6 function as " plane scroll spring " introduced in background technology）Tightening, elastic force increase, and the two is in equilibrium state,
The gravitional force of door curtain 5 is converted into the elastic potential energy of helical spring 6.Similarly, when electric opening rolling screen door, controller 12 connects electricity
24 circuit of coil of magnet clutch 8, makes sprocket wheel 18 and reel 4 link into an integrated entity, and controller 12 controls 7 releasing of brake of door roller again
And rotated with movable reel 4, so that door curtain 5 is increased, door curtain 5 rises its dead weight and reduces, and reel 4 drives helical spring 6 and then to relax at this time
, elastic force reduces, and for the two still in equilibrium state, the elastic potential energy of helical spring 6 is converted into the gravitional force of door curtain 5.
Under the power-assisted of helical spring 6, either close rolling screen door still open rolling screen door, as long as door roller 7 overcome chain-drive mechanism 9 and
Frictional force between door curtain 5 and guide rail 2, power can substantially reduce, energy saving, and its be supported on it is entire worked
It is balanced in journey, the working environment of door roller 7 can be improved, prolonged the service life.
When power failure manual switch rolling screen door, the coil 24 of electromagnetic clutch 8 powers off, and sprocket wheel 18 is pushed away compressed spring 31
It is moved to the left under dynamic, brake block 20 and brake ring 17 is made to detach, to which sprocket wheel 18 and reel 4 detach, reel 4 can be around spool 3 certainly
By rotating, equally under the power-assisted of helical spring 6, with hand, sliding door curtain 5 can easily be turned on and off rolling screen door upward or downward,
Manual switch rolling screen door can outer operation indoors.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.
