Abstract

The utility model discloses a dual-lifting mechanism of a hospital bed, which comprises a bed frame and a base frame, wherein a pair of lifting mechanisms formed by sliding blocks, long rods, short rods, pushing rods, telescopic motors, bed frame supporting bases and motor fixing bases are arranged between the bed frame and the base frame, and achieves the purpose of timely regulating the height of the hospital bed, and the pair of lifting mechanisms can be matched with each other to use and realize the functions of an oblique bed surface owing to the height difference, so as to satisfy various use demands.

Description

Sick bed two elevator structure

Technical field

This utility model belongs to medical instruments field, specifically a kind of sick bed two elevator structure.

Background technology

At present, the sick bed that uses in hospital can only be had a rest for patient's recumbency, and this sick bed has solved patient and lain and the problem of sitting.As medical personnel, patient is checked or when treating or shifting, because bed surface is fixed on the certain level height and position all the time, can not according to medical personnel's actual medical and the in good time adjustment bed surface height of nursery work situation, many troubles have been brought to routine work.

Patent documentation CN102038589A discloses a kind of elevating mechanism for nursing bed, comprises bedstead, two supporting legs and two linking arms, is provided for the adjusting device of lifting bedstead between bedstead and supporting leg.Adjusting device directly is arranged on the supporting leg with roller, when carrying out the lift adjustment of bedstead, is limited by unavoidably the impact of supporting leg self structure, causes the adjusting device assembling unreasonable, produces and regulates situation not in place, inconvenient operation.

The utility model content

The problem that exists in order to solve prior art, this utility model provides the elevating mechanism of a kind of automatic adjusting bed face level height position.

In order to realize above purpose, the technical solution of the utility model is as follows: a kind of sick bed two elevator structure, comprise bedstead and underframe, a pair of elevating mechanism that is made of slide block, stock, quarter butt, push rod, flexible motor, bedstead supporting seat and motor fixing seat is set between bedstead and underframe; Described bedstead arranges bedstead supporting seat and motor fixing seat, and underframe arranges slide block; The hinged stock of described slide block, stock is fixedly connected with quarter butt and both form angle, the hinged bedstead supporting seat in this angle, the push rod of quarter butt articulated telescopic motor, the bottom-hinged motor fixing seat of flexible motor.

Further, described underframe arranges a bearing, the bearing hinged support rod, and the stock in strut and one of them elevating mechanism is hinged.

Described a pair of elevating mechanism is respectively as head of a bed elevating mechanism and tailstock elevating mechanism, and their angles of inclination separately reach ± and 14 °.

The built-in bed of described elevating mechanism end illuminating lamp.

Described elevating mechanism internal battery, control box, deconcentrator and electric wire.

Compared with prior art, owing to being provided with elevating mechanism, realize adjusting the function of berth height in good time.Simultaneously, the two elevator structure of the head of a bed and tailstock, under poor being used in conjunction with of both differing heights, the bed surface that can tilt satisfies various Special use demands.

The specific embodiment

As shown in Figure 1, the underframe 13 of sick bed is provided with two symmetrical elevating mechanisms, and the two elevator structure supports bedstead 1, it is risen overally or descend or tilt.Two elevating mechanisms are respectively head of a bed elevating mechanism 2 and tailstock elevating mechanism 3.

Now take head of a bed elevating mechanism as example, describe the formation of elevating mechanism: underframe 13 arranges slide block 10, and the hinged stock 9 of the moving fulcrum D of slide block 10, stock 9 are fixedly connected with quarter butt 8 and intersect at the C point and be integrally formed.The push rod 7 of the moving fulcrum B articulated telescopic motor 5 of quarter butt 8, the fixed pivot A of the bottom-hinged motor fixing seat 6 of flexible motor 5, the upper end of motor fixing seat 6 is fixed at the F of bedstead 1 point place.Bedstead supporting seat 4 upper ends are fixed at the E of bedstead 1 point place, the intersection point C of the bedstead supporting seat 4 hinged quarter butts 8 in lower end and stock 9.

Sick bed produces lifting and tilting action under the effect of two elevator structure, the groundwork process of single elevating mechanism is as follows: flexible electric motor starting and when driving the push rod elongation, quarter butt and stock are rotated counterclockwise around the C point, slide block moves right, at this moment, the C point rises, and promotes the bedstead supporting seat and moves vertically upward; Otherwise the bedstead supporting seat moves vertically downward.

On the basis of above-mentioned groundwork process, produce bedstead and rise overally or descend when two elevating mechanism synchronization actions; When the action of one of them elevating mechanism and another elevating mechanism is failure to actuate or produce bedstead when carrying out reverse action tilts towards the head of a bed or tailstock, the angle of inclination reaches ± and 14 °, magnitude of inclination is large.

In order to prevent that two elevating mechanisms from the vertically non-play of controlling occuring each other, to control the relative position of bedstead and underframe, an elevating mechanism arranges strut therein.Specifically, first at underframe 13, a hold-down support 11 is set, at an end of the hinged strut 12 of the fixed pivot H of hold-down support 11, then selects the other end of a moving fulcrum G hinged support rod 12 of stock 9.The operation principle of strut is:

1, when two lift telescopic motors are not worked, become fixed triangle shape by D, G, 3 of H, prevent two D point displacements;

2, when the bedstead horizontal lifting, because the H point is fixing, C point when lifting, owing to G point being arranged as pivot point, the D point can only be corresponding to the right be moved to the left, and C, D two places move and are consistent in two elevating mechanisms;

3, when the flexible motor of head of a bed elevating mechanism static, when tailstock elevating mechanism motor shortened, bedstead was done corresponding turning clockwise around G point, the D point of head of a bed elevating mechanism is past to be moved left, and moves right and the D of tailstock elevating mechanism point is past, completes the tailstock tilt function;

4, when the flexible motor of tailstock elevating mechanism static, when head of a bed elevating mechanism motor shortened, a bed body was done corresponding being rotated counterclockwise around G point, the D point of head of a bed elevating mechanism is past to be moved left, the D point of tailstock elevating mechanism is past to move right, and completes the tailstock tilt function.
