Description
Technical field:
The present invention relates to the technical field of medical science eyesight testing apparatus tool, it is specifically related to a kind of vision of multi-functional detection
Table.
Background technology:
Visual acuity chart is the chart for measuring vision.What visual acuity chart used by medical science detection mainly checked is central vision, that is,
Check the recessed visual acuity of macula retinae district center, thus the preliminary situation of visual function can easily and rapidly be recognized, to oculopathy
Clinical conditions have important meaning.Although existing visual acuity chart possesses multiple such as international standard visual acuity chart, logarithm visions
Table, Lan Shi ring visual acuity chart etc., but these visual acuity charts are typically white gravoply, with black engraved characters, only possess the detection function of myopia or hypermetropia, separately
Outward, on these visual acuity charts, the direction of e word, position are all fixing, and some cherish the people of cheating psychology to improve testing result,
Whole visual acuity chart can be learnt off, lead to testing result that mistake occurs.
Content of the invention:
The purpose of the present invention aims to solve the problem that the problem that prior art exists, and provides one kind can detect anerythrochloropsia simultaneously, and e
The visual acuity chart of the multi-functional detection of the variable anti-cheating of word direction.
The present invention relates to a kind of visual acuity chart of multi-functional detection, including rectangular panel body, in described rectangular panel body, form two
Road runs through the slot of rectangular panel body upper surface, is inserted with black plate and red plate in described slot respectively；

The handle of stirring of arc shape is formed on the circumferential edges line of face, described handle of stirring is located between adjacent locating slot.
By technique scheme, the visual acuity chart of the present invention, when using, black inserting board is enclosed within rectangular panel body front end
Slot in, black plate is connected with e font groove, and such testing staff can be seen that surplus, Ke Yizuo by e font groove
Use for common visual acuity chart；By black plate and red plate in twice slot reversing of position so that red plate moves
To in the slot of rectangular panel body front end, such testing staff by e font groove see for The Scarlet Letter, exist with the cooperation of green coating
It is collectively used for detecting anerythrochloropsia.In detection, each round turntable in green coating can be recessed in corresponding circle
Rotate in groove so that the e font groove direction-changeable of each position, testing staff can be avoided because learning off visual acuity chart and
Lead to testing result deviation, specifically, stir and stir handle so that locating slot on round turntable departs from mesh on round turntable
Front positions ball head column plug and is embedded on the bulb of next positioning ball head column plug, and on round turntable, two of relative position are fixed
The line of position groove is horizontal line or vertical curve once stirs handle then 90 degree of round turntable rotation so that stirring, so that e
Font groove is correctly changed direction it is ensured that testing result is accurate.
By such scheme, the visual acuity chart of the multi-functional detection of the present invention can detect on the basis of normal vision table simultaneously
Anerythrochloropsia, and the direction-agile of each e word, thus can prevent testing staff's cheating from learning off whole visual acuity chart and leading to examine
Survey result and mistake occurs.
A kind of preferred as such scheme, described e font groove is in from top to bottom in the green coating of rectangular panel body
The horizontally-arranged arrangement of multiple tracks, form the e font groove horizontally-arranged with multiple tracks in the rectangular panel body between described twice slot corresponding
Horizontal grooving, described horizontal grooving connects twice slot.By such scheme, the setting of horizontal grooving makes to be used for examining when needs
Survey during anerythrochloropsia it is not necessary to by black plate and red plate reversing of position in twice slot, and only need to be by the black of front end
Plate is extracted out from the slot of rectangular panel body front end, and such testing staff also can be seen red by e font groove and horizontal grooving
Word, makes staff laborsaving and works more efficient.
A kind of preferred as such scheme, the slot adjacent with rectangular panel body of the circular groove in described green coating
Do not connect, the medial extremity of described round turntable stretches out circular groove and the slot adjacent with rectangular panel body is connected.
A kind of preferred as such scheme, the green coating of described e font groove both sides forms twice vertical
Arithmetic series, described arithmetic series is corresponding with each horizontally-arranged e font groove respectively.
A kind of preferred as such scheme, the upper surface of described black plate and red plate all forms portable
Ear.
A kind of preferred as such scheme, in described green coating the multiple e font grooves on multiple round turntables
In the different shapes of not of uniform size, direction.
A kind of preferred as such scheme, the upper surface left and right sides of described rectangular panel body forms hangers, described extension
