Description

Technical Field

[0001] This utility model relates to the field of jewelry testing technology, and in particular to a clamping fixture for jewelry testing. Background Technology

[0002] In the field of jewelry testing, the identification of authenticity, quality grading, and determination of craftsmanship defects all rely on the accurate capture of its core characteristics. These include external features such as color uniformity, surface texture integrity, and setting precision, as well as internal clarity characteristics. These characteristics are often subtle and easily affected by observation angle, lighting conditions, and the stability of the jewelry. A deviation in observation can directly lead to misjudgments, such as classifying jewelry with minor cracks as flawless, or mistaking the color and texture of a counterfeit for natural jewelry features, severely impacting the reliability of the test results. Therefore, accurate observation of these characteristics is a core prerequisite for ensuring the quality of jewelry testing.

[0003] In Chinese patent publication CN 219870981U, a jewelry inspection clamping and positioning fixture, while capable of securely holding individual pieces of jewelry to prevent drop and wear through clamping components on both sides of the inspection stage, and improving the clarity of color observation with supplementary lighting components, thus solving the problems of single-piece jewelry clamping protection and basic supplementary lighting, still has significant technical limitations: its clamping components are a single-unit structure adapted to a single stage, which can only fix a single piece of jewelry. In actual testing, when comparing the jewelry to be inspected with standard samples or screening jewelry from the same batch, it is necessary to repeatedly disassemble and clamp multiple pieces of jewelry, increasing the time for a single inspection by 30%. The above-mentioned issues make it easier for inconsistencies in the comparison benchmarks caused by differences in the position and tilt angle of the jewelry held in two separate clamping operations. This makes it difficult to accurately identify subtle features such as deviations in the distribution of colored gemstone bands and differences in the height of the prongs in the setting. The solution does not disclose a fine adjustment mechanism for the clamping spacing, suggesting that it can only be adapted to jewelry of a specific size range. When dealing with jewelry with significant size differences, such as small loose beads or large pendant bodies, it is necessary to change the clamping accessories or manually force adjustments, which is highly complex and prone to causing damage to the surface of the jewelry due to over-adjustment or shaking during testing due to loose clamping, thus limiting its adaptability. Even with the addition of a stage and clamping components, the fixture does not have a relative spacing adjustment mechanism for multiple clamping structures. It cannot adjust the relative positions of multiple pieces of jewelry according to the needs of close comparison of texture details requiring a smaller spacing or observation of overall color differences requiring a larger spacing, further limiting the flexibility and accuracy of comparative observation.

[0004] Therefore, there is an urgent need for a clamping fixture that can flexibly adjust the spacing of multiple clamping structures to meet the needs of comparative observation, and can conveniently adjust the clamping spacing to adapt to jewelry of different sizes. Utility Model Content

Furthermore, the separate design of the fixed arm and the movable arm in the clamping device, combined with the transmission structure of the rotating rod and the lead screw, allows the second clamping seat to be displaced relative to the movable arm by rotating the lead screw, thereby adjusting the clamping distance between the first and second clamping seats. This provides stable clamping of jewelry of different sizes and shapes, and the operation can be completed simply by rotating the lead screw, making it convenient and efficient. This ensures that the jewelry does not easily shake during inspection, further guaranteeing the stability and reliability of the inspection and observation. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-3A clamping fixture for jewelry testing includes a base 1, with support plates 2 at both ends of the upper surface of the base 1, and a receiving plate 3 between the two support plates 2. The receiving plate 3 has a first groove 4 on the side away from the base 1, and two sets of clamping devices 5 are slidably disposed in the first groove 4. The clamping device 5 includes a connecting plate 6, which is slidably connected to the first slide groove 4. A clamping arm 7 is provided on the side of the connecting plate 6 away from the first slide groove 4. The clamping arm 7 is divided into a fixed arm 8 and a movable arm 9. A first clamping seat 10 is provided on the fixed arm 8, and a second clamping seat 11 is provided on the movable arm 9. One end of the second clamping seat 11 is movably connected to a rotating rod 12. The rotating rod 12 passes through the movable arm 9, and a lead screw 13 is rotatably provided inside the rotating rod 12. One end of the lead screw 13 is connected to the second clamping seat 11, and the other end movably passes through the rotating rod 12 and extends outward. Two sets of clamping devices 5 are used to place and compare different pieces of jewelry. The distance between the two sets of clamping devices 5 is controlled by the slide groove to achieve a detailed observation effect. In the example of this application, a first groove 4 is provided on the receiving plate 3, and two sets of clamping devices 5 are slidably configured. The relative distance between the two sets of clamping devices 5 can be flexibly adjusted by the guiding effect of the groove, so as to realize the side-by-side placement and comparative observation of different jewelry. This makes it convenient for inspectors to intuitively compare the color, texture, craftsmanship details and other features of the jewelry, effectively improving the detail and accuracy of the inspection process. At the same time, the separate design of the fixed arm 8 and the moving arm 9 in the clamping device 5, together with the transmission structure of the rotating rod 12 and the lead screw 13, can drive the second clamping seat 11 to move relative to the moving arm 9 by rotating the lead screw 13, thereby adjusting the clamping distance between the first clamping seat 10 and the second clamping seat 11. This can stably clamp jewelry of different sizes and shapes, and the operation can be completed by simply rotating the lead screw 13, which is convenient and efficient, ensuring that the jewelry is not easily shaken during the inspection process, and further ensuring the stability and reliability of the inspection and observation.

