Abstract
The invention relates to a bicycle with adjustable side wheels. The bicycle comprises a front wheel, a handlebar, a saddle, pedals and two rear wheels. The bicycle with adjustable side wheels is characterized in that the two parallel rear wheels (2) are arranged at the rear part of a bicycle body (1); a telescopic rear shaft (3) is movably arranged between the two parallel rear wheels (2); one of the two parallel rear wheels (2) can be disassembled from the bicycle body (1). Aiming at the defect of the ordinary child enlightened bicycle that the safety and stability are not good, the bicycle with the adjustable side wheels changes the traditional oriented wheel structure and directly realize the transition from the mode of four wheels or three wheels to the mode of two wheels, ensures that a child can gradually master bicycle balancing ability by adjusting the distance between the two rear wheels and quickly master the two-wheel bicycle, reduces the safety risk for the child for mastering the bicycle, and is convenient to carry.
Description
Technical field
The present invention relates to a kind of bicycle of adjustable cincture.
Background technology
Along with progress and the development of society, child has become crowd now of greatest concern, and growing up healthy and sound of child also just becomes topic the most popular at present.Study bicycle is the problem often run in the child growth stage, and present infant elementary education bicycle is mostly the structure of three directional wheels or four directional wheels, the very fast children that make can not grasp balance, and safety and stability is not strong.
Summary of the invention
The technical problem to be solved in the present invention there is provided a kind of bicycle of adjustable cincture.
Technical scheme of the present invention is: a kind of bicycle of adjustable cincture, comprise front-wheel, handlebar, vehicle seat, stretcher and trailing wheel, it is characterized in that the rear portion of bicycle body (1) is provided with trailing wheel (2) and cincture, between two parallel trailing wheels (2) and cincture, be provided with movable scalable rear axle (3); Cincture can be removed from bicycle body (1).
The bicycle of adjustable cincture of the present invention, the trailing wheel (2) parallel at two, the rear portion of bicycle body (1) is consistent with cincture diameter, and wherein trailing wheel (2) is provided with power gear device.
In order to overcome, most of infant elementary education bicycle structure is simple, safety and stability is not strong, and traditional four-wheel infant elementary education bicycle complex process, trailing wheel rub proofness is poor, unexpected removes wheel below, 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 is not very helpful to children for learning grasp two-wheeled cycle.
The bicycle of the adjustable cincture of the present invention changes traditional directional wheel structure for the defect that the safety stability of common infant elementary education bicycle is not strong and becomes the pattern of two-wheeled from four-wheel or the direct transition of three-wheel, by regulating the spacing between trailing wheel voluntarily, make child grasp balance of bicycle ability gradually, grasp the use of two-wheeled cycle as soon as possible and reduce the potential safety hazard of child in study bicycle process, be convenient for carrying.The children's safety, the balance of fast speed grasp bicycle in traveling process that have just started to learn bicycle can be enable.New infant could be imparted rudimentary knowledge to beginners bicycle and promote and enter bicycle market by this technology, in the process of children study bicycle, play very large effect, not only environmental protection but also safety, carefree enjoyment study by bike happy!
Accompanying drawing explanation
Accompanying drawing 1 is the integral structure schematic diagram of the bicycle of adjustable cincture;
In accompanying drawing: 1-is bicycle body; 2-is trailing wheel; 3-is rear axle.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment 1: the bicycle of the adjustable cincture of the present invention, comprises front-wheel, handlebar, vehicle seat, stretcher and trailing wheel, is provided with trailing wheel 2 and cincture at the rear portion of bicycle body 1, is provided with movable scalable rear axle 3 between two parallel trailing wheels 2 and cincture; Cincture can be removed from bicycle body 1.The trailing wheel 2 parallel at two, the rear portion of bicycle body 1 is consistent with cincture diameter, and wherein trailing wheel 2 is provided with power gear device.
The bicycle of the adjustable cincture of the present invention uses the distance changing trailing wheel to make bicycle be gradually transformed into general straight line state from trigonometric expression state of equilibrium, the children's fast speed under the environment of safety just having started to learn bicycle can be enable to grasp the Balancing mechanisms of bicycle in traveling process, especially efficiently solve ordinary bicycle and the very fast children that make can not 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 the distance between adjustment trailing wheel, children are adapted to gradually bicycle is transitioned into two-wheeled form by three-wheel, adopts folded form be convenient for carrying and also can extend the tenure of use of bicycle simultaneously.
Claims (2)
1. the bicycle of an adjustable cincture, comprise front-wheel, handlebar, vehicle seat, stretcher and trailing wheel, it is characterized in that the rear portion of bicycle body (1) is provided with trailing wheel (2) and cincture, between two parallel trailing wheels (2) and cincture, be provided with movable scalable rear axle (3); Cincture can be removed from bicycle body (1).
2., according to the bicycle of adjustable cincture according to claim 1, it is characterized in that the parallel trailing wheel (2) in two, the rear portion of described bicycle body (1) is consistent with cincture diameter, wherein trailing wheel (2) is provided with power gear device.
