The trailing wheel 30 of the bottom of after-poppet 3.
Push rod 1 is along the folding setting in its length direction, including upper push-rod 11, top and upper push-rod 11 rotate connection
Lower push-rod 12, the push rod locking piece 13 between upper push-rod 11 and lower push-rod 12, herein push rod locking piece 13 is located at upper
Electric bell at push rod 11 and the switching of lower push-rod 12.
The top of fore-stock 2 rotates with the top of after-poppet 3 and is connected, and seat bar 4 extends along the longitudinal direction, before seat bar 4
Portion is rotationally connected on push rod 1 by first axle 41, and the rear portion of seat bar 4 is rotationally connected to after-poppet 3 by the second axle 42
On, sliding part 6 is rotationally connected with by the 3rd axle 43 on seat bar 4, the 3rd axle 43 is present on bar 4 and is located at first axle 41 and the
Between two axles 42.Sliding part 6 is slidingly disposed on fore-stock 2 along the length bearing of trend of fore-stock 2.Sliding part 6 can be adopted
Slide block 61 as shown in Figure 6, arranges the sliding rail slided up and down for slide block 61 on fore-stock 2；Sliding part 6 can also be adopted
With sliding sleeve 62 as shown in Figure 7, sliding sleeve 62 is slidably set on fore-stock 2.
The upper end of strut 5 is rotationally connected on push rod 1, and strut 5 is located at first with the transit point of push rod 1 on push rod 1
The top of axle 41, herein, the lower end of strut 5 is rotationally connected on lower push-rod 12 with the front portion of seat bar 4；The lower end of strut 5
Rotationally it is connected at least one of fore-stock 2 and after-poppet 3 part.In the present embodiment, the lower end of strut 5, fore-stock 2
Top, the top of after-poppet 3 be rotationally connected with same place, between push rod 1, seat bar 4, fore-stock 2, strut 5 constitute four connect
Linkage, triangle structure between fore-stock 2, after-poppet 3 and seat bar 4.
In the present embodiment, locking mechanism is located between sliding part 6 and fore-stock 2, before sliding part 6 is locked in
On support 2, when sliding part 6 and fore-stock 2 are fixed, above-mentioned quadric chain, above-mentioned triangular structure can be at stable
State.During setting, locking mechanism can be set to the form that lock pin is engaged with lockhole, i.e., fore-stock 2 and sliding part 6 this two
Lock pin is set on a part in individual part, arranges what is inserted with being available for above-mentioned lock pin corresponding matching on another part
Lockhole, certain locking mechanism may also be employed other structures form.
In the present embodiment, stroller frame have positioned at both sides side stand, per side side stand include fore-stock 2, after
Support 3 and seat bar 4, are connected with cross bar 7 between the side stand of both sides, the cross bar 7 located at both sides fore-stock 2 top between or
Between the top of both sides after-poppet 3, cross bar 7 is provided with unlocking knob 8, and linkage is arranged between unlocking knob 8 and locking mechanism
Part, so as to unlock locking mechanism when unlocking knob 8 is rotated, facilitates the folding operation of go-cart.Here, can be in unblock rotation
Locking piece in button 8 and locking mechanism（Such as lock pin）Between hauling rope is set, rotate unlocking knob 8 when by hauling rope drive

It is fixed, constitute stable quadric chain between push rod 1, fore-stock 2, seat bar 4 and strut 5, and fore-stock 2, after-poppet 3, seat bar 4
Between form stable triangle mechanism.
It is shown in Figure 3 when needing to fold the stroller frame, push rod 1 can along its length be folded first, will
Unlock as the electric bell of push rod locking piece 13, upper push-rod 11 is overturn forward so as to close up folding with respect to lower push-rod 12.Then, such as
Shown in Fig. 4, unlocking knob 8 is rotated so that locking mechanism is unlocked, the relative fore-stock 2 of sliding part 6 slidably, is now promoted forward
Push rod 1, or cross bar 7 has been carried, under thrust or under the Action of Gravity Field of push rod 1, push rod 1 travels forward, and drives seat bar 4
Front portion moves forward, and sliding part 6 drives after-poppet 3 to draw in forward towards fore-stock 2 along the slide downward of fore-stock 2, while driving
Relatively rotate between each rod member in quadric chain and mutually draw close, finally cause push rod 1, seat bar 4, fore-stock 2, strut 5 and
After-poppet 3 mutually draws in, forms folded state as shown in Figure 5.Under the state, front-wheel 20 is supported in ground jointly with lower push-rod 12
Face and cause the stroller frame after folding from standing on ground.
When need open stroller frame when, then first by upper push-rod 11 relative to lower push-rod 12 rotate and so that push rod 1 launches simultaneously
Push rod locking piece 13 is locked, push rod 1 is then pulled back, push rod 1 drives the front portion of seat bar 4 to move backward, so as to drive cunning
Along the upward sliding of fore-stock 2, each rod member in quadric chain is mutually rotated and launched relatively moving part 6, while after seat bar 4 drives
Away from the back rotation of fore-stock 2, relative fore-stock 2 launches support 3.Until mutually launch between each rod member, or sliding part 6
When sliding into the latched position on fore-stock 2, locking mechanism locking, stroller frame can be at stablizing in deployed condition, such as scheme
1st, shown in Fig. 2.
To sum up, children trolley of the invention, its simple structure, rod member negligible amounts are folded very simple with expansion operation
Convenient, the stroller frame after folding can certainly stand on ground in flat structure, its compact conformation, small volume.
Above-described embodiment technology design only to illustrate the invention and feature, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implement according to this, can not be limited the scope of the invention with this.It is all according to the present invention
Equivalence changes or modification that Spirit Essence is made, all should be included within the scope of the present invention.