[0018] In the example of this application, the first clamping seat 10 includes a protrusion 14, the protrusion 14 is a hollow structure, a fixing block 15 is movably disposed inside the protrusion 14, an elastic element 16 is disposed at one end of the fixing block 15 near the protrusion 14, and the elastic element 16 is connected to the inner wall of the protrusion 14 at the end away from the fixing block 15.

[0019] As a preferred example of this utility model, a movable fixing block 15 is provided within the hollow protrusion 14 of the first clamping seat 10, and an elastic element 16 is used to connect the fixing block 15 to the inner wall of the protrusion 14. This allows the fixing block 15 to adaptively conform to the surfaces of jewelry with different contours and shapes by means of the deformation of the elastic element 16. On the one hand, the buffering effect of the elastic element 16 can avoid damage such as indentations and scratches caused by rigid clamping to the jewelry, effectively protecting the integrity of the jewelry's appearance. On the other hand, the restoring force of the elastic element 16 can keep the fixing block 15 in contact with the jewelry surface, significantly enhancing the clamping stability of irregularly shaped jewelry, preventing the jewelry from shifting during the inspection process due to contour mismatch, and providing a stable clamping basis for subsequent detailed observation.

[0020] In the example of this application, the fixing block 15 is made of conductive material. As a preferred example of this utility model, the fixing block 15 is made of conductive material, which can construct a stable conductive path and provide a reliable electrical connection basis for the lamp body 19. Compared with non-conductive materials, the conductive fixing block 15 can avoid electrical signal interruption or component failure due to poor contact, and ensure the stable operation of the auxiliary detection function that relies on conductivity.

[0021] In the example of this application, a button battery 17 is provided inside the protrusion 14, a contact switch 18 is installed on the button battery 17, and a lamp body 19 is provided at one end of the protrusion 14 near the fixing block 15. The lamp body 19 is electrically connected to the fixing block 15 by triggering the contact switch 18. The contact switch 18 is located on the side of the fixing block 15 away from the lamp body 19 and maintains a triggering distance. Limiting blocks 21 are provided on both sides of the contact switch 18. As a preferred example of this utility model, by integrating a button battery 17, a contact switch 18, and a lamp body 19 within the protrusion 14, and designing a linkage structure whereby the fixing block 15 triggers the contact switch 18, an automatic lighting function is achieved after the jewelry is clamped: when the jewelry is clamped, the jewelry pushes the fixing block 15 to compress the elastic element 16 and move towards the contact switch 18, triggering the contact switch 18 to close, so that the button battery 17 supplies power to the lamp body 19 to light it up, eliminating the need to manually turn on the lighting components and significantly improving the convenience of the inspection operation; the lamp body 19 is located at the end of the protrusion 14 near the fixing block 15, which can directly illuminate the contact area between the jewelry and the clamping seat and the details of the jewelry surface, effectively improving the lighting conditions during inspection and enhancing the clarity of detail observation; at the same time, the limiting blocks 21 on both sides of the contact switch 18 can accurately limit the trigger stroke of the fixing block 15, avoiding excessive displacement of the fixing block 15 that could damage the contact switch 18, or insufficient displacement that could cause the switch not to be triggered, ensuring stable triggering and reliable operation of the lighting function.

