Movable curtain capable of achieving external sunshade

Abstract

The invention discloses a movable curtain capable of achieving external sunshade, which relates to the field of external sunshade. Rollers on a lead rail are driven to roll when a stay cord is pulled, and meanwhile, curtain cloth is driven to rotate to the outdoor side from the indoor side after passing through notches in a window frame so as to achieve external sunshade. The movable curtain mainly comprises the lead rail fixed on the window frame, the rollers, stay cords, clips, guide wheels, and the curtain cloth, wherein the stay cords are connected with connecting rods of the rollers; the clips are connected to the connecting rods of the rollers; the notches are formed in the left and right half sides of the upper end of the window frame, respectively; the rollers are embedded in the lead rail and can roll on the lead rail. The movable curtain can be applied to external sunshade, also can be used as a common indoor curtain, can effectively alleviate solar radiation in summer, is an external sunshade curtain which is simple to fabricate, convenient to operate and use, economic and practical, and has a good energy-saving effect.

Description

technical field [0001] The invention relates to the field of window shading, in particular to a movable curtain capable of realizing external shading. Background technique [0002] Windows are an essential part of a building. External windows are thin-walled and lightweight components. The energy consumption of windows accounts for about half of the energy consumption of the entire building. It is the weak link with the largest loss of building energy consumption. The performance is relatively poor. In addition, the air infiltration through the window gap, especially the solar radiation heat transfer through the window in summer, has a great impact on the comfort of the indoor thermal environment, greatly increasing the load and energy consumption of heating and air conditioning. , The energy-saving effect of windows is directly related to the energy consumption of buildings. The shading effect of windows has a great influence on the heat gain of solar radiation, and the di...

Problems solved by technology

The invention patent of CN101713276 "An adjustable external sunshade device" is equipped with a reel on the outside of the double-layer hollow glass frame, and a pull-bead rope on the inside. The pull-bead rope passes through the first guide wheel and the second guide wheel. It is connected with the reel, and the sunshade fabric on the reel can be released by pulling the bead rope to achieve the purpose of sunshade. Obviously, the sunshade fabric of this device is always placed on the outdoor side, and is always placed in the sun, wind and rain. In the environment, it is easy to cause corrosion and damage to the curtain fabric, so the service life is limited; in addition, most of the entire device is on the outdoor side, which is inconvenient to install and maintain
