Description
Technical Field
[0001] This utility model relates to the field of smoke exhaust equipment technology, and in particular to a natural smoke exhaust window for a basement sloping roof with dust prevention function. Background Technology
[0002] In existing buildings, many structures include basements to improve land utilization. Basements have a wide range of uses, such as parking lots and storage rooms. However, due to their low elevation and humid climate, basements require frequent ventilation; otherwise, items inside are prone to mold or damage. Common basement smoke extraction methods include the following two: The first method involves excavating smoke vents in the sloping roof of the basement, installing chimneys above the vents, and mechanically expelling smoke and dust from the chimneys. The drawback of this method is its high cost and maintenance. The second method is natural smoke extraction. The drawback of this method is that the smoke vents need to be kept open continuously, allowing a large amount of fallen leaves or debris to fall into the basement. Furthermore, during heavy rainfall, the basement may leak due to insufficient sealing of the smoke vents. A new type of smoke extraction structure is needed. Summary of the Invention
[0003] To address the aforementioned issues, this utility model provides a dustproof natural smoke exhaust window for a sloping roof of a basement, which improves smoke exhaust efficiency, prevents debris from entering the basement through the smoke exhaust vent, and enhances the sealing performance of the smoke exhaust vent.
[0004] The technical solution of this utility model is as follows: A natural smoke exhaust window for a basement sloping roof with dustproof function, comprising a fixed frame fixedly connected to the basement sloping roof, a first window frame hinged to the fixed frame, a second window frame hinged to the fixed frame, a first connecting frame hinged to the first window frame, and a second connecting frame hinged to the second window frame. The first connecting frame is hinged to the second connecting frame, and a hinge base is provided between the first and second connecting frames. Both the first and second connecting frames are provided with screens, and both the first and second window frames are provided with transparent glass. The hinge base is provided with a first limiting baffle and a second limiting baffle, respectively. When the first and second window frames rotate a certain angle, the first limiting baffle and the second limiting baffle are in a mutually abutting state with the first and second connecting frames, respectively, and at this time, the first and second connecting frames are on the same horizontal plane. Both the first and second window frames are provided with fixing grooves, and the shape of the fixing grooves is adapted to the cross-sectional shape and size of the first and second connecting frames, respectively.
[0005] Using the above technical solution, when natural smoke exhaust is required, the user can open the first and second window frames towards the basement. After rotating the first and second window frames by a certain angle, the first and second connecting brackets are also in a horizontal state. At this time, the screens on the first and second connecting brackets block sand and debris, while not affecting the smoke exhaust efficiency and improving the air circulation efficiency of the basement. When it rains, the first and second window frames can be closed. Since the shape of the fixing groove is adapted to the cross-sectional shape and size of the first and second connecting brackets, the first and second connecting brackets can fill the fixing groove, ensuring the airtightness of the smoke exhaust and preventing rainwater from entering the basement.
[0006] A further feature of this invention is that the inner wall of the fixing groove is provided with a first sealing gasket, and the first connecting frame and the second connecting frame are both provided with a second sealing gasket. The second sealing gasket is provided at the connection end between the first connecting frame and the first window frame and the connection end between the second connecting frame and the second window frame.
[0007] By adopting the above technical solution, since the inner wall of the fixing groove is provided with a first sealing gasket and the second sealing gasket is provided at the connection end between the first connecting frame and the first window frame and the connection end between the second connecting frame and the second window frame, the overall sealing performance of the smoke exhaust port can be greatly improved when the first window frame and the second window frame are in the closed state, thus preventing rainwater from entering the basement.
[0008] A further feature of this invention is that the first limiting baffle and the second limiting baffle are respectively provided with a first magnetic element and a second magnetic element, and the first magnetic element and the second magnetic element can attract each other with the first connecting frame and the second connecting frame, respectively.
[0009] By adopting the above technical solution, since the first limiting baffle and the second limiting baffle are respectively provided with the first magnetic element and the second magnetic element, when the first window frame and the second window frame are in the open state, the connection stability between the first limiting baffle and the second limiting baffle can be improved, thereby improving the overall stability of the connection structure between the first connecting frame and the second connecting frame, and preventing gaps between the two from causing debris to enter the basement.
[0010] A further feature of this invention is that both the first connecting frame and the second connecting frame are provided with a third sealing gasket, which is located at the connection end with the hinge base.
