Description

Technical Field

[0001] The utility model relates to the technical field of blinds, in particular to an easily detachable external sunshade device for blinds. Background Technique

[0002] Blinds are generally relatively wide and are generally used for indoor and outdoor sunshading and ventilation. The increasingly recognized louver curtain wall also evolved from blinds. The louver curtain wall has many functional advantages and is very beautiful. It is generally used in high-rise buildings. After retrieval, the patent with the publication number CN107288524B discloses an easily detachable intelligent external sunshade device for blinds. When in use, it can be easily installed and disassembled without damaging the external wall and without requiring the space requirements between the top of the broken bridge window and the roof. Compared with the existing multi-blade assembled blinds for anti-glare, it has a simple and light structure, convenient operation, uses internal and external light sensors to compare with the standard illuminance value, and compared with the existing intelligent sunshading system, the processor has less computing power, requires fewer various parameters, and has high calculation reliability. However, the width of its louver blades is not convenient for compression. When it is needed indoors, after adjusting the louver blades to a certain angle, the daylighting can be maximized. However, as time goes by, the sunlight irradiation angle tilts, so the louver blades will form a blockage. As time goes by, the blockage problem becomes more and more serious. Therefore, an easily detachable external sunshade device for blinds that is convenient for shrinking the louver blades and reducing the impact on indoor daylighting is designed.
