The present embodiment can solve the problem that following problem using said structure:
First, solve equilibrium problem of the stroller when slope is stopped.Traditional stroller is that the point mode of putting forth effort is stopped, when as stopping
When being inserted into by the support bar of the strong point in soil, because the center of gravity of goods on stroller might not be just at the center of stroller
Place, therefore, when the center of gravity of goods deviates, the depth difference of support bar insertion soil can be caused, the state finally showed is to push away
Car tilts, and even turns on one's side.Therefore, the present embodiment is traditional to substitute by the way of flat clamp contacts with the face that ground is affixed
The mode that point is puted forth effort, avoids the occurrence of the situation of stroller both sides unbalance stress, in the presence of flat clamp, ensure that whole focusing surface
Stress equalization, the problem of car body will not be because of the strong point and run-off the straight, so as to significantly reduce stroller run-off the straight, side
The possibility turned over.
2nd, solve stroller to stop built on the sand, stroller is again started up the problem of laborious.Traditional stroller uses support bar conduct
Fulcrum is stopped, when stroller is loaded with weight, support bar can be trapped in soil, and in order to stop stroller on the slope, typically
Stroller is stopped by the way of directly support bar is pressed into soil, because the lower end of support bar is generally not pointed structures,
Therefore to ensure to insert must reach it is deep, it is relative will energetically, and when extracting support bar, due to having weight on slotting depth and stroller,
Need support bar could be extracted energetically again, so as to cause whole process to cause high effort for;On the other hand, due to the lower end of support bar
Be exactly a common cylinder, it is limited to the grasping force of soil, when stroller on the slope when, support bar be difficult play it is preferably solid
It is set for using, finally easily causes stroller glide automatically, be out of control, and then cause goods to tumble, even causes injury to personnel.For
This, the present embodiment has carried out the design of uniqueness, by increasing telescopic set square in insertion tube, when insertion tube is completely inserted into mud
When in soil, step on pedal and set square stretched out cylindrical portion, be inserted into soil, it is attached to grabbing for soil so as to enhance insertion tube
Power, and when needing to extract insertion tube, by unclamping pedal naturally, set square is taken in cylindrical portion in the presence of the collar
In, reduce the grasping force of insertion tube, it is easily laborsaving for the relatively conventional operation of whole process, it is easy to start stroller, and without significantly
Degree lifts handlebar, avoids the cargoes from scattering caused on stroller.
3rd, solves stroller in discharging, the problem of easily causing car body entirely to be tumbled.Traditional stroller is typically taken directly
The mode toppled over, raise handlebar, wagon box turns over forward, completes discharging, during this, due to raw material or building waste compared with
Weight, plus the weight of vehicle frame in itself, causes whole discharge process to cause high effort for, and because the amplitude that handlebar lifts is larger, lead
The construction raw material in wagon box or the mutation of building waste center of gravity are caused, so as to cause wagon box and whole stroller to turn on one's side, not only
