allowing the fixed column to enter the locking groove. Then, the moving seat is pushed, compressing the traction spring and causing the rotating block to move. The rotating block then moves against the inclined surface and against the fixed column, causing it to rotate. The reset torsion spring is compressed until the fixed column enters the locking groove. The moving seat is then released, and it moves in the opposite direction under the force of the traction spring, causing the fixed column to contact the inner wall of the locking groove. This restricts the degree of freedom of the flip plate and achieves the effect of restricting its rotation. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0035] This application discloses a skylight for prefabricated buildings. (Refer to...) Figure 1 , Figure 2 and Figure 3 The prefabricated building skylight includes a window frame 1, which includes a fixed frame 11 and a mounting frame 12. The fixed frame 11 is a portal frame, and a T-shaped slide bar is fixedly connected to the mounting frame 12. The T-shaped slide bar is slidably fitted onto the fixed frame 11. The mounting frame 12 is located at the opening of the fixed frame 11, and a mounting cavity 121 is provided on the side wall of the mounting frame 12 near the fixed frame 11.

[0036] Reference Figure 2 and Figure 3The fixed frame 11 is provided with several sets of locking components 2. In this embodiment, two sets are used as an example. The locking components 2 include a rotating shaft 21, a locking disc 22, and a locking block 23. A U-shaped groove 111 is opened on the fixed frame 11. The rotating shaft 21 is rotatably connected to the mounting frame 12 and is located in the U-shaped groove 111. The locking disc 22 is fixedly connected to one end of the rotating shaft 21. An avoidance groove 221 and a locking arc groove 222 are opened on the annular wall of the locking disc 22. The locking arc groove 222 is a T-shaped groove. The avoidance groove 221 communicates with the locking arc groove 222. Taking the direction from the avoidance groove 221 to the inner bottom wall of the locking arc groove 222 as a reference direction, the distance between the locking arc groove 222 and the two inner side walls gradually decreases. The locking block 23 is a T-shaped block and is fixedly connected to the fixed frame 11. A rotating knob is fixedly connected to the other end of the rotating shaft 21.

[0037] When locking the mounting frame 12, the installer slides the rotating shaft 21 into the U-shaped groove 111, so that the locking disc 22 fits against the fixed frame 11, and at the same time, the locking block 23 enters the clearance groove 221. Then, the rotating knob is rotated to make the rotating shaft 21 rotate, which drives the locking disc 22 to rotate, so that the locking block 23 enters the locking arc groove 222 until the locking block 23 is pressed against the two inner side walls of the locking arc groove 222, thus achieving the effect of locking the mounting frame 12.

[0038] Reference Figure 4 and Figure 5 The fixed frame 11 contains a fixed plate 3, a movable plate 4, and a flip plate 5. The fixed plate 3 is fixedly connected to the fixed frame 11, one end of the flip plate 5 is hinged within the fixed frame 11, and the movable plate 4 is slidably fitted between the flip plate 5 and the fixed plate 3. The fixed plate 3, movable plate 4, and flip plate 5 are all transparent glass plates. Both the flip plate 5 and the fixed plate 3 have several ventilation holes 51. The movable plate 4 has ventilation holes 41 at positions corresponding to the ventilation holes 51, and the diameter of the ventilation holes 41 is larger than the diameter of the ventilation holes 51. When the movable plate 4 is in its initial position, the ventilation holes 41 are aligned with the ventilation holes 51.

[0039] Reference Figure 6 and Figure 7 An adjustment assembly 6 is provided on the mounting frame 12. The adjustment assembly 6 includes a drive shaft 61, a rotating plate 62, and a moving column 63. The drive shaft 61 is rotatably connected to the mounting frame 12. The rotating plate 62 is fixedly connected to the bottom end of the drive shaft 61 and located inside the mounting cavity 121. The rotating plate 62 has a push arc groove 621. The moving column 63 is fixedly connected to the moving plate 4 and slides within the push arc groove 621. An adjustment knob is fixedly connected to the top end of the drive shaft 61.

[0040] Reference Figure 6 and Figure 7A clamping assembly 7 is provided inside the mounting cavity 121. The clamping assembly 7 includes a clamping block 71, a pull rod 72, and a clamping spring 73. The pull rod 72 is a rectangular rod that slides on the mounting frame 12. The clamping block 71 is fixedly connected to one end of the pull rod 72 and is located inside the mounting cavity 121. A clamping groove is formed on the side wall of the clamping block 71 near the moving plate 4, and several clamping teeth 711 are fixedly connected to the inner wall of the clamping groove. Several fixing teeth 611 are fixedly connected to the surface of the drive shaft 61, and the clamping teeth 711 mesh with the fixing teeth 611. The clamping spring 73 is sleeved on the pull rod 72 and is located between the clamping block 71 and the inner wall of the mounting cavity 121. A stop block 721 is fixedly connected to the other end of the pull rod 72.

[0041] When adjusting the position of the movable plate 4, the construction worker pulls the stop block 721, causing the clamping block 71 to move and the clamping spring 73 to be compressed. Then, the adjustment knob is turned to make the drive shaft 61 rotate, which drives the rotating plate 62 to rotate, causing the movable column 63 to move and the adjustment plate 91 to move, so that the vent hole 41 and the ventilation hole 51 are misaligned. After the adjustment plate 91 moves to the designated position, the stop block 721 is released, and the clamping block 71 moves in the opposite direction under the force of the clamping spring 73, so that the clamping tooth 711 and the fixed tooth 611 mesh, thus achieving the effect of adjusting the position of the movable plate 4.

