[0002] A curtain wall is an exterior wall enclosure of a building, which does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with a decorative effect commonly used in modern large-scale and high-rise buildings. Composed of a panel and a support structure system, the curtain wall is fixed to the exterior wall in two ways: fixed and rotatable. Since the rotatable curtain wall can facilitate ventilation, it is often used in daily life. When ventilation is needed, the curtain wall is pushed, and at this time, the bottom end of the curtain wall rotates along the edge of the exterior wall. When not in use, the curtain wall can be rotated in the opposite direction to seal the curtain wall with the exterior wall.

[0003] However, the existing curtain walls do not have a structure that can open the curtain wall by pulling a handle. During the opening process of the curtain wall, the user needs to use the strength of the arm to push the curtain wall open. During the process of pushing open the curtain wall, the user's arm is at a high altitude, and this process poses a certain degree of danger to the user. In case of improper handling, the user may even fall from a high place. Therefore, there is an urgent need for a curtain wall ventilation structure to solve the above problems.
