The specific embodiment
For clearer narration technical scheme of the present invention, below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, the arrangement of clutch of curtain driver comprises disengaging yoke 7, is socketed in the drop-down shift fork 8 in disengaging yoke 7, fork 9 is refuted in the locking being socketed in drop-down shift fork 8, fork 9 is refuted in locking can be in the interior any rotation of drop-down shift fork 8, be arranged on the torsion spring 10 on drop-down shift fork 8 and locking shift fork 9, wherein, disengaging yoke 7 is unilateral bearing tumbler, drop-down shift fork 8 can only only be done forward rotation in disengaging yoke 7, is used as while rotating backward, drop-down shift fork 8 drives disengaging yokes 7 to rotate together.Drop-down shift fork 8 is provided with drop-down shift fork angle 80, locking is refuted fork 9 and is provided with locking shift fork angle 90, torsion spring 10 is with left-handed torsion spring angle 10' and dextrorotation torsion spring angle 10'', left-handed torsion spring angle 10' can conflict with drop-down shift fork angle 80, when torsion spring 10 rotates backward, due to left-handed torsion spring angle 10' and drop-down shift fork angle 80, conflict and kill, left-handed torsion spring angle 10' drives drop-down shift fork angle 80 to rotate together.Dextrorotation torsion spring angle 10'' can conflict with locking shift fork angle 90.When torsion spring 10 forward rotation, because dextrorotation torsion spring angle 10'' conflicts and kills with locking shift fork angle 90, dextrorotation torsion spring angle 10'' drives locking shift fork angle 90 to rotate together.Power input shaft 6 is socketed in locking shift fork 9, and it can only forward rotation in locking shift fork 9, when its backwards rotation, drives to lock shift fork 9 and rotate together.
As shown in Figure 2, torsion spring 10 is made by rigid metal part or rigid plastic member, and torsion spring 10 is with left-handed torsion spring angle 10' and dextrorotation torsion spring angle 10''.
Shown in seeing figures.1.and.2, the left-handed torsion spring angle 10' of torsion spring 10 is stuck on locking shift fork 9 by the locking shift fork angle 90 of locking shift fork 9, the dextrorotation torsion spring angle 10'' of torsion spring 10 is stuck on drop-down shift fork 8 by drop-down shift fork angle 80, because the left-handed torsion spring angle 10' of torsion spring 10 is stuck on locking shift fork 9, locking shift fork 9 is one-directional rotation.When power input shaft 6 forward rotation, disengaging yoke 7, in the interior idle running of drop-down shift fork 8, loses the transmission of power; When power input shaft 6 rotates backward, power input shaft 6 drives 9 rotations of locking shift fork, conflict with the dextrorotation torsion spring angle 10'' of torsion spring 10 in locking shift fork angle 90 in locking shift fork 9, make torsion spring 10 be subject in one, compressing locking state under opposite force effect, thereby complete the locking of opposite force, curtain or weight can upper at an arbitrary position lockings.When curtain body promotes, power input shaft drives lifting device that curtain body is promoted.When curtain body declines, drive unit is connected with disengaging yoke 7 by driving key 70, and can drive disengaging yoke 7 rotations, and because disengaging yoke 7 is done positive movement 8 of drop-down shift forks, when playing counter motion, disengaging yoke 7 drives drop-down shift fork 8 to do counter motion.Meanwhile, because the drop-down shift fork angle of drop-down shift fork 8 can drive left-handed torsion spring angle 10' to counter-rotate, the locking of left-handed torsion spring angle 10' and drop-down shift fork 8 is disengaged, and under the effect of curtain body weight power, curtain body is transferred naturally.
Fig. 3 is the draw bail schematic diagram of disengaging yoke 7 and locking shift fork 9, as shown in Figure 3, disengaging yoke 7 comprises disengaging yoke 7 plastic parts 71 and disengaging yoke unilateral bearing 72, and described disengaging yoke 7 plastic parts 71 and disengaging yoke unilateral bearing 72 are integrally formed, and it can only one-directional rotation.Drop-down shift fork 7 comprises drop-down shift fork 7 plastic parts 71 and drop-down shift fork unilateral bearing 72, and described drop-down shift fork 7 plastic parts 71 and drop-down shift fork unilateral bearing 72 are integrally formed, and it can only one-directional rotation.Disengaging yoke 7 is comprised of plastic parts 70 and unilateral bearing 71, and locking shift fork 9 is comprised of plastic parts 90 and unilateral bearing 91.Wherein, described disengaging yoke 7 is with the one-directional rotation bearing arrangement that drives key 70, described drop-down shift fork 8 is the tube-in-tube structure with drop-down shift fork angle 80, described drop-down shift fork 8 is socketed in described separation and refutes in fork 7, described drop-down shift fork 8 is done forward rotation 7 of disengaging yokes, when rotating backward, disengaging yoke 7 drives drop-down shift fork 8 to rotate together.
Scope of the present invention is not subject to the restriction of described specific embodiments, and described embodiment, only as the single example of illustrating various aspects of the present invention, also comprises method and the component of functional equivalent in the scope of the invention.In fact, except content as herein described, those skilled in the art can easily grasp multiple improvement of the present invention with reference to description and accompanying drawing above.Within described improvement also falls into the scope of appended claims.Every piece of list of references mentioned above is listed in herein as a reference all in full.
