Spliced mini-type racing track for track cycling

The utility model discloses a spliced mini-type racing track for track cycling. The spliced mini-type racing track comprises a base seat and a racing track body, wherein the base seat is composed by connecting trusses in sequence; fixed floors are mounted on the supporting surfaces of the two adjacent single slope trusses; the floors on the surfaces of the trusses are cling to each other to form a whole enclosed annular racing track; two straight track parts and two bent track parts are arranged on the annular base seat and racing track; the supporting surfaces of the straight track parts adopt straight inclined plane structures, and the outward incline angles are 13 DEG C; the supporting surfaces of the bent track parts adopt fan-annular structures; the incline angles of the two end edges of the bent track parts are 13 DEG C; the incline angle of a center line is 38 DEG C; the incline angles from the two end edges to the center line are increased uniformly and gradually; the floors on the straight track parts and that on the bent track parts are transited gradually and smoothly; the two ends of each straight track part are communicated with the lower ends of the two bent track parts respectively to form the annular base seat. The spliced mini-type racing track has the advantages of simple assembly and disassembly, small size, lower material consumption and the like.
