Problems solved by technology

[0002] At present, the myopia rate of students is getting higher and higher, and myopia has brought great troubles to students, especially in the experimental class, because students' myopia often leads to errors in experiments, especially in chemical experiments that require fine scales. Read more accurate readings of burettes, graduated pipettes and other utensils. The densely packed small scales have brought troubles to students with poor vision such as myopia, and therefore have a negative impact on the test.

Abstract

The invention discloses a scale reading assist device, which comprises a shell, and is characterized in that: the shell is a cube; the shell is a cylindrical hollow body; the circumferential surface of the cylindrical hollow body is provided with white sponge; one surface of the shell is provided with a convex lens frame; a convex lens is arranged on the frame; the convex lens frame is also provided with an adjustable screw rod; and the objective distance of the convex lens is adjusted by the screw rod. The scale reading assist device can magnify the scales of a container to increase definition, and is suitable to be used by crowds with different vision levels. In addition, the scale reading assist device has the advantages of simple structure and convenient use.

Description

Technical field: [0001] The invention relates to a scale reading assistant. Background technique: [0002] At present, the myopia rate of students is getting higher and higher, and myopia has brought great troubles to students, especially in the experimental class, because students' myopia often leads to errors in experiments, especially in chemical experiments that require fine scales. Read the more accurate readings of utensils such as burettes and graduated straws. The densely packed small scales bring troubles to students with poor eyesight such as myopia, and therefore have a negative impact on the test. Invention content: [0003] The object of the present invention is to solve the deficiencies in the prior art, and provide a scale reading assistant capable of enlarging the scale for easy reading, which has a simple structure and is easy to use. [0004] In order to achieve the above object, the technical scheme of the present invention is as follows: [0005] The ...
