Abstract
The utility model relates to a position varying and width regulating device for roller shutters, which is mainly used for solving the problem of the displacement of the roller shutters and is characterized in that the center of a reel is provided with a spindle of which both ends are provided with chain wheels and worm wheels. The worm wheel of one end forms a scarf joint with the chain wheels, and the worm wheel of other end is fixedly connected with the reel. Engaged worms are arranged under the worm wheels of both ends of the spindle. One end of the worm is provided with the chain wheels. Both ends of the reel are provided with casings for covering the chain wheels, the worm wheel and the worms. The casing chambers of the casings are provided with chain leading grooves, worm supporting seats and chain wheel grooves. One side of each casing close to the reel is provided with a reel hole. The utility model can be combined with a bead chain-shaped window cord for use of places which need shield the middle and the lower parts of windows.
Description
The utility model relates to the displacement amplitude modulation apparatus of window treatment.
The roller blind device of prior art is a spool, at the spool two ends sprocket wheel is housed, and this sprocket wheel adapted bead chain shape window rope affects, and drives the spool rolling or the curtain of releasing.Can realize that by this device of what curtain blocks the adjusting of length, be considered as usually curtain length to amplitude modulation apparatus, this device fixedly hangs on upper window edge, inconvenience arbitrarily changes its position, can not adapt to the needs in a shielding window bottom or window centre position.
The purpose of this utility model provides a kind of roller shutter displacement amplitude modulation apparatus.
The utility model comprises the sprocket wheel of spool and adapted bead chain shape window rope, a mandrel is inserted at the center that it is characterized in that spool, two external parts of mandrel are installed a sprocket wheel respectively, one side of two ends sprocket wheel puts a worm gear respectively on mandrel, the wherein worm gear of an end and sprocket wheel interlocking, the worm gear of the other end is fixedlyed connected with the end of spool, all there is an engaged worm worm gear below at mandrel two ends, the end of worm screw is equipped with sprocket wheel, the spool two ends are with a containing sprocket wheel respectively, worm gear, the housing of worm screw, the shell chamber of housing has the guide chain groove that is communicated with up and down, and the housing Lower Half is provided with supporting base and the sprocket groove of worm screw, and housing near reel one side has the spool hole.
The utility model is fixedlyed connected worm gear at an end of spool with spool, when this worm gear is promoted by worm screw, spool is rolling or drainage curtain, be provided with the mandrel that turns round respectively with spool by what the utility model, when the sprocket wheel of mandrel one end by with the worm gear drives of its interlocking the time, therefore the sprocket wheel at mandrel two ends can be creeped along the bead chain shape window rope that is fixed in the window both sides, adopts this device and bead chain shape window knot to close not only and can carry out amplitude modulation but also can regulate the position of blocking of roller shutter roller shutter.
Accompanying drawing 1 is an assembling schematic diagram of the present utility model, and accompanying drawing 2 is schematic diagrames that guide chain groove, sprocket groove, worm screw supporting base are set in the housing.
The shaft core position that is illustrated in spool 1 among Fig. 1 is inserted in a mandrel 2, sprocket wheel 5 and sprocket wheel 16 are installed respectively at the mandrel two ends, on the mandrel of sprocket wheel inboard, put worm gear 3 and worm gear 17 respectively, worm gear 3 has concavo-convex body or pin 4 interlockings with sprocket wheel 5, worm gear 17 has steady pin or screw 18 to fixedly connected with spool, the below of worm gear 3 is worm screws 6, the end of worm screw 6 has sprocket wheel 7, the below of worm gear 17 is worm screws 15, the end of worm screw 15 has sprocket wheel 14, the inboard of housing 8 and housing 11 covers on the two ends of spool respectively, the bead chain shape window rope that 9 and 12 expression window both sides set among the figure, the bead chain shape window rope of 10 and 13 expression adapteds on worm screw one end sprocket wheel among the figure.
Accompanying drawing 2 expression guide chain grooves 19 up/down perforations, the curved shape of middle part cell wall constitute a groove cave that holds mandrel end sprocket wheel 5 or 16 between two curvilinear flutes, the bead chain shape window rope 9,12 that is fixed on the window both sides can be along guide chain groove 19 and sprocket wheel 5 or 16 engagements; On the both sides of lower guide key way 19 are a pair of worm screw supporting bases 20, one side worm screw supporting base 20 be the sprocket groove 21 that holds worm screw one end sprocket wheel 7 or 14, the bead chain shape window rope 10 of traction worm screw one end sprocket wheel or 13 is in this sprocket groove 21 and sprocket wheel 7 or 14 engagements.
Best way of the present utility model is that the spool hole of housing near reel 1 one sides is made anti-limit along the direction of parallel spool 1 in housing, not only can increase the firm of housing but also can keep housing vertical with spool, helps keeping the normal use of this device.
