Description
Technical field
The present invention relates to a kind of folding children's barrow.
Background technology
Folding children's barrow is mainly realized by the go-cart vehicle frame that setting has open mode and a folded state.For the function that realizes folding, the setting that is rotationally connected mutually between the parts such as the major part of composition go-cart vehicle frame such as front-wheel support, rear wheel support, side handrail, pulling handle rod, concrete structure design then is varied.Convenient folding, the folding volume children trolley little and that cost is low of design is the target that the go-cart designer is pursued, and also is to make the go-cart product have the key of the market competitiveness simultaneously.
In the prior art, be 200720041695.3 the disclosed folding children's barrow of utility model patent as the patent No., though have folding little advantage, the cart structure complexity, rod member is many, and cost is higher; Though and some commercially available children trolley rod member is less, fold up quite loaded down with trivial details and also volume after folding bigger again.
Summary of the invention
Technical matters to be solved by this invention provides folding, the folding children trolley that volume is little and cost is low of a kind of convenience.
For solving above technical matters, the present invention adopts following technical scheme:
A kind of folding children's barrow, comprise go-cart vehicle frame with deployed condition and folded state, be used for the lockout mechanism of go-cart bracket locked in deployed condition, wherein the go-cart vehicle frame comprises and is positioned at the symmetrical side stand in both sides, be arranged on the seat between the two described side stands, described side stand comprises front-wheel support, rear wheel support and pulling handle rod, the upper end of rear wheel support, the bottom of pulling handle rod all rotates with the rearward end of front-wheel support and is connected, two described side stands are connected by the cross support that is arranged between them, its length direction of front-wheel support upper edge is provided with sliding part slidably, the cross support is intersected by first rod member and second rod member and connects and composes at the infall phase pivot, two leading sections of cross support rotate by first rotary joint with sliding part respectively and are connected, two rearward end rotate by second rotary joint with two side stands respectively and are connected, and the bottom of pulling handle rod rotates with described sliding part by head rod and is connected.
Advance embodiment preferred as the present invention: the rearward end of front-wheel support is provided with the adapter sleeve of the upper end of the bottom that is used to connect pulling handle rod and rear wheel support, two rearward end of cross support rotate with adapter sleeve respectively and are connected, and the rearward end of seat bar is arranged on the adapter sleeve rotationally.
The upper end of described rear wheel support is fixedly connected by second pipe link and described sliding part, the rearward end that constitutes the seat bar of described seat sidepiece rotates with side stand and is connected, its length direction of seat bar upper edge is provided with sliding sleeve slidably, and this sliding sleeve also rotates with the head rod of homonymy simultaneously and is connected.
Be provided with at least one folding stull between two rear wheel supports.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
1, but the go-cart vehicle frame is in horizontal and vertical all foldings, and folding volume is little;
2, forwards promote pulling handle rod, then children trolley is simultaneously in horizontal and vertical folding, and folding operation is easy;
3, car load is provided with simply, rod member is less, and cost is low.

The specific embodiment
Extremely shown in Figure 6 as Fig. 1, the front component 13 and the wheel assembly 14 at front portion and rear portion, the end at the bottom of the folding children's barrow of present embodiment comprises the go-cart vehicle frame and is arranged on the go-cart vehicle frame.When go-cart is not used, can fold and pack up, thereby reduce to take up room and be convenient for carrying; In use, be in stable deployed condition by the lockout mechanism locking.
See Fig. 1, being provided with of go-cart vehicle frame is simple, and rod member is few.See Fig. 3, the go-cart vehicle frame at left and right directions (laterally) and fore-and-aft direction (vertically) but all foldings, volume after folding is little.Have above-mentioned advantage the go-cart vehicle frame specifically be provided with as follows:
The go-cart vehicle frame mainly comprises at the side stand of both sides and is arranged on seat between two side stands.
Described side stand comprises that front-wheel support 1, bottom that the bottom is provided with front component 13 are provided with rear wheel support 2, the pulling handle rod 3 of wheel assembly 14.The rearward end of front-wheel support 1 is set with adapter sleeve 9, be provided with the upper end of rear wheel support 2 and the bottom of pulling handle rod 3 simultaneously at adapter sleeve 9 places, the bottom of the upper end of rear wheel support 2, pulling handle rod 3 is all relative with the rearward end of front-wheel support 1 to be connected rotationally, and the lockout mechanism (not shown) of these three parts of locking is set in the position, lockout mechanism can not be described in detail at this for any known manner that realizes lock function.So, pulling handle rod 3 and rear wheel support 2 can rotate relative to front-wheel support 1 when lockout mechanism is in released state, thus vertically folding.
The important improvement part of present embodiment also is to be connected by cross support 5 between the side stand of both sides.Cross support 5 is intersected by first rod member 50 and second rod member 51 and connects and composes at the infall phase pivot, its length direction is provided with sliding part 6 slidably in front-wheel support 1 upper edge, the leading section of first rod member 50 and second rod member 51 rotates by first rotary joint 10 with sliding part 6 respectively and is connected, and their rearward end rotates with described adapter sleeve 9 by second rotary joint 11 respectively and is connected.In addition, between two rear wheel supports 2, be provided with folding stull 12.Being arranged under the prerequisite that guarantees vehicle frame stability of cross support 5 and stull 12 makes that open along with opening of cross support 5 by folding along with the folding of cross support 5 and stull 12 for two side stands, thereby makes the go-cart vehicle frame laterally collapsible.
As shown in the figure, between the bottom of pulling handle rod 3 and sliding part 6, also be rotatably connected to head rod 7, thereby when promoting pulling handle rod 3, thrust is on sliding part 6 and finally drive 5 foldings of cross support.Meanwhile, be rotatably connected to second pipe link 8 between rear wheel support 2 and the sliding part 6, therefore, during to front slide, rear wheel support 2 promptly can be packed up towards the direction of front-wheel support 1, and reaches folded state as shown in Figure 5 at last at sliding part 6.
The seat is a pith of children trolley, and the seat of a lot of children trolleys can't fold.And in the present embodiment, as shown in Figure 3, the seat bar 4 of forming the both sides at seat can folding.The rearward end of seat bar 4 rotates with adapter sleeve 9 and is connected, its length direction of seat bar 4 upper edges is provided with sliding sleeve 15 slidably, and this sliding sleeve 15 also rotates with the head rod 7 of homonymy simultaneously and is connected, so, when forwards slide in the bottom of head rod 7, seat bar 4 moves downward and folding.
More than the present invention has been done detailed description.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Specification sheets and accompanying drawing should be considered to illustrative and be nonrestrictive.
