Above-mentioned vehicle frame is rectangle, and along laterally being fixed with the supporting-roller shaft (5,6,7) that is parallel to each other, said support roller is rotationally and is contained on the supporting-roller shaft on the vehicle frame.
The two ends of above-mentioned vehicle frame be hinged the respectively lower end of strut (8) and the lower end of slide bar (9), the dop of the upper end of strut (10) is bearing fit with the chute (11) of slide bar upper edge slide bar direction, and there is the positioning (12) of dop the chute termination.
Be connected with pull bar on the above-mentioned vehicle frame.
Said structure of the present utility model makes it have following advantage and effect.
One, traveling crawler structure of the present utility model because the ground contact area of crawler belt is big, therefore has walking pulsation-free advantage on the road of pavement roughness.In addition at the diameter of the support roller of vehicle frame front and back end less than structure at the diameter of the support roller at vehicle frame middle part, not only make it have the advantage of on the road of pavement roughness, walking, and have the advantage that makes things convenient for going up or down stairway on ladder, to walk.
Two, strut of the present utility model, slide bar, dop, positioning structure constitute the drag gear of this trailer, and when going up or down stairway or when not needing strut, dop slides to the lower end along chute, and strut and slide bar are transferred on the vehicle frame face, is the folding shape.When needing to use strut, dop slides to the upper end along chute and is bracket-like, is convenient to dilatory carrying out on the road surface.
The utility model is applicable to and the supporting use of luggage, also can make one with luggage and use, and can also be used to move weight, as refrigerator, laundry machine, large screen television, bin etc.
Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
