Description

Technical Field

[0001] This utility model relates to the field of jewelry design technology, and more specifically, to a workbench for jewelry design. Background Technology

[0002] As the jewelry and fashion accessories industry develops towards personalization and refinement, traditional fixed workbenches can no longer meet the design requirements of complex accessories (such as three-dimensional jewelry, adjustable chains, etc.). Traditional workbenches have the following limitations: (1) Fixed viewing angle limitation: Accessories need to be observed from multiple angles to ensure the symmetry and proportional coordination of the design, but traditional workbenches cannot be rotated, and the position needs to be adjusted manually, which is inefficient and easy to cause fatigue; (2) Lack of tension adjustment function: During the assembly process, accessories need to be stretched or fixed manually, which can easily lead to deformation or loosening of the connection due to uneven force; (3) Simple support structure: Traditional clamps or brackets are too rigid, which can easily damage soft materials (such as leather and silicone), and cannot adapt to the fixing requirements of irregular parts; (4) Space occupation and operation complexity: The assembly of multiple parts requires frequent tool changes or adjustment of workpiece position, and the traditional workbench layout is scattered, which affects the continuity of work.

[0003] In existing technologies, only a single-angle support can be provided during the use of jewelry design, and the viewing direction of the jewelry cannot be dynamically adjusted. Repeated disassembly and reassembly are required, and manual stretching or simple clamps are relied upon, making it difficult to accurately control the tightness of flexible components such as chains and ropes. Therefore, we have made improvements to this and proposed an operating table for jewelry design. Utility Model Content

A straight groove 12 is provided at the lower end of the slide groove 13. A linkage groove is provided on one side of the straight groove 12. A slider 14 is provided at the inner end of the linkage groove.

[0031] The hemispherical platform 5 rotates along the hemispherical groove. Lubricant is applied between the hemispherical platform 5 and the hemispherical groove. The positioning frame 6 is fixed on the upper side of the inner end of the design groove. Both ends of the positioning frame 6 are made of silicone. The lower end of the moving frame 7 is fixedly connected to the linkage frame 18. The lower end of the linkage frame 18 is fixedly connected to one end of the toothed rod 15.

[0032] The toothed rod 15 has toothed grooves arranged at equal intervals inside. The toothed rod 15 meshes with the gear 16. The gear 16 is perpendicular to the central axis of the surface of the hemispherical table 5. The gear 16 is fixedly connected to the linkage rod 17. The top end of the linkage rod 17 is fixedly connected to the throttle 8.

[0033] The outer end of the linkage rod 17 is provided with a linkage cylinder, which runs through the upper and lower ends of the hemispherical table 5. The linkage cylinder is connected to the sliding cylinder 9. The positioning plate 20 is fixed to the linkage rod 17 and slides up and down along the sliding cylinder 9.

[0034] The upper end of the linkage spring 19 is movably connected to the upper inner surface of the slide cylinder 9, the lower end of the linkage spring 19 is fixedly connected to the upper outer surface of the positioning plate 20, the lower end of the linkage rod 17 is fixedly connected to the positioning block 11, the positioning block 11 is an equilateral polygon, and the positioning block 11 and the positioning groove 10 are interlocked.

[0035] The linkage frame 18 slides along the slide groove 13, and the length of the slide groove 13 is less than half the length of the straight groove 12. The straight groove 12 and the linkage groove are interconnected. The slider 14 slides back and forth along the linkage groove. The slider 14 is fixedly connected to the rear end of the toothed rod 15. The slider 14 is located at the end of the toothed rod 15 away from the movable frame 7.

[0036] One embodiment is used for necklace assembly and tension adjustment: The designer places the necklace components to be assembled into the design slot, selects the required accessories (such as chains, pendants, etc.) from the parts box 4 at the front of the armrest 3 for assembly; after assembly, the main body of the necklace is placed on the silicone end of the positioning frame 6, with the drooping part passing under the moving frame 7; the handle 8 is pulled upwards, driving the linkage rod 17 to compress the linkage spring 19, causing the positioning block 11 to disengage from the positioning slot 10, releasing the locking state of the hemispherical platform 5; the handle 8 is rotated clockwise, driving the toothed rod 15 to move to the right along the straight slot 12 through the gear 16, and the linkage frame 18 drives the moving frame 7 to slide to the right along the slide groove 13; the moving frame 7 gradually tightens the drooping section of the necklace, and the silicone positioning frame 6 bends slightly under the tension to buffer the tension; when the tension is appropriate, the handle 8 is released, and the linkage spring 19 rebounds to push the positioning block 11 into the positioning slot 10 at the current position, fixing the angle of the hemispherical platform 5; check whether the position of each part of the necklace meets the design requirements, and repeat the previous steps for fine-tuning if necessary.

[0037] Another embodiment is used for multi-angle styling review of the design after completion: After initial tension adjustment, the designer finds that the pendant angle needs adjustment; pinch the handle 8 again and lift it upwards to disengage the positioning block 11 from the positioning groove 10. At this time, the handle 8 can be held with both hands; slowly rotate the hemispherical platform 5 horizontally to a 45° tilt angle to observe the light refraction effect on the side of the pendant; after finding the best display angle, slowly release the handle 8, and the positioning block 11 automatically engages with the corresponding positioning groove 10 under the action of the linkage spring 19; keep the hemispherical platform 5 tilted, and readjust the position of the moving frame 7 to fine-tune the curvature of the necklace hem; through the 90° annular positioning groove 10 system of the hemispherical platform 5, the all-round observation angles such as front view, side view, and top view can be quickly switched; after confirming the multi-angle view, the jewelry is disassembled for the next process.

[0038] In use, the following steps are taken: First, the ornament is designed and then assembled within the design slot. The tools used for assembly are retrieved from the parts box 4 at the front end of the armrest 3. After the ornament is assembled, it is necessary to support it and check whether each part conforms to the design. Figure 1 To place the jewelry, such as a necklace, on the positioning frame 6, with the lower end of the necklace positioned at the lower end of the moving frame 7, pull the handle 8 upwards. After the handle 8 moves upwards, the positioning block 11 located at the lower end of the linkage rod 17 leaves the positioning groove 10. At this point, the connection between the hemispherical platform 5 and the hemispherical groove is released, and the hemispherical platform 5 can rotate. Simultaneously, the rotation of the handle 8 drives the rotation of the gear 16. The positioning rotation of the gear 16 can push the toothed rod 15 to move along the straight groove 12. The movement of the toothed rod 15 is connected by the slider 14 and the linkage groove, enabling the stable movement of the toothed rod 15. During the movement of the toothed rod 15, the moving frame 7 connected to the linkage frame 18 on the toothed rod 15 moves along the sliding groove 12. 3. For jewelry with a gradually tightening design, such as a necklace, after tightening, the silicone material at both ends of the positioning frame 6 bends slightly downward to avoid the jewelry connection being too tense. At this time, lower the handle 8, and the linkage spring 19 drives the positioning plate 20 to slide downward along the slide cylinder 9. At the same time, the positioning block 11 at the lower end of the linkage rod 17 is engaged in the positioning groove 10. If it is necessary to change the angle of the hemispherical table 5, the hemispherical table 5 can be rotated along the hemispherical groove before the handle 8 is fully lowered. The area of ​​the hemispherical groove is greater than half the area of ​​the entire sphere. This ensures that the opening end of the hemispherical groove retracts inward and does not affect the rotation of the hemispherical table 5 inside it. Lower the handle 8 when you feel it is in a suitable position.

[0039] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.
