Abstract
The utility model relates to a universal electric curtain machine, pertaining to the curtain electric drawing mechanism, in particular to the curtain drawing mechanism. The transmission mechanism of the utility model adopts gradually transmission connected a gear, a worm and a worm wheel which are; the two sides of the worm wheel are respectively connected with a range of inverted ratchet wheels whose directions are opposite; the inverted ratchet wheels are respectively provided with a winding wheel; the tips of a drawing line are respectively fixed on the winding wheels and the middle part of the drawing line covers on a reverse wheel. The curtain mechanism has the advantages of simple structure, small volume, low manufacturing cost and convenient mounting, applicable for the curtains with various widths.
Description
Technical field
The utility model belongs to the haulage gear of the electric traction mechanism, particularly curtain of the door curtain made of cloth.
Technical background
Traditional electric controller for curtain has plenty of and relies on motor to move in track to draw curtain, and what have then is to drag curtain with driven by motor loop pulling line.Above-mentioned continuous cropping mechanism is all comparatively complicated, and cost is higher, installs very inconveniently and more time-consuming, when each different time of curtain width, trouble more is installed, need blanking exactly.Preceding a kind of mechanism is easily stuck in track after use a period of time, causes burn-down of electric motor; It is suitable that back one mechanism need adjust the loop pulling line, when tension power consumption many, then easily skid when crossing pine.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of general electric window curtain driving mechanism, and simple in structure, volume is little, and low cost of manufacture is easy for installation, the curtain of suitable various width.
Solving the scheme that technical problem of the present utility model adopts is: the transmission mechanism of window curtain driving mechanism adopts gear, the worm and worm wheel that are in transmission connection step by step, the both sides of worm gear are connecting the opposite barb wheel of a cover direction respectively, have reel on the barb wheel, the termination of draught line is separately fixed on each reel, and the draught line middle part is enclosed within on the reverse wheel.
What this window curtain driving mechanism was taked is the driven by motor transmission mechanism, makes draught line move the traction curtain again, is simple, gear, worm and worm wheel mechanism reliably and transmission mechanism adopts, does not therefore need higher precision just can reach the work purpose well; Two overlap the mode that the wheel of barb is independently fixedlyed connected with reel, can collect long draught line, and when a cover barb wheel joggleword, another set of barb wheel disengages, thereby can guarantee that draught line always is in tension, no matter width that can curtain during installation how, need not to adjust and just draught line strained automatically, simplify fitting operation greatly, save time.
Description of drawings
Fig. 1 is the structural representation of facing of the present utility model;
Fig. 2 is a plan structure schematic diagram of the present utility model.
Each label is represented successively among the figure: motor 1, driving gear 2, driven gear 3, worm screw 4, worm gear 5, reel 6,7, spring leaf 8,9, draught line 10, barb wheel 11, casing 12, pin 13.
The specific embodiment
Referring to Fig. 1,2, what the transmission mechanism of this window curtain driving mechanism adopted is gear 2,3, worm screw 4 and the worm gear 5 that is in transmission connection step by step, be that driving gear 2 in the transmission mechanism is loaded on the output shaft of motor 1, and be meshing with each other with driven gear 3, and that driven gear 3 and worm screw 4 are loaded on is coaxial, worm screw 4 again with worm gear 5 engagements.Connecting the opposite barb wheel 11 of a cover direction respectively in the both sides of worm gear 5, the structure of this described a whole set of barb wheel 11 is two and has ratchet and ratchet face opposite circular, a slice is connected with worm gear 5, together rotate thereupon, another sheet then has reel 6,7, two terminations of draught line 10 just are separately fixed on the reel 6,7 of each side, and the middle part of draught line 10 is enclosed within (conventional method is drawn among the figure) on the reverse wheel of window opposite side again.The worm gear 5 of this window curtain driving mechanism with the connected mode of barb wheel 11 is, has a pair of pin-and-hole (block, draw) on the worm gear 5, and a pair of pin 13 of barb wheel 11 usefulness of both sides is fixed into one, and the pin-and-hole on pin 13 and the worm gear 5 movingly.When motor 1 is just changeing, worm gear 5 drives barb wheel 11 by pin 13, at casing 12 and 6,7 spring leafs that compressing 8,9 of reel a cover barb wheel 11 is wherein meshed, reel 7 is along with rotation, tighten up draught line 10, another set of barb wheel 11 is because of direction is opposite, and ratchet breaks away from, and reel 6 is along with other side take-up and the unwrapping wire that dallies.Otherwise, during motor 1 counter-rotating, reel 6 take-ups, reel 7 unwrapping wire.Like this, when mounted just not the width of window of tube how need not adjust the degree of tightness of draught line 10 specially, as long as this device is installed, motor just can be suitable with draught line 10 adjustment in rotation process.
