Set is parallel with the respective holder plate on Y type bracket, and limit rack gear is meshed with the second gear；Guide block spring is uncompressed, limit
There is position rack gear one end of fillet to be not inserted on ring set in the gap of two neighboring limit plate.
When needing to brake during carrier is mobile in flat road surface, user can push handle, and then handle
Hand channel L-type sweep, supporting block and support shaft band active toothed disk rotate clockwise；Since Y type bracket is nested in support shaft, then Y
Type bracket will not rotate.When fluted disc rotates clockwise, under the action of the first one-way clutch ring, fluted disc drives first gear inverse
Hour hands rotation；First gear drives second gear to rotate counterclockwise through telescopic rod housing and flexible interior bar, and second gear drives limit
Position rack gear is mobile to the direction of ring set, and guide block follows spaced motion, and guide block spring is compressed；Limit one end that rack gear has fillet
It is inserted into the gap between two limit plates adjacent on ring set, limits the limit plate rotation on rack gear limitation ring cuff moving ring sleeve
Turn, ultimately limit the rotation of ring set, shaft and Planetary wheel, has achieved the effect that brake to Planetary wheel.
When carrier stair climbing, the Planetary wheel positioned at carrier front end is suitable after apart from stairway step,
The suitable distance is set as S；User pushes handle, and then hand channel L-type sweep, supporting block and support shaft band active toothed disk is suitable
Hour hands rotation, then Planetary wheel brakes in flat road surface just as above-mentioned, the rotation of Planetary wheel is limited, also
It is that Planetary wheel, shaft, the second one-way clutch ring and Y type bracket constitute an interim entirety.Then, user, which continues to press on, removes
Transport vehicle, due to Planetary wheel can not rotation, and Planetary wheel external force promotion under will not occur grind landing ground sliding the phenomenon that,
So be made of Planetary wheel, shaft, the second one-way clutch ring and Y type bracket one it is interim whole will around carrier most before
The axis of shaft locating for the Planetary wheel at end rotates, and then the structure installed on Y type bracket and Y type bracket starts to roll forward
It is dynamic；The corresponding Planetary wheel of Y type bracket can stairs step, and the Planetary wheel fall in the contact point on stairway step with it is upper
The distance of the vertical plane of another step of face is equal to S；So and then by Planetary wheel, shaft, the second one-way clutch ring and Y type
The interim entirety of bracket composition one continues to roll, another corresponding Planetary wheel will be climbed above on Y type bracket
Stairway step.Three Planetary wheels in this way on Y type bracket can successively stair climbing alternately upwards, three on Y type bracket
One gear will revolve counterclockwise around the periphery of fluted disc.At this time due to the non-rotation of fluted disc, then surrounding tooth in first gear
When the periphery of disk revolves counterclockwise, first gear will generate rotation counterclockwise；First gear is through telescopic rod housing and stretches
Contracting interior bar drives second gear to rotate counterclockwise, and second gear continues to drive limit rack gear mobile to the direction of ring set, guide block with
With spaced motion, guide block spring is compressed；It is adjacent on ring set that there is limit rack gear one end of fillet more to penetrate deeply into
Gap between two limit plates limits the limit plate rotation on rack gear preferably limitation ring cuff moving ring sleeve, final limit completely
The rotation for having made ring set, shaft and Planetary wheel has achieved the effect that brake to Planetary wheel completely.Planetary wheel is stopped completely
The design of vehicle prevents from the slipping phenomenon of carrier Planetary wheel in stair climbing, avoids traditional star wheel type carrier and exists
It is easy to appear dislocation when stair climbing to skid, so that the dangerous situation of car slipping occurs in carrier, to improve carrier of the present invention
Safety when stair climbing.
