Description

Technical Field

[0001] This utility model belongs to the technical field of jewelry testing equipment, specifically a jewelry testing fixing device with anti-slip function. Background Technology

[0002] Jewelry testing fixtures are common auxiliary tools used to stably hold jewelry during testing, ensuring the accuracy of results and the safety of the operation. Jewelry testing typically requires observation and analysis of the jewelry from multiple angles and in detail; therefore, the fixture must securely hold the jewelry while preventing damage.

[0003] Because jewelry surfaces are typically smooth and made of various materials, slippage can easily occur during the fixing process due to insufficient clamping force or low friction between the contact surfaces. This slippage not only affects detection efficiency but may also cause jewelry to accidentally fall off, increasing the risk of damage or loss. Furthermore, existing fixing devices are often not adequately designed with anti-slip features in mind, leading to limitations in their practical use.

[0004] In view of the above-mentioned technologies, the inventors believe that there is room for improvement in the anti-slip performance of existing jewelry testing fixtures. Therefore, they have proposed a jewelry testing fixture with anti-slip function to solve the above problems. Utility Model Content

[0005] To address the problem of jewelry slippage caused by insufficient clamping force or low friction on the contact surface during use of jewelry testing and fixing devices, this utility model provides a jewelry testing and fixing device with anti-slip function.

[0006] The present invention provides a jewelry testing and fixing device with anti-slip function, which adopts the following technical solution:

[0007] A jewelry testing and fixing device with anti-slip function includes a base. A support column is fixedly mounted in the middle of the upper end face of the base. A rotating disk is threadedly connected to the top of the support column. An annular groove is formed on the upper end face of the rotating disk, and a plurality of balls are embedded in the annular groove, forming a rolling engagement between the balls and the inner wall of the annular groove. A fixing clamp is fixedly mounted at the center of the upper end face of the rotating disk. An arc-shaped groove is formed on one side of the fixing clamp. An elastic anti-slip pad is adhered to the inner wall of the arc-shaped groove. A plurality of raised particles are evenly distributed on the surface of the elastic anti-slip pad. The rotating disk has a movable clamping seat slidably mounted on the side of its upper surface near the fixed clamping seat. The bottom of the movable clamping seat is slidably connected to the upper surface of the rotating disk via a linear guide rail. One side of the movable clamping seat also has an arc-shaped groove, and an elastic anti-slip pad is adhered to the inner wall of the arc-shaped groove. The surface of the elastic anti-slip pad is evenly distributed with several raised particles. An adjusting screw is installed on the other side of the movable clamping seat via a threaded connection. One end of the adjusting screw passes through the movable clamping seat and is rotatably connected to one side of the fixed clamping seat. A handwheel is fixedly installed on the other end of the adjusting screw.

[0008] Preferably, the elastic anti-slip pad is made of silicone material, the raised particles are hemispherical, the height of the raised particles is 0.5mm to 1mm, and the distance between two adjacent raised particles is 2mm to 3mm.

[0009] Preferably, the number of balls is six, and the balls are evenly distributed inside the annular groove. The diameter of the balls is slightly smaller than the depth of the annular groove, so that the balls can roll freely inside the annular groove without leaving the annular groove.

[0010] Preferably, the inner walls of the arc-shaped grooves of both the fixed clamping seat and the movable clamping seat are sanded to increase surface roughness and further enhance friction.

[0011] Preferably, the outer surface of the adjusting screw is provided with a bidirectional thread, and both ends of the adjusting screw are respectively connected to the movable clamping seat and the fixed clamping seat through threads. The adjusting screw is rotated by rotating the handwheel, thereby realizing the movement of the movable clamping seat along the linear guide rail.