[0011] By adopting the above technical solution, since both the first connecting frame and the second connecting frame are equipped with a third sealing gasket, the overall sealing performance of the smoke vent can be further improved when the first window frame and the second window frame are in the open state, thus preventing debris from entering the basement.

Detailed Implementation
[0015] like Figure 1-2 As shown, a basement sloping roof natural smoke exhaust window with dustproof function includes a fixed frame 1 fixedly connected to the basement sloping roof, a first window frame 2 hinged to the fixed frame 1, a second window frame 3 hinged to the fixed frame 1, a first connecting frame 4 hinged to the first window frame 2, and a second connecting frame 5 hinged to the second window frame 3. The first connecting frame 4 is hinged to the second connecting frame 5. A hinge base 6 is provided between the first connecting frame 4 and the second connecting frame 5. Both the first connecting frame 4 and the second connecting frame 5 are provided with a screen 7. Each frame 3 is provided with transparent glass 8. The hinge base 6 is provided with a first limiting baffle 9 and a second limiting baffle 10. When the first window frame 2 and the second window frame 3 rotate at a certain angle, the first limiting baffle 9 and the second limiting baffle 10 are in a state of mutual contact with the first connecting frame 4 and the second connecting frame 5 respectively. At this time, the first connecting frame 4 and the second connecting frame 5 are on the same horizontal plane. The first window frame 2 and the second window frame 3 are provided with fixing grooves 11. The shape of the fixing grooves 11 is adapted to the cross-sectional shape and size of the first connecting frame 4 and the second connecting frame 5 respectively.
[0016] When natural smoke exhaust is needed, the user can open the first window frame 2 and the second window frame 3 towards the basement. After rotating the first window frame 2 and the second window frame 3 by a certain angle, the first connecting bracket 4 and the second connecting bracket 5 are also in a horizontal state. At this time, the screen 7 on the first connecting bracket 4 and the second connecting bracket 5 blocks sand and debris, and at the same time, it does not affect the smoke exhaust efficiency of the smoke exhaust vent, improving the air circulation efficiency of the basement. When it rains, the first window frame 2 and the second window frame 3 are closed. Since the shape of the fixing groove 11 is adapted to the cross-sectional shape and size of the first connecting bracket 4 and the second connecting bracket 5, the first connecting bracket 4 and the second connecting bracket 5 can fill the fixing groove 11, ensuring the airtightness of the smoke exhaust vent and preventing rainwater from entering the basement.
[0017] The inner wall of the fixing groove 11 is provided with a first sealing gasket 12, and the first connecting frame 4 and the second connecting frame 5 are both provided with a second sealing gasket 13. The second sealing gasket 13 is provided at the connection end between the first connecting frame 4 and the first window frame 2 and the connection end between the second connecting frame 5 and the second window frame 3.
[0018] Since the inner wall of the fixing groove 11 is provided with a first sealing gasket 12, and the second sealing gasket 13 is provided at the connection end between the first connecting frame 4 and the first window frame 2 and the connection end between the second connecting frame 5 and the second window frame 3, the overall sealing performance of the smoke vent can be greatly improved when the first window frame 2 and the second window frame 3 are in the closed state, thus preventing rainwater from entering the basement.
[0019] The first limiting baffle 9 and the second limiting baffle 10 are respectively provided with a first magnetic element 14 and a second magnetic element 15, and the first magnetic element 14 and the second magnetic element 15 can attract each other with the first connecting frame 4 and the second connecting frame 5 respectively.
[0020] Since the first limiting baffle 9 and the second limiting baffle 10 are respectively provided with the first magnetic element 14 and the second magnetic element 15, when the first window frame 2 and the second window frame 3 are in the open state, the connection stability between the first limiting baffle 9 and the second limiting baffle 10 can be improved, thereby improving the overall stability of the connection structure between the first connecting frame 4 and the second connecting frame 5, and preventing gaps between them from causing debris to enter the basement.
[0021] The first connecting frame 4 and the second connecting frame 5 are each provided with a third sealing gasket 16, which is located at the connection end with the hinge base 6.
[0022] Since the first connecting frame 4 and the second connecting frame 5 are both equipped with a third sealing gasket 16, the overall sealing performance of the smoke vent can be further improved when the first window frame 2 and the second window frame 3 are in the open state, thus preventing debris from entering the basement.
