Liftable external awning blind with double control arms

Abstract

A liftable external awning blind with double control arms belongs to the field of external sunshade equipment of buildings, and particularly relates to a movable external awning blind. The liftable external awning blind with the double control arms is characterized in that fixing adjusting devices are vertically mounted at two ends of each blade (4), a control arm (11) and a torsion beam (7) are connected in an encircled manner to form each fixing adjusting device which is a parallelogram frame, two ends of each blade (4) are H-shaped, the blades (4) are horizontally mounted between the two fixing adjusting devices via the H-shaped ends of the blades (4) and T-shaped grooves (5) arranged on the inner sides of the control arms (11), and one side of each fixing adjusting device is mounted outside a window of a building via a center shaft (10). The liftable external awning blind with the double control arms has the advantages of convenience in lifting and falling, high wind resistance and stability and flexibility in adjustment, is applicable to external sunshade of a plurality of buildings, and can guarantee a good sunshade effect on the premise of not affecting transmission of light.

Description

technical field [0001] The utility model relates to a double control arm type liftable external sun-shading shutter, which belongs to the field of external sun-shading equipment of buildings, and specifically relates to a movable external sun-shading shutter. Background technique [0002] The existing shutters of building doors and windows can be divided into fixed type, sash opening type, sash translation type and blade rotation type. The blades cannot move vertically or parallelly, which will affect the permeability and openness of the line of sight, as well as lighting and ventilation; while the blades The movable external shading system is to install the shading equipment on the outside of the window of the building. Compared with the internal shading curtains, the external shading, especially the external shading curtains, can block the heat, ultraviolet rays, and strong light outside in the first time, and reduce the indoor temperature. It has an excellent effect of sh...

Problems solved by technology

[0002] The existing shutters of building doors and windows can be divided into fixed type, sash opening type, sash translation type and blade rotation type. The blades cannot move vertically or parallelly, which will affect the permeability and openness of the line of sight, as well as lighting and ventilation; while the blades The movable external shading system is to install the shading equipment on the outside of the window of the building. Compared with the internal shading curtains, the external shading, especially the external shading curtains, can block the heat, ultraviolet rays, and strong light outside in the first time, and reduce the indoor temperature. It has an excellent effect of shading and energy saving, but the existing external shading products are technically immature. While shading, it is easy to reduce the indoor light transmittance and ventilation effect, and cannot fully take into account sunshading, wind resistance, Light transmission and ventilation requirements

[0003] Although there are also shutters with rotatable blades, such as the Chinese patent application No. 200820108953.X, a sunshade shutter with rotatable and retractable blades. In this patent, the blades can be moved and rotated, but the technical scheme is more complicated. Use and production Both are cumbersome and inconvenient to install and disassemble; the Chinese patent with the application number of 200920108807.1 also has the defect of complicated structure, and needs to use structures such as transmission device, power device and clutch device, so a correspondingly large installation space is required; Or, there is also a Chinese patent with application number 201020232502.4, which combines the window frame and sunshade frame into one design. Although the stability of the shutter blades is guaranteed, it is inconvenient to disassemble after the shutters are discarded, and not all windows All are applicable, and can only meet the use of windows with some structures. Therefore, there are limitations in the scope of use; moreover, most of the external sunshade shutters that can be raised and lowered at present are not strong in wind resistance, low in stability, and low in applicability.
