Description
Technical field
It the utility model is related to a kind of foot-operated, more particularly to a kind of chair is foot-operated.
Background technology
Existing bar chair is generally provided with circle and steps on ring, is used for leg rest.Wine is fixed in order to which circle is stepped on into ring
It is general that ring is stepped on the cooperation of the taper collar to realize using circle on the main shaft of chair.Specifically, set on the inside of circular ring
There is cross frame, the center collar is provided with the centre of cross frame, be the bevelled endoporus of tool on the inside of the collar of center, and it is interior
There is screw thread hole upper end；And the upper end of the taper collar is provided with external screw thread, the lower end of the taper collar offers at least two grooves, will
It is divided into some compressible fins, and square hole is offered on every piece of fin, and it is suitable that size is sequentially placed in the inner side of its square hole
Soft rubber piece and inclined-plane briquetting；When circle, which steps on ring, to be rotated down, drive the center collar inclined-plane downwards with the taper collar
It is closely sealed, inclined-plane briquetting can be forced inwardly to compress soft rubber piece, it is closely pasted and on main shaft, so as to reach the mesh being fixed
's.This fit system, by the way of averagely being pressed using whole face, the taper collar will not be caused to damage, it can be extended and use the longevity
Life, meanwhile, main shaft is uniformly compressed by multi-disc soft rubber piece, main shaft will not be damaged.
But this design, because parts are more, especially the large number of and volume of soft rubber piece and inclined-plane briquetting is very
It is small, it is extremely difficult in installation process, waste time and energy；And in use, soft rubber piece and inclined-plane briquetting are due to being independent
Part, easily come off or deform, so as to influence to use.
The content of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of the foot-operated of chair, by that will bore
Collar integrated injection molding is spent, U-channel is offered on fin, forms compressible friction plate, while fin medial surface
Both sides protrude to form perpendicular rib, closely sealed with the taper collar under drive center ring when circle, which steps on ring, to be rotated down, and can force and rub
The close patch and on main shaft of pad and perpendicular rib, so as to reach the purpose being fixed, by the way of averagely being pressed using whole face, not only
Main shaft and the taper collar will not be caused to damage, the parts of combination are less, easy for installation, due to friction plate and perpendicular rib and taper
The collar is integrally formed, loss difficult for drop-off.
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
A kind of chair is ridden, including circle steps on ring and the integrated injection molding taper collar, and the circle is stepped on the inside of ring and set
Be equipped with support, be provided with the center collar at the carriage center, be columned endoporus on the inside of the center collar, the endoporus and
Circle steps on ring with one heart and upper end has screw thread；The taper collar upper end is provided with and the close-fitting outer spiral shell of endoporus threaded upper ends
Line, the lower end of the taper collar offer at least two grooves, form some fins that can be compressed, U is offered on the fin
Shape groove, forms compressible friction plate, and the both sides of the fin medial surface protrude to form perpendicular rib.By the way that the taper collar is integral
Injection molding, U-channel is offered on fin, form compressible friction plate, while the both sides protrusion shape of fin medial surface
It is closely sealed with the taper collar under drive center ring when circle, which steps on ring, to be rotated down into perpendicular rib, friction plate and perpendicular rib can be forced
Close patch and on main shaft,, not only will not be to main shaft by the way of averagely being pressed using whole face so as to reach the purpose being fixed
Cause to damage with the taper collar, the parts of combination are less, easy for installation, due to friction plate and perpendicular rib and taper collar one into
Type, loss difficult for drop-off.
Preferably, the lower end outside of the fin is towards contract.This design, ensureing what fin upper end was compressed
Under the premise of, reduce the use of material, save cost.
Preferably, the taper collar is integrated the working of plastics of injection molding.
Compared with prior art, the beneficial effects of the invention are as follows：By by taper collar integrated injection molding, on fin
U-channel is offered, forms compressible friction plate, while the both sides of fin medial surface protrude to form perpendicular rib, when circle steps on ring
When being rotated down, drive closely sealed with the taper collar under center ring, friction plate and perpendicular rib closely patch and on main shaft can be forced,
So as to reach the purpose being fixed, by the way of using whole face averagely pressing, not only main shaft and the taper collar will not be caused to damage
Bad, the parts of combination are less, easy for installation, because friction plate and perpendicular rib are integrally formed with the taper collar, loss difficult for drop-off.
