This ring structure 1 before watchcase is applicable to in the diving watch, this ring structure 1 before watchcase includes casing 11 and rotatory front bezel 12, is provided with first buckle 110 and installation position 113 on casing 11, and first buckle 110 sets up along the circumference of casing to be located the top of installation position 113, the bottom of rotatory front bezel 12 is held and is located installation position 113, is equipped with on the inner wall of this rotatory front bezel 12 with first buckle 110 complex second buckle 121. During assembly, the rotating front ring 12 needs to be pushed forward along the direction of the shell 11, the second buckle 121 arranged on the rotating front ring 12 contacts the first buckle 110 and extrudes the first buckle 110, so that the first buckle 110 is buckled, the buckling of the rotating front ring 12 and the shell 11 is realized, during disassembly, only the rotating front ring 12 needs to be pushed, the second buckle 121 is separated from the buckling of the first buckle 110, and the disassembly of the rotating front ring 12 and the shell 11 is realized.

Compared with the prior art, the watchcase front ring structure 1 provided by the invention has the advantages that the shell 11 and the rotary front ring 12 are matched with the first buckle 110 through the second buckle 121, so that the clamping connection between the rotary front ring 12 and the shell 11 is realized, and when the watchcase front ring structure is disassembled, only the rotary front ring 12 needs to be pushed, so that the second buckle 121 is separated from the buckling connection with the first buckle 110, the rotary front ring 12 and the shell 11 are convenient to disassemble, and the technical problem that the rotary front ring 12 and the watchcase are difficult to disassemble is solved.

Specifically, the mounting position 113 on the housing 11 is a groove opened on the housing 11, the front rotating ring 12 is annularly disposed in the groove, the first buckle 110 is located above the groove and extends toward the front rotating ring 12, and the second buckle 121 is disposed on the inner circumferential wall of the front rotating ring 12 and extends toward the housing 11.

Specifically, the guiding surface 1210 is a slope that inclines away from the housing 11, and the slope is used to resolve the force applied during assembly, so as to avoid crushing other parts due to excessive force applied during assembly.

In an embodiment of the present invention, referring to fig. 3 to 5, the first clip 110 and the second clip 121 are both continuous ring-shaped members, which facilitates processing the first clip 110 and the second clip 121.

In another embodiment of the present invention, the difference from the above embodiment is that the first clip 110 is a continuous ring-shaped member, or the second clip 121 is a continuous ring-shaped member. That is, when the first latch 110 is a continuous ring-shaped member, the second latch 121 is an intermittent ring-shaped member, and when the second latch 121 is pressed, the second latch 121 can be deformed greatly, which facilitates the detachment and assembly between the housing 11 and the front rotary ring 12. Or, when the first buckle 110 is an intermittent ring-shaped member, the second buckle 121 is a continuous ring-shaped member, and when the first buckle 110 is pressed, the first buckle 110 can be largely deformed, so that the detachment and assembly between the housing 11 and the rotary front ring 12 are facilitated.

Specifically, the longitudinal cross-sectional shape of the first clip 110 is L-shaped, and the longitudinal cross-sectional shape of the second clip 121 is inverted L-shaped.

In another embodiment of the present invention, further referring to FIG. 6, first catch 110 and second catch 121 are each discontinuous rings. First buckle 110 and second buckle 121 are both set to discontinuous ring-shaped members, so that when pressed, first buckle 110 and second buckle 121 can be greatly deformed, and the cooperation of the first buckle 110 and the second buckle 121 is facilitated.

It can be understood that the first buckle 110 is provided with a notch, and the second buckle 121 is also provided with a notch, so that the first buckle 110 and the second buckle 121 are discontinuous rings. When the notch is larger, the pressing force is small, and the fitting between the first catch 110 and the second catch 121 can be facilitated better.

In an embodiment of the present invention, referring to fig. 7 to 9, in order to facilitate the unidirectional rotation of the front rotating ring 12, a plurality of ratchet teeth 122 are disposed on an inner wall of the front rotating ring 12, the plurality of ratchet teeth 122 are disposed at intervals along a circumferential direction of the front rotating ring 12, tips 1221 of the plurality of ratchet teeth 122 deflect toward the same direction, the front case ring structure 1 further includes an elastic member 13, a first end of the elastic member 13 is connected to the case 11, and a second end of the elastic member 13 is inserted into an interval between two adjacent ratchet teeth 122 and abuts against the ratchet teeth 122 for preventing the front rotating ring 12 from being reversed.

Specifically, the cooperation between the elastic member 13 and the ratchet 122 of the front rotating ring 12 can be similar to a ratchet mechanism including a ratchet and a pawl, and the ratchet mechanism is mainly matched with the ratchet and the pawl so as to form a unidirectional intermittent motion mechanism, wherein the front rotating ring 12 is similar to the ratchet, the elastic member 13 is similar to the pawl, and the elastic member 13 is matched with the ratchet 122. When the front ring 12 is rotated counterclockwise, the elastic members 13 sequentially slide over the respective ratchet teeth 122, so that when the front ring 12 is rotated counterclockwise, a sound is generated. When rotatory preceding circle 12 of clockwise rotation, because elastic component 13 and ratchet 122 butt, lead to rotatory preceding circle 12 can't rotate clockwise, can only anticlockwise rotate, and seted up the scale before rotatory on the circle 12, even touch rotatory preceding circle 12 carelessly, lead to rotatory preceding circle 12 to rotate, because this rotatory preceding circle 12 can only anticlockwise rotate, can only make the predetermined time shorten and can not lengthen, thereby prevented that the mistake from bumping rotatory preceding circle 12 during underwater operation and leading to the change of calculating time and influence diver's judgement correct time, consequently can not lead to life danger.

