Construction outdoor sun-shading metal roller blind with turnover blind slats

Abstract

The invention provides a construction outdoor sun-shading metal roller blind with turnover blind slats. The construction outdoor sun-shading metal roller blind comprises a tubular motor (10), a front housing (2), a back housing (1), a group of hoisting belts, a group of the blind slats, blind slat lateral covers (19), a turnover control mechanism and a guide rail (9), wherein the group of the hoisting belts are responsible for transmitting power of a transmission tube (22) to the blind slats; the bind slates have sun-shading effect and can be rolled on the transmission tube (22); the blind slat lateral covers (19) are arranged at the both ends of upper blind slats (4), transition blind slats (5) and turnover blind slats (6), and are in the same symmetrical structure; the upper blind slats (4), the transition blind slats (5) and the turnover blind slats (6) can be connected by a hoisting chain board (8) and a turnover chain board (7) through the blind slat lateral covers (19), so that the upper blind slats (4), the transition blind slats (5) and the turnover blind slats (6) form a straight line capable of stretching, and can be wound on the transmission tube (22) in a curled manner; and meanwhile, the turnover blind slats (6) is turned over to be horizontal, so that light enters indoors through gaps among the turnover blind slats. The construction outdoor sun-shading metal roller blind provided by the invention keeps the advantages of good sun-shading effect, strong wind-resistance capability, and obvious sound insulation effect. The blind slates can be turned over while the construction outdoor sun-shading metal roller blind is unfolded for sun-shading, so that the functions of lightning, ventilating, keeping a visual field and the like are realized.

Description

technical field [0001] The invention relates to a building sunshade product, in particular to a building exterior sunshade aluminum alloy roller blind whose curtain pieces can be vertically lifted and turned over, in particular to a building exterior sunshade metal roller blind whose curtain pieces can be turned over. Background technique [0002] Test data show that the energy consumption in traditional buildings accounts for about one-third of the energy consumption of the whole society, which has attracted great attention from all over the world and promoted the rapid development of the building energy-saving industry. Building external shading is an important branch of the building energy-saving industry, and has become an important measure for building energy-saving in Europe. In recent years, the Chinese government has issued a policy to promote the use of building external shading technology, and has successively issued a series of standards for building external ...

AI Technical Summary

Problems solved by technology

Metal roller blinds have excellent shading effect, strong wind resistance, and remarkable sound insulation effect, but when the shading is unfolded, the beneficial functions such as lighting, ventilation, and vision cannot be realized due to the vertical interlocking of the slats; although the venetian blinds can achieve lighting, Ventilation and maintain vision, but the wind resistance is slightly weak; when the window is closed and the central sunshade is unfolded, the sunshade in the middle can realize the functions of sunshade, lighting and maintaining vision, but at this time the window is closed and ventilation is not possible ; The wind resistance of the fabric roller blind is relatively weak, and it can only be used for shading the external windows of low buildings; therefore, the functions of all kinds of external shading products on the market are not perfect
