The visual acuity chart box comprises a box body, rotary shafts, a visual acuity chart, motors, speed reducers and optotype dials, wherein the rotary shafts comprise a first rotary shaft and a second rotary shaft, the visual acuity chart winds around the first rotary shaft and the second rotary shaft, output shafts of the motors are connected with the rotary shafts, the rotary shafts and the visual acuity chart are arranged in the box body, a window corresponding to the visual acuity chart is formed in the box body, each optotype dial comprises a dial surface and a pointer, the dial surface is located at the top of the box body, and the pointer is connected with the corresponding rotary shaft through the corresponding speed reducer. The portable and changeable visual acuity chart box is compact in structure and convenient to carry and can effectively prevent cheating in visual acuity detection.
Description
Technical field
The invention belongs to medical treatment auxiliary detection technique field, be specifically related to a kind of portable alterable visual chart box.
Background technology
Quickly detect identification personnel's vision at present frequently with visual acuity chart, but existing visual acuity chart is strip, and with the back of the body
The visual chart box of light not only volume is big, and detects symbol and fix, if the shaped position that detected personnel remember detection symbol will
Reduce the accuracy of vision detection greatly, and the visual chart box of strip carries the most very inconvenient, it is therefore necessary to design one
Kind novel can be convenient for carrying and can be with the visual chart box of transition detection symbol.
Summary of the invention
According to above the deficiencies in the prior art, the technical problem to be solved is to propose a kind of portable alterable visual acuity chart
Case, drives the visual acuity chart being rolled into tubular to rotate by arranging roller bearing, thus occurs detection symbol at random, improve vision detection
Accuracy, reduces the volume of visual chart box.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: a kind of portable alterable visual chart box, and it is special
Levying and be, described visual chart box includes casing, rotating shaft, visual acuity chart, motor, decelerator and sighting target graduated disc, described rotating shaft bag
Including the first rotating shaft and the second rotating shaft, visual acuity chart is wound in the first rotating shaft and the second rotating shaft, and described motor output shaft is connected with rotating shaft,
Described box house is located at by rotating shaft and visual acuity chart, and casing is provided with the form that visual acuity chart is corresponding, and described sighting target graduated disc includes card
And pointer, described card is positioned at casing top, and described pointer is connected with rotating shaft by decelerator.
Described visual acuity chart is provided with one by one by the sighting target symbol of form, and described sighting target symbol grades by size level and is arranged in order, often
Individual grade includes the sighting target symbol that multiple direction equal in magnitude is different.Described visual acuity chart is semi-transparent white background flexible material, described regards
Reference symbol number is black, and is divided into 14 grades to be arranged in order from big to small, four that sized by each grade, equal direction is different
Sighting target symbol.Described card divides 14 high ranges, and each high range divides again 4 down scales, each scale respectively with sighting target symbol pair
Should.In described casing, window dead astern is provided with brightness adjustable light sources.Described box bottom center is provided with height adjustable support,
It is provided with handle in casing both sides.It is provided with dustproof glass at described form.
The medicine have the advantages that and set gradually detecting symbol on visual acuity chart by grade, volume, on cylinder, makes detection symbol on-demand
Occur at window, the most i.e. save space so that it is compact conformation, again because the symbol of detection is the control according to user
Occur, it is to avoid the detection inaccurate situation caused by memory visual acuity chart because of detected person.
Accompanying drawing explanation
Below the content expressed by this specification accompanying drawing and the labelling in figure are briefly described:
Fig. 1 is the structure diagram of a kind of portable alterable visual chart box of the detailed description of the invention of the present invention.
Fig. 2 is the one portable alterable visual chart box top view of the detailed description of the invention of the present invention.
In figure, 1, casing, 2, visual acuity chart, 3, rotating shaft, 4, light source 5, sighting target graduated disc.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the shape of each component that the detailed description of the invention of the present invention is the most involved,
Structure, mutual alignment and annexation, the effect of each several part and operation principle, manufacturing process between each several part and operate with
Methods etc., are described in further detail, to help those skilled in the art to have inventive concept, the technical scheme of the present invention more
Completely, accurate and deep understanding.
As it can be seen, a kind of portable visual acuity table case includes casing 1, visual acuity chart 2, rotating shaft 3, light source 4 and sighting target graduated disc 5.
Being provided with window on casing 1, be provided with rotating shaft 3 at the two ends of casing 1 window, be provided with motor in rotating shaft 3, motor can control
Two rotating shaft rotating in same directions, its visual acuity chart 2 two ends are rolled up respectively in two rotating shafts 3, and rotating shaft 3 rotates and drives visual acuity chart 2 to rotate advance,
Detection symbol on visual acuity chart 2 passes sequentially through the window of casing 1, and the detection symbol of described visual acuity chart 2 is that black divides from big to small
14 grades are arranged in order, and four detection symbols that sized by each grade, equal direction is different, described visual acuity chart 2 material is
Semi-transparent white background flexible material.Being provided with lamp source 4 in the dead astern of casing 1 window, light can will be shone by the visual acuity chart 2 of window
Bright.Being provided with graduated disc 5 on casing 1, connecting in rotating shaft 3 one end has decelerator, and its decelerator outfan is provided with pointer,
Described pointer is positioned at the middle of graduated disc 5,5 points of 14 high ranges of described sighting target graduated disc, each high range divide again 4 little
Scale, it is corresponding that each scale detects symbol with it respectively.User can judge to be currently in window detection according to corresponding scale
Visual acuity chart 2 is turned to suitable position and tests detected person by the direction of symbol and size.
In enforcement, switch can be installed further in casing 1 side and control rotating and the bright level in lamp source 4 of rotating shaft 3 respectively.
