Description

A kind of lifting bed that relies on gravity to regulate

Affiliated technical field:

This utility model relates to a kind of lifting bed, exactly is a kind of lifting bed that relies on gravity to regulate that patients uses.

Background technology:

Traditional lifting bed is a hand-rail type lifting bed.By the lifting of nursing staff's hand shaken, thereby use inconvenient.Chinese patent ZL95101034 has disclosed a kind of " automatically controlled lifting bed ", comprise mattress, lifting button, lifting support, elevating bracket, lifting shaft, bedstead, connecting rod, lifting shaft, support, both sides at mattress are equipped with lifting button, the input that the motor motor is installed on support is provided with control circuit, the outfan of motor is a worm screw, and worm screw is connected with lifting shaft through worm gear.Adopt such scheme, easy to use, the patient sleeps and just can alleviate nursing staff's workload from line operate in bed.But such scheme also comes with some shortcomings: as complex structure, the cost costliness is unfavorable for that large tracts of land promotes the use of.

The utility model content:

In order to address the above problem, it is a kind of simple and practical that this utility model provides, and patient can rely on the lifting bed of gravity from main regulation.

The technical solution of the utility model is: a kind of lifting bed that relies on gravity to regulate, comprise bed board and bedstead, described bed board is formed by connecting by the two sub-bed boards in front and back, described back bed board is hinged by rocking bar and bedstead one side, preceding bed board one end is hinged with the back bed board, mid portion and bedstead opposite side are hinged, and the other end and a hydraulic stem are hinged, and the bottom of this hydraulic stem is fixed on the bedstead; Described hydraulic stem two ends respectively are provided with an oil pipe, and two oil pipes are communicated with by a valve.

Operation principle of the present utility model is to constitute a planar linkage mechanism by bed board and bedstead, is out of shape when bed board is subjected to downward pressure, and back bed board level is sunk, the preceding bed board state that becomes to be inclined upwardly, thus realize that patient relies on the purpose of gravity from main regulation.The effect of hydraulic stem is to control bed board distortion, and when tubing valve was closed, the hydraulic oil at the piston two ends of hydraulic stem was isolated by valve, can not flow, so hydraulic stem can keep certain-length, and bed board can't be out of shape, and is identical with general bed; When patient need sit up, as long as open tubing valve, the hydraulic oil of the piston upper end of hydraulic stem, owing to be subjected to the pressure of piston, thereby flow to by oil pipe in the inner chamber of piston lower end, cause piston to move to the top of hydraulic stem inner chamber always, bed board is the therefore distortion gradually along with the extension of hydraulic stem also, bed board sinking, preceding bed board become acclivitous state after forming at last, thereby realize the purpose that the help patient sits up.When needs return to level to bed board, as long as patient leans on after a little firmly, hydraulic stem pressurized retraction, the hydraulic oil of piston lower end are back to the piston upper end, and bed board is closed tubing valve during to level and got final product.

The beneficial effects of the utility model are: simple in structure, not by any power, only the gravity with patient just can independently be out of shape, easy to use, be suitable for hospital, family promotes the use of, can be action inconvenient people's bunk beds such as patient, old man and provide convenience, solve medical personnel simultaneously and cross operations such as low inconvenience is rescued, auscultation, blood drawing because of berth.

Description of drawings

Below in conjunction with the drawings and specific embodiments this utility model is described further:

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is this utility model user mode figure.

The specific embodiment

Referring to accompanying drawing 1, a kind of lifting bed that relies on gravity to regulate, comprise bed board 1 and bedstead 2, bed board 1 is formed by connecting by front and back two sub-bed board 1-a, 1-b, described back bed board 1-b is hinged by two rocking bars 3 and bedstead 2 one sides, and preceding bed board 1-a one end is hinged with back bed board 1-b, and mid portion and bedstead 2 are hinged, the other end and a hydraulic stem 4 are hinged, and the bottom of this hydraulic stem 4 is fixed on the bedstead 2; Hydraulic stem 4 two ends respectively are provided with oil pipe 5-1, a 5-2, and two oil pipe 5-1,5-2 are communicated with by a valve 6, and valve 6 is connected with a manual switch 8 by line, makes things convenient for patient and nursing staff to use.

When tubing valve 6 was closed, the hydraulic oil at hydraulic stem piston 7 two ends was isolated by valve 6, can not flow, so hydraulic stem 4 state that can remain retracted, bed board 1 can't be out of shape, identical with general bed; When patient need sit up, as long as open tubing valve 6, the hydraulic oil of hydraulic stem piston 7 upper ends, owing to be subjected to the pressure of piston 7, thereby flow to piston 7 lower ends, cause piston 7 to move to the inner chamber top of hydraulic stem 4 always by oil pipe 5-1,5-2, bed board 1 is the therefore distortion gradually along with the extension of hydraulic stem 4 also, bed board 1-b sinking, preceding bed board 1-a become acclivitous state after forming at last, and the angle of inclination can be adjusted arbitrarily as required, thereby realize the purpose that the help patient sits up.When needs return to level to bed board 1, as long as patient leans on after a little firmly, hydraulic stem 4 pressurizeds retraction, the hydraulic oil of piston 7 lower ends is back to piston 7 upper ends, and bed board 1 is closed tubing valve 6 during to level and is got final product.

Claims (2)

1. a lifting bed that relies on gravity to regulate comprises bed board (1) and bedstead (2), it is characterized in that described bed board (1) is formed by connecting by front and back two sub-bed boards (1-a, 1-b), and back bed board (1-b) is hinged by rocking bar (3) and bedstead (2) one sides; Preceding bed board (1-a) end is hinged with back bed board (1-b), and mid portion and bedstead (2) are hinged, and the other end and hydraulic stem (4) are hinged; The bottom of this hydraulic stem (4) is fixed on the bedstead (2), and hydraulic stem (4) two ends respectively are provided with an oil pipe (5-1,5-2), and oil pipe (5-1,5-2) is communicated with by tubing valve (6).

2. a kind of lifting bed that relies on gravity to regulate according to claim 1 is characterized in that tubing valve (6) is connected with hand switch (8) by line.
