Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] Please also read Figures 1 to 4 Now, the watch case front ring structure 1 provided by the embodiment of the present invention is described. The watch case front ring structure 1 is suitable for use in a diving watch, and the watch case front ring structure 1 comprises a housing 11 and a rotating front ring 12. The housing 11 is provided with a first buckle 110 and a mounting position 113. The first buckle 110 is arranged along the circumference of the housing and is located above the mounting position 113. The bottom of the rotating front ring 12 is accommodated in the mounting position 113. The inner wall of the rotating front ring 12 is provided with a second buckle 121 that cooperates with the first buckle 110. During assembly, the rotating front ring 12 needs to be pushed along the direction of the shell 11, and the second buckle 121 arranged on the rotating front ring 12 contacts the first buckle 110 and squeezes the first buckle 110, thereby achieving the engagement with the first buckle 110, thereby achieving the engagement of the rotating front ring 12 and the shell 11. During disassembly, it is only necessary to push the rotating front ring 12 so that the second buckle 121 is disengaged from the first buckle 110, thereby achieving the disassembly of the rotating front ring 12 and the shell 11.

[0036] Compared with the prior art, the watch case front ring structure 1 provided by the present invention cooperates between the shell body 11 and the rotating front ring 12 through the second buckle 121 and the first buckle 110, thereby realizing the snap connection between the rotating front ring 12 and the shell body 11. When disassembling, it is only necessary to push the rotating front ring 12 so that the second buckle 121 is disengaged from the snap connection with the first buckle 110, thereby facilitating the disassembly of the rotating front ring 12 and the shell body 11, and solving the technical problem of the difficulty in disassembly between the rotating front ring 12 and the watch case.

[0037] Specifically, the mounting position 113 on the shell 11 is a groove opened on the shell 11, and the rotating front ring 12 is arranged in the groove. The first buckle 110 is located above the groove and extends toward the rotating front ring 12. The second buckle 121 is arranged on the inner wall of the rotating front ring 12 and extends toward the shell 11.

[0038] Further, see Figure 3 and Figure 4A guide surface 1210 is provided at the edge of the second buckle 121. During assembly, the second buckle 121 slides into the first buckle 110 under the guidance of the guide surface 1210, making it easy for the second buckle 121 to be buckled into the first buckle 110, thereby realizing the buckling of the rotating front ring 12 and the housing 11. Since a watch glass mounting position is also provided on the housing 11, the glass installed in the watch glass mounting position is avoided from being crushed by excessive force, thereby improving the assembly efficiency.

[0039] Specifically, the guide surface 1210 is an inclined surface that is inclined outward away from the housing 11. During assembly, the inclined surface is used to decompose the force applied during assembly, thereby preventing excessive force applied during assembly from crushing other components.

[0040] In one embodiment of the present invention, please refer to Figures 3 to 5 The first buckle 110 and the second buckle 121 are both continuous annular parts, which facilitates the processing of the first buckle 110 and the second buckle 121.

[0041] In another embodiment of the present invention, the difference from the above embodiment is that the first buckle 110 is a continuous annular member, or the second buckle 121 is a continuous annular member. That is, when the first buckle 110 is a continuous annular member, the second buckle 121 is a discontinuous annular member, and when pressed, the second buckle 121 can be greatly deformed, which is convenient for the disassembly and assembly between the housing 11 and the rotating front ring 12. Alternatively, when the first buckle 110 is a discontinuous annular member, the second buckle 121 is a continuous annular member, and when pressed, the first buckle 110 can be greatly deformed, which is convenient for the disassembly and assembly between the housing 11 and the rotating front ring 12.

[0042] Specifically, the longitudinal cross-section of the first buckle 110 is L-shaped, and the longitudinal cross-section of the second buckle 121 is inverted L-shaped.

[0043] In another embodiment of the present invention, further combined with Figure 6 The first buckle 110 and the second buckle 121 are both discontinuous annular parts. The first buckle 110 and the second buckle 121 are both set as discontinuous annular parts, so that when pressed, the first buckle 110 and the second buckle 121 can be greatly deformed, which is convenient for the cooperation between the two.

