Lamellar structure for multifunctional movable louver window

The utility model relates to a kind of multifunctional movable blade of louver window structure, it is characterized by and one have "

" blade construction of shape; the shutter formed of blade construction has multiple functions such as rainproof, dustproof, fire prevention, explosion-proof, anti-platform, sun-proof, antitheft, sound insulation, ventilation and daylighting thus; so this product must cause customer's hobby; also more improve the progressive of this series products industry; and the flexibility height of this structure; make applicable to fixed, hand and electrodynamic type shutter, the manufacturing of this structure simultaneously is simple and easy fast, therefore can keep low-cost but multi-functional shutter.

Traditional louver is the structure of dullness, and using upward in reality, regular meeting has following problem to take place:

(1) because the plane appearance of blade is rather dull, except that the ventilation effect, other is as rainproof, dustproof, windproof ... etc. the equal extreme difference of effect.

(2) aspect its sound construction, because of the coupling part of its thin construction profile and framework engages for linear, the abutment is more not attractive in appearance, insecure so traditional blade of louver window regular meeting has, the destruction of material and time-consuming puzzlement generation.

By the common problem of above-mentioned institute, traditional shutter aesthetic property often is better than the functional and structural fastness that it uses, and has reduced the practical effect of shutter.

Based on above-mentioned problem place, the purpose of this utility model provides a kind of multifunctional movable blade of louver window, except that keeping traditional louvre ventilation, daylighting, sun-proof effect, increase dustproof and rainproof function again, simultaneously, when applying on the movable shutter, by adjusting blade angle, make that when closure state tool is windproof, explosion-proof, the effect of fire prevention and sound insulation, in addition, on structure is fixing, adopt groove shape structure, tool large tracts of land combination when it is connected with window frame, and have more fastness.

For achieving the above object, the utility model provides a kind of multi-functional shutter blade construction, it is characterized by a tool "

" blade construction of shape; this shape is the center with its central oval hollow strip axle center; upper and lower respectively have a reverse open slot, and the ramp portion of this groove shape structure steering current flow direction has the miter angle gradient approximately, but and water conservancy diversion and the arcuation trench bottom that blocks dust is arranged.

Fig. 7 is the preferable enforcement figure of one of the utility model.

Below execute example especially exemplified by one, and conjunction with figs. describes structure, function and the feature of the utility model in detail:

At first, seeing also shown in Figure 1ly, is to be a traditional structure sectional drawing, traditional as seen from the figure blade 1 be a kind of " " structure of shape, its inclined plane and window frame are the combination of miter angle, are a dipping type shutter.Yet the shutter of this structure composition is because its gas channel is a straight line, so in the direct inlet chamber of air-flow, thereby also directly dirt sand is held under the arm into indoor easily, and be splashed into indoor easily by rainwater, as shown in the figure if at the surface bottom of the blade raindrop that drip, blown by high wind then easily to follow to rise on this inclined-plane indoor up to splashing into, its dustproof and rainproof effect is not good.So rather inconvenience, blade with Fig. 2 compares again, even rainwater blows when making water droplet rise to its oval hollow strip axle center 21 if drop in 23 high wind of its surface bottom, stopped, therefore water droplet just can't enter into indoor, this is one of the utility model function, but if rainwater drops in end on the oval hollow strip axle center 21.Similarly if high wind makes water droplet rise to arcuation bottom land part 221 promptly can be blocked and to drop to ramp 222, also make rainwater can't inlet chamber in, this is two of the utility model function, so the utility model has reached rainproof effect really.In addition, shown in its cross-section structure, traditional blade is the appearance of dull plane, and its engage with window frame partly few, so its bond strength is little, very not firm down to the shutter overall structure.

Continue to see also Fig. 2 and Fig. 3, be for the section of structure of the utility model and and three-dimensional structure diagram, shown in figure, the structure of the utility model is the

groove shape structure

22,23 of a pair of upper and lower symmetrical reverse opening, its outer arcuation trench bottom 221,231, be to form the both sides of air flow channel, also have simultaneously and block dust and be blown into indoor effect; 222,232 of the inner ramp portion of structure are the predominant wind guide plate of structure, and the outer air-flow of its induction room blows from lower to upper to strengthen the circulation of room air.And if this blade construction is applied on the fixed shutter, then the groove shape structure of the utility model can strengthen the contact area with window frame, makes overall structure more firm; Oval hollow strip axle center 21 axis of rotation of structure for this reason of diagram central authorities also is and the fixing part of framework.

Continue to see also Fig. 4, it is section allocation plan for the utility model, shown in figure, the oval hollow strip axle center 21 of two blade constructions places on the perpendicular bisector, and the allocation position that end slot shape structure 22 is as shown on end slot shape structure 23 and the lower leaflet under the blade of top, the upper and lower lobes chip architecture is formed the bending channel of centre thus, then can form the gas channel of shutter, the tortuosity of this gas channel can prevent that rainwater is indoor because of high wind is splashed into, and it is indoor also can to prevent that dirt sand directly is blown into simultaneously.

Continue to see also Fig. 5, be to be the section allocation plan of the utility model when closed, shown in figure, when the utility model is arranged at venetian blinds, when blade is rotating shaft with oval hollow strip axle center 21, the window blade rotates counterclockwise about 20 when spending simultaneously, then end slot shape structure can be linear with end slot shape structure on the lower leaflet and contacts under the blade of top, form the shutter closure state, under this state, the utlity model has the function of typhoon protection, fire prevention, explosion-proof, antitheft and sound insulation, reach required obturation effect effectively.

Continuing to see also Fig. 6, is that the section during for the utility model standard-sized sheet rotates schematic diagram, shown in figure, when blade is arranged at venetian blinds, blade is rotating shaft with oval hollow strip axle center 21, when each blade all clockwise rotates about an angle of 90 degrees, forms the shutter full-gear.This moment, the space between each blade increased, and was the level of state approximately, can increase indoor-outdoor air to flow and strengthen indoor daylighting effect.From being closed to full-gear, the activity point of view of blade is about 110 degree angles, can use various drive shafts to reach the effect that makes blade rotation.

Continuing to see also Fig. 7, is for one of the utility model preferred embodiment figure, and shown in figure, the utility model can be fixed in the both sides in the oval hollow strip axle center 21 of this blade on the window frame 3 or be fixed on the movable rotation-shaft.Be applicable on the fixed or movable shutter, have much flexibility and practicality.
