Abstract
The utility model relates to a bicycle with an adjustable rear-wheel spacing. The bicycle comprises a front wheel, a bicycle head, a seat, pedal plates and rear wheels. The bicycle is characterized in that the rear part of a bicycle body (1) is provided with the two parallel rear wheels (2), and a movable telescopic rear shaft (3) is arranged between the two parallel rear wheels (2); one of the two parallel rear wheels (2) can be removed from the bicycle body (1). The bicycle has the advantages that aiming at the defect of poor safety and stability of the enlightened bicycle of common children, the traditional directional wheel structure is changed, and is directly transitioned from a four-wheel mode or a three-wheel mode into a two-wheel mode; by adjustment of the spacing between the rear wheels, the children can master the balancing capability of the bicycle gradually, and master the use of the two-wheel bicycle, so that the potential safety hazards of the children in the process of learning the bicycle is reduced, and the carrying is convenient.
Description
Technical field
The utility model relates to a kind of bicycle of adjustable trailing wheel spacing.
Background technology
Along with social progress and development, child has become crowd of greatest concern now, and growing up healthy and sound of child also just becomes the most popular at present topic.Study bicycle is the problem often running in the child growth stage, and present infant elementary education bicycle is mostly the structure of three directional wheels or four directional wheels, can not the very fast children that make grasp balance, and safety and stability is not strong.
Summary of the invention
The technical problems to be solved in the utility model has been to provide a kind of bicycle of adjustable trailing wheel spacing.
The technical solution of the utility model is: a kind of bicycle of adjustable trailing wheel spacing, comprise front-wheel, handlebar, vehicle seat, stretcher and trailing wheel, the rear portion that it is characterized in that bicycle body (1) is provided with two parallel trailing wheels (2), is provided with movable scalable rear axle (3) between two parallel trailing wheels (2); In two parallel trailing wheels (2), there is a trailing wheel (2) to remove from bicycle body (1).
The bicycle of adjustable trailing wheel spacing of the present utility model, consistent in two the parallel trailing wheels in rear portion (2) diameter of bicycle body (1), rear axle (3) is provided with power gear device.
In order to overcome, most of infant elementary education bicycle structures are simple, safety and stability is not strong, and traditional four-wheel infant elementary education bicycle complex process, trailing wheel rub proofness is poor, the unexpected wheel by is below removed, children still can not be skilled grasp balance, meanwhile, traditional infant elementary education bicycle is also inconvenient to carry.Tradition three-wheel child bicycle structure is simple, but children for learning is grasped to two-wheeled cycle, is not very helpful.
The pattern that the bicycle of the adjustable trailing wheel spacing of the utility model has changed traditional directional wheel structure and become two-wheeled from four-wheel or the direct transition of three-wheel for the not strong defect of the safety stability of common infant elementary education bicycle, by regulating voluntarily the spacing between trailing wheel, make child grasp gradually balance of bicycle ability, grasp as soon as possible the use of two-wheeled cycle and reduced the potential safety hazard of child in study bicycle process, be convenient for carrying.The children that can make just to have started to learn bicycle can safety, fast speed is grasped the balance of bicycle in traveling process.This technology could be imparted rudimentary knowledge to beginners New infant bicycle and be promoted and to enter bicycle market, in the process of children study bicycle, plays very large effect, not only environmental protection but also safety, by bike happy of carefree enjoyment study!
Accompanying drawing explanation
Accompanying drawing 2 is structural representations of the large spacing of rear-view for bicycle of adjustable trailing wheel spacing;
Accompanying drawing 3 is the closely spaced structural representations of the rear-view for bicycle of adjustable trailing wheel spacing;
Accompanying drawing 4 is forward sight structural representations that the bicycle of adjustable trailing wheel spacing is cancelled a trailing wheel;
In accompanying drawing: 1-is bicycle body; 2-is trailing wheel; 3-is rear axle.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1: the bicycle of the adjustable trailing wheel spacing of the utility model, comprise front-wheel, handlebar, vehicle seat, stretcher and trailing wheel, at the rear portion of bicycle body 1, be provided with the scalable rear axle 3 that is provided with activity between 2, two parallel trailing wheels 2 of two parallel trailing wheels; In two parallel trailing wheels 2, there is a trailing wheel 2 to remove from bicycle body 1.At two, the rear portion of bicycle body 1, parallel trailing wheel 2 diameter are consistent, and rear axle 3 is provided with power gear device.
The bicycle of the adjustable trailing wheel spacing of the utility model uses the distance that changes trailing wheel to make bicycle be gradually transformed into general straight line state from trigonometric expression state of equilibrium, the children that can make just to have started to learn bicycle can grasp the balancing machine device of bicycle in traveling process by fast speed under the environment of safety, especially efficiently solve ordinary bicycle and can not the very fast children that make grasp balance, and the problem such as safety and stability is not strong.
The trailing wheel adapter shaft of bicycle is designed to telescopic form, front-wheel is flower wheel, by adjusting the distance between trailing wheel, make children adapt to gradually bicycle and by three-wheel, be transitioned into the form of two-wheeled, adopt folded form to be convenient for carrying and also can to extend the tenure of use of bicycle simultaneously.
Claims (1)
1. the bicycle of an adjustable trailing wheel spacing, comprise front-wheel, handlebar, vehicle seat, stretcher and trailing wheel, the rear portion that it is characterized in that bicycle body (1) is provided with two parallel trailing wheels (2), is provided with movable scalable rear axle (3) between two parallel trailing wheels (2); In two parallel trailing wheels (2), there is a trailing wheel (2) to remove from bicycle body (1); Two the parallel trailing wheels in rear portion (2) diameter of described bicycle body (1) is consistent, and rear axle (3) is provided with power gear device; Power gear device on described rear axle (3) provides power by stretcher, and rear axle (3) drives trailing wheel (2) to rotate the operation that realizes bicycle; Front-wheel is flower wheel, by adjusting the distance between trailing wheel, makes children adapt to gradually bicycle and by three-wheel, is transitioned into the form of two-wheeled.
