Description

Technical Field

[0001] This utility model belongs to the field of ventilation skylight technology, and in particular relates to a solar ventilation skylight that is easy to disassemble. Background Technology

[0002] A ventilation skylight is a window device installed on the top or roof of a building, primarily used to promote air circulation and indoor ventilation.

[0003] For example, Chinese patent CN222252816U discloses a roof ventilation skylight. This device, through the setting of a transmission mechanism, can drive a conveyor belt to move left and right according to the weather by rotating a forward and reverse motor, thereby realizing the control of opening and closing the window.

[0004] The aforementioned patent has the following problems: This patent has some drawbacks in its use. For example, the glass and window of the device are molded as a single piece. If different types of glass are needed depending on the environment (such as using UV-resistant glass to reduce penetration in summer, or using dimming or soundproof glass in offices to increase environmental comfort), the entire window needs to be disassembled and replaced, reducing the convenience of glass replacement. In view of this, we propose a solar ventilation skylight that is easy to disassemble. Utility Model Content

[0005] The purpose of this invention is to provide a solar ventilation skylight that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a solar ventilation skylight that is easy to disassemble, comprising: A ventilation frame, the top of which is hinged to a window frame; Two placement slots are respectively opened on both sides of the inner wall of the window frame. A glass body is provided at the top of the two placement slots. A moving slot is opened inside the window frame. Moving plates are slidably connected to both sides of the moving slot. Adaptive inclined surfaces are opened at the adjacent ends of the two moving plates. A wedge block is slidably connected between the two adaptive inclined surfaces. Limiting plates are fixedly connected to the adjacent sides of the two moving plates. The two limiting plates pass through the window frame and are set on the top sides of the glass body. A pushing component is disposed on one side of the window frame and is used to drive the wedge block to move; A reset assembly is disposed on both sides inside the movable slot and is used to drive the two movable plates to reset.

[0007] In this technical solution, by pushing the component to move the wedge block, the wedge block, with the help of the adapting inclined surface, pushes the two moving plates to slide along the moving groove and move away from each other. At the same time, the two moving plates drive the two limiting plates away from each other and store the limiting plates inside the moving groove. At this point, the limitation at the top of the glass body disappears, and the glass body can be removed through the placement groove, which improves the convenience of glass body replacement. After the glass body is replaced, by pushing the component to move the wedge block, the wedge block releases the pressure on the adapting inclined surface. At this time, the reset component pushes the two moving plates to slide closer together along the moving groove. At the same time, the two moving plates drive the two limiting plates to slide out of the moving groove and move to the top two sides of the glass body, thereby completing the limiting installation operation of the glass body.

[0008] In the above technical solution, the driving component further includes: The housing is fixedly connected to one side of the window frame. An extension block and a push block are slidably connected inside the housing. One side of the extension block has a first sliding slope, and one side of the push block has a second sliding slope. The first and second sliding slopes are slidably engaged. A second extension rod is fixedly connected to the inner wall of the housing. One end of the second extension rod is fixedly connected to one side of the push block. A connecting rod is fixedly connected to one side of the extension block. One end of the connecting rod passes through the window frame and is fixed to one side of a wedge-shaped block. A second spring is fitted onto the outer wall of the connecting rod. One end of the second spring is fixedly connected to one side of the extension block, and the other end of the second spring is fixedly connected to the window frame.

[0009] In this technical solution, the telescopic rod 2 is activated to drive the push block to move. The push block moves the telescopic block by means of the sliding engagement between the sliding inclined surface 1 and the sliding inclined surface 2. While the telescopic block compresses the spring 2, it also drives the connecting rod and the wedge block to move in sequence. The wedge block uses the matching inclined surface to complete the squeezing and moving of the moving plate. After the glass body is installed, the telescopic rod 2 is activated to retract the push block. At this time, the compressed spring 2 pushes the telescopic block back to its position. The telescopic block then drives the connecting rod and the wedge block to their positions in sequence and releases the squeezing of the moving plate.

[0010] In the above technical solution, the reset component further includes: Several springs are provided, one end of each spring is fixedly connected to both sides of the interior of the moving groove, and the other end of each spring is fixedly connected to the side of the two moving plates that is far away from each other. Several spring telescopic rods are fixedly connected to both sides of the interior of the moving groove, and the multiple spring telescopic rods are located inside the multiple springs.

[0011] In this technical solution, when the wedge block pushes the two moving plates along the moving groove and away from each other with the help of the adapting inclined surface, the two moving plates will compress several spring telescopic rods and spring 1. When the wedge block returns to its position and releases the pressure on the moving plates, the elastic force of the several spring telescopic rods and spring 1 that were compressed will be released and push the two moving plates to drive the two limiting plates to slide out of the moving groove to limit the glass body.

