Abstract

The invention relates to test equipment, in particular to color blindness test equipment. In order to solve the technical problem, the invention provides the color blindness test equipment which can randomly change test digital and is more accurate in the test results. The technical scheme lies in that the color blindness test equipment comprises a mounting frame, support legs, a first gear, a second gear, a third gear, a first colored plate and the like, wherein the support legs are respectively arranged on the left side and the right side of the bottom of the mounting frame; and the first gear, the second gear and the third gear are sequentially and rotatably connected to the front side of the mounting frame from top to bottom. A tester rotates a shaking stem to drive the first colored plate and a second colored plate to rotate, so that the effect of randomly selecting the test digital is achieved. Through left-and-right movement of a first connecting rod, the second colored plate isdriven to swing left and right, so that left and right rubber seats can slow the rotation stopping speed of the second colored plate, and the condition that the left and right rubber seats generate acute friction to cause too high wear and tear to influence the service life of equipment is avoided.

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...