[0022] In the example of this application, the fixed arm 8 and the movable arm 9 are each provided with a second slide table 22 on their opposite sides. The second slide table 22 has a sliding clamp holding a sliding plate 23. The sliding plate 23 is provided with a detection light 24. The second slide table 22 is an electric slide table. As a preferred example of this utility model, by opening an electric slide on the opposite side of the fixed arm 8 and the movable arm 9, and setting a sliding plate 23 with a detection lamp 24, the automatic and precise position adjustment of the detection lamp 24 can be achieved: the electric slide can drive the sliding plate 23 to move smoothly along the length of the clamping arm 7, so that the detection lamp 24 can cover different axial areas of the jewelry. The setting of the detection lamp 24 can specifically supplement the local light source required for jewelry detection, and is especially suitable for observing the luster of the jewelry surface, the facet joints and other detailed features, complementing the lamp body 19 and further optimizing the detection light environment.

[0023] In the example of this application, a third groove 25 is provided on the sliding plate 23, and a slider 26 is slidably disposed in the third groove 25. The slider 26 is connected to the detection lamp 24 on the side facing away from the third groove 25. As a preferred example of this utility model, a third slide groove 25 is provided on the sliding plate 23, and a slider 26 with a detection lamp 24 is slidably set there, constructing a dual adjustment structure of the second slide table 22 and the third slide groove 25: the third slide groove 25 can realize secondary fine adjustment of the detection lamp 24 along the length direction of the sliding plate 23, so that the detection lamp 24 can further focus on specific local areas of the jewelry on the basis of electric adjustment, significantly improving the accuracy and targeting of the lighting; the sliding connection between the slider 26 and the detection lamp 24 is flexible in operation, and the inspector can quickly adjust the lamp position according to the real-time inspection needs without starting and stopping the electric slide groove, taking into account both adjustment accuracy and operational efficiency; this structure enables the adjustment range of the detection lamp 24 to cover multiple dimensions, including the whole and local areas, effectively adapting to jewelry of different sizes and different inspection focuses, and broadening the applicable scenarios of the device.

[0024] In the example of this application, baffles 27 are provided on both sides of the support plate 2. The baffles 27 and the support plate 2 together form a storage room 28, which is used to temporarily store jewelry to be tested or jewelry that has been tested.

[0025] As a preferred example of this utility model, by setting baffles 27 on both sides of the support plate 2, a storage room 28 is formed by the support plate 2, providing a nearby and independent storage space for the jewelry to be tested or the jewelry that has been tested: on the one hand, it can avoid the loss or collision damage caused by the jewelry being placed randomly during the testing process, which is especially suitable for batch testing of multiple pieces of jewelry; on the other hand, the storage room 28 is set adjacent to the clamping device 5, which shortens the jewelry picking and placing path, eliminates the need to prepare additional storage containers, and significantly improves the continuity and efficiency of the testing operation.

[0026] In the example of this application, the first clamping seat 10 and the second clamping seat 11 are each provided with an anti-slip pad 20 on their corresponding sides, and the anti-slip pad 20 is made of a flexible material.

[0027] As a preferred example of this utility model, a non-slip pad 20 made of flexible material is provided on the opposite surfaces of the first clamping seat 10 and the second clamping seat 11. This can improve the clamping performance in two ways: First, the flexible material can increase the friction between the clamping seat and the jewelry surface, effectively preventing the jewelry from sliding due to external force or slight shaking during the testing process, and further enhancing the clamping stability; Second, the flexible material has good cushioning properties, which can avoid scratches, indentations and other damage caused by direct contact between the hard surface of the clamping seat and the jewelry, maximizing the protection of the jewelry's appearance quality; In addition, the setting of the non-slip pad 20 does not change the clamping distance adjustment range of the clamping seat, and while improving the clamping reliability and jewelry protection, it does not affect the device's adaptability to jewelry of different sizes.

[0028] 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.
