Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that a kind of pneumatic office chair, to realize the height adjustable of pneumatic office chair armrest and simple in construction, easy to operate.
For achieving the above object, the present invention proposes following technical scheme: a kind of pneumatic office chair, it includes pedestal and seat support, described seat support includes supporter and the chair back body being connected on described supporter, the both sides of described supporter are connected by arrangement for adjusting height the handrail body of rod, described height adjustable regulating device includes the multiple sleeves being arranged on described supporter both sides, and it is arranged on the actuator in described sleeve, the drive hole run through is formed in described actuator, the lower end of the described handrail body of rod is provided with sliding part, in described sliding part is socketed in described drive hole and vertically move in described drive hole, the side of described actuator connects source of the gas, described source of the gas communicates with described drive hole, and
The end of described source of the gas is provided with press section, and pressing press section is injected air in drive hole, driven described sliding part to move up and down in described drive hole, the outer surface of described sliding part is set with bumper ring (29).
Preferably, described bumper ring uses O RunddichtringO.
It is provided with damping piece on described sliding part.
The top of described chair back body is provided with neckpillow.
The middle part of described neckpillow is provided with arc-shaped recess portion.
Described neckpillow is semi-cylindrical.
The middle part of described chair back body is plugged with back cushion.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention regulates height and the level angle of office chair in the way of pneumatic, simple to operate, it is simple to control.
2, the present invention installs damping piece on arrangement for adjusting height additional, it is possible to the impulsive force that the sliding part on buffering handrail moves up and down so that sliding part moves up and down and can control.
3, the arrangement for adjusting height simple in construction of the present invention, structure configure upper the most extremely compact and easy to operate.
