The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please refer to Fig. 1 and Fig. 2, the operating mechanism in the utility model is applied to roller shutter window 10 (seeing Fig. 3), and this operating mechanism comprises centration axis 20, is sheathed on torsion spring 30, fixation kit 40, driving member 50, fixed block 60 and hollow door-hinge 70 on the centration axis 20.Hollow door-hinge 70 first ends and the second end are connected on fixation kit 40 and the driving member 50.Centration axis 20, torsion spring 30 and fixed block 60 all are contained in the hollow door-hinge 70.
Preferably, centration axis 20 is pvc pipe.Preferably, hollow door-hinge 70 is hollow section, and its cross section is octagon.In other embodiments, the cross section of hollow door-hinge 70 also can be other shape.
Fixation kit 40 comprises fixed head 42, two bearings 44 and the carriage cover 46 that is fixed on the wall.One side of fixed head 42 is extended with stair-stepping torsion spring carriage 422, and preferably, torsion spring carriage 422 is perpendicular to the end face setting of fixed head 42.The first end of centration axis 20 is enclosed within the end of torsion spring carriage 422 rotationally.One end of carriage cover 46 is fixed in the first end of hollow door-hinge 70, and preferably, carriage cover 46 is hollow section, and its outer peripheral edges are octagon.Torsion spring carriage 422 is enclosed within the carriage cover 46 pivotly by two bearings 44.In other embodiments, the outer peripheral edges of carriage cover 46 also can be other shape, as long as identical with the cross section of hollow door-hinge 70.
Driving member 50 comprises axle 51.Matching of the shape of axle 51 and hollow door-hinge 70 is so that the second end of fixation hollow door-hinge 70.Preferably, in the present embodiment, the cross section of axle 51 is octagon.
Concrete, driving member 50 can be passed to axle 51 with hand power by worm-and-wheel gear, and drives hollow door-hinge 70 rotations by axle 51, thereby rolls or put down roller shutter window 10.In other embodiments, also can transmit hand power to pitch wheel by many.
Fixed block 60 comprises head 62 and the tube connector 64 that is extended by the side of head 62.Tube connector 64 is provided with a fixing hole 642, is used for fixedly torsion spring 30.The second end of centration axis 20 is fixed in tube connector 64, and preferably, the cross section of head 62 is octagon.
Fig. 3 has been described in detail the overall structure of the roller shutter window operating mechanism in the utility model.As shown in Figure 3, centration axis 20 is passed torsion spring 30, and the first end of centration axis 20 and the second end are installed on respectively torsion spring carriage 422 and tube connector 64.One end of torsion spring 30 is stuck in the fixing hole 642, and the other end of torsion spring 30 is fixed in the fixing hole 421 of torsion spring carriage 422.Hollow door-hinge 70 is enclosed within the outside of centration axis 20.At this moment, fixed block 60, torsion spring 30 and carriage cover 46 all are contained in the hollow door-hinge 70.And fixed block 60 is fixed in the hollow door-hinge 70 by its octagonal head 62, therefore can rotate with hollow door-hinge 70.The first end of hollow door-hinge 70 is fixedly sleeved on carriage cover 46, and the second end of hollow door-hinge 70 is fixedly sleeved on axle 51.Torsion spring 30 just is in the torsional deformation state when installing this roller shutter window operating mechanism, have certain initial torsion.
Below in conjunction with Fig. 4 the course of work of the roller shutter window operating mechanism in the utility model is described.As shown in Figure 4, when needs were left behind and close this roller shutter window 10, the joystick 80 of roller shutter window 10 was shaken in operation, and the motion of this joystick 80 is passed to driving member 50, was then rotated by driving member 50 band moving axis 51.At this moment, axle 51 drives hollow door-hinge 70 rotations that are fixed on the axle 51.So the roller shutter window 10 that volume hangs on the hollow door-hinge 70 descends under the effect of its deadweight.In this process, fixed block 60, centration axis 20 and carriage cover 46 rotate with hollow door-hinge 70.Torsion spring 30 continuous torsional deformations are until during the gravitational equilibrium of the elastic deformation force that torsion spring 30 produces and roller shutter window 10 self, roller shutter window 10 remains a constant speed decline until close.
When needs upwards promoted to open roller shutter window 10, the elastic deformation force of torsion spring 30 had torsion upwards to roller shutter window 10, to overcome the gravity of roller shutter window 10 self.At this moment, only need less initial motive force can open roller shutter window 10.
In other embodiments, fixed block 60 also can be one-body molded with centering door-hinge 20, namely is the part of centering door-hinge 20.
In other embodiments, this roller shutter window operating mechanism need not to arrange fixed block 60.The second end of described centration axis 20 is arranged an octagonal hold-doun nut, by this hold-doun nut the second end of centration axis 20 is fixed in hollow door-hinge 70.One end of torsion spring 30 is directly fixed on hold-doun nut.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
