The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 2, the utility model provides a kind of automatic windproof sudden and violent shutter, comprise window frame 2 and be arranged in successively the multi-disc louvre blade 1 in window frame 2, the two ends of louvre blade 1 are rotated and are arranged on two relative inner faces of window frame 2, are also provided with certain the first alignment pin 31 and the second alignment pin 32 of rotational angle that limits respectively every a slice louvre blade 1 on two relative inner faces of window frame 2.
The sudden and violent shutter of automatic windproof that the utility model provides, storm comes interim, under wind action, louvre blade automatic rotating, the draught area of change shutter, prevents the unnecessary impact that storm causes indoor environment.
Concrete, as shown in Figure 2, the sudden and violent shutter of automatic windproof that the utility model provides, its louvre blade 1 comprises cross blade 12 and is vertically set on the portion windward 11 of cross blade 12 rear ends, portion 11 is near indoor windward, and cross blade 12 is fixed on window frame by the turning cylinder 4 being fixed on window frame 2, and the moving axis 4 that rotates rotates, the first alignment pin 31 is positioned at the below of cross blade 12 and is positioned at cross blade 12 belows and near portion 11 windward away from portion's 11, the second alignment pins 32 windward.
In the utility model, on louvre blade 1, the part that portion 11 is positioned at cross blade 12 tops is windward called the first half of portion windward, and the part that portion 11 is positioned at cross blade 12 belows is windward called the Lower Half of portion windward; Cross blade 12 is called the rear end of cross blade near one end of portion 11 windward, cross blade 12 is called the front end of cross blade away from one end of portion 11 windward.
Concrete, as shown in Figure 3, when outdoor wind speed hour, wind 5 acts on the gravity torque that the moment of portion 11 is windward less than louvre blade 1 itself, and the cross blade 12 of louvre blade 1 moving axis 4 that rotates clockwise rotates, until the front end of cross blade 12 is resisted against on the first alignment pin 31, now, the Lower Half of portion 11 is away from the first half of portion windward of its below louvre blade windward, has windward certain gap between adjacent louvre blade between portion that is:, and outdoor wind enters indoor by this gap.
As shown in Figure 4, when outdoor wind speed is larger, wind acts on the moment of portion 11 windward and is greater than the gravity torque of louvre blade 1 own, the cross blade 12 of louvre blade 1 drives windward portion 11 moving axis 4 that rotates to rotate counterclockwise, the Lower Half of portion 11 is resisted against on the second alignment pin 32 windward, and the first half laminating of the portion windward 11 of the louvre blade of the Lower Half of portion 11 and its below windward, that is: the portion windward between adjacent louvre blade is bonded to each other, and shutter is closed.
The sudden and violent shutter of automatic windproof that the utility model provides, without Auxiliary Power Unit, has realized the automatic adjusting of louvre ventilation area with outdoor wind speed size.When outdoor wind speed hour, under the effect of louvre blade own wt, shutter is opened automatically, realizes the free exchange of indoor-outdoor air; Next interim compared with tempest when outdoor wind speed power, under the effect of blast, shutter is closed automatically, indoorly avoids the unnecessary impact that storm causes.
For making the second alignment pin 32 of each louvre blade be positioned at vertical sash 2 wherein on a straight line of a side, and when wind speed is larger, shutter can be completely closed, preferably, the Lower Half of portion and the first half certain distance that staggers windward, the stagger distance of the first half of its Lower Half is the thickness of portion windward, the opposite direction of the direction that staggers and cross blade 12.
Gravitational moment for adjusting louver sheet, make the shutter can be according to the size of outdoor wind speed, regulate gap between adjacent louvre blade to optimum position, preferably, the top of portion and the front end of cross blade arrange kink windward, and portion's bending part 111 is perpendicular to portion is towards outdoor windward windward, and cross blade bending part 121 is towards the below of cross blade.
Best, cross blade bending part 121 is hollow frame structure.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
