Abstract
The invention relates to a louvre blade capable of forming an air backflow cavity. The louvre blade capable of forming the air backflow cavity comprises a front louvre plate and a rear louvre plate with similar shape, wherein the front louvre plate and the rear louvre plate are both shaped like a ladder of which the upper part is perpendicular and the part below the middle part is downward oblique; the lower end of the front louvre plate is perpendicularly provided with a front baffle plate; the front louvre plate and the rear louvre plate are vertically arranged in parallel, and are connected by a connecting plate between the front louvre plate and the rear louvre plate. The louvre blade capable of forming the air backflow cavity is rational in design, simple in structure and convenient to install; not only are the direct irradiation of sunshine and the splash of rain water prevented, but also a problem of direct wind blowing can be prevented; therefore, air flows more gentle, and the indoor environment is more comfortable.
Description
Technical field
The present invention relates to a kind of building unit, especially a kind of louvre blade, specifically a kind of louvre blade forming air backflow cavity.
Background technology
At present, outside the forms of building, fixing blinds is installed, the effect that solar control direct projection and rainwater are splashed into can be played.The louvre blade of current use mostly is one chip, by downward-sloping for blade certain angle during installation.But, although this blinds can solar control direct projection and rainwater, the problem of straight blowing can be caused, make indoor to feel uncomfortable.
Summary of the invention
The object of this invention is to provide one and overcome the deficiencies in the prior art, make blinds can not only solar control direct projection and rainwater, more can make the louvre blade of the soft ventilation of indoor acquisition.
Technical scheme of the present invention is:
Form a louvre blade for air backflow cavity, comprise the similar front impeller of shape and rear impeller; The shape of described front impeller and rear impeller is upper vertical, and upper end slightly bends, and middle part is downward-sloping stepped below; The lower end of described front impeller is vertically provided with a front apron; Described front impeller and rear impeller vertically be arranged in parallel, and are connected by a plate between the impeller of front and back.
Described rear impeller is a little more than front impeller.
Described junction plate is vertical herringbone, its upper vertical, and upper end slightly bends; The top of described junction plate and the top of front impeller fit, and lower end is connected to the position of rear impeller close to bottom.
The transverse sides of described front impeller, rear impeller and junction plate is equipped with some fixing holes.
Beneficial effect of the present invention:
The present invention is reasonable in design, and structure is simple, easy for installation, not only has and prevents Yanguan Pass direct projection and rainwater to be splashed into, and can avoid the problem of straight blowing, and air is flowed and more relaxes, indoor are more comfortable.
Accompanying drawing explanation
Fig. 1 is horizontal end view of the present invention.
Fig. 2 is assembling schematic diagram of the present invention.
Wherein: impeller before 1-; 2-front apron; Impeller after 3-; 4-junction plate; 5-fixing hole; The horizontal frame of 6-.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, the front impeller 1 that shape of the present invention is similar and rear impeller 3.The shape of described front impeller 1 and rear impeller 3 is upper vertical, and upper end slightly bends, and middle part is downward-sloping stepped below.The lower end of described front impeller 1 is vertically provided with one piece of front apron 2.Described front impeller 1 and rear impeller 3 vertically be arranged in parallel, and rear impeller 3 is a little more than front impeller 1.Be connected by one piece of junction plate 4 between the impeller of front and back.Described junction plate is vertical herringbone, its upper vertical, and upper end slightly bends.The top of described junction plate and the top of front impeller fit, and lower end is connected to the position of rear impeller close to bottom, make the angle forming about 90 degree between the bottom of junction plate and front impeller.The transverse sides of described front impeller 1, rear impeller 3 and junction plate 4 is equipped with several fixing holes 5.
During installation, with screw through the fixing hole on louvre blade, be tightened on vertical frame.Period, guarantee that the upper end of impeller is mutually concordant with the rear impeller lower end of previous louvre blade after each louvre blade, as shown in Figure 2.Meanwhile, make the rear impeller upper end of a slice louvre blade topmost close to upper horizontal frame, the front apron lower end of the louvre blade of bottom a slice is close to lower horizontal frame.Like this, blinds after assembling not only can solar control direct projection and rainwater be splashed into, and yet forms both an air backflow cavity between adjacent two panels louvre blade, and the air that outside is blown into slows down in this flowing, enter indoor air and therefore become soft, what make indoor feels more comfortable.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
