Multifunctional curtain

Abstract

The invention provides a multifunctional curtain. The multifunctional curtain comprises an upper scroll set, two side edge frames, a curtain cloth set and a lower edge frame; the upper scroll set comprises a main scroll and secondary scrolls, a main scroll tube sleeving the outer side of the main scroll, and multiple secondary scroll tubes; a main pull rope is tightened at one end of the main scroll, and is used for pulling each scroll tube to rotate; each secondary scroll tube is of a tubular structure opened at two ends and with two-layer side walls; cavities for accommodating curtain clothare formed between the two-layer side walls; the secondary scrolls movably sleeve the outer side of a fixed shaft; secondary pull ropes for driving the secondary scrolls to rotate and horizontally move are tightened on the secondary scrolls; through the main pull rope and the secondary pull ropes, the secondary scrolls are positioned in the inner side walls of different secondary scroll tubes, anddrive the corresponding curtain cloth to rotate; the side edge frame comprises inner and outer edge frames connected through flexible strips; and magnetic strips are oppositely arranged on the innersides of the inner and outer edge frames. The curtain effectively improves the insulation tightness of an outer window, can achieve such functions as insulation, mosquito prevention, sunshading or sound insulation through switching of different curtain cloth according to demands, and is convenient to operate and recyclable.

Description

technical field [0001] The invention belongs to the field of energy saving of building enclosure structures, and in particular relates to the technical field of thermal insulation and airtightness inside exterior windows of houses. Background technique [0002] At present, the external windows in many areas are single-frame and single-glass, and the heat loss of heating in winter is large, so thermal insulation and energy-saving renovation is required. In the energy-saving renovation, if the insulation method of hollow double glass is adopted, the above problems can be effectively solved, but for rural houses, there are problems such as high cost and large engineering volume, which are difficult to promote on a large scale. At the same time, because of the functions of lighting and ventilation, the external windows have changing requirements in different seasons, such as lighting requirements during the day, privacy and shelter requirements at night, ventilation and anti-mos...
