They have the function of preventing the spread of fire and smoke, and can prevent the spread of fire within a certain period of time to ensure the evacuation of personnel. Most of the existing fire-resistant windows are made of aluminum alloy, but the fire-resistant windows made of aluminum alloy are too fixed. If they need to be repaired, they need to be dismantled, which is a cumbersome process and cannot be automatically closed.

[0003] Patent No. CN202122923732.6 discloses a self-locking fire-resistant window, which is provided with a window frame and a fire-resistant window body installed inside the window frame.
