13 are pivotally connected on lower push-rod 31, and its underpart is connect by rotation axis 11 with the posterior rotation of front support rod 1a, and rotation axis 11
In the rear of sliding guide piece 22.Lower push-rod 31, front support rod 1a, the variable triangle knot of a bottom edge side length is formed between pull rod 4
Structure.Opposite sliding by front support rod 1a with respect to sliding guide piece 22, realizes fore-stock 1 and the exhibition of after-poppet 2 along the longitudinal direction
Open and folding and push-rod assembly 3, pull rod 4 with respect to fore-stock 1, after-poppet 2 opening and folding.
Referring to connecting rod 5 shown in each attached drawing, is additionally provided on each side in the left and right of vehicle frame, the one end of connecting rod 5 passes through the 4th axis 14
It is rotationally connected on pull rod 4, is rotationally connected between the other end of connecting rod 5 and the lower end of upper push-rod 32 by the 6th axis 16
It connects, wherein the 6th axis 16 is located at the lower section of the 5th axis 15 on upper push-rod 32.
Referring to shown in each attached drawing, the seat bar 6 extended along the longitudinal direction, this bar 6 are additionally provided on each side in the left and right of vehicle frame
Rear portion be rotationally connected on connecting rod 5 by the 7th axis 17, the front of seat bar 6 can either relatively rotate and can be along from height
Degree direction is opposite to be slidably connected on lower push-rod 31.Specifically, it is rotationally connected with sliding part 7 on lower push-rod 31, slided herein
It is sliding sleeve that moving part 7, which uses, which is slidably arranged on present bar 6 along the length extending direction of seat bar 6.Wherein, sliding sleeve 7 exists
It is located at the top of third axis 13 on lower push-rod 31.
Referring to shown in Fig. 1, Fig. 2, the children trolley of the present embodiment is under unfolded state, and fore-stock 1 is with after-poppet 2 along preceding
Rear direction expansion, forms stable support underframe, and push-rod assembly 3 is vertically extended with pull rod 4, and the setting of seat bar 6 pushes away under
Stable sitting support is provided between bar 31 and connecting rod 5.
When needing to fold the children trolley, referring to shown in Fig. 3, Fig. 4, upper push-rod 32 is pushed to turn over it with respect to lower push-rod 31
Turn, and make lower push-rod 31 downwardly after-poppet 2 gradually overturns and draws close, connecting rod 5, pull rod 4 drive under, upper push-rod 32,
Lower push-rod 31, connecting rod 5, seat bar 6, pull rod 4 along the vertical direction gradually with after-poppet 2 collapse, and fore-stock 1 slide backward and gradually
It is collapsed along the longitudinal direction with after-poppet 2, the spacing between front-wheel 10 and rear-wheel 20 along the longitudinal direction reduces, and gradually realizes vehicle frame
Whole folding.
Folded vehicle frame is as shown in Figure 5, Figure 6, and upper push-rod 32, lower push-rod 31, connecting rod 5 and the stacking of pull rod 4 are collapsed preceding
The top of bracket 1 and after-poppet 2, each rod piece closely collapse together, the very flat structure of presentation, on front-rear direction
Size substantially shortens, and folding rear carriage overall dimensions reduce.
Conversely, to open the children trolley in use, only needing to pull up upper push-rod 32, can make lower push-rod 31,
Connecting rod 5 and the linkage expansion of pull rod 4, and fore-stock 1 is unfolded along the longitudinal direction with respect to 2 forward slip of after-poppet, realize vehicle
The opening of frame and for using, operate also very convenient.
Embodiment 2
Referring to children trolley shown in Fig. 7 to Figure 12, it is with the main distinction of embodiment 1, it is few in the vehicle frame of the present embodiment
Connecting rod 5 and seat bar 6.It when folding, needs first to fold push-rod assembly 3, i.e., first turns over upper push-rod 32 with respect to lower push-rod 31
It after turning folding, then drives entire push-rod assembly 3 to rotate backward and so that it is increasingly towards the overturning of after-poppet 2 and draw close, can make drawing
Bar 4 drives fore-stock 1 to slide backward and gradually collapse along the longitudinal direction with after-poppet 2, along preceding between front-wheel 10 and rear-wheel 20
The spacing of rear direction reduces, and gradually realizes the whole folding of vehicle frame.
To sum up, children trolley of the invention, rod piece quantity is few, and structure is simple, folds and expansion operation is all very convenient, folding
The anteroposterior dimension of poststack vehicle frame shortens, and overall structure is flat, brings convenience for the daily storage and carrying use of user.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