[0012] In the above technical solution, further, a number of mounting seats are fixedly connected to the bottom of the outer wall of the ventilation frame, two mounting brackets are fixedly connected to the edge of the outer wall of the ventilation frame, a photovoltaic panel is fixedly connected to the top of the two mounting brackets, and a battery is fixedly connected to the bottom of the photovoltaic panel.

[0013] In this technical solution, the mounting base is used for the fixed installation of the ventilation frame; the mounting bracket is used for the installation of the photovoltaic panel; and the storage battery is used for storing light energy, thereby increasing the energy-saving effect of the device.

[0014] In the above technical solution, further, a base is fixedly connected to the inner side wall of the ventilation frame, a connecting seat is fixedly connected to the bottom of the window frame, and a telescopic rod is rotatably connected inside the base, with one end of the telescopic rod rotatably connected to the inside of the connecting seat.

[0015] In this technical solution, the window frame is rotated along the ventilation frame by activating the telescopic rod, thereby achieving ventilation inside the ventilation frame.

[0016] In the above technical solution, the top cross-section of the moving groove is U-shaped, the top of the moving plate is L-shaped, the top of the telescopic block and the pushing block are right-angled triangles, and the top of the wedge block is trapezoidal.

[0017] In this technical solution, the sliding of the moving plate inside the moving groove is achieved by the L-shaped moving plate and the U-shaped moving groove being adapted to each other; the mutual driving between the telescopic block and the pushing block is achieved by the right-angled triangular inclined surface of the telescopic block and the pushing block being in contact and sliding cooperation; and the squeezing and pushing of the moving plate by the wedge block is achieved by the sliding cooperation between the trapezoidal inclined surface of the wedge block and the adapting inclined surface.

[0018] In the above technical solution, the photovoltaic panel is further electrically connected to the battery, and the battery is electrically connected to the first telescopic rod and the second telescopic rod in sequence.

[0019] In this technical solution, solar energy is converted into electrical energy by photovoltaic panels and stored in a battery. The battery then supplies power to telescopic rod one and telescopic rod two, thereby enabling the normal use of the device and improving its energy-saving effect.

[0020] The beneficial effects of this utility model are: This easily detachable solar ventilation skylight works by pushing the component to move the wedge block. The wedge block, with the help of the adapting inclined surface, pushes two moving plates to slide along the moving groove and move away from each other. At the same time, the two moving plates drive two limiting plates away from each other and store the limiting plates inside the moving groove. At this point, the limiting at the top of the glass body disappears. The glass body can then be removed and replaced through the placement groove, which improves the convenience of glass body replacement. Attached Figure Description

[0028] Please see Figures 1-6 As shown, this embodiment provides a solar ventilation skylight that is easy to disassemble, including: Ventilation frame 1, with window frame 6 hinged to the top of ventilation frame 1; Two placement slots 10 are respectively opened on both sides of the inner wall of the window frame 6. A glass body 11 is provided at the top of the two placement slots 10. A moving slot 12 is opened inside the window frame 6. Moving plates 13 are slidably connected to both sides of the inner side of the moving slot 12. Adaptive inclined surfaces 14 are opened at the adjacent ends of the two moving plates 13. A wedge block 18 is slidably connected between the two adaptive inclined surfaces 14. Limiting plates 17 are fixedly connected to the side of the two moving plates 13 that are close to each other. The two limiting plates 17 pass through the window frame 6 and are set on the top sides of the glass body 11. A push component is located on one side of the window frame 6 and is used to move the wedge block 18. The reset assembly is located on both sides inside the moving slot 12 and is used to drive the two moving plates 13 to reset.

[0029] In this process, by pushing the component to move the wedge block 18, the wedge block 18 pushes the two moving plates 13 to slide along the moving groove 12 and move away from each other with the help of the adapting inclined surface 14. At the same time, the two moving plates 13 drive the two limiting plates 17 to move away from each other and store the limiting plates 17 inside the moving groove 12. At this point, the limiting at the top of the glass body 11 disappears, and the glass body 11 can be taken out through the placement groove 10, which improves the convenience of replacing the glass body 11 of the device.

[0030] After the glass body 11 is replaced, the wedge block 18 is moved by pushing the component. The wedge block 18 releases the pressure on the adapting inclined surface 14. At this time, the reset component pushes the two moving plates 13 to slide closer along the moving groove 12.

