Automatic turnover bed

Abstract

The invention relates to an automatic turnover bed which comprises bed surfaces, rotating shafts, conveyor belts and a supporting rod, wherein the conveyor belts are arranged on the bed surfaces, anda human body can be turned through the translation of the conveyor belts; one rotating shaft is respectively arranged at the outer side of each bed surface, and a friction pulley is arranged on each rotating shaft; two fixed shafts are arranged at the inner side of each bed surface, and a bearing and a roller are arranged on each fixed shaft; a plurality of short conveyor belts are sleeved on therollers and the friction pulleys; the middle parts of the two bed surfaces are connected together through a hinge, and a gap exists; the lower surfaces of the two fixed shafts at the inner side of the bed surface are connected with the supporting rod, and the lower surface of the supporting rod is connected with a sliding nut; the sliding nut is installed on a guide screw with left-handed and right-handed threads; the bed surfaces can descend to form a V shape or ascend through the open and close movement of the sliding nut; and when the bed surfaces ascend or descend, the two rotating shaftsat the outer side can horizontally slide in a slotted hole.

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
