Abstract
An office chair leg comprises a mounting hole allowing a column to be mounted, and support legs uniformly distributed and welded on the outer circumference of the mounting hole, and is characterized in that the support legs are hollow bodies formed by stamping and bending plates; first strengthening ribs extending from the end of the mounting hole to the top ends of the support legs are arranged on the lower surfaces of the support legs in a bent manner; two sides of the plates are bent inwards into the support legs so that second strengthening ribs are formed; and the joints of the second strengthening ribs are welded to ensure that the support legs are closed. The cross section of each of the support legs takes the shape of the Chinese character 'tu', and the first strengthening ribs are arranged at the raised parts. The office chair leg has the benefits of simple structure, strong bearing capacity of the chair leg, long service life, low construction cost and the like.
Description
Technical field
The utility model relates to the office accommodation technical field, especially relates to a kind of chair pin of the chair of handling official business.
Background technology
Office chair is one of requisite apparatus in all kinds of office spaces, and office chair itself also has polytype.Wherein the rotating office chair use of seat is wider, and the chair pin of this office chair generally adopts the mode of injection mo(u)lding to make, and its structure roughly comprises a centre mount and the some legs that are fixed with one with centre mount; Look up from the lower end of leg; Its inside is hollow form, though can reach the purpose of saving material and weight reduction like this, has weakened the intensity of leg to a certain extent; Make leg do the time spent and fracture, bad phenomenon such as distortion occur easily receiving bigger external force.Also have metal material monoblock casts such as using aluminium alloy to form, but the metal material cost is expensive, production cost is high, and Heavy Weight has limited its marketing ability equally.
The utility model content
It is a kind of simple in structure that the purpose of the utility model is to provide, and chair pin bearing capacity is strong, long service life, the Legs of office chair that cost is low.
The utility model is realized through following technical scheme: a kind of Legs of office chair; Comprise the installing hole that column is installed; And evenly distribution is welded on the leg on the installing hole excircle, it is characterized in that: described leg is the hollow body that the plate stamping bending forms, and is bent with on the lower surface of leg by first reinforcement that nose end extends to the leg top is installed; The sheet material dual-side bends inwards into forming second reinforcement in the leg, and it is airtight to make that in the welding of the second reinforcement joint leg forms.
Described leg cross section is down " protruding " word shape, and the part of protrusion is first reinforcement.
Described second reinforcement is positioned at the top of first reinforcement.
Described first reinforcement by install nose end to the leg top from height to short extension.
Described leg top is provided with the castor installing hole.
The beneficial effect of the utility model is: have simple in structurely, chair pin bearing capacity is strong, long service life, advantage such as cost is low.
Description of drawings
Fig. 1,2, the 3rd, the utility model surface structure sketch map.
Fig. 4 is an A-A schematic cross-section among Fig. 3 in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to explain.As shown in the figure: a kind of Legs of office chair; Comprise the installing hole 1 that column is installed; And evenly distribution is welded on the leg 2 on the installing hole excircle, it is characterized in that: described leg 2 is the hollow body that the plate stamping bending forms, and is bent with first reinforcement 4 that is extended to the leg top by installing hole 1 end on the lower surface of leg 2; The sheet material dual-side bends inwards into forming second reinforcement 5 in the leg, and it is airtight to make that in the welding of second reinforcement, 5 joints leg forms.
Described leg 2 cross sections are down " protruding " word shape, and the part of protrusion is first reinforcement 4.
Described second reinforcement 5 is positioned at the top of first reinforcement 4.
Described first reinforcement 4 by installing hole 1 end to leg 2 tops from height to short extension.
Described leg 2 tops are provided with castor installing hole 3.
When producing, behind drawing leg 2, use the electric welding mode in the welding of second reinforcement, 5 joints, form solder joint 6, in use, first reinforcement 4 that is stamped to form and second reinforcement 5 all can play the effect of strengthening the leg bearing capacity with solder joint 6.Use plastics and metal material cast-in-block mode to compare with conventional art; The utility model can adopt the iron plate below the 1mm to make; The reinforcement of design on leg 2, and electricity consumption sealing limit makes leg form the bearing capacity that airtight mode has effectively guaranteed leg.Have simple in structure, advantage such as production technology is simple, and bearing capacity is strong.
