Description
Technical Field
The present invention relates to a double-layered roller blind structure, and more particularly to an adjustable double-layered roller blind structure.
Background
Modern window curtains are in various forms, and the dimming roller shutter is a double-layer roller shutter capable of adjusting the quantity of incident light. The light-adjusting roller shutter is formed by alternately forming a plurality of sections of light-transmitting parts and light-shielding parts, and the light inlet quantity is adjusted by the relative position between the light-transmitting parts and the light-shielding parts. Therefore, when the light transmission parts are overlapped oppositely, a large amount of external light can enter the room from the light transmission parts, and in addition, when the light shielding parts are overlapped oppositely, the light can be blocked from entering the room, so that the effects of shielding light and privacy can be achieved; however, referring to fig. 8 and 9, in the conventional dimming rolling blind structure, one end of the dimming curtain fabric 41 of the rolling blind 40 is rotatably installed in a curtain frame 43 by using a rolling shaft 42, and the other end of the dimming curtain fabric passes through a counterweight rod 44 and then is folded upwards and fixed on a fixing part 431 of the curtain frame 43, so that the dimming curtain fabric 41 is in a double-layer state and is wound between the curtain frame 43 and the counterweight rod 44, and a vertical-weight sinking extending state is formed by the counterweight rod 44, thereby achieving the use purposes of indoor light transmission, dimming and shading by rolling the dimming curtain fabric 41 by using the rolling shaft 42.
The known structure is not difficult to find in detail, and has a plurality of defects, which are mainly attributed to the following reasons: the other end of the dimming cord fabric 41 of the rolling blind 40 is directly fixed to the fixing portion 431 of the curtain frame 43, so that the length of the dimming cord fabric 41 wound between the curtain frame 43 and the weight bar 44 is limited, and cannot be adjusted by a consumer according to the size of a window, and therefore, when the length of the dimming cord fabric 41 is cut and manufactured, the dimming cord fabric 41 must be very accurate, and if a certain error occurs, the dimming cord fabric 41 cannot be used and discarded, which greatly increases the manufacturing cost, the most common problem of the existing rolling blind 40 is that when the dimming cord fabric 41 is completely unfolded, each section of the shading part cannot be actually overlapped with the light-transmitting part, and therefore, the rolling blind 40 lacks the use effects of shading and privacy shielding under the complete unfolding, and therefore, the existing rolling blind 40 needs to be improved.
In view of the above, the inventor has made experience in manufacturing, developing and designing related products for many years, and has finally obtained the present invention with practical applicability after detailed design and careful evaluation aiming at the above-mentioned objects.
