Universal wheels are located at one end of the base's underside, and support legs are located at the other end. The support legs are threadedly connected to the base and are also provided with adjustment wheels. The lifting mechanism comprises a lead screw, a lifting rod, an outer tube, a slider nut, and a drive motor. An upper end cap is located at the upper end of the outer tube, and a through-hole is provided in the middle of the upper end cap for the lifting rod to pass through. This cardiology bed automatically adjusts its height through the lifting mechanism. The support legs support and secure the bed, allowing it to be adjusted to the optimal position for patients of varying body shapes, facilitating diagnosis and treatment, reducing the burden on doctors, and simplifying operation.
