The invention discloses a mute roller used for a mall shopping trolley. The mute roller comprises a base, a braking wheel body and rolling wheel bodies. Two protruding pieces are arranged on one side of the base in a protruding mode; the braking wheel body is arranged between the two protruding pieces; the rolling wheel bodies are arranged between the protruding pieces and the braking wheel body; a pin shaft penetrates through the protruding pieces, the rolling wheel bodies and the braking wheel body; a braking block is arranged at the bottom of the braking wheel body; a high friction coefficient layer is arranged at the bottom of the braking block; a sleeving cylinder is arranged in the middle of the braking wheel body; a mute cotton layer is arranged on the inner wall of the sleeving cylinder; and the pin shaft penetrates through the sleeving cylinder. According to the mute roller used for the mall shopping trolley, by utilizing the mute cotton layer arranged in the sleeving cylinder of the braking wheel body, noise is not generated between the pin shaft and the braking wheel body due to friction, and meanwhile friction noise between the pin shaft and the rolling wheel bodies is reduced through gaskets.
Description
technical field [0001] The invention relates to a roller, in particular to a silent roller used for a shopping cart in a shopping mall. Background technique [0002] Shopping carts are used in large supermarkets or shopping malls. The shopping carts are equipped with casters, so that everything looks comfortable and comfortable. Without casters, customers will no longer shop easily. Heavy loads, high sills, and the wide variety between refrigerated areas and store counters place high demands on shopping cart castors. [0003] Customers use the inclined escalator to move between floors in the shopping mall. After the rollers of the shopping cart are embedded in the brake grooves on the surface of the inclined escalator, it is difficult to move, thereby preventing the shopping cart from sliding on the inclined escalator. The rollers of the existing shopping carts have complex structures, and the connections between the parts are not tight enough, and shaking occurs during the...
