Description

Technical Field

[0001] The utility model relates to the field of fire smoke exhaust windows, in particular to a hidden fire smoke exhaust window structure. Background Art

[0002] In recent years, with the gradual improvement of fire protection design requirements in building construction, fire smoke exhaust windows are often installed on the external windows of the building. When the fire smoke exhaust window is at the top of a multi-pane combination window, it is impossible to open and close the top fire smoke exhaust window normally by hand. Usually, a manual device is installed at the bottom to open and close the upper fire smoke exhaust window, that is, without the help of other tools, the opening and closing of the upper fire smoke exhaust window can be controlled by the manual device while standing on the ground.

[0003] The traditional manual device installation method is: install fixings on both sides of the smoke exhaust window, install a full-length horizontal bar between the fixings, and install a support in the middle of the horizontal bar to support the smoke exhaust window to open and close it. Although this simple method can achieve the normal opening and closing of the smoke exhaust window, when the manual device position of the fire smoke exhaust window installed in the building requires the installation of indoor curtains, the traditional fire smoke exhaust window manual device conflicts with the installation of curtains, and the appearance of the manual device is relatively abrupt and rough, affecting the overall visual effect of the interior decoration.