[0012] Preferably, there are two linear guide rails, which are symmetrically arranged on both sides of the upper surface of the rotary disk. The bottom of the movable clamping seat is slidably connected to the linear guide rails via a slider. A lubricating coating is provided between the slider and the linear guide rails to reduce frictional resistance.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] By bonding elastic anti-slip pads to the inner walls of the arc-shaped grooves of the fixed and movable clamping seats, and evenly distributing raised particles on the surface of the elastic anti-slip pads, the friction of the clamping contact surfaces can be effectively increased, preventing jewelry from slipping during inspection. Simultaneously, the elastic anti-slip pads are made of silicone material, possessing a certain degree of flexibility, which can cushion and protect the jewelry during clamping, preventing damage to its surface. By creating an annular groove on the upper surface of the rotating disk and embedding ball bearings, the rotating disk can rotate freely on the base, facilitating multi-angle observation and inspection of the jewelry. By adjusting the screw's threaded connection with the movable and fixed clamping seats, combined with the sliding engagement of the linear guide rail, the movement distance of the movable clamping seat can be precisely controlled, thereby achieving stable clamping of jewelry of different sizes. Furthermore, the inner walls of the arc-shaped grooves are frosted, further enhancing the friction of the clamping contact surfaces and strengthening the overall anti-slip performance. Compared to existing technologies, this invention solves the problem of reduced inspection efficiency due to jewelry slippage during inspection, while also reducing the risk of accidental jewelry falling off, significantly improving the practicality and reliability of the jewelry inspection and fixing device.

[0023] This utility model provides a jewelry detection and fixing device with anti-slip function. Its specific structure and implementation are described in detail below with reference to the accompanying drawings. First, refer to... Figure 1 The overall structural diagram shows that the base 1 serves as the foundation of the entire device. A support column 2 is fixed to the center of the upper surface of the base 1 by welding or bolts. The top of the support column 2 has external threads, which connect to the internal threaded hole at the bottom of the rotating disk 3, allowing for the detachable installation of the rotating disk 3 on the base 1. An annular groove 4 is formed on the upper surface of the rotating disk 3, and six ball bearings 5 ​​are embedded inside the annular groove 4. (Refer to...) Figure 2 The cross-sectional view shows that the ball bearing 5 and the inner wall of the annular groove 4 form a rolling fit. The diameter of the ball bearing 5 is slightly smaller than the depth of the annular groove 4, allowing the ball bearing 5 to roll freely within the annular groove 4 without detaching from it. A fixing clamp 6 is fixedly mounted to the center of the upper end face of the rotating disk 3 by screws. An arc-shaped groove 8 is provided on one side of the fixing clamp 6, and an elastic anti-slip pad 9 is adhered to the inner wall of the arc-shaped groove 8. (See reference...) Figure 4 It can be observed that the surface of the elastic anti-slip mat 9 is evenly distributed with several raised particles 10. The raised particles 10 are hemispherical, with a height of 0.5mm to 1mm, and the distance between two adjacent raised particles 10 is 2mm to 3mm.

[0024] The movable clamping seat 7 is slidably connected to the linear guide rail 13 via a slider 14 at its bottom. There are two linear guide rails 13, symmetrically arranged on both sides of the upper surface of the rotating disk 3. A lubricating coating is applied between the slider 14 and the linear guide rail 13 to reduce frictional resistance. One side of the movable clamping seat 7 also has an arc-shaped groove 8. An elastic anti-slip pad 9 is adhered to the inner wall of the arc-shaped groove 8. The surface of the elastic anti-slip pad 9 has several evenly distributed raised particles 10, the shape, height, and spacing of which are consistent with the elastic anti-slip pad 9 on the fixed clamping seat 6. The other side of the movable clamping seat 7 is connected to an adjusting screw 11 via a threaded connection. One end of the adjusting screw 11 passes through the movable clamping seat 7 and is rotatably connected to a bearing hole on one side of the fixed clamping seat 6. The other end of the adjusting screw 11 is fixedly connected to a handwheel 12 via a keyway. (Reference) Figure 5 It can be seen that the outer surface of the adjusting screw 11 is provided with a bidirectional thread. The two ends of the adjusting screw 11 are respectively connected to the movable clamping seat 7 and the fixed clamping seat 6 by thread. By rotating the handwheel 12, the adjusting screw 11 is driven to rotate, thereby realizing the movement of the movable clamping seat 7 along the linear guide rail 13.

