Shutter sunshading device capable of being packed up

Abstract

The invention discloses a shutter sunshading device capable of being packed up. The shutter sunshading device comprises louvre blades, a support and a louvre blade opening device, wherein the support is hinged to the upper portion of a window or a glass curtain wall and can extend outwards. Hollow struts are arranged on the two sides of the support. Guiding rails are arranged inside the struts, sliding blocks capable of sliding along the guiding rails are arranged on the guiding rails. The sliding blocks are connected with a driving device which is used for driving the sliding blocks to slide up and down along the guiding rails and for supporting the struts. The driving device comprises a supporting rod I and a supporting rod II, wherein the supporting rod I is hinged to the lower portion of the window or the glass curtain wall, and the supporting rod II is movably connected with the sliding blocks. The supporting rod II is arranged inside the supporting rod I in a sleeved mode through a thread, and a rotating device for driving the supporting rod II to rotate and capable of extending outwards is arranged inside the supporting rod I. The shutter sunshading device capable of being packed up is simple in structure and light in weight and can be opened and packed up by the manner that the shutter sunshading device capable of being packed up is installed on the upper portion of the window or the glass curtain wall, and sunshading and dazzle prevention are convenient while indoor ventilation and natural lighting are not affected.

[0002] Windows are an important part of modern architecture. Through windows, indoor personnel can receive light, ventilation, decoration and view. More and more buildings use glass curtain walls made of large areas of glass. In hot summer, this kind of glass curtain wall can The sunlight entering the room through the glass curtain wall will cause a huge heat load, resulting in too high indoor temperature and high energy consumption of air conditioners. Usually, people mainly use inner sunshade, glass film and outer sunshade to prevent direct sunlight. The inner sunshade is like a curtain. Or internal louvers for shading, but can not meet the shading and ventilation at the same time, and can not get the view through the glass curtain wall when shading; the glass film is expensive and difficult to popularize; although the general fixed external shading device has a good shading effect, it is heavy and heavy. It is easy to fall and cause safety accidents, especially in windy and snowy weather
