More than be the structure of the shutter elevating mechanism 20 that the utility model one preferred embodiment provides.Please cooperate again and consult Fig. 5, elevating mechanism 20 of the present utility model is to be applied to a shutter 10, and this shutter 10 includes: rail 12 on one, are fixed in the window upper limb; Once rail 14, parallel rail 12 belows that are positioned at; Some blades 16, parallel between last rail 12 and down between the rail 14; Two cotton ropes 18, two sides about vertical respectively these blades 16 of perforation.(annotate: the blade tilt control of shutter partly because of irrelevant with target of the present utility model, and should be partly adopted existing mechanism to produce with the utility model and interfere, so do not carry in this omission)
Make in the use-case at this, elevating mechanism 20 of the present utility model is last rail 12 central authorities that are installed in shutter 10, also be about to the central interior that this pedestal 30 is fixedly arranged on rail 12, and two sides about this two double-screw bolt 33 is pointed to respectively, in addition, two cotton ropes 18 of shutter 10 are fixed in the bottom side end the following rail 14 of shutter respectively, and the top side end is penetrated rail 12 inside transfer central authorities again to, that is towards elevating mechanism 20 directions extension of the present utility model, then paste along side face around to pulley 36 inboards by pulley 36 bottom sides of respective side, take advantage of a situation again spool 60 side faces of climbing up respective side and be fixed in the stack shell high order end (that is left side cotton rope 18 is fixed in the outer end of left side spool 60, right side cotton rope 18 is fixed in the inner of right side spool 60), but and rope body spiral be set around on the side face of spool 60.
Shown in Figure 3 is this shutter 10 when stretching (that is rail 14 hang down fall when near bottom side) down, the corresponding states of elevating mechanism 20 of the present utility model, at this moment, this two spool 60 is the take over end of position in movable scope all, and the only few part of the cotton rope 18 of shutter 10 is set around on the spool 60.If spool 60 is toward left dislocation (that is under the visual angle of Fig. 1 inverse clock rotation), then cotton rope 18 is understood and be furled to its side face by spool 60 spirals gradually, as being changed to by Fig. 3 as Fig. 4.Otherwise, the displacement (that is under the visual angle of Fig. 1 clockwise rotation) if spool 60 is turned right, then the rope body that originally is set around on the spool 60 of cotton rope 18 can be disengaged gradually.
Equally according to the visual angle of Fig. 1, precedingly mention that this elastic force returns and releases part 50 is the torsion of bestowing this swing arm 40 inverse clocks rotation, as bestowing the turn left torsion of screw displacement (that is spiral) of this two spool 60; On the other hand, these two cotton ropes, 18 tops are set around on the spool 60, and the bottom is subjected to down pulling under the gravity of rail 14 (and these blades 16), so can bestow the turn right torsion of screw displacement (that is unwrapping wire) of this two spool 60.Owing to bestow above-mentioned two torsion of spool 60 simultaneously, opposite and the strength of action direction about equally (annotate: can by control in advance elastic force return the tensile strength of releasing part 50 or down rail 14 weight and reach), adding spool 60 is interted by double-screw bolt 33 to support its inner, cotton rope 18 pull the axis that axis that strength can make spool 60 departs from double-screw bolt 33 slightly, and allow the two 60, produce suitable frictional force between 33, make spool 60 can arbitrarily not rotate, in other words, this two cotton rope 18 is set around the length on the spool 60, and between last, following rail 12, the length of vertical section of 14 can be maintained at state at that time, that is to say that this two cotton rope 18 can will descend rail 12 liftings in predetermined altitude.
If the user catches the following rail 14 of holding shutter 10 and with its pulled down, then the pulling force because of cotton rope 18 returns the torsion (annotate: gap is twisted 33 aforementioned frictional force greater than spool 60 and spiral shell) of releasing part 50 much larger than elastic force, the screw displacement so this two spool 60 can be turned right synchronously, discharge the cotton rope 18 of two sides with the phase same rate, allow down rail 14 comply with staff pulling level, if the user decontrols down rail 14, then spool 60 can be replied aforementioned equilibrium state at once, makes down rail 14 be positioned height at that time.Otherwise, if the user will descend rail 14 to lift and hold up, then can alleviate the pulling force of cotton rope 18, elastic force is returned release part 50 torsion that provides to be enough to make the screw displacement of turning left synchronously of this two spool 60, furl the cotton rope 18 of two sides with the phase same rate, to descend rail 14 flatly up to draw and carry, decontrol down rail 14 until the user.
By above explanation as can be known, the blinds nest elevating mechanism that the utility model provides, can stablize stretching, extension, condensation and the location action of controlling shutter swimmingly, and it does not have the stay cord that exposes of traditional shutter, so it is attractive in appearance that the external form of shutter is comparatively simplified, and the accident that stay cord tangles the child can not take place.And, to compare with similar existing mechanism, structure of the present utility model is comparatively simplified, assembles comparatively convenient, so cost of production is lower.Moreover, when desire is adjusted the expanded area of shutter, hold up as long as directly rail under the curtain is down twisted or lifts, decontrol down rail again during to the hope height and get final product, very convenient in the operation.
Last mandatory declaration be, the following rail that the shutter elevating mechanism that the utility model provides also can select to be installed in shutter (relatively, the top side end of this two cotton rope is fixed in rail, the bottom side end is engaged in two spools in the utility model respectively), so, above-mentionedly make flowing mode and function still can normally be brought into play.
Again, in the utility model this two spools do not limit displacement in the same direction, in other words, even the hand of spiral difference that this two spiral shell is twisted, though make this two spool rotate towards same rotation direction, but simultaneously towards double-screw bolt the inner or simultaneously towards the axial displacement of double-screw bolt outer end, as long as in advance two cotton ropes all are engaged in the outer end (or being all the inner) of spool, the action that still can reach synchronous spiral, synchronous sloping line.
In addition, preceding running of taking off embodiment is the frictional force that uses 33 of spool 60 and double-screw bolts, makes be not subjected under external force gets involved, and spool 60 can be maintained fixed motionless.Only the utility model also can be set up a friction member in the accommodation space 32 of pedestal 30, and establish a friction part at the side face corresponding position ring of swing arm 40, make this friction close and touch this friction member with predetermined tightness, make 30 of swing arm 40 and pedestals have suitable frictional force, so also can bring into play identical functions.
