Abstract
The utility model relates to an optics demonstrating training aid which comprises a casing, a support, a screen, a slider, a connection rod, a draw bar and a light source, wherein the casing and the support are fixed on a baseboard, the screen with a small hole is arranged in the middle and fixed on the baseboard and between the imaging screen and the slider, the imaging screen is fixed on the casing, the slider penetrates through a connection rod fixed on the support, the draw bar penetrates through the hole of the casing to be connected with the slider, and a window is arranged on the casing. The optics demonstrating training aid demonstrates how a small hole can image through a simple structure, enables students to understand the optics theory easily, reduces learning difficulty and increases learning interest.
Description
Technical field
The utility model relates to a kind of optical demo teaching aid.
Background technology
In teaching practice, character express for pinhole imaging system in optics, students is than indigestibility, need to utilize specific teaching aid to demonstrate explanation in the laboratory, but the condition that there is no the laboratory in the remote districts of some schools especially economics of underdevelopment, can't carry out the pinhole imaging system demonstration and verification, increase the learning difficulty of students, reduce learning interest.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of optical demo teaching aid.
For addressing the above problem, the technical scheme that the utility model adopts is.
A kind of optical demo teaching aid teaching aid, comprise the housing and support, foraminate screen placed in the middle, connecting rod, the pull bar that are fixed on base plate, be placed on the light source on slide block, described screen is fixed on base plate, and between imaging screen and slide block, imaging screen is fixed on housing, slide block passes and is fixed in connecting rod on support, and the hole that pull bar passes housing is connected with slide block, has window on housing.
It is imaging how that the utility model uses simple structure to demonstrate aperture, makes students easier understand this optical principle, has reduced learning difficulty, has increased learning interest.
Description of drawings
Below in conjunction with accompanying drawing, a kind of optical demo teaching aid of the utility model is described further.
Fig. 1 is the structural representation of a kind of optical demo teaching aid of the utility model.
Embodiment
