Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is more specifically described in detail.
As it is shown in figure 1, a kind of collapsible stair climbing dolly, including foldable body 1, it is symmetricly set on
The collapsible cross wheel 3 of described foldable body 1 left and right sides, it is arranged on described foldable body 1 both sides
Collapsible cross wheel 3, the support board 4 that is movably arranged on described foldable body 1, described rolls over
Folded car body 1 includes being symmetricly set on the truss structure 12 of both sides, being respectively arranged on described truss structure 12
Handle 11 and the folding link 13 (see Fig. 2) that is connected between two truss structures 12；Two
Also being arranged with slide rail 2 on truss structure 12 in parallel, side hinges is passed through in the side of described support board 4
Mechanism, to connection, can be retracted to concordant with car face of leaning to one side when making support board fold, described support board 4
Bottom is provided with the steamboat being slidably matched with described slide rail, it is achieved support board movement on dolly, slide rail
And handle, between handle with car body, securing member carries out tightening and coordinates；Described collapsible cross wheel 3 includes wheel hub
33, four can be spliced into circular configuration be embedded with rubber wheel crank arm 31, Foldable steady support 32, institute
Stating wheel hub 33 to be combined by inner ring and a radial cross bracket of equidistant bias, four are embedded with rubber
Rubber tire crank arm 31 one end four spoke free ends with cross bracket respectively be movably hinged, described can
Fold center rest 32 be connected in be embedded with rubber wheel crank arm between 31 and cross bracket, described
What Foldable steady support 32 made to be embedded with rubber wheel when stretching cranks arm 31 toward external rotation, is embedded with rubber during folding
Cranking arm of rubber tire 31 inwardly rotates, four crank arm 31 formation one and wheel hubs 33 being embedded with rubber wheel interior
Enclose concentric circle, the most described collapsible cross wheel be embedded with rubber wheel crank arm 31 after folding become circle wheel
Structure, can realize level land traveling function (see Fig. 3)；Become cross after expansion to crank arm wheel construction, building can be realized
Ladder climbing function (see Fig. 4).
Wheel hub 33 center of described collapsible cross wheel 3 is provided with unilateral bearing, utilizes unilateral bearing unidirectional
The characteristic rotated, it is to avoid period dolly falls back and brings the risk of the personnel of injuring upstairs.
As shown in Figure 2, described folding link 13 is the network structure that two sections of folding rods are constituted, can be fast
Speed folds, and can realize again the excellent support to support board 4.
The truss structure 2 of described foldable body 1 is provided with pin position assurance at extreme position and exists
The mechanical limit structure that extreme position car body is stable.
Described truss structure 12, support board 4, wheel hub 33, be embedded with rubber wheel crank arm 31, collapsible surely
Fixed rack 32 is aluminum alloy materials, has and alleviates deadweight and superpower rigidity and the weight capacity of excellence.
When the collapsible cross wheel 3 of collapsible dolly is advanced on level land, four be embedded with rubber wheel crank arm 31
It is folded up, flat-folded forms circle to contract；When to advance on ladder bank, would be embedded with rubber wheel
The Foldable steady support 32 cranked arm on 31 launch, be embedded with cranking arm of rubber wheel and 31 flex outward, with
Time, Foldable steady support 32 stretches, and cranks arm 31 effects playing support to being respectively embedded with rubber wheel,
It is made to keep deployed condition.When dolly does not uses, can by folding bicycle 1 left and right sides folding shrinking,
Reduce and take up an area space, staff can be facilitated to carry (see Fig. 5).
Above-described embodiment is this utility model preferably embodiment, but embodiment of the present utility model is not
Being limited by the examples, any of other is made without departing from spirit of the present utility model and principle are lower
