Abstract
This utility model is a kind of child's bicycle, including vehicle frame, front-wheel, trailing wheel, also includes a circular steel ring, a track, a slide block, an extension spring；The head end of track is connected to the wheel of trailing wheel in the heart, and such track can rotate together along with trailing wheel；Steel ring is connected on vehicle frame, and steel ring is positioned at the avris of trailing wheel, and when track rotates together along with trailing wheel, the tail end of track slides the inner side at steel ring；Slide block is slidably connected in orbit；Extension spring one end connects track head end, other end connection sliding block.This utility model has the advantage that security performance is good.
Description
Technical field
This utility model relates to the manufacture neighborhood of a kind of child's bicycle.
Background technology
Child's bicycle is liked by child deeply, and child's bicycle generally comprises vehicle frame, front-wheel, trailing wheel, the child of prior art
There is the shortcoming that some are common in bicycle, specific as follows: owing to the sexual love of child sky is played, sometimes bicycle is ridden quickly, little
Child lacks again the self-control of necessity, and too fast speed can make bicycle rollover and damage child, it can be seen that, existing
The child's bicycle security performance of technology is not good enough, it is necessary to improved.
Utility model content
The technical problems to be solved in the utility model is the present situation for prior art, it is provided that a kind of child's bicycle, and this youngster
Virgin bicycle safe excellent performance.
This utility model solves the technical scheme of the problems referred to above: a kind of child's bicycle, including vehicle frame, front-wheel, trailing wheel, goes back
Including a circular steel ring, a track, a slide block, an extension spring；The head end of track is connected to the wheel of trailing wheel in the heart, such rail
Road can rotate together along with trailing wheel；Steel ring is connected on vehicle frame, and steel ring is positioned at the avris of trailing wheel, turns together along with trailing wheel when track
Time dynamic, the tail end of track slides the inner side at steel ring；Slide block is slidably connected in orbit；Extension spring one end connects track head end, separately
One end connection sliding block.Child's bicycle of the present utility model in use, trailing wheel drive orbit rotation, under the influence of centrifugal force,
Slide block moves to track tail end direction, when the pulling force that extension spring produces just offsets centrifugal force, and slide block just stop motion, if speed
Not being quickly, slide block can't touch steel ring, and along with speed is accelerated, the centrifugal force that slide block is subject to increases the most accordingly, works as speed
Near to a certain degree time, slide block can touch steel ring, produces frictional force between slide block and steel ring, and this frictional force can suppress bicycle
Further speed up, thus ensure that bicycle is in a safe condition.
Compared with prior art, this utility model is a kind of child's bicycle, including vehicle frame, front-wheel, trailing wheel, also includes a circle
Ring-type steel ring, a track, a slide block, an extension spring；The head end of track is connected to the wheel of trailing wheel in the heart, and such track can be along with
Trailing wheel rotates together；Steel ring is connected on vehicle frame, and steel ring is positioned at the avris of trailing wheel, when track rotates together along with trailing wheel, and rail
The tail end in road slides the inner side at steel ring；Slide block is slidably connected in orbit；Extension spring one end connects track head end, and the other end connects
Slide block.This utility model has the advantage that security performance is good.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of this utility model embodiment 1.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail:
Embodiment 1
A kind of child's bicycle, including vehicle frame 1, front-wheel 2, trailing wheel 3, also includes a circular steel ring 4, a track 5,
One slide block 6, an extension spring 7；The head end of track 5 is connected on the core wheel 31 of trailing wheel 3, and such track 5 can be along with trailing wheel 3 one
Rise and rotate；Steel ring 4 is connected on vehicle frame 1, and steel ring 4 is positioned at the avris of trailing wheel 3, rotates together along with trailing wheel 3 when track 5
Time, the tail end of track 5 slides the inner side at steel ring 4；Slide block 6 is slidably connected on the rail 5；Extension spring 7 one end connects track
5 head ends, other end connection sliding block 6.
This utility model is achieved in that child's bicycle of the present utility model in use, and trailing wheel 3 drives track 5 to rotate,
Under the influence of centrifugal force, slide block 6 moves to track 5 tail end direction, when the pulling force that extension spring 7 produces just offsets centrifugal force,
Slide block 6 just stop motion, if speed is not quickly, slide block 6 can't touch steel ring 4, and along with speed is accelerated, slide block 6 is subject to
To centrifugal force increase the most accordingly, when speed is near to a certain degree time, slide block 6 can touch steel ring 4, slide block 6 and steel ring 4
Between produce frictional force, this frictional force can suppress bicycle to further speed up, thus ensure that bicycle is in a safe condition.
Although this utility model is by being described with reference to preferred embodiment, but, those skilled in the art should
Solve, in the range of claims, the various changes in form and details can be made.
