Outdoor wind resistant vertical blind

Abstract

The invention relates to an outdoor wind resistant vertical blind which comprises a semi-opened housing, a left clamping seat and a right clamping seat, wherein the left clamping seat and the right clamping seat are simultaneously fixed with the housing and a wall body; the housing is internally provided with a cloth winding drum, a square shaft, a gear case component and a circular shaft, and the square shaft, the gear case component and the circular shaft are respectively in transmission connection with both ends of the cloth winding drum; both ends of the housing are fixed and closed by a left end cover and a right end cover; a tarpaulin assembly is connected between the cloth winding drum and a vertical cloth pipe; a left slide block and a right slide block which are connected at both ends of the vertical cloth pipe as well as cloth edge guide pipes are arranged in a left slide rail and a right slide rail which are plugged with the left clamping seat and the right clamping seat and fixed with the wall body; the cloth edge guide pipes pass through the left slide block and the right slide block and are connected with the tarpaulin assembly; one end of a pull rope mechanism is connected with the square shaft and the circular shaft, while the other end is connected with the vertical cloth pipe through the left slide rail, the right slide rail, a pulley, a slide block and a tension spring; and the reversely wound tarpaulin and the pull rope are folded or unfolded through an indoor or outdoor manual control mechanism connected with the gear box component. In the invention, the tarpaulin can remain at any position, because the cloth edge guide pipes are sleeved at both the left side and the right side of the tarpaulin and slide along the cloth edge guide rails, the vertical blind has safe use and good wind resistance and is suitable for a window of a high-rise building.

Description

technical field [0001] The invention relates to an outdoor vertical curtain, in particular to an outdoor wind-resistant vertical curtain. Background technique [0002] The vertical curtain widely used at present all is to be installed in the window, and it just plays the effect of a kind of curtain. According to the tests of domestic and foreign energy conservation and emission reduction research institutions, the curtains installed in the windows can only block visible light, but the heat energy brought by the light has already penetrated the glass and caused the room to heat up. Studies have shown that if a fabric awning is installed outdoors, more than 85% of the heat energy brought by light can be blocked. For this reason, governments at all levels at home and abroad regard building outdoor sunshade systems as an important measure for energy saving and emission reduction. For example, Jiangsu Province has made a rigid regulation in 2009: all commercial houses must be e...