[0042] Reference Figure 8 and Figure 9 The mounting frame 12 is provided with several limiting components 8. In this embodiment, two sets are used as examples. The limiting components 8 include a fixed post 81, a movable seat 82, a rotating block 83, a traction spring 84, and a return torsion spring 85. The fixed post 81 is fixedly connected to one end of the flip plate 5 near the mounting frame 12. The mounting frame 12 has a locking groove at the position corresponding to the fixed post 81, and the movable seat 82 is slidably fitted in the locking groove. Connecting plates are fixedly connected to both the movable seat 82 and the mounting frame 12, and the traction spring 84 is disposed between the two connecting plates. A connecting shaft 831 is fixedly connected to the rotating block 83, and the rotating block 83 is rotatably connected to the movable seat 82 through the connecting shaft 831. The rotating block 83 is also provided with an abutting inclined surface 832 and a snap-fit ​​groove 833. The return torsion spring 85 is sleeved on the connecting shaft 831 and fixedly connected between the movable seat 82 and the rotating block 83.

[0043] When the flip plate 5 is restricted, the construction personnel close the flip plate 5, so that the fixed column 81 enters the locking groove, push the moving seat 82, and the inclined surface 832 abuts against the fixed column 81, so that the rotating block 83 rotates until the fixed column 81 enters the snap-fit ​​groove 833. The rotating block 83 is reset by the force of the reset torsion spring 85, the traction spring 84 is compressed, the moving seat 82 is released, and the fixed column 81 is snapped into the snap-fit ​​groove 833, thus achieving the effect of restricting the flip plate 5.

[0044] Reference Figure 4 and Figure 5To improve the sealing between the movable plate 4 and the flip plate 5, several sealing gaskets 42, which are rubber gaskets, are embedded on the surface of the movable plate 4 at the positions corresponding to the vent holes 51. When it rains, the sealing gaskets 42 block the vent holes 51. A drainage cavity 43 is opened on the side wall of the movable plate 4 near the fixed plate 3, and a drainage groove 31 is opened on the side wall of the fixed plate 3 near the drainage cavity 43. Several drainage holes 122 are opened on the mounting frame 12.

[0045] During drainage, rainwater flows along the side walls of the drainage cavity 43 and the drainage channel 31, enters the installation cavity 121, and finally flows out through the drainage hole 122.

[0046] Reference Figure 10 A lighting adjustment component 9 is provided on the fixed frame 11. The lighting adjustment component 9 includes an adjustment plate 91, a rotating gear 92, and a moving rack 93. Two mounting plates are fixedly connected to the fixed frame 11, and several adjustment shafts are rotatably connected between the two mounting plates. The adjustment plate 91 is fixedly connected to the adjustment shafts and is parallel to the adjustment shafts. The rotating gear 92 is fixedly connected to one end of the adjustment shafts.

[0047] Reference Figure 6 , Figure 8 and Figure 10 A limiting slide bar is fixedly connected to the movable rack 93. The limiting slide bar is a T-shaped bar and slides on the mounting frame 12, meshing with the rotating gear 92. An adjusting rod 931 is fixedly connected to the limiting slide bar. A sliding groove is opened on the mounting frame 12 at the position corresponding to the adjusting rod 931, and the adjusting rod 931 slides in the sliding groove.

[0048] When the skylight is closed, the construction workers push the adjusting rod 931, which moves the moving rack 93, causing several rotating gears 92 to rotate simultaneously, which in turn drives the adjusting plate 91 to rotate until several adjusting plates 91 cover the fixed plate 3, thus achieving the effect of closed skylight.

[0049] The implementation principle of a prefabricated building skylight in this application embodiment is as follows: When ventilating the underground room, the construction workers align the vent 41 with the ventilation hole 51 to connect the underground room to the outside. When the ventilation intensity is reduced, the construction workers pull the stop block 721, causing the pull rod 72 to move, which in turn moves the clamping block 71. By rotating the adjustment knob, the drive shaft 61 is rotated, causing the rotating plate 62 to rotate, which in turn moves the moving plate 4, causing the vent 41 to partially offset the ventilation hole 51. Then, the stop block 721 is released, the pull rod 72 moves in the opposite direction, and the clamping block 71 moves. The clamping teeth 711 mesh with the fixed teeth 611 to restrict the moving plate 4. If the underground room is to be de-ventilated, the moving plate 4 can be moved until the sealing gasket 42 is aligned with the ventilation hole 51.

[0050] Construction workers use adjusting component 6 to adjust the position of the movable plate 4. During ventilation, they can adjust the opening and closing size of the vent 51 according to actual needs, making ventilation adjustment in the underground room more user-friendly and achieving smooth ventilation in the prefabricated building's underground room. During rain, workers use adjusting component 6 to offset the vent 41 from the vent 51, preventing air from entering the vent 51. Simultaneously, the movable plate 4, the flip plate 5, and the fixed plate 3 are all transparent glass panels, ensuring ample lighting in the underground room and improving comfort during assembly.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
