Abstract

The invention relates to a folding tricycle. The baby carriage comprises a front frame, front wheels, a main frame, a rear frame, rear wheels and a backrest, the front frame and the backrest are rotatably connected with the main frame; the main frame is provided with a sliding part capable of sliding in the extending direction of the main frame. The rear frame is rotationally connected with the sliding part; wherein the two ends of the first connecting rod are rotationally connected with the rear end of the main frame and the rear frame respectively, the two ends of the second connecting rod are rotationally connected with the backrest and the sliding part respectively, and when the tricycle is folded, the backrest rotates downwards to be close to the main frame and pushes the sliding partto slide forwards to drive the rear frame to rotate and fold towards the main frame. According to the folding tricycle, sliding folding is achieved by rotating the backrest, the distances in the front-back direction and the two side directions can be synchronously reduced, the purpose of reducing the size of the whole tricycle is achieved, and when the tricycle is not used, the tricycle is more convenient to carry and store.

Description

technical field [0001] The invention relates to the field of children's products, in particular to a folding tricycle. Background technique [0002] A children's tricycle in the prior art mainly includes a front frame, a front wheel connected to the bottom of the front frame, a handlebar connected to the front frame and capable of controlling the steering of the front wheel, and a front part connected to the front frame along the front and rear.
