Abstract

The invention relates to a testing device, in particular to a color blind testing device. Therefore, the technical problem of the present invention is to provide a color-blindness test device that can randomly change the number of tests and has more accurate test results. The technical solution is: a color-blindness testing device, including a mounting frame, legs, a first gear, a second gear, a third gear, a first color plate, etc.; The front side is sequentially connected with a first gear, a second gear and a third gear in rotation from top to bottom. In the present invention, the tester rotates the rocker to drive the first color board and the second color board to rotate, and achieves the effect of randomly selecting test numbers; by moving the first connecting rod left and right, the second color board is driven to swing left and right, so that the rubber on the left and right sides The seat slows down the speed at which the second color plate stops rotating, preventing the left and right rubber seats from violent friction, causing excessive wear and affecting the service life of the equipment.

Description

technical field [0001] The invention relates to a testing device, in particular to a color blind testing device. Background technique [0002] As a chromosomal genetic disease, the proportion of color blindness in the population is increasing year by year. Because the disease will affect the ability of human eyes to distinguish colors, many units or companies will conduct color blindness tests on employees before recruiting. Most color blindness detection equipment is Use cards with numbers written in advance, and let the staff judge whether they can see the numbers clearly after watching them. Because the cards made in advance are too simple, it is impossible to randomly change the numbers and color combinations of the test, which will lead to inaccurate final color blindness test results. It makes the unit or company unable to make a good judgment. Contents of the invention [0003] In order to overcome the shortcomings of the traditional color-blindness test method tha...
