Operation principle:
Under powering-off state, by hand rotation manual worm screw 21, manual worm 21 is meshed with the worm gear 22a of worm-wheel shaft 22 thus drives worm-wheel shaft 22 to rotate, then is driven planetary gear 23 synchronous axial system by the planet tooth 22b on worm-wheel shaft 22 other end；And planetary gear 23 matches with the inner gear housing 24 of periphery, owing to inner gear housing 24 is stationary state, planetary gear 23 constitutes a reducing gear in inner gear housing 24 in autorotation；The rotation of worm-wheel shaft 22 also can drive driving head 25 to rotate, and driving head 25 is connected with the outer tube of motor, thus realizes the rolling screen door emergent rising under powering-off state or decline.
The head number of manual worm 21 is 1, and the number of teeth of the worm gear 22a of worm-wheel shaft 22 is 19 teeth, then the effect of the reducing gear formed by planetary gear 23, and its total gear ratio can reach 1:81, so that whole operation is the most laborsaving.
When rolling screen door energising operating, fixing the internal tooth casing 26 that pipe matches with rolling screen door drives the intermediate drive gear 31 being meshed to rotate, then the transmission of 33, III grade of position limited gear of 32, II grade of position limited gear of I grade of position limited gear through engaging successively, IV grade of position limited gear 35 of final drive rotates；When rolling screen door run to upper limit or lower limit time, the salient point 35c of IV grade of position limited gear 35 will touch the contact 61 in microswitch 6 so that motor power-off and stop operating, and then ensure rolling screen door rise or decline time safety.
Spacing setting operation:
Upper limit sets: first stirred to the center position of device by upper limit shifting block 51, start motor to operate to rolling screen door ascent direction, the rotation of motor drives rolling screen door to fix pipe and rotates, and then drive internal tooth casing 26 to rotate, drive 32, II grade of position limited gear of 31, I grade of position limited gear of intermediate drive gear, 34, IV grade of position limited gear 35 of 33, III grade of position limited gear the most successively, rotation along with IV grade of position limited gear 35, reaching upper limit when the upper limit collision block 41 on the first runner 35a is collided with upper limit shifting block 51, now cutting off the electricity supply leaves the motor off operating；Then upper limit shifting block 51 is stirred to direction of both ends, i.e. complete the setting of upper limit.
Lower limit sets: same, first lower limit shifting block 52 is stirred to the center position of device, start motor to operate to rolling screen door descent direction, the rotation of motor drives each pinion rotation, rotation along with IV grade of position limited gear 35, reaching lower limit when the lower limit collision block 42 on the second runner 35b is collided with lower limit shifting block 52, now cutting off the electricity supply leaves the motor off operating；Then lower limit shifting block 52 is stirred to direction of both ends, i.e. complete the setting of lower limit.
Highly preferred embodiment of the present invention illustrates, those of ordinary skill in the art the various changes made or remodeling are all without departing from the scope of the present invention.
