Description

The one Foldable baby three-wheeled cart of can standing

technical field:

The utility model relates to children trolley technical field, refers in particular to the one Foldable baby three-wheeled cart of can standing.

background technology:

Existing children trolley style is varied, considers the factor such as take up room, and most children trolleys are all designed to folding.But existing this class Foldable stroller conventionally only has two-wheeled to land after folding, cannot stand separately, need to lean on wall or buttress, therefore use and bring inconvenience to people.

utility model content:

The purpose of this utility model is to overcome the weak point of existing product, and the kind Foldable baby three-wheeled cart of can standing is provided.

The utility model is realized the technical scheme that its object adopts: the one Foldable baby three-wheeled cart of can standing, it comprises front foot pipe, rear foot tube, handle pipe and mounting pipe, two upper ends of described front foot pipe and two bottoms of described handle pipe are respectively by the first attaching parts pivot joint, one headgear of this first attaching parts is connected to the end of front foot pipe and is fixedly connected with by screw, and the other end of the first attaching parts and the bottom of handle pipe are by the first drive-connecting shaft pivot joint; Two upper ends of described rear foot tube and the interlude of handle pipe are respectively by the second attaching parts pivot joint, and this second attaching parts is " U " shape, and the second attaching parts is fixedly connected with handle pipe stage casing, pass through the rotatable loose joint of the second drive-connecting shaft with rear foot tube upper end; The rear end of described mounting pipe and the stage casing of rear foot tube are by the 3rd drive-connecting shaft loose joint, and the front end of mounting pipe and the stage casing of described front foot pipe are by the 4th drive-connecting shaft loose joint.

In described handle pipe, be also provided with the limiting stopper contacting with the first attaching parts.

Between two described the first attaching partss, be connected with handrail for children.

In the top of described handle pipe, cover has antiskid glue sleeve.

In described handle pipe, be also provided with a clamping part, be provided with a snap pin in described rear foot tube accordingly.

The utility model makes full use of four-bar linkage principle, and the car load volume after folding of returning the vehicle to the garage and knock off is little and can stand, thereby further reduces the space taking, and offers convenience to user.

brief description of the drawings:

Fig. 1 is the block diagram of the utility model deployed condition;

Fig. 2, Fig. 3 are the schematic diagrams of the utility model folded state.

detailed description of the invention:

Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.

First, as Fig. 1, Fig. 2, shown in Fig. 3, the one described in the utility model Foldable baby three-wheeled cart of can standing, it comprises front foot pipe 1, rear foot tube 2, handle pipe 3 and mounting pipe 4, two upper ends of described front foot pipe 1 and two bottoms of described handle pipe 3 are respectively by the first attaching parts 5 pivot joints, one headgear of this first attaching parts 5 is connected to the end of front foot pipe 1 and is fixedly connected with by screw, the bottom of the other end of the first attaching parts 5 and handle pipe 3 is by the first drive-connecting shaft 51 pivot joints, be that handle pipe 3 can be rotated and front foot pipe 1 is rotated with respect to the first attaching parts 5, two upper ends of described rear foot tube 2 and the interlude of handle pipe 3 are respectively by the second attaching parts pivot joint 6, this second attaching parts 6 is " U " shape, the second attaching parts 6 is fixedly connected with handle pipe 3 stage casings, " U " shape to be the second attaching parts 6 frames in handle pipe 3 stage casings peripheral and be fixedly connected with by screw, and pass through the rotatable loose joint of the second drive-connecting shaft 61 with rear foot tube 2 upper ends, handle pipe 3 can be rotated with respect to rear foot tube 2, the stage casing of the rear end of described mounting pipe 4 and rear foot tube 2 is by the 3rd drive-connecting shaft 41 loose joints, and the stage casing of the front end of mounting pipe 4 and described front foot pipe 1 is by the 4th drive-connecting shaft 42 loose joints.

In described handle pipe 3, be also provided with the limiting stopper 31 contacting with the first attaching parts 5.In the time of deployed condition, realize front foot pipe 1 rotary stopper relative to handle pipe 3 by the conflict between the first attaching parts 5 and limiting stopper 31 between front foot pipe 1 and handle pipe 3, or, in the situation that there is no limiting stopper, when being 180 between front foot pipe 1 and handle pipe 3 while spending, also can realize rotary stopper.

Between two described the first attaching partss 5, be connected with handrail for children 52.

In the top of described handle pipe 3, cover has antiskid glue sleeve 32, and in the time of folded state, antiskid glue sleeve 32 contacts with ground, plays better skidproof effect.

In described handle pipe 3, be also provided with a clamping part 33, be provided with a snap pin 21 in described rear foot tube 2 accordingly.While folding, this clamping part 33 just and snap pin 21 realize snapping, thereby make whole go-cart more easily keep folded state.

Return the vehicle to the garage and knock off while folding, can pin on the other hand handle pipe 3 to pressing down, handle pipe 3 is rotated around the second attaching parts 6 and rear foot tube 2 junctions, the first attaching parts 5 of handle pipe 3 bottoms departs from limiting stopper 31, and handle pipe 3 bottoms by the first attaching parts 5 and front foot pipe 1 end to pop-up, correspondingly upward movement of mounting pipe 4 simultaneously, front foot pipe 1 is drawn close mutually with mounting pipe 4 belows, starts to fold; While contact with ground, reach complete folded state below the upper end of handle pipe 3 rotation extremely, keep folding by the clamping part 33 in handle pipe 3 and the snap pin 21 on rear foot tube 2; Now, between the top of handle pipe 3 and two trailing wheels, form three points and support and ground, stand thereby realize after car load folds.
