Description

Wind resistance fitness device with air intake volume adjustment mechanism

The invention relates to the technical field of fitness devices, in particular to a wind resistance fitness device with an air intake volume adjustment mechanism.

As the concept of sports and fitness in modern society is becoming more and more popular, related fitness equipment has been introduced with the public's sports concept. In order to facilitate indoor exercise, both exercise bikes and rowing machines have become the favorite sports of users. In addition, in order to allow users to obtain the training effect and fun produced by different resistance sizes, sports equipment in the market provides fitness equipment that generates resistance in a variety of ways, so that users can experience different fitness experiences.

In the above, taking the wind resistance exercise bike as an example, please refer to FIG. 1A and FIG. 1B , the wind resistance exercise bike 10 mainly includes a bracket 11 , a fan wheel 12 , a wind resistance adjusting device 13 and a chain 14 , and the fan wheel 12 is arranged on the The bracket 11, the wind resistance adjustment device 13 is rotatably arranged on the bracket 11, the wind resistance adjustment device 13 includes a rotating shaft 131, an outer wheel 132 and a plurality of wind resistance plates, the rotating shaft 131 is rotatably arranged on the bracket 11, The outer wheel 132 is disposed on the rotating shaft 131 , the wind resistance plates are formed at intervals on the outer edge of the outer wheel 132 , the chain 14 is connected to the fan wheel 12 and the wind resistance adjusting device 13 , the user can exercise by stepping on the fan wheel 12 .
