Abstract
The invention relates to a medical appliance, in particular to a translation rotary type vision measuring instrument. The vision measuring instrument comprises side wheels, rotating shafts, a light box, film belts, a light tube, an upper border, a lower border, convex teeth and square holes, wherein the upper end and the lower end of the light box are respectively provided with the upper border and the lower border which are clamped with the light box; the left side and the right side of the light box are respectively provided with a rotating shaft which is vertically arranged, and a pluralityof the side wheels with equal diameters are sleeved on each rotating shaft; the circumference of each side wheel is provided with a plurality of convex teeth which are uniformly distributed; and a film belt with characters is respectively sleeved on each pair of the side wheels; and the upper edge and the lower edge of each film belt are provided with the square holes which are distributed with equal distances and matched with the convex teeth of the side wheels. The invention can avoid the problem of influencing the accuracy of vision detection by artificial memories.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of translation rotary type vision measuring instrument.
Background technology
Existing common visual acuity chart, its surperficial character is changeless, therefore when measuring vision, no matter have a mind to or all certain memory can be arranged to the position of visual acuity chart character unintentionally, so give and measure vision and brought trouble, because to the memory of visual acuity chart character and the accurate vision of test eye.
Summary of the invention
The present invention is for the deficiencies in the prior art, the translation rotary type vision measuring instrument that provides a kind of character to change are provided.
The scheme that solves the technology of the present invention problem is: translation rotary type vision measuring instrument is made of cincture, rotating shaft, lamp box, film band, fluorescent tube, upper side frame, lower frame, double wedge and square hole.Wherein, lamp box is the box-like body of cuboid, and lamp box is made by printing opacity and opaque and white lucite.The two ends up and down of lamp box have the upper side frame and the lower frame of engaging with it respectively.The rotating shaft that a vertical layout is each side arranged of lamp box, the upper and lower side of each rotating shaft is fixed with upper side frame and lower frame respectively.Be with the cincture of a plurality of equal diameters in each rotating shaft, cincture and rotating shaft are in active relationship, and a plurality of equally distributed double wedges are arranged on the circumference of cincture.Each is to being with a film band that has character on the cincture, the top edge of film band and lower edge have equidistant square hole that matches with the double wedge of cincture.The internal fixation of lamp box has fluorescent tube.
Adopt such scheme, can reach following effect:
Before giving a test of one's eyesight, the doctor turns cincture, makes film band surface translation at lamp box under the drive of cincture, whenever moves a character, is exactly a kind of new arrangement mode.So just can avoid the accuracy that affects one's power of vision and detect because of artificial memory.
Description of drawings
Fig. 1 is a transverse cross-sectional view of the present invention;
Fig. 2 is a structural representation of the present invention.
Among the figure: 1. cincture 2. rotating shafts 3. lamp boxes 4. film bands 5. fluorescent tubes 6. upper side frames 7. lower frames 8. double wedges 9. square holes
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Translation rotary type vision measuring instrument is made of cincture 1, rotating shaft 2, lamp box 3, film band 4, fluorescent tube 5, upper side frame 6, lower frame 7, double wedge 8 and square hole 9.Wherein, lamp box 3 is the box-like body of cuboid, and lamp box 3 is made by printing opacity and opaque and white lucite.The two ends up and down of lamp box 3 have the upper side frame 6 and the lower frame 7 of engaging with it respectively.The rotating shaft 2 that a vertical layout is each side arranged of lamp box 3, the upper and lower side of each rotating shaft 2 are fixing with upper side frame 6 and lower frame 7 respectively.Be with the cincture 1 of a plurality of equal diameters in each rotating shaft 2, cincture 1 is in active relationship with rotating shaft 2, and a plurality of equally distributed double wedges 8 are arranged on the circumference of cincture 1.Each is to being with a film band 4 that has character on the cincture 1, the top edge of film band 4 and lower edge have equidistant square hole 9 that matches with the double wedge 8 of cincture 1.The internal fixation of lamp box 3 has fluorescent tube 5.
Before giving a test of one's eyesight, the doctor turns cincture 1, makes film band 4 surface translation at lamp box 3 under the drive of cincture 1, whenever moves a character, is exactly a kind of new arrangement mode.So just can avoid the accuracy that affects one's power of vision and detect because of artificial memory.
