Description

Children's barrow

Technical Field

The application relates to the field of perambulator spare part, especially relate to a children's shallow.

Background

The children's barrow is a tool car designed for providing convenience for outdoor activities of children, and parents put infants who do not learn to walk in the children's barrow so as to bring convenience for outdoor activities of children; the child who learns to walk can also rest on the stroller.

At present, the child is vigorous, the activity amount is large during activity, the activity intensity of the child in the child stroller is large, and the child can drive the child stroller to rock together during the activity process in the child stroller. When the child stroller is suspended on dangerous terrain such as a slope, and a child moves in the child stroller, the child stroller can slide down the slope due to the fact that the child stroller shakes. In order to reduce the similar phenomenon, a brake is arranged at the rear wheel of the baby stroller, and the brake blocks the sliding tendency of the baby stroller.

In view of the above-mentioned related technologies, the inventor believes that, because the movement range of the child in the stroller is large, although the brake can block the tendency of the stroller to slide on a slope, the stroller still has a certain range of shaking, and the stroller slowly slides down.
