Abstract
A foldable carriage for children is composed of left and right supporting frames and several transverse connecting rods for connecting both supporting frames with each other. Each supporting frame consists of manual push rod, the front, lower and back connecting rods, and front and back wheels.
Description
Technical field
The present invention relates to a kind of doll carriage.
Background technology
In the prior art, go-cart, comprise two side stands and be used to connect the tranverse connecting rod of two side stands, described each side stand comprises the front-wheel of the front portion of pushing hands bar, front rod, lower link, rear linking rod, the trailing wheel that is arranged at the rear portion of lower link, the front portion that is arranged at lower link or front rod, go-cart can be folding with instant packed and transportation at above-below direction, but this go-cart can't be laterally folded, therefore do not change in horizontal size before and after car load is folding, carries inconvenience.
Summary of the invention
The object of the invention provide a kind of can be when car load be longitudinal folding, the go-cart that car load also can be laterally folded.
Technical scheme of the present invention is: a kind of go-cart, comprise two side stands and be used to connect the tranverse connecting rod of two side stands, described each side stand comprises the pushing hands bar, front rod, lower link, rear linking rod, be arranged at the trailing wheel at the rear portion of lower link, be arranged at the front-wheel of the front portion of the front portion of lower link or front rod, the rearward end pivotal joint of described pushing hands bar and front rod, described pushing hands bar extends to form the preceding extension of pushing hands bar from the pivotal joint place with front rod to the front lower place, the anterior pivotal joint of the front portion of described lower link and front rod, the bottom of described rear linking rod is connected with the back pivot of lower link, the upper end of described rear linking rod and the preceding extension of pushing hands bar pivotal joint, be provided with tranverse connecting rod between the lower link on described two side stands, this tranverse connecting rod comprises the 3rd tranverse connecting rod at least, the 4th tranverse connecting rod, the lower link pivotal joint of the outer end of the 3rd tranverse connecting rod and a side, the lower link pivotal joint of the outer end of the 4th connecting rod and opposite side, the 3rd tranverse connecting rod, connect versatilely between the inner end of the 4th tranverse connecting rod, on the rear linking rod of described every side respectively pivotal joint one end of pull bar is arranged, the other end of every pull bar respectively with the 4th tranverse connecting rod and the 3rd tranverse connecting rod pivotal joint.
The present invention compared with prior art has following advantage:
When car load folded, rear linking rod drive pull bar moved, and pull bar drives the 3rd tranverse connecting rod again, the 4th tranverse connecting rod is folding, and then car load can fold, and longitudinal size after folding and horizontal chi rain have all reduced, and are convenient to packed and transported and carry.
