Background technique
Sitting traditional office chair office meeting before computer causes various diseases, and such as, disease of cervical vetebra, the root of disease of cervical vetebra is that after cervical intervertebral disk regression sex change, intervertebral discs 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 disease of cervical vetebra; 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 it is also proposed regulatory function, but often through mechanical structure manual tune, adjustment process is complicated, for more difficult the Ms that hand strength is less.
Summary of the invention
For the technical problem existed in prior art, the invention provides a kind of hydraulic system of Multifunctional computer chair, comprise manual hydraulic oil pump, diverter valve, manual hydraulic oil pump is connected with diverter valve by hydraulic pipe line, and described diverter valve drives oil cylinder with raise-lower hydraulic device, plate of stretching one's legs respectively by many hydraulic pipe lines and hydraulic driving oil cylinder of resting the head on is connected.
Further, described raise-lower hydraulic device is located at below the seat board of rotating base, and the described seat board back side is provided with manual hydraulic oil pump, plate of stretching one's legs drives oil cylinder.
Further, backrest rear is located at by described diverter valve, diverter valve has various switch, so as to control raise-lower hydraulic device, plate of stretching one's legs drives oil cylinder and headrest hydraulic driving oil cylinder action.
Further, headrest hydraulic driving oil cylinder is had after described backrest.
Further, plate of stretching one's legs drives hydraulic oil cylinder driving by plate of stretching one's legs.
The hydraulic system of Multifunctional computer chair of the present invention, manually hydraulic-pressure pump regulates, laborsaving easy, and compared with adopting the Computer chair of automatic hydraulic oil pump, structure is simple, low cost of manufacture.
