Abstract
The utility model relates to a good carrying and climbing trolley by lever principle, which comprises a basket (1), a handle (2), a large wheel assembly (3) and another large wheel assembly (4), a frame body (5), a small wheel assembly (6) and another small wheel assembly (7). The included angle between the large and small wheel assemblies is 90 degrees. When the trolley travels on the ground, the large wheels is landed and the small wheels are suspended. The trolley can cross obstacles such as grooves which are not wider than 35 cm or pipelines which are smaller than 15 cm in diameter, and can climb up and down freely when the trolley comes across steps not higher than 30 cm. The trolley is not blocked and when the trolley is needed to climb stairs, the large and small wheels are respectively used supporting points, and the handle is used as a lever, so that the trolley climbs layer by layer. The trolley is simple to operate, very light and labor saving when the trolley carries goods and climbs stairs by the lever principle, and remarkable in effect. The trolley is unique in model and simple in structure. The whole trolley is connected rigidly, free from noise pollution, robust and durable, and in particular suitable for use by residents in high-rise houses without elevators for shopping outside. The trolley is further suitable for use when goods are needed to be conveyed up stair or up step.

[specific implementation method]
Fig. 2 is a kind of exploded drawings in kind that uses the dolly that the lever principle loading climbs the building of the present utility model.With reference to Fig. 1, car frame (1) and main body of vehicle frame (5) are welded.Trundle assembly (6) and trundle assembly (7) weld with main body of vehicle frame (5).Big wheel assembly (3) is connected 4 with the big wheel assembly) be connected with main body of vehicle frame (5).Respectively with fixing with bolt (19) and nut (21), bolt (24) and nut (23) behind bolt hole (17) and bolt hole (20), bolt hole (22) and bolt hole (25) aligned position.After anti-slip rubber sleeve pipe (9) packaged on the handlebar (2), handlebar (2) was connected with main body of vehicle frame (5).Respectively with fixing with bolt (8) and nut (12), bolt (16) and nut (13) behind bolt hole (11) and bolt hole (14), bolt hole (15) and bolt hole (18) aligned position.Pipe link (10) and handlebar (2) are welded.Size wheel set, bolt nut are commercial.Other is made for shape.
Fig. 3, Fig. 4, Fig. 5 are that a kind of dolly that uses the lever principle loading to climb the building of the present utility model is climbed building action and lever principle schematic diagram.1, big wheel is propped up the vertical surface of ground floor stair; The dolly wheel carrier is at the front end (seeing Fig. 3) of second layer stair horizontal surface.2, make progress, exert oneself forward, at power F and F as propping up the handlebar of naming a person for a particular job take trundle
1Effect under big wheel scroll up along the vertical surface of ground floor stair, climb up the horizontal surface (seeing Fig. 4) of ground floor stair.Because the stress point on the handlebar arrives the length L 2 (resistance arm) of fulcrum much larger than the center of gravity of goods position to the length L 1 (power arm) of fulcrum, therefore use lever principle, loads the dolly of weight and can climb up easily one deck stair.3, take big wheel as fulcrum, handlebar is exerted oneself forward downwards, at power F
2And F
1Effect is lower, and trundle scrolls up along the vertical surface of the 3rd floor ladder, climbs up the horizontal surface (seeing Fig. 4) of the 3rd floor ladder.Since the stress point on the handlebar to the length L 3 (power arm) of fulcrum much larger than the center of gravity of goods position to the length L 4 (resistance arm) of fulcrum owing to lever principle, its labor-saving effect is same as described above.Dolly repeats initial actuating afterwards, the next circulation of beginning (seeing Fig. 5).

1Effect under, big wheel scrolls up along the step vertical surface, climb steps horizontal surface (seeing Fig. 7).3, take big wheel as fulcrum, handlebar is downwards forward firmly at power F
2And F
1Effect is lower, dolly move ahead (seeing Fig. 8).
Fig. 9, Figure 10, Figure 11 are a kind of dolly that uses the lever principle loading to climb the building of the present utility model schematic diagrams of getting out of a predicament or an embarrassing situation.1, take big wheel as fulcrum, handlebar is (seeing Fig. 9) upwards firmly.Trundle lands under the effect of power F.2, take trundle as fulcrum, handlebar upwards exert oneself backward (seeing Figure 10) is at power F and F
3Effect under, big wheel falls step and lands, and finishes the action (seeing Figure 11) of getting out of a predicament or an embarrassing situation.
Figure 12, Figure 13, Figure 14 are that a kind of dolly that uses the lever principle loading to climb the building of the present utility model is crossed over groove action schematic diagram.1, take trundle as fulcrum, handlebar upwards exert oneself forward (seeing Figure 12).2, at power F and F
1Effect under, dolly is crossed over groove (seeing Figure 13).3, take big wheel as fulcrum, handlebar is exerted oneself downwards forward, at power F
2And F
1Effect under trundle move ahead (the seeing Figure 14) that come back.The action of the obstacles such as crossing pipeline is same as described above.
Above-described embodiment is not the unique embodiment of a kind of dolly that uses the lever principle loading to climb the building of the present utility model, all conversion of on above-described embodiment basis, doing or replacement, and the embodiment of generation is all within rights protection scope of the present utility model.
