Abstract

A building external sunshade wind resistance venetian blind driven by a side chain comprises louvre blades (29) and a motor (4). The louvre blades are all connected with a rotating chain (22) through a fork type connecting rod (21). The rotating chain and a rotating steel wire rope (10) are fixedly connected. A coil sleeve (7) is provided with a pawl (8) which is matched with a ratchet wheel (12). The centre shaft (12-1) of the ratchet wheel (12) is sleeved in the center hole (15-3) of a chain wheel (15). One end of a transmission torsion spring (13) abuts against a square key (15-2) of the chain wheel (15). The other end of the transmission torsion spring (13) abuts against an arc link stopper (12-2) of the ratchet wheel (12). A lifting chain (17) is meshed with the chain wheel (15). The chain (17) is connected with a small sliding block (18) and a big sliding block (25). The big sliding block (25) is connected with the bottom louvre blades (29) through a bottom hook (26). The building external sunshade wind resistance venetian blind driven by the side chain not only has good sunshade wind resistance functions but also has noise reduction, heat preservation and theft-proof functions.

Description

technical field [0001] The invention relates to a building energy-saving product, in particular to a building shutter, in particular to a sun-shading and wind-resistant blind outside a building driven by a side chain. Background technique [0002] As we all know, building external sunshade is an important sub-item of building energy saving today. Research and test data show that the use of external sunshade products in buildings in summer can save 20-30% of the electricity used for refrigeration and air conditioning, and the energy-saving effect is remarkable. Today, the products used for building external sunshade in China are mainly venetian blinds, roller blinds, awnings, etc. Among them, although the venetian blinds have perfect functions such as sunshade, ventilation, and lighting, the wind resistance of the slats is slightly weaker, and the ropes that control the movement of the slats The weather resistance of the system is not good and there are gaps between the lou...
