Description

Technical Field

[0001] This utility model relates to the field of gemstone testing technology, specifically a popular science demonstration device for the luminescence of gemstones. Background Technology

[0002] Ultraviolet light is widely used in the study of the luminescence effect of substances. Ultraviolet lamps, which detect the fluorescence characteristics of gemstones under ultraviolet light, are one of the important instruments for gemstone identification. They can assist in identifying certain gemstone varieties and quickly distinguish between gemstones with similar colors, such as rubies and red garnets.

[0003] Some gemstones emit visible light when excited by ultraviolet light radiation; this is called ultraviolet fluorescence. Different gemstone varieties, and even different samples of the same variety, exhibit different fluorescence reactions due to differences in their constituent elements or trace impurities, displaying different fluorescent colors and intensities. Fluorescence intensity can be categorized into four levels: strong, medium, weak, and none.

[0004] A gemstone identification ultraviolet lamp mainly consists of a light source, a dark chamber, and an observation window. The light source is mounted at the top of the chamber, with two tubes emitting long-wave (365nm) and short-wave (253.7nm) ultraviolet light respectively. Two special filters are installed below the tubes (allowing only 365nm and 253.7nm ultraviolet light to pass through), filtering out stray light. The sample chamber is a dark chamber, with black walls and bottom to avoid reflections affecting observation. The observation window is lined with plexiglass, and some windows are usually fitted with black leather eye shields. The ultraviolet light is controlled by a switch, providing long-wave (365nm) and short-wave (253.7nm) ultraviolet light respectively.

[0005] The fluorescence properties of gemstones under long-wave ultraviolet light and short-wave ultraviolet light can help in gemstone identification.

[0006] Existing ultraviolet fluorescence instruments require the operator to bend over and bring their eyes close to the observation window to observe the luminescence of gemstones, making it inconvenient to obtain luminescence photographs or directly display them to the public. With the increasing emphasis placed on science popularization by the government, jewelry and jade quality inspection institutions, while conducting quality inspection work, also undertake public science popularization work. It is particularly important to enable the public to understand some identification characteristics and methods of jewelry and jade through the luminescence of gemstones, thereby enhancing public awareness and interest, and achieving the goal of science popularization. Ensuring that science popularization work is truly implemented is therefore crucial.

[0007] Therefore, this utility model provides a popular science demonstration device for the luminescence of gemstones to solve the above problems. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] This utility model provides a popular science demonstration device for the luminescence of gemstones, aiming to solve the problems mentioned in the background art.

[0010] (II) Technical Solution

[0012] As a preferred technical solution of this application, the mounting bracket has a mounting groove, both bidirectional lead screws are rotatably connected in the mounting groove, and multiple sliders are slidably connected in the mounting groove, with the sliders threadedly connected to the bidirectional lead screws.

[0013] As a preferred technical solution of this application, a connecting plate is symmetrically fixed on the mounting plate, and a plurality of telescopic rods are fixedly connected between the connecting plate and the limiting plate. Each of the plurality of telescopic rods is fitted with a spring, and the two ends of the spring are fixedly connected to the connecting plate and the limiting plate respectively.

[0014] As a preferred technical solution of this application, the end of the limiting plate is rotatably connected to a guide plate, the connecting plate has a movable groove, the side wall of the movable groove has symmetrical sliding grooves, the side wall of the guide plate has symmetrically fixed movable blocks, and the movable blocks are movably connected in the sliding grooves.

[0026] 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.

[0027] This utility model provides a popular science demonstration device for the luminescence of gemstones, such as... Figures 1-5As shown, the technical solution includes a sample chamber 1 and an ultraviolet lamp 5. A camera 3 is installed on the top of the sample chamber 1, and a laptop computer 2 is installed on one side of the sample chamber 1. The laptop computer 2 is connected to the camera 3 via a data cable 4. A mounting bracket 6 is fixedly connected to the side wall of the sample chamber 1. By setting the camera 3 to transmit the luminescence phenomenon of the gemstone to the display screen of the laptop computer 2, the luminescence of the gemstone can be directly observed on the computer screen, which can more intuitively display the fluorescence phenomenon of the gemstone, bring a better experience to the popular science audience, and is conducive to the promotion of popular science work.

