Caster lifting device and nursing bed

Abstract

The invention discloses a caster lifting device capable of lifting a caster, and a nursing bed comprising the caster lifting device. The caster lifting device comprises a rotating joint, the caster, a lifting shaft, a fixed shaft sleeve, a transmission shaft and a braking rod, wherein the transmission shaft penetrates through the fixed shaft sleeve transversely; the braking rod is matched with the end part of the transmission shaft; the upper part of the rotating joint is rotatably matched with the lower part of the lifting shaft; the lifting shaft penetrates into the fixed shaft sleeve and is movably matched with the fixed shaft sleeve; the two sides of the fixed shaft sleeve are provided with lifting driving components; each lifting driving component comprises an upper swinging piece, a lower swinging piece and a connecting rod; the two side walls of the fixed shaft sleeve are provided with lifting grooves; the connecting rods penetrate through the lifting shafts transversely and the two ends of the connecting rods extend out of the lifting grooves at the two side walls of the fixed shaft sleeve respectively and are connected with the lower swinging pieces; one end of each upper swinging piece is matched with the transmission shaft, and the other end of each upper swinging piece is movably connected with the lower swinging piece; the outer wall of the fixed shaft sleeve is fixedly matched with a fixed bracket which is provided with a limiting part; and the part where the upper swinging pieces and the lower swinging pieces are movably connected corresponds to the position of the limiting part. The invention is applied in the field of the nursing bed.

Description

Technical field [0001] The invention relates to a caster lifting device and a nursing bed. Background technique [0002] Nursing beds are one of the most common medical devices, and they have become more and more widely used in many families and become common equipment for home care. With the advancement of science and technology, the structure of nursing beds has been continuously optimized and updated. At present, the types of nursing beds There are many kinds of nursing beds, and their technology is becoming more and more mature. However, most of the existing nursing beds have improved the lifting and folding of the bed body, but the foot of the bed still uses traditional technology. There are two main types of traditional bed feet, one Fixed feet are used, and the other is casters. Among them, the use of fixed feet can make the nursing bed more stable, but it is extremely inconvenient to move and cannot be moved flexibly. When moving, it requires manpower to carry and lift, w...

Problems solved by technology

[0002] Nursing bed is one of the most common medical devices. It has become more and more widely used in many families and has become a common equipment for home care. With the advancement of science and technology, the structure of nursing beds has also been continuously optimized and updated. At present, the types of nursing beds There are many types of nursing beds, and their technologies are becoming more and more mature. However, most of the existing nursing beds have improved the lifting and folding of the bed body, but the traditional technology is still used for the foot of the bed. There are mainly two types of traditional bed feet, one One is to use fixed feet, and the other is to use casters; among them, the use of fixed feet can make the nursing bed more stable, but its movement is extremely inconvenient and cannot be moved flexibly. When moving, it requires manpower to carry and lift, causing inconvenience in use; If the caster method is used, it can move flexibly, but it is easily affected by the rotation of the pulley, causing the nursing bed to be placed unstable and prone to shaking. A slight external force may cause the overall displacement of the nursing bed, so it is easy to affect the use effect. have adverse effects, and currently there is no device that can lift the casters to be used in nursing beds

[0003] To sum up, the nursing beds in the prior art cannot take into account stable placement and flexible movement, and there is a technical defect of inconvenient use
