Abstract
A roller blind used automatic sunshade cloth uncoiling mechanism is characterized in that the utility model consists of a sunshade cloth coiling/uncoiling gear fixed on a roller blind frame, and a sunshade cloth uncoiling actuating unit connected with the sunshade cloth coiling/uncoiling gear. The sunshade cloth uncoiling actuating unit consists of a shaft connected with the roller blind frame, lead screws arranged on the shaft ends, covers arranged on the lead screws through threads, springs arranged on the shaft and hooks connected with free ends of the springs. Fixed ends of the springs are fixed on the shaft ends. Fasteners are arranged at the positions on the covers corresponding to the hooks; the covers are connected with a sunshade cloth spool. Compared with prior art, the utility model has the advantages that when part of the roller blind is uncoiled automatically, the roller blind can uncoil the sunshade cloth coiled on the sunshade cloth spool automatically.
Description
Technical field:
The utility model relates to a kind of curtain accessory.
Background technology.
The automatic fallen curtain of existing casement, when needs are accepted casement, its casement be with folding mode be collected in curtain rod arm below, such collection mode is because therefore the weight of casement all concentrates on the stay cord,, need many stay cords to spur casement simultaneously, and the action of stay cord must be synchronous, so that casement folding and unfolding simultaneously successfully.This kind curtain is in case wherein stay cord disconnection will influence the normal folding and unfolding of casement, and exposed folding casement is also hidden dirt easily.In order to address the above problem, people adopt the mode of roller shutter to come automatically casement to be put down, but, because casement is to be wound on the casement reel of roller shutter, when beginning to put casement, because the casement that is wound on the casement reel does not have downward power, need artificial elder generation that roller shutter is put down a part, so that the casement that part of casement that puts down utilizes the gravity of himself will be wound on the casement reel pulls down.Though this kind curtain has solved the shortcoming of folding and retraction curtain, because when putting curtain, need manually earlier roller shutter is put down a part, therefore, it is very inconvenient to operate.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of and need not wants artificial elder generation roller shutter to be put down a part, the automatic opening mechanism of roller shutter that roller shutter just can put down the casement that is wound on the casement reel automatically.
The utility model is to realize like this, discharging actuating unit by the roller shutter cloth that is fixed on casement rolling/relieving mechanism on the roller shutter frame, link together with casement rolling/relieving mechanism constitutes, roller shutter cloth discharge actuating unit by the axle, the screw mandrel that is arranged on axle head that link together with the roller shutter frame, the hook that is threaded in cover on the screw mandrel, is arranged on spring on the axle, link together with spring free end constitutes, the fixed end of spring is fixed on the axle head, put facing to the hook place and be provided with button, cover links together with the casement reel.During work, do the action of rolling roller shutter cloth by the casement rolling/relieving mechanism drive casement reel that is fixed on the roller shutter frame, along with the rotation of casement reel, the cover that links together with it is also along with rotation, and move toward the hook direction along screw mandrel, when rolling roller shutter cloth finished soon, cover also moved to the hook place, makes hook hook buckling of cover, hook also rotates, along with the end of rolling roller shutter cloth, spring has also been saved certain screen resilience under the drive of hook; When needing to be wound on roller shutter cloth on the casement reel and discharging, touch casement rolling/relieving mechanism, make the casement reel be in free rotary state, at this moment, under the effect of the screen resilience of spring, hook discharges the rotation of roller shutter cloth by the moving interplanting of cingulum, a part of roller shutter cloth is discharged from the casement reel, simultaneously, cover leaves hook, cover and hook is no longer interacted, at this moment, because part roller shutter cloth discharges from the casement reel and forms enough gravity, under the pulling of roller shutter cloth gravity, roller shutter cloth constantly discharges from the casement reel so in this section, until touching casement rolling/relieving mechanism again, make the casement reel no longer be in free rotary state, will be wound on the action that the casement on the casement reel puts down thereby finish automatically.
Here, axle is provided with change, and the hook of convex is arranged in the change, and that end that puts facing to change is provided with the hole that matches with change, and the button of convex is arranged in the hole.Hook has guaranteed that by the overlap joint of the button in change and the trepanning hook can fasten and be not easy to throw off.
The utility model compared with the prior art, owing to utilized screen resilience that spring saved initial driving force when discharging roller shutter cloth when the rolling of roller shutter cloth, therefore, have and to want artificial elder generation roller shutter to be put down a part, the advantage that roller shutter just can put down the casement that is wound on the casement reel automatically.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model is by the casement rolling/relieving mechanism 2 that is fixed on the roller shutter frame 1, the roller shutter cloth that links together with casement rolling/relieving mechanism 2 discharges actuating unit 3 formations, roller shutter cloth discharges actuating unit 3 by the axle 3a that links together with roller shutter frame 1, be arranged on a screw mandrel 3b of 3a end, be threaded in the cover 3c on the screw mandrel 3b, be arranged on the spring 3d on the 3a, the hook 3e1 that links together with spring 3d free end, the fixed end of spring 3d is fixed on the 3a end, cover 3c goes up facing to hook 3e1 place and is provided with button 3c2, and cover 3c and casement reel 4 link together.
Axle 3a is provided with change 3e, and the hook 3e1 of convex is arranged on the change 3e1, and that end that cover 3c goes up facing to change 3e is provided with the hole 3c1 that matches with change 3e, and the button 3c2 of convex is arranged in the 3c1 of hole.
Cover 3c is provided with mosaic groove 3c3, and the casement reel 4 of corresponding mosaic groove sheet 3c3 is provided with inlays guide rail 4a, cover 3c by mosaic groove 3c3, inlay guide rail 4a and be positioned on the casement reel 4, cover 3c can only be moved axially along casement reel 4.The inlaying guide rail 4a and can exchange of the cover mosaic groove 3c3 of 3c and casement reel 4.Casement rolling/relieving mechanism 2 is made of rotating mechanism 2a, clutch 2b, and rotating mechanism 2a links to each other with casement reel 4 by clutch 2b.During use, in the time of roller shutter cloth need being twisted on the casement reel 4, clutch 2b is closed, drive casement reel 4 and rotate by rotating rotating mechanism 2a then, roller shutter cloth is twisted on the casement reel 4, need be when casement reel 4 puts down with roller shutter cloth, clutch 2b is separated, make casement reel 4 be in free state, like this, roller shutter cloth utilizes the gravity of himself to put down from casement reel 4.
