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, and a 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 the rollers 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 shafts at the outer side can horizontally slide in a slotted hole.

Description

Automatic turnover bed

Affiliated technical field

The present invention relates to a kind of multi-functional bed, especially a kind of bed that can stand up automatically.

Background technology

At present, three used bending machines can only let patient sit up or lift lower limb and can not stand up in the known hospital, and the long-term pressurized of patient's back and buttocks is prone to give birth to decubital ulcer.The automatic turnover bed patent of Japanese's application January 22 in 2002 (application number: 02114415.X publication number: CN1372875A) in trial-production, find following problem:

1. as shown in Figure 7 flexible material 15 is big monoblock canvas, after receiving human body gravity, will produce local elongation and serious plastic deformation in the middle of inevitably, causes at last can't using at all.

As shown in Figure 8 the effect of locking plate 16 be for bed surface recessed come or support flat; But because of the distortion of flexible material 15, the difference of human body weight, the needed coupling mechanism force of factors such as wearing and tearing of machine components is different; And constantly change, so be difficult to confirm the size of required coupling mechanism force.Be very easy to again during work skid, the locking situation is extremely unreliable, usually occurs loosening.

Summary of the invention

Distortion and the easy problem of slip of locking plate stretch for the flexible material of automatic turnover bed more than solving (02114415.X) is easy; The invention provides the automatic turnover bed of a kind of brand new; This stands up bed and has not only solved the yielding problem of flexible material; And fundamentally changed the recessed operation principle of putting down of bed surface with support, make duty highly stable, reliable.

The present invention solves the technical scheme that its technical problem takes: about bed surface is designed to two, conveyer belt is arranged on the bed surface, and the translation of conveyer belt can make human body reversal; There is a rotating shaft in the outside of every bed surface, and friction pulley is arranged on the rotating shaft; There are two fixed axis the inboard of bed surface, and bearing and cylinder are arranged on the fixed axis; Overlapping a plurality of very short and small conveyer belts on cylinder and the friction pulley; The centre of two bed surfaces connects together with hinge, and gapped; Following and the support bar of two fixed axis that bed surface is inboard is connected the following sliding nut that connecting of support bar; Sliding nut is contained on the screw mandrel of left-handed and right-handed thread; The open and close movement of sliding nut can make bed surface decline forming V-shape or rise; When rising or descending, two rotating shafts in the outside can horizontal slip in slotted hole.

The invention has the beneficial effects as follows, owing to adopted a plurality of very short and small conveyer belts, so the distortion of conveyer belt only in elastic range, can not produce plastic deformation.Because the up-down of bed surface is to lean on bar to support, and the effect of vertical support is very reliable, it is loosening to skid again.

Specific embodiments

In Fig. 1, two bed surfaces 11 forming V-shape that can descend, moving of conveyer belt 5 can make human body 3 stand up; The top friction pulley 4 that overlapping of rotating shaft 1; The top bearing 7 that all is equipped with of fixed axis 6 is equipped with cylinder 8 on the bearing 7, conveyer belt 5 be enclosed within cylinder 8 and friction pulley 4 above; Rotating shaft 1 rotation is moved conveyer belt 5, and human body 3 is upset in the opposite direction just.In Fig. 2, when the middle decline forming V-shape of bed surface 11,1 on 2 rotating shafts on the bed surface 11 slide in slotted hole 9 inwards.In Fig. 3, bed surface 11 again can be flat by support, and 2 rotating shafts 3 that support on the bed surface 11 at ordinary times outwards slide again, and the centre of two bed surfaces 11 connects together with hinge, and gapped f.2 sliding nuts 13 among Fig. 4 and Fig. 5 be contained in left and right sides rotation direction leading screw 14 above, the open and close movement meeting of sliding nut 13 drives support bar 12 and bed surface 11 is risen or falls when leading screw 14 rotation.In Fig. 6, whole bed surface 11 is made up of a plurality of conveyer belts 5.
