automatic rollover bed

Abstract

A bed that can turn over automatically. It is composed of a bed surface, a rotating shaft, a conveyor belt and a support rod. There is a conveyor belt on the bed surface, and the translation of the conveyor belt can make the human body turn over; there is a rotating shaft on the outside of each bed surface, and there is a friction wheel on the rotating shaft; the inner side of the bed surface There are two fixed shafts, bearings and rollers on the fixed shafts; there are many very short conveyor belts on the rollers and friction wheels; the middle of the two bed surfaces is connected by hinges, and there is a gap; the inner side of the bed surface The bottom of the two fixed shafts is connected with the support rod, and the bottom of the support rod is connected with the sliding nut; the sliding nut is installed on the screw rod with left-handed and right-handed threads; the opening and closing movement of the sliding nut can make the bed surface drop into a V-shape or Rise up; when rising or falling, the two rotation shafts on the outside can slide horizontally in the long holes.

Description

Technical field [0001] The invention relates to a multifunctional bed, in particular to a bed that can turn over automatically. Background technique [0002] At present, the three-fold bed used in the known hospital can only allow the patient to sit up or lift his legs but cannot turn over. The patient's back and buttocks are under pressure for a long time, and bedsores are prone to occur. The patent (application number: 02114415.X publication number: CN1372875A) of the automatic turning bed that the Japanese applied for on January 22, 2002 found the following problems in the trial production: [0003] 1. If Figure 7 The flexible material 15 shown in is a large piece of canvas, which will inevitably produce local stretching and severe plastic deformation in the middle after being subjected to the gravity of the human body, and finally cause it to be unusable at all. [0004] 2. If Figure 8 The function of the locking disc 16 shown in is to dent or flatten the bed surface...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems that the flexible material of the automatic turning bed (02114415.X) is easy to be stretched and deformed and the locking plate is easy to slip, the present invention provides an automatic turning bed with a new structure, which not only solves the problem that the flexible material is easy to deform problems, and fundamentally changed the working principle of concave and flattening of the bed surface, making the working state very stable and reliable
