Abstract
A kind of recreation and body-building bicycle, vehicle frame, handlebar, front-wheel, rear-wheel, active wheel disc, flywheel, chain, pedal and vehicle seat, pedal is connected on axis by short crank, the active wheel disc is fixedly connected with axis, flywheel is fixedly connected with rear-wheel, chain is connected between active wheel disc and flywheel, it is made of gusseted the center of vehicle seat, middle axis center, 3 points of rear-wheel axis center, is set as 20 ° ~ 50 ° by the angle that vertex is formed of middle axis center in gusseted to be constituted the load stability triangle structure that centre of gravity is ridden.Vehicle seat rear portion is equipped with backrest.Using short crank, the structure of riding of centre of gravity, and the saddle widened is used, the fatigue strength of muscle when riding can be substantially reduced, avoid causing to damage to knee endoprosthesis, riding reduces consumption in vivo when doing work identical, improve comfort level.The chances that many and the Nature is got close to and the enjoyment ridden are increased, are a kind of can ride instead of walk and the recreation and body-building bicycle of movable body-building.
Description
Technical field
The utility model relates to a kind of exercise and fitness equipment, especially a kind of recreation and body-building bicycle.
Background technique
Recently, modern gradually gets higher the care of health, and also gets higher to the care degree of grossness and the bodily form, thus positive stream
Row weight-reducing heat.By cycling, the movement of appropriate intensity promotes cardiovascular movement, accelerates metabolism, enhances heart
And lung functions are more and more paid attention to so as to improve the constitution of human body.Common bicycle is more as a kind of friendship
Logical tool is using, and special Exercycle is all fixed at home or in gymnasium, and has lacked many and the Nature parent
Close chance and the enjoyment ridden.
Summary of the invention
The technical problems to be solved in the utility model is that in view of the deficiencies of the prior art, proposing one kind can ride instead of walk and can
The recreation and body-building bicycle of sport and body-building.
The technical problems to be solved in the utility model is achieved through the following technical solutions, and a kind of recreation and body-building are voluntarily
Vehicle, vehicle frame, handlebar, front-wheel, rear-wheel, active wheel disc, flywheel, chain, pedal and vehicle seat, its main feature is that: pedal passes through short crank
It is connected on axis, the active wheel disc is fixedly connected with axis, and flywheel is fixedly connected with rear-wheel, and chain is connected to driving wheel
Between disk and flywheel, gusseted is made of the center of vehicle seat, middle axis center, 3 points of rear-wheel axis center, in gusseted in
Axis center is that the angle that vertex is formed is set as 20 °~50 ° to constitute the load stability triangle structure that centre of gravity is ridden.
The technical problems to be solved in the utility model can also further realize by the following technical programs, the short song
Handle is the adjustable structure of 6~13cm of length.
The technical problems to be solved in the utility model can also further realize by the following technical programs, the vehicle seat
Including vehicle seat ontology, backrest is equipped in vehicle seat rear body.
The technical problems to be solved in the utility model can also further realize by the following technical programs, the backrest
Equipped with backboard, the front of backboard is equipped with flexible back cushion, and backboard is connected by bracket with vehicle seat ontology.
The technical problems to be solved in the utility model can also further realize by the following technical programs, vehicle seat ontology
Equipped with the saddle type pedestal widened, length-width ratio is 1:0.8~1.2.
The utility model compared with prior art, using short crank, the structure of riding of centre of gravity, and has used and has widened
Saddle, the fatigue strength of muscle when riding can be substantially reduced, avoid causing to damage to knee endoprosthesis, drop when doing work identical of riding
Low internal consumption improves comfort level.The chance that many and the Nature is got close to and the enjoyment ridden are increased, is that one kind can ride instead of walk
The recreation and body-building bicycle of movable body-building again.
Detailed description of the invention
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is vehicle seat ontology top view.
Specific embodiment
The specific technical solution of the present invention described further below, in order to which those skilled in the art is further understood that
