Embodiment 1

[0024] see figure 1 , an optical experiment demonstration device used in physics teaching, including an experiment box 1 and a candle 5, in order to adjust the height of the experiment box 1, to facilitate students to observe, drive boxes 17 are symmetrically arranged on the left and right sides of the bottom of the experiment box 1 , the screw rod one 18 is set in the drive box 17, and the screw rod one 18 is rotationally connected with the drive box 17. The nut one 20 is arranged on the surface of the screw rod one 18, and the nut one 20 can rotate vertically with the screw rod one 18. Move up and down in the vertical direction, the nut-20 on the left and right sides are fixedly installed with the base 25, the upper surface of the base 25 is provided with a supporting box 30, and the top of the supporting box 30 is fixedly connected with the bottom wall of the experimental box 1 through a connecting rod, By turning the screw rods 18 on the left and right sides, the nut 20 dr...

Embodiment 2

[0031] see Figure 1-4 , on the basis of Embodiment 1, in order to facilitate the adjustment of the size of the small hole, the surface of the fixed plate 12 is provided with a through hole 34, the fixed plate 12 is provided with a sealing plate 33, and the surface of the sealing plate 33 is equidistantly arranged There are small holes 28 of different sizes, a runner 31 is arranged on the inside of the fixed plate 12, and a stay cord 32 is arranged on the surface of the runner 31, and the bottom of the stay cord 32 is fixedly connected with the sealing plate 33, and the runner 31 is on the right side. The side end is fixedly connected to the handle 2 35, and by turning the handle 2 35, the handle 2 35 drives the runner 31 to rotate, and the runner 31 drives the sealing plate 33 to move up and down in the vertical direction through the pull cord 32, so that the surface of the sealing plate 33 The small hole 28 is located at the center of the through hole 34, and the size of the...

Abstract

The invention discloses an optical experiment demonstration device applied to physics teaching, and relates to the technical field of physics teaching equipment. The device comprises an experiment boxand a candle, driving boxes are symmetrically arranged on the left side and the right side below the experiment box, first screws are arranged in the driving boxes, first nuts are arranged on the surfaces of the first screws, a base is fixedly arranged between the first nuts, a supporting box body is arranged on the upper surface of the base, and second screws are symmetrically arranged on the left side and the right side in the experiment box. The nuts drive the supporting box body above and the experiment box to move up and down in the vertical direction through the base, the height of theexperiment box is adjusted, and students can conveniently observe an experiment; a telescopic rod pushes a support and the candle to move up and down in the vertical direction, the height of the candle can be adjusted, and a height comparison test is facilitated; and the second nuts drives the candle and an imaging plate above the left and right sides respectively to move left and right in the horizontal direction, the distances between the candle and a fixing plate and between the imaging plate and the fixing plate are adjusted, and a distance comparison test is facilitated.

Description

technical field [0001] The invention relates to the technical field of physics teaching equipment, in particular to an optical experiment demonstration device applied to physics teaching. Background technique [0002] Light reflection is a physical phenomenon in nature. When light hits the interface between two media, some of the light changes its propagation direction and returns to the original medium to continue to propagate. This light reflection phenomenon is called light reflection, and light reflection is common. When light hits the surface of any object, reflection will occur. [0003] In the process of physics teaching, in order to facilitate students to understand the light source of small hole imaging, it is necessary to use optical instruments for experiments. The existing optical test box has a simple structure and is not easy to adjust, and it is difficult to adjust the size of the small hole in real time, which affects the efficiency of the experiment. .
