Abstract
The invention discloses a kind of multiduty Maternal-infant wheel barrow operating mechanism and mother and baby's bicycles, the multiduty Maternal-infant wheel barrow operating mechanism includes: vehicle frame, on the two sides of vehicle frame rear fork or in the increased universal auxiliary wheel mechanism in the two sides position of rear axle bracket cup, increase bolt or quick lock mechanism between vehicle frame head pipe and front fork, on vehicle frame install one can front and back rotate support frame, the bracket is used to support bassinet basket or children's seat, and the vertical tube on vehicle frame can fold.The invention has the advantages that structure is simple; the fluency that mother and baby's bicycle is carried out after converting stroller can be obviously improved; and baby baby does not need individually to remove from bicycle during bicycle to be converted into the four-wheel perambulator of implementation from riding condition; always in the safety belt protection by bassinet basket; so can be safer, in addition the operation of this process is also more convenient.
Description
Technical field
The present invention relates to a kind of multiduty Maternal-infant wheel barrow operating mechanism and mother and baby's bicycles.
Background technique
Mother and baby's bicycle generally comprises front vehicle body, aftercarriage and is connected in car owner's crossbeam therebetween, wherein front vehicle body is by two
A front-wheel and its two handlebars respectively connected, vertical tube, head tube, the crossbeam of two head tubes of front fork and connection and both ends difference
The fore-stock for being connected to handlebar on the crossbeam or girder is constituted, and fore-stock is equipped with children's seat, and aftercarriage includes transmission
Device, vehicle seat, rear wheel support and rear-wheel, handlebar, which corresponds to, is connected with safety rail, children's seat on the position in front of children's seat
It is equipped with safety tread thereunder.
Current mother and baby's bicycle is usually to overturn rear-wheel to front centered on crossbeam, without auxiliary wheel, directly
Or carried out using rear wheel.The shortcomings that this mode, is: since rear-wheel cannot swing, causing rear-wheel along horizontal
Overturning is to behind front centered on beam, and when being carried out using rear wheel, more convenient but while turning round of keeping straight on has some setbacks very much.In addition,
The prior art, which also has to increase on rear-wheel, fills a universal auxiliary wheel above a shelf, become three-wheel after the overturning of bicycle 180 degree
Perambulator is still also to continue with the rear-wheel of bicycle after 180 degree overturning and carries out, because bicycle rear-wheel is unable to left and right directions and turns
It moves, so straight trip implementation is out of question after 180 degree overturning, but steering of turning round is just very laborious, and rear-wheel is being overturn forward
First baby's basket is lifted down before 180 from car and be placed on side, then could operated and rear-wheel is overturn into 180 degree, this
Process can allow the of short duration sight and distance for leaving adult of baby baby, can be dangerous, and in addition operating process is also very laborious, user
It experiences very poor.
Summary of the invention
In view of this, the main purpose of the present invention is to provide a kind of multiduty Maternal-infant wheel barrow operating mechanism, structure letter
It is single, it is easy to operate.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows: a kind of multiduty Maternal-infant wheel barrow operates machine
Structure, comprising: vehicle frame, it is characterised in that: the vehicle frame includes frame-front fork, head tube, the beam pipe between two front-wheels, girder
Pipe and rear fork, are equipped with universal auxiliary wheel component on the vehicle frame, and for rotation before and after horizontal direction or can be with
The support frame directly moved forward and backward；Bolt external member or fast lock machine are respectively set on the vehicle frame head pipe and front fork
Structure.
The present invention has substantive distinguishing features and significant progress following prominent compared with the existing technology:
First, structure is simple, increase on mother and baby's bicycle auxiliary wheel mechanism and two front wheels fixed-direction mechanism and
The support frame of bassinet basket or children's seat can will be supported along rotating mechanism before and after horizontal direction, to reach baby
Perhaps children's seat can be moved forward and backward the effect of position firstly, bassinet basket or children's seat above mother and baby's bicycle to basket
It can be rotated with horizontal direction and be moved forward and backward position, bassinet basket or children's seat are in the front of headstock, conversion under riding condition
When stroller state, bassinet basket or children's seat can be moved to the rear of headstock, increased in the near rear wheels of bicycle
Add universal auxiliary wheel, Additional wheel rotation downward perpendicular to the ground when height be higher than the rear-wheel of bicycle, when the auxiliary wheel is to backspin
When turning to land to lift bicycle rear-wheel, so that it may and two front wheels are formed together three-wheel or the baby of four-wheel pushes away
Vehicle, finally, it is parallel forward to lock two front-wheels using the bolt or quick lock mechanism installed on vehicle frame head pipe and front fork
Direction thus may be implemented to keep straight on after mother and baby's bicycle changes stroller state into from riding condition dress, turn round all
The function of easily carrying out.
Second, it is easy to operate, it is installed above the crossbeam center of two front-wheels or vehicle frame main beam or welding one
Device can allow bassinet basket or children's seat to rotate as center along horizontal direction front and back and be adjusted to specified
Bassinet basket is in front of the beam pipe between two front wheels when position, i.e. riding condition, and when handing over body stroller, bassinet basket is adjusted to
In addition beam pipe rear between two front wheels increases universal auxiliary wheel in the near rear wheels of bicycle, universal auxiliary wheel component is
It each side welds in rear axle two sides or close to the vehicle frame rear fork of rear shaft position or mounting plate or bar, then at this
Welding or install above plate or bar, there is the Additional wheel of universal turning function to form, and Additional wheel is in addition to can be horizontal
All around except universal rotational, the casing or socket for connecting auxiliary wheel can be rotated with vertical direction to be adjusted the angle in direction,
When perpendicular to the ground the height of auxiliary wheel be higher than bicycle rear-wheel, under riding condition baby seat or basket along two
It is auxiliary at left and right sides of rear-wheel being mounted on after the center of crossbeam between a front-wheel rotates 180 degree for center horizontal direction
Helping wheel to adjust downwards, direction first lands perpendicular to the ground and two front-wheels can be converted into pushing away for four wheel constructions together
Vehicle, then the bolt or quick lock mechanism of connection head tube and front fork are shut, after fixing the parallel direction facing forward of two front-wheels, just
The implementation can flexibly turn to very much, kept straight on.