Example 2

[0031] This embodiment provides a solar ventilation skylight that is easy to disassemble. In addition to the technical solutions of the above embodiments, it also has the following technical features, and the driving component includes: The housing 25 is fixedly connected to one side of the window frame 6. Inside the housing 25, a telescopic block 20 and a push block 23 are slidably connected. A sliding inclined surface 22 is provided on one side of the telescopic block 20, and a sliding inclined surface 26 is provided on one side of the push block 23. The sliding inclined surface 22 and the sliding inclined surface 26 are slidably engaged. A telescopic rod 24 is fixedly connected to the inner wall of the housing 25. One end of the telescopic rod 24 is fixedly connected to one side of the push block 23. A connecting rod 19 is fixedly connected to one side of the telescopic block 20. One end of the connecting rod 19 passes through the window frame 6 and is fixed to one side of the wedge block 18. A spring 21 is sleeved on the outer wall of the connecting rod 19. One end of the spring 21 is fixedly connected to one side of the telescopic block 20, and the other end of the spring 21 is fixedly connected to the window frame 6.

[0032] Specifically, by activating the telescopic rod 24, the push block 23 is moved. The push block 23 pushes the telescopic block 20 to move by means of the sliding engagement between the sliding inclined surface 1 22 and the sliding inclined surface 26. While the telescopic block 20 compresses the spring 21, the telescopic block 20 sequentially drives the connecting rod 19 and the wedge block 18 to move. The wedge block 18 completes the squeezing and moving of the moving plate 13 by means of the adapting inclined surface 14.

[0033] After the glass body 11 is installed, the telescopic rod 24 is activated to retract the push block 23. At this time, the compressed spring 21 pushes the telescopic block 20 back to its position. The telescopic block 20 then drives the connecting rod 19 and the wedge block 18 back to their positions and releases the pressure on the moving plate 13. Example 3

Several spring telescopic rods 15 are fixedly connected to the inner sides of the moving groove 12, and the multiple spring telescopic rods 15 are located inside the multiple springs 16.

[0035] When the wedge block 18 pushes the two moving plates 13 to slide along the moving groove 12 and move away from each other with the help of the adapting inclined surface 14, the two moving plates 13 will compress a number of spring telescopic rods 15 and spring 16. When the wedge block 18 returns to its position and releases the pressure on the moving plates 13, the elastic force of the compressed spring telescopic rods 15 and spring 16 will be released and push the two moving plates 13 to drive the two limiting plates 17 to slide out of the moving groove 12.

[0041] Specifically, the L-shaped movable plate 13 and the U-shaped movable groove 12 are adapted to each other, thereby enabling the movable plate 13 to slide inside the movable groove 12; the right-angled triangular inclined surfaces of the telescopic block 20 and the pushing block 23 are in contact and sliding fit, thereby enabling mutual driving between the telescopic block 20 and the pushing block 23; and the wedge block 18 is squeezed and pushed by the movable plate 13 by the sliding fit between the trapezoidal inclined surface of the wedge block 18 and the adapting inclined surface 14. Example 7

[0042] This embodiment provides a solar ventilation skylight that is easy to disassemble. In addition to the technical solution of the above embodiment, it also has the following technical features: the photovoltaic panel 4 is electrically connected to the battery 5, and the battery 5 is electrically connected to the telescopic rod 9 and the telescopic rod 24 in sequence.

[0043] In this system, solar energy is converted into electrical energy by photovoltaic panel 4 and stored in battery 5. Battery 5 then supplies power to telescopic rod 9 and telescopic rod 24, thereby enabling the normal operation of the device and improving its energy-saving effect.

[0044] Working principle: The second telescopic rod 24 is activated, which drives the push block 23 to move. The push block 23 pushes the telescopic block 20 to move by means of the sliding engagement between the first sliding inclined surface 22 and the second sliding inclined surface 26. While the telescopic block 20 compresses the second spring 21, it also drives the connecting rod 19 and the wedge block 18 to move in sequence. The wedge block 18 uses the matching inclined surface 14 to squeeze and move the moving plate 13. The two moving plates 13 slide along the moving groove 12 and move away from each other. At this time, the two moving plates 13 compress several spring telescopic rods 15 and the first spring 16. At the same time, the two moving plates 13 drive the two limiting plates 17 to move away from each other and store the limiting plates 17 inside the moving groove 12. At this point, the limiting at the top of the glass body 11 disappears. The glass body 11 can then be taken out through the placement groove 10, which improves the convenience of replacing the glass body 11 of the device.

[0045] After the new glass body 11 is placed in the placement slot 10, the telescopic rod 24 is activated to retract the pushing block 23. At this time, the compressed spring 21 pushes the telescopic block 20 back to its original position. The telescopic block 20 then drives the connecting rod 19 and the wedge block 18 back to their original positions and releases the pressure on the moving plate 13. At this time, the compressed spring telescopic rod 15 and the spring 16 push the two moving plates 13 to slide closer together along the moving slot 12. At the same time, the two moving plates 13 drive the two limiting plates 17 to slide out of the moving slot 12 and move to the top sides of the glass body 11, thus completing the limiting installation operation of the glass body 11.

[0046] In this invention, the electrical components are controlled by an external controller that is paired with them. The control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field and is used without modification. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
