Abstract
A hand-operated integrated refractometer comprises a cross rack for regulating pupil distance, a top frame and fine-turning members. The cross rack for regulating pupil distance comprises a cross rack casing, independent pupil distance regulators are symmetrically arranged on the cross rack casing bilaterally. Each pupil distance regulator comprises a guide rail block horizontally arranged on thecross rack casing, sliders slidably connected with the guide rail blocks is arranged below the guide rail blocks, and a crankshafts are connected to the sliders and provided with lead-screw sliders. A lead-screw support block is fixed on the cross rack casing and supports lead-screws arranged horizontally, the lead-screw sliders are connected to the lead screws in a threaded manner, and pupil distance hand wheels are connected to the outer ends of the lead-screws. Scale sign plates are fixed on the sliders, and scale indicating plates fixed on the cross rack casing are arranged below the scale sign plates. By the pupil distance regulators arranged independently bilaterally, the pupil distance can be regulated more flexibly and conveniently under single action, the measurement results are more accurate, and actual requirements of people subjected to vision measurement can be met better.
Description
Technical field
The present invention relates to a kind of optometry equipment, particularly a kind of manual comprehensive optometry instrument.
Background technology
Manual comprehensive optometry instrument of the prior art comprises the upper frame for suspention optometry dish; Be used for to regulate and the fixing fixedly hands wheel of optometry dish position; The horizontal labelling that shows optometry dish horizontal tilt state; Be used for regulating the horizontal hands wheel of window and tested eyes horizontal level; The interpupillary distance hands wheel that is used for the relative position of adjusting window and tested pupil of both eyes; Be used for the different auxiliary examination eyeglass of conversion; Finish the auxilliary sheet hands wheel of multiple visual function evaluation; Be used for measuring the interpupillary distance adjusting crossbearer of interpupillary distance; Be used for the axle position of measuring and adjusting astigmatism and the crossed cylinder lens part of angle; In auxiliary lens and cylindrical lens are arranged, be used for to regulate and measure the lung head of myopia and astigmatism; Be used for regulating and measuring the component prism of stravismus; And the post mirror axle position handwheel that is used for adjusting cylindrical lens axle position.
The comprehensive optometry instrument is as a kind of ophthalmology optometry apparatus, main effect is exactly optometry, how to guarantee that the measured is comfortable, test easily, and how to allow optometrist by simply, optometry is carried out in operation efficiently, is the whether important criterion of success of product.Measurement for interpupillary distance, but no matter what be that manual comprehensive optometry instrument domestic or import all takes is integrally-regulated structure, though the velocity ratio that this structure is regulated is very fast, but this does not also meet the human body practical situation, on interpupillary distance is regulated, all can only realize the symmetry adjusting, can only walk simultaneously on both sides when namely regulating interpupillary distance.Though most of mankind's eyes are all with respect to bridge of the nose symmetry, but not all people is, so though the structure of walking simultaneously in both sides can be adjusted interpupillary distance more fast, but concerning pupil not with respect to the crowd of bridge of the nose symmetry, the eyes that this measurement interpupillary distance is worn later can make eyes feel tired, uncomfortable.This is comprehensive optometry instrument problem demanding prompt solution, also is the technological difficulties that this project directly faces.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, a kind of reasonable in design is provided, effectively improves the manual comprehensive optometry instrument of optometry effect.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of manual comprehensive optometry instrument, comprise interpupillary distance adjusting crossbearer, upper frame and lung head, lung head, upper frame are connected interpupillary distance and regulate on the crossbearer, are characterized in: described interpupillary distance is regulated crossbearer and is comprised the crossbearer housing, and left-right symmetric is provided with independently interpupillary distance actuator on the crossbearer housing; Described interpupillary distance actuator comprises the way block that is horizontally set on the crossbearer housing, is provided with the slide block that is slidingly connected with way block below way block, is connected with bent axle on the slide block, and bent axle is provided with the screw mandrel slide block; Also be fixed with the screw mandrel back-up block on the crossbearer housing, screw mandrel back-up block upper support has horizontally disposed screw mandrel, the screw mandrel slide block is threaded on the screw mandrel, is provided with the interpupillary distance handwheel that connects by the screw mandrel fixed block in the outer end of screw mandrel, and the screw mandrel fixed block also is fixed on the crossbearer housing; At slide block the scale label is arranged fixedly, be located at the calibration indicator sign board that is fixed on the crossbearer housing below the scale label.
In the above-described manual comprehensive optometry instrument technical scheme: on the crossbearer housing, can also be provided with shell, be provided with interpupillary distance at the shell with scale label corresponding position and measure viewport.
The operational approach of the manual comprehensive optometry instrument of the present invention is: when measuring interpupillary distance, regulate left and right sides interpupillary distance handwheel respectively according to measured's actual interpupillary distance, the interpupillary distance handwheel drives screw mandrel, makes screw mandrel rotating band movable slider and scale label move left and right; By calibration indicator sign board indication reading, when reaching the measuring position, read left and right sides interpupillary distance size respectively, actual interpupillary distance be of a size of left and right sides interpupillary distance size reading and.
Compared with prior art, the manual comprehensive optometry instrument of the present invention adopts left-right symmetric to be provided with the independently mode of interpupillary distance actuator, make the adjusting of interpupillary distance realize the single action adjusting, more flexible when regulating interpupillary distance, measurement result is more accurate, more meet tested crowd's actual demand, and can't make the complex operation difficulty, integrally-regulated basic identical with before.
