Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of safe evacuation equipment, and in particular relates to a pressure relief escape window suitable for pressurized buildings. Background Art
[0002] Existing escape windows are mainly used in public transportation such as high-speed railways and buses. They are used to allow people to quickly open or break the escape windows to escape when an accident occurs and people cannot evacuate through doors.
[0003] However, existing escape windows typically use fragile glass, making them difficult to use in pressurized buildings. Pressurized buildings are often used in high-altitude areas, where they effectively alleviate altitude sickness by increasing the pressure inside the building to the same level as at lower altitudes. Theoretically, the indoor-outdoor pressure differential in pressurized buildings can reach 50 kPa. At this pressure differential, the window glass is relatively strong, making conventional window-breaking methods difficult and time-consuming. Furthermore, due to the airtight nature of pressurized buildings, conventional mechanical escape window opening methods require significant force, making them difficult to open properly.
