Description

Technical Field

[0001] This utility model relates to the field of optical experimental technology, and in particular to an optical experimental stand. Background Technology

[0002] In the field of optical experiments, optical platforms and their associated magnetic bases and adjustment frames are the core basic equipment for building optical paths. However, the traditional optical experimental rigs currently in widespread use have the following significant drawbacks: First, traditional methods for component installation and fixation suffer from inefficiency and lack of standardization. Existing optical adjustment frames and platforms lack a unified, intelligent, and rapid installation mechanism. Researchers must manually perform tedious initial positioning, precise alignment, and tightening operations; the entire process is time-consuming, labor-intensive, and heavily reliant on the operator's experience, making it difficult to guarantee reproducibility for each installation. Furthermore, functional components (such as light sources) are often independent devices, fixed by multiple separate brackets. This not only occupies valuable platform space but also increases the complexity of optical path alignment, hindering rapid deployment and modular reconfiguration of experiments.

[0003] Secondly, regarding the adsorption and fixation of magnetic bases, there are problems such as easy damage to the platform surface and inconvenience in adjustment. Currently, most mainstream magnetic bases use a switch-type or simple mechanical translation structure to change the distance between the magnet and the platform. Their adsorption force is either not adjustable or has a limited and non-linear adjustment range. This leads to two common problems: first, using excessive suction force to avoid slippage easily scratches the delicate and expensive optical platform surface on the hard bottom of the magnetic base; second, reducing the suction force for ease of movement risks insecure fixation and optical path misalignment due to slight vibrations. This contradiction seriously affects the stability of experiments and the lifespan of the platform. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an optical experimental frame, which aims to improve the problem of the lack of a unified, intelligent and rapid installation mechanism for the interface between the optical adjustment frame and the platform in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an optical experimental stand, comprising an optical platform and optical components fixed thereon by a magnetic base, wherein the magnetic base is an adjustable magnetic adsorption mechanism, comprising a housing and a magnetic suction body disposed inside the housing, the magnetic base sliding outside the optical platform, the optical platform having an internal cavity, the internal cavity having an adjustable force component, and the optical components being connected to the magnetic base via a quick-connect interface structure, the quick-connect interface structure being used for quickly assembling different optical components.

[0006] As a further description of the above technical solution: The force adjustment component includes a permanent magnet disposed in the upper part of the built-in cavity, a magnetic guide slider is provided at the bottom of the optical platform, and an adjustment latch connected to the magnetic guide slider and extending out of the optical platform.

[0007] As a further description of the above technical solution: A rubber pad is provided in the middle of the outer wall of the adjusting slider.

[0008] As a further description of the above technical solution: The quick-connect interface structure includes a positioning seat, which is installed on top of the magnetic base. Its interior, from top to bottom, consists of a positioning part and a locking part. The positioning part is used to achieve automatic alignment during connection, and the locking part is used to achieve mechanical locking after connection.

[0009] As a further description of the above technical solution: The positioning part includes a positioning port and a rotating shaft arranged around the positioning port. The positioning port is located on the top of the positioning seat. An extension plate is installed on the outer side of the rotating shaft, and a torsion spring is wound around the outside of the rotating shaft.

[0010] As a further description of the above technical solution: The locking part includes a fixed shaft and a positioning plate that slides inside the fixed shaft. The fixed shaft is evenly arranged around the lower part of the inner wall of the positioning seat. The positioning plate and the inner wall of the positioning seat are connected by a spring.

[0011] As a further description of the above technical solution: A light source emitter is installed inside the quick-installation interface structure at one end.

[0012] This utility model has the following beneficial effects: In this invention, by deeply integrating functional modules such as the light source emitter with the quick-installation interface structure, and cooperating with positioning and locking parts that have automatic centering and mechanical locking functions, true "plug-and-play" functionality for optical components is achieved. This not only shortens the time for setting up and reconstructing experimental optical paths, but also strongly supports the standardization and modularization of experimental procedures, improving the efficiency and repeatability of optical experiments.

[0013] In this invention, the core component of the force adjustment assembly is built into the optical platform, allowing for stepless adjustment of the magnetic base's adsorption force through a simple external sliding operation. This design achieves precise control of the adsorption force, ensuring the magnetic base is both firmly fixed and easy to move. Furthermore, it fundamentally avoids the risk of scratching the surface of the precision platform due to excessive or uneven magnetic force, effectively protecting the expensive optical platform and extending its service life.

[0016] 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.

[0017] Reference Figure 1-3 The present invention provides an embodiment of an optical experimental stand, comprising an optical platform 1 and optical components fixed thereon by a magnetic base 2. The magnetic base 2 is an adjustable magnetic adsorption mechanism, comprising a housing 201 and a magnetic suction body 202 disposed inside the housing 201. The magnetic base 2 slides outside the optical platform 1. An internal cavity 101 is provided inside the optical platform 1. An adjustable force component 3 is provided inside the internal cavity 101. The optical components and the magnetic base 2 are connected by a quick-connect interface structure 4. The quick-connect interface structure 4 is used for quick assembly of different optical components.

[0018] The light source emitter 7 is installed inside the quick-connect interface structure 4 at one end.