[0025] The inner walls of the arc-shaped grooves 8 of both the fixed clamping seat 6 and the movable clamping seat 7 are frosted to increase surface roughness. The elastic anti-slip pad 9 is made of silicone material, which has a certain degree of flexibility and can cushion and protect the jewelry during clamping. In actual operation, the jewelry to be tested is placed between the arc-shaped grooves 8 of the fixed clamping seat 6 and the movable clamping seat 7. By rotating the handwheel 12, the adjusting screw 11 is rotated. Since the adjusting screw 11 adopts a bidirectional thread design, the movable clamping seat 7 will move along the linear guide rail 13 towards the fixed clamping seat 6 until the elastic anti-slip pad 9 is tightly attached to the surface of the jewelry. At this time, the raised particles 10 on the surface of the elastic anti-slip pad 9 increase the friction of the contact surface, while the flexibility of the silicone material can avoid damaging the surface of the jewelry. If it is necessary to observe the jewelry from multiple angles, the rotating disk 3 can be manually rotated. The ball bearings 5 ​​at the bottom of the rotating disk 3 roll in the annular groove 4, allowing the rotating disk 3 to rotate freely and maintain a stable state.

[0026] In the above embodiments, the positional relationships of the various components are clearly defined. For example, the base 1, as the basic component, is located at the bottom. The support column 2 is vertically fixed to the center of the upper surface of the base 1. The rotating disk 3 is installed on the top of the support column 2 via a threaded connection. The fixed clamping seat 6 and the movable clamping seat 7 are located at the center and near the center of the upper surface of the rotating disk 3, respectively. The connection relationships between the components are also clearly visible. For example, the fixed clamping seat 6 is fixed to the center of the upper surface of the rotating disk 3 by screws. The movable clamping seat 7 is slidably connected to the linear guide rail 13 via a slider 14. The adjusting screw 11 is connected to both the movable clamping seat 7 and the fixed clamping seat 6 via threaded connections. The mutual cooperation between the components is reflected in the fact that the rotation of the adjusting screw 11 drives the movable clamping seat 7 to move along the linear guide rail 13, thereby achieving stable clamping of jewelry of different sizes. The rotating disk 3 achieves free rotation through the rolling cooperation of the ball bearing 5 and the annular groove 4, facilitating multi-angle observation of the jewelry.

[0027] In practical applications, this device is suitable for jewelry testing laboratories or jewelry processing workshops. The operator first places the jewelry in the arc-shaped groove 8 of the fixed clamping seat 6, then rotates the handwheel 12. This, through the bidirectional threading of the adjusting screw 11, moves the movable clamping seat 7 towards the fixed clamping seat 6 until the elastic anti-slip pad 9 tightly adheres to the jewelry surface. During this process, the raised particles 10 on the surface of the elastic anti-slip pad 9 significantly increase the friction of the clamping contact surface. Simultaneously, the flexibility of the silicone material provides cushioning protection for the jewelry, preventing damage to the jewelry surface due to excessive clamping force. If it is necessary to observe the jewelry from different angles, the operator simply rotates the rotating disk 3 by hand. The ball bearings 5 ​​at the bottom of the rotating disk 3 roll within the annular groove 4, allowing the jewelry to rotate freely on a horizontal plane, facilitating comprehensive observation and data recording by the testing personnel. The entire device is rationally designed, with tight assembly between components and easy operation, ensuring stability and safety during jewelry testing.

