Description

Children trolley

Technical field

The utility model relates to a kind of children trolley.

Background technology

Children trolley is as infant's the instrument of the taking necessary articles for use of family outdoor leisure of holding concurrently, accepted by increasing family, such as, the household is necessary with children trolley on child's tourism belt, to such an extent as to and children trolley can not be placed in the boot of automobile greatly in the expanded position lower volume, must be after folding, just can be placed in the boot of automobile.This shows that the most basic requirement is that volume after folding is less for children trolley, and the children trolley of the prior art bigger defective of ubiquity volume after folding still.

The utility model content

The technical problems to be solved in the utility model is a kind of children trolley, and its volume after folding is less.

The technical solution adopted in the utility model is: a kind of children trolley, comprise go-cart vehicle frame, front component, wheel assembly, be arranged at the first seat mechanism on the described go-cart vehicle frame, be used for described go-cart vehicle frame is locked in the lockout mechanism of expanded position with expanded position and folding position

Described go-cart vehicle frame comprises:

First front frame, second front frame;

First after poppet, the front portion of described first after poppet is connected rotatedly with described first front frame;

Second after poppet, the front portion of described second after poppet is connected rotatedly with described second front frame;

First push rod, described first push rod is connected rotatedly with the rearward end of described first front frame;
