1, it is provided with the set-up function module for setting bottom rail arrival desired location due to motor, so can set volume
The position that cord is to be arrived, after in-position, motor automatic stop;
2, be all arranged with bottom rail tension base due to each limit rail inside lower end, outside guiding trestle on be rotationally connected convex
Wheel, cam is provided with torsion spring, and one end is connected with guiding trestle, such roller shutter cloth after a stop by bottom rail outer end assembly and
The stop of bottom rail tension base, forces motor to be made motor stalling, motor be achieved that the voltage overload self-protection that is hampered by resistance
Power down function, and solve roller shutter chance wind and easily rock the problem waved and make a noise.

Single cover plate 1, is provided with mounting bracket 13 outside Phaleria macrocarpa 12, connect single cover plate 2 14, described single cover plate one outside mounting bracket 13
11, single cover plate 2 14 lower end is arranged with inner side and opens slotted limit rail 15, and described each limit rail 15 inside lower end is all arranged with
Bottom rail tension base 21, described bottom rail tension base 21 includes inclined-plane 21.1, tensioner groove 21.2 the most successively, turns to dead slot
21.3, described bottom rail 4 two ends are equipped with bottom rail capping 16, connect guiding trestle 17, outside guiding trestle 17 outside bottom rail capping 16
Side is arranged in the groove of limit rail 15, outside guiding trestle 17 on be rotationally connected cam 18, cam 18 is provided with torsion spring 20, torsion spring 20
One end is connected with guiding trestle 17.
Described roller shutter cloth 3 is connected with bottom rail 4 by sticking plaster.
Described bottom rail capping 16 is connected by ST self threading pin and bottom rail 4 two ends are fixing.
Described cam 18 is fixed on guiding trestle 17 by bearing pin 19, and torsion spring 20 is socketed on bearing pin 19.
Described bottom rail tension base 21 is connected by ST self threading pin is fixing with limit rail 15.
Pressing switch 7 down button, motor 6 rotates and drives pipe crimping 2 to rotate, and makes the roller shutter cloth 3 being wound on pipe crimping 2 end of along with
The mass 5 of rail 4 and launch mobile, when bottom rail 4 is run to rail 15 bottom, limit, the cam 18 inclined-plane on bottom rail tension base 21
21.1 enter in tensioner groove 21.2, and now motor 6 is automatically stopped, about about three seconds, and motor 6 reversely rotates about 1/10 turn,
Making roller shutter cloth 3 be in retracted state, now cam 18 end is upward, due to by cam 18 and rising on bottom rail tension base 21
The stop of tight groove 21.2, forces motor 6 to be made motor 6 stall by resistance increase, and general resistance is located at about 20KG, when resistance reaches
During to 20KG, motor 6 quits work, and this device may insure that roller shutter cloth 3 is used below at strong breeze.
Pressing switch 7 upwards button, motor 6 rotates and drives pipe crimping 2 to rotate, make the roller shutter cloth 3 being wound on pipe crimping 2 continue to
Lower expansion is moved, about 1/9 turn, and in now cam 18 enters into and turns to dead slot 21.3, after spending three seconds, motor 6 automatic reverse revolves
Turning, make roller shutter cloth 3 be in retracted state, now cam 18 end is down, when bottom rail 4 leaves bottom rail tension base 21, and cam 18
Recovery level, then bottom rail 4 continues to rise until all regaining, and owing to being stopped with case 1 bottom end by bottom rail 4, forces
Motor 6 is made motor 6 stall by resistance increase, and general resistance is located at about 20KG, it is ensured that roller shutter cloth 3 tightens up, and prevents bottom rail 4 from existing
Wind rocks, it is to avoid produce percussion and cause noise.
