Axially position keeps clutch mandril 760 that pin 2 is ejected to the state of keyway, that is, keep the separation shape of output shaft 100 and worm gear
State；On the other hand, under the state, axial compression and circumferential torsion occur for torsional spring 1, therefore driving wheel 750 is losing
After external force, ratchet 710 can be driven to rotate backward, make one 780 reverse reset of torsional spring；Driving wheel 750 is rotated again, makes gib block one
751 depart from locating slot, and after gib block 1 departs from locating slot, driving wheel 750 is under the axial elastic force effect of torsional spring 1, meeting
It is moved towards ratchet 710, guide surface one is made to be bonded again with guide surface two, and clutch mandril 760 is pulled back so that pin 2 returns
Into keyway, the combination of output shaft 100 and worm gear is realized, realize that output shaft 100 and the clutch of worm gear cycle with this.The clutch
The clutch for clutch control of one 700 pairs of output shafts 100 of structure and worm gear effectively prevents the situation that driving door curtain opens and closes by mistake of motor 410, carries
The high security of the invention used.
Further, position-limit mechanism 600 includes linkage gear, train of reduction gears 610, upper limit ring to the door curtain up and down
630th, lower limit ring 620, upper limit position switch 640 and lower position switch 650；Train of reduction gears is made of multiple reduction gearing；Institute
The end that linkage gear is stated with output shaft 100 is fixedly connected；The train of reduction gears is connected with linkage gear；The lower limit ring
It is connected with upper limit ring coaxial cooperation, i.e., upper limit ring is bolted with lower limit ring, is realized and is rotated synchronously, lower limit ring
It is upper that there is engaging tooth and lower limit driving lever, there is upper limit driving lever on upper limit ring, lower limit ring passes through engaging tooth and reducing gear
Wheel group connects, and is rotated with train of reduction gears, and upper limit ring can be driven to rotate, upper limit ring and lower limit ring after rotation,
The contact of upper limit position switch can be stirred and trigger upper limit position switch by upper limit driving lever, and lower limit driving lever can be by lower position switch
Contact is stirred and triggers lower position switch.When door curtain drops to minimum point, lower limit driving lever touches the contact of lower position switch
Dynamic, circuit disconnects, and motor 410 is stopped；With should door curtain rise to lofty perch when, upper limit driving lever is by upper limit position switch
Contact touches, and circuit disconnects, and motor 410 is stopped, therefore position-limit mechanism 600 is effectively guaranteed the present invention to the door curtain up and down
Security.
Further, the elastic torsion mechanism includes connector sleeve 1, connector sleeve 2 230 and torsional spring 2 210, described

One end be connected to movable pulley 920, the other end is connected to frame 1 or ground.When door curtain fully opens, torsional spring 2 210 and bullet
In the raw, after spool 3 rotates, door curtain is begun to decline spring 2 930, and torsional spring 2 210 is twisted, and spring 2 930 is stretched,
So that the gravity of the pulling force of spring 2 930 and the sum of the twisting resistance of torsional spring 2 210 and door curtain forms substantial equilibrium, therefore driving machine
Structure reduces the power output of driving mechanism without the gravity for being subjected to rolling screen door；It can also enable door curtain in each position simultaneously
Upper remains stationary state facilitates the use of the present invention.
Further, the output shaft 100 is connected with spool 3 by belt, i.e., is equipped in output shaft 100 and connecting shaft
Belt pulley, belt are arranged between two belt pulleys, realize transmission.
In conclusion in the case of having electricity, electromagnet 840 must be electric, and lower clutch-plate is adsorbed so that upper clutch-plate and lower clutch
Piece separates, and Manual drive mechanism 500 and electric driving mechanism 400 separate, and motor 410 drives output shaft by worm and worm wheel
100 rotate, and output shaft 100 drives spool 3 to rotate, and realization puts curtain or receives curtain function；Under powering-off state, spring 1 will under from
It closes piece and pushes upper clutch-plate to, be bonded clutch-plate and lower clutch-plate, realize the worm screw of Manual drive mechanism 500 and motor 410
With reference to, pull hand-held drawing article 580, by runner 530, transmission shaft 540 worm screw driven to rotate, so as to drive output shaft 100 with
And the rotation of spool 3, it realizes roller shutter or puts the function of curtain, therefore manual drive is effectively realized by clutch 2 800
The switching of motivation structure 500 and electric driving mechanism 400；It, will using clutch 1 when roller shutter need not be driven to lift
Pin 2 ejects the keyway of worm gear, realizes the separation of output shaft 100 and worm gear, which can not drive 3 turns of spool
It is dynamic, the situation that driving mechanism drives 3 Wu of spool is effectively avoided, ensure that the security that the present invention uses.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
