Description of the Invention: [Technical Field] The invention belongs to the technical field of volume reduction of a fitness equipment, and specifically refers to a coaxial structure of a crank and a load wheel which can be coaxially actuated and has a speed increasing effect, thereby Effectively reduce the size of fitness equipment and increase the flexibility of space application for storage and transportation. [Prior Art] According to the influence of environmental changes, the places available for people to exercise and the time of sputum are becoming more and more limited. Due to the reduction of exercise time, it directly affects people's physical and mental health. According to the research report, A small number of and multiple movements, the effectiveness of preventing heart disease is as good as the intensive exercise for a long time. Therefore, in order to solve the above-mentioned problems that affect the physical and mental health due to insufficient exercise, there are various types of development on the market. Sports fitness equipment with different functions, which allows people to exercise and exercise anytime and anywhere; but taking the common exercise bike and sugar round machine as an example, the traditional exercise bike and elliptical machine are mainly based on the consideration of sports load. The crank frame is provided with a crank set for the user to step on, and the crank set can drive a damping load wheel (such as an external magnetic member, an inner magnetic member or a friction wheel) through an integral driving wheel to utilize the load. The weight or damping of the wheel to generate the motion load 'for the effect of motion; in the structural design, such as the load wheel and the curve If the group is set to be concentric, and the load wheel is directly actuated by the crank group, there will be a problem of insufficient inertia acceleration, and the load is too large to be suitable for the use of the elderly and the use of the rehabilitation person's inconvenience and movement affecting the drive. The effect of the current design is that the design of the crank handle group and the load wheel are different from each other. For example, the "walking exercise device" of the Chinese Patent No. 319088, etc., 4 201028188 • However, such a design would increase the fitness equipment. The volume, the invisible space also increases the space for transportation and storage. At the same time, due to the excessive volume, the inconvenience caused by consumers at home is affecting the purchasing intention and reducing the economic benefits of the fitness equipment. To this end, the industry is actively seeking to reduce the size of fitness equipment under the same sports effect. For example, in our patent No. 1280008, we can see that the above-mentioned practices are constantly shortened. The wheelbase between each axis and the height of the actuating rod are used to achieve the purpose of reducing the volume. However, due to the limitation of the processing technology and the radius of rotation of the actuator, the volume that can be truly reduced is limited and cannot satisfy the consumers. The demand is still to be further improved. = In fact, the most effective way to reduce the size of such fitness equipment with load wheels is to make the passive load wheel and the driven crank set coaxial, so that it can really reduce the volume, so how to solve the coaxial The problem of insufficient inertia acceleration and excessive load is to solve this problem. In view of this, the present inventors have intensively discussed the problem of excessive size of the aforementioned existing exercise equipment, and have been engaged in research and development and related experience of related industries for many years, and actively seek solutions, and have been continuously researching and trialing. Finally, the invention was successfully invented—the same kind of reduction of the crank and the wheel used for the fitness equipment, and the inconvenience and trouble of the inertia acceleration by the *, , and the method when the existing crank and the idler wheel are coaxial. SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to provide a coaxial structure when a crank and a load are used, so that the crank can drive the coaxial load wheel, and the small volume of the 201028188 wheel and the motion maintaining effect have an inertial acceleration effect. And achieve the performance. Practice 2 == month mainly through the following technical means, to achieve the purpose and effectiveness of the description: it contains.
