Description

Technical Field

[0001] The present invention relates to the technical field of physical experiment devices, and particularly to a combined optical mirror device for middle school physics experiments. Background Technique

[0002] In middle school physics teaching, the principle of lens imaging is the core content of the optical section. As a key teaching aid for demonstrating this principle, the optical mirror device plays an important role in helping students understand abstract optical knowledge. Currently, although the common middle school physics optical mirror devices on the market have the function of adjusting the distance between the light source and the imaging plate, which improves the flexibility of experiments to a certain extent, there are still significant deficiencies.

[0003] Although in the existing technologies, some optical mirror devices have achieved the adjustment of the distance between the light source and the imaging plate, increasing the flexibility of experiments, however, the experimental display effects of most optical mirror devices are average, lack diversity, and the display is monotonous.

[0004] On the one hand, most optical mirror devices are only equipped with a single type of lens, or although there are multiple lenses, they cannot be compared and demonstrated under the same experimental conditions. It is difficult for students to intuitively observe the differences in the imaging characteristics of different lenses under the same object distance and image distance conditions, resulting in an insufficiently profound and comprehensive understanding of the optical characteristics of the lenses. On the other hand, the existing devices have relatively single functions and lack the exploration design for the combined imaging of lenses. In actual optical applications, such as camera lenses and microscope objectives, multiple lenses often work together. However, traditional optical mirror devices cannot simulate this process, and it is difficult for students to come into contact with and understand the changes in the light propagation path and imaging effects after different lens combinations, greatly limiting the students' understanding of the complex optical working principle and being unfavorable for cultivating the students' practical ability and innovative thinking. Therefore, a combined optical mirror device for middle school physics experiments is proposed to solve the above problems. Summary of the Invention

[0005] To achieve the above object, the present invention provides the following technical solution: A combined optical mirror device for middle school physics experiments, including a base.

[0008] The moving assembly includes a second threaded rod. The second threaded rods are rotatably installed inside the front and rear sides of the base. A slider that is slidably installed on the inner wall of the base is threadedly connected to the outer surface of the second threaded rod.

[0009] Further, the distance adjustment assembly includes a worm. A worm is provided inside the left side of the base, and a worm gear is engaged with the top of the worm.

[0010] Further, threaded rods are fixedly installed on the outer surfaces of the two worm gears. Moving blocks are fixedly installed at the tops of the two threaded rods.

[0011] Further, the two imaging light screens are respectively arranged on the tops of the two moving blocks.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 6 , a combined optical mirror device for middle school physics experiments in this embodiment, includes a base 1. Two light sources 101, two identical first lenses 102 and two imaging light screens 103 are sequentially arranged on the top of the base 1 from right to left. A distance adjustment component 2 is arranged at the bottom of the two imaging light screens 103. Matching devices 104 are arranged on both the front and rear sides of the top of the base 1. Moving components 3 are arranged at the bottom of the two matching devices 104.

[0029] The base 1 serves as the basic support structure of the entire device. Its material can be selected from durable metals or engineering plastics, and its surface is treated with anti-slip to ensure the stability of the device during the experiment and avoid affecting the experimental results due to shaking. The two light sources 101 can use LED cold light sources, which have the advantages of stable brightness, low heat generation, and long lifespan, and can provide a continuous and stable light source for the experiment, facilitating students to clearly observe the light propagation and imaging process. The two identical lenses 102 have magnetic attraction blocks 1 at the bottom that cooperate with the magnetic attraction blocks 2 at the top of the base 1. High-strength magnetic materials are used, which can not only ensure the stable installation of the lens 102 on the base 1 but also facilitate disassembly and replacement. Under the same experimental conditions, students can intuitively observe the imaging situation of the lens on light under the same object distance and image distance conditions by comparing the imaging characteristics of the two lenses 102, thereby deepening the understanding of the basic optical characteristics of the lens. The two imaging light screens 103 are used to clearly receive the light imaging, and the distance adjustment component 2 provided at the bottom can flexibly adjust the position of the imaging light screen 103.

[0030] In the distance adjustment component 2, when the worm 201 is rotated, the worm wheel 202 meshing with the top of the worm 201 will rotate synchronously. The threaded rods 1 203 fixedly installed on the outer surfaces of the two worm wheels 202 will rotate as the worm wheels 202 rotate, thereby driving the moving blocks 204 at the top to move horizontally along the preset slide rails on the base 1. Since the two imaging light screens 103 are respectively arranged on the tops of the two moving blocks 204, by rotating the worm 201, the synchronous adjustment of the positions of the two imaging light screens 103 can be achieved, thereby changing the distance between the light source 101 and the imaging light screen 103, and being able to simulate the imaging situation under different object distances, providing convenience for students to explore the influence of object distance on imaging.

