Treadmill motion buffering device

Abstract

A treadmill motion buffering device comprises a hinge support, a running pedal, a spring and a spring pressure rod. One end of the running pedal is hinged to the hinge support. The treadmill motion buffering device further comprises a connecting rod, a left fixing support and a right fixing support, wherein the left fixing support and a right fixing support are used for limiting the spring and causing the spring to only bear the horizontal direction force, the other end of the running pedal is hinged to one end of the connecting rod, the other end of the connecting rod is hinged to one end of the spring pressure rod, and the spring pressure rod sequentially penetrates the right fixing support, the spring and the left fixing support. One end of the spring is fixedly positioned on the spring pressure rod, and the other end of the spring is in contact with the left fixing support. In a state of enabling the pedal to bear the acting force, the acting force is transmitted to the spring pressure rod through the connecting rod and drives the spring pressure rod to move towards one side of the left fixing support and compresses the spring so as to achieve the motion buffering of the running pedal. According to the technical scheme, the treadmill motion buffering device has the advantages that the gravity is converted into horizontal force, the spring only bears pressure and does not bear bending moment, and the service life of the spring is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a treadmill motion buffer device. Background technique [0002] With the improvement of living standards, people's pursuit of health is becoming more and more urgent, and people's investment in health is also increasing. As one of the most effective fitness equipment, the treadmill has entered ordinary families and has become one of the standard equipment in the gym. Although there are many kinds and models of treadmills at present, the basic principles and structures of the mechanical parts are basically the same, except that the control functions realized by the electronic control devices are different. At present, people's demand for treadmills is no longer satisfied with the ability to run, count or diversify functions, but to pay more attention to the appearance, quality, quality and comfort of products. Therefore, in the design of the mechanical structure of the...

Problems solved by technology

But this structure also has obvious defects: the pressure on the spring does not coincide with the axis of the spring, but tilts at a certain angle. This pressure can be decomposed into a separation parallel to the axis of paralysis and a component force perpendicular to the axis of the spring.

The result is a spring that is poorly cushioned and fails quickly
