Abstract

The utility model discloses a blind window, which comprises a frame, a plurality of outer blades, a plurality of inner blades and a driving mechanism, wherein the outer blades are horizontally arranged in the frame at intervals; two ends of each outer blade are connected with the frame through shafts; the inner blades are opposite to the outer blades; the driving mechanism is in transmission connection with the shafts, so the shafts rotate in forward and reverse directions; and along with the forward rotation or reverse rotation of the shafts, the outer blades and the inner blades are in an open or closed state. The blind window is characterized in that when the outer blades and the inner blades are in the open state, an acute angle is formed between each outer blade and each inner blade. The blind window is high in ventilation function.

Description

Shutter

Technical field

The utility model relates to a kind of forms, relates in particular to a kind of shutter.

Background technology

Shutter is mounted in the window periphery and can shelters from a kind of device of window.Shutter comprises: intra vane and outer leafs, the parallel lamination setting of a plurality of outer leafs, the main body of formation shutter; Leave distance between the permanent position of adjacent blades, the corresponding setting with outer leafs of intra vane also includes driving mechanism; Be in transmission connection with blade, and blade is rotated with positive and negative direction, along with the forward or reverse of blade; Make above-mentioned outer leafs and intra vane be in the state of opening or closing, this kind shutter is simple, stable performance, and applicability is wider; But this kind shutter outer leafs and intra vane when open mode are in and are parallel to each other, and intra vane becomes the obstacle in the wind inlet chamber, thereby causes the air permeability of this kind shutter relatively poor.

In sum, existing shutter exists relatively poor defective of air permeability and problem.

The utility model content

The utility model technical problem to be solved provides a kind of air permeability shutter preferably.

For solving the problems of the technologies described above, the utility model provides a kind of shutter, comprising: framework; A plurality of outer leafs, being arranged between the said framework of horizontal space, two ends are connected with said framework through axle; A plurality of intra vanes, corresponding setting with said outer leafs; Driving mechanism is connected with said through-drive, makes said axle with positive and negative direction rotation, and the forward or reverse along with said axle makes said outer leafs and said intra vane be in the state of opening or closing; Said outer leafs and said intra vane form angle each other when being in open mode, said angle is an acute angle.

Said driving mechanism comprises connecting rod, and one in said connecting rod and said outer leafs or the said intra vane is connected,

Exercisable upper and lower the moving of said connecting rod makes said outer leafs and said intra vane open or close, and said outer leafs is connected through driving connector with said intra vane.

Said driving connector comprises the outer impeller and the interior impeller of mutual meshing cooperation, and said outer impeller is connected with the axle of said outer leafs end, and said interior impeller is connected with the axle of said intra vane end.

Compared with prior art, the beneficial effect of the utility model is:

Because the shutter of the utility model outer leafs and intra vane when open mode form angle each other, thereby have increased air intake passage, strengthened the performance of ventilating of shutter, so the utility model air permeability are better.

Description of drawings

Describe the embodiment of the utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the structural representation of the utility model under in off position.

Fig. 3 is the structural representation of the utility model under open mode.

Fig. 4 is the lateral view of the utility model.

Among the figure: framework 10, outer leafs 12, intra vane 14, driving mechanism 16, connecting rod 18, angle 19, outer impeller 20, interior impeller 22.

The specific embodiment

As shown in Figure 1; A kind of shutter; Include rectangular frame 10, outer leafs 12, intra vane 14 and driving mechanism 16; Being arranged between the framework 10 of wherein a plurality of outer leafs 12 levels and space, intra vane 14 and outer leafs 12 corresponding settings, the two ends of each outer leafs 12 and each intra vane 14 all are installed between the framework 10 through axle; Driving mechanism 16 includes connecting rod 18; This connecting rod 18 is connected with the axle of each outer leafs 12 1 end; These connecting rod 18 exercisable moving up and down; The axle that makes outer leafs and intra vane end is with the rotation of positive and negative direction, and along with the forward or reverse of axle, makes outer leafs 12 and intra vane 14 be in the state of opening or closing; The special feature of the utility model is: when outer leafs 12 and intra vane 14 are in open mode, form angle 19 each other; Preferred above-mentioned angle 19 is an acute angle, and the realization of above-mentioned angle 19 depends on following structure: an outer impeller 20 is installed on the axle of each outer leafs 12 end, corresponding on the axle of each intra vane 14 end impeller 22 in the installation; Outer impeller 20 and interior impeller 22 mutual meshing cooperations; During operator link 18, at first the axle of connecting rod 18 each outer leafs 12 end of drive just changes, and each outer leafs 12 is slowly opened; The revolving force that is positioned on outer leafs 12 end axis is passed on the axle of intra vane 14 ends with impeller 22 through the outer impeller 20 that cooperatively interacts successively; Make intra vane 14 and outer leafs 12 interlock Unscrews, when outer leafs 12 is in when opening shape fully the angle with 45 ° of horizontal plane formation, and intra vane 14 just is in level; Be to have formed angle 19 between outer leafs 12 and the intra vane 14; This structure design has effectively been eliminated the air intake obstruction, has increased air intake passage 15, thereby has strengthened the performance of ventilating of shutter.

In sum, the performance of ventilating of the utility model is better.

The above is merely the preferred embodiments of the utility model; The protection domain of the utility model does not exceed with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
