preferably, upper rack posts, lower fulcrum bar rotate with the upper end of rear wheel support respectively and are connected.
according to a concrete aspect: the upper end of rear wheel support is fixed with attaching parts, upper rack posts, rotate respectively by the first pivot and the second pivot between lower fulcrum bar with attaching parts and be connected, rotated by the 3rd pivot between upper rack posts with push rod and be connected, handle rod and side handrail bar, to rotate with Wushu axle respectively by the 4th pivot between upper rack posts and be connected, side handrail bar is connected with being rotated by the 6th pivot between push rod, rotated by the 7th pivot between basket rod with lower fulcrum bar and be connected, rotated by the 8th pivot between basket rod with handle rod and be connected, and one of them also to be rotated with sliding part by the 9th pivot and is connected, or, basket rod, handle rod all to be rotated with sliding part by the 9th pivot and is connected.Further, the axial line of each described pivot parallels, and all along the left and right directions horizontal-extending of go-cart.
preferably, side handrail bar and handle rod are positioned at the inner side of push rod, upper rack posts and rear wheel support.
according to the utility model, described lockout mechanism can adopt conventional those in this area, is not particularly limited.
due to the enforcement of above technical scheme, the utility model compared with prior art tool has the following advantages:
the utility model go-cart adopts new folding principle, and whole car can be driven during push rod collapsed forward folding and support oneself, folding operation is simple, and volume after folding is little.

Detailed description of the invention
this example provides a kind of Foldable baby go-cart, its by have deployed condition and folded state trolley rack, form for trolley rack being locked in the lockout mechanism of deployed condition, front component and wheel assembly.The utility model improves and is the new foldable structure providing a kind of trolley rack.
as shown in Figures 1 to 6, trolley rack comprises in both sides and many cross bars 2,3,4 between symmetrically arranged side stand 1 and the side stand 1 being arranged on both sides and front grab rail 5.Side stand 1 comprises front-wheel support, rear wheel support 11, push rod 12, side handrail bar 13, handle rod 14 and basket rod 15.Front-wheel support is made up of upper rack posts 10a and lower fulcrum bar 10b.Front component 6, wheel assembly 7 are located at the bottom of lower fulcrum bar 10b and rear wheel support 11 respectively.Cross bar 2,3, the two ends of 4 are connected with the lower fulcrum bar 10b of both sides, the rear wheel support 11 of both sides, the push rod 12 of both sides respectively, and the two ends of front grab rail 5 are connected with the leading section of the side handrail bar 13 of both sides respectively.
the upper end of rear wheel support 11 is fixed with attaching parts 8, and rear wheel support 11 is provided with sliding part 9 slidably along its bearing of trend.
the bottom of upper rack posts 10a, the upper end of lower fulcrum bar 10b and attaching parts 8 rotate respectively by the first pivot A and the second pivot B and are connected, the upper end of upper rack posts 10a and the bottom of push rod 12 are rotated by the 3rd pivot C and are connected, handle rod 14 and side handrail bar 13 are rotated by the 4th pivot D and are connected, handle rod 14 and upper rack posts 10a are rotated by Wushu axle E and are connected, rotated by the 6th pivot F between side handrail bar 13 with push rod 12 and be connected, the 6th pivot F is positioned at the top of described 3rd pivot C.
rotated by the 7th pivot G between the leading section of basket rod 15 and the bottom of lower fulcrum bar 10b and be connected, the rear portion of basket rod 15, the bottom of handle rod 14 all to be rotated with sliding part 9 by the 9th pivot H and are connected, wherein, basket rod 15, handle rod 14 also can not simultaneously be connected on sliding part 9, as long as they two be connected to each other, and one of them is connected on sliding part 9.The axial line of each described pivot parallels, and all along the left and right directions horizontal-extending of go-cart.
as illustrated in fig. 1 and 2, when trolley rack is in deployed condition, upper rack posts 10a, lower fulcrum bar 10b and push rod 12 extend along same bearing of trend.Sliding part 9 is positioned at the top of rear wheel support 11, and time folding, sliding part 9 is along rear wheel support 11 slide downward.Handle rod 14 top has bending, and handle rod 14 is positioned at the front upper place of the point of connection of handle rod 14 and upper rack posts 10a with the point of connection of side handrail bar 13, and handle rod 14 is positioned at the front upper place of the point of connection of handle rod 14 and sliding part 9 with the point of connection of upper rack posts 10a.
this routine go-cart folding process is as follows: during unblock, promote push rod 12 to overturn forward, side handrail bar 13 is driven to travel forward, upper rack posts 10a moves downward, side handrail bar 13 and upper rack posts 10a sport simultaneously drives handle rod 14 with the point of connection (Wushu axle E) of itself and upper rack posts 10a for rotating in the center of circle, the rotation of handle rod 14 drives sliding part 9 along rear wheel support 11 slide downward, the slip of sliding part 9 can be drawn close to rear wheel support 11 with lower fulcrum bar 10b thus car load be folded, as illustrated in Figures 5 and 6, after folding, push rod 12, upper rack posts 10a and lower fulcrum bar 10b bends in zigzag, and rear wheel support 11 is between upper rack posts 10a and lower fulcrum bar 10b, folding volume is little.
therefore the utility model folding operation is very simple, and volume after folding is little, can support oneself.
above the utility model is described in detail; its object is to allow the personage being familiar with this art can understand content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
