Abstract
The utility model discloses a headrest adjusting device of an office chair. The headrest adjusting device comprises a sliding rod, wherein a clamping groove is formed in the sliding rod; a sliding slot is arranged outside the sliding rod; two plastic modules, namely a spring fixing position and a spring supporting position, which are formed by plastic injection directly, are arranged on the sliding slot; a small slot is formed in the middle of the spring fixing position; a compression sheet spring can be arranged on the spring fixing position; the other end of the compression sheet spring is exactly stuck in the clamping groove of the sliding rod via the supporting position; and a pressing button is arranged on the compression sheet spring. The headrest adjusting device has the following beneficial effects that screws are fixed firmly without getting loose; compared with a traditional spring structure, the spring structure of the headrest adjusting device has better stability. And furthermore, the headrest adjusting device is simple in design, low in cost and easy to implement.
Description
Technical field
The utility model relates to field of furniture, in particular, relates to a kind of headrest adjusting device of office chair.
Background technology
The headrest adjusting device of current known office chair, is generally that head rest slide rail is set on head rest, and slide rail moves up and down in fixing locking device, then by lock screw or spring press, reaches the fixing effect of head rest.There is following problem in this design:
One, be screwed, inconvenience, easily loosening.
Two, conventional springs is fixedly pressed, with spring, easily from locking device, eject for a long time, and structural instability, there is very large drawback in design.
The problem existing in reality is exactly the great power that we constantly bring forth new ideas.
Summary of the invention
Technical purpose of the present utility model is to overcome in prior art, is screwed, and inconvenience, easily loosening; Spring is fixedly pressed, with spring, easily from locking device, ejects for a long time, and structural instability, there is very large drawback in design.Provide a kind of design ingenious, constitutionally stable office seating headrest adjusting device.
A headrest adjusting device for office chair, comprises sliding bar, has draw-in groove on sliding bar; Described sliding bar outside is sliding tray; On described sliding tray, there are directly two injection molded plastic modules, i.e. spring fixed bit and spring supporting position; In the middle of described spring fixed bit, have a sulculus; On described spring fixed bit, compressing tablet spring can be installed; Other one end of described compressing tablet spring is just stuck in the draw-in groove of sliding bar through support level; Above described compressing tablet spring, be provided with and press button.
When user upwards lifts sliding bar, because the direction of motion is consistent with draw-in groove and compressing tablet spring inclination angle, not needing to press button can complete; When user wants to allow sliding bar down sliding, need to first pin and press button, at this moment press pressing spring at fixing point, the strong point and press under button three's acting in conjunction and can bend, one of the contact of sliding bar draw-in groove can be upturned, first up lift gently sliding bar, after compressing tablet spring is completely separated with sliding bar groove, sliding bar can be toward lower slider.While sliding into ideal position, user unclamps and presses button, and compressing tablet spring sets back, and blocks sliding bar.
The beneficial effects of the utility model are screw fixing-stables, not loosening; To compare stability better with conventional springs structure.Simplicity of design, with low cost, easy to implement.
