Lifting-and-descending type medical treatment bed

Abstract

The invention relates to a lifting-and-descending type medical treatment bed, which comprises support legs, a bed frame arranged on the support legs and a mattress located on the bed frame, wherein a lifting and descending assembly is arranged between the bed frame and the support legs; the lifting and descending assembly comprises guide rails parallelly arranged on two support legs at both sides of the bed frame and screws capable of sliding in the guide rails; two screws are arranged in each guide rail; each screw is hinged with one end of a connecting rod, and the other end of the connecting rod is hinged under the bed frame; each screw is socketed on a rotation shaft; one end, extending out of the guide rail, of each rotation shaft is fixedly connected with a chain wheel; two chain wheels at the head of the bed frame are respectively connected with two chain wheels at the tail of the bed frame through chains; and a crank handle is arranged on each of one of two chain wheels at the head of the bed frame and one of two chain wheels at the tail of the bed frame. The lifting-and-descending type medical treatment bed provided by the invention has simple structure and ingenious design; and the height of the bed frame of the medical treatment bed can be adjusted through operating the crank handles by hands, thus the patients can conveniently go to bed or get out of the bed and medical care is facilitated; and in addition, the inconsistency in the height of the head and tail of the bed frame can be realized, therefore, the medical treatment bed is particularly convenient.

Description
