The invention discloses a physics lens demonstration device, and relates to the technical field of teaching aids. The device comprises a supporting storage rack, an operating device and demonstrationsupplies, wherein a storage box and a storage cabin are arranged on the surface of the supporting storage rack; the surface of the supporting storage rack is connected with a lifting column; the operating device comprises a supporting plate, a connecting column and a sliding rod which are in mortise and tenon fit. According to the invention, the demonstration device is provided with the supportingstorage rack, the operating device and a demonstration article, so that the demonstration device is convenient to assemble and disassemble, and can be used for other demonstrations according to teaching requirements besides demonstrating a lens imaging principle; the storage box and the storage cabin are arranged on the surface of the supporting storage rack, so that all parts mounted on the surface of the demonstration device can be effectively stored, and the teaching aid is prevented from being damaged; a lifting column and an adjusting knob are arranged on the surface of the supporting storage rack, so that the demonstration height is conveniently adjusted; and the connecting column and the sliding rod are in mortise and tenon connection, so that mounting and dismounting of the sliding rod are facilitated, and storage is facilitated.
Description
technical field [0001] The invention belongs to the technical field of teaching aids, in particular to a physics lens demonstration device. Background technique [0002] As we all know, in teaching activities, many subject knowledge needs to be demonstrated by using various teaching aids, so that students can understand related subject knowledge, especially the principle of lens imaging in physics. By using teaching aids, the light in the process of lens imaging can be displayed more clearly A good lens demonstration device must be able to show the principle of lens imaging more clearly, and it must also be easy to operate, which is conducive to the use of teaching staff in classroom teaching. [0003] Now the common lens demonstration device is often composed of a demonstration stand and demonstration supplies. Although the structure is simple, it takes up more space due to its large size. At the same time, because the lens imaging principle is not often learned and used, i...
