Description

Technical Field

[0001] The invention relates to the technical field of teaching demonstration, in particular to a teaching demonstration device with simulation function. Background Art

[0002] Pinhole imaging originated from an experiment done by an ancient Chinese scholar (Mozi) and his students. The experimental results explained the reason why the pinhole formed an inverted image and pointed out the rectilinear nature of light. This was the first scientific explanation of the straight-line propagation of light. Pinhole imaging uses a plate with a small hole to block between the wall and the object, and the reflection of the object will be formed on the wall. We call this phenomenon pinhole imaging.

[0003] For example, the publication number CN114495664A is an optical teaching demonstration device and method that is easy to adjust. Through the coordinated use of a base, a slide groove, a positioning groove, a limit rod, a hemispherical block, a slider, a mounting block and a positioning mechanism, the slider and the mounting block can slide and be fixed on the limit rod, avoiding the inconvenience of moving objects, pinhole shielding plates and imaging plates in traditional technologies, and can more intuitively display experimental phenomena and explain experimental principles. However, in actual use, the height of the light source and the pinhole cannot be adjusted. When the height of the light source deviates greatly from the pinhole, the light cannot be well focused when imaging through the pinhole, which will affect the imaging quality and viewing. In addition, during the simulation process, the light emitted by the light source is easily affected by brighter light from the outside world, which will cause blurred imaging and affect the imaging quality. There are certain usage defects.

[0004] Therefore, we proposed a teaching demonstration device with simulation function to solve the above problems. Summary of the invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the teaching demonstration device with simulation function is provided with a movable component above the fixed platform on one side, and the height of the vertical plate can be adjusted according to the height of the light source, so that the light is easier to focus, and the consistency of the light propagation path can be ensured, and the imaging distortion caused by the angle deviation can be reduced. When the height of the vertical pole is adjusted according to the height of the light source, the cover plate and the baffle plate can be driven to rotate, so that the external light can be shielded to prevent the strong external light from affecting the imaging quality. 1. A movable component is set above the fixed platform on one side. When performing a pinhole imaging simulation demonstration, a light source (such as a candle) is placed on the top of the placement platform. When adjusting the height of the vertical plate according to the height of the light source, the screw rod is rotated. After the screw rod is rotated, it drives the mounting plate to move through the connection with the threaded sleeve. During the movement, the mounting plate drives the positioning sleeve to slide on the positioning rod for limiting, so that the height of the through hole on the vertical plate is relatively level with the light source. Before the height of the vertical plate is adjusted, the cover plate is level with the base, which is convenient for the placement of the light source and the imaging plate. The light source will generate a certain amount of heat when burning and emitting light, avoiding burns when adjusting the height of the light source. After the mounting plate moves, the sliding sleeve can be pushed upward by the cross bar, so that the mounting rod can push the rotating member to rotate through the sliding connection between the sliding block and the sliding groove on the rotating member. After the rotating member rotates, the moving rod can be driven down through the cooperation of the sliding groove on the other side and the movable block, and the moving rod slides on the limiting sleeve. The movable block is pulled to slide inside the movable groove by the connecting rod, so that the cover plate can be covered above the light source, which can prevent the external light from affecting the imaging quality, and the connecting rod drives the movable rod to move while the cover plate rotates downward. After the movable rod moves, the sliding sleeve can be pulled to slide on the vertical rod, so that the baffle plate can be driven to rotate, so that the rotation of the baffle plate can further block the external light, avoiding the setting of a baffle plate on the front of the light source for blocking, and the baffle plate area is limited, and the external light can be effectively blocked by tilting at an angle without affecting the viewing effect. The height of the vertical plate can be adjusted according to the height of the light source through the movable component, so that the light is easier to focus, the consistency of the light propagation path can be ensured, and the imaging distortion caused by the angle deviation can be reduced. When the height of the vertical plate is adjusted according to the height of the light source, the cover plate and the baffle plate can be driven to rotate, so as to block the external light, which can prevent the external light from being strong and affecting the imaging quality. 2. Positioning components are symmetrically arranged on both sides of the two fixed tables. When adjusting the position of the vertical plate and the imaging plate, the two push plates are pinched to move, so that the push rod can be driven to slide on the U-shaped frame, and the movement of the push rod can drive the mounting frame to move, and the movement of the mounting frame drives the inclined rod to rotate. After the inclined rod rotates, the vertical rod can be pushed to slide on the U-shaped frame, so that the arc sleeve can be lifted, so that the rubber pad does not contact the fixed rod, and the fixed table can be moved so that the movable sleeve slides outside the fixed rod to adjust the position of the fixed table, which is convenient for adjusting the position of the vertical plate and the imaging plate, and is convenient for improving the clarity of imaging. After the fixed table is adjusted, the push plate can be loosened, and the vertical rod is reset under the action of the telescopic spring, and the telescopic spring is in a slightly stretched state, so that the rubber pad on the arc sleeve fits with the fixed rod, so that the fixed table is positioned. The positioning component is used to facilitate the adjustment of the position of the fixed table, and assists users to improve imaging quality, thereby improving convenience and practicality. 3. A fixing component is set on the top of the fixing table on the other side. When fixing the imaging plate, the imaging plate is inserted between the two clamps. The tops of the two clamps are provided with bending parts, so that the imaging plate can be pushed and moved through the opening between the two clamps, so that the clamping rod slides on the fixing seat and stretches the reset spring, and then the imaging plate can be auxiliary fixed by the two clamps. When removing the imaging plate, the imaging plate can be directly pulled apart from the clamp. The fixing component is convenient for users to fix the imaging plate, which improves convenience.

