Description

Mattress capable of lifting left or right

Technical Field

The invention relates to beauty treatment, massage and physical therapy, in particular to a method for operating a control handle rod which is operated by a single hand to pull to the left or right when a worker needs to change positions of the back and the side of the body and change clothes and trousers or a bed sheet, the square lock column on the left side or the right side slides outwards to expose the round lock column on the left side or the right side of the front and rear main mattress assembly. At this time, a worker holds the rotary handle of the square rotary operating head by one hand or is designed into an electric type and rotates a telescopic cross universal joint, and the telescopic cross universal joint rotates to drive the hand-operated jack; when the hand-operated jack is lifted upwards, the main mattress assembly can safely obtain the left side or the right side lifting according to the requirements of workers to obtain the function of the side body of the main mattress assembly, so that the workers can easily turn over the side body, change the back side body of the workers, and change clothes and trousers or bed sheets on the side body of the workers in the aspects of beauty treatment, massage and physical therapy, particularly in the aspects of helping the workers with inconvenient actions to easily turn over the side body; in particular to a mattress which can be lifted from the left or the right.

Background

The method comprises the steps that firstly, workers move the people with mobility disabilities to turn over the sides with two hands to change the positions of the backs and the positions of the clothes and the trousers or the bed sheets, and secondly, the people with mobility disabilities use pillows to push one side of the back to change the positions when the positions of the backs are needed; however, the working method has the defects that the working intensity of workers is high, and when the heads of the workers are high and small, which are inconvenient to move, one worker often cannot finish the work of helping the side.

Disclosure of Invention

The invention aims to disclose a mattress capable of rising from the left side or the right side, and for the aspects of beauty treatment, massage and physical therapy, particularly for people who need nursing and are inconvenient to move, when the people need to turn on one's side to solve the problems of back changing position and changing clothes and trousers on one's side or changing bed sheets on one's side, the invention provides a worker or a user (when adopting an electric type) who operates a control handle rod to the left side with one hand, the control handle rod drives a left square lock column connecting seat and a right square lock column connecting seat at the moment, the left square lock column and the right square lock column connecting seat are inwards at the same time to drive a left square lock column to leave the upper part of a left round lock column of a main mattress assembly, and simultaneously the control handle rod drives a sliding rail anti-misoperation plate, so that the sliding rail anti-misoperation plate exposes out of a square rotary operating head of a telescopic cross universal joint of a hand jack, and the, A square rotary operating head sleeved in the telescopic cross universal joint rotates the telescopic cross universal joint, and the telescopic cross universal joint rotates to drive the hand-operated jack; when the hand-operated jack is lifted upwards, the main mattress assembly can easily and quickly obtain the function of lifting the left side to lean on the side safely according to the requirements of workers within 10 seconds; if the main mattress assembly needs to return to the original plane position from the side, the square rotary operating head of the telescopic cross universal joint is reversely rotated by the rotary handle, and the telescopic cross universal joint reversely rotates to drive the hand-operated jack; the hand-operated jack can descend downwards at the moment, and within 10 seconds, the main mattress assembly can easily and quickly obtain the function of turning from the side position to the original plane position according to the requirements of workers safely; the rotary handle of the square rotary operating head is taken out again, the control handle rod is pulled to the right direction to return to the original position, at the moment, the square lock column is locked above the round lock column under the action of leftward movement return of the left square lock column connecting seat and the right square lock column connecting seat, the main mattress assembly and the shell assembly are connected into a whole, meanwhile, the square rotary operating head of the telescopic cross universal joint of the hand-operated jack is blocked by return of the sliding rail misoperation preventing plate, and the safety effect of misoperation prevention is achieved.
