Description
Technical field：
The present invention relates to a kind of curtain drive mechanism.
Background technology：
As shown in Figure 3,4, existing sleeve and roll type roller shutter release after positioning technology be revolution release device 5 with
The movable part that curtain reel 2 links together is the rotating cylinder 5b, sleeve 5a that sleeve 5a, standing part are provided in sleeve 5a
Medial wall is provided with guide groove 5c, rotating cylinder 5b surface 5d is provided with logical slideway 5e from beginning to end, between guide groove 5c and slideway 5e
It is provided with ball 5f, slideway 5e is made up of a group or more of left and right linear ramp 5e1,5e2, middle V-arrangement slideway 5e3,
Left linear ramp 5e1, one of direction of middle V-arrangement slideway 5e3 are provided with and are individually directed right linear ramp 5e2, left straight line
Targeting port 5e4,5e5 of slideway 5e1, is provided with V-arrangement slideway 5e3 in the middle of guiding on the right linear ramp 5e2 in another direction
Targeting port 5e6.During work, sleeve 5a together with curtain reel 2 power drive mechanism 3 drive under rotate, ball 5f along guide groove 5c,
Slideway 5e moves, and when the rotation direction of sleeve 5a is to make ball 5f enter right linear ramp 5e2, sleeve 5a is together with curtain reel
2 successfully rotate, and curtain is opened, and when sleeve 5a stops operating, sleeve 5a is together with curtain reel 2 in elastic rotating mechanism 4
Slightly turn round in the presence of turning power, make ball 5f pass through targeting port 5e6 and enter middle V-arrangement slideway 5e3 and be stuck in middle V-arrangement slideway
In 5e3, so that sleeve 5a can not be turned round together with curtain reel 2, until making sleeve 5a together with curtain reel by power drive mechanism 3
2 rotate along curtain opening direction, make ball 5f import left linear ramp from middle V-arrangement slideway 5e3 by targeting port 5e5
5e1, be no longer stuck in middle V-arrangement slideway 5e3, so, sleeve 5a together with curtain reel 2 elastic rotating mechanism 4 turning power
Effect is lower to turn round, and curtain is wound.This kind of technology, the positioning during release curtain, is to need first to stop drag curtain, so
Afterwards, again pulling curtain, so that ball 5f is imported targeting port 5e4 and reach targeting port 5e6, then stop drag curtain, in bullet
Slightly turn round in the presence of the turning power of power slew gear 4, make ball 5f pass through targeting port 5e6 and enter middle V-arrangement slideway 5e3 and block
In middle V-arrangement slideway 5e3, because during release curtain, corresponding left and right linear ramp 5e1,5e2 do not have obstacle, because
This, release curtain during positioning when again release curtain length be easy for different in size（As the curtain phase being discharged
When enclosing above corresponding various curtain length in spool turns one）It is often more important that when curtain needs positioning, ball is in slideway
Uncertain during interior position, so, the distance that ball moves in V-arrangement slideway 5e3 is uncertain, the impact of multiple factors
Lead to location difficulty and very inaccurate.
Content of the invention：
The goal of the invention of the present invention is to provide that a kind of structure is simple, easy for operation, accurate positioning roller shutter changes
Enter structure.
The present invention be achieved in that including Curtain rod, be connected on Curtain rod with elastic rotating component
Revolution relieving mechanism, the curtain reel being arranged on revolution relieving mechanism and elastic rotating component, it is particular in that revolution
Fixing axle that relieving mechanism includes being connected on Curtain rod, rotate the rotating cylinder being socketed in fixing axle, rotate and be socketed in rotating cylinder
On sleeve, turn, ball, curtain reel is socketed on sleeve, and set medial wall of the tube is provided with guide groove, along drum surface setting
There is logical slideway from beginning to end, slideway includes more than one functional areas, it is same that functional areas include ball importing road, wherein one road junction
When with ball import the ball that is connected of road return turnout and ball stop turnout, simultaneously with another road junction on ball return turnout and
Road derived by the ball that another road junction in ball stop turnout connects, and the medial wall at wherein one road junction on ball stop turnout is against rolling
Pearl imports the ball importing direction in road, and the ball Return-ing direction at wherein one road junction on ball return turnout imports the road in road to ball
Mouthful, be provided with ball stop notch and ball in ball stop turnout and drive recess, ball drive the opening direction of recess towards
The direction that in ball stop turnout, ball comes, ball drives the ball off-direction of recess towards ball stop notch, and ball stops
The ball off-direction of dynamic recess towards ball derive ball derive road direction, ball derive road ball Return-ing direction against
Ball returns to another road junction on turnout, and ball is arranged between guide groove and the slideway of set medial wall of the tube, and turn is socketed in fixing axle
On, wherein one end of turn is connected on rotating cylinder.
During use, the roller shutter that curtain reel is wound is pulled out, curtain spool turns, band moving sleeve rotates, sleeve edge
Drum rotation, because the medial wall at wherein one road junction on ball stop turnout imports the ball importing direction in road against ball,
Therefore, ball enters ball stop turnout and falls on ball driving recess, and can not continue to roll along slideway, drives rotating cylinder one
Play rotation, now, rotating driven turn is to rotate toward the direction opened, and the internal diameter of the turn after opening is more than admittedly
The external diameter of dead axle, therefore, turn also rotates together, when needing the roller shutter positioning by release, unclamps roller shutter, in elastic rotating
Under the drive of component, roller shutter turns round back on curtain reel, and now, sleeve, also with revolution, drives ball to fall into the rolling on rotating cylinder
In pearl stop notch, rotating cylinder is driven to have counter-rotational trend, now, because the turn that rotating cylinder is driven is toward the side tightened up
To rotate, so that the diameter of turn is diminished, turn lock ring can not rotate in fixing axle, so, rotating cylinder, sleeve nor
Rotating, thus reaching the effect of positioning, when needing to wind roller shutter, drawing roller shutter, so that sleeve is rotated, drive ball to depart from ball
Stop notch enters ball and derives road, then unclamps roller shutter, and under elastic rotating component drives, sleeve turns round, because ball is led
The ball Return-ing direction engaged in this profession returns to another road junction on turnout and the ball at wherein one road junction on ball return turnout against ball
Return-ing direction imports the road junction in road to ball, and therefore, ball enters ball and returns turnout opposite direction 5 circulating rolling without barrier,
Till roller shutter winds completely or thinks that pulling roller shutter launches toward roller shutter release direction, because ball drives recess from ball
Very short to the distance of ball stop notch, therefore, the distance of curtain backrush is also very short and is constant, so, uses
Person is just easy to carry out roller shutter release positioning.Due to only increase turn and to slideway redesign, therefore, structure letter
Single.
Compared with the prior art the present invention, has the advantages that structure is simple, easy for operation, accurate positioning.