[0026] Embodiment 1: Figure 1-7As shown, a movable component 2 is arranged above a fixed platform 108 on one side.

During the movement, the mounting plate 109 drives the positioning sleeve 113 to slide on the positioning rod 114 for limiting, so that the height of the through hole on the vertical plate 110 is relatively level with the light source. Before the height of the vertical plate 110 is adjusted, the cover plate 103 is level with the base 1, which is convenient for the placement of the light source and the imaging plate.

After the rotating member 202 rotates, the moving rod 207 can be driven to descend through the cooperation between the sliding groove 203 on the other side and the movable block 206. The moving rod 207 slides on the limiting sleeve 210 to limit the position, and then the connecting rod 212 pulls the moving block 215 to slide inside the moving groove 214, so that the cover plate 103 can be covered above the light source to prevent the external light from affecting the imaging quality. When the cover plate 103 rotates downward, the connecting rod 212 drives the movable rod 213 to move. After the movable rod 213 moves, the sliding sleeve 218 can be pulled to slide on the vertical rod 217, so that the baffle 104 can be driven to rotate, so that the baffle 104 rotates to further block the external light. When adjusting the position of the vertical plate 110 and the imaging plate, the two push plates 310 are pinched to move, so that the push rod 307 can be driven to slide on the U-shaped frame 301, and the movement of the push rod 307 can drive the mounting frame 308 to move, and the movement of the mounting frame 308 drives the inclined rod 309 to rotate, and after the inclined rod 309 rotates, the vertical rod 302 can be pushed to slide on the U-shaped frame 301, so that the arc sleeve 303 can be lifted so that the rubber pad 304 does not contact the fixed rod 106, and the fixed platform 108 can be moved so that the movable sleeve 107 slides outside the fixed rod 106 to adjust the position of the fixed platform 108, so as to facilitate the adjustment of the position of the vertical plate 110 and the imaging plate, and to facilitate the improvement of the clarity of the imaging, and the push plate can be released after the fixed platform 108 is adjusted. 310, the vertical rod 302 is reset under the action of the telescopic spring 305, and the telescopic spring 305 is in a slightly stretched state, so that the rubber pad 304 on the arc sleeve 303 fits with the fixed rod 106, so that the fixed platform 108 is positioned, and when fixing the imaging plate, the imaging plate is inserted between the two clamps 403, and the tops of the two clamps 403 are provided with curved parts, so that the imaging plate can push the clamps 403 to move through the opening between the two clamps 403, so that the clamping rod 402 slides on the fixed seat 401 and stretches the reset spring 404, and then the imaging plate can be auxiliary fixed through the two clamps 403, and when the imaging plate is removed, the imaging plate can be directly pulled apart from the clamps 403.
