Abstract
The utility model provides a pressure rod for a chair. The pressure rod comprises an outer large pipe, wherein a piston rod is fixed at one end of the outer large pipe, an outer pipe is nested with the other end of the outer large pipe, an annular support member is arranged between the outer large pipe and the outer pipe, the outer pipe is nested with an inner pipe, a sealing piston mechanism is arranged at one end of the inner pipe and connected with the piston rod, a valve body fine tuning driving mechanism is arranged at the other end of the inner pipe, and the diameter of the outer pipe is 29.0mm. According to the pressure rod for the chair, provided by the utility model, supporting force can be improved through the structure improvement; meanwhile, a spiral fine tuning structure for a start button is additionally arranged, and thus the outer pipe is prevented from being bent, the fine tuning is realized, and the comfort level and the applicability are improved.
Description
Technical field
The utility model relates to a kind of air pressure rod, the air pressure rod that a kind of lifting seat is used specifically.
Background technology
At present, after common product backrest post-tensioning is tested on market, because the large pipe in outside generally adopts working of plastics to support (POM material), very large pulling force cannot be born, buckling phenomenon can be produced, thereby cause the outer tube at the inner core position of air pressure rod also can produce bending, air pressure rod afunction.Meanwhile, the general control mode touch mode that adopts single button of the shake-up of inner tube valve body, easy and simple to handle, but be difficult to realize the function of finely tuning; Comfort level and applicability are not enough.
Utility model content
The shortcoming existing for prior art is with not enough, technical problem to be solved in the utility model is, a kind of seat air pressure rod is provided, by architecture advances, can increase support degree, increase the structure of start button spiral fine setting simultaneously, thereby avoid the appearance of outer tube buckling phenomenon, realize fine setting, increase comfort level and applicability.
For solving the problems of the technologies described above, technical solution adopted in the utility model is, a kind of seat air pressure rod is provided, and it comprises outside large pipe, outside large pipe one end fixed piston rod, the outside large nested outer tube of the pipe other end, between outside large pipe and outer tube, annular support member is set, the nested inner tube of outer tube, inner tube one end arranges packed-piston mechanism and connects piston rod, the inner tube other end arranges valve body fine setting driving mechanism, and described outer tube diameter is 29.0mm.
Above-mentioned seat air pressure rod, its valve body fine setting driving mechanism comprises the valve body that is fixed on inner tube end, and valve body outer end arranges valve body switch, and valve body switch connects start button, and Height Adjustment screw is set on start button.
Above-mentioned seat air pressure rod, its packed-piston mechanism comprises the piston that is fixed on piston rod end, and piston both sides arrange supporting bead, and medial support packing ring is by open type supporting pad and protruding supporting pad support.
Above-mentioned seat air pressure rod, arranges gas seal between its open type supporting pad and protruding supporting pad.
Above-mentioned seat air pressure rod, its outside large tube end welding outer tube supporting pad, outer tube supporting pad is by clip fixed piston boom end and bearing, and bearing one side arranges shock-absorbing buffer pad.
The utlity model has following advantage and useful technique effect:
1, seat air pressure rod of the present utility model, pass through architecture advances, outer tube caliber size is improved to Φ 29.0 * 3.0T by original Φ 28.0 * 2.0T, Φ 28.0 * 2.5T can significantly increase support degree, and the post-tensioning proof strength of backrest is significantly strengthened.
2, seat air pressure rod of the present utility model, increases the structure that start button spiral is finely tuned, and realizes fine setting, increases comfort level and applicability.
3, seat air pressure rod of the present utility model, decoration structure features simple design, reasonable, production cost is lower, is convenient to marketing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In above-mentioned figure:
