Abstract

The utility model relates to an environment-friendly light-dimmer curtain support used for sight impaired people to adjust light rays in reading and belongs to the technical field of assistance devices in learning for the people with low vision. The environment-friendly light-dimmer curtain support is composed of a frame and shielding things. The frame comprises a curtain rod, lifting ropes, pulling lines and check rings. Shaft gears are respectively arranged on two ends of the curtain rod. Stretching and pulling of the lifting ropes and operations of an upper shielding curtain, a middle shielding curtain and a lower shielding curtain do not interfere with each other. Through changes of shielding positions and shielding areas of the upper shielding curtain, the middle shielding curtain and the lower shielding curtain, the environment-friendly light-dimmer curtain support achieves adjustment of angles and intensity of sunlight when people read books. The environment-friendly light-dimmer curtain support can facilitate reading and writing on the condition of saving electric light sources, can prevent eyestrain and improve reading speed and writing speed, can also be used for common people and is energy-saving and environment-friendly.

Description

A kind of environmental protection light-regulating window curtains frame

Technical field

The utility model belongs to low eyesight crowd and learns the accessory technical field, be mainly used in low eyesight crowd in the adjustment of reading books luminous intensity in time, can under the condition of saving electric light source, read easily and write, specifically relate to a kind of a kind of environmental protection light-regulating window curtains frame that helps low Visual Acuity People to read.

Background technology

It is single horizontal folding or the form that draws high up and down basically that existing curtain opens and closes, can not free adjustment to the area and intensity of injecting light angle in the window, injecting light, use the reading under illumination of this kind curtain to be a great inconvenience for low eyesight personage.Sunlight all enters, and light is can be too strong and dazzle the eyes, and stops that fully light is too dark, even in the situation by day, also need turn on the ligthing paraphernalia such as electric light during reading and wastes energy.Because the low special eyesight status of eyesight personage has special requirement to light when reading books, can not be too bright, can not be too dark, and the angle of light also had specific demand.Therefore the curtain of conventional structure is not looked after low eyesight crowd, can not satisfy this crowd's special requirement.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, provide a kind of sunlight of regulating easily to inject angle and intensity curtain, it is mainly used in low eyesight crowd in the adjustment of reading books luminous intensity in time, can under the condition of saving electric light source, make things convenient for read purposefully and write, can prevent eye fatigue, can improve again and read and writing rate.

Technical solution of the present utility model is: a kind of environmental protection light-regulating window curtains frame is comprised of framework and shelter, and framework comprises curtain rod, lifting rope, backguy, back-up ring.The two ends dress of curtain rod has respectively stem gear, and lifting rope is selected flexible wire.

Shelter comprises three groups of check apron combinations that structure is identical, is respectively upper check apron, upper check apron gear train, upper check apron backguy; Middle check apron, middle check apron gear train, middle check apron backguy; Lower check apron, lower block gear train, lower check apron backguy.Three groups of gears and the fixed coaxial installation of curtain rod spur respectively the three groups of check aprons in upper, middle and lower by three backguys, and check apron uses lucifuge, folding material, makes shelter have retractable.

Because the utility model is comprised of framework and shelter two parts, the operation of three groups of check aprons of the stretching of lifting rope and upper, middle and lower does not interfere with each other, by the variation of blocking position and area of the three groups of check aprons in upper, middle and lower, be implemented in the adjustment of reading books optic angle in time degree and intensity.