In an embodiment of the present invention, referring to fig. 7 to 9, the housing 11 is provided with a positioning hole 111, and the first end of the elastic element 13 extends into the positioning hole 111, so that the elastic element 13 can be fixed on the housing 11, and the elastic element 13 is prevented from being separated when the front ring 12 is rotated, and cannot perform a one-way limiting function. Specifically, the elastic element 13 includes a main body portion 131 and a bending portion 132, the main body portion 131 is disposed around the front rotating ring 12, the bending portion 132 is bent and extended from one end of the main body portion 131 toward the housing 11, the bending portion 132 is inserted into the positioning hole 111, and one end of the main body portion 131 away from the bending portion 132 abuts against the ratchet 122 of the front rotating ring 12.

Further, referring to fig. 2, the 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 are not changed, and the elastic coefficient is a fixed value. Since the elastic member 13 is arc-shaped, when the front ring 12 is rotated clockwise, the elastic member 13 is arc-shaped, and the force applied to the elastic member 13 is not parallel to the axis of the elastic member 13, even if the arc-shaped elastic member 13 is pressed clockwise, the elastic member 13 cannot be compressed, so that the elastic member 13 can restrict the front ring 12 from rotating clockwise.

Of course, in other embodiments, referring to fig. 9, the elastic member 13 is an arc-shaped elastic sheet, that is, the cross-sectional shape of the elastic member 13 is a sheet. Since the elastic member 13 has an arc shape, when the front turn 12 is rotated clockwise, the elastic member 13 receives a force not parallel to the axis of the elastic member 13 because the elastic member 13 has an arc shape, so that even if the arc-shaped elastic member 13 is pressed, the elastic member 13 cannot be compressed, thereby restricting the front turn 12 from being rotated clockwise.

Further, referring to fig. 8 and 9, a guide portion 112 for guiding the elastic member 13 to be installed is disposed on a wall of the positioning hole 111, and when the elastic member 13 is assembled, the elastic member 13 slides into the positioning hole 111 under the guiding action of the guide portion 112, so that the elastic member 13 is conveniently inserted into the positioning hole 111, and the assembly efficiency is improved.

Specifically, the guide portion 112 is a chamfer extending radially outward from the hole wall of the positioning hole 111, and by forming the chamfer, on one hand, a guiding effect can be achieved, so that the elastic member 13 slides into the positioning hole 111 under the guiding effect of the guide portion 112 during assembly, and on the other hand, the elastic member 13 is prevented from being scratched during assembly.

In another embodiment of the present invention, referring to fig. 7 to 9, the front rotating ring 12 is provided with a receiving groove 123 for receiving the elastic element 13, so as to prevent the elastic element 13 from being popped off. During installation, the elastic element 13 may be pre-installed in the accommodating groove 123 to form a whole, and then the front rotating ring 12 and the elastic element 13 are placed above the housing 11, so that the front rotating ring 12 and the elastic element 13 are conveniently pressed into the housing 11 due to the guiding surface 1210 provided on the second buckle 121. At the time of disassembly, the elastic member 13 is disassembled together with the front rotary ring 12 and remains in the accommodation groove 123, thereby ensuring that the elastic member 13 is not easily flicked off.

Referring to fig. 1, 2 and 9, the invention further provides a diving watch, which includes the front case ring structure 1 in any of the above embodiments, the diving watch further includes a watch glass 2 and a bottom cover 3, the watch glass 2 is installed in the front rotary ring 12 and is abutted against the inner wall of the front rotary ring 12, and the bottom cover 3 is disposed on one side of the casing 11 far away from the front rotary ring 12 and is connected with the casing 11.

The diving watch provided by the invention adopts the watchcase front ring structure 1, the shell 11 and the rotary front ring 12 are matched with the first buckle 110 through the second buckle 121, so that the clamping between the rotary front ring 12 and the shell 11 is realized, and when the diving watch is disassembled, only the rotary front ring 12 needs to be pushed, so that the second buckle 121 is separated from the buckling with the first buckle 110, the rotary front ring 12 and the shell 11 are convenient to disassemble, and the technical problem that the rotary front ring 12 and the watchcase are difficult to disassemble is solved.

Furthermore, the diving meter also comprises a helium discharge valve 4, the helium discharge valve 4 is screwed with the shell 11, when in deep sea operation, a diver needs to expect that the air in the diving chamber is helium-oxygen mixed gas, helium molecules enter from a tiny gap of the watch in the high-pressure chamber due to small molecular volume, when the diver rises to the water surface, the external pressure suddenly reduces, the high-pressure helium gas in the diving meter cannot be discharged in short time, the imbalance of the internal air pressure and the external air pressure causes the burst of the diving meter, and the helium gas in the shell 11 can be rapidly discharged by rotating the helium discharge valve 4, so that the safety of the diving meter is ensured.

Specifically, the anti-slip member 41 is disposed on the helium discharge valve 4, the anti-slip member 41 facilitates the manual rotation of the helium discharge valve 4, and preferably, the anti-slip member 41 is a plurality of anti-slip protrusions disposed on the circumference of the helium discharge valve 4, and the manual rotation of the anti-slip protrusions facilitates the loosening or tightening of the helium discharge valve 4.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
