Description of drawings
A kind of day and night curtain controlling organization main body explosive view that can descend automatically of Fig. 1 the utility model;
A kind of day and night curtain controlling organization locator explosive view that can descend automatically of Fig. 2 the utility model;
A kind of day and night curtain controlling organization retarder explosive view that can descend automatically of Fig. 3 the utility model.
The specific embodiment
With reference to figure 1, a kind of day and night curtain controlling organization that can descend automatically that the utility model provides comprises system headstock 10, system skull 20, left clutch 30, right clutch 40, transmission mechanism 50, locator 60 and retarder 70.
Right clutch 40 comprises that rotational arm of clutch 41, clutch mandrel 42, spring 43, torsion spring 44, clutch sheave 45, clutch break away from cover 46, clutch breaks away from joint 47, and described rotational arm of clutch 41, clutch mandrel 42, spring 43, torsion spring 44, clutch sheave 45, clutch break away from cover 46, clutch breaks away from joint 47 and is connected in series and is positioned over the through hole that is arranged in system headstock 10 the right successively.
Retarder 70 comprises retarder seat 71, the retarder axle 72 of band gear, friction plate 73, planetary gear 74, pinion frame 75, retarder lid 76, described brake pad 73 places an end of the retarder axle 72 of band gear, retarder axle 72 gears, one end of band gear and 74 engagements of described planetary gear, described planetary gear 74 places on the pinion frame 75, and described planetary gear is 3, and space 120 degree are installed on described planetary wheel carrier 75 circumference, the retarder axle 72 engagement ratios of planetary gear 74 and band gear 1: 3 can make retarder axle 72 realize quickening like this; Because described brake pad 73 is made of metal crescent shape, its center of gravity is away from described band gear retarder axle 72 1 ends, brake pad 73 external peripheral surfaces are fixed with friction plate, brake pad 73 is thrown toward retarder seat 71 inwalls when retarder axle 72 rotates at a high speed, frictional force by brake pad 73 and retarder seat 71 inwalls stops retarder axle 72 rotating speeds to improve, thereby realizes that day and night the automatic slowly of curtain descends.
Has boss 71-1 on the described retarder seat 71 1 end excircles, described boss 71-1 has through hole, described retarder lid 76 have that the through hole that has with boss 71-1 interlocks and profile, described retarder lid 76 is fastened on the retarder seat 71 by profile.
When the day and night curtain that needs the left side rises, spur slide fastener 51 left and can drive sprocket wheel 52 rotations, the connection gear 53 that is connected with sprocket wheel 52 1 ends is followed sprocket wheel 52 and is rotated, the Left Drive gear 54-1 and the right travelling gear 54-2 that connect gear 53 drives and its engagement rotate, Left Drive gear 54-1 drives rotational arm of clutch 31 and rotates, rotational arm of clutch 31 is stirred torsion spring 34 and is driven clutch sheave 35 and rotates, clutch sheave 35 promotes clutch again and breaks away from cover 36 and 37 engagements of clutch disengaging joint, make clutch break away from joint 37 and rotate, thus make with clutch break away from the left side that joint 37 is connected day and night the curtain rotating shaft rotate and reach day and night curtain rising of the left side.Though at this moment right travelling gear 54-2 also rotates, right travelling gear 54-2 drives rotational arm of clutch 41 and rotates, rotational arm of clutch 41 is stirred torsion spring 44 and is driven clutch sheave 45 and rotates, because clutch sheave 45 is opposite with the groove of clutch sheave 35, clutch sheave 45 does not promote clutch and breaks away from cover 46 and 47 engagements of clutch disengaging joint, so, at this moment, it is what to separate with clutch disengaging joint 47 that clutch breaks away from cover 46, clutch breaks away from joint 47 and does not rotate, the right that is connected with clutch disengaging joint 47 day and night curtain rotating shaft can not rotated, and therefore, do not rise in the right day and night curtain.When the day and night curtain on the left side need stop in uphill process, as long as stop to spur slide fastener 51 left, at this moment locator 60 is in locking state, the day and night curtain on the left side can not descend, when the day and night curtain that needs the left side descends, as long as spurring slide fastener 51 downward 20-30mm left again can realize locator 60 releases, the realization left side day and night curtain descends automatically.
When the day and night curtain on needs the right rises, spur slide fastener 51 to the right and can drive sprocket wheel 52 rotations, the connection gear 53 that is connected with sprocket wheel 52 1 ends is followed sprocket wheel 52 and is rotated, the Left Drive gear 54-1 and the right travelling gear 54-2 that connect gear 53 drives and its engagement rotate, right travelling gear 54-1 drives rotational arm of clutch 41 and rotates, rotational arm of clutch 41 is stirred torsion spring 44 and is driven clutch sheave 45 and rotates, clutch sheave 45 promotes clutch again and breaks away from cover 46 and 47 engagements of clutch disengaging joint, make clutch break away from joint 47 and rotate, thus make with clutch break away from the right that joint 47 is connected day and night the curtain rotating shaft rotate and reach day and night curtain rising of the right.Though at this moment Left Drive gear 54-2 also rotates, Left Drive gear 54-2 drives rotational arm of clutch 31 and rotates, rotational arm of clutch 31 is stirred torsion spring 34 and is driven clutch sheave 35 and rotates, because clutch sheave 35 is opposite with the groove of clutch sheave 45, clutch sheave 35 does not promote clutch and breaks away from cover 36 and 37 engagements of clutch disengaging joint, so, at this moment, it is what to separate with clutch disengaging joint 37 that clutch breaks away from cover 36, clutch breaks away from joint 37 and does not rotate, the left side that is connected with clutch disengaging joint 37 day and night curtain rotating shaft can not rotated, and therefore, do not rise in the left side day and night curtain.When the day and night curtain on the right need stop in uphill process, as long as stop to spur slide fastener 51 to the right, at this moment locator 60 is in locking state, the day and night curtain on the right can not descend, when the day and night curtain on needs the right descends, as long as spurring slide fastener 51 downward 20-30mm to the right again can realize locator 60 releases, realization the right day and night curtain descends automatically.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
