Automatic protection mechanism on running machine

Abstract

The invention discloses an automatic protection mechanism on a treadmill, which comprises a treadmill platform, brackets and first springs, and further comprises a connecting rod for connecting the brackets on the two sides; the adjusting device is arranged on the connecting rod and comprises a movable supporting seat, and a first spring is arranged between the supporting seat and the treadmill; a driving block and a driving rod are arranged in the driving device, so that the driving device is connected with the treadmill; the connecting pipe is connected with the adjusting device and the driving device. Water in the driving device is driven to be conveyed into the adjusting device through vibration of the treadmill, when the conveying amount is larger than the outflow amount, the supporting base drives the spring to move, the deformation amount generated by the spring is changed, when the supporting base extrudes the pressed plate, the rotating shaft rotates, the adjusting block is pulled through the pull rope, and the output amount is made to be the same as the outflow amount; the driving block moves upwards to open the first one-way valve and moves downwards to close the first one-way valve, the second one-way valve feeds water into the adjusting device under pressure, and the third one-way valve feeds water into the driving device through the 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 common fitness equipment in gyms, and they are the simplest type of fitness equipment today, making them the best choice for fitness equipment in gyms. [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 will not only shorten the service life of the spring, but also cause damage to the user's knee due to excessive vibration. Contents of the invention [0004] Aiming at 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 traditional treadmill. [0005] The technical solution adopted ...