[0044] It is understandable that a notch is provided on the first buckle 110 and a notch is also provided on the second buckle 121, so that the first buckle 110 is a discontinuous annular member and the second buckle 121 is a discontinuous annular member. When the notch is larger, the pressing force is smaller, which can better facilitate the cooperation between the first buckle 110 and the second buckle 121.

[0045] In one embodiment of the present invention, see Figures 7 to 9In order to facilitate the unidirectional rotation of the rotating front ring 12, a plurality of ratchet teeth 122 are arranged on the inner wall of the rotating front ring 12. The plurality of ratchet teeth 122 are arranged at intervals along the circumference of the rotating front ring 12. The tips 1221 of the plurality of ratchet teeth 122 are deflected in the same direction. The case front ring structure 1 also includes an elastic member 13. The first end of the elastic member 13 is connected to the housing 11. The second end of the elastic member 13 is inserted into the gap between two adjacent ratchet teeth 122 and abuts against the ratchet teeth 122 to prevent the rotating front ring 12 from reversing.

[0046] Specifically, the cooperation between the elastic member 13 and the ratchet teeth 122 of the rotating front ring 12 can be analogized to a ratchet mechanism, which includes a ratchet wheel and a pawl. The ratchet mechanism mainly cooperates with the ratchet wheel and the pawl to form a unidirectional intermittent motion mechanism, wherein the rotating front ring 12 is analogized to a ratchet wheel, the elastic member 13 is analogized to a pawl, and the elastic member 13 cooperates with the ratchet teeth 122. When the rotating front ring 12 rotates counterclockwise, the elastic member 13 slides over each ratchet tooth 122 in sequence, so that a sound is emitted when the rotating front ring 12 rotates counterclockwise. When the rotating front ring 12 is rotated clockwise, the elastic member 13 abuts against the ratchet 122, so that the rotating front ring 12 cannot rotate clockwise but can only rotate counterclockwise. There is a scale on the rotating front ring 12. Even if the rotating front ring 12 is accidentally touched, causing the rotating front ring 12 to rotate, since the rotating front ring 12 can only rotate counterclockwise, the predetermined time can only be shortened but not lengthened, thereby preventing the rotating front ring 12 from being accidentally touched during underwater operations, resulting in changes in the calculated time and affecting the diver's judgment of the correct time, and thus does not cause life-threatening.

[0047] In one embodiment of the present invention, refer to Figures 7 to 9 The housing 11 is provided with a positioning hole 111, and the first end of the elastic member 13 extends into the positioning hole 111, so that the elastic member 13 can be fixed on the housing 11 to prevent the elastic member 13 from being disengaged when the rotating front ring 12 is rotated, and the elastic member 13 cannot play the role of one-way limiting. Specifically, the elastic member 13 includes a main body 131 and a bending portion 132, the main body 131 is arranged in the rotating front ring 12, the bending portion 132 is bent and extended from one end of the main body 131 toward the housing 11, and the bending portion 132 is inserted into the positioning hole 111, and the end of the main body 131 away from the bending portion 132 abuts against the ratchet 122 of the rotating front ring 12.

[0048] Further, see Figure 2The elastic member 13 is an arc-shaped linear spring, that is, the cross-sectional shape of the elastic member 13 is circular, and the thickness and density of the linear spring from top to bottom remain unchanged, and the elastic coefficient is a fixed value. Since the elastic member 13 is arc-shaped, when the rotating front ring 12 is rotated clockwise, the force it receives is not parallel to the axis of the elastic member 13, and even if the arc-shaped elastic member 13 is squeezed clockwise, the elastic member 13 cannot be compressed, so that the elastic member 13 can limit the clockwise rotation of the rotating front ring 12.

