Above-mentioned each member and the composition mode thereof that is the utility model one control structure that preferred embodiment provides (100), now is described below it again as flowing mode:

Aspect amplitude adjustment control (the control blade rises or descends):

At first, when desiring to fold curtain blade (5), choose this actuation means of control (30) rotation by the user, and drive this force piece (21), worm screw (22), worm gear (23) and axostylus axostyle (25) rotate, make this amplitude modulation wheel (12) can by and this axostylus axostyle (25) between closely connect and rotate simultaneously, and with affixed amplitude modulation stay cord (6) rolling in last, and this amplitude modulation stay cord (6) (as shown in Figure 5) when being subjected to rolling, be wound in earlier on the conical surface of this tapering (124), entirely slip into gradually again on this afterbody (125), so just, can be by the rolling of this amplitude modulation stay cord (6) with this time rail (4) pull-up, and then by this time rail (4) each blade (5) is folded in regular turn, to reach the adjustment of control curtain blade (5) lifting height.

At this moment, because between this amplitude modulation wheel (12) and this FM Wheel (14), it is the state that is interlock by the binding of this moving part (154), therefore when this amplitude modulation wheel (12) initial rotation, can drive this FM Wheel (14) rotation earlier, make by this frequency modulation and turn round the action that rope (7) affects this each blade (5) work to incline and put, and rotate to a inclined-plane (153b) with this moving part (154) and this block (153) when contacting (as Fig. 6 and shown in Figure 8) when this FM Wheel (14), this moving part (154) just can be taken advantage of a situation along this inclined-plane (153b) and be moved in the shrinkage pool (151b) of this supporting seat (151), and push this spring (152) generation simultaneously and be out of shape, make this moving part (154) just can be subjected to the restriction of this inclined-plane (153b), and in the groove (143) of this FM Wheel (14), deviate from gradually (as shown in Figure 7), make just to present between this amplitude modulation wheel (12) and this FM Wheel (14) and separate and the different state that moves; Therefore this FM Wheel (14) just no longer is subjected to the drive of this amplitude modulation wheel (12) and adjusts the pivot angle degree that inclines of this blade (5), makes that this amplitude modulation wheel (12) is sustainable to be batched this amplitude modulation stay cord (6) and fold blade (5).

Now, when desire is opened the blade (5) of (stretching, extension) curtain, control this actuation means by the user and carry out in the other direction (direction when folding blade is opposite) rotation, making can be by the rotation of this force piece (21), worm screw (22), worm gear (23) and axostylus axostyle (25), and be with this amplitude modulation wheel (12) to rotate, making the amplitude modulation of rolling originally on this amplitude modulation wheel (12) turn round rope (6) just can be loosened gradually and transferred, make this time rail (4) and blade (5) just can be subjected to interlock and move down, so that each blade (5) presents the state of unlatching; When amplitude modulation wheel (12) initial rotation the time, this FM Wheel (14) still be subjected to this block (153) inclined-plane (153b) effect and with this amplitude modulation wheel (12) between present and separate different moving, when the moving part (154) in this amplitude modulation wheel (12) groove (126) is driven by amplitude modulation wheel (12) and during groove (143) corresponding position in this FM Wheel (14), just can be subjected to the elastic force of this spring (152) and be pushed in this groove (143) in, make this FM Wheel (14) and this amplitude modulation wheel (12), just be by the binding of this moving part (154) once again again with moving, therefore be subjected to the drive of this amplitude modulation wheel (12) and when contacting on another inclined-plane (153c) of this block (153) (as shown in Figure 9) when this moving part (154), just can be subjected to the obstruct on this inclined-plane (153c) once again and break away from this FM Wheel (14), make this each blade (5) pendulum that just no longer inclines, and only unclasp this amplitude modulation stay cord (6) to reach the effect of opening this each blade (5) with this amplitude modulation wheel (12).

Be right after work, aspect control frequency modulation (promptly controlling blade lean):

At first, controlling this actuation means (30) by the user is rotated, impel this amplitude modulation wheel (12) to rotate, and by the binding of this moving part (154) with this FM Wheel (14), and make this FM Wheel (14) and this amplitude modulation wheel (12) moving together, and then furl this frequency modulation stay cord (7) to control the pivot angle degree that inclines of this each blade (5), and because the pivot angle degree that inclines of each blade (5) does not need big wide, so in design, this FM Wheel (14) only is that with scope that this amplitude modulation wheel (12) rotates synchronously this supporting seat (151) periphery is not provided with the position angle interior (being about 180 degree) of block (153); And put to suitable position when this each blade (5) inclines, can stop the rotation of this actuation means (30), enable to reach and adjust blade (5) and incline the effect of pivot angle degree (in the above-mentioned operation, since this amplitude modulation wheel (12) because of turn round in the rotation a little or the amount of height of this time rail (4) that descends minimum, also unlikely influential for the reliability of operation).

Above-mentionedly be control structure (100) each member and mode of occupation thereof that the utility model first preferred embodiment is provided, now makes brief of the introduction advantage of the present utility model as follows again:

Because the utility model utilizes actuation means (body of rod) to control the lifting of curtain blade and the pendulum that inclines, therefore there is no the stay cord that exposes and exist, and can avoid the child and expose the danger situation of tangling between stay cord.

Moreover, because the utility model can be by same control member (actuation means), respectively curtain blade is done the adjustment at lifting and angle of inclination, therefore not only can make control comparatively simple and easy (single operation source), the member that curtain is exposed reduces (can save using the frequency modulation bar that exposes always), make in appearance more simplicity generosity, should go up in the rail simultaneously and can save the separate type fm mechanism of commonly using, therefore after the shared horizontal space of former separate type fm mechanism is save, can make that last rail of the present utility model is more exquisite small and exquisite.

In addition, for avoiding curtain blade when rising folds, have because of its weight is gone am component and fm components in vain and rotate the anxiety that blade is descended voluntarily, this linkage also is a self-locking device, can when not controlled by this actuation means, can locate really to limit this linkage, also can drive worm gear by worm screw rotates, and can't rotate (so worm and gear is originally as a force multiplication system) by this worm screw of worm gear drives, certainly the utility model is extremely heavily following in the weight of blade assembly, when the self-locking effect of this worm and gear is not enough, also can add a self-locking device, this self-locking device must can be with the restriction cancellation of self-locking device by user's control, carry out the lifting of curtain and the control of the pendulum that inclines, to increase the safety of curtain, and because this self-locking device has been the member that the market is used always, therefore in the utility model, just do not given unnecessary details.
