Description
Technical field
The present invention relates to medical instruments field, especially a kind of hydraulic regulation bed capable of nursing and supporting patient.
Background technology
Care bed is the sick bed that action inconvenient patient uses when being in hospital or nursing at home, and main purpose is easy for protecting
Reason personnel are looked after, and are easy to patients ' recovery.With a variety of demand of continuous development and market of science and technology, care bed is generally divided into
Electric care bed and Manual care bed.By the constantly improve of the regulation to care bed, and function, convenient shield can not only be realized
Reason, moreover it is possible to which the functions such as a variety of nursing amusements are provided.
At present, the Manual care bed of market only enters wardrobe in operation by the operation handle being arranged under care bed bed
Portion position lifts, and its operation is more laborious, moreover, operating mechanism service life is short.For electric care bed, its is simple to operate,
Position lifting can be achieved with using button, still, motorized adjustment needs each element gear and chain interoperation, and its stationarity is poor,
Driving dynamics is smaller.Moreover, patient prevents stasis from becoming silted up when the time of lying up is longer, it is necessary to stir body
Product, cause exanthemv, and majority is turned over by the way of artificial, it operates inconvenience.
To sum up, it is necessary to design it is a kind of turn over it is easy to operate, using stable hydraulic regulation bed capable of nursing and supporting patient.
The content of the invention
It is an object of the invention to provide a kind of hydraulic regulation bed capable of nursing and supporting patient, mainly solves to grasp present in prior art
Make the problems such as laborious, stationarity is poor, driving dynamics is smaller.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of hydraulic regulation bed capable of nursing and supporting patient, including bedstead, four supporting legs of bedstead bottom are arranged on, are arranged on bedstead
Bodyboard, be arranged on bedstead, two handrails for ballistic support, the pedal being arranged between the supporting leg of bedstead rear portion two, if
The fixed plate in four bedstead bottom, connection supporting legs is put, the battery being arranged on pedal, is arranged on bedstead rear portion controller,
And it is arranged on bedstead bottom, for nursing the hydraulic regulating device turned over.
Specifically, bodyboard includes interconnecting and being placed on the left bodyboard on bedstead and right bodyboard.
Further, hydraulic regulating device includes being arranged on pedal and the oil groove of built-in hydraulic oil, be arranged in oil groove,
For the liquid level sensor of level sensing, the oil pump being arranged at the top of oil groove, fuel pump outlet is arranged on, for preventing from carrying pressure
Hydraulic oil backflow non-return valve, the outlet valve being connected with non-return valve, be connected with outlet valve and be arranged on the combination at the top of oil groove
Valve, it is connected with combination valve, is arranged on fixed front edge of board and for the first beam hanger of left bodyboard adjustment, be connected, set with combination valve
The second beam hanger in fixed plate, for the adjustment of right bodyboard is put, and is connected respectively with combination valve, the first beam hanger and the second beam hanger
Pipeline.Controller is connected with liquid level sensor, combination valve and oil pump respectively.
Further, combination valve is connected and exported the dibit four-way electromagnetic commutation being connected with oil groove including import with outlet valve
Valve, and be connected respectively with dibit four-way electromagnetic reversing valve, for control first beam hanger and the second beam hanger respectively first
Solenoid directional control valve in solenoid directional control valve and the two or three six logical runback in three six logical runbacks.
Preferably, oil pump uses DC motor Driver.
Further, the first beam hanger and the second beam hanger include lower oil gun A and upper oil gun B.
Further, solenoid directional control valve and the two or three six in dibit four-way electromagnetic reversing valve, the one or three six logical runbacks
Solenoid directional control valve is driven using 4-20mA electric currents in logical runback.
Further, combination valve is connected and exported the dibit four-way electromagnetic commutation being connected with oil groove including import with outlet valve
Valve, and be connected respectively with dibit four-way electromagnetic reversing valve, for control the first beam hanger and the second beam hanger respectively the one or three
Solenoid directional control valve in solenoid directional control valve and the two or three six logical runback in six logical runbacks.
Compared with prior art, the invention has the advantages that：
(1) present invention is by setting patient or so turns in fixed plate the first beam hanger and the second beam hanger, due to hydraulic pressure
The compression volume of oil is smaller, is in course of adjustment more steady, the problems such as preventing mechanical structure bite.The device passes through direct current oil
The mode that pump is suppressed, its operation is more convenient, and its hydraulic pressure support power is bigger, ensures the support stress of care bed.Moreover, compared with machine
Tool is driven regulative mode, and more steady using hydraulic regulation, service life is longer.
(2) present invention is reasonably provided with non-return valve in the outlet of oil pump, during regulation, can effectively prevent from suppressing back
The problem of stream, the hydraulic oil with pressure is smoothly entered in beam hanger, moreover, in pump start, pressure and not will be carried
Hydraulic oil part isolation with pressure, reaches oil pump no-load starting, reduces energy loss.
(3) moreover, the ingenious setting combination valve of the present invention, switched by the direction of hydraulic oil, realize the lifting of beam hanger,
I.e. the cooperation of solenoid directional control valve is used for the liter for controlling the first beam hanger in dibit four-way electromagnetic reversing valve and the one or three six logical runback
The cooperation of solenoid directional control valve is used for the liter for controlling the second beam hanger in drop, dibit four-way electromagnetic reversing valve and the two or three six logical runback
Drop.Wherein, solenoid directional control valve is in runback in solenoid directional control valve and the two or three six logical runback in the one or three six logical runback
Type, consequently, it is possible in shut-down operation, ensure that hydraulic oil blocks, prevent nursing bed mattress from declining automatically.
(4) present invention is using electromagnetism in 4-20mA electric currents driving dibit four-way electromagnetic reversing valve, the one or three six logical runbacks
Solenoid directional control valve in reversal valve and the two or three six logical runback, realizes care bed head and side locations adjustment, its control mode
Simply, descending operation only can be achieved by inputting button, moreover, hydraulic regulation precision is higher, in lifting process, is not present
Jam or jitter phenomenon, make operating process more steady.
(5) the characteristics of present invention dexterously compresses small volume using hydraulic oil, and driving force is strong, with reference to dibit four-way electromagnetic
The commutation of solenoid directional control valve acts in solenoid directional control valve, the two or three six logical runbacks in reversal valve, the one or three six logical runbacks, changes
Become the flow direction of hydraulic oil, so as to realize the steady lifting of beam hanger, moreover, by setting battery, beaten using direct current generator
The mode of pressure, you can satisfaction is adjusted whenever and wherever possible.The simple in construction, simple operation of the present invention, regulation are steady, service life
Long, the advantages that adjusting whenever and wherever possible, compared with prior art, hence it is evident that there are prominent substantive distinguishing features and significant progressive,
Medical instruments field has very high practical value and promotional value.
