Description

Technical Field

[0001] The present application relates to the technical field of optical platforms, and in particular to a high-precision optical platform device with multi-position adjustment. Background Art

[0002] Amid the rapid development of modern science and technology, metamaterials have become a research hotspot in numerous fields due to their unique physical properties and broad application prospects. Metamaterials are a class of composite materials that, through artificially designed structures, achieve extraordinary physical properties not possessed by natural materials. Their electromagnetic, acoustic, and mechanical properties can be precisely controlled to meet specific requirements. In the field of optics, metamaterials have demonstrated remarkable potential, enabling the creation of devices with exceptional optical properties and significantly advancing innovation in optical technology.

[0003] However, metamaterials face many challenges in optical experiments and applications. The precise control of light propagation paths, angles, and focal positions in metamaterial optical devices relies on optical platform equipment to provide high-precision, multi-dimensional adjustment capabilities. Currently, conventional optical platform equipment is difficult to meet the adjustment needs in metamaterial research and applications. Most existing platforms can only achieve single-direction or limited-direction adjustment, such as simple horizontal or vertical adjustment, and cannot accurately control optical devices in all directions and at multiple angles. When studying the optical properties of metamaterials, it is often necessary to fine-tune the light source and detector from different angles and heights to obtain comprehensive and accurate data. The limitations of existing platforms have seriously restricted the in-depth development of research.

[0004] Furthermore, metamaterial optical experiments require extremely stable environments; even small vibrations and displacements can significantly affect experimental results. Conventional optical platforms lack stability, making it difficult to provide reliable support for metamaterial optical devices in complex experimental environments. This significantly reduces the accuracy and repeatability of experimental data. For example, when testing the optical transmission characteristics of metamaterials, even the slightest shake of the platform can cause light to deviate from its intended path, resulting in skewed measurement results that fail to truly reflect the metamaterial's optical properties.

[0005] Furthermore, the research, development, and application of metamaterials often involve the coordinated operation of multiple optical instruments, requiring optical platforms with excellent compatibility and scalability to flexibly install and adjust different types of optical components. However, existing optical platforms lack structural flexibility, making it difficult to quickly adapt to the installation and adjustment requirements of new metamaterial optical devices. This increases experimental costs and time, hindering the rapid development and widespread application of metamaterial technology.

[0006] An optical platform is a high-precision optical component support device, mainly used to support optical components and instruments, providing them with a stable and reliable positioning basis.

[0007] Existing platform adjustment brackets for mounting optical components are mostly single-direction adjustable, such as horizontal adjustment or height adjustment, and cannot be adjusted in multiple angles and directions.

[0023] like Figures 1-6 As shown, an embodiment of the present application provides a multi-position adjustable high-precision optical platform device, comprising: The support rods 1 are provided in multiple numbers and can be detachably connected end to end.

The height adjustment member 5 includes a lifting frame 501 slidably mounted on the support rod 1, a fastener 502 is mounted on the lifting frame 501, a marking block 503 is slidably mounted on the support rod 1, and the lifting frame 501 and the marking block 503 are connected by a telescopic ruler 6; The optical fixture 7 is connected to one side of the lifting frame 501 and has an optical instrument 8 detachably connected therein.

The position of the optical fixture 7 can be adjusted more accurately, and the telescopic ruler 6 can be used to intuitively represent the distance moved by the lifting frame 501, so that the subsequent adjustment range can be judged according to the mark, thereby increasing the convenience of the device.

The sliding slot 105 is provided to guide the movement of the marking block 503 and the lifting frame 501, so that they move in the same straight line, thereby ensuring the accuracy of the adjustment.

[0025] like Figure 3 As shown, in some embodiments, the horizontal moving fixture 3 includes a horizontal rail 301 fixedly connected to the top of the mounting frame 201, and a strip groove 302 for the movement of the rotating rod 203 is constructed in the horizontal rail 301 along its length direction, and a positioning bolt 304 that movably passes through the strip groove 302 is connected to the rotating seat 202, and a flip fixture 303 for clamping the edge of the device is detachably connected to one end of the horizontal rail 301. It should be noted that the positioning bolt 304 and the rotating rod 203 can form a two-point positioning to facilitate the linear movement of the rotating seat 202 relative to the horizontal rail 301, thereby adjusting the horizontal position of the support rod 1 on the horizontal rail 301, increasing the adjustable orientation of the device, and improving the adaptability of the device. The flip fixture 303 is provided to adjust the angle of the support rod 1 relative to the flip fixture 303, thereby changing the orientation of the optical fixture 7 in the vertical plane, further increasing the adaptability of the device.

