An automatic protection mechanism on a treadmill

Abstract

The invention discloses an automatic protection mechanism on a treadmill, comprising a treadmill, a bracket, a first spring, and further comprising: a connecting rod for connecting the two sides of the support; an adjusting device, which is arranged on the connecting rod and includes a movable support The seat, the first spring is arranged between the support seat and the treadmill; the drive device, a drive block and a drive rod are arranged in the drive device to connect with the treadmill; the connecting pipe connects the adjustment device and the drive device. The vibration of the treadmill is used to drive the water in the drive device to the adjustment device. When the conveying volume is greater than the outflow, the support seat drives the spring to move, changing the amount of deformation generated by the spring, and when the pressure plate is squeezed by the support seat, the rotating shaft is moved. Rotate and pull the adjustment block by pulling the rope, so that the output volume is the same as the outflow volume. Set the drive block to move up to open the first one-way valve, move down to close the first one-way valve, and set the second one-way valve to be pressurized. Water is supplied to the regulating device, and a third one-way valve is arranged to supply water to the driving device through a water pump.

Description

technical field [0001] The invention relates to the field of treadmills, in particular to an automatic protection mechanism on the treadmill. Background technique [0002] Treadmills are a common piece of fitness equipment in gyms, and one of the simplest ones available today, making them the best choice for fitness equipment in the gym. [0003] The springs on the traditional treadmill are in a fixed state. When the user runs fast on the treadmill, the pedaling force generated by the user greatly exceeds the pedaling force when walking or jogging. Excessive deformation not only results in a shortened lifespan of the spring, but vibrations of excessive magnitude can also cause damage to the user's knee. SUMMARY OF THE INVENTION [0004] In view of the deficiencies of the prior art, the present invention provides an automatic protection mechanism on a treadmill, which can effectively solve the above-mentioned problems existing in the conventional treadmill. [0005] The t...

AI Technical Summary

Problems solved by technology

[0003] The springs on traditional treadmills are all in a fixed state. When the user runs fast on the treadmill, the pedaling force generated by the user is much higher than that of walking or jogging. Excessive deformation not only shortens the service life of the spring, but also causes damage to the user's knees due to excessive vibration
