Description

Technical Field

[0001] This utility model relates to the field of ring watch structure technology, specifically to an assembly structure for a ring watch. Background Technology

[0002] Timekeeping devices are used to record time, and clocks or watches are generally used to record and display the accurate time of the day. Among them, watches are mostly wristwatches worn on the wrist, but with the development of the times, ring watches worn on the fingers have also appeared.

[0003] Current ring watches need to meet two technical challenges: thinness and water resistance. Traditional manufacturing generally uses two assembly methods: First, the case back, middle frame, and glass are often connected by simple flat pressing or simple snap-fit ​​structures. However, these structures have poor stability and impact resistance. When subjected to external impacts or pressure, the components are prone to slight relative displacement or deformation, leading to seal failure, or even causing the glass to crack or the movement to be damaged, affecting the seal and the overall thickness of the watch. Second, the positioning of components often relies on multiple precise alignment points or screws for fixing. The assembly process is cumbersome, requiring a high level of worker skill and precision in parts processing, which increases production costs and defect rates.

[0004] At the same time, the two assembly methods mentioned above will affect the aesthetics and structure of the ring watch. In order to pursue a thin and beautiful appearance, the middle frame and the back case may be made thinner, which will further sacrifice structural strength and sealing space, making it difficult to achieve both. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] Please see Figures 1 to 4 The present invention provides an embodiment of an assembly structure for a ring watch, which mainly consists of a bottom shell 1, a middle frame 2, and a glass 3.

[0026] During assembly, first, place the sealing ring 11 into the annular recess 10 at the bottom of the middle frame 2. Then, align the annular protrusion 4 of the bottom shell 1 with the opening 5 at the bottom of the middle frame 2 and apply upward pressure to make the annular protrusion 4 embed into the opening 5. During this process, the edge 6 at the top of the annular protrusion 4 will contact and slide with the inclined surface 7 of the inner wall of the middle frame 2. The guiding effect of the inclined surface 7 causes the bottom of the middle frame 2 to expand slightly elastically. At the same time, the annular protrusion 4 elastically contracts inward until the edge 6 passes the lowest point of the inclined surface 7. The middle frame 2 rebounds, so that the lower surface of the edge 6 completely contacts the inclined surface 7. At the same time, the top of the bottom shell 1 and the bottom edge of the middle frame 2 also come into close contact, completing the locking of the bottom shell 1 and the middle frame 2. The elliptical sealing ring 11 is fully compressed during this process, forming the first seal.

[0027] Furthermore, the embedded design of the annular protrusion 4 and the opening 5 constitutes a robust radial positioning, effectively preventing horizontal misalignment between the bottom shell 1 and the middle frame 2; the cooperation between the rim 6 and the inclined surface 7 forms axial locking and radial support. When the bottom shell 1 is assembled upwards, the rim 6 and the inclined surface 7, which slopes inwards from top to bottom, come into close contact, generating an inward clamping force, which makes the bottom of the middle frame tightly "hold" the annular protrusion 4 of the bottom shell, greatly enhancing the rigidity and deformation resistance of the joint.

[0028] The elliptical cross-section sealing ring 11, which is set in the annular recess 10, can provide a larger contact area and resilience than the circular cross-section when compressed, forming the first reliable static waterproof barrier.

[0029] Subsequently, the movement 13 is installed into the mounting cavity 12 formed by the bottom case 1 and the middle frame 2.

[0030] Finally, align the glass 3 with the opening 8 at the top of the middle frame 2 and press it in from top to bottom. The periphery of the glass 3 is press-fitted with the inner wall of the middle frame 2, and the force is evenly distributed during the pressing process. When the glass 3 falls to a certain extent, its bottom surface will contact the right-angled top surface of the limiting platform 9 on the inner wall of the middle frame 2, thus being precisely limited in the axial position and unable to continue to descend, and the assembly is complete.

[0031] Furthermore, the interference fit between the glass 3 and the middle frame 2, and the limiting platform 9, allow the glass 3 to be embedded from top to bottom. The interference fit on the periphery provides uniform clamping force, and the bottom is supported by the right-angled top surface of the limiting platform 9, ensuring that the glass is firmly fixed in any direction and has extremely strong resistance to pressure and impact.

[0032] For the adjustment assembly, first press the sleeve 16 into the through hole 14 of the middle frame 2 and fix it. Then, the sealing ring 19, the gasket 20, and the elastic element 21 are sequentially placed into the receiving space 18 inside the knob 17. Then, the adjustment rod 15 is pushed outward from inside the sleeve 16 and connected and fixed to the knob 17. The baffle 22 on the adjustment rod 15 is used to limit its inward movement to the extreme position. Under the action of the elastic element 21, the gasket 20 always pushes the sealing ring 19, making it tightly hold the adjustment rod 15.

[0033] Furthermore, the combination of sealing ring 29, gasket 20, and elastic element 21 provides a two-way seal for adjusting rod 15. The elastic element 21 always provides stable pressure to gasket 20 and sealing ring 29, ensuring that even when adjusting rod 15 is pulled out or rotated, sealing ring 29 can still fit tightly against the rod body to achieve dynamic sealing and solve the problem of water entering the crown.

[0034] With the above structure, the entire assembly process is basically an axial pressing from top to bottom. The bottom shell 1 is "clamped" into the middle frame 2, the glass 3 is "pressed" into the middle frame 2, and the inclined surface 7 and the right-angle limiting platform 9 have good guiding and self-positioning functions, which reduces the extreme requirements for assembly accuracy and improves production efficiency and yield.

[0035] It simultaneously achieves the technical effects of being lightweight and waterproof for a ring watch, and has the advantages of compact structure and high space utilization. All structural designs are integrated into the shape of the components themselves, without the need for additional complex fasteners (such as a large number of screws), making the overall structure very compact and reserving more space for the movement 13, which is conducive to achieving a lightweight ring watch.

[0036] The cross-section of the annular protrusion 4 can be adapted to a circle or an ellipse, and the glass 3 can be polygonal, giving the product design flexibility and meeting the appearance requirements of different styles and series of ring watches.

[0037] Furthermore, adhesive is applied to the contact surfaces between the bottom shell 1, the middle frame 2, and the glass 3, which further enhances the overall assembly's connection stability and waterproofing effect.

[0038] An arc-shaped fastener 23 is provided on the side of the middle frame 2. The two ends of the arc-shaped fastener 23 are respectively fitted and connected to the two sides of the middle frame 2. The arc-shaped fastener 23 forms a ring structure, which is used by the user to wear and slip onto the user's finger.

[0039] Furthermore, the arc-shaped fastener 23 includes an elastic support (not shown) and a soft rubber layer (not shown) covering the elastic support. The elastic support can be elastic plastic to support the elastic deformation of the arc-shaped fastener 23, while the soft rubber layer can be flexible silicone, which comes into direct contact with the user's fingers. Its soft touch can prevent the user's fingers from being pressed and improve the user's comfort.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
