Description
Technical field
The present invention relates to a kind of rolling wheel accessory of shutter, relate in particular to a kind of sequential clutch for clutch control rolling wheel system of shutter.
Background technology
Publication number is the concept that the Chinese invention patent of CN102839909A has proposed pitches shutter, pitches shutter can provide abundanter louvre blade spacing regulative mode, obtain more various illumination, temperature is adjusted effect, meet better people to requirement healthy and that life grade aspect improves day by day, simultaneously, publication number is CN102808577A, CN102839906A, CN 102900347A, every Chinese invention patent application of CN102808572A discloses the wheel mechanism for rolling relevant to this type of pitches shutter and rolling wheel system, the rolling wheel rotation of these mechanisms and internal system is that the such mode of end projection that promotes next rolling wheel by the end projection of a upper rolling wheel obtains, thereby the anglec of rotation of each rolling wheel all can not exceed 360 °, thus, the size of rolling wheel diameter must change with the pitch size between louvre blade width and louvre blade, louvre blade is wider, pitch between louvre blade is just larger, rolling wheel diameter is also just larger, otherwise limited rolling wheel rotational angle cannot be obtained enough ladder band rolling distances, this limitation of rolling wheel size can cause whole wheel mechanism for rolling and system and corresponding shutter head track volume too fat to move, cause head track outward appearance vision not meet people's esthetic requirement.For this reason, be necessary that the wheel mechanism for rolling relevant to this type of pitches shutter and rolling wheel system are further improved.
Summary of the invention
In order to overcome rolling wheel rotation in the rolling wheel system of existing pitches shutter, can not exceed 360 °, rolling wheel is difficult for realizing miniaturization, cause whole rolling wheel system and even the corresponding too fat to move defect of shutter head track volume, the invention provides a kind of rolling wheel can continuous rotation, thereby can greatly dwindle rolling wheel size and even whole rolling wheel system and corresponding shutter head track volume, and don't affect the sequential clutch for clutch control rolling wheel system of the shutter of louvre blade regulation by pitch effect.
Technical scheme of the present invention is: the sequential clutch for clutch control rolling wheel system of shutter, for the pitches shutter with one group of main ladder band and three groups of secondary ladder bands, comprise a time rolling wheel, inferior two rolling wheels, inferior three rolling wheels, upset cylinder, the capping of upset cylinder, gear shaft, torsional spring clutch and rotating shaft, before all four groups of ladder bands, rear grommet is around an extremely upset cylinder top of upset cylinder, before main ladder band, rear bitter end head is connected on upset cylinder, before three groups of secondary ladder bands, rear bitter end head through upset cylinder barrel after respectively correspondence be fixed on described three rolling wheels, upset cylinder capping and torsional spring clutch are positioned at upset cylinder two ends, rotating shaft runs through all rolling wheels and torsional spring clutch, three rolling wheels are rotationally connected with on upset cylinder, gear shaft and a rolling wheel are connected with rotating shaft transmission, another two rolling wheels are provided with inner circular tooth, each rolling wheel is coaxial and axial and radial location on upset cylinder with upset cylinder, torsional spring clutch is in transmission connection and is also provided with inner circular tooth with upset cylinder, gear shaft is threaded with torsional spring clutch, gear shaft be provided with respectively can with the gear of rolling wheel inner circular tooth and the corresponding clutch of torsional spring clutch inner circular tooth.While opening with the pitches shutter of one group of main ladder band and three groups of secondary ladder bands, the first tetrad of louvre blade pulls open spacing between group, in every group, comprise a main louvre blade and three secondary louvre blades, as need be further pulled open louvre blade spacing, louvre blade in each group pull open sequentially again (as one by one separate or divide half-and-half for twice from), make each louvre blade monomer mutually keep a determining deviation, carry out again on this basis the entirety adjustment at louvre blade inclination angle.Otherwise, shutter draw in time process with said process contrary.During the sequential clutch for clutch control rolling wheel system works of this shutter, external force is inputted from rotating shaft, rotating shaft can driven gear axle and a rolling wheel continue to rotate, because gear shaft is threaded with torsional spring clutch, gear shaft can produce and move axially while rotating, therefore with the rolling wheel of inner circular tooth, be not to keep engaging with rolling wheel and torsional spring clutch with inner circular tooth all the time, but along with the variation of axial location is engaged respectively with certain sequential or departs from engagement, when the rolling wheel with inner circular tooth engages with the corresponding gear on gear shaft, rolling wheel is just along with gear shaft rotates together, when each rolling wheel rotates, reel or launch corresponding secondary ladder band, the spacing of other louvre blade in changing corresponding louvre blade and organizing.When torsional spring clutch engages with the corresponding gear on gear shaft, torsional spring clutch can drive upset cylinder to rotate, and then changes the relative position of all ladders with forward and backward rope, and entirety changes the angle of inclination of louvre blade.Therefore, the control of the sequential clutch for clutch control rolling wheel system by this shutter, each louvre blade by according to the opportunity of engaging of each gear on gear shaft and each rolling wheel and torsional spring clutch and order with pitches and Inclination maneuver in certain sequential realization group.
