[0002] The popular science experiment teaching box is a teaching aid for people to conduct popular science experiments. When conducting popular science pinhole imaging experiments, the teaching box is often used for popular science. It is mainly composed of popular science experimental equipment and the teaching box. When conducting popular science pinhole imaging, the equipment is placed in the correct position inside the teaching box, and then popular science is carried out through the experimental equipment.

[0003] The inventor discovered in daily use of the popular science experiment box that, when conducting popular science pinhole imaging experiments, it is generally necessary to adjust the size of the small hole on the baffle. Since the small hole on the baffle is usually fixed, it is inconvenient to change the size of the small hole, which results in the inability to complete the entire pinhole imaging experiment, thus causing an impact. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a portable science popularization experiment teaching box.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a portable science popularization experiment teaching box, comprising a box, a baffle is arranged inside the box, an adjustment device is arranged on the surface of the baffle, a binding device is arranged on the side of the box, a display panel is fixedly connected to the inner wall of the box, a box cover is rotatably connected to the upper top of the box, the adjustment device comprises a rectangular groove opened on the top of the baffle, a slide plate is slidably connected to the inside of the rectangular groove, adjustment holes of different sizes are opened on the surface of the slide plate, and a through groove is opened on the surface of the baffle.

[0006] The effect achieved by the above components is: under the action of the adjusting device, the size of the hole opened on the baffle surface can be adjusted, so that the pinhole imaging experiment can be carried out more completely. When the experimental box is needed, the candle inside the experimental box is lit, and the influence of the candle appears on the surface of the display board through the small hole opened on the baffle surface, thereby completing the pinhole imaging experiment and achieving the role of popular science.

[0007] Preferably, a groove is provided inside the box, a fixing rod is fixedly connected inside the groove, a sliding block is slidably connected to the surface of the fixing rod, and a baffle is fixedly connected to the upper top of the sliding block.

[0008] The effect achieved by the above components is that under the action of the slider, the baffle can slide, thereby achieving the effect that the distance between the baffle and the candle can be adjusted, thereby achieving the effect that the distance has no effect on the imaging.

[0009] Preferably, a circular hole is formed on the inner wall of the groove, and a damping rod is fixedly connected to the side surface of the sliding block.

[0010] The effect achieved by the above components is that, under the action of the damping rod and the round hole, the slider can be fixed after being moved to a suitable position.

When conducting an experiment to demonstrate pinhole imaging, when it is necessary to adjust the size of the hole on the baffle surface, the slide plate is slid up and down inside the rectangular groove, thereby blocking the through groove and leaving only the adjustment hole opened on the surface of the slide plate, thereby achieving the effect of adjusting the size of the hole. When it is necessary to adjust the distance between the baffle and the candle, the baffle can slide under the action of the slider, thereby achieving the effect of adjusting the distance between the baffle and the candle, thereby achieving the effect of whether the distance affects the imaging. Under the action of the damping rod and the circular hole, the slider can be fixed after moving to the appropriate position. Under the action of the first spring, the clamping rod is inserted into the through hole in a self-locking manner, thereby achieving a fixing effect, thereby achieving an adjusting effect.

[0020] The effect achieved by the above components is: under the action of the second spring, the limit rod can be firmly inserted into the interior of the circular groove, thereby achieving the limiting effect. When the experiment is completed, the end of the strap with the buckle is inserted into the interior of the card frame. Under the action of the locking rod, the buckle at one end of the strap is fixed inside the card frame, so that the box cover is fixed by the strap, avoiding the risk of the box cover opening. If the strap extends too much, the rotating rod is rotated, so that the strap is wrapped around the surface of the rotating rod. Under the action of the second spring, the limit rod can be firmly inserted into the interior of the circular groove, thereby achieving the limiting effect, thereby achieving the binding effect.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by arranging an adjustment device, when it is necessary to adjust the size of the hole on the surface of the baffle, the slide plate is slid up and down inside the rectangular groove, so that the through groove can be blocked, leaving only the adjustment hole opened on the surface of the slide plate, thereby achieving the effect of adjusting the size of the hole; when it is necessary to adjust the distance between the baffle and the candle, the baffle plate can slide under the action of the slider, thereby achieving the effect of adjusting the distance between the baffle plate and the candle, thereby achieving the effect of whether the distance affects the imaging; under the action of the damping rod and the circular hole, the slider can be fixed after moving to the appropriate position; under the action of the first spring, the clamping rod is self-locking and inserted into the inside of the through hole, thereby achieving the effect of fixing, thereby achieving the effect of adjusting, thereby solving the problem that the hole of the baffle inside the pinhole imaging cannot be adjusted.
