Situation.
In figure, building enclosure 1, vent 2, air port BAIYE 3, framework 4, side plate 5 overturn kickboard 6, sealing strip 7, rotating shaft 8.
Specific embodiment
As shown in Fig. 2 reverse-filling ventilation shaft of the present invention, including building enclosure 1 and the ventilation for being fixed on 1 side of building enclosure
Mouth 2, is also fixed on the framework 4 on the outside of building enclosure 1 including sealing, and external diameter of 4 internal diameter of the framework slightly larger than vent 2 is gone back
Including the bottom upset kickboard 6 hinged with the framework 4, the upset kickboard 6 can be logical to close with 4 peripheral sealing contact of framework
Air port 2.
When the opening of kickboard 6 is overturn, ventilation shaft is normally divulged information.When kickboard 6 is overturn with 4 peripheral sealing contact of framework, envelope
Vent 2 is closed, prevents outdoor hydrops from pouring in down a chimney into hypogee from vent.
To ensure sealing effectiveness and reducing construction and installation required precision, 6 periphery of upset kickboard is provided with can be close with framework 4
The sealing strip 7 that sealing-in is touched.
Above-mentioned closing mode, can be not only used for circular air port, it can also be used to conventional rectangle air port.Below for rectangle air port
Work optimizes.
The vent 2 is rectangle, and the framework 4 is also rectangle.
Preferably, the upset kickboard 6 is multiple, and the plurality of upset kickboard 6 is arranged in order from the bottom to top along framework 4,
When the plurality of upset kickboard 6 is with 4 peripheral sealing contact of framework, adjacent upset kickboard 6 is also in sealing contact.
Described each upset 6 bottom of kickboard is connected with 4 left and right pillar of framework by hinge near two ends.
For attractive in appearance and security consideration, the framework 4 is each side fixedly connected with side plate 5, and described each upset is floating
6 bottom two ends of plate are flexibly connected with side plate 5 by rotating shaft 8.
Height of the width of the side plate 5 slightly larger than upset kickboard 6.
So, just it is hidden in left side plate during open mode when overturning kickboard 6 and being flat, it is both attractive in appearance, also will not be by pedestrian
Hit by mistake.
For it is above-mentioned it is multiple upset kickboards 6 rectangle air port reverse-filling ventilation shafts, the such as Fig. 3 of course of work during its waterproof,
4th, shown in 5,6.As a example by diagram overturns kickboard by three.But it is not limited to three.
When outdoor hydrops are highly less than 2 lower edge of vent, kickboard 6 need not be overturn and worked, as shown in Figure 3.Now divulge information
Mouth is normal to divulge information.
When outdoor hydrops are higher than highly 2 lower edge of vent, first piece of upset kickboard 6 is started working, and water is kept off outside,
