Description
Technical Field
[0001] The utility model relates to the technical field of wheelbarrows, in particular to an outdoor folding wheelbarrow. Background Art
[0002] With the improvement of living standards, more and more people like to drive to outdoor activities, and they will carry a lot of picnic food and outdoor equipment when driving. However, the car can generally only be driven to the parking place, and the remaining distance mostly needs to be completed on foot. It is very inconvenient for people to carry so many things for outdoor hiking. Now, trolleys that can be folded and placed in the trunk are also sold on the market. When in use, the trolley can be stretched and opened to form a storage basket to place picnic food and outdoor equipment, which is convenient for people to carry.
[0003] After the existing trolleys are produced, most of them are directly folded and packaged for shipment. This method is prone to the following problems: first, the packaging volume is too large and the transportation cost is too high; second, when some parts are damaged, consumers cannot repair or replace the parts by themselves.
