Description
Technical field
The utility model relates to bicycle, is specifically related to a kind of folding sport and body-building bicycle.
Background technology
Be accompanied by growth in the living standard, people more and more pay attention to the quality of living, and also more and more pay attention to health problem.Exercise and fitness equipment becomes the necessary article of people's daily life.Traditional body-building apparatus is generally in indoor use, and people can't enjoy outdoor fresh air and natural beautiful scenery in sport and body-building.These equipment have also taken indoor big quantity space simultaneously.So simple, practical, light exercise and fitness equipment just becomes very exigence of people.
China is world-famous " bikedom ", has maximum in the world bicycles and maximum bicycle users.But for many years, the 26S Proteasome Structure and Function of bicycle does not have great change, and it is more reasonable that society presses for structure, the bicycle that function is more various,
The employed vehicle of people are along with the progress of society and expanding economy and very big variation has taken place, in some large-and-medium size cities, be accompanied by the high speed development of traffic especially, the rapid of private car popularized, bicycle no longer has been the topmost vehicle, and its Occupation coefficient is in continuous reduction.But as a kind of environmental protection with respect to private car, energy-conservation, the convenient stop, the user is required the lower vehicle, bicycle still has very big value of service.So, the not high bicycle of Occupation coefficient in many families, occupation space just exists contradiction when idle.People wish to have a kind of when depositing the littler bicycle of volume.
Simultaneously, people such problem occurs through regular meeting when using transit trip, oneself set out or website that the place that arrives can provide with public transport between or change between website and exist certain distance.If this segment distance adopts the mode of walking will take a large amount of time of traveler equally, the way one of improvement is the development of public transport, is that traveler is carried a kind of vehicle that are used for riding instead of walk on the one hand in addition.The folding bicycle that several styles occur is gone up by society at present, and folding mode is not quite similar, but shortcoming is that the car fold mechanism that has is not simple and direct, wastes time and energy when folding; The car folded form defectiveness that has does not form the volume of an optimization after car is folding; Simultaneously, the Folding Bicycle that also lacks multi-functional movable body-building at present
Summary of the invention
It is a kind of simple, practical, light that the purpose of this utility model is to provide, the multi-functional exercise and fitness equipment that can use out of doors---collapsible sport and body-building bicycle.
The purpose of this utility model is achieved through the following technical solutions.
Collapsible sport and body-building bicycle comprises: front-wheel, trailing wheel, handlebar, vehicle seat, pedal, driving system and brake system, the trapezium structure that its main framing is made up of preceding wheeling supporting frame, back wheeling supporting frame, entablatrance and cross sill.Wherein, preceding wheeling supporting frame in trapezoidal and back wheeling supporting frame respectively are a homogeneous tube; Preceding the same crossbeam of wheeling supporting frame is that fixed type connects, and its excess-three point of connection is that hinge type connects, and cross sill is the folding structure of two-section, is that hinge type connects between the two-section.
Back wheeling supporting frame top is connected with a leg-of-mutton vehicle seat support.The vehicle seat support is made up of telescopic sleeve pipe, cover pipe connections and vehicle seat attaching parts.Telescopic sleeve pipe comprises an outer tube and the interior pipe that can stretch in outer tube.The interior pipe top of telescopic sleeve pipe is equipped with vehicle seat.The vehicle seat attaching parts links together interior pipe and back wheeling supporting frame, and the junction is hinge type and connects.Cover pipe connections one end cuff is on the wheeling supporting frame of back, and the outer tube bottom hinge type of the other end and telescopic sleeve pipe is connected.
Collapsible sport and body-building bicycle has driving system efficiently, is made up of the secondary sprocket drive system.It comprises a drive sprocket, a driving chain wheel and a driven sprocket, between drive sprocket and driving chain wheel, link transferring power by chain between driving chain wheel and driven sprocket.
The collapsible sport and body-building bicycle of the utility model, as a kind of be the folding portable bicycle of main purpose with body-building, it has comprised the basic function of standard bicycle as a kind of vehicle, combining the advantage of bicycle and the function that common body-building apparatus clocked, remembered speed, note mileage simultaneously, is a kind of sports health product that combines with leisure of brand-new practicality.About 4.5 kilograms of its weight is launched and the folding time only used for 5 seconds.And have brand new transmission and brake system, and guaranteed the proper motion speed under the little situation of wheel volume, simple and compact for structure, brake safer.Small and exquisite attractive in appearance, have very strong recreational.Simultaneously, when short distance is gone on a journey, can be used as transportation means and use, solved the problem of riding instead of walk in inaccessible distance in bus station and highway section.The design of closed type chain-wheel box all is closed in wherein all transmission components, has effectively avoided lubricating oil on use, handling process middle sprocket, chain to the pollution of user's skin.Circle formula brake facing brake system simplifies the structure, and is more safe and reliable.
