Description
Technical field
The present invention relates to a kind of ophthalmology optometry auxiliary facilities, particularly a kind of combination optometry table.
Background technology
The major function of combination optometry table is for poor sight patient provides comfortable inspection and optometry environment, and provides necessary locus and power supply support for using combining of multiple instrument in examination of visual acuity and optometry.This series products of combination optometry table is brought into use in optometry and ophthalmic medical industry at present, and become gradually the indispensable auxiliary facilities of this industry, the equipment that it uses many optometrys combines, supporting comfortable multifunction seat of while, this has not only strengthened the efficiency of check and the degree of accuracy of check, also allows patient in environment, carry out refraction examination easily.Exactly because its practicality and efficient, optician's shop and ophthalmologic hospital that it has started are at home and abroad popularized.Market at home only, more than annual requirement just reaches ten thousand covers.On vast foreign market, demand is more.The product of some imports, price easily seven or eight ten thousand, upper 100,000, and domestic poor product, but quality can not be guaranteed.On the other hand, market existing combination optometry table complicated operation, locates loaded down with trivial detailsly, uses very inconvenient.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provide a kind of structure more reasonable, locate combination optometry table simple, easy to use.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of combination optometry table, comprises seat and optometry table, on the base of optometry table, is fixed with column; Be characterized in: on column, be connected with some rocking arms, on the support of optometry table, be fixed with fixed arm, on fixed arm, be also connected with rocking arm;
Described rocking arm comprises handle, and handle is fixed on universal drive shaft, and the front end of universal drive shaft is connected on fixed block by the first wire rod thread, and rear end is fixed on connecting rod, and connecting rod is fixed on Universal pipe, and Universal pipe is connected on contiguous block by the second wire rod thread; The first screw mandrel and the second screw mandrel are positive and reverse return screw mandrel; Pole is also installed on fixed block, instrument fixed support is installed on pole, contiguous block is socketed on column or fixed arm by collar bush; The screwed hole that connects the first screw mandrel on fixed block leads to the pole in fixed block, and the screwed hole that connects the second screw mandrel on contiguous block leads to the collar bush in contiguous block;
Between contiguous block and fixed block, be also connected with screw rod, be arranged with spring and sleeve on screw rod, the rear end of spring is fixed on sleeve, on the screw rod of spring at front end, is provided with adjusting nut;
Be connected to the fixed bar on fixed block being also provided with front end above universal drive shaft, the rearward end of fixed bar is provided with skewback, skewback is provided with regulating tank and cam path, the bottom of skewback is provided with through regulating tank, cam path and passes the set screw of skewback, the rearward end of universal drive shaft is stretched out from cam path, and the rear side part of universal drive shaft is tabular and forms cam mechanism with skewback.
In above-described combination optometry table: can also be covered with shell body on rocking arm.On column, can be provided with some rocking arm installing holes, like this, can install by height as required.
Main inventive point of the present invention is the structure of rocking arm.The seat relating in the present invention and optometry table can be disclosed any seat of the present invention and optometry table of being adapted in prior art.Seat can by two cover electric pushrods be power source with realize chair rise and fall and vertical lie stretched out flat.Headrest position also adopts adjustable design, can on the four direction of upper and lower front and back, carry out adjusting in a big way.Armrests can adopt current state-of-the-art interlock lifting, can raise and reduce with setting level along with the upright of the chair back.On the housing of optometry table, can be furnished with the charging jack by instrument charging use to corresponding optometry, control panel can be equipped with in the top of housing, by this control panel, lifting, pitching and the key that can control chair reset, can also control the adjusting of switch and the lamplight brightness of illuminator lamp, meanwhile, can also control the adjusting of indirect electric power output voltage and the power supply of external optometry equipment controls.
In the present invention, rocking arm can arrange 2-4 cover, and every cover rocking arm can be fixed a kind of optometry or inspection instrument, a few cover rocking arm synergism, thus realized degree of accuracy and the integrity of prescription.
In the present invention; the position adjustments of rocking arm is achieved in that this action of pulling by handle; can realize the spin locking at each position of rocking arm and the locking of rocking arm up-down adjustment; make doctor or optometrist easily optometry equipment be adjusted to needed position (patient is at the moment), thus avoided that the operation of a plurality of actions brings loaded down with trivial details and inconvenient.Specifically: when pulling handle with hands, it can drive universal drive shaft rotation, like this, can moment of torsion be passed to the first screw mandrel, connecting rod simultaneously, and the principle of utilizing cam mechanism makes skewback generation strain, connecting rod passes to the second screw mandrel by moment of torsion by Universal pipe, and the first screw mandrel and the second screw mandrel are positive and reverse return screw mandrel.Therefore, when handle rotates, the first screw mandrel and the second screw mandrel can screw in simultaneously or screw out, and when screw mandrel screws in, can head into pole or collar bush, thereby realize locking action, when screw mandrel screws out, can realize and unclamp action.Therefore when handle rotates, will form action locked or that discharge to the fixed block at these structure two ends and contiguous block, thereby realize the rotation location of two ends parts.In addition, the rear side part of universal drive shaft is tabular (local is column) and forms cam mechanism with skewback, when cam mechanism deforms by skewback, also can produce to fixed bar the action of locking or release, in conjunction with parts such as springs, the up-down adjustment location of having realized left end parts, the instrument or the work top that are fixed on fixed block will be positioned in desired position.
From above structure explanation, can find out, when doctor or optometrist are contained in optometry equipment on the instrument fixing rack of the rocking arm described in this present invention, as long as pull handle, loosen location, instrument can be adjusted to patient at the moment like a cork, mix up behind position, also as long as spanner is pulled to opposite direction, like this with regard to locked location, the position that instrument will very firmly be fixed on patient at the moment easily or doctor and optometrist are wanted.
Compared with prior art, the present invention is rational in infrastructure, and it has saved the too much operation in optometry process, by its simplified control, is that a step completes, and makes optometry equipment fixedly becoming simply and easy operating in face of patient.And adopt mechanical fixing, not only safe but also durable, failure rate is low, practical, locking quick and precisely, settles at one go.
