And because the bumps (1121) of the inner cylinder (112) and the bumps (1131) of the outer cylinder (113) are separably engaged in the engaging grooves (151) of the front cap (15), respectively Between the inner and the engaging block (152), the winding wheel (111) is used to pull the cord (A) and the inner tube (112) is driven by the winding wheel (111), the outer tube (113) And the front cap (15) can be interlocked with the inner cylinder (112) to drive down the cord (A). Similarly, when the cord (A) is to be retracted, the winding wheel (111) is rotated counterclockwise, and the inner cylinder (112) is rotated counterclockwise by the extension piece (1111), which in turn drives Withdrawal of the cord (A).

When stopping using the take-up wheel (111) to pull the curtain (A), for example, rotating the take-up wheel (111) counterclockwise will retract the curtain (A), then retract the curtain (A) and release the curtain When winding the wheel (111), the outer cylinder (113) may cause the front cap (15) and the inner cylinder (112) to rotate clockwise due to the gravity of the cord (A). However, the inner cylinder (112) After rotating clockwise, the blocking portion (1122) of the inner cylinder (112) will push against the protruding portion (131) of the first elastic member (13), so that the first elastic member (13) is re-tightened The fixed base (16), the first elastic member (13) will not rotate relative to the fixed base (16), and the inner cylinder (112), the front cap (15) and the outer cylinder (113) cannot be Turning, the curtain (A) can therefore be positioned without falling down. This scenario is not depicted in the diagram, only described in text here.

Please refer to the fourteenth figure, and please match the second figure. After the solenoid valve (12) is energized, the solenoid valve (12) controls the shaft (141) to extend and push against the front cap (15), so that the front The cap (15) is separated from the inner cylinder (112) and the outer cylinder (113), the winding mechanism (11) is not resisted by the first elastic member (13), and the cord can be quickly lowered by gravity ( A), and the second elastic member (142) resists the retaining wall (161) and compresses and stores an elastic potential energy; after the solenoid valve (12) is powered off, due to the front cap (15) and the shaft The component (141) is fixedly connected by the screw component (143), and the second elastic component (142) releases the elastic potential energy and simultaneously drives the shaft component (141) to reset, thereby causing the front cap (15) to snap again Close to the inner tube (112) and the outer tube (113).

Please refer to the fifteenth and sixteenth figures, and please match the second figure. When the outer tube (21) rotates and hangs the curtain (A), the outer tube (21) drives the first slide (233) ) Along the limit bar (211) cooperates with the second threaded portion (2311) of the inner tube (231) and rotates on the inner tube (231) in the direction of the second slide (2321), when When the first slider (233) is pushed against the second slider (2321), the first coupling portion (2332) is coupled to the second coupling portion (2323), and the first slider (233) is received by the The second slide (2321) blocks and does not continue to rotate on the inner tube (231). Since the first slide (233) no longer rotates, the outer tube (21) will not rotate either, so the curtain (A) will not continue to fall and will be restricted.

Please refer to figures 16 to 18, when the first coupling part (2332) of the first slide (233) is coupled to the second coupling part (2323) on the second slide (2321) Afterwards, the first slide (233) will still drive the second slide (2321) to rotate due to inertia. At this time, one end of the buffer elastic member (2322) is driven and twisted by the second sliding seat (2321), but the other end is still fixed on the fixing portion (2312) of the inner tube (231), and the inner tube (231) It is restricted by the outer rod (22) without rotating and moving. The cushioning elastic member (2322) thus stores a cushioning spring potential energy, so that the second slider (2321) stops being rotated, and the first slider (233) After being restricted by the second slide (2321), the outer tube (21) stops rotating. In this way, the cushioning elastic member (2322) can slow down the impact force of the cord (A) when it is limited [the cord (A) please match the second picture], and indeed maintain the limit state to avoid the first sliding seat (233) Although it is blocked by the second slide (2321) and cannot continue to rotate on the inner tube (231), it still drives the second slide (2321) to rotate in place and cannot be surely limited. The cushioning elastic member (2322) prevents excessive impact force from damaging the limiting mechanism (23), or even the entire curtain of the fast-drop curtain. When the curtain (A) is stowed, the outer tube (21) drives the first slider (233) to cooperate with the second threaded portion (2311) of the inner tube (231) along the limit bar (211) Reverse rotation away from the second slider (2321), at this time the cushioning elastic member (2322) releases the cushioning spring potential energy to reset the second slider (2321), but this scenario is not depicted in the diagram Out.
