The present embodiment uses said structure to can solve the problem that following problem:

One, equilibrium problem when go-cart is stopped is solved on slope.Traditional go-cart is that the some mode of putting forth effort is stopped, when as stopping When being inserted in earth by the support bar of the strong point, owing in go-cart, the center of gravity of goods might not be just at the center of go-cart Place, therefore, during the deviation of this center of gravity of goods, can cause support bar to insert the degree of depth difference of earth, and the state finally presented is to push away Car tilts, and even turns on one's side.To this end, the mode that the face that the present embodiment uses flat clamp to be affixed with ground contacts is traditional to replace The mode that point is puted forth effort, it is to avoid the situation of go-cart both sides unbalance stress occurs, under the effect of flat clamp, it is ensured that whole focusing surface Stress equalization, car body will not the run-off the straight because of the problem of the strong point, thus significantly reduce go-cart run-off the straight, side The probability turned over.

Two, solving go-cart to stop built on the sand, go-cart is again started up laborious problem.Traditional go-cart uses support bar conduct Stopping fulcrum, when go-cart is loaded with weight, support bar can be trapped in earth, and in order to stop go-cart on the slope, typically The mode being directly pressed in earth by support bar is used to make go-cart stop, owing to the lower end of support bar is generally not pointed structures, Therefore to ensure to insert enough deep, relatively will the most, and when extracting support bar, owing to inserting deeply and to have weight in go-cart, Need again could be extracted by support bar energetically, thus 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, limited to the grasping force of earth, when go-cart on the slope time, support bar is difficult to play the most solid Be set for use, be finally easily caused go-cart automatically glide, out of control, and then cause goods to be tumbled, even cause 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 Time in soil, step on pedal and make set square stretch out cylindrical portion, be inserted in earth, thus enhancing insertion tube and earth is grabbed attached Power, and when insertion tube is extracted by needs, by naturally unclamping pedal, make set square take in cylindrical portion under the effect of the collar In, reduce the grasping force of insertion tube, for the relatively conventional operation of whole process, the most laborsaving, it is simple to start go-cart, and without significantly Degree lifts handlebar, it is to avoid cause the cargoes from scattering in go-cart.

Three, solution go-cart is when discharging, is easily caused the whole problem tumbled of car body.Traditional go-cart is typically taked directly The mode toppled over, raises handlebar, and wagon box turns over forward, completes discharging, during this, due to raw material or building waste relatively Weight, adds the weight of upper frame itself, causes whole discharge process to cause high effort for, and the amplitude lifted due to handlebar is relatively greatly, leads Cause the construction raw material in wagon box or the sudden change of building waste center of gravity, consequently, it is possible to cause wagon box and whole go-cart rollover, not only Affect discharging, and it is injured to also can result in operator.To this end, the application adds accessory plate and some 4th springs, auxiliary Helping plate and sweep hinged away from one end of handlebar, one end of the 4th spring is fixed on the lower section of accessory plate, and the other end is fixed on car On plate.When turning over before wagon box prepares under the effect of inertia when, accessory plate, under the effect of the 4th spring, has equally to car The movement tendency of front edge of board upset, now, can suitably reduce the height that handlebar lifts, i.e. wagon box only needs certain speed, is joining Close the active force that accessory plate gives, can turn over before easily realizing wagon box, complete discharging such that it is able to more laborsaving, due to, equally On the basis of turning over before realizing wagon box, this programme can reduce the height that handlebar lifts further, say, that compares traditional side Formula, the difference in height change of wagon box reduces further, and the gravity center shift of the object in wagon box is relatively smaller, so that whole discharging More steady, and be found by experiment that, this programme has only to 20 ~ 25 degree and can turn over before easily realizing wagon box, is not susceptible to simultaneously Rollover, safety is higher.It addition, the application also add some 5th springs, one end of the 5th spring is fixed on the end of wagon box Portion, the other end is fixing on the auxiliary board.Under the effect of the 5th spring, after wagon box completes discharging, the 5th spring and the 4th bullet Spring is in extended state, after discharging, and the weight of the most surplus wagon box, therefore, only need to somewhat put down handlebar, wagon box can be the Under the effect of four springs and the 5th spring, it is achieved returning, and, under the effect of the 4th spring and the 5th spring, it is possible to car The returning of bucket plays cushioning effect, and one can reduce the impact force between wagon box and sweep, makes operation safer, and two is permissible Reduce the noise sent between wagon box and sweep.

Four, solution go-cart is when Uneven road or center of gravity of goods shakiness, is easily caused go-cart and tumbles, and causes goods to dissipate Fall, the problem that even trammer is injured.Traditional go-cart balance in running leans on trammer, control, pushing away substantially During car, careless slightly, it is easily caused tilting of car body, along with the continuous aggravation of magnitude of inclination, ultimately resulting in go-cart can not Control and thoroughly tumble.To this end, embodiment adds tilting prevention device, this device can when sweep is tilted beyond certain angle, Realize automatically opening up of tilting prevention device, thus the car body tilted played good supporting role, slow down the slope trend of car body, It is easy to trammer have sufficient time to adjust, also avoids car body directly to tumble simultaneously, make the goods on car avoid being scattered, also keep away Trammer is caused infliction of body because action is excessive by the car body exempting to tumble, even if the strongest people of equilibrium sense promotes this little Car, same it can be avoided that occur that dolly is tumbled, therefore, effectively increase go-cart is suitable to crowd.

The above, be only preferred embodiment of the present utility model, and this utility model not does any pro forma limit System, every according to technical spirit of the present utility model, above example is made any simple modification, equivalent variations, each fall within Within protection domain of the present utility model.
