Abstract
The utility model relates to a bicycle speed booster, which is composed of a main frame, a rear hanger, a rear wheel, pedals, a rolling wheel, a front wheel and a transversal rod. The utility model is characterized in that the rolling wheel in a circular disk shape is installed on the triangle-shaped main frame. The utility model is the novel bicycle speed booster which has practical valve.
Description
The utility model relates to a kind of new bicycle speed enhancing apparatus.(IPC) belongs to the operation department of Transport by International Patent Classification (IPC), communications and transportation branch, the big class of trackless terrestrial vehicle, wheel or skid that rider drives, be specially adapted for the driving device group of these vehicle, to use endless chain or similar component driving device technical group field as feature.Be numbered B62M 9/00.
At present, existing and once had about to use endless chain or similar component the demand of new bicycle speed enhancing apparatus all to be done very fruitful effort as the technology of the driving device of feature, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Li Linqing, Granted publication number is CN2235405Y, China Patent No. (ZL) is: No. 95240486.9 utility model title is the utility model patent of " bicycle acceleration mechanism ", the technical scheme that is adopted.Be a routine of great value invention to use endless chain or similar component as the driving device technical elements of feature, it has solved the problem of bicycle acceleration mechanism effectively.But still have some deficits, it also be difficult to solve present ordinary bicycle and easily takes off chain, and takes off cochain difficulty behind the chain and the not high problem of speed.
The purpose of this utility model is to provide a kind of new bicycle speed enhancing apparatus.Easily take off chain to solve present ordinary bicycle, and take off cochain difficulty behind the chain, and the not high problem of speed.
The purpose of this utility model is achieved in that a kind of new bicycle speed enhancing apparatus of this utility model.Mainly by main frame, back clothes hanger, trailing wheel, pedal plate, roller, front-wheel, cross bar and constitute.Its vital parts roller, trailing wheel are round-shaped, make material with steel, through casting, ground finish manufacturing.Its front-wheel is round-shaped, makes material with rubber, through plastic cement shaping processing and manufacturing.Its round-shaped front-wheel adopts the bearing pin coupling method to be installed on the triangular shaped main frame.Form the car wheel structure of a disc-shape.The roller of its disc-shape adopts the bearing pin fixing means to be installed on the triangular shaped main frame.Form the car body drive configuration of a disc-shape.The plate of pedaling of its bent stick shape adopts the bearing pin fixing means to be installed on the roller of disc-shape.Form the roller drive configuration of a bent stick shape.The trailing wheel of its disc-shape adopts the cross bar fixing means to be installed in the flow roll wheel of disc-shape.Form a round-shaped structure of friction wheel.Its back clothes hanger acts on trailing wheel by the screw retention method, thereby makes trailing wheel satisfy the requirement of supporting the back clothes hanger.Its roller in trailing wheel, drives task that trailing wheel rotate thereby roller is finished by the friction car by rubbing effect.So just realized the purpose of this utility model.
The utility model with original to use endless chain or similar component to compare three advantages and improvement as the driving device technology of feature;
The first, because the utility model has designed roller in technical scheme, replaced chain so solved, solve the problem that bicycle easily takes off chain;
The second, because the utility model has designed the rigidity trailing wheel in technical scheme, so solved the problem of the speed that has improved trailing wheel;
The 3rd, because the utility model project organization in technical scheme is simple, so solved problem easy to process.Easily take off chain thereby just can more effectively solve present ordinary bicycle, and take off cochain difficulty behind the chain, and the not high problem of speed.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the general shape structural representation of a kind of new bicycle speed enhancing apparatus of the utility model;
The numbering of parts explanation in the scheme drawing: 1 main frame, 2 back clothes hanger 3 trailing wheels 4 are pedaled plate 5 rollers 6 front-wheels 7 cross bars
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, a kind of new bicycle speed enhancing apparatus of the utility model.Mainly by main frame 1, back clothes hanger 2, trailing wheel 3, pedal plate 4, roller 5, front-wheel 6, cross bar 7 and constitute.Its vital parts roller 5, trailing wheel 3 are round-shaped, make material with steel, through casting, ground finish manufacturing.Its front-wheel 6 is round-shaped, makes material with rubber, through plastic cement shaping processing and manufacturing.Its round-shaped front-wheel 6 adopts the bearing pin coupling method to be installed on the triangular shaped main frame 1, forms the car wheel structure of a disc-shape.The roller 5 of its disc-shape adopts the bearing pin fixing means to be installed on the triangular shaped main frame 1.Form the car body drive configuration of a disc-shape.The plate 4 of pedaling of its bent stick shape adopts the bearing pin fixing means to be installed on the roller 5 of disc-shape.Form the roller drive configuration of a bent stick shape.The trailing wheel 3 of its disc-shape adopts the cross bar fixing means to be installed in the flow roll wheel 5 of disc-shape.Form a round-shaped structure of friction wheel.Its back clothes hanger 2 acts on trailing wheel 3 by the screw retention method, thereby makes trailing wheel 3 satisfy the requirement of supporting back clothes hanger 2.Its roller 5 in trailing wheel 3, drives task that trailing wheel rotate thereby roller 5 is finished by the friction car by rubbing effect.So just realized the purpose of this utility model.Easily take off chain thereby just can solve present ordinary bicycle, and take off cochain difficulty behind the chain, and the not high problem of speed.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in force, if ordinary bicycle, under certain situation, chain comes off easily, and the difficult operation of chain is gone up in the back that comes off for general people, and total handle is made dirty when changing chain, this is a thing beastly always, and then there is not this problem in new bicycle.
Embodiment 2, in force, are linked together with roller 5 owing to pedal plate 4, and when pedaling plate 4 with pedal is moving, roller 5 rotates, and 3 rotations of frictionally effect drive trailing wheel, so just solved the bothersome problem of chain on the ordinary bicycle.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with steel, rubber, utilize the basic equipment of bicycle production plant, take method stock productions such as casting, grinding, the demand with supply daily life circle so just can realize practical value of the present utility model and economic value better.