[0026] like Figure 3-Figure 4As shown, in some embodiments, the flip fixture 303 includes a U-shaped plug board 3031 inserted at one end of the horizontal rail 301, the U-shaped plug board 3031 is hinged with an L-shaped vertical plate 3032, the U-shaped plug board 3031 is constructed with a hinge seat 3033, the L-shaped vertical plate 3032 is constructed with a rotating shaft 3034 rotatably installed in the hinge seat 3033, one end of the rotating shaft 3034 is threadedly connected with an adjusting bolt 3035 that abuts on the hinge seat 3033, a movable plate 3036 is slidably installed on the L-shaped vertical plate 3032, and an adjusting screw 3037 that is threaded and penetrates the movable plate 3036 is rotatably installed in the L-shaped vertical plate 3032. The detachable insertion of the U-shaped plug board 3031 and the horizontal rail 301 can realize support The detachable connection between the rod 1 as a whole and the flip clamp 303 facilitates the installation frame 201 to be separated from the flip clamp 303 and connected separately to the platform support plate, thereby increasing the flexibility of the device. Through the cooperation of the L-shaped vertical plate 3032 and the movable plate 3036, the equipment or production line frame can be clamped, thereby fixing the device thereon. By utilizing the cooperation of the hinge seat 3033 and the rotating shaft 3034, the support rod 1 can be rotated vertically relative to the L-shaped vertical plate 3032, and by rotating the adjusting bolt 3035, it can be tightly abutted against the hinge seat 3033, thereby fixing the position after rotation, facilitating the adjustment of the vertical angle change, realizing the change in the orientation of the optical clamp 7, and increasing the adaptability of the device.

[0027] like Figure 4-Figure 5 As shown, in some embodiments, an arc rod 30321 is constructed on one side of the L-shaped vertical plate 3032 and is arranged opposite to the adjusting bolt 3035. An arc groove 30322 is constructed on the arc rod 30321 along its arc line. A fixing screw 30323 that is movable through the arc groove 30322 is threadedly connected to one side of the U-shaped plug plate 3031. By arranging the arc rod 30321 and the fixing screw 30323, the other side of the L-shaped vertical plate 3032 after the angle is changed can be fixed. The fixation on both sides increases the stability of the device after adjustment. At the same time, the arc rod 30321 is used to tightly contact the side of the cross rail 301, so that the position of the U-shaped plug plate 3031 can be fixed, thereby improving the stability of the U-shaped plug plate 3031 connected to the cross rail 301.

[0028] like Figure 4-Figure 5As shown, in some embodiments, the positioning member 4 includes an extension plate 401 constructed on the rotating rod 203, the extension plate 401 movably passes through the rotating seat 202 and is configured with a pushing block 402 at the end, an arcuate surface 403 is configured at one end of the rotating seat 202, and a scale bar 404 is configured on the arcuate surface 403 and located on the side of the pushing block 402, a positioning gear 405 is fixedly sleeved on the rotating rod 203, a connecting plate 406 is configured on the arcuate surface 403, a positioning rod 407 is horizontally slid through the connecting plate 406, a support spring 408 sleeved on the positioning rod 407 is installed between the positioning rod 407 and the connecting plate 406, one end of the positioning rod 407 is configured with a rounded corner and abuts against the tooth groove of the positioning gear 405, when the support rod 1 needs to be angularly adjusted horizontally When adjusting the degree, the push block 402 can be directly moved to drive the extension plate 401 and the rotating rod 203 to rotate. At this time, the tooth groove of the positioning gear 405 will conflict with the arc end of the positioning rod 407, so that the positioning rod 407 is squeezed and moved, and the support spring 408 is compressed, thereby realizing the rotation of the rotating rod 203. When the rotation stops, the positioning rod 407 will automatically rebound due to the elastic force of the support spring 408, and thus be reinserted into another tooth groove, and the positioning is achieved by the resistance force, thereby preventing the support rod 1 from rotating easily and increasing the adjustment stability. It should be noted that the number of tooth grooves of the positioning gear 405 is equal to a multiple of thirty-six, and the scale on the scale bar 404 is equal to the rotation angle of a single tooth groove, so as to clearly indicate the rotation angle and increase convenience.

