Detailed implementation manners

[0028] In order to make the technical problems, technical solutions and beneficial effects solved by this application clearer, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0029] Please refer to Figures 1 to 5 , a positioning structure for a watch case, including a watch case body 1 and a watch case outer ring 2 detachably connected to the watch case body 1. An installation position 4 for placing an ornament 3 is provided on the watch case body 1 along its circumferential direction. A positioning claw 5 for positioning the ornament 3 is provided at the outer edge of the outer circle of the installation position 4. The watch case body 1 is connected to the watch case outer ring 2 to fix the ornament 3 in the installation position 4.

[0030] In a positioning structure for a watch case of this application, through the setting of the positioning claw, after the ornament is placed in the installation position, the positioning claw can be first pressed to position the ornament. Since the force required to press the positioning claw is small and the pressing force is easier to control, this split design reduces the risk of damaging the ornament. Finally, the watch case outer ring is sleeved on the watch case body and connected to fix the ornament in the installation position, which not only ensures the strength of the watch case but also solves the problem in the prior art that the ornament is easily broken when being pressed and fixed due to the relatively thick watch case, improves the production efficiency and reduces the production cost.

[0031] Further, as a preferred implementation manner of this solution rather than a limitation, when the positioning claw 5 is in the unfolded state, the top of the positioning claw 5 unfolds upward for the ornament 3 to be placed in the installation position 4. When the positioning claw 5 is in the positioning state, the top of the positioning claw 5 bends inward to position the ornament 3.

[0032] In this embodiment, when the positioning claw is in the unfolded state, the design that its top unfolds upward enables the ornament to be conveniently placed in the installation position, improving the assembly efficiency. In the positioning state, the top of the positioning claw bends inward, which can effectively fix the ornament in the installation position and prevent it from loosening or falling off. This design not only simplifies the assembly process but also enhances the fixing effect of the ornament, improving the reliability and aesthetics of the product.

[0033] Further, as a preferred implementation manner of this solution rather than a limitation, the watch case outer ring 2 includes a connecting portion 21 located outside the positioning claw 5 and a limiting portion 22 located above the positioning claw 5.

[0034] In this embodiment, the fixing effect of the ornament is enhanced. The connection between the connecting part and the watch case body ensures the stability of the ornament, while the limiting part limits the top of the positioning claw to prevent it from moving, thus providing double fixing guarantees. The design of the outer ring of the watch case can be directly sleeved on the watch case body from top to bottom for the next step of welding. This design improves the assembly efficiency. The positioning functions of the connecting part and the limiting part make the assembly process faster and more accurate, reducing the time for adjustment and calibration. In addition, the limiting part also plays a role in protecting the positioning claw, preventing it from being damaged during assembly or use.

[0035] Further, as a preferred implementation manner rather than a limitation of this solution, a chamfer transition 23 is provided between the connecting part 21 and the limiting part 22.

[0036] In this embodiment, the possibility of the connecting part and the limiting part breaking or deforming during assembly or use is reduced. The aesthetic property of the outer ring of the watch case is enhanced, making the overall appearance more natural and smooth. At the same time, the risk of wear or damage caused by external forces is also reduced.

[0037] Further, as a preferred implementation manner rather than a limitation of this solution, the installation position 4 includes a counterbore 41 and a first card slot 42 that fits with one side of the ornament 3.

[0038] In this embodiment, the design improves the assembly efficiency. The positioning functions of the counterbore and the first card slot enable the ornament to be quickly and accurately inserted into the installation position, reducing the adjustment and calibration time during the assembly process. In addition, the counterbore and the first card slot also play a role in protecting the ornament, preventing the ornament from being damaged during assembly or use.

[0039] Further, as a preferred implementation manner rather than a limitation of this solution, the positioning claw 5 is bent inward to form a second card slot 51 that fits with the other side of the ornament 3.

[0040] In this embodiment, the second card slot and the first card slot cooperate with each other to clamp both sides of the ornament 3, jointly fixing the ornament firmly in the installation position, thereby improving the stability and reliability of the ornament and reducing the risk of loosening or falling off.

[0041] Further, as a preferred implementation manner rather than a limitation of this solution, it includes a plurality of the ornaments 3 and a plurality of the positioning claws 5, and each of the ornaments 3 is correspondingly arranged with two of the positioning claws 5.

[0042] In this embodiment, the fixing effect of the ornament is enhanced. Each ornament is fixed by two positioning claws. Compared with a single positioning claw, this design provides greater clamping force and better stability, effectively preventing the ornament from loosening or falling off, thereby improving the reliability and durability of the product.

[0043] Further, as a preferred implementation manner of this solution rather than a limitation, the watch case body 1 and the watch case outer ring 2 are laser welded.

[0044] In this embodiment, laser welding can achieve high-strength connection, firmly combine the watch case body and the watch case outer ring together, and improve the stability and reliability of the overall structure. This connection method can withstand large external forces and vibrations, and is not prone to looseness or fracture. Laser welding has high-precision positioning ability. It can accurately control the welding position and depth, ensure the connection quality between the watch case body and the watch case outer ring, reduce assembly errors, and improve the precision and consistency of the product. It can quickly complete the connection between the watch case body and the watch case outer ring, improve production efficiency, and reduce production costs. Compared with traditional welding methods, laser welding does not require a large amount of welding materials and auxiliary equipment, reducing energy consumption and environmental pollution.

[0045] Further, as a preferred implementation manner of this solution rather than a limitation, a positioning hole 11 is also provided at the bottom of the watch case body 1.

[0046] In this embodiment, the setting of the positioning hole improves the assembly precision. During the assembly process, the positioning hole can be used as a reference point to ensure the accurate alignment of the watch case body and the watch case outer ring, thereby improving the assembly precision and efficiency.

[0047] Further, as a preferred implementation manner of this solution rather than a limitation, the height of the first connection surface 52 between two adjacent positioning claws 5 corresponding to the same ornament 3 is lower than the height of the second connection surface 53 between two adjacent positioning claws 5 corresponding to the adjacent ornament 3.

[0048] In this embodiment, the fixing effect of the ornament is enhanced. Since the height of the first connection surface is lower, the two positioning claws corresponding to the same ornament can clamp the ornament more tightly, providing a greater clamping force, thereby effectively preventing the ornament from loosening or falling off and improving the reliability of the product.

[0049] The working principle of this embodiment is as follows:

[0050] A positioning structure for a watch case according to the present application, through the setting of positioning claws, after the ornament is placed in the installation position, the positioning claws can be first pressed to position the ornament. Since the force required to press the positioning claws is small and the pressing force is easier to control, this split design reduces the risk of damaging the ornament. Finally, the watch case outer ring is sleeved on the watch case body for connection to fix the ornament in the installation position, which not only ensures the strength of the watch case but also solves the problem in the prior art that the ornament is easily broken when being pressed and fixed due to the relatively thick watch case, improves production efficiency, and reduces production costs.

[0051] The above are the implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of this application is only limited to these descriptions. Any implementation that is approximately the same as the method structure of this application, or any technical deduction or replacement made on the premise of the concept of this application, shall be regarded as the protection scope of this application.
