Description

Technical Field

[0001] The utility model relates to the technical field of power-assisted walking, and in particular to a power-assisted walking device for geriatrics. Background Art

[0002] The growing population is bound to lead to the emergence of aging. With the increase of age, the physiological functions of the human body in all aspects decline, the irritability and reflexes decrease, and the human body functions decline, especially in walking. The body lacks qi and blood, and the meridians and blood vessels in the body are blocked by waste substances, cold and dampness, toxins, etc., which slows down the circulation of qi and blood, resulting in a lack of qi and blood energy support for the muscles and tendons of the legs and feet, resulting in the degeneration of leg and foot functions and reduced endurance, which manifests as weakness in the legs and feet, and then difficulty in walking. The power-assisted walking devices in related technologies can only help the elderly to walk, but in real life, the elderly with mobility problems have complicated conditions when walking, and they do not always have objects to support them. When the elderly with mobility problems have no objects to support them, they are prone to fall sideways, and the elderly's bodies are relatively fragile. Once a fall occurs, it is very easy to be in danger.

[0003] The utility model with authorization announcement number CN114099251A in the prior art is named as: A walking aid for the elderly, comprising: the thigh support rod is hinged to the calf support rod; the shoe support is rotated on the side support block, the shoe strap is arranged on the shoe support, and the side support block is rotatably installed at the bottom of the foot support rod; the auxiliary standing mechanism is arranged on the inner side of the calf support rod and the thigh support rod, and the supporting mechanism is arranged on the lower side of the thigh support rod. The overall connection of the equipment cooperates with three fixing methods, so that the elderly can stand more stably and the side can stand more stably. The support block increases the contact area between the soles of the elderly's feet and the ground, further ensuring the stability of the elderly when standing or walking, and at the same time cooperates with the vertical foot support rod to prevent the elderly from falling sideways, providing protection for the safety of the elderly when walking or standing. However, the new waist support and thigh support rod are connected by bolts, which are not easy to disassemble and assemble. When the waist support is damaged, it cannot be quickly replaced in time, and there is no anti-skid component on the bottom of the support block, which makes it easy to fall when walking on a smooth road. There are problems of slow disassembly and assembly and poor anti-skid performance. Summary of the invention
