Utility model content
In order to improve the handling efficiency of coolie practitioner, ensureing the personal safety of bearer, this practicality is new
Type provides a kind of collapsible cross wheel of cranking arm.
This utility model adopts the following technical scheme that
A kind of collapsible cross wheel of cranking arm, including wheel hub, four can be spliced into circular configuration be embedded with rubber
Wheel crank arm, Foldable steady support, described wheel hub is by inner ring and a radial cross of equidistant bias
Shape holder combination forms, four one end cranked arm being embedded with rubber tyre respectively with four of cross bracket
Spoke free end is movably hinged, and described Foldable steady support is articulated with cranks arm and between cross bracket,
Make during described Foldable steady stent to crank arm toward external rotation, crank arm during folding and inwardly rotate, four songs
Arm forms a circle concentric with the inner ring of wheel hub.
Further, Foldable steady support includes the first folding connecting rod, the second folding being connected through the hinge
Folded connecting rod, is connected with hinged with the second folding connecting rod between four spokes of described cross bracket
Arc connecting portion, described first folding connecting rod, the second folding connecting rod are co-operatively provided with and ensure at song
Arm extends to keep during extreme position stable mechanical limit structure.
Further, described mechanical limit structure includes the spacer pin being arranged on described second folding connecting rod
Stopper slot on nail and described first folding connecting rod, cranks arm when extending to extreme position, described position-limitting pin
Foldable steady support is made to realize self-locking purpose at extreme position in snapping in stopper slot.
Further, described hub centre is provided with unilateral bearing, utilizes the spy of unilateral bearing one-directional rotation
Property, it is to avoid period dolly falls back and brings the risk of the personnel of injuring upstairs.
Further, described wheel hub, crank arm, Foldable steady support is aluminum alloy materials, have and subtract
Light dead-weight and superpower rigidity and the weight capacity of excellence.
The beneficial effects of the utility model:
This utility model uses collapsible structure design of cranking arm, and uses chain connection, processing between each component
Convenient, design and the hub centre cranked arm install unilateral bearing additional simultaneously, it is to avoid period dolly falls back upstairs
The emergency risk that may bring.And, be embedded with rubber tyre crank arm design not only weaken level land advance time
Vibrations, also make the motion of goods in uphill process the mildest.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is more specifically described in detail.
As shown in Figures 1 to 7, a kind of collapsible cross wheel of cranking arm, can be spliced into including wheel hub 4, four
Circular configuration be embedded with rubber wheel crank arm 1, Foldable steady support, described wheel hub 4 is by inner ring and one
Equidistant eccentric radial cross bracket combines, four be embedded with rubber tyre 5 crank arm 1 one
End four spoke 41 free ends with cross bracket respectively are movably hinged, and described Foldable steady support cuts with scissors
It is connected to crank arm between 1 and cross bracket, makes during described Foldable steady stent to crank arm 1 toward outward turning
Turning, cranking arm during folding 1 inwardly rotates, the circle that four 1 formation one of cranking arm is concentric with the inner ring of wheel hub 4.
Foldable steady support includes first folding connecting rod the 2, second folding connecting rod 3 being connected through the hinge,
The arc hinged with the second folding connecting rod 3 it is connected with between four spokes 41 of described cross bracket
Connecting portion 42, described first folding connecting rod the 2, second folding connecting rod 3 is co-operatively provided with and ensures
Crank arm 1 mechanical limit structure extending to keep during extreme position stable.
Described mechanical limit structure includes being arranged on the position-limitting pin 31 on described second folding connecting rod 3 and institute
State the stopper slot 21 on the first folding connecting rod 2, crank arm 1 when extending to extreme position, described position-limitting pin
