Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to attached drawing 1 and attached drawing 2, the embodiment of the invention discloses a kind of flexible stair climbing wheels for hanging pawl of band, comprising: wheel shaft 3,
Core wheel 1 and telescopic claw 2;
Core wheel 1 is mounted on wheel shaft 3, and running through on core wheel 1 has multiple guide holes 4;Specific guide hole 4 is linear guide hole;
Wherein, guide hole 4 is that advance reservation comes out on core wheel 1;
Referring to attached drawing 3, telescopic claw 2 includes: that rigid bracing 5, spring 6 and arc hang pawl 7;
Rigid bracing 5 passes through guide hole 4 and wheel shaft 3, and 5 two sides of rigid bracing are mounted on spring 6, rigid bracing 5
Both ends are respectively and fixedly provided with arc and hang pawl 7;
In specific implementation, rigid bracing and arc are hung pawl and can be fixed by welding, can also pass through
It is threadedly coupled, rigid bracing TBE (threaded both ends), arc hangs pawl and has internal thread nut.
The radian that arc hangs pawl 7 is identical as the outer rim radian of core wheel 1.
Telescopic claw is mounted in guide hole, realizes the sliding in guide hole by the restoring force of spring.Arc climbs the radian of pawl
It is identical as the radian of the outer most edge of core wheel, but when telescopic claw is compressed, arc climbs pawl and is close to core wheel outer rim, it is ensured that wheel
Rolling radius is constant, normal to roll.
In order to further optimize the above technical scheme, the angle between adjacent passages 4 is between 45 °~60 °.
In order to further optimize the above technical scheme, guide hole 4 radially distributes.Preferably, each guide hole 4 is radial
It is uniformly distributed.
In order to further optimize the above technical scheme, the end that arc hangs pawl 7 is provided with friction plate.
It hangs on pawl, can also be fixed by screws in specifically, friction plate can be fixed on arc by way of stickup
Arc is hung on pawl.
In the settable friction plate in the end that arc climbs pawl, increasing friction force guarantees that arc climbs the steady of pawl and step contact point
It is fixed, it prevents from skidding, realizes to stablize and cross over step.
In order to further optimize the above technical scheme, spring one end is fixed with wheel shaft, and the other end is free end, and and arc
Pawl is hung to be in contact.
In order to further optimize the above technical scheme, limiting section, spring one end and the wheel shaft are installed on rigid bracing
Fixed, the other end is free end, and is in contact with limiting section.
In order to further optimize the above technical scheme, multiple through-holes to match with rigid bracing 5 are offered on wheel shaft 3,
Rigid bracing 5 runs through through-hole.
Rigid bracing passes through the through-hole on guide hole and wheel shaft on core wheel, and guide hole is exposed at both ends, and two sides are respectively provided with
There is spring, wherein one end of spring is fixed with wheel shaft, and the other end can be free end, can also be hung pawl with arc and be fixed, may be used also
Limiting section to be arranged on rigid bracing, the other end is fixed with limiting section.Under the effect of top luggage gravity pressure, rigid bracing
One end is retracted core wheel, and the other end is ejected, and telescopic claw end is bonded with the outer rim of core wheel, does not change the rolling half of core wheel
Diameter guarantees that normal roll moves ahead, and after scrolling through this rigid bracing, under the action of the restoring force of spring, rigid bracing is multiple
Position.
In addition, trolley luggage, which includes that above-mentioned band is flexible, hangs pawl the embodiment of the invention also provides a kind of trolley luggage
Stair climbing wheel can very easily realize ladder, mitigate the burden of user.
Below with reference to specific walking principle, further details of the technical solution of the present invention.
In level road, when telescopic claw turns to when being contacted with ground, under the effect of top luggage gravity pressure, telescopic claw edge
Guide hole is retracted in core wheel, and telescopic claw end is bonded with the outer rim of core wheel, does not change the rolling radius of core wheel, is guaranteed normal
It rolls and moves ahead.
Referring to attached drawing 4, in top bar, it is being self-possessed with the telescopic claw of current step plane and upper level step contact aside
It is normally rolled with being retracted in core wheel under the action of towing tension, and the telescopic claw on top tangles upper level step during rotation,
Wheel body hangs pawl and the positive contact point of upper level step using arc and completes to roll promotion as fulcrum, to realize the function across step
Can, it is very convenient, it is effectively reduced the burden of user.
When getting out of a predicament or an embarrassing situation, it is similar with level road to roll principle, and front stretches out arc in advance and hangs pawl, due to the reply of spring
Stress effect has certain buffer function for lower jump of the luggage on step.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.For device disclosed in embodiment
For, since it is corresponded to the methods disclosed in the examples, so being described relatively simple, related place is said referring to method part
It is bright.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
