Description

Handcart Technical Field The invention relates to the technical field of supermarket trolleys, in particular to a trolley. Background The handcart is used as a common carrying tool in the scenes of super business, storage, logistics and the like, and the use convenience, the storage and transportation cost and the maintenance efficiency of the handcart directly influence the application experience. At present, most of supermarket trolleys widely applied to the market are of an integrated welding structure, and for example, the domestic appearance design with the application number of CN201130084134.3 discloses the supermarket trolleys. The handcart is applicable to baby seat structure from taking of most supermarket handcart, namely turns over board type seat structure, but its turns over board structure and basket body curb plate hinge for the seat board, the motion mode of this end seat board can only be for doing circular rotary motion around the connecting axle, the seat board other end is connected through the connecting rod on with the backplate and is realized opening and shutting and pack up, because the seat board other end is fixed for the block with the connecting rod on the backplate, so the seat board can always expose in the environment when packing up the state, receive the injury of environment or the customer is in the storing state under the state of not needing to use the table chair, thereby the article of putting into can strike the seat board loss seat board for seat board life-span shortens, unable normal work. Meanwhile, the frame, basket body, wheel frame and other core components of the handcart are fixedly connected through a welding process, and the handcart has certain structural strength, but in the use process, the wheel frame is deformed, welding spots of the basket body fall off, pushing hands are broken and the like, but due to the fact that the components are welded and fixed, the single damaged component cannot be disassembled and replaced, the whole handcart can only be scrapped or returned to a factory for whole welding maintenance, the maintenance difficulty is high, the cost is high, and meanwhile, the problem of high transportation cost exists. What is needed is a cart that provides a more stable and longer lasting child-carrying capability while allowing for a split assembly.
