Actuation in specific region；Two upright bar 36 is set to two ends of bottom base 31 and is connected to a lifting and driving rope 34 respectively, makes this
Two lifting and driving ropes 34 when being furled by the first, second bull wheel 32,33 can respectively along two upright bar 36 axial displacement and
It can regularly and fitly be wound in the first, second bull wheel 32,33.
In addition, two guide wheel shaft 37 is set to as shown in figure 3, rope rolling unit 30 has more two guide wheel shafts 37 and two guide wheels 38
Two ends of bottom base 31 and it is adjacent to the first, second bull wheel 32,33 respectively, which is rotatably arranged in two guide wheel
On the one hand axis 37 and respectively support provide guide effect to two halliard 34, on the other hand make in a lifting and driving rope 34
The two lifting and drivings rope 34 generates tension appropriate.
Referring again to Fig. 7 and Fig. 8, in the two-layer equation ropewinder 12 of the 2nd embodiment of the invention, the first, second bull wheel
50,60 structure is unlike the embodiments above, and is not engaged transmission between the first, second bull wheel 50,60, but respectively
It is driven by the first, second wind spring gear 32,33.In details of the words:
Driving unit 20 has a top base 21, one first wind spring gear 22, one second wind spring gear in the present embodiment
23 and a wind spring 26, wherein being with previous embodiment in the place of configuration aspects difference: the first bottom plate of top base 21
212 have two bottom outlets 215, and one of bottom outlet 215, which corresponds to polygonal shaft hole 24 on the first of the first wind spring gear 22, (such as schemes
Shown in 10)；Second wind spring gear 23 is more on second with more polygonal shaft hole 25 (hexagon ring as shown in fig. 13 that) on one second
Side shape axis hole 25 corresponds to another bottom outlet 215 (as shown in figure 11) of the first bottom plate 212 of top base 21.As for the first volume
Spring gear 22 and wind spring 26 be then in structure it is identical as previous embodiment, hold do not repeat herein.
Rope rolling unit 30 in the present embodiment have a bottom base 31, one first bull wheel 50, one second bull wheel 60 and
Two lifting and driving ropes 34, wherein being with previous embodiment in the place of configuration aspects difference: the second top of bottom base 31
Plate 311 has two apical pores 315, and the first lower polygonal shaft hole 54 that one of apical pore 315 corresponds to the first bull wheel 50 (is such as schemed
Shown in 10)；As shown in fig. 9 again, the first bull wheel 50 has round plate 52 and one first lower circle on a first shaft portion 51, one first
Pan portion 53, the first upper and lower round plate 52,53 are separately connected the top of first shaft portion 51, bottom both ends, and the second bull wheel 60 has one the
Round plate 62 and one second lower disc portion 63 in two axle portions 61, one second, the second upper and lower round plate 62,63 are separately connected second
Top, the bottom both ends of axle portion 61, moreover, on the first of the first bull wheel 50 round plate 52 and the second bull wheel 60 second on disk
One is kept between the second lower disc portion 63 in the first lower disc portion 53 and the second bull wheel 60 of portion 62 and the first bull wheel 50
Preset distance.In addition, as shown in figure 11, the second shaft portion 61 of the second bull wheel 60 has one second lower polygonal shaft hole 64 (such as
Hexagon ring shown in Figure 13), the second lower polygonal shaft hole 64 corresponds to another apical pore of the second top plate 311 of bottom base 31
315.Be then in structure as the two lifting and drivings rope 34 it is identical as previous embodiment, hold do not repeat herein.
A second driving shaft 42 is more provided other than the first transmission shaft 40, in the present embodiment, second driving shaft 42 breaks
Face shape is hexagon.Second bottom outlet 215 and card of second bottom plate 312 of the top drawing-in top base 21 of second driving shaft 42
It is connected on the second of the second wind spring gear 23 in polygonal shaft hole 25 (as shown in FIG. 11 and 12), the bottom end of second driving shaft 42
Second apical pore 315 of the second top plate 311 of drawing-in bottom base 31 and the second lower polygon shaft for being connected in the second bull wheel 60
In hole 64 (as shown in Figure 11 and Figure 13), due to being the relationship of polygonal section between three, so that the second wind spring gear 23
It can be rotated synchronously by second driving shaft 42 with the second bull wheel 60.
By above structure it is found that when the two lifting and drivings rope 34 is stretched outward and gradually deviates from the first, second bull wheel
50,60 when, the first, second bull wheel 50,60 can rotate synchronously, and the first bull wheel 50 therein can be driven by the first transmission shaft 40
Dynamic first wind spring gear 22 can drive the second wind spring gear 23 by second driving shaft 50 as the second bull wheel 60, at this time
Wind spring 26 can be pulled by the first, second wind spring gear 22,23 to accumulate elastic-restoring force.Once two lifting and drivings rope, 34 institute
When the pulling force being subject to releases, the elastic-restoring force of wind spring 26 can act on the first, second wind spring gear 22,23, make first, second
Wind spring gear 22,23 rotates synchronously, and the first wind spring gear 22 therein can drive the first bull wheel 50 by the first transmission shaft 40,
It is then the second bull wheel 60 to be driven by second driving shaft 42, and then make the first, second bull wheel as the second wind spring gear 23
50,60 the lifting and driving rope 34 being matched therewith is furled respectively.
To sum up institute is old, and two-layer equation ropewinder 10,12 of the invention is by the way of upper push-down stack by driving unit 20 and volume
Rope unit 30 fits together, and achievees the effect that power transmission using at least one transmission shaft, can so not influence
Shorten whole length under the case where being driven effect, and then realizes the effect of miniaturization.
