The specific embodiment

Fig. 1 gives and have been shown a grown form of the present utility model and embodiment, and entire mechanism all is arranged in the end of grooved track, or is installed in the pedestal 10, and this pedestal is installed in the end of grooved in putting the beams in place, and then being connected of realization and Power Component.Be described in detail as follows referring now to each accompanying drawing.

The utility model is provided with Power Component at an end of upper beam or track, adopt that the (see figure 4) Power Component comprises CD-ROM drive motor 20 and power transmission shaft 24 thereof when electronic, adopt that (seeing Fig. 2,3) Power Component comprises the power transmission shaft 24 that manually furls bar 23 or drawing cable pulley 22 and manually furl boom end or drawing cable pulley axle head when manual.During motor-driven, the CD-ROM drive motor power transmission shaft enters in the pedestal 10 and meshes with driven wheel 30, and gear shaft is installed on the base wall by axle sleeve; During manual drives, manually furl the helical tooth of bar 23 ends or worm power transmission shaft and also enter in the pedestal and and be meshed with driven wheel.Wherein, manually furl bar and can be the short break-in bar that differs, is movably hinged mutually of several segment lengths.

From Fig. 1～4 as can be known, on gear shaft, also be fixed with driving-disc 31, radially evenly be provided with the through hole that is positioned on the same circular arc---drive hole 32 on the card of driving-disc.The axle core in the driving-disc outside is provided with along long line and furls dish 50, furl dish and be provided with through hole---fixing hole corresponding with drive hole and coupling, in fixing hole, be inserted with two ends trip(ping) lever 51 outside regularly, furling simultaneously disk axis is provided with slip pore 52 and this pore and is positioned at and furls the projection that a side that dish deviates from driving-disc promptly furls dish and be the T font, one perpendicular hollow and perforation of T word, the terminal outer wall of pore is provided with fixed block 53, be with the helical spring 54 that resets on the outer wall of pore, one of this back-moving spring is support with the fixed block, the other end is pressed on the outer wall of pedestal (produce one make furl " reset force " that dish and driving-disc are separated from each other), between trip(ping) lever and drive hole for movingly or matched in clearance.In furling the slip pore of dish, be provided with and allow an end that furls the connecting rod 61 that dish slides thereon, the other end of connecting rod stretch into to be arranged in track to cooperate the blade that drives sun blind behind other parts to finish lifting action.

In pedestal, driven wheel also meshes with the tooth sector 40 that axis is parallel to each other with it, and one section anodontia breach 41 is arranged on tooth sector.Tooth sector is coaxial with switch plate 42, this common axis also is arranged on the gear locular wall by axle sleeve, switch plate staggers mutually with the position that furls dish during installation, it is overlapped that switch plate is positioned at the outside and two plate edges that furl dish, simultaneously switch plate with furl dish card surface in opposite directions and be disposed radially an arcuation projection 43, the projection on this switch plate and surface thereof with furl dish, back-moving spring, connecting rod etc. and cooperate and constituted one and overlap arrangement of clutch; In addition, be provided with one with the spacing pin 44 of trip(ping) lever with the relative dish perisporium of the same diameter of arcuation projection, on the sidewall of pedestal, also be provided with one with trip(ping) lever mutually mapping with the supporting gag lever post 14 of pin, importantly the anodontia breach on projection on the switch plate and the tooth sector is in the same plane.After the tooth sector shaft extension goes out pedestal, by realizing angle adjustment with the blade that cooperating of other parts drives sun blind.So far, basic comprising of the present utility model is described.

Because electronic and manually identical on effect, so be that example operates explanation with electronic.

Drive driven wheel 30 by power transmission shaft 24 during CD-ROM drive motor 20 runnings and rotate, make louver lamina generation revolving force and control blade steering thereby driven wheel makes tooth sector 40 rotate thereupon; When tooth sector is subjected to driving to turn to gap position, projection 43 on the switch plate 42 also turns to and furls dish 50 overlappings, this projection has been carried out crowded pushing away to furling dish, order furls dribbling and trip(ping) lever 51 and be inserted in the drive hole 32 to driving-disc 31 motion and trip(ping) lever, this moment tooth sector because of the breach position with the driven wheel engagement and stopped operating by the restriction of pin 44 and gag lever post 14.At this moment, the power output of driven wheel has been transferred to and has furled on the dish, furls be dynamically connected bar 61 of dribbling and rotates, and this connecting rod drives louver lamina and realizes oscilaltion.

The foregoing description is that example is illustrated with sun blind, demonstrates fully mentality of designing of the present utility model, and this mentality of designing may extend to the transmission and the control device of traditional coiled curtain certainly.Therefore, which kind of curtain form no matter the utility model be applied to, and all can solve the problem that the utility model proposes, and realizes the purpose of the utility model.
