Description

Technical Field

[0001] The utility model relates to the technical field of baby walkers, in particular to an anti-dumping baby walker. Background Art

[0002] A walker is a tool for babies to learn to walk. In the prior art, walkers are generally two-wheeled or two-wheeled with auxiliary wheels. When a two-wheeled walker is used, it is easy for a small child to tip over when sliding due to insufficient leg strength. When a two-wheeled walker with auxiliary wheels is used, the two small auxiliary wheels are connected to both sides of the rear wheel, which will cause the rear wheel to occupy a larger lateral area, and it is easy to bump into hard objects and cause the walker to tip over, which poses certain safety hazards. In addition, since this type of walker occupies a large area, it is also difficult to place. Therefore, we propose an anti-tipping walker. Utility Model Content
