The other end is connected with the front-wheel connector.
Further, the telescopic direction of the compression spring is identical with the extending direction of the sliding slot.
Preferably, the distance between the roller lower edge and the front-wheel lower edge are not more than the four of the preceding wheel diameter
/ mono-.
Preferably, front-wheel of the children trolley per side includes two wheels, the roller be located at two wheels it
Between.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：The children of the present invention
Cart structure is simple, and handle need not be pushed when encountering barrier in children trolley traveling process, normal to carry out that front-wheel is made
Clear the jumps, it is time saving and energy saving, it is very easy to use.
Brief description of the drawings
Attached drawing 1 is one of structure diagram of children trolley of the present invention；
Attached drawing 2 is the second structural representation of the children trolley of the present invention；
Attached drawing 3 is partial enlarged view at A in attached drawing 1（Remove front-wheel）；
Attached drawing 4 is phantom at A in attached drawing 1（Enlarged drawing, removes front-wheel）.
Embodiment
Technical scheme is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 1 ~ Fig. 4, children trolley of the invention includes stroller frame and is arranged on the bottom front portion of stroller frame
Front component, front component include front-wheel connector 1, front-wheel 2 and roller 3, and front-wheel connector 1 is connected with stroller frame, and front-wheel 2 can
It is rotatably arranged on front-wheel connector 1, roller 3 can be rotatably arranged on front-wheel connector 1.
The leading edge of roller 3 is located at the front of the leading edge of front-wheel 2, and the lower edge of roller 3 is located at the lower edge of front-wheel 2
Top, and the distance between lower edge of the lower edge of roller 3 and front-wheel 2 is not more than a quarter of the diameter of front-wheel 2, at the very moment
When virgin cart runs into the barrier on ground, roller 3 first with bar contact so that roller 3 rotates, and drives front-wheel 2 to raise
So that front-wheel 2 clears the jumps.To allow front-wheel more easily to clear the jumps, or cross of a relatively high obstacle
Thing, roller 3 can be slidably arranged on front-wheel connector 1, and at this time, when children trolley runs into barrier, roller 3 is in rotation
During 1 upward sliding of opposing front wheels connector at the same time so that front-wheel 2 can further be raised and more convenient cleared the jumps.
A kind of specific embodiment, is equipped with sliding slot 11 on front-wheel connector 1, and roller 3 is rotationally set by roller shaft 4
On front-wheel connector 1, sliding slot 11 tilts extension from bottom to top from front to back on front-wheel connector 1, and roller shaft 4 is threaded through sliding slot 11
In and can be slided along the extending direction of sliding slot 11, when children trolley on flat road surface when driving, roller shaft 4 is located at sliding slot
11 bottom.When children trolley is encountering barrier during traveling, still normally carry out children trolley, such roller 3 is first
First it is against on barrier, the normal active force for carrying out children makes roller 3 be rolled along barrier after being delivered on roller 3, drives at the same time
Make the upward sliding in sliding slot 11 of roller shaft 4, so that front-wheel 2 is raised, and can make front-wheel after front-wheel 2 is raised to a certain degree
2 clear the jumps, such mode for crossing barrier of the front-wheel 2 of children trolley, are not required to push the handle of children trolley, time saving province
Power, it is very easy to use.
The children trolley be additionally included in children trolley front-wheel 2 clear the jumps after be used for make roller shaft 4 reset reset
Element 5, in the present embodiment, reset element 5 uses compression spring, which is also disposed in sliding slot 11 and positioned at the top of roller shaft 4,
The telescopic direction of compression spring is identical with the extending direction of sliding slot 11, which, which further includes, can be slidably arranged in sliding slot 11
Sliding block 6, roller shaft 4 is fixedly connected with sliding block 6, and the one end of compression spring is fixedly connected on sliding block 6, and the other end is fixedly connected
On front-wheel connector 1.During children trolley clears the jumps during traveling, roller shaft 4 is upward in sliding slot 11
Compressed compression spring during slip, after front-wheel 2 clears the jumps, the power acted on roller 3 disappears, and roller shaft 4 is in compression spring
Resetted under the action of elastic force along 11 slide downward of sliding slot.In addition, before can also reducing children trolley by the setting of compression spring
Wheel 2 is in the caused impact endurance test shock during clearing the jumps to resting on the influence of the children in children trolley.
A kind of specific embodiment, the front-wheel 2 of every side of the children trolley include two wheels, and roller 3 is located at two
Between wheel, the middle position that two wheels are located at when roller 3 is optimal.
In conclusion the present invention children trolley it is simple in structure, when encountering barrier in children trolley traveling process without
Handle need to be pushed, it is normal to carry out front-wheel being made to clear the jumps, it is time saving and energy saving, it is very easy to use；And the children trolley
When front-wheel clears the jumps caused impact endurance test shock can also be reduced to resting on the influence of the children in children trolley.
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 can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should be covered by the protection scope of the present invention.
