Description

The anti-deflection office seating of flat turn and lifting integral type

Technical field

The utility model relates to a kind of improvement of lifting seat of the use of handling official business, and belongs to office furniture technical field, the anti-deflection office seating of specifically a kind of flat turn and lifting integral type.

Background technology

Rotating lifting seat is conventional a kind of seat for office, and this seat is owing to rotating, thus turnover direction or user towards can arbitrarily adjusting without stand up in the situation that, use flexibly, convenient, comfortable, quite liked. The structure of the rotation lifting seat using at present, mostly comprise base, backrest, handrail, screw rod, barrel and the underframe with universal rolling wheel, the upper end of screw rod is vertically fixed on the diapire middle part of base, the lower end of screw rod screws in barrel, the lower end of barrel is vertically fixed on the center of underframe, underframe is made up of 5 Radiation cross bars, is equipped with universal rolling wheel in the outer end of cross bar. The deficiency of this rotation lifting seat is: the one, because the diapire middle part at base only has a screw rod to support, load-bearing area is little, and the center of gravity of human body is often offset screw rod support zone, particularly with people's talk process in, this skew is very common, and the time has been grown, and this just causes base deflection, not only reduce the comfort being seated, and also unbecoming in office; The 2nd, because realization is rotated in rotation in barrel by screw rod, the lifting that has simultaneously produced pitch in the process of rotating, has affected working depth; The 3rd, structure is insecure, easily damages, and is not easy to repair after damage; The 4th, can not dismounting, carrying is inconvenient.

Known by retrieving, have not yet to see and not only can rotate lifting, and can also horizontally rotate, no matter how seat person center of gravity is offset, base can deflection yet, the report that stabilized structure is generous, be convenient to the seat of dismounting transhipment.

Summary of the invention

The purpose of this utility model is to provide one not only can rotate lifting, and can also horizontally rotate, no matter how seat person center of gravity is offset, base can deflection yet, flat turn and the anti-deflection office seating of lifting integral type that stabilized structure is generous, be convenient to dismounting transhipment.

In order to reach above object, the technical scheme that the utility model adopts is: the anti-deflection office seating of this flat turn and lifting integral type, comprise seat base, chair back, handrail and base plate, the bottom of chair back is fixedly connected with the rear end of seat base is vertical, handrail is established left and right two, the rear stiff end of left and right handrail is all by 1/4 height and position that is bolted to the left and right sidewall of chair back, and the front stiff end of left and right handrail is all bolted to 1/4 position of the left and right sidewall of front end of seat base by another, seat base is square, it is characterized in that: the diapire of described seat base is provided with one deck powder metallurgy side plate being fixed as one, be fixed with powder metallurgy annulus at the diapire middle part of powder metallurgy side's plate, described base plate is powder metallurgy plectane, be fixed with powder metallurgy internal thread cylinder at the upper face of base plate, in powder metallurgy internal thread cylinder, screw in the powder metallurgy external screw thread cylinder matching, the overall diameter of powder metallurgy external screw thread cylinder is 1/2 of powder metallurgy side's plate width, the interior diameter of powder metallurgy external screw thread cylinder is consistent with the overall diameter of powder metallurgy annulus, and powder metallurgy internal thread cylinder, the axis coinciding of powder metallurgy external screw thread cylinder and powder metallurgy annulus, the center of powder metallurgy side's plate and base plate is all aimed in its axle center, powder metallurgy annulus snaps in powder metallurgy external screw thread cylinder suitable for reading, upper edge at powder metallurgy external screw thread cylinder is provided with ball bearing, and the diapire of powder metallurgy side's plate touches ball bearing, described powder metallurgy annulus rear wall is provided with clutch cushion hole, stretch out in clutch cushion hole at the tip of clutch pin, seat end and the end part of movable rod that turns of "T"-shaped clutch handle of clutch pin are rotationally connected, and the fulcrum shaft of "T"-shaped clutch handle is fixed on a sidewall rear portion of seat base.

The utility model is also implemented by following measure: 4 bullets of embedding of symmetry in the upper end inwall of described powder metallurgy external screw thread cylinder; The position that the outer wall of described powder metallurgy annulus is corresponding with 4 pellets is provided with circular orbit, and the bulb of pellet is stuck in the circular orbit of powder metallurgy annulus.

The diapire periphery symmetry of described base plate be provided with 4 holes, in hole, all snap in spin, the degree of depth of hole is ball diameters 2/3.

The front end outside of described clutch pin is provided with fairlead, and the rear port of fairlead is along being fixed as one with the edge, clutch cushion aperture of powder metallurgy annulus.

The lever that turns of described "T"-shaped clutch handle is located in powder metallurgy annulus, is fixedly connected with the postmedian of "T"-shaped clutch handle by cross bar.

The beneficial effects of the utility model are: the anti-deflection office seating of this flat turn and lifting integral type, and because two sleeves that are threaded connection rotate, thus can rotate, again can lifting, and strengthened loaded area; Due to by the rotation in sleeve by annulus, realize the flat turn of seat; Owing to being provided with lifting rotation system and the peaceful switching mechanism of transfering from one department to another system, so, can not only lifting rotate, and can horizontally rotate; Because rotary part contact area is large, so slow-roll stabilization, can not deflection; Because metal parts has adopted powder metallurgy making, so alleviated weight, reduce cost of manufacture; Because two sleeves and annulus are to assemble, so can be convenient to dismounting, carrying. Can be widely used in office chair.
