[0002] Currently, buildings are typically equipped with fire-resistant windows and smoke extraction windows. These devices provide additional safety during a fire, preventing the spread of fire and smoke.

[0003] Smoke exhaust windows are primarily used in evacuation corridors and fire-risk areas during a fire, venting smoke through operable exterior windows or automatic smoke exhaust windows. The design of smoke exhaust windows requires them to open promptly and effectively during a fire to ensure unobstructed evacuation routes and the safety of personnel. During a fire, they open to allow natural convection between the indoor and outdoor spaces. However, in a fire, time is extremely limited, and people often cannot spare the time to open windows, especially in large buildings such as exhibition halls or factories where windows are often located in inaccessible areas, let alone openable. Therefore, designing an automatic opening and closing window sliding mechanism is essential. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a pneumatic window push-pull device that can open windows automatically and effectively exhaust smoke.

The cylinder push-pull mechanism 3 includes a cylinder 31 rotatably mounted on the window frame 1, a push-pull rod 32, and a push-pull plate 33 mounted on the opening end of the window 2. The push-pull rod 32 is linked with the cylinder 31, and the push-pull plate 33 is linked with the push-pull rod 32. The push-pull plate 33 moves with the push-pull rod 32 and drives the window 2 to perform opening or closing actions. It also includes an adjustment assembly 4, which is disposed between the push-pull rod 32 and the push-pull plate 33. The adjustment assembly 4 includes an adjustment plate 41 rotatably mounted on the push-pull plate 33 and two adjustment nuts 42. The push-pull rod 32 has a screw portion 321 at the end facing the window 2. The adjustment plate 41 has an adjustment hole 411 through which the screw portion 321 passes. The two adjustment nuts 42 are respectively mounted on the screw portion 321 and are respectively clamped on both sides of the adjustment plate 41. The position of the adjusting plate can be adjusted by rotating the two adjusting nuts, thereby adjusting the window opening angle. By adjusting to a larger window opening angle, a larger ventilation area can be effectively increased, which helps to improve smoke extraction efficiency.
