Description

Technical Field

[0001] This utility model relates to an imaging device, and more particularly to an optical imaging device for physics. Background Technology

[0002] In current physics optics teaching, traditional teaching aids present significant limitations in teaching effectiveness. During lectures on optical principles, instructors often need to simultaneously operate experimental equipment, draw optical path diagrams, and write formula derivations, resulting in fragmented class time. Students' attention is forced to frequently switch between blackboard text and experimental devices, making it difficult to form a systematic understanding of the concepts. This teaching model, separating teaching aids from blackboard writing, not only occupies a large amount of blackboard space but also makes it difficult to present abstract optical phenomena synchronously with theoretical explanations, severely impacting students' intuitive understanding of core concepts such as wave optics and imaging principles.

[0003] Existing optical teaching aids suffer from three main inherent drawbacks: First, fixed experimental tables occupy classroom space and cannot spatially correspond with blackboard content, easily obstructing students' view during demonstrations; second, discrete optical components are cumbersome to adjust and cannot achieve real-time linkage between optical path parameters and blackboard theory; third, traditional projection equipment is independent of the blackboard area, resulting in a spatial disconnect between experimental phenomena, formula derivations, and diagrams, requiring students to repeatedly switch focus points. This physical separation between teaching aids and teaching media directly restricts the efficiency of information transmission and the effectiveness of knowledge construction in classroom teaching. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an optical imaging device for physics.

[0005] The technical solution is as follows: An optical imaging device for physics includes a connecting seat, a guide seat, a slide rail, a magnetic block, a slide base, a guide rod, and a sliding block. The connecting seat has symmetrically arranged guide seats on both sides. Each guide seat has a slide rail. Both the guide seats and the connecting seat have magnetic blocks at their rear for attaching to a blackboard. Each slide rail has at least one slide base that slides on it. Each sliding block has a vertically arranged guide rod. Each guide rod has a sliding block that slides on it. Each sliding block has a tightening block screwed inside it. The inward end of each tightening block abuts against the guide rod. The tightening block is used to fix the position of the sliding block on the guide rod. Each sliding block has an adjusting clamp for mounting the components required for optical imaging.

[0006] Furthermore, the guide seats are all hinged to the fixed seat. By rotating the two guide seats until they are parallel to the connecting seat, the guide seats can be rotated and folded. The guide rods are all rotatably mounted on the slide, and there are tightening screws at the rotation axis points of the guide rods and the slide. The tightening screws are used to fix the rotation angle of the guide rods on the slide. The rotation and folding function of the guide rods can be achieved by loosening or unloosening the tightening screws. After folding, the guide rods are close to the surface of the slide rail.

[0007] Furthermore, the adjusting clamp includes a semi-circular guide rail, a rotating block, a scale, a clamping seat, and a clamping block. Each sliding block is rotatably equipped with a semi-circular guide rail, which has a semi-circular groove. A clamping seat is slidably mounted within each semi-circular groove. Each semi-circular guide rail has a scale, and a rotating block is rotatably mounted at the rotation axis of the semi-circular guide rail. Each rotating block has an indicator block pointing towards the scale line on the scale. The other end of the rotating block is connected to the clamping seat on the same semi-circular guide rail. When the clamping seat rotates along the semi-circular slider, the indicator block on the rotating block rotates synchronously, pointing to the corresponding angle scale on the scale. Each clamping seat is elastically connected to a clamping block via an elastic element. The clamping seat has a fixed block opposite to the clamping block. The force of the elastic element on the clamping block pulls the clamping block towards the fixed block on the same clamping seat. Through the cooperation of the clamping block and the clamping seat, elastic clamping of the object is achieved.

[0008] Furthermore, it also includes a carrying case and a base. The carrying case consists of a case body and a rotating lid. The lower part of the case body is equipped with a base, which has multiple slots for holding an optical element. The case body also has a cavity for accommodating the folded device as a whole.

[0009] Furthermore, it also includes rubber blocks, with rubber blocks provided on the same side of the guide seat and the magnetic block.

[0010] Furthermore, it also includes pads extending outward from the lower part of the connecting seat and the lower part of the guide seat.

[0011] Beneficial effects: 1. By setting up an optical imaging device that can be attached to the blackboard, this utility model can intuitively present experimental phenomena and dynamic data changes on the blackboard through the adjustment of high-definition optical components during experimental demonstrations. This assists operators in explaining the principles and can project relevant knowledge points, extended materials, or diagrams in real time in conjunction with the blackboard content, forming a rich and colorful teaching picture. This not only saves blackboard space but also allows students to quickly establish knowledge connections, achieving an efficient integration of experimental visualization and three-dimensional blackboard writing, and significantly improving the efficiency of knowledge transmission in classroom teaching.

