Physical convex lens experimental demonstration device

Abstract

The invention relates to a demonstration device, and particularly relates to a physical convex lens experimental demonstration device, so as to solve the technical problem of providing a physical convex lens experimental demonstration device with the advantages of intuitive demonstration, time and labor saving and small labor intensity. In order to solve the above technical problem, the invention provides the physical convex lens experimental demonstration device, which comprises a trolley, a first cylinder, a first sliding block, a side plate, a first sliding rail, a rack, a gear, a convex lens, a second cylinder, a push plate, a placement plate, a supporting rod, a first connection rod, an electric winding wheel, a pulling wire, a second sliding block, a spring, a second connection rod, a third cylinder, a third sliding rail and a processing box, wherein the trolley is sequentially provided with the side plate, the first cylinder, the supporting rod, the second sliding rail and the processing box sequentially from left to right; the first sliding rail is arranged on the side plate; the first sliding block is arranged on the first sliding rail; the upper end of the first cylinder is connected with the rack; and the first sliding block is connected with the rack. Effects of intuitive demonstration, time and labor saving and small labor intensity are thus achieved.

Description

technical field [0001] The invention relates to a demonstration device, in particular to a physical convex lens experiment demonstration device. Background technique [0002] Physics is a subject that studies the most general laws of motion of matter and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles, and thus becomes the research basis of other natural science disciplines. Its theoretical structure fully uses mathematics as its working language, and experiments are the sole criterion for testing the correctness of the theory. It is the most sophisticated natural science discipline today. [0003] Convex lenses are made according to the principle of refraction of light. Convex lenses are lenses that are thicker in the center and thinner at the edges. Convex lenses are divided into biconvex, plano-convex, concave-convex (or ...
