Technical Field

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

[0002] A watch, also known as a wristwatch, is an instrument worn on the wrist to tell time. Watches typically use materials such as leather, rubber, nylon, or stainless steel to make the watch strap, which secures the watch face to the wrist.

[0026] Please see Figures 1 to 5 One embodiment of this utility model is a waterproof structure for a wristwatch, comprising a bottom case 1, an annular shell 2, a cover 3, and a high-transparency glass 4. The overall structure is designed to achieve efficient waterproofing through multiple sealing methods.

[0027] The bottom shell 1 has an annular protrusion 11, the top of which extends outward to form a surrounding edge 12. A sealing ring 13 with an elliptical cross-section is fitted around the annular protrusion 11, and the sealing ring 13 is located at the bottom of the surrounding edge 12. The inner side of the bottom of the annular shell 2 has a first annular recess 21. During assembly, the annular protrusion 11 is embedded in it, the surrounding edge 12 is in close contact with the inner wall of the annular shell 2, and at the same time, the sealing ring 13 and the first annular recess 21 are pressed together to form the first sealing barrier, realizing the sealed connection between the bottom shell 1 and the annular shell 2, and improving the waterproof effect of the overall structure.

[0028] The bottom of the cover 3 is provided with an annular protrusion 31, which is embedded in the top of the annular shell 2 for positioning; the cover 3 is also provided with a first annular groove 32, which contains a second sealing ring 33 with an elliptical cross section. After assembly, the second sealing ring 33 is in close contact with the top surface of the annular shell 2 to form a second waterproof seal; the inner wall of the annular shell 2 is also provided with a second limiting platform 22, which is in contact with the bottom of the cover 3 and coated with glue to further strengthen the seal, thereby realizing the sealing structure between the annular shell 2 and the cover 3 and improving the waterproof effect of the overall structure.

[0029] The inner side of the cover 3 is provided with a first limiting platform 34. The high-transparency glass 4 is embedded into the cover 2 from top to bottom and abuts against the first limiting platform 34. A rectangular sealing ring 35 is provided between the outer periphery of the high-transparency glass 4 and the inner wall of the cover 3. Adhesive is applied to the interfaces on both sides to form a third layer of sealing protection, so as to achieve the sealed installation of the high-transparency glass 4 and the cover 3 and improve the waterproof effect of the overall structure.

[0030] The inner wall of the annular shell 2 is provided with an inclined surface 23 that slopes inward from top to bottom, which is adapted to and pressed tightly with the perimeter 12 of the bottom shell 1, thus enhancing the sealing reliability.

[0031] An installation cavity is provided between the bottom shell 1, the annular shell 2, the cover 3 and the high-transparency glass 4, forming a sealed installation cavity inside, which is used to assemble the movement (not shown) and the dial 6, further preventing moisture from entering.

[0032] The movement (not shown) can be a mechanical movement, which rotates through the cooperation of precision mechanical parts. The dial 6 is printed with time numerals, and the second, minute and hour hands point to specific positions to indicate the time.

[0033] If it is a mechanical movement, a through hole 24 is provided on the side of the annular housing 2. An adjustment component 5 is installed on the through hole 24. The adjustment component 5 includes an adjustment rod 51 and a sleeve 52. The adjustment rod 51 is provided with a second annular groove 53. The second annular groove 53 is provided with a sealing ring 54. The sleeve 52 is sleeved with the adjustment rod 51, and the sealing ring 54 abuts against the inner wall of the sleeve 52. The sleeve 52 is embedded in the through hole 24. An adjustment knob 55 is connected to the outer end of the adjustment rod 51, and the other end of the adjustment rod 51 is connected to the movement. The movement is adjusted by rotating the adjustment knob 55. The adjustment knob 55 has a space that fits the sleeve 52, and the adjustment knob 55 is provided with a second annular recess 56. The sleeve 52 is sleeved with a sealing ring 57. The sealing ring 57 abuts against the second annular recess 56 and the annular housing 2. The above assembly forms a double-layer sealing structure to prevent water from entering the installation cavity through the through hole, which could cause the movement to rust or be damaged.

[0034] The movement (not shown in the figure) can be an electronic movement, that is, the annular housing 2 does not need to have a through hole 24 and does not need to install the adjustment component 5.

[0035] The cross-sections of sealing ring 13 and sealing ring 23 are elliptical. This structure allows for greater deformation of sealing ring 13 or sealing ring 233, making it easier to fit the irregular structure between the assembly gaps, fill the assembly gaps, and further improve the sealing effect. The cross-section of sealing ring 35 is rectangular. The structure of sealing ring 35 fills the gap between the cover 3 and the high-transparency glass 4, and sealing ring 35 can increase the friction with the cover 3 or high-transparency glass 4, preventing sealing ring 35 from separating from the cover 3 or high-transparency glass 4, and further increasing the effect of stable assembly connection.

[0036] The dial 6 has two concentric annular barriers 61 and several evenly distributed protrusions 62. The protrusions 62 are located between the two annular barriers 61, and a ball bearing 63 is provided between the two annular barriers 61. The ball bearing 63 can slide freely. This structure allows the ball bearing 63 to roll between the two annular barriers 61 and stop between the two protrusions 62, which can increase the user's interest and improve the user experience.

[0037] 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.
