Abstract

The utility model relates to an electric opening and closing device with toothless screw-driven drawing for a curtain. At present, a pulling rope is served as the driving medium of drawing power, while the utility model adopts electromotion to drive a long axis to rotate, and drives two pairs of toothless screw-driven driving heads on the long axis to draw the curtain in relative or opposite direction to move along the axial direction to obtain the purpose of the free opening and closing of the curtain. The utility model can effectively avoid the shortages that the pulling rope is served as the drawing mode singly; the pulling rope has easy winding and blocking, inflexible drawing, etc; the utility model can realize remote operation; the utility model which has ingenious and practical structure time saving, labor saving can meet the ever growing demands of household decorating and comfortable degree of people at present.

Description

Electric device for drawing curtain

The utility model relates to a kind of practical daily necessities, the improvement of the manual tractive kind of drive of curtain open/close device.

Existing curtain open/close form, mostly be Curtain suspension device greatly on a cross bar, by the reciprocal connection traction folding of stay cord, because the cause of stay cord connected mode, tractive is dumb but also occur easily that stay cord is deviate from from race two or stuck, the defect that generation can't affect again.

The utility model is that a kind of exquisiteness, electronic anodontia worm drive traction curtain open/close device simple in structure handled will be provided.

The purpose of this utility model is achieved in that its long transverse lever with former extension curtain link, changes a rotatable major axis into; Major axis is positioned at by two movable pedestals on the sole of bottom belt length groove, and an end of the outstanding movable pedestal of major axis joins by coupling band and reduction box, and fixes by set screw, and the reduction box other end is connected with a motor; Be with two power transmission heads on the major axis, three eel-like figure rollers at a distance of equity are all arranged in the outer ring set of each driving head, arrange with same angle of inclination and opposite incline direction respectively, and just in time be pressed on the major axis.The eel-like figure roller is connected with the outer shroud cover by a sheet at two ends respectively, and there is a back-moving spring outer ring set lower end, and it can make outer ring set pack tightly to guarantee the certain pressure of eel-like figure pair of rollers major axis.The frictional force that this pressure produced can make the eel-like figure roller move vertically along with the rotation of major axis, and the outer ring set horizontal axis of drive moves; Outer ring set has a smooth block bottom, and it can make outer ring set not rotate with the rotation of major axis, and the Rod-shape hand apparatus for open and dose curtain that can drive the bottom moves horizontally in the elongated slot of sole.Also have several to have the follower rollers of curtain link on the sole, link also can move in elongated slot, and makes rotatablely moving of axle become axially moving horizontally of a last driving head.To there be the tooth transmission to change anodontia transmission into because of not needing much power to get final product, and then reach the purpose of draw-back curtain.

Owing to adopted the rotation of driven by motor major axis, and affected driving head to drive pull bar folding curtain, made this mode that affects become a kind of mode the most laborsaving, minimum trouble.It can also avoid easy winding of stay cord to take off groove and stuck phenomenon, can carry out remote-controlled operation simultaneously, brings great convenience in addition to the user, and its kind of drive also has much new meaning, is simple in structure, light and practical.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the front view that removes front portion sole side plate and the outer ring set of front driving head of the present utility model.

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

Fig. 3 is a B-B profile of the present utility model.

Fig. 4 is the vertical view of the sole of the utility model bottom belt length groove.

1. major axis among the figure; 2. movable pedestal; 3. the sole of bottom belt length groove; 4. coupling band; 5. reduction box; 6. set screw; 7. motor; 8. power transmission head; 9. outer ring set; 10. eel-like figure roller; 11. roller props up sheet; 12. smooth block; 13. Rod-shape hand apparatus for open and dose curtain; 14. follower rollers; 15. back-moving spring; 16. the elongated slot of sole upper bottom portion; 17. curtain link.

As Fig. 1--shown in 4, when needs were drawn the curtain apart, motor (7) drove major axis (1) and inwardly rotates thereupon, and drove three eel-like figure rollers (10) of pressing in the outer ring set (9) of right side transmission thereon, rolled " climbing " thereupon, and promptly level moves right; The pull bar (13) of its outer ring set (9) lower end drives curtain and draws back to the right; Because three the eel-like figure rollers (10) in the outer ring set of left side driving head (8) (9), with the crush-cutting direction of major axis (1) antithesis, promptly produce moving to the left, and the drive curtain draws back to the left.Make motor (7) antiport when needs are closed again, its action transmission process is opposite with opening the curtain process.

Claims

1, a kind of electronic anodontia worm drive traction curtain open/close device, it is characterized in that: a rotatable major axis (1) is by two movable pedestals (2) location, movable pedestal (2) is fixed on the sole of bottom belt length groove (16), major axis (1) goes out an end of movable axis frame (2), join by coupling band (4) and reduction box (5), and it is fixing with set screw (6), reduction box (5) other end links to each other with motor (7), be with two power transmission heads (8) on the major axis (1), three eel-like figure rollers (10) at a distance of equity are arranged in the outer ring set of driving head (8) (9), three eel-like figure rollers (10) in two driving head (8), arrange with same angle of inclination and opposite incline direction respectively, be pressed on the major axis (1), roller (10) is connected with outer ring set (9) by a sheet (11) at two ends respectively, there is a back-moving spring (15) outer ring set (9) lower end, outer ring set has a smooth block (12) bottom, Rod-shape hand apparatus for open and dose curtain (13) links to each other with smooth block (12), also has some follower rollers (16) that have curtain link (17) on the sole (3).
