Description

The Three-wheel car

The utility model relates to a kind of foldable carriage for child.

In the prior art, the structure that a kind of four-wheel perambulator is arranged is that the rear portion of the front portion of pushing hands bar and foreleg is rotatably connected and is provided with lockout mechanism, the leading section of foreleg is connected with front-wheel, the upper end of back leg and described pushing hands bar are rotatably connected, the bottom of back leg is connected with trailing wheel, is connected with the seat cushion bar between described foreleg and the back leg, because seat cushion bar top is provided with children's seat cushion, therefore the baby can seat, crouch on seat cushion, the adult promotes the pushing hands bar and can promote perambulator and advance.But take exercise when running morning, and it is then very painstaking to promote this perambulator.

When the purpose of this utility model is to provide a kind of running to promote easily, Three-wheel car easily.

The technical solution of the utility model is: a kind of Three-wheel car, the front portion of two pushing hands bars is rotatably connected with the rear portion of two forelegs respectively, and be provided with lockout mechanism between described pushing hands bar and the described foreleg, the front portion of described two forelegs is crooked symmetrically to the vertical central plane of symmetry of two pushing hands bars, and the leading section of described two forelegs is connected on the wheel shaft of front-wheel, described front-wheel is arranged on the vertical central plane of symmetry of described two pushing hands bars, the leading section of lower link is rotatably connected on the described foreleg, the upper end of rear linking rod is rotationally connected with on the described pushing hands bar, the bottom of described rear linking rod is rotationally connected with the rear portion of described lower link, two trailing wheels are symmetrical arranged in the left and right sides of vertical central plane of symmetry of described pushing hands bar, and the wheel shaft of described trailing wheel is connected in the rearward end of described lower link.

The utility model compared with prior art has following advantage:

Unclamp described lockout mechanism, folding the utility model, then front-wheel and trailing wheel are drawn close mutually, can oneself stand on the ground, and folding back is placed simple.

The utility model will be further described below in conjunction with drawings and Examples:
