Abstract

The invention relates to a detection device, in particular to a portable color blindness detection device. Therefore, the technical problem of the present invention is to provide a portable color-blindness detection device with better use effect, strong randomness of detection patterns and difficult to find regularity. The technical embodiment of the present invention is: a portable color blind detection device, including a base, a shielding frame, a first roller, a first color frame, a diamond-shaped concave plate, a circular slide rail, a slider, a second color frame, a rotating Rods, cover plates, connecting rods, etc.; there is a shielding frame on the top of the base, and a second wheel groove is opened on the top of the shielding frame. The left and right sides of the second wheel groove are slidingly equipped with second rollers, and the bottom of the second wheel groove is uniform. There are arc grooves. In the present invention, through the arc-shaped groove at the bottom of the second roller, the tester can more clearly feel the rotating position of the digital hole when rotating, which is convenient for the tester to better grasp the displayed numbers, improves randomness, and avoids being tested. The human infers the displayed number based on the moving position of the number hole.

Description

technical field [0001] The invention relates to a detection device, in particular to a portable color blindness detection device. Background technique [0002] In daily life, some people are not sensitive to some colors and cannot distinguish specific colors, which brings inconvenience to life. In order to further detect the degree of insensitivity, color blindness tests are often carried out on these people, and at the same time, jobs with higher color requirements Color blindness detection is also required, but the current color blindness detection is usually judged by observing the numbers or patterns on some pictures. These pictures will cause wear and tear after long-term use, and even affect the detection effect, resulting in inaccurate detection; The pattern is relatively fixed, and the test personnel can easily guess the content of the corresponding pattern as long as they remember the position of the pattern in the atlas. Contents of the invention [0003] In ord...
