Abstract

The invention relates to a detection device, in particular to a color blindness detection device. The technical problem is to provide a color blindness detection device which can provide more completecolors and the detection result is more accurate. The color blindness detection device comprises a mounting block, a chair leg, a pulley, a flat belt, a first support rod, a frame body, a baffle plate, a bearing seat, a first rotating rod and the like; the left and right sides are connected with the chair legs at that bottom of the mount block; an inner cavity is arranged at the middle of the mounting block; a belt pulley is rotatably connected at the left and right parts of the mounting block in the inner cavity; and a flat belt is wound on the belt pulley at the left and right pulleys. As people rotate that rotate lever counterclockwise, finally, the mounting rod drives the pulleys of the left and right sides to rotate clockwise by pushing the handle upward, so that the colored cards appear on the frame, and the baffles of the left and right sides can block other colored cards, so that the examiner can concentrate his attention and recognize only one card color at a time, so that the detection result is more accurate.

Description

technical field [0001] The invention relates to a detection device, in particular to a color blindness detection device. Background technique [0002] As a chromosomal genetic disease, the incidence of color blindness in the population is increasing year by year, and the number of carriers is gradually increasing. Compared with normal people, the ability of color blindness to identify certain colors is abnormal, which may have a certain impact on daily life. Therefore, many institutions The unit will test the color blindness of employees before they enter the job. Usually, they will take a few colored cards or a book with several fixed colors for the testers to read and identify. Because the color is fixed and single, it is not diverse enough. This makes the detection results not accurate and reliable enough. Contents of the invention [0003] In order to overcome the shortcomings of single fixed color and inaccurate detection results in traditional color blind detection ...
