Description

Technical Field

[0001] The present invention relates to the technical field of vision testing, and in particular to a vision testing device and a testing method for vision detection. Background Art

[0002] The quality of vision depends on vision. In other words, people with good vision can see farther and more clearly, and have a strong ability to recognize colors, space, distance, etc. Regular eye examinations are very important, and other physical diseases can also be discovered through examinations.

[0003] Visual acuity refers to the ability of the retina to distinguish images. The quality of visual acuity is determined by the ability of the retina to distinguish images. However, when the refractive media of the eye (such as the cornea, lens, vitreous body, etc.) become cloudy or there is a refractive error (including myopia, hyperopia, astigmatism, etc.), even if the retina functions well, the visual acuity will still decline. Therefore, visual acuity testing can accurately detect possible problems with the eyes. Currently, visual acuity testers are becoming more and more intelligent, tracking and monitoring the visual acuity of different individuals for a long time, screening for abnormal phototropism of the eyes, automatically judging the test results and recording and storing them, and drawing curves to analyze the trend of visual acuity changes.

When the light-shielding eye mask 13 is placed outside the disinfection mechanism 19, the ultraviolet lamp 1902 emits ultraviolet rays to irradiate the surface of the light-shielding eye mask 13 to kill bacteria on the surface of the light-shielding eye mask 13. At the same time, the setting of the shielding plate 1903 prevents the ultraviolet light from damaging the vision detection eyepiece 14 during sterilization.

[0039] As a further solution in the present invention, a V-shaped locking portion 5 is provided on one side of the two locking cover plates 2, and two locking grooves 25 are provided on both sides of the top of the tester main body 7. The size of the locking portion 5 is adapted to the internal space of the locking groove 25. When the locking cover plate 2 and the locking support 3 rotate, the locking portion 5 and the locking groove 25 are separated and engaged, thereby fixing the tester main body 7 inside the device housing 1. The tester main body 7 is charged while being fixed. The protruding design of the locking portion 5 can push the locking cover plate 2 with the help of the pressure of the tester main body 7 to complete the engagement between the locking portion 5 and the locking groove 25. It is simple and convenient to use.

[0040] As a further solution in the present invention, an upper limit support frame 16 and a lower limit support frame 18 are installed inside the movable support frame 17 through a torsion spring, and the upper limit support frame 16 and the lower limit support frame 18 are both composed of gas springs. When the movable support frame 17 is lifted up to push the tester main body 7 out of the equipment housing 1, one end of the upper limit support frame 16 and the lower limit support frame 18 composed of the gas spring pops out, and uses the thrust of the gas spring to contact the upper support seat and the lower support seat 21 respectively. The upper limit support frame 16 and the lower limit support frame 18 are combined with the movable support frame 17 to form a triangular support structure, which effectively avoids the shaking of the tester main body 7 during the vision test and improves the stability of the horizontal lifting of the tester main body 7.

[0041] As a further solution in the present invention, the side surfaces of the lower support seat 21 and the upper support seat are both arc-shaped structures, and the tail end and the head end of the lower support seat 21 and the upper support seat are provided with a C-shaped structure positioning portion, and the ends of the upper limit support frame 16 and the lower limit support frame 18 slide in the arc-shaped side surfaces of the lower support seat 21 and the upper support seat. When the tester body 7 is in the working state, the ends of the upper limit support frame 16 and the lower limit support frame 18 are embedded in the positioning portion at the tail end. When the tester body 7 is in the storage state, the ends of the upper limit support frame 16 and the lower limit support frame 18 are embedded in the positioning portion at the head end, thereby further improving the supporting stability of the triangular support structure formed by the upper limit support frame 16 and the lower limit support frame 18 combined with the movable support frame 17, thereby improving the stability and comfort during the vision test.
