The specific embodiment

In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.

First, refer to shown in Fig. 1, it is upper that the utility model embodiment cooperation is installed on a window frame A, mainly includes the first scroll bar 1, the second scroll bar 2, cord 3 and guide seat 4, wherein:

The first scroll bar 1, its two ends are respectively equipped with one first holder 11, this two first holder 11 is fixed on the top place of this window frame A relatively, so as to this first scroll bar 1 can be rotated with respect to this first holder 11, and in the two ends of this first scroll bar 1 near these two first holders, 11 positions, being respectively equipped with the section of a dwindling 12(please refer to shown in Fig. 5), the diameter of this two section of dwindling 12 is less than the diameter of this first scroll bar 1, this first scroll bar 1 is a driven shaft again, its inside is provided with an elasticity unreeling mechanism, for be able to automatic rewinding under the state that is not subject to External Force Acting, this elasticity unreeling mechanism is a known techniques, hereby do not repeat.

The second scroll bar 2, it is fixedly installed with respect to this first scroll bar 1, the two ends of this second scroll bar 2 are respectively equipped with one second holder 21, this two second holder 21 is fixed on the below place of this window frame A relatively, so as to this second scroll bar 2 can be rotated with respect to this second holder 21, and in the two ends of this second scroll bar 2 near these two second holders, 21 positions, be provided with a spiral grooves 22, this second scroll bar 2 is a driving shaft again, its inside is provided with a power-driven mechanism, be able to automatic rotating for producing a power, this power-driven mechanism is a known motor structure, hereby do not repeat.

Cord 3, it is fixed between this first scroll bar 1 and this second scroll bar 2, this cord 3 is provided with a first end 31 and one second end 32, wherein this first end 31 is fixed on this first scroll bar 1, and this second end 32 is provided with at least one serving 33, in the present embodiment, be provided with two servings 33, one end of this two serving 33 is fixed on the second scroll bar 2, furl in the spiral grooves 22 at these the second scroll bar 2 two ends for being wound around, the both sides of this cord 3 are respectively equipped with a stop section 34(as shown in Figure 2 again), this stop section 34 can be the structure of the braid over braid (TAPE) of a slide fastener, for furling in the section of dwindling 12 at these the first scroll bar 1 two ends, this stop section 34 is provided with at least more than one block 35(that is the arrangement of slide fastener zigzag as shown in Figure 3 again), this block 35 can be the structure of the sprocket (TEETH CHAIN) of a slide fastener.

Guide seat 4, it is relatively arranged on the both sides of this cord 3, this guide seat 4 is provided with two groups, and be relatively fixed on respectively the both sides of this window frame A, and between this first scroll bar 1 and this second scroll bar 2, this two guide seat 4 is with respect to the stop section 34 of these cord 3 both sides and be respectively equipped with a slide rail 41, this two slide rail 41 can be established respectively in wherein carrying out slippage for the block 35 of these cord 3 stop sections, both sides 34, this two slide rail 41 is provided with an open slot 42 relatively again, the A/F of this open slot 42 is less than the width of this block 35, but be greater than the thickness of this stop section 34, so as to this cord 3 can be passed through and smooth and easy scrolling by this stop section 34 in the interior slippage of this open slot 42, and this block 35 cannot be passed through by this open slot 42, and emerge in outside this slide rail 41.

When use, as shown in Figures 1 and 3, after this second scroll bar 2 starts to start, can rotate with respect to this second holder 21, and can pull two stay cords 33 of this

cord

3, 33 of this two stay cords can be furled in the spiral grooves 22 at these the second scroll bar 2 two ends, and seeing through this two stay cord 33 can drive this cord 3 to launch by drawing, this cord 3 can synchronously drive this first scroll bar 1 to rotate with respect to this first holder 11, and this cord 3 is while launching, 35 of the blocks of these cord 3 stop sections, both sides 34 can be in the interior relative slippage of the slide rail of this two guide seat 4 41, be greater than the A/F of these two slide rails, 41 open slots 42 by the width of this block 35, and the thickness of this stop section 34 is less than again the A/F of this open slot 42, therefore this cord 3 is in the time of slippage, the stop section 34 of its both sides can be in the smooth and easy slippage of this two slide rail 41, and this block 35 also cannot be passed through by this open slot 42, and emerge in outside this slide rail 41, until after this cord 3 launches completely, this second scroll bar 2 just stops operating, so as to utilizing this cord 3 can cover the window A1 on this window frame A completely, again in the time that this cord 3 launches, once be subject to blowing or the External Force Acting impact such as artificial collision of wind-force, can utilize equally the width of this block 35 to be greater than the A/F of this open slot 42, therefore this block 35 cannot be passed through by this open slot 42, and emerge in outside this slide rail 41, therefore, can make this cord 3 keep smooth expansion, and furl operation after can not having influence on.

Again in the time that needs furl cord 3, as shown in Figure 4, as long as this second scroll bar 2 of reverse scrolling, so as to unclamping two stay cords 33 of this cord 3, and this first scroll bar 1 can utilize its inner elasticity unreeling mechanism, for in the time not being subject to this second scroll bar 2 and seeing through the pulling force traction of cord 3 and stay cord 33 thereof, can this cord 3 of automatic rewinding, be greater than again the thickness of this cord 3 due to the thickness of stop section 34 of these cord 3 both sides and the width of block 35 thereof, therefore when this cord 3 is furled on this first scroll bar 1, these block 35 indentations are arranged, therefore can easily be furled in the section of dwindling 12 at these the first scroll bar 1 two ends (as shown in Figure 5), utilize the diameter of this two section of dwindling 12 to be less than the diameter of this first scroll bar 1, therefore these stop sections 34 and block 35 can be furled in this two section of dwindling 12 because of the additional space of small diameter institute in, make these stop sections 34 and block 35 thereof after furling, still can keep flushing with the external diameter after this cord 3 furls, exceed because of stop section 34 and block 35 and do not have, and produce excessive thickness, therefore can keep furling smooth and easy smooth.

The foregoing is only one of them embodiment of the utility model; when not limiting patent protection scope of the present utility model with this; such as the simple equivalence of doing according to claim of the present utility model and description changes and replaces, and all should still belong in the scope of the utility model protection that claim contains.
