Description

Technical Field

[0001] This utility model relates to the field of optical imaging technology, and in particular to a desktop optical imaging magnification display device. Background Technology

[0002] Due to the demands of daily life and work, people generally spend a lot of time using their eyes at close range, leading to many sub-health problems. In particular, myopia is becoming increasingly serious among teenagers who are in school. In order to adapt to close-range imaging, the axial length of the eye gradually increases, resulting in myopia.

[0003] A search revealed Chinese patent CN222125523U, which discloses a high-resolution telescope comprising a support unit and a lens mount unit. The lens mount unit is disposed on the support unit and constructs an optical path for obtaining the magnified image at the far side. The lens mount unit includes an eyepiece mount, a pivot, and an objective lens mount. The eyepiece mount is disposed on the support unit and has a reflective lens that is higher than the table and tilted relative to the table. One end of the objective lens mount is disposed on the pivot and can be rotated relative to the eyepiece mount. The objective lens mount has a magnifying lens located above the object.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] While the aforementioned patent can magnify the image, it cannot adjust the height of the imaging device, making it unsuitable for users of different body types and heights, resulting in poor performance and thus having certain limitations. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a desktop optical imaging magnification display device, which can obtain a magnified image with no deformation and high clarity by using two easily processed lenses. It has a simple structure and is easy to use.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a desktop optical imaging magnification display device, including a bracket, a storage cylinder and a limiting slide cylinder are fixedly installed on the surface of the bracket, a threaded rod is slidably installed inside the storage cylinder, and a mounting block is fixedly installed at the end of the threaded rod, and an imaging component is also included.

[0008] The imaging component is mounted on the mounting block.

[0009] The imaging assembly includes a support plate fixedly installed at one end of the mounting block. A pair of damping shafts are symmetrically fixedly installed at the end of the support plate. A connecting block and a pair of connecting blocks are fixedly installed on the outer ring of each damping shaft. A beam splitter is fixedly installed at the bottom of the pair of connecting blocks and a concave mirror is fixedly installed at the bottom of the multiple connecting blocks.

[0010] In some embodiments, a screen is fixedly installed inside the support plate, a damping shaft is fixedly installed between each pair of connecting blocks 2, a connecting block 3 is fixedly installed on the outer ring of each damping shaft 2, and a light shield is fixedly installed on the bottom of a pair of connecting blocks 3.

[0011] In some embodiments, a threaded sleeve is rotatably mounted on the end of the storage tube, and the threaded sleeve is threadedly connected to the threaded rod.

[0012] In some embodiments, an L-shaped limiting rod is fixedly installed on the other side of the mounting block, and the L-shaped limiting rod slides in a sliding engagement with the limiting slide.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this invention magnifies and images objects such as books placed on a table, achieving an imaging effect similar to a telescope. However, compared to a telescope, this device only uses two easily processed lenses to obtain magnified images with low distortion and high clarity. It has a simple structure and is easy to use. At the same time, by adjusting the curvature of the concave mirror surface, it can also obtain high-quality optical magnification images for various special purposes, greatly improving the practicality of the device.

[0015] Secondly, this utility model is not only simple to operate, but also allows for height adjustment according to the height of different users through the threaded rod and threaded sleeve, further improving the convenience and practicality of the device.

[0016] This solves the problem that while existing technologies can magnify images, they cannot adjust the height of the imaging device, making it unsuitable for users of different body types and heights, resulting in poor performance. Attached Figure Description

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved desktop optical imaging magnification display device. The technical solution of this utility model is as follows:

[0027] like Figures 1-5 As shown, a desktop optical imaging magnification display device includes a support 1, a storage cylinder 2 and a limiting slide cylinder 8 fixedly mounted on the surface of the support 1, a threaded rod 4 slidably mounted inside the storage cylinder 2, and a mounting block 5 fixedly mounted at the end of the threaded rod 4. It also includes an imaging component. The height of the imaging component can be adjusted by the threaded rod 4, which improves the practicality of the device. The imaging component can be used to magnify and image objects placed on the desktop.

[0028] The imaging component is mounted on mounting block 5.

[0029] The imaging assembly includes a support plate 6 fixedly mounted on one end of the mounting block 5. A pair of damping pivots 9 are symmetrically fixedly mounted on the end of the support plate 6. A connecting block 10 and a pair of connecting blocks 22 are fixedly mounted on the outer ring of each damping pivot 9. A beam splitter 11 is fixedly mounted on the bottom of the pair of connecting blocks 10. A concave mirror 13 is fixedly mounted on the bottom of the multiple connecting blocks 22. The damping pivots 19 enable the beam splitter 11 and the concave mirror 13 to rotate and fold. Utilizing the characteristics of the damping pivots, the beam splitter 11 and the concave mirror 13 can be adjusted at multiple angles. When not in use, they can be folded and stored for easy storage.

[0030] Furthermore, a screen 17 is fixedly installed inside the support plate 6, and a damping shaft 14 is fixedly installed between each pair of connecting blocks 12. A connecting block 15 is fixedly installed on the outer ring of each damping shaft 14, and a light shield 16 is fixedly installed at the bottom of a pair of connecting blocks 15. The light shield 16 can completely cover the beam splitter 11 and the concave mirror 13, thereby placing the optical elements inside the light shield 16 and shielding them from light to avoid interference from strong external light on imaging.

[0031] Furthermore, a threaded sleeve 3 is rotatably installed at the end of the storage tube 2. The threaded sleeve 3 is threadedly connected to the threaded rod 4. By rotating the threaded sleeve 3, the height of the imaging component can be adjusted using the threaded rod 4, thereby improving the practicality of the device.

[0032] Furthermore, an L-shaped limiting rod 7 is fixedly installed on the other side of the mounting block 5. The L-shaped limiting rod 7 slides with the limiting slide cylinder 8. The L-shaped limiting rod 7 can limit the movement of the imaging component, preventing the threaded sleeve 3 from spinning freely and causing the inability to adjust the height of the imaging component.

[0033] The specific working method is as follows: Place the device on a table, and place the book or other object to be magnified on the same table, below the device. Rotate the beam splitter 11 to a 45° angle with the viewing axis. The beam splitter 11 is equipped with a film with a predetermined transmission-to-reflection ratio. Use a beam splitter film with a transmission-to-reflection ratio of 5:5. Rotate the concave mirror 13 to a 45° angle with the beam splitter 11. The radius of curvature of the concave mirror 13 ranges from 350mm to 1500mm. The surface shape of the concave mirror 13 is spherical, aspherical, or freeform. At this time, the light reflected from the imaging object is directed towards the beam splitter 11 from below, and the beam splitter 11 directs a portion of the light onto the screen 17. A portion of the light passes through and is directed towards the concave mirror 13, which then reflects the light back to the beam splitter 11, and finally to the human eye. At this point, the human eye will see a magnified image of the object based on the curvature of the concave mirror 13. Furthermore, a total reflection film or a beam splitter with a predetermined transmission-to-reflection ratio is attached to the concave mirror 13. When a total reflection film is provided on the concave mirror 13, the desktop far-view reading and writing device can achieve a display similar to virtual reality. When a beam splitter with a predetermined transmission-to-reflection ratio is provided on the concave mirror 13, the desktop optical imaging magnification display device can achieve an augmented reality display with optical perspective, and ambient light can enter the human eye through the first concave mirror 13 and the beam splitter 11.

[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
