Abstract
The utility model relates to a stair of an escalator. The stair of the escalator comprises a footboard, a kickplate assembly, two supporting plates and a stair shaft seat. Anti-skidding teeth are arranged on a stepping face of the footboard. The right side and the left side of the pedal are connected with the supporting plates. Tooth distances on the stepping face of the footboard are equal to tooth distances on the supporting plates. Teeth on faces of footboards of adjacent stairs are meshed with grooves in the supporting plates. One side of a stair main wheel shaft seat is fixed on a side of a triangular support and the other side of the stair main wheel shaft seat is fixed on a beam which connects a right triangular support with a left triangular support. The kickplate assembly comprises a front kickplate assembly and a rear kickplate assembly which are fixed on the front side and the rear side of each supporting plate respectively. A reinforced cavity is formed in each triangular support. Reinforced ribs with folded edges are on the circumference of each reinforced cavity. The stair of the escalator has the advantages that the anti-skidding teeth are arranged on the stepping face of the footboard and arc gaps are arranged among the anti-skidding teeth so that the escalator is good in effect of preventing skidding, safety of the escalator is improved; the reinforced cavities are formed in the triangular supports and the reinforced ribs with the folded edges are arranged on the circumference of each reinforced cavity so that the escalator is firmer and has longer service life.
