Four, description of drawings.
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is a T-shaped elevating lever described in the utility model, gear regulating spring, cramp, garden pin assembling front view;
Fig. 3 is a T-shaped elevating lever described in the utility model, gear regulating spring, cramp, garden pin assembling side elevation;
Fig. 4 is a garden described in the utility model tube column structural representation.
Five, the specific embodiment.
The utility model is a kind of button-free adjustable armrest of revolving chair, comprises garden tube column 1, links iron plate 6, handrail plastic casing 5 wherein is welded with little garden sheet 15 in the garden tube column 1, link iron plate 16 by connecting bolt 17, little garden sheet 15 and garden tube column 1 fastening linking, garden tube column 1 links with 5 activities of handrail plastic casing, it is characterized in that also comprising tee T elevating lever 2, gear regulating spring 3, guide spring 6, guide runner 7, garden pin 8, promote controller 9, gear regulating block 10.Gear regulating spring 3 one ends have passed through spring groove 2-1, cramp 4, control hole 2-2 is fixed on the tee T elevating lever 2, the other end and 8 activities of garden pin link and can move with the slip of garden pin 8, sliding tray 2-3 is arranged on the tee T elevating lever 2, tee T elevating lever 2 is installed in the lifting groove 10-2 of gear regulating block 10, and can in lifting groove 10-2, move up and down, garden pin 8 is installed in the sliding tray 2-3 and can slides in sliding tray 2-3, link by sliding tray 2-3 and 2 activities of tee T elevating lever simultaneously, the gear groove 10-3 that has number not wait on the gear regulating block 10, garden pin 8 links with gear groove 10-3 activity, promoting on the controller 9 has and gear groove 10-3 similar number and corresponding control flume 9-1, promoting controller 9 links with 10 activities of gear regulating block, guide runner 7, guide spring 6 links with gathering sill 10-1 activity.Have control hole 2-2 on the tee T elevating lever 2, cramp 4 be installed in the control hole 2-2 and with gear regulating spring 3 firm linking, have waist hole 1-1 on the garden tube column 1, hole, garden 1-2, have rotation spring eye 10-4 on the gear regulating block 10, dowel hole 10-5, tee T elevating lever 2 is by hanging face bolt 11 and handrail plastic casing 5 fastening linking, gear regulating block 10 is by being installed on the alignment pin 12 in the dowel hole 10-5, be installed on the rotation spring 14 in the rotation spring eye 10-4, steel ball 13 links with 1 activity of garden tube column.
During use, upwards spur handrail shell 5, drive tee T elevating lever 2 to rising, thereby garden pin 8 is skidded off from gear groove 10-3, enter among the control flume 9-1, drive lifting controller 9 and be moved upward to the top, tee T elevating lever 2 can't continue to rise at this moment, stops to draw high, tee T elevating lever 2 falls after rise, because the effect of gear regulating spring 3, garden pin 8 skid off from the control flume 9-1 that promotes controller 9 and enter among the last one grade gear groove 10-3, simultaneously because the effect of stage clip 18, promote controller and fall back to original position, like this repeatable operation, from deep low gear be adjusted to the most high-grade be adjusted to the extreme higher position after, garden pin 8 will fall after rise by lifting groove 10-2 and contact to the bottom and with guide runner 7, continue to regulate tee T elevating lever 2 downwards, because the guide effect of guide runner 7, garden pin 8 skids off from lifting groove 10-2, enters the deep low gear of gear groove 10-3, simultaneously because the effect of guide spring 6, guide runner 7 homings are are so gone round and begun again, thereby reach the purpose of regulation stall.
