Abstract
The utility model relates to a barrow used for a complex road surface, which comprises a barrow body and a frame and is characterized in that the barrow also comprises an axle and star combination wheels, wherein the axle is fixed at the connecting part of the barrow body and the frame; and the two ends of the axle are respectively and symmetrically connected with the centers of gravity of the star combination wheels. The utility model has the advantages that the barrow can operate stably on the smooth road surface and also can operate freely on the complex road surfaces such as the hollow road surface and walking up and down the stairs, etc. Moreover, the barrow also has the advantages of simple production process, simple structure, durability and light dead weight, etc.
Description
Technical field
The utility model relates to a kind of go-cart that is used for complex road surface, is specially adapted to work, the life area of hollow and stair activity.
Background technology
At present, the go-cart of various work, life usefulness mostly has only a pair of wheel, and it is no doubt no problem that this go-cart is carried out at slippery traffic surface, but run into road bump, and then, operation is got up can be very difficult, even can't use; Some go-cart is installed elastic shock-absorbing device additional between wheel and vehicle body, though solved the problem of jolting, run into hollow or the bigger road surface of stair relative fall, also just can't move; Subsequently, occurred as the patent No. is the technical scheme of ZL03248603.0, this patented technology public technology scheme has increased damping cylinder, built-up wheel, technical characterictics such as cardan wheel, though its technical scheme has solved the problem of jolting, but, under the situation of complex road surface, the continuous variation that only relies on built-up wheel is to adapt to complex road surface, this is just very high to the requirement of built-up wheel, and as described in above-mentioned utility model, its built-up wheel has installed a plurality of pairs of cardan wheel bearing sleeves additional, this just influences its service life greatly, as road bump, the cardan wheel bearing sleeve very easily comes off in addition, and influence is used.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of go-cart that is used for complex road surface, and, the utlity model has in complex road surfaces such as potted road surface, stair activity operation advantage freely, and, benefits such as the utility model also has production technology, simple in structure, and durable in use, deadweight is light and handy.
For reaching above-mentioned technique effect, the technical solution of the utility model is:
A kind of go-cart that is used for complex road surface comprises vehicle body, vehicle frame, it is characterized in that also comprising axle and star pattern wheel, and described axle is fixed on the junction of vehicle body and vehicle frame, the symmetrical respectively center of gravity that connects the star pattern wheel in the two ends of axle.
The center-of-gravity position of described star pattern wheel is provided with bearing, and bearing fixing is on axle.
Described star pattern wheel comprises three wheels at least, connects by connecting panel or connecting strap between each wheel, becomes plane regular triangle between the center of circle of each wheel.
Because the utility model is symmetrically set with the star pattern wheel, under the slippery traffic surface situation, just carry out with normally go-cart is the same, as hollow or stair and complex road surface, go-cart is sunk, at this moment, the star pattern wheel has just played a role, this be because, when go-cart is sunk, though nethermost wheel can't be carried out, but its next-door neighbour's wheel still can contact with the road surface, pushes away or post-tensioning before needing only, utilize the rotation of star pattern wheel and next-door neighbour's wheel, go-cart equally can normally move.
