Description

Tricycle with a steer

The utility model relates to a kind of child's bicycle, also can be used as the tricycle of riding instead of walk.

Existing child's tricycle is a front-wheel two trailing wheels, utilizes handrail turning to, and function singleness can not loading, can not modification.Children have imitation adult's psychology, like driveing a car, and wheel steering is followed adult work, and the loading transportation for example utilizes tipping bucket to transport the toy etc. of required article of the head of a family or children's play, needs a kind of suitable children's multi-function baby stroller.In addition, old the old goes out, and it is dangerous to ride two-wheeled cycle, also needs a kind of car of riding instead of walk.

The utility model purpose provides the steering wheel type underloading tricycle of a kind of children, old man's use.

Described bicycle is one type that forms after modification on the basis of existing bicycle.Vehicle body quadrangle vehicle frame, anterior " Jiong " shape wheel carrier that connects is formed a trailing wheel, two front-wheels; Front-wheel steering adopts bearing circle and drag link mechanism, and foot-driven lever and push rod, braking rear-wheel outer rim are adopted in brake; Wheel carrier supports a casing, and the upper end is fixed by the hook of vertical front frame pipe.Casing has multiple modification, and the vehicle frame lower transverse tubule can adapt to its connection that changes the outfit after extending.

The utility model satisfies interest and the requirement of children to toy car, can inspire children's intelligence, the exercise health, take part in the work, manoeuvring safety is flexible, also can be used as old man, women the car of riding instead of walk, sell the thing car.

Accompanying drawings is as follows: on a parallelogram vehicle frame 11, equipped existing cycle wheel, sprocket wheel, pedal, clothes hanger, seat cushion etc., the preceding lower end of vehicle frame connects the mid point of " Jiong " shape wheel carrier 6, respectively adorn a trident shaft 8 in the standpipe of wheel carrier two ends, respectively adorn a front-wheel 7 on the transverse horizontal axis of trident shaft, the 3rd rod end of trident shaft connects steering track rod 9, pull bar is connected with direction lever 2 lower ends through turning to driving lever 10, and direction lever is contained in the preceding standpipe 3 of vehicle frame 11, and the upper end is connected with bearing circle 1, the bearing circle rotation, direction lever is the same angle of phase inversion thereupon, and forces the driving lever swing, and two pull bars 9 move thereupon, and trident shaft is rotated, thereby two front-wheels are rotated in the same way; A casing 5 that can rotate around its fulcrum is housed on " Jiong " shape wheel carrier, and the casing upper end is fixed by hook 4 hooks, and the pivot before the hook on the standpipe 3 is that rotate in the center of circle, and is subjected to spring 16 tensionings; Brake lever 14 is a fulcrum with the pivot on the lower transverse tubule of vehicle frame 11, and can be around spot wobble, and brake lever forces push rod 12 forward and backward moving again, thus make the brake rubber block 13 that is connected in its front end and trailing wheel from, close, the trailing wheel stop rotated or discharge.

" Jiong " shape wheel carrier 6 can be connected the front end of the lower transverse tubule extension of vehicle frame 11, turns to driving lever 10 to be connected with the trident shaft 8 that is contained in " Jiong " shape wheel carrier mid point through extending pull bar 15, and the 3rd rod end of trident shaft connects two pull bars 9.

After the vehicle frame lower transverse tubule extended, there was a level interval front-wheel axial line and direction lever 2 lower ends, and casing 5 is replaceable be vehicle head 20, ring life barrels 17, general merchandise case 18 and post case 19 etc.
