Abstract
The invention relates to a trolley for children, comprising a frame. The frame consists of a front wheel rack, a rear wheel rack, a push rod, a sliding element, a support rod of the rear wheel rack and a support rod of the push rod, wherein the lower end part of the rear wheel rack is rotationally connected with the rear end part of the front wheel rack, the front end part of the push rod is rotationally connected with the upper end part of the rear wheel rack, and the sliding element capable of sliding along the rear wheel rack up and down is arranged on the rear wheel rack; one end part of the support rod of the rear wheel rack is rotationally connected with the front part of the front wheel rack, one end part of the support rod of the push rod is rotationally connected with the front part of the push rod, the other end part of the rear wheel rack is rotationally connected with the sliding element, and the other end part of the support rod of the push rod is also rotationally connected with the sliding element. When the frame of the trolley is locked in an unfolding position, the push rod, the rear wheel rack and the support rod of the push rod form a triangle, and the front wheel rack, the rear wheel rack and the support rod of the rear wheel rack form another triangle, therefore, the frame of the trolley has high rigidity in the unfolding position, less rods and simple structure.
Description
Technical field
The present invention relates to a kind of children trolley.
Background technology
Children trolley of the prior art, comprise the go-cart vehicle frame, be arranged on front portion at the bottom of the described go-cart vehicle frame front component, be arranged on the wheel assembly at rear portion at the bottom of the described go-cart vehicle frame.The structure of go-cart vehicle frame is numerous, and the rod member of some go-cart vehicle frame is more, and manufacturing cost is higher relatively.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of children trolley.
Solving the problems of the technologies described above, a kind of technical scheme that the present invention adopts is: a kind of children trolley, comprise go-cart vehicle frame with expanded position and folding position, be arranged on front portion at the bottom of the described go-cart vehicle frame front component, be arranged on rear portion at the bottom of the described go-cart vehicle frame wheel assembly, be arranged on the described go-cart vehicle frame and described go-cart vehicle frame can be locked in the lockout mechanism of expanded position, described go-cart vehicle frame comprises:
Front-wheel support;
Rear wheel support, the bottom of described rear wheel support is connected rotatedly with the rearward end of described front-wheel support;
Push rod, the leading section of described push rod is connected rotatedly with the upper end of described rear wheel support;
