Bidirectional screw rod device and care sickbed lifting device

Abstract

The invention provides a bidirectional screw rod device and a care sickbed lifting device, and belongs to the field of transmission devices. The bidirectional screw device comprises a screw rod body, a left-handed assembly and a right-handed assembly, wherein a left-handed thread and a right-handed thread are arranged at the two ends of the screw rod body respectively; nut fixing baffle blocks are arranged on the screw rod body; the left-handed assembly comprises a left-handed nut and a limiting slide block; the right-handed assembly comprises a right-handed nut and a limiting slide block. The bidirectional screw rod device is quite steady to use, free of noise, good in using effect and long in service life. The care sickbed lifting device comprises a bedstead and a base, wherein two lifting connecting rod assemblies are symmetrically arranged on the two sides of the base; the upper end of each lifting connecting rod assembly is hinged to the bedstead, the lower end of each lifting connecting rod assembly is hinged to the base, and the bidirectional screw device is arranged between the two lifting connecting rod assemblies. During the use, the care sickbed lifting device does not generate noise in the lifting process, so that rest of a patient is not affected, a good rehabilitating environment can be provided for the patient and the patient can heal faster.

Description

technical field [0001] The invention relates to the field of transmission devices, in particular to a two-way screw device and a lifting device for a monitoring bed. Background technique [0002] The screw rod is a commonly used transmission device in the mechanical field and other fields. The existing screw rod has a simple structure, relatively unstable transmission effect, high noise during transmission, easy damage, and short service life. [0003] The monitoring bed is one of the commonly used equipment in the medical industry, which is used by patients during recuperation or treatment. In many cases, it is necessary to adjust the height of the patient to cooperate with other equipment or medical personnel for treatment, so it is often necessary to use a liftable monitoring bed. [0004] Most of the existing liftable monitoring beds use lifting rods to realize the lifting function of the monitoring bed. This type of monitoring bed has a simple structure, and the bed fr...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing liftable monitoring beds use lifting rods to realize the lifting function of the monitoring bed. This kind of monitoring bed has a simple structure, and there is a horizontal displacement of the bed frame before and after lifting, which brings more inconvenience to the medical care process.

Especially for critically ill patients, the body is full of various tubes, and the involvement of the horizontal movement of the bed frame will cause serious consequences and affect the patient's recovery

[0005] Moreover, the base of some monitoring beds is fixed on the ground, and one end leans against the wall. The bed frame will have a horizontal displacement during the process of rising, and due to the resistance of the wall, this part of the displacement will pass through the inside of the monitoring bed. The dislocation or deformation of the structure can be used to offset; after multiple lifts, the internal parts of the monitoring bed are very easy to loosen, and desoldering and wire detachment are likely to occur, which will seriously lead to the collapse of the bed frame and bring fatal trauma to the patients on the monitoring bed
