Abstract

The graduation design multi-function treadmill according to their own situation, appropriate choice of exercise to exercise on the heart and lung function and muscle strength of upper and lower limbs has a good effect. In the user’s time, space is more saved, so that the multi-purpose treadmill has a better use.

This topic is to carry on the multi-function treadmill appearance and the structure design. Designed multi-function treadmill, including general function design, transmission mechanism design, shape structure design, front and rear roller design. Because the electric treadmill has a lot of electronic auxiliary equipment, the practitioner can experience different running environments, such as running on the ground, running up the slope, running in the hills, running in the variable speed, and so on. The individual can exercise according to the purpose of his exercise. The treadmill can show the running speed, time, heart rate, heat, beat, distance and so on, so that the fitness person can adjust the training intensity according to their physical condition at any time.

Key words: running board; multi-function; overall structure; transmission mechanism
