Abstract
The utility model relates to a chair foot, in particular to a chair foot structure for an office swivel chair, comprising a centre axle hole and a plurality of support bars uniformly distributed aside the centre axle hole. The front end of the support bar is provided with a trolley mounting hole. The support bar is formed by welding a support bar base with a strengthening rib. The strengthening rib is integral, one end of which is connected with the centre axle hole and the other end is connected with the trolley mounting hole along the length direction of the support bar. The strengthening rib comprises a strengthening rib main body, a trolley mounting hole and a strengthening rib foot stand. The centre axle hole is in star connection with the support bars. The structure has the advantages that the welding process is decreased, the cost and materials are saved, the structure is reasonable, the load-carrying capability is fine and the structure can meet the actual loading demand.
Description
Affiliated technical field
The utility model relates to a kind of chair leg structure of chair pin, especially office revolving chair.
Background technology
The chair pin plays important effect in swivel chair.Existing swivel chair chair pin generally adopts the injection moulding mode to machine, and its structure roughly comprises the leg that a centre mount and several and centre mount are fixed as one, and scroll wheel is installed in leg front end bottom.Leg for fear of inner hollow is being subjected to doing time spent appearance damage than big external force, and people add reinforcement and a plurality of auxiliary stiffener that becomes a fixed inclination with reinforcement in hollow feet, increase chair pin intensity with this.
Chinese utility model patent CN 200998048Y in Granted publication on January 2nd, 2008, disclose a kind of office chair chair leg structure, one to three waling and some auxiliary stiffeners that intersects with reinforcement and hollow feet inwall have been arranged in this center leg.
Chinese utility model patent CN 201085309Y in Granted publication on July 16th, 2008, disclose the chair pin of similar structures, had one in the hollow out chamber of this leg, sleeve pipe at least along the reinforcement of leg length direction and be provided with a plurality of and the oblique reinforcement reinforcement bevel.
Adopt this structure to overcome the intensity defective that plastic material itself brings to a certain extent.But this structure need be installed oblique reinforcement or auxiliary stiffener, must repeatedly cut and weld, and has increased manufacturing process, and cost also increases greatly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can reduce manufacturing process, and economical with materials reduces cost, and satisfies the actual strength needs, and rational in infrastructure, stressed uniform swivel chair chair pin.
The technical scheme of the utility model swivel chair chair pin, comprise central shaft hole and be evenly distributed on some other legs of central shaft hole, the front end of leg is provided with the roller installing hole, described leg is welded by leg base and reinforcement two parts, described reinforcement is an integral body, comprise reinforcement trunk, roller installing hole and reinforcement foot rest, an end of reinforcement is connected with central shaft hole, and the other end is connected with roller installing hole along the leg length direction.Described central shaft hole is star-like shape with some legs and is connected.
The beneficial effects of the utility model are, have reduced welding sequence, save cost and material, and are rational in infrastructure, stressed evenly, can satisfy the actual loading needs.
