The invention relates to the technical field of medical instruments. The invention discloses a rescue cart wheel with shock absorption damping capable of being freely adjusted according to the rotating speed. The rescue cart wheel comprises a wheel body; spokes are fixedly connected to the axis of the wheel body. Push rods are fixedly connected to the outer ends of the spokes; damping springs arefixedly connected to the bottom surfaces of the spokes; a damping pipe is movably connected to the inner ring of each damping spring in a sleeving manner; damping oil is placed in each damping pipe, abranch strip is fixedly connected in each damping pipe, a through groove is formed in the bottom end of each damping pipe, a rack is movably connected in a groove body of each through groove, a gearring is movably connected to the inner ring of the bottom face of each damping pipe in a sleeving mode, and a baffle is fixedly connected to the bottom end of each rack. The rescue cart with shock absorption damping capable of being freely adjusted according to the rotating speed of the wheels has the advantage that the effect of automatically adjusting the shock absorption damping according to the rotating speed of the wheels is achieved through cooperative use of the racks, the gear rings, the baffles, the gears, transmission springs, the arc grooves, reset springs and heavy blocks.
