Description
Technical field
The invention belongs to field of office furniture, especially belong to office healthcare product, specifically a kind of multi-purpose computer chair backrest adjusting mechanism.
Background technology
Sitting traditional office chair office meeting before computer causes various diseases, and such as, cervical spondylopathy, the root of cervical spondylopathy is that after cervical intervertebral disk regression sex change, interverbebral disc loosens, then pressuring neural root, spinal cord or vertebral artery and the various symptoms caused.Sitting posture bad for a long time or before resting on computer for a long time, the most easily causes the fatigue of neck flesh, causes neck and shoulder ache, item muscle spasmus, even occur having a dizzy spell; In the course of time, after growing up, degeneration of cervical intervertebral disc certainly will be there is prematurely, cause cervical spondylopathy; Lumbar vertebra disease, due to long-term sitting, or the sitting posture had is bad, or always fixes a posture and make lumbar soft tissue be in tension state for a long time, soft tissue ischemic, and produces lumbar muscle strain; Coccyx is injured, and the symptom of coccyx pain comprises near buttocks coccyx tender point or skelagia phenomenon, and scope comprises coccyx, levator ani and soft tissue etc. around.Permanent abnormal sitting posture is true, and compressing coccygeal nerve, can cause coccyx injured and pain; DOMS, hundreds of millions cells in human body will lean on the transport of blood to complete its metabolic function, and sitting can make to take oxygen blood flow volume in body and reduce, and partial pressure of oxygen reduces and takes carbon dioxide blood flow volume and increases, partial pressure of carbon dioxide raises, and causes DOMS, stiff, atrophy.
Existing office chair also can regulate the position of backrest, but major part all by backrest inclination, can only make user be in semi-lying position, seldom have and backrest can be adjusted to bed flat position.
Summary of the invention
For the technical problem existed in prior art, the invention provides a kind of multi-purpose computer chair backrest adjusting mechanism, comprise: rotating base, backup plate, handrail, plate of stretching one's legs, pedal and hydraulic system, described backrest and seat board hinged can 90 ° rotate and locate arbitrarily, it there is supporting leg, supporting leg has arc support rod.
Further, also comprise angle adjustment rule, angle adjustment rule are hinged on the hinge of described backrest and seat board by middle part pole, and one side has chute, can slide at the ledge of seat board rear end column.
Further, when sitting up straight or partly couching state, the strut end that described angle adjustment advises one end bayonet lock and hole and supporting leg is hinged; When lying status, it is made to be separated with strut by rotating bayonet lock, and by latch and curved support club head hinge.
Further, there is arc-shaped limit ratchet described angle adjustment rule inside, click-fit on itself and seat board column realizes locating, backrest handle is articulated with angle adjustment rule shell, its cam type end controls the separating action of spacing ratchet and ratchet, during backrest handle return, elastic ring makes arc-shaped limit ratchet engage with ratchet.
Multi-purpose computer chair backrest adjusting mechanism of the present invention can realize lying low, semi-lying, the various states such as to sit up straight, and adjustment process is simple and convenient, meets the various sitting posture requirements of user.

Detailed description of the invention
below in conjunction with accompanying drawing, the invention will be further described.
As shown in figures 1 to 6, the multi-purpose chair of prevention and therapy computer office disease of the present invention, have sit up straight office, the rest that couches, traction stretch function.Concrete structure comprises: rotating base 1, backup plate 2, handrail 3, plate 4 of stretching one's legs, pedal 5 and hydraulic system.
Hydraulic system comprises manual hydraulic oil pump 6, flow divider 7, and manual hydraulic oil pump 6 is connected with flow divider 7 by fluid pressure line, and flow divider 7 drives oil cylinder 9 with raise-lower hydraulic device 8, plate of stretching one's legs respectively by many fluid pressure lines and hydraulic driving oil cylinder 10 of resting the head on is connected.
Described rotating base 1 comprises raise-lower hydraulic device 8, universal wheel 11 and seat board 12; Seat board 12 is located at the top of raise-lower hydraulic device 8, the described seat board back side is provided with manual hydraulic oil pump 6, plate of stretching one's legs drives oil cylinder 9, plate 4 of stretching one's legs is located at plate of stretching one's legs and is driven on the piston of oil cylinder 9, plate of stretching one's legs drives below oil cylinder 9 and is provided with oil cylinder bracket 13, oil cylinder holds up lever 14 and is located at below oil cylinder bracket 13, oil cylinder holds up lever 14 one end and is connected in oil cylinder bracket 13 by hinge, oil cylinder holds up in the middle part of lever 14 and is connected in seat board 12 by hinge, when backrest is in level, by bracket leverage, the plate 4 that can make to stretch one's legs upwards lifts and makes itself and seat board 12 be in same plane.Pedal 5 is connected with plate 4 of stretching one's legs by expansion link 15, and expansion link 15 folds by hinge.
Described backrest 2 and seat board 12 hinged can 90 ° rotate and locate arbitrarily, it there is supporting leg 16, supporting leg 16 there is arc support rod 17, backrest 2 rear is located at by flow divider 7, flow divider 7 has various switch, so as to control raise-lower hydraulic device 8, plate of stretching one's legs drives oil cylinder 9 and headrest hydraulic driving oil cylinder 10 action; There is headrest hydraulic driving oil cylinder 10 after backrest, headrest has cervical spine tractor 18 and lumbar tractor 19, move with headrest one under headrest hydraulic driving oil cylinder 10 drives.Have the different parts of tightening health during flexible bundle band (not shown) tractive in the oxter height of backrest, stomach height, hip height system, backup plate is provided with flexible bundle band location division 20.
Angle adjustment rule 21 are hinged on described backrest 2 with on the hinge of seat board 12 by middle part pole 22, one side has chute, can slide at the ledge of seat board rear end column, when sitting up straight or partly couching state, one end lock mechanism (bayonet lock 23+ hole) is hinged with strut 24 end of supporting leg; When lying status, it is made to be separated with strut 24 by rotating bayonet lock 23, and with latch and arc support rod 17 head hinge, angle adjustment advises 21 inside arc-shaped limit ratchet 25, it coordinates with the ratchet 26 on seat board column and realizes locating, and backrest handle 27 is articulated with angle adjustment rule shell, and its cam type end controls the separating action of spacing ratchet and ratchet, during handle return, elastic ring 28 makes arc-shaped limit ratchet 25 engage with ratchet 26.
