[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0023] Reference Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a novel ventilation and smoke exhaust skylight locking device, comprising a window shell 1, two first fixing plates 2 are installed on the left side of the window shell 1, a cylinder 3 is installed on the top of the first fixing plate 2, a second fixing plate 4 is rotatably connected to the surface of the cylinder 3, a cover plate 5 is fixedly connected to the right side of the second fixing plate 4, and a handle 6 is fixedly connected to the right side of the cover plate 5. The novel ventilation and smoke exhaust skylight locking device also includes a hollow block 7 installed on the right side of the cover plate 5, and a telescopic slot 8 is opened on the right side of the inner cavity of the window shell 1;

[0024] The limiting mechanism is installed inside the window shell 1 and is used in conjunction with the hollow block 7. The limiting mechanism is used to limit the position of the cover plate 5. Since the existing ventilation and smoke exhaust skylights are in strong winds or bad weather conditions, the skylights without locking devices cannot effectively resist the wind and are easily blown open by the wind. Therefore, the staff can use the limiting mechanism to quickly open and lock the skylights.

[0025] Reference Figure 3 and Figure 4 As shown, in this embodiment: the limiting mechanism includes a telescopic rod 9 installed on the right side of the inner cavity of the telescopic groove 8, a pressing block 10 is fixedly connected to the left side of the telescopic rod 9, and a pull rod 11 is fixedly connected to the bottom of the pressing block 10. A notch 12 is provided at the bottom of the telescopic groove 8. The staff can pull the pull rod 11 from the outside to drive the pressing block 10 to retract into the telescopic groove 8 opened on the right side of the inner cavity of the window shell 1, thereby releasing the limit on the hollow block 7, and then push the handle 6 upward to lift the cover 5.

[0026] Reference Figure 4 As shown, in this embodiment: the left side of the pressing block 10 is a semi-arc-shaped inclined surface. By setting the shape of the left side of the pressing block 10 to a semi-arc-shaped inclined surface, when the staff pulls the cover 5 downward, there is no need to pull the pull rod 11. The pressing block 10 will automatically bounce into the interior of the hollow block 7 due to the shape of the semi-arc-shaped inclined surface to fix the position of the cover 5.

[0027] Reference Figure 4 As shown, in this embodiment: the right side of the pressing block 10 is fixedly connected with a return spring 13, and the right side of the return spring 13 is fixedly connected to the right side of the inner cavity of the telescopic slot 8. When the pressing block 10 contracts toward the inside of the telescopic slot 8, the return spring 13 located on the right side of the pressing block 10 will contract inward to accumulate force. When the pressing block 10 is not under force, the return spring 13 will drive the pressing block 10 to rebound quickly to the left, making it more stable when the staff is fixed.

[0028] Reference Figure 5As shown, in this embodiment: the front end and the rear end of the inner cavity of the telescopic slot 8 are both provided with a limiting slot 14, and the front end and the rear end of the pressing block 10 are both fixedly connected to the limiting block 15. By providing the limiting slots 14 at the front end and the rear end of the inner cavity of the telescopic slot 8, and the front end and the rear end of the pressing block 10 are both fixedly connected to the limiting block 15, the pressing block 10 is more stable when moving inside the telescopic slot 8.

[0029] Reference Figure 2 As shown, in this embodiment: a bidirectional torsion spring 17 is installed inside the cylinder 3, one end of the bidirectional torsion spring 17 is fixedly connected to the left side of the cover plate 5, and the other end of the bidirectional torsion spring 17 is fixedly connected to the left side of the window shell 1. By installing the bidirectional torsion spring 17 on the left side of the cover plate 5 and the window shell 1, when the staff releases the limit on the skylight, the skylight will open quickly due to the force generated by the bidirectional torsion spring 17, making it faster for the staff to use it.

[0030] Reference Figure 4 As shown, in this embodiment: a sealing gasket 16 is installed on the top of the window shell 1. By installing the sealing gasket 16 on the top of the window shell 1, the skylight is sealed on all sides when in a closed state, so that the skylight will not leak when encountering rainy weather.

[0031] The working principle of this utility model: Since the existing ventilation and smoke exhaust skylights without locking devices cannot effectively resist the wind force under strong winds or bad weather conditions and are easily blown open by the wind, the staff can use the limit mechanism to quickly open and lock the skylight. The staff can drive the pressing block 10 to retract into the telescopic slot 8 opened on the right side of the inner cavity of the window shell 1 by pulling the pull rod 11 from the outside, releasing the limit on the hollow block 7, and then push the handle 6 upward to lift the cover plate 5. By setting the shape of the left side of the pressing block 10 to a semi-arc inclined surface, the staff does not need to pull the pull rod 11 when pulling the cover plate 5 downward. The pressing block 10 will automatically bounce into the inside of the hollow block 7 due to the shape of the semi-arc inclined surface to fix the position of the cover plate 5. When the pressing block 10 retracts into the inside of the telescopic slot 8, the right side of the pressing block 10 The return spring 13 will contract inward and accumulate force. When the pressing block 10 is not under force, the return spring 13 will drive the pressing block 10 to rebound quickly to the left, making it more stable when the staff is fixed. By providing limit grooves 14 at the front and rear ends of the inner cavity of the telescopic slot 8, and at the same time, the front and rear ends of the pressing block 10 are fixedly connected to the limit blocks 15, the pressing block 10 is more stable when moving inside the telescopic slot 8. By installing a two-way torsion spring 17 on the left side of the cover plate 5 and the window shell 1, when the staff releases the limit on the skylight, the skylight will be quickly opened due to the force generated by the two-way torsion spring 17, making it faster for the staff to use it. By installing a sealing gasket 16 on the top of the window shell 1, the skylight is sealed on all sides when it is in the closed state, so that the skylight will not leak when encountering rainy weather.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
