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...
