Invention content
The purpose of this utility model is to provide a kind of foldable and the minimum folding baby cart of volume after folding.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of folding baby cart, including before two
Wheel, two trailing wheels, front-wheel support, rear wheel support, pulling handle rod, cushion rods, the pulling handle rod are " u "-shaped, two front-wheels point
It is not rotatablely connected by front-wheel support and the pulling handle rod both ends, two trailing wheels are fixed on by rear wheel support described respectively
On front-wheel support, supporting support, the supporting support and the front-wheel are connected between the rear wheel support and the pulling handle rod
Cushion rod is connected between holder, it is characterised in that：The cushion rod end is connected with center ten with the front-wheel support end
Word supports holder, and bottom cross holder is provided between the rear wheel support.
In above-mentioned technical proposal, pulling handle rod interlude is three-stage foldable structure, is taken the shape of the letter U after folding.
Preferred technical solution, the supporting support lower end are rotatably connected on the rear wheel support.
Preferred technical solution, the central cross support center left socle, the right branch in center that holder includes arranged in a crossed manner
Frame, the center left socle and center right support are rotatablely connected by the fixing piece at center.
Preferred technical solution, the bottom cross holder include bottom left socle arranged in a crossed manner, bottom right support, the bottom
Left socle, bottom right support are rotatablely connected by the fixing piece at center.
The operation principle of the utility model：
The utility model uses quadrangle principle, by the front-wheel support of both sides, rear wheel support, pulling handle rod and supporting support group
At quadrangle so that original quadrangle is converted to triangle by locking pulling handle rod and front-wheel support, fixed both sides vehicle body,
Rear wheel support is no motion of in folding, and both sides front-wheel support supports holder by central cross and connects, when vehicle folds,
The quadrangle movement of both sides can drive central cross to support support motion.When folding baby cart folds, first it is folded left and right,
Left and right front-wheel support is drawn close to centre, and central cross supports stent collapses, bottom cross stent collapses, and pulling handle rod is folded into three sections；
Be folded up and down again, rotate backward after supporting support, front-wheel and drawn close to rear wheel support, after pulling handle rod rotation with front-wheel support
It folds.When folding baby cart is unfolded, front-wheel support, rear wheel support and supporting support are locked as triangle, center
Cross holder, the expansion of bottom cross holder, central cross support holder, bottom cross holder support unitized frame, in addition
It is provided with locking mechanism on pulling handle rod, horizontal rear support can be provided by the fixed pulling handle rod of locking for vehicle body.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
1. the utility model has the advantages of simple structure, volume after folding is minimum, easy to carry, easy to operate, solid reliable；
2. the central cross support holder, bottom cross holder of the utility model enable cart to be folded into minimum body
Product, and it is easy to operate.
