This invention discloses an oil-free floor spring, i.e., a floor spring that operates without machine oil, relating to the field of floor spring technology. It includes a mounting box and a panel, the panel being fixedly mounted on the mounting box. A mounting base is fixedly mounted inside the mounting box, and a shaft cover plate is fixedly mounted on the mounting base. This invention achieves the effect of adjusting the extension and retraction speed of the telescopic cylinder by controlling airflow, thus avoiding the use of machine oil as the control medium. This solves the problems of existing floor springs, which, due to their annular oil circuit and use hydraulic oil as the control medium, may leak oil and lose performance after long-term use due to aging of seals or mechanical wear. This can cause the door to close too quickly due to uncontrolled movement, potentially injuring people. Furthermore, because the interior is filled with machine oil, there is a possibility of explosion, oil spraying, and combustion in the event of a fire, posing a danger to human life. Additionally, in extreme low-temperature environments, the viscosity of the oil may change, leading to excessively slow or stopped closing speeds.
