The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5,35 is back, putting head bracket 27 is connected with seat back frame crossbeam 36 in the back frame 6, putting an adjustment means comprises and puts head bracket 27, it is connected by the grooved bore of lifting shaft 45 with an end of putting headstock anchorage clip 25, the described other end of putting headstock anchorage clip 25 also has grooved bore, this grooved bore links to each other with the medicated pillow fork-shaped link 23 that has axle, put headstock anchorage clip middle part one eccentric lock stopping bar 26 is arranged, the one end be positioned at the clamp nut 37 of putting headstock anchorage clip bottom and fix, eccentric lock stopping bar 26 tops with put headstock handle 24 and be connected with pin 38, simultaneously both again with screw pin 44 with put headstock anchorage clip and link to each other, wherein, the macropore of the eccentric lock stopping bar that screw pin passes, purpose is given active space of eccentric lock stopping bar.
Adjustment process:
1, handle compresses (the diagram direction of arrow) pin and turns to peak around screw pin, the eccentric lock stopping bar is carried on the whole, two grooves putting headstock anchorage clip are clamped, simultaneously, hold tightly with lifting shaft and with the axle of medicated pillow fork-shaped link in two holes that communicate with groove, make and put the headstock and press from both sides with medicated pillow fork-shaped link stiffly admittedly, reach the purpose of locking.
2, handle is unclamped, the eccentric lock stopping bar moves down, and two grooves putting headstock anchorage clip open simultaneously, and also unclamp axle in the hole that communicates with groove, puts headstock anchorage clip and medicated pillow fork-shaped link free adjustment but make.
Chair has chassis 10, it holds a frame, seat cushion 8, and the underframe seat is by the hexagonal spiral shell, and nut shim is connected with supporting box 17,16 is rubber cushion, attic base is connected with the attic base connecting axle with the underframe seat, and seat chassis connecting axle is upper and lower all screw thread, during installation, with jackscrew 20 the attic base connecting axle is fixed earlier, reuse packing ring, nut are fastened on axle with attic base, and attic base connecting axle bottom links to each other with the underframe seat, but can not fix with packing ring, nut.
Arm-rest frame 4,6 is connected with rivet by Ω shape connector, and when regulating seat back frame, arm-rest frame can move together.The adjusting device that makes 360 ° of seat support revolutions is housed on the underframe seat.
Adjusting device has 360 ° of postrotational retaining mechanisms of an adjustment chair, this mechanism is: two holes that connect are arranged on underframe seat 14, one of them macropore passes chassis connecting axle 19, another aperture is worn two latch 13 and a locking rod 12, one end of locking rod is fixing with packing ring, nut 18, and the other end links to each other with locking handle 11 by pin 39, and a hole is arranged in the middle of the locking plate washer 38, be through on the locking rod, between latch and locking handle.The effect of locking plate washer is to prevent that locking handle and latch from directly rubbing, and prevents that handle from moving round about.
Adjustment process
1, be illustrated as locking state, at this moment, two latch are held the attic base connecting axle tightly by the cambered surface of self, because attic base connecting axle upper end is fastening with the chair attic base, so chair is stiff.
2, extremely in alignment along direction of arrow driving handle with locking rod, because bca on the locking rod unclamps so locking rod can connect attic base axle, make axle be with 360 ° of seat support revolutions.
Fig. 5 is a kind of backrest regulation scheme: backrest 35, seat all are connected with axle I41 by connector among Fig. 5, hinged through axle II42 and stick 31 again, the welding spring fastenings is connected another termination one spring on the present frame with the tooth plate spring, this spring other end and spring fastenings join, spring brace and stick welding.
Principles of Regulation: 1 upwards carries stick, emboss pit on the emboss pit and tooth plate is broken away from this moment give a hard push backwards that (backrest rotates around axle I41 backrest, the spring elongation) to required angle, unclamps joystick lever, the tongue and groove on the stick is gone in the emboss pit of tooth plate, at this moment position of back is a lockable, 2 ', upwards carry stick, tongue and groove on the bar and the emboss pit on the tooth plate break away from, since the pulling force of spring, backrest nature pop into position.
Fig. 6 a, b, backrest 35, seat all are connected with axle I41 by connector among the figure, hinged through axle II42 and air spring 52 again, welding one fixed mount 48 on the seat frame, regulating handle 46 afterbodys have axle, outer shaft sleeve one small sleeve 49, they are fixing in order to pin 50, small sleeve and adjustable plate welding connect female 51 and are tightened on the air spring 52, link to each other with fixed mount with two hex bolts 33 simultaneously.
Principles of Regulation:
1, upwards move regulating handle, make small sleeve, adjustable plate rotates with the axle of regulating handle, and adjustable plate compresses the locking button on the air spring, at this moment pushes hard backrest to the optional position, release handle, and the air spring self-locking locks position of back simultaneously.
2, upwards move regulating handle, make adjustable plate compress the locking button of air spring, the air spring resilience is extended, backrest nature homing.
