Description

Technical Field

[0001] This utility model relates to the field of watch technology. Background Technology

[0002] Currently, adhesive bonding is widely used in the fixing process of decorative components on watch dials. Its core principle is to bond the decorative ring to the main dial substrate using organic adhesives (such as epoxy resin, cyanoacrylate, etc.). However, this technology has the following significant drawbacks in practical applications:

[0003] Reliability issues caused by adhesive aging: Adhesives are susceptible to performance degradation due to environmental factors during long-term use, which eventually leads to a decrease in bonding strength. Decorative plates are prone to displacement, warping, or even falling off, directly affecting the product's aesthetics and functionality.

[0004] High maintenance costs: Once the adhesive fails, the watch crystal needs to be disassembled, the residual adhesive removed, and then re-attached. The repair process is complicated and there is a risk of damaging the dial coating. Frequent repairs will further shorten the lifespan of the watch.

[0005] Therefore, there is room for improvement in the existing techniques for installing decorative plates on watch dials. Utility Model Content

[0028] See appendix Figure 1-6 The image shows a watch dial with a decorative ring detachment feature. The watch dial 1 includes a ring-shaped main ring 2, an inner ring 6, an outer ring 4, and a decorative ring 3. The inner side of the top of the main ring 2 extends upward to form an annular boss 20, and the outer side of the top of the main ring 2 forms a platform surface 21. The inner ring 6 fits around the annular boss 20, and the outer ring 4 fits around the inner ring 6. Both the inner ring 6 and the outer ring 4 rest on the platform surface 21 and are locked together by fasteners. The upper part of the outer ring 4 extends upward beyond the inner ring 6, and the upper part of the outer ring 4 extends inward to form a stop flange 41. An embedding groove 8 is formed between the stop flange 41 and the top surface of the inner ring 6, and the decorative ring 3 is nested and fixed within the embedding groove 8.

[0029] The main bezel 2 is generally made of stainless steel and is formed into a common ring frame structure such as square or round. The bottom of the main bezel 2 is sealed by the back case 7 and the top is sealed by the watch crystal 5, forming an installation space in the middle to install the various parts of the dial 1. Lugs are provided on the outer periphery of the main bezel 2 to connect the watch strap.

[0030] The top inner side of the main ring body 2 extends upward to form an annular boss 20. The annular boss 20 is higher than the outer side of the top of the main ring body 2, forming a platform surface 21. The inner ring 6 fits the shape of the annular boss 20, fitting around its periphery, and the bottom surface of the inner ring 6 abuts against the platform surface 21. The outer ring 4 and the inner ring 6 are usually steel rings, fitting together. The outer ring 4 fits around the inner ring 6, and the bottom surface of the outer ring 4 abuts against the platform surface 21. The outer ring 4 and the inner ring 6 are locked together by fasteners, preferably screws.

[0031] The upper part of the outer ring 4 is higher than the inner ring 6, and the stop flange 41 is suspended above the inner ring 6. This forms an annular insertion groove 8 below the stop flange 41 and above the inner ring 6. The decorative ring 3 is inserted into this groove 8, and the outer ring 4 and inner ring 6 work together to clamp and lock the decorative ring 3. Compared to adhesive bonding, the fixing method of the decorative ring 3 in this embodiment is unlikely to experience performance degradation due to environmental factors, ensuring stable and reliable installation of the decorative ring 3. Furthermore, the structure is easy to disassemble and maintain, which helps extend the product's service life.

[0032] In some embodiments, the outer periphery of the inner ring 6 extends horizontally to form a skirt 60, the inner wall of the outer ring 4 forms a positioning groove 40, and the skirt 60 is embedded in the positioning groove 40.

[0033] Specifically, the bottom of the inner ring 6 extends horizontally outward to form a skirt 60. Correspondingly, the bottom of the inner wall of the outer ring 4 is recessed to form an annular positioning groove 40, and the skirt 60 enters the positioning groove 40, thereby enhancing the stability of the fit between the outer ring 4 and the inner ring 6, and also facilitating the quick fitting of the outer ring 4 and the inner ring 6 into place. To enhance the stability of the structure, anti-slip textures can be provided on the bottom of the inner end to increase the friction between it and the platform surface 21.

[0034] In some embodiments, the outer side of the decorative ring 3 is fixed to the embedding groove 8, and the inner side of the decorative ring 3 extends out of the embedding groove 8 and is pressed against the annular boss 20. Preferably, an annular groove is formed along the inner bottom wall of the decorative ring 3, and the top of the annular boss 20 is embedded in the annular groove.

[0035] The outer side of the decorative ring 3 is held and fixed in the embedding groove 8 by the outer ring 4 and the inner ring 6. Its inner side is supported upward by the annular boss 20, and the inner side of the decorative ring 3 forms an annular groove. The top of the annular boss 20 is embedded in the annular groove, which strengthens the positioning and fit between the structures and ensures the stability of the structural connection.

[0036] In some embodiments, the inner circumference of the annular boss 20 is provided with a supporting step 201, and a watch mirror 5 is installed on the supporting step 201; the peripheral sidewall of the watch mirror 5 abuts against and fits against the inner sidewall of the decorative ring 3.

[0037] The inner wall of the annular boss 20 has a supporting step 201 with a horizontal bearing surface. The watch mirror 5 rests on the bearing surface, and the outer contour of the watch mirror 5 fits into the inner circumference of the decorative ring 3, so that its surrounding sidewalls are tightly abutted against the inner sidewalls of the decorative ring 3, thus fixing it in place. Furthermore, the connection between the watch mirror 5 and the bearing surface of the supporting step 201 can be strengthened by adhesive bonding.

[0038] A watch is provided, the watch including a strap connected to a dial 1 as described in any of the preceding claims.

[0039] In summary, the improved dial 1 has an inner ring 6 and an outer ring 4 mounted on its main ring. The inner ring 6 and outer ring 4 are reinforced by fasteners such as screws 9, forming an insert groove 8 between them. The decorative ring 3 is embedded in this insert groove 8 for stable installation. Compared to the previous adhesive installation method, the improved decorative ring 3 is more secure and reliable, easier to maintain, and its installation stability is less affected by the environment, which helps extend the service life of the dial 1.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
