Specific implementation mode
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, the cart of the utility model includes：Push rod 11, fore-stock 12, the after-poppet being symmetrical set
13, side connecting rod 14, wherein the upper end of fore-stock 12 and side connecting rod 14 and lower end pin joint, lower end and the after-poppet 13 of push rod 11 are sold
It connects, the first connection unit is rotatably connected between two after-poppets 13, which further includes：The slide link being symmetrical set
15, sliding sleeve 16, sliding sleeve 16 are arranged on after-poppet 13 and are slided along after-poppet 13, the both ends of slide link 15 respectively with side connecting rod
14 and 16 pin joint of sliding sleeve.
Specifically, after-poppet 13 is equipped with the front-wheel seat 17 with the lower end pin joint of fore-stock 12；The lower end of push rod 11 is equipped with
The push rod joint 19 that one end is connect with the upper end of the lower end pin joint of push rod 11, the other end and fore-stock 12.
In addition, the utility model is equipped with handrail 18 in the upper end of two push rods 11, and when cart is folded state, two
A handrail 18 distinguishes closely two front-wheel seats 17.Setting handrail 18, which facilitates, carries out the cart, and adds handrail 18 and do not have an impact
Size after cart folding.
Carry out the cart to further facilitate, a handle 21 can be also rotatablely connected between the upper end of two push rods 11,
And 21 middle part of handle is equipped with the axle portion 22 that it can be made to be converted into centre.In this way, to applying downward effect among handle 21
Power, handle 21 can be equivalent to centre.
Specifically, the first connection unit in the utility model includes two bottom bracings 31 for intersecting pivot joint, two bottom bracings 31
Four ends be rotatablely connected respectively with two front-wheel seats 17 and two sliding sleeves 16.In this way, when being rotated at each pin joint, pass through cunning
Dynamic connecting rod 15 drives two bottom bracings 31 to intersect rotation with sliding sleeve 16, and folding or opening up for cart is realized in the intersection rotation of two bottom bracings 31
It opens.
The cart of the utility model further includes the second connection unit, and the second connection unit is for enhancing the solid of the cart
Degree, the second connection unit include two preceding supports 41 for intersecting pivot joint, and the opposite both ends of 41 two of which are supportted before two respectively with two
The rotation connection of a front-wheel seat 17, other two opposite both ends are rotatablely connected with two side connecting rods 14 respectively；And support 41 before two
A bar 42 is rotatably connected on the both ends being rotatablely connected respectively with two side connecting rods 14, seat bar 42 is used for playing a supportive role, and is
The support for enabling a bar 42 to stablize, the utility model are rotatably connected on two fore-stocks 12 and are slidably socketed with seat bar 42
Guide sleeve 43, during folding, seat bar 42 can move cart relative to guide sleeve 43, in this way, after cart folds, seat bar 42 is with before
Holder 12 is parallel, it is ensured that the form after cart folds is smoothly smooth.
In order to ensure the cart folds, rear form is more smooth smooth, and the utility model is by side connecting rod 14 and after-poppet 13
It is set at pin joint between front-wheel seat 17 and sliding sleeve 13.
In addition, the wheel of the cart of the utility model is mounted on the both ends of each after-poppet 13, respectively front-wheel 51 and trailing wheel
52。
The equivalent process of the cart of the utility model is as shown in Figures 2 and 3, specifically, first making push rod 11 around push rod joint 19
Rotation, because of side connecting rod 14 and 11 pin joint of push rod, makes 14 stress of side connecting rod, side connecting rod 14 make slide link in 11 rotation process of push rod
15 are slided by sliding sleeve 16 on after-poppet 13, and sliding sleeve 16 drives two bottom bracings 31 to intersect rotation, makes the branch at 31 both ends of each bottom bracing
Frame is drawn close to centre, while being supportted 41 before making two and being intersected rotation, and handle 21 is equivalent to centre, and each pipe fitting continues to draw close to centre,
Finally by the fold of push rod 11 on fore-stock 12, you can be converted into state shown in Fig. 3.As it can be seen that the folding of the cart of the utility model
Conjunction mode can effectively reduce width, length and volume, and the form after folding is smoothly smooth, occupies little space.
The technical principle of the utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein,
Those skilled in the art would not require any inventive effort the other specific implementation modes that can associate the utility model,
