Description

Infrared remote-controlled curtain opening and closing machine

The utility model relates to a kind of formula curtain that hangs from above and opens a device.

Present existing window curtain driving mechanism kind is many, though function is different, mostly based on traditional Wound-rotor type transmission.Occur faults such as rope yarn rubs, gets loose, clamping stagnation in the use easily, service life is short, and switch is dumb.

The purpose of this utility model is to provide a kind of fault few, dependable performance, window curtain driving mechanism easy to use.

In order to achieve the above object, the utility model has adopted a kind of brand-new kind of drive: flexible toothed belt---the horizontal transmission of slide block type.This window curtain driving mechanism comprises support, preceding slide bar, back slide bar, motor etc., above slide bar, be provided with four axle I～IV that are parallel to each other, also be provided with two cingulums parallel with slide bar, on the axle I driving wheel and a travelling gear are housed, one end of right cingulum and the engagement of this travelling gear, form one group of gear band transmission on the travelling gear of the other end on the axle III, on the axle III tumbler gear is housed also, this tumbler gear is meshed with another tumbler gear on being contained in an II, on the axle II travelling gear is housed also, left cingulum and this travelling gear and another travelling gear that is contained on the IV are formed another group gear Toothed Belts Gearing.In the groove of two slide blocks before and after the shifting block that a projection is respectively arranged below the cingulum of the left and right sides, this two shifting block are stuck in and are enclosed within on the slide bar.Because the effect of tumbler gear is rotated as long as drive, two cingulums are promptly done oppositely or move toward one another, thereby two slide blocks on the slide bar are done oppositely or move toward one another, drive the curtain that hangs from above on slide bar then and finish the action that opens or closes.

Above-mentioned gear Toothed Belts Gearing also can be the chain transmission.

Based on above-mentioned design, the utility model can also adopt another kind of structure, be about to that four above-mentioned travelling gears are corresponding to change four sheaves into, with two two cingulums that the corresponding replacement of rope is above-mentioned, the two ends of a rope are twined respectively and two ends are separately fixed on two sheaves that twined, thereby form the transmission of one group of rope sheave.The structure of another group rope sheave transmission is identical therewith.Will the rope that moves between two sheaves link to each other with slide block on being enclosed within slide bar or directly and the Curtain ring on the slide bar link to each other, when sheave rotates, drives around thereon rope and move, thereby the drive curtain moves, and has promptly realized the switch motion of curtain.

This window curtain driving mechanism has simple in structure, reliable transmission, and stable working, long service life, advantage such as cost is low, the curtain that can be widely used in public, civil buildings, car and boat opens and closes.

Fig. 1 is the structural representation of a kind of infrared remote control window curtain driving mechanism of the utility model.

Fig. 2 is an A-A cutaway view of the present utility model.

Below in conjunction with accompanying drawing the utility model is further described.

As shown in FIG., 1,1 ', 6,6 ' for being contained in four travelling gears on an IV, II, I, the III respectively, 3,4 is a pair of intermeshing tumbler gear, 2 is left cingulum, and 5 is right cingulum, 7 ' for driven wheel be worm gear, 7 is worm screw, and 8 is micromachine, and 9 is the remote control circuit plate, 10 is support, and 11 is left shifting block, and 12 is left slider, 13 is preceding slide bar, 14 is the back slide bar, and 15 is right shifting block, and 16 is right slide block.

Embodiment among the figure be with driving wheel 7 ' and travelling gear 6 made one, in addition, tumbler gear 4 and travelling gear 1 ', tumbler gear 3 and travelling gear 6 ' made respectively one.

Operation principle as embodiment among the figure is: when receiver is received the infrared signal that transmitter sends, remote control circuit plate control micromachine driving worm screw 7 is cooked regularly and rotates counterclockwise, driven wheel 7 ' clockwise rotate then, realized the one-level deceleration, clockwise rotate thereby make travelling gear 6 drive right cingulum 5, make shifting block 15 under the cingulum 5 stir slide block 16 and on slide bar 14, be moved to the left; Simultaneously, tumbler gear 3 and tumbler gear 4 engagements with travelling gear 6 ' connection mutually, travelling gear 1 ' drive cingulum 2 is rotated counterclockwise, shifting block 11 below the cingulum 2 is stirred slide block 12 and is moved right on slide bar 13, two slide blocks are done move toward one another respectively on two slide bars, once close the curtain action thereby draw a curtain to finish.

When next infrared signal was sent, remote control circuit control motor was done regularly and is clockwise rotated, and at this moment two slide blocks are done opposing motion, thereby finished the curtain action of windowing.

The also available hand switch of the utility model replaces infrared remote control.

Because driving member of the present utility model is stressed less, so all available plastics of travelling gear, tumbler gear and driven wheel or worm and gear or bakelite are made, can certainly make with metal material; Cingulum can be made with flexiplast or rubber, if make chain, can certainly adopt metal material; Support can be with aluminium section bar or is moulded firmly or the thin metal blank punching press is made, with weight reduction.
