Description
Technical field
The present invention relates to the rolling wheel accessory of a kind of shutter, particularly relate to single two points and synchronize the lifting turner of variable pitch window shutter.
Background technology
Publication number a kind of variable pitch window shutter technical scheme that has been the disclosure of the invention of CN101818616B, the technical scheme of CN101818616B has been made again further perfect by the invention that publication number is CN102839909B, propose single two points, the concept of three four points and dual two points of variable pitch window shutter, in addition, having again publication number is CN102808577B, CN102839906B, CN102900347B, CN103266847B, a series of disclosure of the invention of the CN105041173A wheel mechanism for rolling relevant to this variable pitch window shutter and reel system, the variable pitch window shutter reel system of above-mentioned announcement has a common feature, it is exactly that the blade pitgh of variable pitch window shutter is changing to can only can not toward indoor rotary closing toward outside rotary closing after minimum spacing, this causes that the blade that variable pitch window shutter loses tradition constant pitch shutter not only can overturn toward indoor but also can toward the function of outside upset.
Summary of the invention
The blade of louver window of existing employing variable pitch window shutter reel system is changing to can only can not toward indoor rotary closing toward outside rotary closing after minimum spacing, cause shutter miopragia, for overcoming this defect, the invention provides a kind of single two points and synchronize the lifting turner of variable pitch window shutter, both the blade pitgh change of shutter can have been controlled, the blade that can also control shutter rotates toward outside or indoor until closing, variable pitch window shutter light conducting direction can be adjusted better closing on scope between window and room vertical-depth.
The technical scheme is that a kind of single two points synchronizes the lifting turner of variable pitch window shutter, including torsion spring sleeve, upset cylinder mechanism, wheel mechanism for rolling, incomplete gear mechanism and base, torsion spring sleeve, upset cylinder mechanism is rotatably connected on base and both are in transmission connection by wheel mechanism for rolling, wheel mechanism for rolling and incomplete gear mechanism are in transmission connection, cylinder is inter-agency is connected by intermittent drive mechanism with upset for incomplete gear mechanism, upset cylinder mechanism is wound with the main ladder band and time ladder band that control relative deciliter of shutter adjacent blades, main ladder band top is fixed in upset cylinder mechanism, the top of secondary ladder band is connected on wheel mechanism for rolling, torsion spring sleeve is provided with power intake.The blade that this turner synchronizes variable pitch window shutter for single two points controls, in this shutter, blade can one group of change group spacing of two panels, then group in change two panels blade pitgh, blade pitgh spacing adjustment can carry out after completing all blade overall inclination angle adjustment. Torsion spring sleeve introduces external impetus, incomplete gear mechanism is driven by wheel mechanism for rolling, incomplete gear mechanism drives again upset cylinder mechanism interval to rotate discontinuously, make upset cylinder mechanism, wheel mechanism for rolling synchronous axial system sometimes, sometimes wheel mechanism for rolling rotates and overturns a mechanism and pause, owing to the top of main ladder band and time ladder band is connected on upset cylinder mechanism, wheel mechanism for rolling respectively, therefore during upset cylinder mechanism, wheel mechanism for rolling synchronous axial system, main ladder band and time ladder band also drive the blade of louver window of correspondence to synchronize upset respectively, it is achieved the rotary opening closing of blade of louver window; When upset cylinder mechanism pauses, the main ladder primary blades with driving is motionless, and the secondary ladder secondary blade with driving individually lifts, thus completing the adjustment of group intra vane spacing. When in this turner, upset cylinder mechanism and wheel mechanism for rolling operating are asynchronous, phase contrast can be produced between the two, and phase contrast also has positive and negative two kinds, when there is wheel mechanism for rolling and the resynchronisation operating of upset cylinder mechanism when positive and negative phase contrast, the different-effect that blade of louver window overturns will be produced towards outside and indoor.
As preferably, incomplete gear mechanism includes interior bearing, outer support, gear, drivewheel and driven pulley, interior bearing, outer support is fixed on base, gear, drivewheel is connected with upset cylinder mechanism driving, driven pulley is rotatably connected on interior bearing, between outer support, drivewheel includes the partial gear and the drivewheel cam that are fixed with one, drivewheel cam is provided with breach and drivewheel Locking arc, driven pulley includes the driven gear and the driven pulley cam that are fixed with one, driven pulley cam be provided with a pair relative, driven pulley Locking arc that can be chimeric with drivewheel Locking arc adaptation, partial gear, gear all engages with driven gear. when tooth on partial gear engages with driven gear, driven gear can with partial gear synchronous axial system, and then driven gear, when tooth on partial gear is disengaged from driven gear and drivewheel Locking arc is formed chimeric with driven pulley Locking arc, driven pulley is locked out and cannot follow drivewheel and rotate, and gear is also locked out. drivewheel can be produced by this kind of structure configuration to continue to rotate, and the effect that driven pulley and gear intermittence are driven, just can make between corresponding mechanism when such drivewheel, gear connect different institutions respectively or synchronize or coordinate operation with staggering the time.
As preferably, upset cylinder mechanism includes solving lock cylinder and upset cylinder, solves lock cylinder and is in transmission connection with upset cylinder, solves lock cylinder and be in transmission connection with wheel mechanism for rolling, and upset cylinder one end is closed, and wheel mechanism for rolling is nested in inside upset cylinder.
