Description
Technical field：
It the utility model is related to a kind of curtain technology.
Background technology：
Existing rolling screen without pull rope is generally provided with rebounding mechanism, in use, pulling curtain, curtain is released from spool
Release, to open curtain, meanwhile, rebounding mechanism savings resilience kinetic energy, when needing in curtain backrush backrush axle, touch
Rebounding mechanism, rebounding mechanism is in the case where the power of resilience accumulation of energy drives, by curtain backrush backrush axle.Such a roller shutter, no matter roller shutter
Open（Winding）To that position, it is required for touching rebounding mechanism, so that roller shutter is stopped on the position of setting, moreover, touching
During rebounding mechanism, determined by the structure of the touch device of rebounding mechanism, roller shutter be required for backrush it is certain and it is uncertain away from
From the length for causing roller shutter to discharge is not accurate enough, uses very inconvenient.
Utility model content：
Goal of the invention of the present utility model is that providing one kind can make roller shutter release, winding convenient, roller shutter release curtain
Length is controllable and accurate roller shutter.
The utility model is achieved in that the reel for having curtain including support, the volume being rotatably arranged on support, set
Resistance gauge in reel wherein one end, the backrush spring for being arranged on the reel other end, the spring free end and reel of backrush spring
Connect and rotated with spool turns, the connection end of backrush spring is connected on the support on the reel other end, and resistance gauge includes
Screw rod with connecting portion, rotate the pipe sleeve being socketed on connecting portion, be arranged on connecting portion and before pipe sleeve pressure end
Friction plate, be screwed on screw rod nut, wear the spring being connected on screw rod and between nut and friction plate, the company of resistance gauge
Socket part is connected on support of the reel wherein on one end.In use, pulling curtain, curtain is set to be discharged from reel, meanwhile,
The rotating cylinder of rotation makes the elastic force of backrush spring savings revolution, rotates along screw rod with the nut rotated and is moved to connecting portion direction
Dynamic, increased pressure is applied on friction plate by extrusion spring, the spring being extruded, and friction plate is applied to pipe sleeve pressure end
Pressure increases, and frictional force also increases, and stops that curtain discharges from reel, due to the release of curtain, the weight of curtain
The power of curtain release is also increased, so as to which a part counteracts the elastic force of backrush spring savings revolution, moreover, friction plate is applied to
The frictional force of pipe sleeve pressure end is more than the elastic force of backrush spring savings revolution plus the gravity of discharged curtain, meanwhile,
The frictional force that friction plate is applied to pipe sleeve pressure end is more than discharged curtain plus the elastic force of backrush spring savings revolution
Gravity, and the elastic force of backrush spring savings revolution is more than friction plate and is applied to the frictional force of pipe sleeve pressure end, so, is not having
During the effect of external force, reel can neither discharge casement, meanwhile, discharged curtain can not be wound back again, only in external force
Under effect, such as pulled down curtain, curtain could discharge or hold up curtain from reel, to offset the window discharged
The gravity of curtain, reel could wind the curtain of retraction release, so as to realize the purpose of utility model of present patent application.
Here, platen is provided between friction plate and spring, platen is socketed on connecting portion and moved axially along connecting portion.
Using platen, the force area that spring is applied on friction plate is added, enables friction plate uniform stressed, ensures that friction plate can have
Effect ground equably applies frictional force to pipe sleeve pressure end.
Compared with the prior art, having can make roller shutter release, winding convenient to the utility model, the length of roller shutter release curtain
Spend the advantages of controllable and accurate.