[0012] 2. This utility model features a foldable design for each part of the device, along with a matching carrying case. When storing the device, the original large size can be quickly folded into a compact form, saving storage space and making it easy to carry when going out. During use, the teaching aid can be quickly restored to its complete form simply by unfolding the folded parts. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] An optical imaging device for physics, such as Figure 1-5As shown, the device includes a connecting seat 1, a guide seat 2, a slide rail 21, a magnetic block 3, a slide 4, a guide rod 5, and a sliding block 51. The connecting seat 1 has symmetrically arranged guide seats 2, each guide seat 2 having a slide rail 21. Each slide rail 21 has at least two slides 4. The slides 4 slide smoothly on the slide rail 21 without jamming. Both the guide seat 2 and the connecting seat 1 have magnetic blocks 3 at their rear ends. The magnetic blocks 3 are embedded in the grooves of the guide seat 2 and the connecting seat 1, with their surfaces flush with the rear ends of the guide seat 2 and the connecting seat 1, for attaching to the blackboard. The device is quickly fixed and disassembled using magnetic force. Each slide rail 21 has at least one sliding block 51. The base 4 and the slide 4 can slide freely along the slide rail 21. Each sliding block 51 is vertically provided with a guide rod 5, and each guide rod 5 is slidably provided with a sliding block 51. Each sliding block 51 has a through hole that matches the outer diameter of the guide rod 5. The inner wall of the through hole is provided with anti-slip texture. Each sliding block 51 is screwed with a tightening block. The inward end of each tightening block abuts against the guide rod 5. The tightening block is used to fix the position of the sliding block 51 on the guide rod 5. By rotating the tightening block, its end presses against the guide rod 5, and the sliding block 51 is fixed by friction. Each sliding block 51 is provided with an adjustment clamp. The components required for optical imaging, such as light source, lens, prism and screen, are installed by adjusting the clamp.

[0022] The guide seats 2 are hinged to the fixed seat. By rotating the two guide seats 2 until they are parallel to the connecting seat 1, the guide seats 2 can be rotated and folded. During the folding process, the guide seats 2 rotate upward around the hinge axis until they are in contact with the upper surface of the connecting seat 1. At this time, the whole device is easy to store and carry. The guide rods 5 are rotatably mounted on the slide 4. The rotation axis points of the guide rods 5 and the slide 4 are provided with tightening screws. The tightening screws pass through the rotation axis points of the guide rods 5 and the slide 4 and are threadedly connected to the nuts. The tightening screws are used to fix the rotation angle of the guide rods 5 on the slide 4. The rotation and folding function of the guide rods 5 can be achieved by tightening or loosening the tightening screws. After folding, the guide rods 5 are close to the surface of the slide rail 21. When it is necessary to fold the guide rods 5, loosen the tightening screws, rotate the guide rods 5 around the rotation axis points to a position parallel to the slide rail 21, and then tighten the tightening screws again to keep the guide rods 5 in the folded state.

[0023] Specifically, such as Figure 3As shown, the adjusting clamp includes a semi-circular guide rail 6, a rotating block 61, a scale dial 62, a retainer 63, and a retaining block 64. The semi-circular guide rail 6 is rotatably mounted on each sliding block 51. The central axis of the semi-circular guide rail 6 coincides with the rotation axis of the sliding block 51, allowing the semi-circular guide rail 6 to rotate in a vertical plane. A semi-circular groove is provided on the semi-circular guide rail 6, and a retaining block 63 is slidably mounted within each semi-circular groove. The bottom of the retaining block 63 has a slider adapted to the semi-circular groove, ensuring that the retaining block 63 can slide freely along the semi-circular groove. A scale dial 62 is provided on each semi-circular guide rail 6. The scale dial 62 is etched onto the surface of the semi-circular guide rail 6, resulting in clear and wear-resistant graduations. A rotating block 61 is rotatably mounted at each rotation axis point of the semi-circular guide rail 6. The rotating block 61 is fitted onto the rotation axis of the semi-circular guide rail 6 and can rotate freely around the rotation axis. Each rotating block 61 has... There is an indicator block facing the scale line on the dial 62. The indicator block is made of thin metal sheet, and its tip is aligned with the scale line on the dial 62. The other end of the rotating block 61 is connected to the card holder 63 on the same semi-circular guide rail 6. When the card holder 63 rotates along the semi-circular slider, the indicator block on the rotating block 61 rotates synchronously, pointing to the corresponding angle scale on the dial 62. By observing the scale indicated by the indicator block, the rotation angle of the card holder 63 can be accurately determined. Each card holder 63 is elastically connected to a card block 64 by an elastic element. The elastic element is a helical spring, one end of which is fixed on the card holder 63 and the other end is connected to the card block 64. The card holder 63 is provided with a fixed block opposite to the position of the card block 64. The force of the elastic element on the card block 64 pulls the card block 64 toward the fixed block on the same card holder 63. Through the cooperation of the card block 64 and the card holder 63, the object is elastically clamped. When it is necessary to clamp the optical element, pull the locking block 64 outward to increase the distance between the locking block 64 and the fixing block, place the optical element between the locking block 64 and the fixing block, and then release the locking block 64. Under the action of the elastic element, the locking block 64 moves towards the fixing block, thereby clamping the optical element. The elastic clamping method can avoid damage to the optical element and ensure the stable fixation of the optical element.

