Description

The baby stroller frame that can vertically place after a kind of the folding

[technical field]

The utility model relates to a kind of baby stroller, the baby stroller frame that can vertically place after particularly a kind of the folding.

[background technology]

At present, the baby stroller frame of selling on the market with folder function, usually can only fold by fore-and-aft direction, promptly being provided with one between front support stand, bracket of rear mounting and hand push frame three can be with they three foldable structure that front and back fold successively, the volume of baby stroller frame at fore-and-aft direction can be reduced by behind this foldable structure folding, be convenient to transportation and deposit.Yet above-mentioned foldable structure, when front support stand and bracket of rear mounting are folded, front-wheel is liftoff and trailing wheel support ground, have only two trailing wheel support ground after folding, vertically not to be placed on the ground like this, can only place with lying low, convenient inadequately when putting like this, under above-mentioned background, the inventor has designed the utility model, since satisfy people's demand.

[utility model content]

The utility model has overcome the deficiency of above-mentioned technology, and a kind of baby stroller frame that can vertically place, put after folding easily with bracing or strutting arrangement is provided.

For achieving the above object, the utility model has adopted following technical proposal:

The baby stroller frame that can vertically place after a kind of the folding, two preceding support tubes that have front-wheel about it is characterized in that including, about two rear supporting tubes that have a trailing wheel and about two push tubes, support tube before described, rear supporting tube and push tube can before and after fold and make the liftoff and trailing wheel of front-wheel support ground, be provided with the preceding folding stand that to fold about them between described two preceding support tubes, be provided with the back folding stand that to fold about them between described two rear supporting tubes, be provided with about them the folding bracing or strutting arrangement that can support ground after together on two push tubes.

Described bracing or strutting arrangement include strut bar and about two dwangs, an end of two dwangs is hinged on the two ends of strut bar respectively, the other end of two dwangs is rotationally connected with the lower end that is arranged on two fixed drive bars on two push tubes respectively.

Be rotationally connected by barring gear between the lower end of described dwang and fixed drive bar, this barring gear includes and is arranged on the main hinged shaft that but fore-and-aft direction rotates on the fixed drive bar, be provided with the secondary hinge that can rotate perpendicular to the main hinged shaft rotation direction on main hinged shaft, described dwang is hinged on the secondary hinge.

On rear supporting tube, be provided with jack, be provided with the latch that can insert in the jack in the push tube bottom.

The front end of described two preceding support tubes bends inwards in opposite directions.

The beneficial effects of the utility model are:

When 1, using, with folding stand, back folding stand before the hand folding, with about two push tubes folding relatively, about two push tubes in folding relatively process, two fixed drive bars drive two dwang upper ends and relatively rotate, thereby make strut bar move down, up to the position that moves to support ground, this moment, two trailing wheels on this strut bar and support ground formed three support places, and the vehicle frame after whole like this folding just can stably vertically be placed on the ground.

2, novel structure of the present utility model designs ingenious.

[specific embodiment]

Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model: ginseng

Referring to Fig. 1-7, the utility model is the baby stroller frame that can vertically place after a kind of the folding, two preceding support tubes 2 that have front-wheel about it includes, about two rear supporting tubes 3 that have a trailing wheel and about two push tubes 4, support tube 2 before described, rear supporting tube 3 and push tube 4 can before and after fold and make the liftoff and trailing wheel of front-wheel support ground, be provided with the preceding folding stand 9 that to fold about them between described two preceding support tubes 2, be provided with the back folding stand 6 that to fold about them between described two rear supporting tubes 3, be provided with about them the folding bracing or strutting arrangement 1 that can support ground after together on two push tubes 4.Preceding folding stand 9 and back folding stand 6 structures are described in detail in the patent of the other a application that the applicant applies for simultaneously, are not described in this part patent.

Described bracing or strutting arrangement 1 include strut bar 11 and about two dwangs 12, one end of two dwangs 12 is hinged on the two ends of strut bar 11 respectively, and the other end of two dwangs 12 is rotationally connected with the lower end that is arranged on two fixed drive bars 7 on two push tubes 4 respectively.

Referring to Fig. 4-7, during use, with folding stand 9, back folding stand 6 before the hand folding, with about two push tubes 4 folding relatively, about two push tubes 4 in folding relatively process, two fixed drive bars 7 drive two dwang 12 upper ends and relatively rotate, thereby make strut bar 11 move down, up to the position that moves to support ground, this moment, two trailing wheels on this strut bar 11 and support ground formed three support places, and the vehicle frame after whole like this folding just can stably vertically be placed on the ground.

Be rotationally connected by barring gear 8 between the lower end of described dwang 12 and fixed drive bar 7, this barring gear 8 includes and is arranged on the main hinged shaft 81 that but fore-and-aft direction rotates on the fixed drive bar 7, be provided with the secondary hinge 82 that can rotate perpendicular to main hinged shaft 81 rotation directions on main hinged shaft 81, described dwang 12 is hinged on the secondary hinge 82.

On rear supporting tube 3, be provided with jack 31, be provided with the latch 41 that can insert in the jack 31, can realize the release of folding by the cooperation of latch 41 and jack 31 in push tube 4 bottoms.

The front end of described two preceding support tubes 2 bends inwards in opposite directions, be convenient to two front-wheels can folding and unfolding between two trailing wheels.
