[0002] With the development of society and the advancement of technology, the construction industry has also ushered in rapid development in recent years. High-rise and super-high-rise buildings have sprung up everywhere, and glass curtain walls have also been widely used. Buildings need ventilation. Currently, most existing curtain wall ventilation systems use windows on the facade, such as top-hung windows and casement windows.

[0003] However, there are the following problems in setting up opening windows on glass curtain walls:

[0004] (1) Opening the window will destroy the facade effect of the curtain wall and affect the aesthetics of the glass curtain wall;

[0030] The upper and lower walls of the ventilation cavity are respectively vertically fixed with an upper blocking plate 4 and a lower blocking plate 5, the front and rear ends of the upper blocking plate 4 and the lower blocking plate 5 are respectively in contact with the front and rear walls of the ventilation cavity, and the front and rear walls of the ventilation cavity are horizontally fixed with a rotating shaft 6; the closing plate 2 is located between the upper blocking plate 4 and the lower blocking plate 5, the front and rear ends of the closing plate 2 are respectively in contact with the front and rear walls of the ventilation cavity, a rotating hole matched with the rotating shaft 6 is opened in the middle of the closing plate 2, and the closing plate 2 is rotatably arranged in the ventilation cavity through the rotating shaft 6, the matching of the rotating shaft 6 and the rotating hole has a certain degree of tightness, and the cavity of the closing plate and the ventilation cavity is There is also a certain friction between the walls, which makes the rotation feel blocked, aiming to ensure that the closing plate 2 can stop at the current angle and provide a certain self-locking property; one end of the switch handle 3 is fixedly connected to the middle of the closing plate 2, and the other end extends into the room through the switch hole, and the switch handle 3 is moved up and down to drive the closing plate 2 to rotate; when the switch handle 3 is closed, the upper and lower ends of the closing plate 2 are respectively fitted with the upper blocking plate 4 and the lower blocking plate 5 to block the ventilation cavity; when the switch handle 3 is opened, the upper and lower ends of the closing plate 2 are respectively away from the upper blocking plate 4 and the lower blocking plate 5 to make the ventilation cavity unobstructed.

[0031] Furthermore, the ventilation frame 1 includes an outdoor panel 101, a ring side panel 102 and an inner buckle cover 103. The ring side panel 102 is fixedly installed between the upper and lower beams 7 of the curtain wall. The upper baffle plate 4 and the lower baffle plate 5 are an integrated structure with the ring side panel 102; the outdoor panel 101 is fixedly installed between the glass fixing kits 8 of the upper and lower curtain walls. Due to the limited thickness of the outdoor panel 101, the upper and lower ends of the outdoor panel 101 are bent into a U-shaped structure. The width of both sides of the U-shaped structure is the same as the thickness of the glass panel 9. The glass fixing kit 8 includes a bottom bracket, a PVC thermal break, a pressure plate, and a cover plate. Both sides of the U-shaped structure are installed in the glass fixing kit Between the base and the pressing plate in 8, a glass plate 9 is installed on the other side of the glass fixing kit 8, which is pressed and fixed between the base and the pressing plate together with the glass plate 9. The ends of the upper and lower ends of the outdoor plate 101 are also fixedly connected to the outdoor side of the ring side plate 102 so that the outdoor plate 101 is stably fixed; a snap structure is provided at one end of the ring side plate 102 located on the indoor side, so that the inner snap cover 103 is snap-fitted and connected to the indoor side of the ring side plate 102, and the inner snap cover 103 is detachable to facilitate the assembly and cleaning of the system; the ventilation holes 10 are arranged on the outdoor plate 101 and the inner snap cover 103, and the switch hole is arranged on the inner snap cover 103.

When the switch handle 3 is closed, the switch handle 3 is located at the bottom of the switch hole; when the switch handle 3 is opened, the switch handle 3 is located at the top of the switch hole. After long-term use, if the cooperation between the rotating hole and the rotating shaft 6 becomes loose, the switch handle 3 will slide downward due to gravity, causing the switch state to change. Through the above design, when the switch handle 3 slides down, the ventilation frame 1 can gradually enter the closed state, thereby improving safety.

[0035] Furthermore, a sealing strip 13 is bonded to the outer end surface of the upper barrier plate 4 and the inner end surface of the upper end of the closing plate 2; a sealing strip 13 is bonded to the inner end surface of the lower barrier plate 5 and the outer end surface of the lower end of the closing plate 2, thereby better meeting the contact between the closing plate 2 and the upper and lower barrier plates and forming a better closing effect.
