The invention discloses a physics lens demonstration device and belongs to the technical field of teaching aids. The device comprises a supporting storage rack, an operating device and a demonstrationappliance; storage boxes and a storage cabin are arranged on the surface of the supporting storage rack; the surface of the supporting storage rack is connected with lifting columns; the operating device comprises a supporting plate, connecting columns and sliding rods, wherein the connecting columns are in mortise and tenon fit with the sliding rods. According to the physics lens demonstration device of the invention, the demonstration device is provided with the supporting storage rack, the operating device and the demonstration appliance, so that the demonstration device is convenient to assemble and disassemble, and can be used for other demonstrations according to teaching requirements besides the demonstration of a lens imaging principle; the storage boxes and the storage cabin arearranged 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; the lifting columns and an adjusting knob are arranged on the surface of the supporting storage rack, so that demonstration height is conveniently adjusted; and the connecting columns and the sliding rods are in mortise and tenon connection, so that the mounting and dismounting of the sliding rods 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 use various teaching aids for operation demonstration, so that students can understand related subject knowledge, especially the lens imaging principle 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 be easy to operate, which is conducive to the use of classroom teaching by academic staff. [0003] Now common lens demonstration devices are often composed of demonstration racks and demonstration supplies. Although the structure is simple, it takes up more space due to its large size; Storage, and our common demonstration devices are not conducive to storage because of the...