[0028] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0029] In actual operation at the jewelry testing laboratory, the jewelry to be tested is first placed in the arc-shaped groove 8 of the fixed clamping seat 6. The arc-shaped groove 8 is designed to accommodate jewelry of different shapes, ensuring the stability of its initial positioning. Then, the operator rotates the handwheel 12, which drives the adjusting screw 11 to rotate via a keyway connection. Because the outer surface of the adjusting screw 11 has a bidirectional thread, and both ends of the adjusting screw 11 are threadedly connected to the movable clamping seat 7 and the fixed clamping seat 6 respectively, the rotation of the adjusting screw 11 drives the movable clamping seat 7 to move along the linear guide rail 13 towards the fixed clamping seat 6. During this process, the sliding block 14 at the bottom of the movable clamping seat 7 and the linear guide rail 13 have reduced frictional resistance due to the presence of a lubricating coating, ensuring smooth and stable movement of the movable clamping seat 7.

[0030] As the movable clamping seat 7 gradually approaches the fixed clamping seat 6, the elastic anti-slip pads 9, bonded to the inner walls of the arc-shaped grooves 8 of both, begin to contact the jewelry surface. Made of silicone, the elastic anti-slip pads 9 possess a degree of flexibility, providing cushioning and protection for the jewelry during clamping. Furthermore, the evenly distributed raised particles 10 on the surface of the elastic anti-slip pads 9 significantly increase the friction of the contact surface. These raised particles 10 are hemispherical, with a height of 0.5mm to 1mm, and a spacing of 2mm to 3mm between adjacent particles. This design effectively enhances the anti-slip performance during clamping. Simultaneously, the inner walls of the arc-shaped grooves 8 of both the fixed clamping seat 6 and the movable clamping seat 7 are frosted, further increasing surface roughness and thus enhancing overall friction. This multi-layered anti-slip design ensures that the jewelry will not slip due to smooth surfaces or diverse materials during clamping.

[0031] If multi-angle observation of the jewelry is required, the operator can achieve this by manually rotating the rotating disk 3. Six ball bearings 5 ​​embedded at the bottom of the rotating disk 3 roll within an annular groove 4, forming a rolling engagement between the ball bearings 5 ​​and the inner wall of the groove 4, allowing the rotating disk 3 to rotate freely and remain stable. The diameter of the ball bearings 5 ​​is slightly smaller than the depth of the annular groove 4, ensuring that the ball bearings 5 ​​do not detach from the groove 4 while rolling freely within it. This structural design not only improves the flexibility of rotation but also ensures stability during rotation, facilitating observation and data recording of the jewelry from different angles by the inspector.

[0032] During the above operation, the support column 2 is installed in the middle of the upper end face of the base 1 via a threaded connection, providing a stable foundation for the entire device. The rotating disk 3 is installed on top of the support column 2 via a threaded connection, ensuring its detachability for easy maintenance and replacement. The fixed clamping seat 6 is fixed to the center of the upper end face of the rotating disk 3 with screws, while the movable clamping seat 7 is slidably connected to the linear guide rail 13 via a slider 14. This assembly method ensures a tight connection between the components and facilitates operation. The bidirectional threaded design of the adjusting screw 11, combined with the sliding engagement of the linear guide rail 13, enables precise clamping of jewelry of different sizes, while the rotating disk 3 achieves free rotation through the rolling engagement of the ball bearing 5 and the annular groove 4.

[0033] Through the above steps, the device achieves stable clamping and multi-angle observation of jewelry, solving the problem of jewelry slippage caused by insufficient clamping force or low friction on the contact surface in existing technologies. The raised particles 10 of the elastic anti-slip pad 9 and the frosted treatment of the inner wall of the arc-shaped groove 8 work together to significantly improve the friction of the clamping contact surface, preventing the jewelry from slipping during the inspection process. At the same time, the flexibility of the silicone material can cushion and protect the jewelry, preventing damage to the jewelry surface due to excessive clamping force. The free rotation function of the rotating disk 3 further enhances the practicality of the device, meeting the need for multi-angle observation during jewelry inspection.

[0034] In summary, through its specific structural design and operating principle, this utility model can effectively solve the technical problems existing in jewelry testing fixtures in practical applications, ensuring the stability and safety of the jewelry testing process.