During carrier of the invention continues stair climbing, the axis that Y type bracket persistently surrounds support shaft is counterclockwise
It rotates, the first gear on Y type bracket is in constantly rotation counterclockwise, and second gear is also in constantly rotation counterclockwise, in turn
Second gear can drive limit rack gear to be moved to extreme position to ring set direction；Guide block amount of spring compression reaches maximum at this time,
There is limit rack gear the distance of periphery of the one end of fillet apart from ring set to reach minimum.
In carrier stair climbing, relatively, Y type bracket is rotated around the axis of support shaft, the fixation on Y type bracket
The flexible inner panel of bar, guide tube, stripe shape expansion plate housing, the first stripe shape, the flexible inner panel of the second stripe shape, slider disc, support plate and support
Ring is followed by Y type bracket synchronous rotary；The rotation of slider disc at this time not will drive terminal pad rotation, and terminal pad and connecting column are quiet
It is only motionless.
The width of the height of stairway step vertical plane and stairway step horizontal plane in the stair that carrier of the invention is climbed
Degree needs rationally, so that three Planetary wheels on Y type bracket are in stair climbing, three Planetary wheels and respective step face contact
Position is consistent.
When needing to release the rotation limitation to Planetary wheel, user holds rim brake, and the wirerope in spool is pulled,
Wirerope pulls terminal pad mobile to the direction far from disk spring through connecting column, and terminal pad drives slider disc to separate disk spring
Direction is mobile, and disk spring is stretched.When mobile to the direction far from disk spring when slider disc, the flexible inner panel of the first stripe shape and sliding
One end that disk is connected follows slider disc mobile, and stripe shape expansion plate housing surrounds the center spot wobble of the first U-shaped board, the second stripe shape
One end that flexible inner panel is connected with the second U-shaped board is moved to the direction of telescopic rod housing, and the second U-shaped board and flexible interior bar are to stretching
The direction of contracting bar housing is mobile, and then the second gear in flexible interior bar is detached from the meshing relation with limit rack gear.When the second tooth
Wheel is detached from after limit the engaging of rack gear, and under the reset response of guide block spring, guide block drives limit rack gear to separate ring set
Direction is mobile, until guide block spring is restored to un-compressed state；To limit the one end of rack gear with fillet from adjacent two
It is detached from gap between a limit plate, has achieved the purpose that release Planetary wheel is rotated by limitation.After the completion of releasing limit, make
User unclamps rim brake, and the wirerope in spool is no longer pulled, then slider disc drives connection under the reset response of disk spring
Disk and connecting column movement reset to home position.After slider disc is mobile resets to home position, slider disc makes stripe shape again
Expansion plate housing is parallel with the respective holder plate on Y type bracket, and in the process, the second stripe shape stretches inner panel and second U-shaped
One end that plate is connected drives the second U-shaped board and the mutually direction movement far from telescopic rod housing of flexible interior bar, interior bar of finally stretching
On second gear again with limit rack gear be meshed.
Traditional carrier persistently brakes to need to hold rim brake for a long time and just be able to achieve, and carrier of the invention is only sharp
The rotation of limitation Planetary wheel can be realized automatically by being revolved just with fluted disc rotation or first gear around fluted disc periphery, to keep away
Having exempted from user persistently holds rim brake to bother brought by the rotation of restrictions planetary gear；In addition, the rotation of Planetary wheel limits
The releasing of system, it is thus only necessary to hold rim brake and just be able to achieve, considerably increase the convenience of user's operation.
Relative to traditional carrier technology, carrier of the invention in stair climbing using the rotation of Y type bracket so that
First gear on Y type bracket revolves around fluted disc periphery, and such first gear just can be in the unidirectional of the first one-way clutch ring
Second gear is driven to rotate counterclockwise through telescopic rod under effect, and then second gear drives limit rack gear more to penetrate deeply into
On ring set in the gap of two neighboring limit plate, and then the rotation of Planetary wheel, shaft and ring set is completely restricted, and avoids planet
Wheel causes the dangerous phenomenon of carrier car slipping since Planetary wheel skids in stair climbing.In addition, stripe shape expansion plate housing,
