Description
Technical field
The present invention relates to a kind of children trolley.
Background technology
Children trolley of the prior art, accepted by increasing family, when going out, the go-cart vehicle frame is opened, children trolley can be for infant sitting, alleviating caregiver's burden, and when needs transport children trolley, hope can be convenient to carrying to reduce volume with children trolley is folding usually.In the prior art, the Most of children go-cart just merely considers how the go-cart vehicle frame folding is realized trying one's best littleization when design, and do not remove to consider the state that presented behind the go-cart vehicle frame folding, as some children trolley folding after just on all fours, push rod promptly extends along fore-and-aft direction, during carrying, be not easy to take; Can realize supporting oneself after also some children trolley folds, but the upper end of push rod is downward, when the user launched children trolley again, the user must bend over the bottom of the push rod of taking so that the inconvenience of taking is opened children trolley in realization.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of can fold support oneself and the upper end of folding rear push-rod can be still straight up children trolley.
For achieving the above object, the technical solution used in the present invention is:
A kind of children trolley comprises go-cart vehicle frame, front component, wheel assembly with open position and folding position, is arranged on the lockout mechanism that is used for described go-cart vehicle frame is locked in open position on the described go-cart vehicle frame,
Described go-cart vehicle frame comprises first side stand and second side stand that lay respectively at both sides, is connected the link span between described first side stand and described second side stand, described link span can be can be laterally folded and make the relative link span of drawing close with second side stand of the side stand of winning, and promptly children trolley can be laterally folded; Also can be the many cross bars that two ends are fixedly connected with the corresponding site of first side stand and second side stand respectively, this structure makes the side stand of winning can not draw close relatively with second side stand, and promptly children trolley can not be laterally folded,
Described first side stand comprises the top of first front-wheel support, top and described first front-wheel support rotate bonded assembly first rear wheel support, first push rod,
