Window closing device for aluminum alloy fire-resistant window
The invention discloses a window closing device for an aluminum alloy fire-resistant window. According to the window closing device, a limiting block and a folding block are punched on a small sliding plate at the same time through the integrated punching technology, a square hole is reserved, a blasting bead fixing block is placed in the square hole and a square hole formed in a sliding groove, when a fire disaster occurs and a certain temperature is reached, an arranged temperature sensing glass ball explodes, When the window is opened, the blast bead fixing block falls from the two square holes, a tension spring pulls the small sliding plate to drive s window sash to be closed, indoor air circulation is rapidly reduced, and the situation that the fire behavior is increased due to flowing of indoor air and air outside the window is prevented.
本发明公开了一种铝合金耐火窗闭窗器，采用一体冲压工艺将小滑板同时冲压有限位块和折块，并留有方形孔，与滑槽上设置的方形孔一起来放置爆珠固定块，当发生火灾达到一定温度时，设置的感温玻璃球爆炸，爆珠固定块从两个方形孔中掉落，拉簧拉动小滑板来带动窗扇关闭，使其快速达到减少室内空气的流通，防止因室内与窗外空气发生流动而使火势增大的情况发生。
