Abstract
The invention belongs to the technical field of visual testing tools, and particularly relates to a flexibly converted simple visual chart. The invention discloses the flexibly converted simple visual chart which is characterized by comprising a background plate, wherein the background plate is divided into multiple visual numerical parts from upside to downside; an E-shaped testing plate is hinged to each visual numerical part; the size of the E-shaped testing plate in each visual numerical part matches with the visual numerical value in each visual numerical part. The flexibly converted simple visual chart has the beneficial effects of being capable of changing opening direction of the E-shaped testing plates at any time, having better uncertainty and flexibility, and being capable of testing vision more exactly and increasing accuracy.
Description
Technical field
The invention belongs to vision and detect apparatus technical field, particularly relate to a kind of can the simple and easy visual acuity chart of flexible conversion.
Background technology
At present, when carrying out vision detection, generally visual acuity chart is used.Visual acuity chart is generally all be distributed with vision value region, and vision value region internal fixtion is provided with several " E " font check-out consoles, and the opening direction of each " E " font check-out console is unordered in a jumble.When concrete detection, be all generally point to certain " E " font check-out console, then allow detected person point out the opening direction of " E " font check-out console.This type of visual acuity chart also exists defect: because " E " font check-out console is fixedly installed, so its arrangement is changeless, so when detection, only need people the distribution situation of " E " font check-out console on visual acuity chart to be memorized, then just can point out direction according to the position of instruction, thus lose the effect of vision detection.
Summary of the invention
The object of the invention is to solve above-described technical problem, there is provided one can change the opening direction of " E " font check-out console at any time, have better uncertainty, motility, that more accurately can measure vision can the simple and easy visual acuity chart of flexible conversion, and its technical scheme is as follows:
A kind of can the simple and easy visual acuity chart of flexible conversion, it is characterized in that, described the simple and easy visual acuity chart of flexible conversion can comprise background board, described background board is separated into several vision numerical parts from top to bottom, hingedly in described each vision numerical part be provided with one " E " font check-out console, the described size of " E " font check-out console in each vision numerical part and the vision numerical value in vision numerical part match.
Optimal way is, the back of described background board is provided with luminous source.
Provided by the invention can the simple and easy visual acuity chart of flexible conversion, when in use, described background board is separated into several vision numerical parts from top to bottom, and vision numerical part can know the vision numerical value of testee accurately.Hingedly in described each vision numerical part be provided with one " E " font check-out console, hinged " E " font check-out console, when test, can the different openings direction of replacing " E " font check-out console at any time, thus there is more uncertainty, detected person can not be remembered, thus improve the accuracy of vision detection.
The back of the background board that the present invention is further described is provided with luminous source.When light is insufficient, luminous effect can be played preferably, thus the accuracy detected is improved.
The invention has the beneficial effects as follows: the opening direction that can change " E " font check-out console at any time, has better uncertainty, motility, more accurately can measure vision, improves its accuracy.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1:
As shown in Figure 1, a kind of can the simple and easy visual acuity chart of flexible conversion, it is characterized in that, described the simple and easy visual acuity chart of flexible conversion can comprise background board 1, described background board 1 is separated into several vision numerical parts 2 from top to bottom, hingedly in described each vision numerical part 2 be provided with one " E " font check-out console 3, the described size of " E " font check-out console 3 in each vision numerical part 2 and the vision numerical value in vision numerical part 2 match.
Optimal way is, the back of described background board 1 is provided with luminous source 4.
When in use, only need to rotate the E in different vision numerical part " opening direction of font check-out console, carries out detection to detected person just passable.Provided by the invention can the simple and easy visual acuity chart of flexible conversion, when in use, described background board is separated into several vision numerical parts from top to bottom, and vision numerical part can know the vision numerical value of testee accurately.Hingedly in described each vision numerical part be provided with one " E " font check-out console, hinged " E " font check-out console, when test, can the different openings direction of replacing " E " font check-out console at any time, thus there is more uncertainty, detected person can not be remembered, thus improve the accuracy of vision detection.
Claims (2)
1. one kind can the simple and easy visual acuity chart of flexible conversion, it is characterized in that, described the simple and easy visual acuity chart of flexible conversion can comprise background board, described background board is separated into several vision numerical parts from top to bottom, hingedly in described each vision numerical part be provided with one " E " font check-out console, the described size of " E " font check-out console in each vision numerical part and the vision numerical value in vision numerical part match.
2. as claimed in claim 1 can the simple and easy visual acuity chart of flexible conversion, it is characterized in that, the back of described background board is provided with luminous source.
