Abstract

The present invention relates to a trolley which comprises fore legs 2, fore wheels 1 arranged on the fore legs 2, rear legs 11, rear wheels 12 arranged on the rear legs 11 and a push rod 17, wherein the push rod 7 is hinged with the fore legs 2, and the upper ends of the rear legs 11 are hinged with the push rod 7. The front part of a seat cushion rod 15 is hinged with the fore legs 2. The present invention is characterized in that the seat cushion rod 15 is coaxially hinged with the lower end of a fore connecting rod 9 and the front end of a rear connecting rod 4, the rear end of the rear connecting rod 4 is hinged with the rear legs 11, and the upper end of the fore connecting rod 9 is hinged with the push rod 7. After the trolley is unlocked and folded, the fore wheels and the rear wheels can jointly support the trolley, so that the entire trolley is independent, and the conversion of the folding state and the open state of the trolley is convenient.

Description

Go-cart

Technical field

The present invention relates to a kind of doll carriage.

Background technology

In the prior art, go-cart comprises foreleg, be arranged at front-wheel, back leg on the foreleg, be located at trailing wheel, pushing hands bar on the back leg, be hinged between the leading section of described pushing hands bar and the rearward end of foreleg and be provided with lockout mechanism between the two, be hinged by second hinged support between the upper end of described back leg and the pushing hands bar; The front portion of seat cushion bar and described foreleg are hinged, and the rear portion of seat cushion bar and described back leg are hinged.After the lockout mechanism release of the hinged place between pushing hands bar and the foreleg, can rotate around hinge-point between pushing hands bar and the foreleg, whole vehicle frame can fold, but folding back front-wheel and trailing wheel can not support oneself go-cart as the strong point, cause placing the go-cart inconvenience.

Summary of the invention

The object of the present invention is to provide the go-cart that to support oneself after a kind of the folding.

Technical scheme of the present invention is: a kind of go-cart, comprise foreleg, be arranged at front-wheel, back leg on the foreleg, be located at trailing wheel, pushing hands bar on the back leg, be hinged between the leading section of described pushing hands bar and the rearward end of foreleg and be provided with lockout mechanism between the two, be hinged by second hinged support between the upper end of described back leg and the pushing hands bar; The front portion of seat cushion bar and described foreleg are hinged, the seat cushion bar is also by the coaxial bottom of front rod and the leading section of rear linking rod of being hinged with of the 4th hinged support, the rearward end of described rear linking rod and back leg] be hinged by the 3rd hinged support, the upper end of described front rod is hinged by first hinged support and pushing hands bar, between described first hinged support and second hinged support separately.

The present invention compared with prior art has following advantage:

When after the go-cart release during folding finishing, front-wheel and trailing wheel form go-cart jointly and support, and whole go-cart can be supported oneself, and is convenient to the conversion that folds, opens two states of go-cart.
