This utility model belongs to the field of electric bed technology, specifically an internal roller guide structure and an electric bed with abdominal relief function. The internal roller guide structure includes a fixed tube, a movable tube, and rollers. One end of the movable tube is inserted into the fixed tube. The rollers are located inside the fixed tube, and two pairs of rollers are spaced apart on the movable tube to support the extension and retraction of the movable tube within the fixed tube. This utility model's internal roller guide structure is simple in structure and flexible in operation. When applied to an electric bed, the extension of the movable tube allows the backrest board to shift backward, releasing the pressure exerted by the mattress on the body and improving comfort.