[0024] During the experimental preparation phase, operators can adjust the positions of each component according to specific experimental needs: loosen the locking knob between the slide block 4 and the slide rail 21, allowing the slide block 4 to slide horizontally along the slide rail 21 to determine the lateral position of the optical element; loosen the tightening block inside the sliding block 51, allowing it to slide up and down along the guide rod 5 to adjust the height of the optical element; rotate the guide rod 5 and fix the angle by tightening the screw to achieve the pitch adjustment of the optical element. Through these three adjustments, various experimental optical paths, such as convex lens imaging and verification of the law of refraction of light, can be quickly constructed.

[0025] Regarding precise angle adjustment, when the angle of the optical element needs to be adjusted, rotating the semi-annular guide rail 6 allows for a wide range of coarse angle adjustments, while sliding the cassette 63 along the semi-annular groove allows for a small range of fine angle adjustments. Because the rotating block 61 and the cassette 63 move synchronously, the position of the indicator block on the dial 62 displays the current angle in real time, ensuring accurate angle adjustment. For example, in experiments verifying the law of reflection of light, this mechanism can be used to accurately measure the relationship between the angle of incidence and the angle of reflection.

[0026] The elastic clamping mechanism uses a combination of a locking block 64 and a fixing block. When the locking block 64 is pulled outward, the elastic element is stretched and generates a rebound force. After the optical element is inserted, the locking block 64 is released, and the rebound force causes the locking block 64 to press the element tightly, which not only ensures stable clamping but also avoids damage to the glass element. This allows optical elements of different specifications, such as light sources, lenses, prisms, and screens, to be installed and removed quickly.

[0027] After the experiment, the device’s folding and storage mechanism came into play: first, the guide rod 5 was rotated around the slide 4 to a position parallel to the slide rail 21 and locked by tightening the screw; then the guide seat 2 was rotated around the hinge axis to a position parallel to the connecting seat 1. At this time, the thickness of the entire device was greatly reduced, making it easy to carry and store. This foldable design effectively solved the problems of traditional optical teaching aids taking up a lot of space and being inconvenient to transport.

[0028] In addition, such as Figure 4 and Figure 5 As shown, to facilitate the storage of the device and optical components, this utility model also includes a carrying case 7 and a bottom pad 71. The carrying case 7 is composed of a case body and a rotating lid hinged together. The lid edge is equipped with a latch to engage with the case body, ensuring the items inside remain securely in place during storage. The bottom pad 71, located at the bottom of the case body, is fixed to the bottom of the case body with strong adhesive. The bottom pad 71 is made of cushioning sponge material and has multiple recesses adapted to the shape of the optical components. Each recess is used to hold one optical component. These recesses not only precisely secure the components, preventing them from shaking and colliding inside the case, but also protect the optical components through the soft sponge material. The case body has a specially designed cavity whose size matches the overall dimensions of the folded device. The folded guide seat 2, slide rail 21, and other components are sequentially stored in the cavity, achieving integrated storage of the device and optical components, facilitating the carrying and transfer of the device.

[0029] Among them, such as Figure 2As shown, to enhance the stability of the device on the blackboard, rubber blocks 22 are installed on the same side of the guide seat 2 and the magnetic block 3. The rubber blocks 22 are embedded in the side of the guide seat 2 through a dovetail groove structure, and their surfaces are frosted to increase roughness. When the magnetic block 3 attaches the device to the blackboard, the rubber blocks 22 will fit tightly against the surface of the blackboard. By utilizing the elasticity and rough surface of the rubber itself, the friction between the rubber and the blackboard is increased. Even during frequent adjustments of the optical components, the device can be effectively prevented from slipping, ensuring the safe and stable conduct of the experimental demonstration.

[0030] Finally, as Figure 1 and Figure 2 As shown, considering the requirements for using the device on desktops and other platforms, outwardly extending pads are provided at the lower part of the connecting seat 1 and the lower part of the guide seat 2. These pads are integrally mounted on the connecting seat 1 and guide seat 2, and their bottoms are made of flat and wear-resistant hard plastic. When the device needs to be placed on a flat surface for experimental operations, these pads provide support, keeping the device stable and preventing it from tipping over due to an unstable center of gravity. The hard plastic material also prevents the pads from wearing down during use, extending the device's lifespan and providing reliable support for diverse teaching scenarios.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
