Specific embodiment
As shown in Figures 1 to 9, a kind of children trolley described in the utility model, including vehicle frame, the youngster being arranged on vehicle frame
Virgin seat pocket, the front component 40 for being arranged on vehicle frame front portion and the wheel assembly for being arranged on vehicle frame rear portion.The vehicle frame includes front-wheel
Support 10, rear wheel support 20 and push rod 30.The top of the front-wheel support 10 is connected with each other with the top of rear wheel support 20, it is described before
The bottom of wheel support 10 is connected with front component 40.The push rod 30 is installed in the top of front-wheel support 10 and rear wheel support 20.
The wheel assembly includes symmetrically being arranged on that the left rear wheel 1 and off hind wheel 2 of vehicle frame both sides and connection are left
The hind axle 3 of trailing wheel 1 and off hind wheel 2.The hind axle 3 is located in the bottom of rear wheel support 20 and stretches out in rear wheel support 20
The left and right sides.The hind axle 3 can rotate on rear wheel support 20 along Pivot Point Center line.The left and right two ends of the hind axle 3
It is fixedly connected with left rear wheel 1 and off hind wheel 2 respectively by installing fixation kit.
The off hind wheel 2 of the left rear wheel 1/ includes wheel hub 7 and spoke 4.The spoke 4 is propped up respectively along linear extension and its two ends
Support is fixed in the inner ring of wheel hub 7, and the spoke 4 is by the wheel subcenter of 1/ off hind wheel of left rear wheel 2.
The fixation kit of installing includes the sliding part 5 and locking piece 6 that are slidably disposed on spoke 4.The present embodiment
In, the sliding part 5 is set on spoke 4 and can be slided along the bearing of trend of spoke 4.Connection is extended with the sliding part 5
Pin 51, the two ends of the hind axle 3 have the connecting pin bores coordinated with connecting pin 51（It is not shown）.The insertion of the connecting pin 51 connects
Hind axle 3 is set to be fixed with left rear wheel 1 and off hind wheel 2 in pin hole.
The sliding part 5 has multiple latched positions on spoke 4, and the locking piece 6 can be incited somebody to action in any latched position
Sliding part 5 is locked on spoke 4.
Locking piece 6 can have various implementations.One of which is achieved in that：The locking piece 6 includes bolt, described
On spoke 4 multiple screwed holes 41 are offered along the bearing of trend of spoke 4.When sliding part 5 reaches any latched position, the spiral shell
Bolt can be threadedly coupled with corresponding screwed hole 41 through sliding part 5 and sliding part 5 is locked on spoke 4.
Another kind is achieved in that：The locking piece 6 includes stop pin, is opened along the bearing of trend of spoke 4 on the spoke 4
It is provided with multiple pin-and-holes 42.When sliding part 5 reaches any latched position, the stop pin can pass through sliding part 5 and insert right
Sliding part 5 is locked on spoke 4 in the pin-and-hole 42 answered.
Certainly, locking piece 6 can also have other structures, due to its not this patent emphasis, not launch to repeat herein.
Said structure sets and causes that there are the hind axle 3 multiple installation fixing positions to put on the off hind wheel 2 of left rear wheel 1/.Institute
Multiple installation fixing positions are stated to put including concentric position and eccentric position.The left rear wheel 1 and off hind wheel 2 have positioned at wheel respectively
The wheel subcenter line at center.When hind axle 3 is in concentric position, in axial line, the wheel of left rear wheel 1 of the hind axle 3
The wheel subcenter line of heart line and off hind wheel 2 is conllinear.This when, children trolley is in conventional working condition, that is, promote children
Go-cart, children trolley can smoothly move ahead on the ground, vehicle frame lower motion supreme with respect to ground.
When hind axle 3 is in eccentric position, the wheel subcenter line of the left rear wheel 1 and the wheel subcenter line of off hind wheel 2
It is conllinear and with the axis parallel of hind axle 3.I.e. after the wheel subcenter line of the axial line of hind axle 3 and the left rear wheel 1 and the right side
The wheel subcenter line of wheel 2 is in non-colinear state.The sliding part 5 is in the eccentric position of the off hind wheel 2 of left rear wheel 1/.At this
When carrying out children trolley advance under state, left rear wheel 1 and off hind wheel 2 are moved ahead and can be driven by hind axle 3 in ground surface
Vehicle frame rear portion is moved up and down, and then vehicle frame drive baby seat pocket is waved and rocked.
The sliding part 5 has multiple latched positions on spoke 4, and corresponding hind axle 3 also has multiple eccentric positions.
When the sliding part 5 is locked in latched positions different on spoke 4, after the axial line of the hind axle 3 and the right side of left rear wheel 1/
The distance between wheel subcenter of wheel 2 is also different.The axial line of the hind axle 3 and the wheel subcenter of the off hind wheel 2 of left rear wheel 1/
The distance between it is more long, drive the amplitude waved of seat pocket bigger vehicle frame when children trolley advances is carried out.User can basis
Latched position of the demand selection sliding part 5 of oneself on spoke 4, so as to obtain the seat pocket amplitude of fluctuation of needs.
It can be seen that, the present embodiment also add implementation children outside the working method that the conventional steady implementation of children trolley is advanced
Go-cart moves ahead and drives the working method waved of seat pocket.Under the working method, carry out children trolley and move ahead, the off hind wheel of left rear wheel 1/
2 roll through hind axle 3 on the ground drives whole vehicle frame to move up and down, and then the children being sitting in a pocket is being carried out
During there is the sense learning through practice that waves of fluctuating, the use that increased children trolley is interesting, recreational.
In addition, when hind axle 3 is in eccentric position, user can be made with front and rear reciprocating sliding children trolley back and forth
Seat pocket front and rear can fluctuate and wave, and this just makes children trolley be provided with the function of rocking chair/shaking table.
As described above, we are illustrated fully according to objective of the present utility model, but the utility model not limits to
In above-described embodiment and implementation.The practitioner of correlative technology field can be in the scope of technological thought of the present utility model license
Inside carry out different changes and implementation.
