Detailed Description
As shown in fig. 1, the built-in sunshade hollow blind of the present embodiment is mainly composed of a sealed hollow glass 1, a blind 2 provided in the hollow glass 1, and a blade retracting mechanism 3 for controlling the raising and lowering of the blades 22 of the blind 2, and a blade turning mechanism 4 for controlling the turning of the blades 22.
The hollow glass 1 is known and comprises a glass 10, a first frame 11 positioned on the upper side and the lower side of the glass 10 and a second frame 12 positioned on the left side and the right side of the glass 10, wherein the four frames are rectangular and hollow frames, and the interiors of the frames are communicated. Blind 2 is also known and comprises a sill 20, a ladder cord 21, a plurality of vanes 22, etc.
Specifically, the blade retracting mechanism 3 includes a first inner magnet slider 30 disposed in the hollow glass 1 and slidably disposed along the length direction of the second frame 12, a movable pulley 31 connected to the upper portion of the first inner magnet slider 30, two lifting ropes 32, a lifting pulley 33 disposed above the blind 2 and in one-to-one correspondence with the lifting ropes 32, a fixed pulley 34, and a first outer magnet slider disposed outside the glass and configured to drive the first inner magnet slider to slide. These specific structures may be referred to as 201110277348.1, which will not be repeated here.
Specifically, the blade turning mechanism B includes an upper page turning wheel 40 located at the boundary position between the first frame 11 and the second frame 12, a lower page turning wheel 41 located below the upper page turning wheel 40, a page turning pull rope 42 winding the upper page turning wheel 40 and the lower page turning wheel 41, a second inner magnet slider 43 slidably disposed on the second frame 12, a second outer magnet slider (not shown in the figure) located outside the glass 10 and used for driving the second inner magnet slider 43 to slide, a page turning shaft 44 with two ends fixedly connected with the upper page turning wheels 40 on two sides respectively, two page turning control wheels 45 fixedly disposed on the page turning shaft 44, and two page turning seats 46 (the number of the page turning control wheels and the page turning seats depends on the width of the blind, and the number of the page turning control wheels and the page turning seats increases correspondingly). The specific above structure can be further seen in 201110277348.1, which will not be repeated here.
In this example, just in order to integrate the upset and the receipts of blind 2 together, so, not only can realize the upset and receive and release of blind 2, further simplified the structure of product moreover, by a wide margin reduce cost is also favorable to the packaging efficiency of product, simultaneously by the combination of movable pulley and movable pulley for blind 2 is very laborsaving in the motion process, consequently, the life of rope sheave is at least twice of the product among the prior art.
Specifically, the first inner magnet slider 30 and the second inner magnet slider 43 are fixed to the same slide c, so that when the first outer magnet slider is manipulated, the second outer magnet moves synchronously, and vice versa.
