Description

It is a kind of to receive the anti-memory equipment for examining vision of function with storage

Technical field

It is specially a kind of to receive the anti-memory equipment for examining vision of function with storage the utility model relates to medical field.

Background technique

Visual chart is the chart for measuring eyesight.The visual chart that the country uses has: international standard visual chart, logarithm eyesight Table, Lan Shi ring visual chart.Functionally dividing has near vision test type, distant vision test chart.Visual chart is formulated according to the principle at visual angle.Inspection Have an eyesight test and be generally divided into two class of distant vision and near vision, distant vision mostly uses international standard visual chart, this table be 14 row sizes not It is formed with different " E " word of opening direction；Measurement is from 0.1-1.5 (or from 4.0-5.2)；Every row has label, the view of examinee Visual chart operating method line is parallel with 1.0 a line, apart from 5 meters of visual chart.

Patient's vision is checked commonly using visual chart in hospital or clinic, but due to the test letter in visual chart Often fixed, it is relatively good for some people's memory, these test alphabetic directions are remembered soon, will to test As a result there is deviation, influence diagnosis of the doctor to eye eyesight；It is all to need to be placed on desk additionally, due to most of visual charts On, without support frame, when placement, can be tilted, also will affect the observation of patient, furthermore, due to eye test in various physical examinations all It is that must look into item, in large-scale physical examination, the single side of visual chart designs meeting so that the physical examination time lengthens, due to depositing for the above problem , therefore visual chart must be improved.

Application No. is CN201420749878.0, disclosing one kind in the patent that publication date is 2015.04.29 can be rolled Dynamic visual chart, the utility model are made of eyesight watchcase, visual chart, roller, it is characterized in that: visual chart is attached to eyesight watchcase On interior roller, in use, user rotates roller for different testees, change visual chart sequence.The utility model Beneficial effect be: so that visual chart is played the role of itself, reply memory visual chart sequence measured, but due to rolling Cylinder surface is curved surface, can be impacted to tester's eye test result, in addition, since the visual chart in roller is in anti-memory side There is no good effects in face, because being put in order from top to bottom there is no changing, moreover, the visual chart is since length is shorter, It must be prevented from desktop or hang on wall, use and show slightly trouble.

Summary of the invention

(1) the technical issues of solving

In view of the deficiencies of the prior art, the utility model provide it is a kind of with storage receive function anti-memory eye test dress It sets, mainly solves the problems, such as existing:

1, relatively good for some people's memory since the test letter in visual chart is often fixation, remember soon Firmly these test alphabetic directions, will make test result deviation occur, influence diagnosis of the doctor to eye eyesight.

2, most of visual charts are all to need to be placed on desk, and without support frame, when placement can be tilted, and not only be will affect The observation of patient is also inconvenient to move and fix.

3, eye test is all that must look into item in various physical examinations, and in large-scale physical examination, the single side of visual chart designs meeting So that the physical examination time lengthens.

Technical solution

In order to achieve the above object, the utility model is achieved by the following technical programs: a kind of to receive function with storage Anti- memory equipment for examining vision, including visual chart box and Chu Naxiang, the visual chart box vertical direction is provided with support rod, described It is socketed with fixed block outside support rod, horizontal sliding rail is provided with outside the fixed block, tells and is socketed with crawler belt outside fixed block, The crawler belt is internally provided with horizontal sliding slot, and the sliding rail is matched with sliding slot, and the track outer surface is provided with test symbol Number, pass through rivet interlacement between the test symbol and the crawler belt；Visual chart box lower end two sides are fixedly connected to arc Plate；Case arc panel lower end described in two groups is received in the storage, and the storage receives case front end face and is provided with chamber door, and left and right outer wall two sides are set It is equipped with handle, the visual chart box bottom is fixedly connected with connecting rod, and the connecting rod is actively socketed on the storage and receives inside case, The connecting rod bottom end is provided with universal wheel, and the storage receives bottom end and is provided with groove.

Preferably, the storage receives the depth of groove at bottom end and is greater than universal wheel diameter, and the connecting rod is through offering circle Shape through-hole is plugged with gag lever post in the circular through hole.

Preferably, the visual chart box is frame structure, and two plane of front and back is transparent plastic.

Preferably, the storage, which is received, opens inside case there are four circular through hole, and the connecting rod passes through through-hole and the universal wheel Connection.

Preferably, the track outer surface is provided with uniform vertical line, and the height of crawler is consistent with the fixed block height, The crawler belt is fitted closely with the fixed block.
