Description

active flexion machine

technical field

The present invention relates to an active bending and stretching fitness equipment. Its structure is not only safe, but also light in weight and easy to move and use. The combination method is based on the cooperation of studs and slot holes, which can be combined quickly. After dismantling, it can achieve the effect of storage.

Background technique

With the changes of the times, the acquisition of knowledge has become quite easy. Due to the full exchange of knowledge, the progress of society has advanced by leaps and bounds, and the rapid evolution of social forms has also caused many negative effects. First of all, with the development of science and technology, the use of automation Machinery replaces manpower, and means of transportation forms a substitute for transportation, and urbanization replaces rural areas, which reduces the space for people to move around. In addition, economic growth further drives inflation and increases prices, making people have to spend more time. Work and various developments have led to long-term lack of exercise among Chinese people, resulting in many civilized diseases in recent years. Many Chinese people who have noticed that their physical condition has deteriorated are unable to go out for outings or go for a run in the sports field because of their busy lifestyle. Therefore, many indoor fitness equipments appear on the market, which have the effect of exercise while keeping fit, and there are quite a lot of common fitness equipments. Among them, an existing bending and stretching fitness equipment is to use both hands and both hands. The stretching of the feet pushes and pulls the body and slides on the fitness equipment to achieve the effect of whole-body exercise. It is made of metal and must be equipped with a power regulator for auxiliary use, and the power regulator can be a hydraulic cylinder or a pull wheel to reduce the force of operation, and this structure is too heavy and costly. It is inconvenient to move and use, and the combination of the bending and stretching fitness equipment is fixed by bolts, which takes up a lot of space when it is not in use, causing troubles in storage.

In view of this, the inventor has accumulated many years of experience in the manufacture, development and design of related products. Aiming at the above-mentioned objectives, after detailed design and careful evaluation, he finally obtained a practical invention.

There is an existing flexion and extension exercise device, which is made of metal material and must be equipped with a power regulator for auxiliary use, which makes the structure too heavy and expensive, and it is difficult to move and use. The above causes a lot of inconvenience, and the combination of the bending and stretching fitness equipment is fixed by bolts. When it is not in use, it seems to take up a lot of space, so it causes troubles in storage. This is the technical problem that the present invention intends to solve.