[0049] Of course, in other embodiments, see Fig. 9 The elastic member 13 is an arc-shaped spring sheet, that is, the cross-section of the elastic member 13 is in the shape of a sheet. Since the elastic member 13 is in the shape of an arc, when the rotating front ring 12 is rotated clockwise, the force received by the elastic member 13 is not parallel to the axis of the elastic member 13, so that even if the arc-shaped elastic member 13 is squeezed, the elastic member 13 cannot be compressed, thereby limiting the clockwise rotation of the rotating front ring 12.

[0050] Further, see Figure 8 and Fig. 9 A guide portion 112 for guiding the installation of the elastic member 13 is provided on the hole wall of the positioning hole 111. During assembly, the elastic member 13 slides into the positioning hole 111 under the guidance of the guide portion 112, which facilitates the insertion of the elastic member 13 into the positioning hole 111 and improves assembly efficiency.

[0051] Specifically, the guide portion 112 is a chamfer extending radially outward from the hole wall of the positioning hole 111. By providing the chamfer, on the one hand, it can play a guiding role, so that during assembly, the elastic member 13 can slide into the positioning hole 111 under the guidance of the guide portion 112. On the other hand, it can avoid scratching the elastic member 13 during the assembly process.

[0052] In another embodiment of the present invention, see Figures 7 to 9 , a receiving groove 123 for receiving the elastic member 13 is provided on the rotating front ring 12, which can prevent the elastic member 13 from being bounced away. During installation, the elastic member 13 can be pre-installed in the receiving groove 123 to form an integral body, and then the rotating front ring 12 and the elastic member 13 are placed above the housing 11. Since the second buckle 121 is provided with a guide surface 1210, it is convenient to press the rotating front ring 12 and the elastic member 13 into the housing 11. During disassembly, the elastic member 13 is removed together with the rotating front ring 12 and retained in the receiving groove 123, thereby ensuring that the elastic member 13 is not easily bounced away.

[0053] See also Figure 1 , Figure 2 and Fig. 9The present invention also provides a diving watch, which includes the case front ring structure 1 in any of the above embodiments, and also includes a watch glass 2 and a bottom cover 3. The watch glass 2 is installed in the rotating front ring 12 and abuts against the inner wall of the rotating front ring 12. The bottom cover 3 is arranged on a side of the shell 11 away from the rotating front ring 12 and is connected to the shell 11.

[0054] The diving watch provided by the present invention adopts the above-mentioned case front ring structure 1, and the case body 11 and the rotating front ring 12 are matched with the second buckle 121 and the first buckle 110, thereby realizing the snap connection between the rotating front ring 12 and the case body 11. When disassembling, it is only necessary to push the rotating front ring 12 so that the second buckle 121 is disengaged from the snap connection with the first buckle 110, thereby facilitating the disassembly of the rotating front ring 12 and the case body 11, and solving the technical problem that the rotating front ring 12 and the case body are difficult to disassemble.

[0055] Furthermore, the diving watch also includes a helium exhaust valve 4, which is screwed to the housing 11. When working in the deep sea, divers need to stay in the diving chamber for a long time. The air in the diving chamber is a helium-oxygen mixed gas. Since helium molecules have a small molecular volume, they will enter from extremely small gaps in the watch in the high-pressure chamber. When the diver rises to the surface, the external pressure drops suddenly, and the high-pressure helium in the diving watch cannot be discharged in a short time. The imbalance of internal and external air pressure will cause the diving watch to explode. The helium in the housing 11 can be quickly discharged by rotating the helium exhaust valve 4, thereby ensuring the safety of the diving watch.

[0056] Specifically, an anti-slip part 41 is provided on the helium exhaust valve 4, and the anti-slip part 41 helps a person to rotate the helium exhaust valve 4 manually. Preferably, the anti-slip part 41 is a plurality of anti-slip protrusions arranged around the helium exhaust valve 4. By providing a plurality of anti-slip protrusions, it is convenient for a person to rotate manually and to loosen or tighten the helium exhaust valve 4.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
