Description

The Foldable multifunctional dolly

Technical field

The utility model relates to a kind of daily life car.

Background technology

Small-sized hand steered push-and-pull vehicle is of many uses, and is as public places such as home shopping, market cargo transport deliver goods or the like, indispensable.(1) in the small-sized hand steered push-and-pull vehicle that uses at present, majority is two-wheeled or four-wheel, no matter is two-wheeled or four-wheel, and each wheel while all contacts with ground.When running into the obstacle of step, ridge bank, stair one class, its resistance is big, does not say cargo transport, the unusual effort even empty wagons up/down steps or stair all seem, even can't pass through.(2) though small-sized hand steered push-and-pull vehicle volume is little, and the time spent does not take cooresponding space always, especially influence the ornaments in room, market etc. and attractive in appearance, inconvenience is simultaneously carried.

Summary of the invention

Mentioned deficiency in technical problem to be solved in the utility model above-mentioned just (1), (2), small-sized hand steered push-and-pull vehicle not only is convenient at level walking, also be convenient to up/down steps, ridge bank and stair, up/down steps, stair are as though walking upon flat ground, and this claims " multi-functional "; Car not the time spent can draw in, be easy to carry or put i.e. " collapsible ".

For this reason, the utility model adopts following technical scheme.

Six wheels that diameter is identical are arranged in its structure, each three on car both sides, three wheels become equilateral triangle to arrange.Corresponding with six wheels, six wheel stands are arranged, each three on car both sides are radial arrangement, and angle is 120 ° between adjacent two, and the one end is fixed on the outer of axletree and puts, and the other end is fixed on the wheel shaft of wheel.Therefore, each wheel can rotate (rotation) around wheel shaft separately, can rotate (revolution) around axletree again.When level walking, as four-wheeled, wheel rotates around separately wheel shaft.Run into step, under the effect of hand steered push-and-pull, wheel will roll around axletree, rolls 120 °, steps on the previous step step, rolls 120 ° again, steps on the previous step step again ...The compartment is surrounded by 4 compartment baffle plates and forms, and 4 compartment plate washers are connected with hinge with base plate respectively, can strut, and also can fold.The support leg and the base plate of car are movably connected, and the time spent struts, and the time spent does not draw in.There is a support to fold 90 ° of placements in the wheel stand on car both sides respectively to the base plate direction, when drawing dolly in, this support and wheel can be to the folding 90 ° of placements of base plate direction, when using dolly, this support can outwards strut 90 ° again, remains in the plane with corresponding two other wheel.

The Foldable multifunctional dolly that the utility model is released has tangible advantage, and the one, up/down steps and stair in push-and-pull like a cork, are convenient to shopping cargo transport, alleviate the portable hardship of bearing; The 2nd, can fold, be convenient to draw in and put and carry; The 3rd, simple in structure, make easily.

Description of drawings

Accompanying drawing 1 is the utility model structural representation.

The specific embodiment

Contrast accompanying drawing 1 is introduced embodiment of the present utility model in detail.

The utility model is fused by compartment (1), base plate (2), axletree (3), wheel (4), wheel stand (5), handrail (6), support leg (7).Compartment (1) is encircled into railway carriage or compartment shape by 4 plate washers, and every plate washer is connected with hinge (8) with base plate (2), and adjacent plate washer connects with button hook (9) or latch, and axletree (3) is fixed on the below of base plate (2).Wheel (4) is respectively six wheels that diameter is identical, each three on car both sides, and three wheels (4) become equilateral triangle to arrange.Wheel stand (5) car both sides respectively have three, are radial arrangement, become 120 ° of angles between adjacent stent.One end of wheel stand (5) is fixed on outer the putting of axletree (3), and the other end is fixed on the wheel shaft of wheel (4).A support that can fold 90 ° of placements to base plate (2) direction is arranged respectively in the car both sides wheel stands (5).Handrail (6) is movably connected in the top of the front baffle board in compartment (1).Support leg (7) is movably connected in the place ahead of base plate (2).

Have one can be to the structure of the support of the folding 90 ° of placements of base plate (2) direction in the car both sides wheel stands (5) respectively, support be divided into two sections, and two sections end connects with latch or bolt (10).
