Description

technical field [0001] The invention relates to a ventilation window, in particular to a ventilation window for an anti-theft door used for renovation of an old anti-theft door to improve indoor ventilation conditions. Background technique [0002] There are no ventilation windows on the anti-theft doors produced in the early stage. When such anti-theft doors are used in houses with non-permeable units, the ventilation effect of the houses is not good. In order to overcome this drawback, our company has developed anti-theft door ventilation windows for refitting old anti-theft doors, such as the disclosed products of CN 203742401 U and CN 204457284 U. But the ventilation doors of these two kinds of anti-theft door ventilation windows are all installed on the window frame by ordinary hinges, and the ventilation doors adopt the same horizontal rotation mode switch as ordinary doors. Therefore, when the anti-theft door ventilation windows of this structure When the ventilation...
