Description

Multi-function portable hand cart

The utility model belongs to transportation means.

The present portable trailer of the normally used manned fortune thing of people, though vehicle body and backrest can fold, wheel generally can not folding, it is still bigger to take up space, and carries inconvenience, does not especially satisfy by stair weight is transported to upstairs requirement with trailer.

The purpose of this utility model provides a kind of portable multifunctional trailer, and is easy to carry to satisfy as a kind of transportation means, the requirement of loading stair climbing.

The utility model is achieved in that front vehicle wheel passes through front-wheel pole, and rear wheel makes the wheel folding by lower supporting arm of rear wheel, and front vehicle wheel is made up of three rollers of interval 120 degree, to satisfy the requirement of stair climbing.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is an assembled state lateral plan of the present utility model.

Fig. 2 is an assembled state back view of the present utility model.

(1) is handrail among the figure, and (2) are front-wheel pole, and (3) are framework, (4) be roller, (5) be rolling wheel support, (6) are backrest, and (7) are pull bar, (8) be carriage, (9) be upper supporting arm of rear wheel, (10) are bayonet lock, and (11) are lower supporting arm of rear wheel, (12) be rear wheel fork, (13) are brace.

Main points of the present utility model are that front vehicle wheel is two fulcrums, and rolling wheel support (5) and three rollers (4) of being spent by interval 120 form. Bayonet lock (10) is provided with boss, by rotation, backrest (6) can move forward, the fulcrum of front-wheel pole (2) on framework (3) rotates, front-wheel is packed up, upper supporting arm of rear wheel (9) is because linking to each other with backrest (6) bottom, so the fulcrum of rear wheel on lower supporting arm of rear wheel (11) and framework (3) rotates, trailing wheel is packed up. When it was folding, handrail (1) and backrest (6) moved forward, and made carriage (8) vertical with framework (3) by pull bar (7). Rear wheel is single fulcrum, can Free by the bearing on the rear wheel fork (12), and by being provided with tie point between upper supporting arm of rear wheel (9) and the lower supporting arm of rear wheel (11), rear wheel can fold with front vehicle wheel and become an inclined-plane, to satisfy the needs of stair climbing. When up drawing trailer by stair, rear wheel is in half and receives overlapping state, relies on front vehicle wheel to rotate around the pivot pin on rolling wheel support (5) and the front-wheel pole (2), finishes manned fortune thing upstairs. When front and back wheel was put down, backrest (6) blocked with bayonet lock (10) and props, and just forms a go-cart or seat, can be on the level land manned fortune thing, taking in the time of also can doing tourism has a rest uses.

After backrest (6) was folding, the trailing wheel stowed position was higher than front-wheel, only has front wheel landing, and whole support body dwindles, and at this moment pull bar (7) draws carriage (8), made carriage (8) and framework (3) vertically upward, was convenient to consign weight upstairs or the level land transportation. As pull bar (7) folding is moving, carriage (8) can be set level forward, and it is very little to take up space with the pallet of two-wheeled namely to become one, easy to carry.

The gear bowl formula bearing that bearing all adopts bicycle to use, light and flexible, cheap. Roller (4) adopts plastic wheel hub, and rubber wheel band is light steady, noiselessness. Bayonet lock (10) adopts and revolves the pin formula, namely is welded with boss at sleeve pipe, namely blocks backrest (6) when the bayonet lock boss forwards the top to, and below the bayonet lock boss forwarded to, backrest (6) is namely collapsible, and was very convenient.
