Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of auxiliary standing, in particular to a foot -rest folding type auxiliary standing device. BACKGROUND
[0002] For a long time, patients with lower limb motor dysfunction (such as paraplegia, paraplegia patients) can only be in bed or ride a wheelchair for a long time, resulting in the patient's hip being in a compression state for a long time, which is prone to complications such as bedsores, leg muscle atrophy, osteoporosis, urinary tract infection, etc. At the same time, due to long-term sitting, cardiovascular obstruction causes cardiovascular diseases, digestive system problems, and a series of complications such as weakened heart and lung function.
[0003] To meet the needs of the market, people have invented a standing frame auxiliary standing appliance, which is suitable for SMA, DMD, cerebral palsy muscle disease, weak lower limb strength, early standing rehabilitation training of auxiliary appliances for spinal cord injury and lower limb paralysis. Its mechanism from 90 degrees to 180 degrees lying down mainly holds the handle release switch, pulls the steel wire rope, releases the locked gas spring, and then pulls the handle backward to lie down. The mechanism of the lying down steel wire rope is relatively messy and exposed outside the appliance, which is not easy to hide and is more likely to be hung with other accessories, which is not easy to arrange. CONTENT OF THE UTILITY MODEL
[0004] Therefore, the utility model aims at providing a foot -rest folding type auxiliary standing device to solve the technical problems in the above background.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a foot -rest folding type auxiliary standing device, which comprises a base with a pulley, a support assembly and an adjusting assembly installed on the base, and a support rod, the bottom end of the support rod is fixedly connected with the base, and the top end is hingedly connected with the support assembly, the adjusting assembly comprises an upper fixed block installed on the bottom of the support assembly, a lower fixed block fixedly connected with the base, a gas spring connected between the upper fixed block and the lower fixed block, and a foot -rest switch piece for controlling the extension and contraction of the gas spring.
[0006] Preferably, the top end of the gas spring is hingedly connected with the upper fixed block through a bolt, and the bottom end of the gas spring is connected with the lower fixed block through a connecting fixed block.
[0007] Preferably, the bottom end of the gas spring is fixedly connected with the connecting fixed block, and the connecting fixed block is hingedly connected with the lower fixed block through a bolt.
[0008] Preferably, the connecting fixed block is provided with a through hole for installing a foot switch piece on the end away from the lower fixed block, the foot switch piece is hinged on the through hole by a bolt, and the end of the foot switch piece in the connecting fixed block is in contact with the air valve contact of the gas spring.
[0009] The utility model discloses a foot switch piece makes the gas spring retractable, drives the conversion of the support assembly from the 90 degree standing posture into the 180 degree lying posture or from the 180 degree lying posture into the 90 degree standing posture, and the gas spring can also have the folding function without releasing the locked gas spring by pulling the steel wire rope, thereby reducing the use of steel wire rope, handle and other related accessories, reducing the processing procedure, and having the advantages of simple and quick operation, neat and tidy overall appearance, novel style and the like.
