Abstract

The utility model relates to an operating device for the electric open and close of shielding decorative articles, such as curtains, antependia, screens, etc. The utility model is characterized in that a curtain-operating gear rack is inserted into a tank-shaped window rail; the curtain-operating gear rack is directly driven and shifted by a gear which is connected with a motor to realize the open and the close of the curtains and the antependia. Compared with the prior art, the utility model has the advantages of simple structure, balanced and reliable running, good synchronization and large load for pulling the curtains, and is suitable for the open and the close of overweight curtains and antependia. The utility model uses the flexible gear rack, and can also used for the open and the close of cambered curtains and antependia.

Description

Electric curtain-operating device

Utility model is the drive unit that blocks the electronic folding of jewelry about curtain, valance etc.

Known electronic driving in the curtain device, a kind of is to affect assembly pulley by drive motors, thereby drives curtain, curtain folding, as Chinese patent 86200328,87208745,88209204 etc.; A kind of is that the motor-driven screw mandrel rotates, thereby the slide block that cooperates with wire rod thread is moved, and pulling curtain, curtain folding are as Chinese patent 92202506,92212204.Yet these the two kinds electronic curtain devices that drive, structure is more complicated all, and needs by middle transmission, and parts are many, processing and manufacturing cost height, assembling is complicated.The former pulling force is little, and pulley easily takes place in permanent use skids, poor reliability, and double width curtain, curtain folding are difficult for influencing the folding effect synchronously; Though the latter has synchronism preferably, long filament bar processing cost height, but also need join curtain, curtain guide rail in addition, folding speed is slow.In addition, the above-mentioned electronic curtain device that drives all can not drive arc curtain, curtain, and therefore still having is worth improved place.

The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of structure more simple, and cost is low, uses reliably, and drawing power is big, can really realize the electronic curtain device that drives that directly drives.

Another purpose of utility model is to provide a kind of electronic curtain device that drives that can also drive arc curtain, curtain.

For realizing above-mentioned main purpose, utility model adopts motor driven gear directly to drive and draws (pushing away) curtain tooth bar, to realize the folding of curtain, curtain.Specifically, the electronic curtain device that drives of utility model comprises drive motors and parallel window rail, it is characterized in that said window rail is a grooved rail, the tooth bar that movably drives curtain, curtain folding is arranged in the groove, and said motor is connected with a driven wheel, said driven wheel and rack tooth engagement.When motor rotated, two tooth bars drove curtain, curtain folding in the gear drive subinverse in the parallel window rail groove to moving back and forth.

The said grooved window rail of utility model is mainly and draws (pushing away) curtain tooth bar to move guide-localization is provided, and it can be with the L shaped of a side and a base or have the U-shaped, rectangle, ellipse etc. on dual-side and base at least, make the back side of tooth bar and bottom surface that one holder retaining be arranged.Establish curtain, curtain guide rail in addition for omitting, the preferred grooved window rail of utility model is U-shaped, rectangle or the ellipse that has dual-side and base at least, gear, tooth bar engagement place at two relative inner side edges cut out one, so that engaged transmission, have curtain on the base, curtain moves groove.

Another purpose of utility model realizes, to be the tooth bar that will drive curtain, curtain make with plastics or similar material can crooked flexible rack, and flexible rack is put into the window rail that is convexly curved, and can realize the folding of arc curtain, curtain.Certainly straight type curtain, curtain also can use flexible rack.

Below in conjunction with several preferred embodiments, further specify utility model.

Fig. 1 is a double width individual layer curtain driving device structure schematic diagram.

Fig. 2 is a double width double-layer window curtain driving device structure schematic diagram.

Fig. 3 is a double width individual layer arc curtain driving device structure schematic diagram.

Fig. 4 is that Figure 1A-A is to cutaway view.

Embodiment 1: referring to Fig. 1, on curtain rod arm 1, be fixed with alternate two parallel U-shapeds or rectangle curtain grooved rail 2a, 2b, have opening groove 4a, 4b in the grooved rail bottom, this open slot ditch effect is moved for hanging the curtain drag hook or pressing from both sides folding, establish Curtain rail in addition to omit, be interspersed with plastics tooth bar 3a, the 3b of length in the curtain grooved rail respectively greater than 1/2 window rail.The back side, curtain rod arm middle part is fixed with and exchanges reversible electric machine (not providing among the figure), is fixed with driven wheel 5 on the output shaft.Two grooved rails have all dug a breach 6a, 6b at the two relative inner side edges at driven wheel place, so that the engagement of wheel and rack tooth.Two tooth bar outer ends respectively are fixed with one and draw the curtain hook or press from both sides 7, make tooth bar draw, promote closing, opening of curtain in, reciprocating cutter.Tooth bar operation two-end-point place is equipped with return of stroke switch 8a, 8b, ends and commutation with the control stroke.For reduce tooth bar slide in the friction of window rail, arc is processed at the tooth bar back side, or in the side and/or alternate ball or the miniature bearing (not providing among the figure) of being embedded with in bottom surface.

Embodiment 2: referring to Fig. 2, as embodiment 1, be fixed with 2 pairs of parallel window rails on the curtain rod arm, with 2 motors, 2 pairs of tooth bars of gear drive, to realize the double-layer window curtain folding.

Embodiment 3: referring to Fig. 3, and embodiment as described above, curtain rod arm and the grooved window rail two ends of fixing on it are curved, are interspersed with the plastics flexible rack in the window rail groove, and tooth bar is crooked according to window rail in moving process like this, can drive the opening and closing of arc curtain.

Utility model is electronic drives in the curtain device, also can install press button and remote control additional in addition, to realize the optional position folding and the remote control folding of curtain.The tooth bar two ends also can add stay cord realization power failure and manually draw curtain.

Utility model is owing to adopting gear, the direct transmission of tooth bar to draw curtain, and is simple in structure than prior art, making, easy for installation, and cost is low, and it is reliable to operate steadily, and synchronism is good, and folding speed is fast, draws curtain load big, can be used for the folding of overweight curtain, curtain.Use flexible rack also to can be used for the folding of arc curtain, curtain.Utility model not only can be used for curtain, also can be used for other blocks jewelry as stage curtain, cloth screen, figure curtain etc. folding.
