Description
Technical field
The utility model is related to office chair apparatus field, more particularly to a kind of office chair.
Background technology
Office chair because it is simple to operate, comfortableness is strong the features such as be highly suitable for the occasions such as office and operating room and use, have
Beneficial to human eye and vertebra health, it is beneficial to improve study and work efficiency, also has part family to pursue comfort level, be placed on study and do
Minister uses, generally also one kind of computer chair.The cylinder assembly of office chair is the Lift Part of office chair, the liter for office chair
Drop, can make office chair regulation to most comfortable position, while being also the important stable part of office chair, whether office chair is comfortable
It is stable largely to be influenceed by cylinder assembly.
Stable and support work is mainly played in its effect of cylinder sleeve in cylinder assembly during cylinder is lifted
With making office chair be unlikely to deflection in use, existing cylinder assembly has been able to reach rotation and the liter of office chair
Drop is acted on, and cylinder sleeve can also play stabilization and the supporting role of office chair, but in long-term use, in sliding friction
In the presence of power, cylinder sleeve long term wear reverses office along with office chair user can shake in use
Chair etc. is acted, and cylinder sleeve is in the state of a discontinuity for a long time, so as to exacerbate the abrasion dynamics of cylinder sleeve;
In addition, its end cap end face structure of the plastic cement bushing of prior art is excessively simple, coarse, it is in axial restraint cylinder, bushing end
The cooperation of the inner headed face of face and cylinder sleeve is not accurate enough, causes office chair stationarity and comfortableness variation etc. in use
Phenomenon occurs.Therefore, change is made in the structure of cylinder sleeve, the service life of office chair is improved, exactly inventor will solve
Certainly the problem of.
Utility model content
In order to solve the problem of office chair service life caused by cylinder assembly fault of construction of the prior art is not long,
The utility model provides a kind of office chair.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme:
A kind of office chair, including cylinder assembly, the seat that is connected with cylinder assembly upper end and the lower end with cylinder assembly
The chair leg of connection, wherein, cylinder assembly includes cylinder, plastic cement bushing and cylinder sleeve, and cylinder sleeve includes coaxial set
Inner barrel and outer cylinder body, the cavity that cross section is annular is formed between inner barrel and outer cylinder body, under inner barrel and outer cylinder body
End be welded as a whole by pad, the upper end of inner barrel and outer cylinder body by plastic cement bushing axially position cylinder, plastic cement bushing
Inner face is provided with the positioning boss being engaged with the inner headed face of cylinder inner barrel.
The single layer structure of cylinder sleeve of the prior art is changed into the binocular structure of cylinder inner barrel and outer cylinder body, than
Single layer structure is more firm, and is designed between cylinder sleeve upper end inner barrel and outer cylinder body for the cavity of annular, cylinder jacket
Cylinder needs phosphorating treatment in process of production, the annulus that the water produced during phosphorating treatment can be between inner barrel and outer cylinder body
Shape cavity is discharged.
The end face of plastic cement bushing of the prior art is excessively simple, coarse, its in axial restraint cylinder, bush end face with
Cooperation between cylinder sleeve is not accurate enough, causes office chair to occur that stationarity and comfortableness variation etc. are existing in use
As, the utility model sets positioning boss by the inner face in plastic cement bushing, makes bush end face and cylinder sleeve precision-fit,
Add the stationarity and comfortableness of office chair.
The utility model passes through connector axial restraint cylinder at the lower end pad of the inner barrel and outer cylinder body.
The cylinder that the utility model is provided includes cylinder core, cylinder barrel, piston, piston rod and control valve;The utility model
The upper end of described whole cylinder assembly connects the seat of office chair by connector, and lower end is connected to office chair by connector
Chair leg.
The cylinder assembly for the office chair that the utility model is provided, compared with existing cylinder assembly, the individual layer knot of cylinder sleeve
Structure is changed into the binocular structure of cylinder inner barrel and outer cylinder body, more firm than single layer structure, and cylinder sleeve upper end inner cylinder
Annular cavity design between body and outer cylinder body can be such that the water in sleeve production process discharges easily;Plastic cement bushing inner face
Positioning boss design, make bush end face and cylinder sleeve precision-fit, add the stationarity and comfortableness of office chair.
