Abstract

The invention relates to a detector, in particular to a color blindness detector. The color blindness detector achieves the technical purposes that attention of children can be attracted, and errors can be avoided. According to the technical scheme, the color blindness detector comprises a base, an installing column, a supporting rod, an arc frame, a pointer, an annular frame, a square block, connecting blocks, a rotating wheel, a first spring, a friction rod, a sliding block, a sliding rail and the like; the installing column is connected to the top of the base, the supporting rod is connected to the upper portion between the left and right walls inside the installing column, the rotating wheel is rotationally installed in the middle of the front side of the supporting rod, four connecting blocks are evenly connected to the outer side of the rotating wheel at intervals, and the annular frame is connected to the outer sides of the four connecting blocks. A medical worker rotates the annular frame so that the pointer is pointed to the square block of the needed color, and color blindness detection can be performed on children; the position of the square block can be fixed through the friction rod, the phenomenon that the square block rotates freely due to the external force effect is avoided, and the detection result accuracy can be ensured.

Description

technical field [0001] The invention relates to a detector, in particular to a color-blind detector. Background technique [0002] When a child over the age of three is damaged due to genetics or retinal damage, different degrees of color perception disorders may occur, resulting in the child being unable to correctly identify some or all colors. The ophthalmology department of the hospital usually puts the detection tools on the table in front of the child to guide the child to identify the corresponding color by making the pointer indicate the blocks of different colors, but these detection tools are too boring for children , no play value, it is difficult for children to focus on the color above; if the blocks on these detection tools are affected by external forces such as wind, they are easy to rotate, resulting in inaccurate alignment of the pointer and deviation, resulting in errors . Contents of the invention [0003] In order to overcome the shortcomings of the ...
