Abstract
The utility model relates to an automatic optometry instrument, which comprises a left test body and a right test body respectively in symmetrical arrangement, wherein each test body comprises a bearing plate, a control circuit, a rotating shaft, a plurality of lens turntables, a plurality of test lenses and a plurality of first motors, the control circuit and the rotating shaft are arranged on the bearing plate, the lens turntables are arranged on the rotating shaft, the test lenses are circumferentially distributed on each lens turntable, the first motors are used for connecting each lens turntable and driving each lens turntable to rotate, each lens turntable comprises a plurality of main lens turntables and a plurality of auxiliary lens turntables, a crack sheet is arranged on at least one auxiliary lens turntable, and each test body also comprises a second motor used for connecting the crack sheet and driving the crack sheet to rotate. The automatic optometry instrument has the advantages that the crack sheet is fixedly arranged on an auxiliary lens rotating wheel, and the second motor is controlled through regulating a knob, so the rotating angle of the crack sheet is changed for determining the astigmatism shaft position, the repeated lens replacement is not needed during the testing, more convenience is realized, and in addition, the auxiliary driving motor adopts a subdivided step moor, so the test data is more accurate.
Description
Technical field
This utility model relates to the examination equipment for eye field, particularly a kind of auto-refractomer.
Background technology
The principle of optometry is an inspection light incident retrobulbar gathering situation, is standard with the emmetropia state, measures to be examined and gathers the different degree of scattered error between eye and emmetropia.Promptly make output as the comprehensive optometry appearance of one of eye refractometer, lens or post mirror are packed in the runner system,, change eyeglass more effectively, more quickly, reach the purpose of optometry through simple knob according to the principle of above-mentioned optometry; Simultaneously, the inner eyeglass of eye refractometer is in closed state, is difficult for making dirty.The comprehensive optometry appearance generally is made up of strength somascope, projector and optometry compound table three parts, adopts runner system to realize various optometry operations mostly.For low vision patient, the inspection of axis of astigmatism is a relatively more crucial problem.At present, the main method that is used to detect axis of astigmatism has subjective method of inspection and objective method of inspection.Objective method of inspection comprises computerized optometry, inspection shadow.Subjective method of inspection comprises comprehensive optometry appearance and inserted sheet optometry.Normally adopt the crack sheet, astigmatic chart, crossed cylinders, pinhole disk, honeycomb sighting target are confirmed axis of astigmatism and astigmatism, but ten minutes bothers because eyeglass varies, and operate and have relatively high expectations, and are difficult to accurately detect astigmatism and axis of astigmatism.
The utility model content
The main purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, proposes a kind of auto-refractomer that can accurately detect axis of astigmatism.
This utility model adopts following technical scheme:
A kind of auto-refractomer; Comprise symmetrically arranged left and right test body respectively; Each test body comprises support plate; Be arranged at control circuit and rotating shaft on the support plate, be arranged at several lens slewing discs, the some testing lens of circle distribution on each lens slewing disc and some first motors that connect each lens slewing disc independent rotation of driving in the rotating shaft, it is characterized in that: said lens slewing disc comprises some primary mirror sheet rotating disks and some auxiliary lens rotating disks; At least one auxiliary lens rotating disk is provided with the crack sheet, also includes to connect to drive second motor that this crack sheet rotates.
According to this utility model one preferred embodiments; Said auxiliary lens rotating disk is provided with crack sheet mount pad; This mount pad is formed with outer gear rim; Cooperate this mount pad outer rim to be provided with driving gear in the said rotating shaft, this driving gear drives said mount pad by said second motor-driven and said crack sheet rotates.
According to this utility model one preferred embodiments, also include and control the knob that said second motor is controlled crack sheet rotational angle.
Can know by above-mentioned description this utility model; Compared with prior art, the utlity model has following beneficial effect: the auto-refractomer of this utility model is fixedly set in the crack sheet on the auxiliary lens runner; Thereby control second motor rotation change crack sheet rotational angle through adjusting knob and confirm axis of astigmatism; Do not need multiple replacing eyeglass during test, more convenient and second motor adopts segmentation cloth to advance motor, makes test data more accurate.

Fig. 2 is the inner turntable structure sketch map of the test body of this utility model.
The specific embodiment
Below this utility model is done further to describe through the specific embodiment.
With reference to Fig. 1, Fig. 2, a kind of auto-refractomer comprises symmetrically arranged left and right test body respectively; Each test body 1 comprises support plate; Be arranged at control circuit and rotating shaft 2 on the support plate, be arranged at two primary mirror sheet rotating disks 3 and two auxiliary lens rotating disks 4 in the rotating shaft 2, the some testing lens of circle distribution on each lens slewing disc and four first motor 3a that connect each lens slewing disc independent rotation of driving; Wherein an auxiliary lens rotating disk is provided with crack sheet 5; This correspondence auxiliary lens rotating disk is provided with has crack sheet mount pad 6, and this mount pad 6 is formed with outer gear rim, cooperates these mount pad 6 outer rims to be provided with driving gear 7 in the rotating shaft 2; Drive driving gear 8 rotations through the second motor 3b and drive mount pad 6 and 5 rotations of crack sheet, this second motor 3b adopts the segmentation motor.Also include and control the knob 9 that the second motor 3b controls crack sheet 5 rotational angles; Adopt the comprehensive optometry appearance of this utility model to comprise also that usually being used to control this comprehensive optometry appearance realizes various optometry function operations panels; Operation control panel comprises touch screen, and correspondence is provided with crack sheet function sighting target on the touch screen.
During use; Crack sheet function sighting target on operator's touch operation panel carries out the axis of astigmatism test, tests intravital auxiliary lens rotating disk action and makes the crack sheet be in the form position, and the measured sees through form and carries out observation test; The while tester is turning knob independently; After observed test sighting target reached optimum state through the crack sheet, at this moment, the operator can read the judgement of related data as axis of astigmatism.
The above-mentioned specific embodiment that is merely this utility model, but the design concept of this utility model is not limited thereto allly utilizes this design that this utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading this utility model protection domain.
