Description

Doll carriage

Technical field

The utility model relates to the go-cart of a kind of vehicle frame Foldable baby.

Background technology

In the prior art, the vehicle frame of doll carriage can fold greatly, dwindles packaging volume with this, but the cushion rod that is used for supporting cushion often occupies sizable space at the rear portion of vehicle frame after folding, make troubles to vehicle frame vanning and transportation.

Summary of the invention

The utility model purpose provides a kind of doll carriage, overcomes the shortcoming of prior art, and volume-diminished behind its vehicle frame folding can be dwindled packaging volume when making vanning.

For achieving the above object, the technical solution adopted in the utility model is: a kind of doll carriage, comprise vehicle frame and be arranged at the front-wheel and the trailing wheel of described vehicle frame below, described vehicle frame comprises the pushing hands bar, upper end and pushing hands bar phase pivot bonded assembly rear wheel support, the bottom phase pivot bonded assembly front-wheel support of upper end and pushing hands bar, bottom supporting rod, cushion rod, the anterior pivotal joint of the bottom of described front-wheel support and bottom supporting rod, the bottom of described rear wheel support is connected with the back pivot of bottom supporting rod, the front portion of described cushion rod is provided with latch hook, described latch hook removably is pivotally connected on the described front-wheel support, this latch hook has two mode of operations: first mode of operation is latch hook and front-wheel support pivotal joint, and second mode of operation is that latch hook is thrown off described front-wheel support; The back pivot of described cushion rod is connected with an end of rear linking rod, the other end of described rear linking rod and rear wheel support pivotal joint.

Because technique scheme utilization, the utility model compared with prior art has following advantage: the cushion rod that is used for supporting cushion on the vehicle frame of this doll carriage in the vehicle frame folding process before this latch hook be in first mode of operation, behind the vehicle frame folding, then make latch hook throw off front-wheel support, latch hook is in second mode of operation, forward plough under vehicle frame in together with rear linking rod cushion rod then, make the rearmost end of vehicle frame and distance foremost reduce, the length that can reduce to case, thereby reduce packaging volume, bring great convenience to transportation.
