Description
Technical field
The present invention relates to a kind of rolling wheel accessory of shutter, particularly relate to a kind of sequential clutch for clutch control reel system of shutter.
Background technology
Publication number is the concept that the Chinese invention patent of CN102839909A proposes variable pitch window shutter, variable pitch window shutter can provide abundanter louvre blade spacing regulative mode, obtain more various illumination, temperature Adjustment effect, meet the requirement that people improve day by day to healthy and life grade aspect better, 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 variable pitch window shutter and reel system, it is promoted by the end projection of a upper rolling wheel that the such mode of the end projection of next rolling wheel obtains that the rolling wheel of these mechanisms and internal system rotates, thus the anglec of rotation of each rolling wheel all can not more than 360 °, thus, the size of rolling wheel diameter must with the pitch size change between louvre blade width and louvre blade, louvre blade is wider, pitch between louvre blade is larger, rolling wheel diameter is also larger, otherwise limited rolling wheel rotational angle cannot obtain 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, head track apparent visual is caused not meet the esthetic requirement of people.For this reason, be necessary to be further improved the relevant wheel mechanism for rolling of this type of variable pitch window shutter and reel system.
Summary of the invention
In order to overcome existing variable pitch window shutter reel system in rolling wheel rotate can not more than 360 °, rolling wheel not easily realizes miniaturization, cause whole reel system and even the too fat to move defect of corresponding shutter head track volume, the invention provides a kind of rolling wheel can continuous rotation, thus greatly can reduce rolling wheel size and even whole reel system and corresponding shutter head track volume, and don't affect the sequential clutch for clutch control reel system of shutter of louvre blade regulation by pitch effect.
Technical scheme of the present invention is: the sequential clutch for clutch control reel system of shutter, for the variable pitch window shutter with one group of main ladder band and three groups of secondary ladder bands, comprise a time rolling wheel, secondary two rolling wheels, secondary 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 upset cylinder extremely upset cylinder top, 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 after upset cylinder barrel 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 overturning axis and radial location on cylinder with upset cylinder, torsional spring clutch is in transmission connection with upset cylinder and is also provided with inner circular tooth, 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.When opening with one group of main ladder band and three groups of secondary terraced variable pitch window shutter be with, the first tetrad of louvre blade pulls open spacing between group, often comprise a main louvre blade and three secondary louvre blades in group, as louvre blade spacing need be pulled open further, louvre blade in each group pulls open sequentially again (as be one by one separated or divide half-and-half for twice from), make each louvre blade monomer mutually keep a determining deviation, carry out the integrated regulation at louvre blade inclination angle on this basis again.Otherwise, shutter draw in time process then with said process contrary.When the sequential clutch for clutch control reel system of this shutter works, external force inputs from rotating shaft, rotating shaft can driven gear axle and rolling wheel continue to rotate, because gear shaft is threaded with torsional spring clutch, gear shaft can produce when rotating and move axially, therefore the rolling wheel with inner circular tooth is not keep engaging with the rolling wheel and torsional spring clutch of being with inner circular tooth all the time, but to engage respectively with certain sequential along with the variation of axial location or depart from engagement, when being with the rolling wheel of inner circular tooth to engage with the corresponding gear on gear shaft, rolling wheel is just along with gear shaft rotates together, reel when each rolling wheel rotates 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 and turn over drum rotation, then changes the relative position of the forward and backward rope of all ladder bands, the overall angle of inclination changing louvre blade.Therefore, by the control of the sequential clutch for clutch control reel system of this shutter, each louvre blade by according to opportunity of engaging of gear each on gear shaft and each rolling wheel and torsional spring clutch and order with pitches and Inclination maneuver in certain sequential realization group.
