Abstract
The invention relates to a folding children cart which comprises a cart frame, a first front wheel assembly, a first rear wheel assembly and a locking device for locking the cart frame in an unfolding position. The cart frame comprises a first front bracket, a first front driving rod which is arranged slidably relative to the first front bracket, a first rear wheel frame, a first push rod frame which is arranged slidably relative to the first rear wheel frame, a first seat frame and a first swinging rod, wherein the rear part of the first seat frame is rotatably connected with the lower part of the first push rod frame, and the front part of first swinging rod is rotatably connected with the first seat frame. When the locking device is unlocked, the first driving rod slides downwards relative to the first front bracket; the first push rod frame slides downwards relative to the first push rod frame; and the first push rod frame drives the rear end part of the first seat frame to slide downwards so that the first front bracket approaches the first rear wheel frame relatively, thus, the children cart is folded. After folding, the first front wheel assembly and the first rear wheel assembly land to support the cart frame to realize self standing; and at this moment, the first push rod frame still erects, which is convenient for users to take. The children cart is simple in structure.
