The fireproof window is a fireproof partition with certain fire resistance, which can prevent the spread of fire and the diffusion of smoke, and can prevent the spread of fire for a certain period of time to ensure personnel evacuation. The fireproof window on the current market is mainly divided into active fireproofing and passive fireproofing. Active fireproofing refers to closing the window sash to achieve the purpose of fireproofing. Passive fireproofing refers to achieving the purpose of fireproofing through heat-resistant, burn-resistant materials and special structural features.

[0003] According to the invention patent with application number CN202110713662.3, the fireproof window device still has some shortcomings in actual use. For example, the gap between the internal pulley and the sliding groove of the window frame of the current movable heat-insulating fireproof window is large, and no limiting structure is provided. Therefore, the pulley is prone to side shift and deviation during sliding. Long-term use may cause the window to be directly stuck and poor sliding smoothness. In the event of an emergency, the operation flexibility is low, and the safety level needs to be improved.
