Abstract
The utility model discloses a five-wheel swivel chair foot, which includes a basal piece with a bushing hole and five supporting feet which are evenly distributed and fixed on the outer circle of the basal piece and extend outward. The front part of the supporting feet is provided with idler wheel installing holes, and the cross section of the supporting feet are downward concave cavities. In the concave cavities, two long reinforcing ribs and two short reinforcing ribs, a plurality of oblique reinforcing ribs intersecting with each other, and a plurality of transverse reinforcing ribs are arranged. A plurality of radial reinforcing pieces are arranged at the front parts of the seats of the idler wheel installing holes; semicircular reinforcing pieces are arranged at the front part in the concave cavities. The concave cavities, the long reinforcing ribs, the short reinforcing ribs, the oblique reinforcing ribs, the transverse reinforcing ribs, the reinforcing pieces and the semicircular reinforcing pieces are connected with each other to form an integral body. The five-wheel swivel chair foot has rational structure, saves raw materials, and can sustain an upper stress of 1.136 tons under static stress, which is the requirement stipulated in the international (BIFMA) standard.
