Description

Imaging screen for imaging experiment of plane mirror

Technical Field

The utility model belongs to the technical field of the experiment teaching aid, in particular to level crossing formation of image experiment imaging screen.

Background

Planar mirror imaging is a physical phenomenon. Meaning that the light from the sun or lamp strikes a person, the mirror reflects the light back into the person's eye, and so we see a virtual image in the mirror.

In the subject teaching of primary schools and middle schools, the plane mirror imaging has very important teaching significance.

In experiments, a thin plate is usually used to replace a flat mirror, and a candle is used as a light source for the imaging characteristics of the difficult light source in the flat mirror.

But current formation of image screen is fixed the setting usually, and is perpendicular with the desktop when putting on the desktop for the candle only is put on the desktop, can only observe the formation of image screen and be the image under the 90 degrees states, and when needing to observe the image of other angles, then need take up the candle with the hand or incline the formation of image screen with the hand, and the operation is complicated, influences the experiment and observes.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide a level crossing imaging experiment imaging screen that can adjust observation angle.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a level crossing imaging experiment imaging screen, its characterized in that includes screen panel and supporting legs, the screen panel be provided with the rotation axis, the supporting legs on set up and supply the connecting hole that the rotation axis was inserted, the both ends of rotation axis be arranged in inserting the connecting hole, the screen panel can rotate around the rotation axis.

The working principle of the utility model is that the supporting legs are used for supporting the screen board on the desktop, and the screen board can be rotated around the rotating shaft by stirring the screen board, so that the inclination angle of the screen board can be adjusted in the experiment process, the observation of the imaging condition of the imaging screen in the plane mirror under different angles can be realized, and the operation is simple and convenient.

In the plane mirror imaging experimental imaging screen, the rotating shaft is located at the bottom of the screen plate.

In the plane mirror imaging experiment imaging screen, two ends of the rotating shaft are prism-shaped.

In the plane mirror imaging experiment imaging screen, two ends of the rotating shaft are in an octagonal prism shape.

In the plane mirror imaging experiment imaging screen, the screen plate has a plurality of experiment angles, and at least one experiment angle is that the screen plate is vertical to the horizontal plane.

In the imaging screen for the plane mirror imaging experiment, the screen plate is detachably connected with the supporting legs.

In the plane mirror imaging experiment imaging screen, the supporting legs are cuboid, and the connecting holes are formed in the middle of the supporting legs.

In the plane mirror imaging experiment imaging screen, the connecting hole is a through hole.

In the plane mirror imaging experiment imaging screen, the bottom surface of the supporting leg is provided with a material reducing groove.

Compared with the prior art, the utility model has the advantages of can adjust observation angle.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 3, the imaging screen for the plane mirror imaging experiment comprises a screen plate 1 and supporting legs 2, wherein the screen plate 1 is provided with a rotating shaft 3, the supporting legs 2 are provided with connecting holes 4 for inserting the rotating shaft 3, two ends of the rotating shaft 3 are inserted into the connecting holes 4, and the screen plate 1 can rotate around the rotating shaft 3.

In further detail, the axis of rotation 3 is located at the bottom of the screen 1.

To be more specific, both ends of the rotating shaft 3 are prism-shaped. The utility model discloses set up both ends and be prismatic rotation axis 3, connecting hole 4 also be with 3 assorted prismatic of rotation axis, realized the fixed of screen panel 1 through the mutual butt of prismatic perisporium, need not other fixed knot and construct, can not influence the rotation of screen panel 1 yet, simple structure.

Preferably, both ends of the rotating shaft 3 are octagonal. The two ends of the rotating shaft 3 can be arranged in the shapes of a hexagonal prism, a heptagonal prism, a nonagonal prism, a decagonal prism and the like according to requirements.

In further detail, the screen 1 has a plurality of experimental angles, at least one of which is the screen 1 perpendicular to the horizontal plane. Because the experiment angle of 1 perpendicular to horizontal plane of screen panel is most commonly used, the utility model discloses well natural setting up this experiment angle, when the both ends of rotation axis 3 were octagon shape, can also rotate screen panel 1 to personally submit 45 degrees's experiment angle with the horizontal plane.

In further detail, the screen panel 1 is detachably connected to the support legs 2. The screen panel 2 is convenient to splice and disassemble.

In more detail, the supporting legs 2 are rectangular, and the connecting holes 4 are formed in the middle of the supporting legs 2. Because the rotation axis 3 is located the bottom of screen panel 1 for supporting legs 2 set up the cuboid form can, can not interfere the rotation of screen panel 1, and supporting legs 2's simple structure, production is convenient, practices thrift the production material, and connecting hole 4 is seted up in the middle part of supporting legs 2 and can be so that supporting legs 2 atress is balanced, can be more stable put on the desktop.