[0031] The matching device 104 includes a fixed disk 401. A circular gear 402 is rotatably installed inside the fixed disk 401. A lens assembly 403 is arranged inside the circular gear 402. A limiter 404 is arranged outside the fixed disk 401.

[0032] The matching device 104 arranged on the front and rear sides is used to demonstrate the combined imaging of lenses. In the fixed disk 401 of the matching device 104, a circular gear 402 can be installed inside it by using a bearing structure to ensure that the circular gear 402 can rotate flexibly and smoothly within the fixed disk 401. The lens assembly 403 arranged inside the circular gear 402 includes five different types of lenses, such as convex lenses, concave lenses, plano-convex lenses, plano-concave lenses, biconvex lenses, etc., and is evenly distributed in a circular pattern around the center of the circular gear 402. The parameters such as the focal length and curvature of these lenses are different, and they can produce diverse optical effects. When it is necessary to replace the lenses for experiments, the limit on the circular gear 402 is released by the limiter 404, and the required lens is rotated to the same axial horizontal plane as the lens one 102. In this way, students can observe the change in the light propagation path and the imaging effect after different lens combinations, simulate the process of multiple lenses working together in actual optical applications, and help students deeply understand the working principle of complex optics.

[0033] The limiter 404 includes a fixed box 405. The fixed box 405 is fixedly installed on the outer side of the fixed disk 401. An activity rod 406 is inserted into the interior of the fixed box 405. A slide plate 407 is fixedly installed on the outer surface of the activity rod 406. A spring 408 is sleeved on the outer surface of the activity rod 406. A tooth 409 adapted to the circular gear 402 is fixedly installed at one end of the activity rod 406.

[0034] The function of the limiter 404 is to reliably limit the circular gear 402 to ensure that the lens to be experimented remains in the adjusted position. When the activity rod 406 is pulled outwards, the activity rod 406 drives the slide plate 407 to slide along the smooth inner wall within the fixed box 405. At this time, the spring 408 is compressed. After the tooth 409 is separated from the circular gear 402, the circular gear 402 can be rotated. After the required lens is rotated to the same axial level as the lens one 102, the activity rod 406 is released. Under the elastic force of the spring 408, the activity rod 406 drives the tooth 409 to re-engage into the tooth groove of the circular gear 402, thereby fixing the circular gear 402 and completing the lens replacement operation.

[0035] The moving component 3 includes a second threaded rod 301. The second threaded rod 301 is rotatably installed inside the front and rear sides of the base 1. A slider 302 that is slidably installed on the inner wall of the base 1 is threadedly connected to the outer surface of the second threaded rod 301.

[0036] The moving component 3 is arranged at the bottom of the matching device 104. The second threaded rod 301 is rotatably installed inside the front and rear sides of the base 1. When the second threaded rod 301 is rotated, the slider 302, which is threadedly connected to the outer surface of the second threaded rod 301 and slidably installed on the inner wall of the base 1 through a slide rail, will move horizontally on the base 1. Since the two fixed disks 401 are respectively arranged on the top of the slider 302, by rotating the second threaded rod 301, the position of the matching device 104 can be adjusted, so that the lens on the lens component 403 to be used can be rotated to the same axial level as the first lens 102, providing more possibilities for students to explore optical phenomena under different lens combination methods, further enriching the diversity and operability of the experiment. When the combined experiment is not required, the matching device 104 is moved outwards and back to its original position through the moving component 3 to avoid blocking the first lens 102.

[0037] During the actual experiment process, students can first synchronously adjust the positions of the two different first lenses 102 and the imaging light screen 103 through the distance adjustment component 2, and observe the imaging effects of different lenses under the same conditions. When combined imaging demonstration is required, the matching device 104 is moved inwards through the moving component 3, and then different lenses are selected to be combined with the first lens 102. By observing the imaging characteristics of different lenses and different lens combinations under the same conditions, students can more deeply and comprehensively understand the optical characteristics of the lenses and the working principle of the lens combination in actual optical applications.

[0038] In summary, for the combined optical mirror device for middle school physics experiments, the lens component 403 inside the circular gear 402 in the matching device 104 includes five different lenses. By operating the stopper 404, it is convenient to select the lens to be used for combined experiments with the first lens 102. Students can observe the changes in the light propagation path and imaging effect after different lens combinations, simulate the working process of multi-lens combination in actual optical applications, solve the problem that the traditional optical mirror device lacks the exploration design of lens combination imaging, and help students understand the working principle of complex optics.

[0039] Furthermore, the distance adjustment component 2 can flexibly and synchronously adjust the positions of the two imaging light screens 103, change the distances between the two light sources 101 and the two imaging light screens 103, and simulate the imaging situations of different lenses under different object distances.
