TECHNICAL FIELD
[0001] The utility model relates to a movable roller shutter device, especially a movable roller shutter device which can form double air layers with an outer window to greatly improve the heat preservation and insulation performance of the outer window. BACKGROUND
[0002] The outer window is a weak link of the heat preservation and insulation of the building envelope structure, and its heat preservation performance is only one tenth to one hundredth of that of the outer wall. At present, the energy-saving window of the building outer window mostly adopts single-cavity or double-cavity hollow glass with heat-breaking profiles, and the heat transfer coefficient is generally not less than 2.0 W / (m 2 ·K). To further improve the heat preservation and insulation performance of the outer window, the number of layers of glass needs to be increased, and better heat-breaking and heat-preservation profiles need to be used, which greatly increases the cost but has a small performance improvement, has a low cost performance, and is difficult to be accepted by users. At present, residents often use cloth curtains, blinds, roller shutters and other indoor curtains to prevent heat in summer. These curtains have a certain heat insulation effect, but even thick cloth curtains cannot close the window hole and basically have no heat preservation effect. In winter, some residents spontaneously use so-called heat preservation curtains. These heat preservation curtains are not real curtains, but are roller shutter cloth made of PVC (polyvinyl chloride) film, PEVA (polyethylene-vinyl acetate) film or polyester fiber composite fabric, and are pasted around the indoor window hole with magic tape with back glue to form a closed air layer with the outer window, thereby having a certain heat preservation effect, but the heat preservation performance is not greatly improved. The heat preservation curtain is fixedly pasted on the window hole and cannot be flexibly opened and closed as needed, which affects the appearance to some extent. SUMMARY
[0003] The utility model aims at the shortage of the prior art and provides a movable roller shutter device which forms double air layers with an outer window to greatly improve the heat preservation and insulation performance of the outer window.
[0004] The utility model adopts the technical scheme: a movable roller shutter device for improving the heat preservation and insulation performance of an outer window, which comprises a window hole, an outer window and a movable roller shutter device.
[0005] An outer thermal insulation system is arranged on the outer side of the wall around the window hole, and an inner plaster layer is arranged on the inner side; the window hole is provided with an outer window, the outer window comprises outer window glass and outer window profiles, and the outer window is connected to the window hole by using an attached frame;
[0006] The movable roller shutter device is installed on the inner side of the outer window at the window hole, and comprises a curtain box, a curtain roller, a roller shutter cloth, a limiting roller, a gravity roller, a vertical limiting groove and a base groove.
[0007] The curtain box is fixed to the wall above the window hole by anchor bolts, and the curtain roller and the limiting roller are installed in the curtain box.
[0008] The double-layer curtain fabric is folded in vertical direction, the upper end of the curtain fabric is wound on the curtain roller, and the two layers of the curtain fabric are separated and kept a certain distance by two spaced limiting rollers, and the lower end of the curtain fabric is hung by a gravity roller with the same diameter as the distance between the two layers of the curtain fabric to ensure the up-and-down movement of the two layers of the curtain fabric.
[0009] The vertical limiting groove is installed on the two side walls of the window hole chamber, and is used for limiting the horizontal swing of the curtain fabric.
[0010] The base groove is installed on the indoor window sill of the lower part of the window hole, and is used for accommodating the lower end of the curtain fabric hung by the gravity roller.
[0011] Preferably, the two sides of the curtain fabric are arranged in the vertical limiting grooves, and the lower end is arranged in the base groove when the movable curtain device is completely closed, and the movable curtain device and the outer window form two closed air layers, i.e., air layer one and air layer two.
[0012] Preferably, the curtain box is made of wood, plastic or other thermal bad conductor materials, and soft hair is arranged on the contact part between the curtain box and the curtain fabric.
[0013] Preferably, the curtain roller is driven by an internal tubular motor.
[0014] Preferably, the curtain fabric is made of double-sided silver-white fabric with thermal reflection function or composite fabric with aluminum foil.
[0015] Preferably, the vertical limiting groove is made of wood, plastic or other thermal bad conductor materials, and the cross section is [shape, soft hair is arranged on the contact part between the vertical limiting groove and the curtain fabric, and the vertical limiting groove and the inner side wall of the window hole chamber are connected by bonding, anchor bolt or shot pin.
[0016] Preferably, the base groove is made of wood, plastic or other thermal bad conductor materials, and the base groove and the window sill are connected by bonding, anchor bolt or shot pin.
[0017] The working state of the movable curtain device includes three states, i.e., completely closed, partially collected and completely collected. When the movable curtain device is completely closed, the lower end of the double-layer curtain fabric and the gravity roller are arranged in the base groove, and the two sides are arranged in the vertical limiting groove, so that the movable curtain and the outer window form two closed air layers, and good heat preservation performance is ensured. When the movable curtain device is partially collected, the lower end of the double-layer curtain fabric and the gravity roller are arranged at a position of part of the window height, so that the light collection and ventilation of the outer window are ensured. When the movable curtain device is completely collected, the double-layer curtain fabric is collected to the lower end of the curtain box by the curtain roller, so that the light collection and ventilation of the outer window are ensured.
[0018] The movable curtain device has the following beneficial effects:
