The specific embodiment
As shown in Figure 1, the utility model heavy curtain adjusting device 10 is for being arranged at an end of heavy curtain 22 central siphons 20.
As shown in Figure 2, the utility model heavy curtain adjusting device 10 comprises outer tube 11, bearing 12, adjusts axostylus axostyle 13, backstay 14, fixed structure 40 and stator 50.
Adjusting axostylus axostyle 13 1 ends is provided with and passes outer tube 11 and turn round coil spring 21 with central siphon 20 inside and connect the connecting rod of establishing 131, its other end is provided with and protrudes from the holding rod 132 of adjusting axostylus axostyle 13 end faces, and be provided with the slide rail 133 of inserting in holding rod 132 1 end places, and be arranged with two fixing holes 134 in the end face of holding rod 132 ends for backstay 14.
Backstay 14 bottoms form correspondence and are embedded at the oblique cone shape guiding face 141 in the oblique cone shape locating slot 112 on the outer tube 11 inner edge walls, are provided with flexible member 15 between backstay 141 and the holding rod 132.Pull on the end face of holding rod 132 in the one end top of flexible member 15, its other end is placed in backstay 14 inside.
As shown in Figure 3, Figure 4, during assembling, the utility model is arranged at an end of heavy curtain central siphon 20, and makes the connecting rod 131 of adjusting axostylus axostyle 13 by lock member 30 and turn round coil spring 21 lockings, order is adjusted axostylus axostyle 13 and is turned round coil spring 21 synchronization actions.
When coil spring 21 is turned round in the desire packing, backstay 14 is moved to guiding face 141 directions, guiding face 141 owing to backstay 14 during rotation is corresponding states with oblique cone shape locating slot 112, therefore backstay 14 is subjected to the guiding of guiding face 141 and moves to holding rod 132 directions, and the flexible member 15 that makes 132 of backstay 14 and holding rods is compressed and produces the active force of pre-storage.
When guiding face 141 turns to oblique cone shape locating slot 112 summits and enters in the next oblique cone shape locating slot 112, backstay 14 is under flexible member 15 elastic restoring force effects, to oblique cone shape locating slot 112 inner pushing tows, excessive and cause resetting of backstay 14 in order to do the torsion that can prevent to turn round coil spring 21, make backstay 14 just win and rotate by single direction.
Because outer tube 11 and 13 of axostylus axostyles of adjustment are provided with bearing 12, therefore, adjustment axostylus axostyle 13 is freely rotated in outer tube 11, turn round coil spring 21 so as to driving; Because turning round coil spring 21 1 ends is movable end, so when coil spring 21 is turned round in packing, make movable end be able to move to adjusting axostylus axostyle 13 directions, so, the active force of turning round 13 pre-storages of coil spring is increased, and then reach the locating effect of adjusting axostylus axostyle 13, and turn round coil spring 21 involutions in order to do preventing, make the active force of turning round the pre-storage of coil spring 21 maintenances.
As shown in Figure 1 and Figure 2, after turning round coil spring 21 and being subjected to packing to produce suitable pre-storage active force, utilize fixed structure 40 that the utility model is placed on the stator 50, in order to do the utility model being hung on the metope by stator 50.
Fixed structure 40 comprises the locating piece of adjusting ring 411 and being made of two left and right spacers that fasten relatively.Adjust ring 41 and have at least one and lack 411, and be provided with for adjusting and encircle the ring-type slide rail 412 of setting slippage in left and right spacer 42,43 in adjusting ring 41; Adjust ring 41 periphery walls and be provided with several so that the projection of adjusting 413.Corresponding respectively being provided with for adjusting several embeddings that axostylus axostyle 13 grip parts 132 and backstay 14 set groove 421,431 of pulling on the left and right spacer 42,43, right spacer 43 is provided with limited block 432.Fixed structure 50 utilizes bolt 60 to be locked on the stator 50.
Stator 50 is provided with scalariform draw-in groove 51 and several draw-in grooves 52 corresponding and right spacer 43 upper limit position blocks 432 clips that confession is adjacent.By right spacer 43 upper limit position blocks 432 clips on stator 50 in the draw-in groove 52, in order to do making a left side, right spacer 42, the embedding groove 421 of pulling on 43,431 is corresponding with scalariform draw-in groove 51, so as to making holding rod 132 be embedded at a left side, right spacer 42,43 embedding slot 421,431 and the scalariform draw-in groove 51 of stator 50 in, and make the oblique cone shape locating slot 112 that is broken away from outer tube 11 of backstay 14 guiding faces 141, in order to do making outer tube 11 be able to drive and carry out furling of heavy curtain 22, and make and turn round that coil spring 21 remains in the position of previous setting and the action of not disturbing central siphon 20 in the central siphon 20 by central siphon 20.
In addition, the difference of stator 50 visual locking metopes and do angle displacement simultaneously, makes and adjusts axostylus axostyle 13 and be fixed on the stator 50, and can keep smooth degree that central siphon 20 rotates and the pre-storage active force of turning round coil spring 21.
In addition, as Fig. 5, shown in Figure 6, also can be provided with at least one embedding groove 113 of pulling in outer tube 11 storage tanks 111 inwall peripheries; Be convexly equipped with corresponding and embedding on outer tube 11 embedding embedding in the groove 113 projection 142 of pulling of pulling of pulling in backstay 14 bottoms.Pull in groove 113 is pulled in the embedding of outer tube 11 by backstay 14 bottom embeddings projection 142 embeddings of pulling, make and adjust axostylus axostyle 13 and rotate in being able in outer tube 11.
As shown in Figure 6, the utility model can further be adjusted by adjusting lever group 70, and adjusting lever group 70 comprises fixed bar 71 and holding rod 72.
Fixed bar 71 corresponding adjustment axostylus axostyle 13 holding rods 132 end face fixing holes 134 form two fixedly nose bars 711.
Form the portion of pulling 721 of revolving in order to clip fixed bar 71 on the holding rod 72, and make holding rod 72 be able to turn on fixed bar 71, holding rod 72 extensions are provided with lever 722.
Whereby, when fixing nose bar 711 corresponding to after adjusting axostylus axostyle 13 holding rods 132 end face fixing holes 134, rotate by lever 722, and drive and adjust axostylus axostyle 13 and rotate.When holding rod 72 makes holding rod 72 tops be held in backstay 14 according to fixed bar 71 turns, can be by holding rod 72 with backstay 14 jack-up, order is adjusted axostylus axostyle 13 and be able to carry out reciprocal rotation on outer tube 11, recover to remain in optimum state in order to do turning round coil spring 21 in order to loosen, make the elasticity of turning round coil spring 21.