[0028] The mounting bracket 6 is equipped with a fixing mechanism for fixing the ultraviolet lamp 5. The fixing mechanism includes two bidirectional lead screws 8, a mounting plate 9, and sliders 11 and limiting plates 15 symmetrically arranged on the mounting plate 9. Multiple positioning blocks 10 are fixedly connected to the mounting plate 9, and sliders 11 are symmetrically fixed on both sides of the mounting plate 9. The fixing mechanism fixes and limits the ultraviolet lamp 5, making the installation and removal of the ultraviolet lamp 5 simpler and more convenient. When selecting the ultraviolet lamp 5, it can be removed from the existing ultraviolet fluorescence instrument and installed in the sample chamber 1 for use, which is low cost.

[0029] The mounting bracket 6 has a mounting groove, and two bidirectional lead screws 8 are rotatably connected in the mounting groove. Multiple sliders 11 are slidably connected in the mounting groove, and the sliders 11 are threadedly connected to the bidirectional lead screws 8. A connecting plate 14 is symmetrically fixed on the mounting plate 9. Multiple telescopic rods 16 are fixedly connected between the connecting plate 14 and the limiting plate 15. A spring 17 is sleeved on each of the multiple telescopic rods 16, and the two ends of the spring 17 are fixedly connected to the connecting plate 14 and the limiting plate 15 respectively. The telescopic rods 16 guide the extension and retraction of the spring 17 to prevent the spring 17 from bending when compressed, so as not to affect the spring 17's reset ability. A guide plate 18 is rotatably connected to the end of the limiting plate 15. A movable groove is opened in the connecting plate 14. A sliding groove 20 is symmetrically opened on the side wall of the movable groove. A movable block 19 is symmetrically fixed on the side wall of the guide plate 18, and the movable block 19 is movably connected in the sliding groove 20.

[0030] When the fixing mechanism clamps and fixes the UV lamp 5, the mounting plate 9 drives the positioning block 10 to move in opposite directions to fix and clamp the UV lamp 5. During this process, the limiting plate 15 moves to both sides of the UV lamp 5 under the action of the guide plate 18. With the reset ability of the spring 17, the limiting plate 15 is pushed to abut against the side wall of the UV lamp 5, thereby fixing the UV lamp 5 to the side wall of the sample chamber 1 and improving the stability of the UV lamp 5 installation.

[0031] Two bidirectional lead screws 8 are coaxially fixed with pulleys 12, and a transmission belt 13 is connected between the two pulleys 12. A bevel gear set 21 is rotatably connected in the mounting slot. The bevel gear set 21 includes two meshing bevel gears, one of which is coaxially fixed with the bidirectional lead screw 8. A knob 7 is rotatably connected to the side wall of the mounting bracket 6, and the knob 7 is coaxially fixed with the other bevel gear. When in use, rotating the knob 7 drives the bidirectional lead screw 8 to rotate through the bevel gear set 21. The rotating bidirectional lead screw 8 drives the other bidirectional lead screw 8 to rotate through the pulleys 12 and the transmission belt 13. The synchronously rotating bidirectional lead screw 8 drives multiple sliders 11 to move in opposite directions, which in turn drives the two mounting plates 9 to move in opposite directions. The ultraviolet lamp 5 is fixedly clamped by the positioning block 10 on the mounting plate 9. Reversing the knob 7 can release the clamping limit of the ultraviolet lamp 5 by the positioning block 10 on the mounting plate 9, making the disassembly and assembly of the ultraviolet lamp 5 simpler and more convenient.

[0032] In summary: During operation, the UV lamp 5 from the existing UV fluorescence instrument is removed and installed in the sample chamber 1. Rotating the knob 7 drives the bidirectional lead screw 8 to rotate via the bevel gear set 21. The rotating bidirectional lead screw 8 drives another bidirectional lead screw 8 to rotate via the pulley 12 and the transmission belt 13. The synchronously rotating bidirectional lead screw 8 drives multiple sliders 11 to move in opposite directions, which in turn drives two mounting plates 9 to move in opposite directions. The UV lamp 5 is fixedly clamped by the positioning block 10 on the mounting plate 9. During the clamping process, the limiting plate 15 moves to both sides of the UV lamp 5 under the action of the guide plate 18. With the reset ability of the spring 17, the limiting plate 15 is pushed to abut against the side wall of the UV lamp 5, thereby fixing the UV lamp 5 to the side wall of the sample chamber 1.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
