Plate 1, supporting plate connect with external connecting component and device are integrally attached to external wall for installing other components
On, big sprocket wheel 2 is equipped on the left of the front surface of the supporting plate, big sprocket wheel can rotate on supporting plate, the lateral wall of big sprocket wheel
Equipped with latch for being driven, the front end of big sprocket wheel and external rolling screen door center axis connection, roller shutter door board are wrapped in rolling screen door
On central axis, big sprocket wheel rotates counterclockwise rolling screen door decline and is released, and big sprocket wheel rotates clockwise rolling screen door rising and is retracted, institute
It states and is equipped with minor sprocket 3 on the right side of the front surface of supporting plate, the lateral wall of minor sprocket is equipped with latch for being driven, and minor sprocket can prop up
Rotated on frame plate, minor sprocket is driven by a motor rotation, be driven between the big sprocket wheel and minor sprocket by chain 4, minor sprocket by
Motor drives rotation, drives big sprocket wheel rotation, the front surface of the supporting plate and equal in the outside of minor sprocket by chain drive
Even to be equipped with motor installation foot 5, motor installation foot can be extend on the through-hole on corresponding on motor, and can pass through external spiral shell
Bolt fixes motor, and the front side of the supporting plate is connected with motor 6 by motor installation foot, the output end of the motor with it is small
Sprocket wheel axis connection, motor are mounted on supporting plate by motor installation foot, and the output end of motor can be clockwise or inverse
Hour hands rotation, motor drive minor sprocket rotation, and minor sprocket drives big sprocket wheel to rotate by chain drive, and the rotation of big sprocket wheel is realized
Folding and unfolding to rolling screen door rises rolling screen door or decline, drives to rolling screen door, the middle part of the supporting plate and in big chain
The right side of wheel is equipped with bearing 7, and the inside of the bearing is equipped with shaft 8, and bearing is fixed on supporting plate, and shaft passes through bearing, and
It is fixed in the inner ring of bearing, rotates shaft on supporting plate, the lateral wall front end of the shaft is equipped with driven gear
9, the front end that driven gear is fixed on shaft rotates together with shaft, the driven gear and big sprocket wheel engaged transmission, driven tooth
The lateral wall of wheel is equipped with the latch in latch and big sprocket wheel and cooperates, and the rotation of big sprocket wheel will drive driven gear rotation, from
Moving gear is fixed to each other with shaft, and shaft is equipped with stop disc 10 also with rotation, the lateral wall rear end of the shaft, and stop disc is solid
The rear end for being scheduled on shaft rotates together with shaft, and shaft rotation rotates stop disc together, and the inside of the stop disc is uniformly set
Have and stop channel 11, stops channel and stretch wherein for spring, and is movable within for stopping latch, the stopping channel is close
The side of shaft is connected with one end of spring 12, and the other end of the spring, which is connected with, stops latch 13, and spring is in nature
It is lower that stopping latch being pulled in the inside for stopping channel, make to stop the outside that latch is not exposed at stop disc, normally receiving in rolling screen door
When putting, motor drives minor sprocket and big sprocket wheel rotation, and the velocity of rotation of big sprocket wheel is relatively slow, and driven gear also rotates relatively slowly,
Shaft and stop disc rotation are also relatively slow, and stopping latch not will receive biggish centrifugal forces affect, and after chain breakage, big sprocket wheel is lost
It goes to control, if rolling screen door is in the state opened at this time, rolling screen door, which can decline, drives big sprocket wheel quickly to rotate counterclockwise, driven
Wheel, shaft and stop disc quickly rotate clockwise, and stop latch and are acted on by biggish centrifugal force, stop latch and overcome spring
Elastic force is thrown out of stop disc, from stop channel in expose, the rear surface of the supporting plate and the outside of stop disc be equipped with stop
Ring 14, the inner sidewall for stopping ring, which is uniformly provided with, stops card slot 15, is always thrown out of if stopping latch from channel is stopped, and stops
Latch, which can snap onto, to be stopped rotating clockwise stop disc and shaft can not, so that big sprocket wheel be made not turn counterclockwise in card slot
It is dynamic, and then rolling screen door is prevented to decline, the chain then more renewed rotates clockwise big sprocket wheel by motor, keeps stop disc inverse
Hour hands rotation makes to stop latch from stopping deviating from card slot, and spring is retracted latch is stopped, and restores device.
Specifically, the upper and lower ends of the supporting plate are respectively uniformly through mounting hole 16 is equipped with, mounting hole is convenient for prop up
Frame plate is installed on external wall.
Specifically, the front surface upper and lower ends of the supporting plate are equipped with projecting plate 17, the projecting plate of downside
Upper surface is equipped with prominent latch 18, and the front position of projecting plate protrudes from the position of chain, plays certain protection to chain and makees
With, if sprocket wheel produces fracture, chain may fall downwards, fall on projecting plate, it is snapped onto chain by prominent latch,
It avoids chain from continuing to fall downwards from supporting plate, avoids chain and pound people and things to downside.
Specifically, the motor is connect with external power controling box, mentioned by external power controling box for motor
Motor is controlled for electric power, and by power controling box, motor is made to work.
Working principle: it drives minor sprocket to rotate clockwise or counterclockwise by motor, big sprocket wheel is made by chain drive
With rotating clockwise or counterclockwise, big sprocket wheel and the rolling screen door center axis connection for being externally wrapped with roller shutter door board are realized pair
The folding and unfolding of rolling screen door rises rolling screen door or decline, the rotation of big sprocket wheel will drive driven gear and rotate, turn of driven gear
Dynamic to rotate shaft and stop disc, during normal folding and unfolding rolling screen door, the velocity of rotation of big sprocket wheel is relatively slow, driven tooth
Wheel also rotates relatively slow, and shaft and stop disc rotation are also relatively slow, and stopping latch not will receive biggish centrifugal forces affect, and spring can will
Stop latch and be pulled in the inside for stopping channel, makes to stop the outside that latch is not exposed at stop disc, after chain breakage, big sprocket wheel is lost
It goes to control, if rolling screen door is in the state opened at this time, rolling screen door, which can decline, drives big sprocket wheel quickly to rotate counterclockwise, driven
Wheel, shaft and stop disc quickly rotate clockwise, and stop latch and are acted on by biggish centrifugal force, stop latch and overcome spring
Elastic force is thrown out of stop disc, and from stopping exposing in channel, stopping latch being snapped onto stopping card slot, makes stop disc and shaft
It can not rotate clockwise, to make big sprocket wheel that can not rotate counterclockwise, and then rolling screen door be prevented to decline, avoid leading because of chain breakage
It causes rolling screen door decline out of control and hurts the people on the downside of rolling screen door and things.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
