Description

An environmentally friendly treadmill

technical field

The utility model relates to a leisure entertainment health care equipment, in particular to an environment-friendly treadmill.

Background technique

The treadmill enables people to run or walk in a relatively fixed position, and realize fitness and health by exercising the body. At present, there are two types of treadmills for families or gyms on the market. One type is driven by electric motors. The main defects are: one is expensive, the other is that it depends on the power supply, and it cannot be used when the power is off; the third is that it has a single function. . The second type is a mechanical treadmill. This type of treadmill does not need to be driven by electricity. The frictional and inertial forces between the foot and the running belt make the running belt rotate continuously around the rollers. When running and walking on the running belt, it is necessary to have a certain inclination angle from the foot to the back pedal. Due to factors such as the age and gender of the exerciser, the exerciser has different requirements for the inclination of the running belt. Most existing treadmills cannot Adjust the tilt. Because the driving force of the running belt rotation is generated by the exerciser running or walking on the running belt, the force generated when the foot pushes back, the friction force and inertial force between the exerciser's foot and the running belt, etc., may There will be a situation where the speed of the running belt is inconsistent with that of the runner. When the speed of the running belt is greater than the speed of the runner, it may cause unsafe conditions for the runner. At this time, the speed of the running belt cannot be adjusted immediately only by adjusting the running speed .
