Abstract

The invention relates to a cart, which comprises a cart frame at least having folding state and unfolding state, a front wheel assembly arranged on the lower front part of the cart frame, and a rear wheel assembly arranged on the lower rear part of the cart frame. The cart frame comprises a push rod, a front wheel bracket of which the upper end part is in rotating connection with the lower end part of the push rod, a rear wheel bracket of which the upper end part is in rotating connection with the push rod, and a base bar. The front end of the base bar is in rotating connection with the front wheel bracket; and the rear end of the base bar is in rotating connection with the rear wheel bracket g. The cart also comprises a bottom supporting plate, and a connecting rod of which the upper part is fixed on the front wheel bracket; and the lower end part of the connecting rod is in rotating connection with the bottom supporting plate. When the cart frame is in unfolding state, the front end part of the bottom supporting plate is pressed against the front wheel bracket, the rear end part of the bottom supporting plate is pressed against the base bar, and the cart frame is provided with a locking device. The cart frame can be folded in a rotating way, the folding operation is simple and convenient, the size of the cart is reduced obviously after being folded, and the device also has the advantages of carrying easily, and reducing the cost of package, storage and transportation.
