Abstract
This utility model belongs to office chair field, discloses a kind of cylinder assembly of office chair.The cylinder assembly includes that cylinder, cylinder sleeve and plastic cement bushing, cylinder sleeve upper end are axially fixed in cylinder in cylinder sleeve by plastic cement bushing, and cylinder sleeve lower end is by pad and connector axial restraint cylinder；Cylinder sleeve includes that the inner barrel and outer cylinder body of coaxial setting, inner barrel upper end arrange the flange for encasing outer cylinder body upper end, and outer cylinder body lower end is welded as a whole with inner barrel.The cylinder sleeve of the cylinder assembly includes inner barrel and outer cylinder body, the setting of this binocular structure increased the steadiness of cylinder sleeve, the service life of office chair can be extended, osculum is opened up simultaneously on inner barrel flange, phosphatization product water cannot be discharged in process to solve the problems, such as binocular structure, be achieved the commercial production of the cylinder assembly.
Description
Technical field
This utility model is related to office chair field, more particularly to a kind of cylinder assembly of office chair.
Background technology
The cylinder assembly of office chair is the Lift Part of office chair, for the lifting of office chair, adjusts can office chair
Most comfortable position is arrived, while being also the important stable part of office chair, whether office chair is comfortably stable to be received to a great extent
The impact of cylinder assembly.
Cylinder sleeve in cylinder assembly its act on and mainly play load-bearing and stable effect in the process of cylinder lifting,
When using office chair steadily firmly, existing cylinder assembly has been able to reach the rotation of office chair and lift action, cylinder
Sleeve can also play the firm effect of office chair, but in long-term use, in the presence of force of sliding friction, cylinder jacket
Cylinder long term wear, reverses the actions such as office chair along with office chair user can be shaken in use, makes cylinder jacket
The tube length phase is in the state of a discontinuity, so as to exacerbate the abrasion dynamics of cylinder sleeve, therefore, in cylinder sleeve
Change is made in structure, so as to improve the service life of office chair, exactly inventor's problem to be solved.
Utility model content
In order to solve the problems, such as cylinder assembly fault of construction of the prior art and caused office chair service life is not long,
This utility model provides a kind of cylinder assembly of office chair.
In order to solve above-mentioned technical problem, this utility model is employed the following technical solutions：
A kind of cylinder assembly of office chair, including cylinder, cylinder sleeve and plastic cement bushing, cylinder sleeve upper end passes through plastic cement
Bushing is axially fixed in cylinder in cylinder sleeve, and cylinder sleeve lower end is by pad and connector axial restraint cylinder；Cylinder
Sleeve includes that the inner barrel and outer cylinder body of coaxial setting, inner barrel upper end arrange the flange for encasing outer cylinder body upper end, outer cylinder body
Lower end is welded as a whole with inner barrel.
This utility model by the structure setting of the cylinder sleeve in cylinder assembly into binocular structure, and turn over by inner core upper end
While encasing outer tube upper end, outer tube lower end is finally converged and extended in inner core lower end and outer tube lower end, and this kind of structure makes cylinder assembly
More firmly, the service life of office chair can be extended.
Preferably, the cylinder sleeve inner core upper end flange that this utility model is provided along the circumferential direction uniformly opens up several rows
Water hole, because cylinder sleeve needs bonderizing during post-production, this operation can produce water, therefore arrange on inner core flange
Osculum, facilitates draining.
The cylinder that this utility model is provided includes the parts such as cylinder core, cylinder barrel, piston, piston rod and control valve.
The cylinder assembly that this utility model is provided, its upper end connect the seat of office chair by connector, and lower end is by connecting
Fitting is connected to the chair leg of office chair.
Compared with prior art, the cylinder sleeve that this utility model is provided includes inner core and outer tube, this binocular structure
The steadiness that increased cylinder sleeve is set, and the service life of office chair can be extended, while draining is opened up on inner core flange
Hole, phosphatization product water cannot be discharged in process to solve the problems, such as double-barrel structure, obtain the commercial production of the cylinder assembly
To realize.
Description of the drawings
Fig. 1 is the profile of office chair cylinder assembly provided by the utility model.
Specific embodiment
