Abstract

The invention discloses a stable roller for mall shopping carts. The stable roller comprises a pedestal, a brake roller body and a roller bodies; two lugs are arranged on one side of the pedestal in a protruding manner, the brake roller body is arranged between the lugs, the roller bodies are arranged between the lugs and the brake roller body, and a pin roll penetrates the lugs, the roller bodies and the brake roller body; a brake block is arranged at the bottom of the brake roller body, and a high-friction-coefficient layer is arranged at the bottom of the brake block; the stable roller further comprises elastic buffer pieces and limit blocks, two accommodating grooves used for accommodating the limit blocks and the elastic buffer pieces are respectively arranged on outer sides of the roller bodies, and the elastic buffer piece are arranged between the corresponding roller bodies and the corresponding limit blocks. By the arrangement of the elastic buffer pieces and the limit blocks, the roller bodies are pressed to the middle of the pin roll, and swinging of the roller bodies from side to side during rolling is avoided.

Description

Technical field [0001] The invention relates to a roller, in particular to a stable roller for shopping carts in shopping malls.
