Portion rotationally connects on the lower part of present pocket bracket 6.
Specifically, fore-stock 1 includes two groups of front support rods 11 for being divided into the left and right sides, and every group of front support rod 11 is from front to back
Gradually inclination extends ground setting upwards, and the lower part of every group of front support rod 11 is equipped with front-wheel 10；After-poppet 2 includes being divided into left and right two
Two groups of back stays 21 of side, the rear transverse rod 21 being connected between two groups of 21 lower parts of back stay, every group of back stay 21 is from back to front
Gradually inclination extends ground setting upwards, and the lower part of every group of back stay 21 is equipped with rear-wheel 20；Push-rod frame 3 includes being divided into left and right two
The push rod of side, the push rod of every side include the lower push-rod 31 and upper push-rod 32 being rotatablely connected by push rod locking piece 33, wherein two
The upper push-rod 32 of side is wholely set U-shaped bar.On each side in the left and right of vehicle frame 100, under the top of front support rod 11 and lower push-rod 31
Portion is connected to the top of back stay 21 by different shafts respectively.
Seat pocket frame 200 is arranged in left-right direction between front support rod 11, back stay 21 and the push rod of two sides, seat pocket bracket 6
With two groups at left and right sides of being divided into, herein, seat pocket bracket 6 is in direct rod shape, along the length extending direction of back stay 21
It is connected to lower slider on back stay 21.Herein, the guide chute 23 vertically extended, seat pocket are offered on back stay 21
The lower part of bracket 6 is provided with sliding part 61, which is threaded through in guide chute 23 with being slidably matched, to provide a pocket
Guiding when bracket 6 is slided up and down along after-poppet 2.
Front rod 4 and back link 5 correspondingly also have two groups for being divided into the left and right sides, and front rod 4 is connected to front support rod
Between 11 and seat pocket bracket 6, back link 5 is connected between lower push-rod 31 and seat pocket bracket 6, herein, front rod 4 and back link 5
The lower part of present pocket bracket 6 is rotationally connected around same rotation centerline.
In the present embodiment, for seat pocket frame 200 also to be collapsibly arranged, peripheral frame frame includes upper enclosure frame 8 and lower enclosure frame 7, under
The top on the top of peripheral frame 7, the lower part of upper enclosure frame 8 and seat pocket bracket 6 locks joint 9 by seat pocket and is rotationally connected to one
It rises.When seat pocket frame 200 folds, upper enclosure frame 8, lower enclosure frame 7 and seat pocket bracket 6 are mutually rotated and are close together.
Referring to shown in Fig. 1, Fig. 2, when children trolley is in unfolded state, vehicle frame 100 is unfolded respectively with seat pocket frame 200,
The top of seat pocket bracket 6 extend out to the top of after-poppet 2, so that the seat pocket peripheral frame of seat pocket frame 6 is in higher height and position, with
The support of infant higher position is provided.
It is shown in Figure 3 when needing to fold up the children trolley, seat pocket frame 200 is given into folding first, specifically
For upper enclosure frame 8, the rotation of lower enclosure frame 7 are collapsed and collapse it with respect to seat pocket bracket 6 together；Then, shown in Figure 4, it will
Upper push-rod 32 relative to lower push-rod 31 rotate collapse, and drive push-rod frame 3 to be turned over and make its relative to after-poppet 2 rotate and gradually
It collapses, under the drive of back link 5, seat pocket bracket 6 drives front rod 4 to rotate and drive preceding branch along 2 slide downward of after-poppet
Frame 1 is gradually rotated relative to after-poppet 2 and is collapsed.Until fore-stock 1, after-poppet 2 and push-rod frame 3 are mutually drawn close along the longitudinal direction, seat
Pocket bracket 6 also slides down to lowest position along after-poppet 2, so that folded seat pocket frame 200 and fore-stock 1, after-poppet 2
And push-rod frame 3 mutually collapses together, as shown in Figure 5.Under the folded state, the top of seat pocket bracket 6 and the top of after-poppet 2
It is mutually flush, so that folded seat pocket frame 200 fully collapses among each rod piece of vehicle frame 100, efficiently reduces
The virgin folded volume of cart.
It is when needing to be unfolded the children trolley, then substantially opposite with operation when folding, specifically, push-rod frame 3 is pulled to make
It is rotated relative to after-poppet 2 is unfolded, so that back link 5 drives seat pocket bracket 6 along 2 upward sliding of after-poppet, and passes through front rod 4
So that fore-stock 1 gradually rotates expansion with respect to after-poppet 2.After vehicle frame 100 is fully deployed, seat pocket bracket 6 is with respect to after-poppet 2
Sliding is increased to extreme higher position, and finally the seat pocket peripheral frame on seat pocket frame 200 is unfolded again.Opening operation is also very convenient.
Embodiment 2
Referring to attached children trolley shown in fig. 6, embodiment 1 is compared, difference essentially consists in expansion and folding and the seat of vehicle frame 100
Sliding up and down for pocket bracket 6 does not link, the height of seat pocket frame 200 can independently of vehicle frame 100 expansion and folding and into
Row adjustment.In the case where vehicle frame 100 is in unfolded state, user can the individually height of adjusting seat pocket bracket 6 as needed, thus
So that the seat pocket peripheral frame on seat pocket frame 200 is adjusted to different height and positions.
Specifically, vehicle frame 100 includes fore-stock 1, after-poppet 2 and the push-rod frame 3 being mutually rotatablely connected, 6 edge of seat pocket bracket
Up and down direction is slidably arranged on after-poppet 2, and the length extending direction of back stay 21 is slidably set specially along after-poppet 2
In on back stay 21, the bracket lock for being locked in the two under multiple gears is provided between back stay 21 and seat pocket bracket 6
Determine part (not shown), the unblock button 62 for being unlocked to the bracket locking piece is additionally provided on seat pocket bracket 6.
In the case where vehicle frame 100 is in the open state, user can unlock bracket locking piece by being unlocked by pressing button 62, then root
According to needing to come height and position of the adjusting seat pocket bracket 6 with respect to back stay 21, seat pocket frame 200 is adjusted to the height position of needs
It sets；When needing to fold up children trolley, then first seat pocket frame 200 is folded, then makes a pocket bracket 6 along after-poppet 2
Lowest position is slided down to, it is collapsed as best one can in height with after-poppet 2, is then again folded vehicle frame 100,
So that folded seat pocket frame 200 collapses between each rod piece of vehicle frame 100.
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.
