Device for automatically adjusting speed to guarantee position safety during exercise on running machine

Abstract

The invention relates to the technical field of fitness services, and discloses a device for automatically adjusting speed to guarantee position safety during exercise on a running machine. The device comprises a shell, wherein a running belt is movably connected to the upper end of the shell, a driving shaft is movably connected to the right end of the running belt, a supporting block is movably connected to the lower end of the driving shaft, the right end of the supporting block is movably connected with an extension spring, the lower end of the supporting block is movably connected with a connecting rod, the lower end of the connecting rod is movably connected with a pushing rod, the left end of the pushing rod is movably connected with a moving block, and the upper end of the moving block is fixedly connected with a guide column. A control disc is driven by a transmission rod to move downwards together, so that the control disc exerts downward force on the lower end of the running belt, the friction force between the control disc and the driving shaft is increased, the movement speed of the running belt is reduced, and when the speed of a human body is not equal to the speed of the running machine, the speed of the treadmill is automatically reduced.

Description

technical field [0001] The invention relates to the technical field of fitness services, in particular to a device for automatically adjusting speed and ensuring position safety when exercising on a treadmill. Background technique [0002] With the gradual development of society, people's living standards have been significantly improved, so that people gradually pay attention to their own physical fitness. The use and application of fitness equipment can reasonably exercise the various structures of the body. [0003] However, there are still defects that need to be overcome in the operation of the treadmill in the gym. The treadmill can save space and can adjust the multi-level speed at the same time, so it is the most equipment in the gym. , the speed gradually cannot keep up with the speed of the treadmill, so it is easy to step into the air and fall off the treadmill, causing certain dangers. At the same time, when the speed is adjusted, when the friction is too large,...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for automatically adjusting the speed to ensure the safety of the position when exercising on the treadmill. When the friction between the running belt and the drive shaft increases, it will automatically lubricate the connection to prevent mechanical wear and tear. It is easy to step on the air and fall off the treadmill, causing certain dangers. At the same time, when adjusting the speed, when the friction force is too large, it is easy to cause mechanical wear problems
