Description

Technical Field

[0001] This application relates to the technical field of curtain wall casement windows, and more specifically, to an aluminum alloy curtain wall window structure. Background Art

[0002] A curtain wall window is a casement window fixed on a curtain wall. It is one of the peripheral protection structures of a building and also a decoration of the building facade. It is widely used in high-rise buildings. The existing curtain wall windows are mainly composed of a skeleton, individual window frames fixed on the skeleton, and windows installed in each window frame.

[0003] Some existing curtain wall windows are mainly pushed open manually. During the opening process, the user may stretch the upper body out of the window. Since the height of the casement window is relatively low, during the opening process, the user may lose balance and fall out of the window, which is highly dangerous and not conducive to the safe use of the user. Moreover, the opening angle of the curtain wall window is limited when it is opened, which may weaken the air ventilation effect in the room, resulting in a poor air quality in the indoor space and unable to provide a good working environment for the user. Therefore, an aluminum alloy curtain wall window structure is proposed. Summary of the Invention

[0052] Then rotate the movable rod 23 clockwise, driving the rotation of the rotating outer shell 22 and the rotating table 21, and then driving the circumferential rotation of the first fixing rod 27 and the second fixing rod 30 on both sides. During the rotation of the first fixing rod 27, it will apply a pulling force to the first connecting rod 5 through the first fixing shaft 28, and then rotate under the action of the first rotating shaft 7, while applying a pulling force to the first rotating rod 6 and rotating under the action of the third fixing shaft 8, and then the other end applies an external force to one of the windows 4 through the first cylindrical shaft 10 and the first fixing seat 11, driving it to rotate and open.

[0053] During the rotation of the second fixed rod 30, a tensile force will be applied to the second connecting rod 12 through the second fixed shaft 29, and then it will rotate under the action of the second rotating shaft 14. At the same time, a tensile force will be applied to the third rotating rod 13, and it will rotate under the action of the fourth fixed shaft 15. Then, the other end will apply an external force to another window 4 through the second cylindrical shaft 18 and the second fixed seat 19 to drive it to rotate and open. After the two windows 4 are fully opened, stop rotating the movable rod 23. Then, press down the movable rod 23 to store it inside the rotating housing 22.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby.
