Abstract
The utility model provides a barrier surmounting vehicle of a multi-wheel changeover type, which solves the problem that a vehicle in running is difficult to surmount barricades or steps and the barrier surmounting vehicle adopts a structure that a plurality of sub wheels 1 are distributed on the same circumference in equal division mode to form the whole wheel. Each sub wheel can be rotated in turn under the action of thrust force when the wheel forwards moves, so the vehicle surmounts the barricades or the steps to realize the purpose of surmounting the barriers or surmounting the steps. The utility model can be widely used for various hand buggies or carts, and make the vehicle freely run regardless of any barriers.
Description
The utility model belongs to vehicle, particularly a kind of barrier-exceeding vehicle of hand propelled.
Traditional vehicle all is a circular wheel, and this circular wheel is advanced easily, but when running into roadblock or stepped appearance road, is difficult to advance.
The purpose of this utility model provides a kind of barrier-exceeding vehicle that can cross roadblock or stepped appearance road easily.
Technical solution of the present utility model: a kind of many wheel conversion barrier-exceeding vehicles, comprise railway carriage 5, handle 6, railway carriage 5 both sides are connected with wheel by main shaft 4, it is characterized in that wheel is made up of four the son wheel 1 of being no less than that is on the same circumference, a plurality of son wheels 1 five equilibrium on same circumference is arranged, link to each other with main shaft 4 by son wheel arm 3, son wheel 1 is to flexibly connect by sub-wheel shaft 2 with being connected of son wheel arm 3; The quantity of son wheel 1 is four; The quantity of son wheel 1 also can be five; Top corresponding to main shaft 4 on 5 liang of side box bodies of railway carriage is provided with turning Xiao 7.
The utility model adopts a plurality of son wheels that five equilibrium is arranged on the same circumference to constitute wheel, it is unaffected not only to advance on the level land, when running into roadblock, the son wheel that is obstructed has become the fulcrum of power, be right after son wheel upwards upset under thrust thereafter, thereby can cross roadblock successively, save time, laborsaving, the suitable popularization.
Further specify the utility model below in conjunction with drawings and Examples.
Fig. 1 is the utility model overall schematic.
Fig. 2 is the utility model car bottom structure scheme drawing.
Fig. 3 is the utility model running state scheme drawing.
Fig. 4 is the utility model five wheel construction scheme drawings.
As shown in Figure 1, 2, whole car is made up of railway carriage 5, handle 6, wheel and main shaft 4, wheel is positioned at railway carriage 5 both sides, is connected on the main shaft 4, and wheel is made up of four son wheels 1, four son wheels 1 are positioned on the same circumference, and five equilibrium is arranged, and son wheel 1 flexibly connects by sub-wheel shaft 2 with son wheel arm 3, and a few height wheels 1 all are connected on the main shaft 4 by corresponding son wheel arm 3, son wheel arm 3 is promptly played a supporting role, and plays the effect of the arm of force again.As shown in Figure 3, when wheel runs into ladder, son wheel A is at first stopped, and stop operating, because the effect of thrust, when A wheel arm rotates forward, son wheel D built on stilts, and the axle that son wheel B, C, D lift simultaneously with son wheel A is to overturn forward in the center of circle, causes son wheel B to touch plane on another height step, along with the continuation of thrust, when son wheel B rotates forward, son wheel A scrolls up along the facade of the step that is stopped, group wheel B rotates forward when being subjected to stopping once more, promptly finishes an action of topping bar.Like this, son wheel C, son wheel D can be turned to higher step successively under thrust, the purpose that vehicle is reached top bar.On 5 liang of side box bodies of railway carriage corresponding to main shaft 4 above, be provided with turning Xiao 7, it can be pulled back with railway carriage 5 sides and become 90 °, just be stuck in 3 of two son wheel support arms, when dolly is turned, pull down turning Xiao 7, block son wheel support arm 3, thereby the liftable antithetical phrase wheel that contacts with ground makes the son wheel that contacts with ground only surplus a pair of, thereby can easily turn.
As another embodiment of the present utility model, as shown in Figure 4, it is 5 that son wheel quantity can be set, and is positioned on the same circumference and the five equilibrium arrangement, relies on son wheel support arm to link to each other with main shaft, and its operation is similar to embodiment one.
