Description

Umbrella-type pram

The utility model relates to a kind of perambulator, particularly umbrella handle vehicle.

In the prior art, umbrella handle vehicle is a kind of common perambulator, comprise first foreleg and second foreleg, be arranged at first front-wheel of the below of described first foreleg, be arranged at second front-wheel of described second foreleg below, first back leg and second back leg, be arranged at first trailing wheel of the below of described first back leg, be arranged at second trailing wheel of the below of described second back leg, the first pushing hands bar with the first foreleg pivotal joint, the second pushing hands bar with the second foreleg pivotal joint, be provided with the attaching parts that intersects between described back leg and the pushing hands bar, it is horizontal and vertical folding to make that handle of umbrella can carry out when folding simultaneously, and the volume after it is folding is little.But owing to umbrella handle vehicle for the laterally folded transverse link that lacks, be sitting on the seat back and ride after on the soft step band the baby, first foreleg and second foreleg are subjected to the horizontal power towards the center, make two forelegs towards the bending of the other side's direction, then the axle of two front-wheels is non-horizontal direction, makes that promoting umbrella handle vehicle produces difficulty.

The purpose of this utility model is to provide the umbrella-type pram of the rigidity between a kind of two forelegs that can improve umbrella handle vehicle.

The technical solution of the utility model is: a kind of umbrella-type pram, comprise first foreleg and second foreleg, be arranged at first front-wheel of the below of described first foreleg, be arranged at second front-wheel of described second foreleg below, first back leg and second back leg, be arranged at first trailing wheel of the below of described first back leg, be arranged at second trailing wheel of the below of described second back leg, the first pushing hands bar with the first foreleg pivotal joint, the second pushing hands bar with the second foreleg pivotal joint, be hinged with the outer end of first boxed rod and the outer end of second boxed rod on described first foreleg and second foreleg respectively, described first boxed rod and described second boxed rod are hinged, the inner end of described first boxed rod is hinged with the inner end of second lower link, the outer end of described second lower link and second foreleg are hinged, the inner end of described second boxed rod is hinged with the inner end of first lower link, and the outer end of described first lower link and first foreleg are hinged.

The utility model compared with prior art has following advantage:

After umbrella handle vehicle is opened, first boxed rod and second boxed rod, first lower link and the formed connecting rod mechanism of second lower link can support forming between two forelegs, strengthen rigidity and stability between two forelegs, make two diastrophic defectives of foreleg subtend when having overcome the baby and being sitting on the seat or when riding on soft step band, when folding, above-mentioned connecting rod does not influence the horizontal and vertical folding of car load.

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

Accompanying drawing 1 is a perspective view of the present utility model;

Accompanying drawing 2 is the folded state diagrams of two connecting rods between the foreleg in folding process; Wherein: [1], soft step band; [2], first lower link; [3], first foreleg; [4], first boxed rod; [5], first back leg; [6], the first pushing hands bar; [7], the second pushing hands bar; [8], second back leg; [9], second trailing wheel; [10], first trailing wheel; [11], second boxed rod; [12], second foreleg; [13], second lower link; [14], second front-wheel; [15], first front-wheel;