[0029] like Figure 6-Figure 7 As shown, in some embodiments, the lifting frame 501 includes a rectangular frame 5011 that is sleeved on the support rod 1, and a control nut 5012 is installed at one end of the rectangular frame 5011.

Four rolling wheels 5014 that are rotatably installed in the rectangular frame 5011 and abut against the support rod 1 are used. By utilizing the threaded cooperation between the control nut 5012 and the sliding block 5013, the sliding block 5013 can be tightly abutted against the inner wall of the sliding groove 105, thereby fixing the position of the rectangular frame 5011. The provision of the rolling wheels 5014 facilitates the sliding of the rectangular frame 5011, avoids it from getting stuck due to excessive contact area, and increases convenience.

[0030] like Figure 7-Figure 8As shown, in some embodiments, the marking block 503 includes a moving block 5031 slidably installed in the sliding groove 105, and the moving block 5031 is threadedly connected to a marking screw button 5032 that abuts against the support rod 1. The telescopic ruler 6 includes a shell 601 fixedly connected to the side of the rectangular frame 5011, and a fixed column 602 is constructed in the shell 601. A coil spring 603 is sleeved on the fixed column 602, and the movable end of the coil spring 603 is connected to a tape measure 604 partially wound in the shell 601. One end of the tape measure 604 vertically passes through the shell 601 and the end is connected to the moving block 5031. When the marking block 503 moves, the tape measure 604 will be synchronously driven to extend, thereby intuitively indicating the distance. Then, the lifting frame 501 is moved, and the adjusted distance of the lifting frame 501 can be known by the length of the contraction of the tape measure 604, without the need for increase or decrease calculations, thereby increasing convenience.

[0031] like Figure 7 and Figure 9 As shown, in some embodiments, the optical fixture 7 includes a mounting block 701 connected to one end of the rectangular frame 5011 by bolts, and a circular groove 702 is constructed on the vertical side of the mounting block 701, and a spring contact plate 703 is rotatably installed in the circular groove 702.

A semi-arc groove is formed between the mounting block 701 and the arc-shaped limiting plate 704, which can limit the circular connecting piece 801 and then plug in the optical instrument 8, and the spring contact plate 703 can be used to contact the circular connecting piece 801, thereby increasing the stability after installation.

[0032] like Figure 9As shown, in some embodiments, the spring contact plate 703 includes a limiting disc 7031 rotatably mounted in the circular groove 702, a contact spring 7032 is installed between one side of the limiting disc 7031 and the circular groove 702, and a rotating boss 7033 is constructed on the other side of the limiting disc 7031 and penetrates the circular groove 702. The side of the rotating boss 7033 is connected to a horizontal plate push block 7034, and a contact block 7035 is constructed on the mounting block 701 and is arranged opposite to one end of the arc-shaped limiting plate 704. When the horizontal plate push block 7034 rotates to between the contact block 7035 and the arc-shaped limiting plate 704, the rotating boss 7033 is rotated. It tightly contacts the circular connecting piece 801. It should be noted that the contact block 7035 is set at one end of the semi-arc groove. When the horizontal plate push block 7034 rotates to between the contact block 7035 and the arc-shaped limit plate 704, the rotating boss 7033 tightly contacts the circular connecting piece 801. The contact block 7035 provides a resistance force to the rotating boss 7033, which can increase its resistance force to the circular connecting piece 801, further improving the stability of the installation of the optical instrument 8. When disassembling the optical instrument 8, you only need to rotate the horizontal plate push block 7034 in the opposite direction to disengage it from the contact block 7035. The operation is convenient and quick.
