Abstract

A multifunctional electric nursing frame is composed of a bottom frame, a lifting mechanism and a mechanical arm looping mechanism. Except for pushing depending on manpower, other actions are completed through four electric pushing rods and a motor, and the bottom frame is provided with a push-and-pull type pedal plate and a bottom frame stretching device. A lifting stand column is fixedly provided with a kneecap telescopic support, and the electric pushing rods provide power to complete double-mechanical-arm looping through a three-piece linkage structure. The bottom frame stretching device can enlarge the supporting area of the bottom frame, and meanwhile the multifunctional electric nursing frame can pass through a door with the same width with the human body when pushed indoors. The downward bending design of a lifting bent arm and a groove at a right angle increase the effective lifting size. The pedal plate and a kneecap can enable the nursing frame to obtain the moving function and can help to conduct walking and upright train. Labor intensity of nursing workers is lowered to the maximum, and safety in a nursing process is improved.
