Embodiment
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
The utility model forms framework uses aluminium alloy extrusions, and four aluminium alloy type edges of forms are socketed with four corner modelings
Materials and parts, are stitched together.Forms framework medial roof end is provided with the adjusting rod 6 for regulation shutter blade inclination angle.Described
The two ends of adjusting rod 6 are separately mounted to the mounting seat in forms framework, on lifter 1, and the cross section of adjusting rod 6 is polygon, is easy to
Various rollers are installed thereon.
The middle part of adjusting rod 6 is arranged on two diverters 7.The T-shaped base of described diverter 7 is plugged on forms dividing plate
On slot, base, which is provided with, is used for the through hole through drawstring 4.The frame bottom of diverter 7 is provided with roller 8, the rope for mitigation
Friction, drawstring 4 is connected across roller 8 with window blind assembly.
The deflecting adjusting rope 10 of shutter deflecting component is wrapped in 1-3 on the deflecting wheel 9 of adjusting rod 6 or adjusting rod 6 and enclosed.
For lifting the drawstring 4 of shutter across the deflecting driving wheel 2 on adjusting rod 6, the roller inside boosted device 1 is
Reverse wheel 3 commutates, and vertical trend is changed into being horizontally orientated to, and is finally connected with window blind assembly.Deflecting driving wheel 2 is built in lifter
1, the right-hand member of adjusting rod 6 is arranged on the bearing block of lifter 1.
When the blade of shutter is transferred completely, drawstring 4 across or bypass some circle deflecting driving wheels and then drive adjusting rod
6, therefore, the movement of drawstring 4 can drive blade of louver window inclination angle to change.Drawstring 4 is pulled down, and following change occurs for blade state：
Close, open, close.After closure, drawstring 4 continues to move down, because the deflecting adjusting rope 10 of side has been tensioned completely, deflecting
Skidding occurs on deflecting wheel 9 for adjusting rope 10, and blade of louver window inclination angle will not change.Drawstring 4 can be constantly by shutter leaf
Piece is lifted, until being raised to peak.After optional position stops in the way of lifting, shutter occupies a window part.After stopping,
Drawstring 4 is moved up, and skidding will disappear, and the side deflecting adjusting rope 10 of tensioning is transferred and loosened, and opposite side will be received
Tightly, blade tilt will change.In summary, shutter moves to optional position, can control drawstring 4, and then drive
Deflecting wheel 9 rotates, and brings the change of blade pitch angle.
As shown in figure 3, cord winder includes bull wheel 1104 and gear, gear is used to provide two kinds of windings
Speed, one kind is to accelerate tooth ratio, for providing faster speed of wrap, improves the lifting speed of shutter, is particularly suitable for use in big
Size window；One kind is reducing gear ratio, the slow speed of wrap for providing, the angle for facilitating regulation shutter blade.Hundred
Leaf window adjustment of blade angle stroke very little, it is easy to miss, therefore need to adjust at a slow speed.
Gear driving shaft is connected with rocking handle 1102, and two driving gears are distributed on driving shaft, are connected with bull wheel 1104
Two driven gears are distributed with the driven shaft connect.Driving wheel one is more than 1 with the gearratio of driven pulley one, is deceleration transmission.Actively
Wheel two is less than 1 with the gearratio of driven pulley two, to drive up.When driving wheel one is engaged with driven pulley one, driving wheel two with it is driven
Wheel two is not contacted；Driving shaft is to the left after side slip, and driving wheel two is engaged with driven pulley two, and driving wheel one does not connect with driven pulley one
Touch.Driving shaft outer end is provided with rocker sleeve 1107, and rocker sleeve 1107 carries the stopper slot 1108 coordinated with limiting card 1101.
Driving shaft is arranged on the axle bed on housing, can left and right sliding.Driving wheel one and the spacing of driving wheel two are more than etc.
In the width of driven pulley two.Driven gear gap is zero.Aforementioned four gear both sides are respectively mounted spacer pin.Spacer pin is arranged on master
On the stopper slot of axle, spacer pin is as shown in figure 4, be the elastic circular ring with opening.
The inner band of stopper slot 1108 above rocker sleeve has the inclined-plane smoothly skidded off for limiting card.Limiting card 1101 is hinged
On the outside of gear, the jointed shaft of limiting card 1101 is provided with torsion spring.Limiting card 1101 is arc sheetmetal, all the time with rocker sleeve
1107 contacts.Driving shaft and four gear thickness of driven shaft are equal, when limiting card 1101 coordinates with left side stopper slot, driving wheel one
It is at a fully engaged with driven pulley one；When limiting card 1101 coordinates with right side stopper slot, driving wheel two and driven pulley two are at a fully engaged.
Crank 1103 is hinged on rocking handle 1102, without when can fold.Connecting plate is carried on gear box body
1106, connecting plate 1106 is arranged on the right side of shutter.
The box body for being provided with gear is arranged on the exposed to contact shutter framework arbitrary height of ordinary person, it is to avoid partly use
Family does not reach the drawstring or outer slide for regulation.When using, handle is pressed inward against, until limiting card 1101 is stuck in the right side
Inside side channel so that driving wheel two and driven pulley two are at a fully engaged, faster lifting speed can be obtained, for lifting blinds
Window.Highly regulation is finished, gently draw-out handle, until up to limiting card 1101 is stuck in inside left side groove, to obtain reducing gear ratio,
The slowly lifting of drawstring 4 is may be such that, for regulation shutter blade corner.Prevent too fast speed and miss angular adjustment when
Machine.
The parbuckle of the utility model one has been provided simultaneously with the function of lifting and conversion angle, simplifies structure, also simplify control
Process processed.Cord winder include bull wheel and gear, gear combined with bull wheel can realize fast lifting and
Angle modulation at a slow speed, accomplishes that speed is taken into account, using very convenient.