[0019] The force adjustment component 3 includes a permanent magnet 301 disposed in the upper part of the built-in cavity 101, a magnetic guide slider 302 disposed at the bottom of the optical platform 1, and an adjustment latch 303 connected to the magnetic guide slider 302 and extending out of the optical platform 1.

[0020] A rubber pad 304 is provided in the middle of the outer wall of the adjusting slide buckle 303.

[0021] Specifically, the attraction force is adjusted by changing the magnetic circuit distribution. The permanent magnet 301 generates a fixed magnetic field. When the user moves the adjustment slider 303, it moves the magnetically guided slider 302 at the bottom of the optical platform 1. The magnetically guided slider 302, acting as a movable low-magnetic-resistance path, captures and diverts most of the magnetic field lines when aligned with the outer shell 201 of the upper magnetic base 2, maximizing the attraction force of the magnetic base 2. When the magnetically guided slider 302 moves away, the magnetic circuit is interrupted by a high-magnetic-resistance air gap, drastically reducing the magnetic flux to the magnetic base 2, thus minimizing the attraction force and achieving stepless adjustment. The rubber pad 304 primarily increases friction and provides cushioning. Its high coefficient of friction prevents slippage when the user moves the adjustment slider 303. Simultaneously, the elastic properties of the rubber absorb some vibrations and provide cushioning protection on the contact surface between the adjustment slider 303 and the optical platform 1, preventing wear and noise that may result from hard metal contact.

[0022] The quick-connect interface structure 4 includes a positioning seat 401, which is installed on the top of the magnetic seat 2. Its interior, from top to bottom, consists of a positioning part 5 and a locking part 6. The positioning part 5 is used to achieve automatic alignment during connection, and the locking part 6 is used to achieve mechanical locking after connection.

[0023] The positioning part 5 includes a positioning port 501 and a rotating shaft 502 arranged around the positioning port 501. The positioning port 501 is opened on the top of the positioning seat 401. An extension plate 503 is installed on the outer side of the rotating shaft 502, and a torsion spring 504 is wound around the outside of the rotating shaft 502.

[0024] The locking part 6 includes a fixed shaft 601 and a positioning plate 602 that slides inside the fixed shaft 601. The fixed shaft 601 is evenly arranged around the lower part of the inner wall of the positioning seat 401. The positioning plate 602 and the inner wall of the positioning seat 401 are connected by a spring 603.

[0025] Specifically, when installing the optical component, the connecting structure at its bottom is first inserted into the positioning part 5, which automatically completes initial positioning and centering. Subsequently, as the component continues to be pressed down, the locking part 6 is triggered, and the component is firmly locked in the positioning seat 401 through a mechanical structure, ensuring absolute stability during the experiment. The positioning opening 501 is conical, utilizing its geometric characteristics to achieve automatic centering. When the connecting post of the optical component is inserted, even with slight deviations, it can slide towards the center guided by the conical surface. In its natural state, the force of the torsion spring 504 causes the extension plate 503 to partially cover the bottom of the positioning opening 501, preventing the component from accidentally falling off. When the component is inserted, the extension plate 503 is pushed open to smoothly enter the self-locking mechanism based on the inclined surface. The inner side of the positioning plate 602 is usually designed with an inclined surface. When the connecting post of the optical component has completely passed through the positioning part 5 and continues to be pressed down, the locking groove or flange at its bottom will squeeze the inclined surface of the positioning plate 602, forcing the positioning plate 602 to overcome the elastic force of the spring 603 and slide outward along the fixed axis 601. When the connecting post reaches its final position, the locking groove is aligned with the positioning plate 602. At this time, the restoring force of the spring 603 will quickly push the positioning plate 602 to reset inward, and its front end will be inserted into the locking groove to form a mechanical interlock, which will firmly lock the optical component in the designated position and effectively resist vibration and impact.

[0026] Working principle: The user first moves the magnetic base 2 to the target position on the optical platform 1 by sliding the magnetic base 2. Then, by adjusting the sliding buckle 303, the user drives the magnetic guide slider 302 at the bottom of the optical platform 1 to move, thereby changing the magnetic circuit distribution generated by the built-in permanent magnet 301. When the magnetic guide slider 302 is aligned with the magnetic base 2, a low magnetic resistance path is formed, which maximizes the attraction force. When the magnetic guide slider 302 is moved away, the magnetic circuit is interrupted, which weakens the attraction force. This achieves stepless adjustment and fixation of the attraction force of the magnetic base 2. The rubber pad 304 on the adjusting buckle 303 ensures anti-slip and cushioning during operation. After the magnetic base 2 is fixed, the optical component is installed through the quick-release interface structure 4 on its top. During installation, the connecting post at the bottom of the component is first inserted into the positioning port 501 at the top of the positioning base 401. Its conical structure achieves automatic centering and pushes open the normally closed gate mechanism composed of the rotating shaft 502, torsion spring 504, and extension plate 503 to move downward. When the component continues to be pressed down to the working position, it will squeeze the inclined surface of the positioning plate 602 in the locking part 6, causing it to overcome the elastic force of the spring 603 and slide outward along the fixed shaft 601. After the component is in place, the positioning plate 602 quickly snaps into the locking groove of the component under the action of the spring 603, completing the mechanical locking and realizing the rapid, accurate, and stable installation of the optical component. In addition, the light source emitter 7 integrated inside the quick-release interface structure 4 can be used as a standardized functional module and directly connected to the optical path.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
