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.
The embodiment 1 of stair roller devices please refers to Fig. 1 to Fig. 5, a kind of stair roller devices, comprising: transition wheel 101,
Runner 102, support frame 103, transition wheel shaft 104 and runner shaft 105, three runners surround the axis of the transition wheel
In uniform annular array, support frame as described above 103 includes that the central connecting part connecting with transition wheel and three are a pair of with each runner one
The support rod that should be connected, the transition wheel 101 are rotatablely connected by transition wheel shaft 104 and 103 central connecting part of support frame, institute
It states and is rotatablely connected in the middle part of runner 102 by runner shaft 105 and 103 support rod of support frame.
Specifically, distance is less than transition wheel 101 and runner 102 half between the transition wheel shaft 104 and runner shaft 105
The sum of diameter and transition wheel 101 and 102 diameter ratio of runner are 3:2, and 101 diameter of transition wheel is much larger than 102 diameter of runner, in this way
Design enable in stair activity, transition wheel 101 is mutually touched and is rotated with the right-angle structure of step, plays gentle transition
Effect.
103 support rod of support frame as described above is equipped with bending protruding head 106 away from one end of 103 central connecting part of support frame, described
Bending protruding head 106 overbending direction advances with the runner it is contrary, 106 end of bending protruding head equipped with protrusion runner
The protruding head monomer 107 at 102 edges, for protruding head monomer 107 in stair activity as device fulcrum, playing prevents 102 front and back of runner
The effect of rolling, while next layer of step is arrived convenient for the whole overturning again of device is lower.
Further, the bending angle of the bending protruding head 106 is 15~25 °, the bending angle of 15~25 ° of setting, neither
Can be excessive because of bending angle, it causes protruding head monomer 107 that can not contact with step in stair activity and as fulcrum, is unfavorable for filling
Whole overturning is set, will not be too small because of bending angle, cause protruding head monomer 107 to contact in advance with step, device integrally turns in advance
Turn.
Referring to Fig. 2, the protruding head monomer 107 is prong structure, by the design of 107 tip of protruding head monomer, in stair
When roller devices move in the plane, protruding head monomer 107 can be effectively prevent mutually to touch with ground, improve device in planar movement
Ride comfort.
In addition, being installed with anti-skidding rubber head 108 on the protruding head monomer 107, anti-skidding rubber head 108 can be in bending protruding head 106
When contacting with step, increase the friction of bending protruding head 106 and step, prevents bending protruding head 106 from skidding.
It please refers to referring to Fig. 5, in the present embodiment, the number of transition wheel 101 is two, and transition wheel 101 is set to described turn
The two sides of wheel 102, transition wheel 101 are set to the design of the two sides of the runner 102, are conducive to improve integrally-built stabilization
Property.
Specifically, the working principle of stair roller devices of the present invention in the present embodiment:
As shown in figure 3, stair roller devices 1 go downstairs encounter step when, during runner 102 with transition wheel shaft 104 is
Point rotates clockwise, so as on step under device runner 102, during under runner to step, and transition wheel 101 and step
Right-angle structure mutually touch and rotate, play the role of gentle transition；When runner 102 is in contact with step, protruding head 106 is bent
The protruding head monomer 107 that end is equipped with prominent 102 edge of runner is in contact with step, and protruding head monomer 107 is used as device fulcrum, plays
The effect of 102 scroll forward and backward of runner is prevented, while being to arrive next layer of platform under fulcrum unitary rotation with protruding head monomer 107 convenient for device
