In this, when desire up spurs curtain blade (desire originally the position of blade up during pull-up one predetermined altitude), just should control down drawing of rope (22) earlier by the user, this moment is because an end of this control rope (22) is to be fixed on this bull wheel (21), and controlled rope making (22) circle around stressed member (312) axle center position in the oblique below of this bull wheel (21), therefore when control restrict (22) be subjected to external force that the user executes down during drawing, just can suffered downforce be conducted on this stressed member (312) by this control rope (22), making this stressed member (312) this beat spare of interlock (311) beginning is that the axle center is toward below pivot pendulum with this trace (32), this stressed member this moment (312) just drives this trace (32) and rotates in the same way, make the just pivot pendulum and lean portion (123) cell wall (as shown in figure 10) of pulling that supports up of limiting section (322) that is positioned at this round bar (321) opposite side to this main lid (12), this trace (32) just is obstructed and no longer rotation this moment, and only make this control rope (22) continue down drawing by the external force that the user executed, the service portion (323) that be positioned at this limiting section (322) homonymy this moment also can be simultaneously pivot pendulum up, make by this service portion (323) the impedance part (333) of this clamping piece (331) contact pivot pendulum and this pre-power spring (34) compressed up, make the claw (332) of this clamping piece (331) understand down pivot pendulum, and form the state (as shown in Figure 8) that breaks away from the ratchet of this blocking wheel (23), and this one is subjected to this control rope (22) institute's drawing and the bull wheel (21) that rotates simultaneously, also begin to drive rotation in the same way by friction by the outer surface of this socket section (216) and the inner surface of this unidirectional fastening spring (241), make unidirectional fastening spring (241) that this direction rotation can be tightened internal diameter just can begin to be clamped in the stopper section (235) of this socket section (216) and this blocking wheel (23), this bull wheel (21) and this blocking wheel (23) just can be by the clamping action of this unidirectional fastening spring (241) with moving state, and connecting rod (B) driven rotary that will be moving together with this blocking wheel (23) makes and the blade of this curtain up can be folded.
So, when desire will rise to the blade location in precalculated position, then only need to control rope (22) and slightly unclasp a bit of length, make this pre-power spring (34) by compression the back stretch that produced of back restrict (22) down during the external force of drawing greater than executing in this control, this pre-power spring (34) just can be pushed the impedance part (333) of this clamping piece (331), make the position understand up pivot pendulum at the claw (332) of this impedance part (333) opposite side, and with the ratchet engagement (as shown in Figure 7) of this blocking wheel (23), make just can't go again this blocking wheel (23) at this moment and rotate and locate, cause the connecting rod (B) that is subjected to this blocking wheel (23) institute interlock and blade just to form the state of locating this moment simultaneously.
Now, because at this control rope (22) down during drawing, the positioning section (214) of this bull wheel (21) also can be simultaneously with involution unit (40) the one end rotary tightenings that set firmly thereon, cause this involution unit (40) deflation and produce a pre-power (as shown in Figure 6) that unclasps, therefore as user during with control rope (22) relieving that originally is gripped in the hand, this involution unit (40) just can be because of the not stressed state that returns back to that pins down of no external force (power that the user executed), make this bull wheel (21) just can be subjected to the drive of this involution unit (40) and be rotated (as shown in Figure 5) (rotation direction of this rotation direction during with drop-down control rope is opposite), enabling to control rope (22) furls and is wound on this bull wheel (21), and only be exposed at outward outside this bull wheel (21) by its vertical piece and do not have the doubt that control rope (22) exposes, to reduce the danger of tangling strangulation.In addition, in this special instruction, because this unidirectional fastening spring (241) only can clamp in single rotation direction, and this rotation direction is identical with the rotation direction that this bull wheel (21) discharges this control rope (22), so the rotation direction of this bull wheel (21) when furling this control rope (22), can't tighten this unidirectional fastening spring (241), so just can make this blocking wheel (23) not be subjected to the same moving of this bull wheel (21), make when furling control rope (22) and can't the height of curtain blade be exerted an influence.
Outstanding again, when desire is done the reduction of an appropriateness height with this curtain blade, to control rope (22) work one (a bit of length) drop-down slightly this moment earlier, and this drop-down distance is extremely short, can't make this unidirectional fastening spring (241) clamp this blocking wheel (23), promptly meaning this bull wheel (21) is non-being with moving state with this blocking wheel (23) at this moment, therefore restrict (22) slightly down during drawing when this control, also can make this beat spare (311) work one beat and then this service portion of interlock (323) push against this impedance part (333) and compress this pre-power spring (34), and the claw (332) of this clamping piece (331) and the ratchet of this blocking wheel (23) are broken away from, just can drive this blocking wheel (23) rotation this moment by the weight of blade itself and then blade is dropped to predetermined height; And when height that desire stops blade being positioned to be scheduled to, just the external force that will bestow control rope (22) is eliminated (promptly unclasping this control rope (22)), this pre-power spring (34) is replied once again, and with the claw (332) of this clamping piece (331) once again with this blocking wheel (23) bridle joint, make this blocking wheel (23) can't go rotation again, so just can be with the location of this appropriateness of this blades height.
Thus, control structure provided by the utility model, can not only be controlled the highly control interface of ascending, descending of blade (shield assemblies) by the single control rope conduct of putting (non-loop) of hanging down, so that the user to be provided the most convenient, simply control mode, and increase user's property convenient for control; Again and, owing to this bright control rope also can by the pre-power of the answer of involution unit be carried out be collected in this bull wheel in, dive because of existing and there is the exposed danger of rope yarn (control rope), can make its security greatly increase.
In addition, specify that keeper in the present embodiment has can avoid the user will control the effect that this stressed member situation of rope disengaging takes place accidentally at drawing control rope at this.The limiting section of this trace then can by and this support the conflict pull between portion, and the special-effect that keeps this trace only can pivot to put a predetermined angular, to avoid up the pivot pivot angle to spend conference the compression spring is bestowed excessive pressure, or down the pivot pivot angle is spent greatly and then can easily be caused the damage of member to causing the strength of excessive clip between blocking wheel and clamping piece.
