After the ventilation door of the anti-theft door ventilation window is opened, the ventilation door cannot protrude towards a room, and cannot occupy the indoor space, the influence of the ventilation door on the indoor space is small, normal activity of indoor persons cannot be disturbed, and safety ofthe indoor persons cannot be endangered.

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...

Problems solved by technology

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 door is opened inward, the ventilation door will protrude from the anti-theft door panel, which not only occupies the indoor space, but also the protruding corners of the ventilation door are easy to scratch with the indoor personnel, causing injury to personnel, and there is a great potential safety hazard, which makes personnel limited movement indoors
