Abstract
The present invention relates to a dolly which comprises two side supporting frames and cross connecting rods for linking the two side supporting frames, wherein each side supporting frame comprises a pushing rod, a front connecting rod, lower connecting rods, rear connecting rods, a rear wheel and a front wheel. The cross connecting rod is arranged between the lower connecting rods of the two side supporting frames, the outer end of the third cross connecting rod is in pivotal connection with the lower connecting rod at one side, the outer end of the fourth connecting rod is in pivotal connection with the lower connecting rod at the other side. The inner ends of the third cross connecting rod and the fourth cross connecting rod are movably connected with each other, the rear connecting rod at each side is respectively in pivotal connection with one end of the pushing rod, and the other end of each pushing rod is respectively in pivotal connection with the fourth cross connecting rod and the third cross connecting rod. The longitudinal dimension and the horizontal dimension are both reduced after the dolly is folded, and the dolly is conveniently packed, transported and carried.
Description
Technical field
The present invention relates to a kind of doll carriage.
