Description

Technical Field

[0001] This invention belongs to the technical field of watches, specifically relating to a watch and its assembly method. Background Technology

[0002] With the development of information technology, electronic consumer products are constantly evolving to meet the needs of people with different preferences. Smartwatches, in particular, are highly sought after due to their rich features and stylish appearance. However, after prolonged wear, components such as the watch case and strap of smartwatches are prone to wear and tear and cannot be replaced. Furthermore, the inability to freely replace components in smartwatches prevents users from replacing parts of the watch as needed.

[0003] Chinese patent number 201520798363.4 discloses a bezel replacement device for watches. This device can only replace the bezel and cannot disassemble the inner watch case. Chinese patent number 201821674853.3 discloses an assembled watch, but this watch has too many parts, low integration, too many mating points, and the lug mechanism is complex to install and disassemble, requiring tools. In summary, existing watches with simple structures can only have their bezels replaced; those with complex structures have many parts during assembly, making installation and disassembly quite complicated. Therefore, there is still considerable room for improvement in watch assembly. Summary of the Invention

[0004] The purpose of this invention is to provide a watch and its assembly method, which enables quick installation or disassembly of the lug mechanism, facilitating the replacement of parts and maintenance.

[0005] The technical solution is as follows:

[0006] A watch includes a bezel mechanism and a lug mechanism. The bezel mechanism has a first strap seat, and the lug mechanism has a second strap seat and a support seat. The second strap seat is mounted circumferentially on the support seat. A notch is formed between the second strap seat and the support seat. The notch is used to accommodate the first strap seat so that the outer wall of the first strap seat abuts against the inner wall of the second strap seat.

[0007] The first watch strap seat has a buckle assembly, and the support seat has at least one positioning groove in its circumferential direction, the positioning groove being used to accommodate at least a portion of the buckle assembly; the bezel mechanism is used to rotate and cooperate with the lug mechanism so that the buckle assembly cooperates with the positioning groove, and the first watch strap seat is accommodated within the notch.

[0008] In one embodiment, the snap-fit ​​assembly includes a snap-fit ​​member and an elastic member, the bezel mechanism has a mounting cavity, a first end of the elastic member is mounted on the bottom wall of the bezel mechanism and located within the mounting cavity; a second end of the elastic member is mounted on the snap-fit ​​member, and the snap-fit ​​member is at least partially located within the mounting cavity;

[0009] The snap-fit ​​component has a first movable position and a second movable position. In the first movable position, the snap-fit ​​component is at least partially located within the positioning groove, and the outer wall of the first strap seat abuts against the inner wall of the second strap seat. In the second movable position, the snap-fit ​​component is located away from the positioning groove, and the first strap seat is located outside the notch.

[0010] In one embodiment, the support base has a limiting groove extending from a first end of the support base to a second end; the latching assembly has at least two sets, wherein the latching member of one set of the latching assembly engages with the positioning groove, and the latching member of the other set of the latching assembly engages with the limiting groove; the depth of the positioning groove is less than the depth of the limiting groove, and the volume of the latching member in the positioning groove is less than the volume in the limiting groove.

[0011] In one embodiment, the snap-fit ​​member has a columnar structure and includes a guide post, a stop block, and a protrusion. The guide post, stop block, and protrusion are integrally formed. The stop block is located between the guide post and the protrusion. The elastic element is sleeved on the outside of the guide post, and there is a gap between the guide post and the top wall of the mounting cavity. The outer diameter of the stop block is larger than the outer diameter of the protrusion. The protrusion is located at the opening of the mounting cavity, and the width of the opening is smaller than the outer diameter of the stop block. The stop block is used to abut against the bottom wall of the mounting cavity.

[0012] In one embodiment, the bottom of the protrusion is spherical, the shape of the positioning groove matches the shape of the bottom of the protrusion, and the outer arc surface of the protrusion faces the bottom wall of the positioning groove and fits against the bottom wall of the positioning groove.

[0013] In one embodiment, the support base has a guide rail that extends circumferentially along the support base; the bezel mechanism has a first L-shaped groove that extends circumferentially along the bezel mechanism and engages with the guide rail.

[0014] In one embodiment, the top of the support base has a positioning element, the bottom of the bezel mechanism has a limiting groove, the limiting groove is connected to the first L-shaped groove, the positioning element is located in the limiting groove and is used to abut against the bezel mechanism.

[0015] In one embodiment, the watch further includes an inner liner mechanism, with the bezel mechanism or the support seat sleeved outside the inner liner mechanism. The bezel mechanism has a second L-shaped groove, and the support seat has a third L-shaped groove. The second L-shaped groove and the third L-shaped groove are arranged opposite to each other. The top of the inner liner mechanism is accommodated in the second L-shaped groove, and the bottom of the inner liner mechanism is accommodated in the third L-shaped groove.

[0016] In one embodiment, the inner case mechanism includes a first cover, a movement assembly, a first sealing ring, a second sealing ring, and a second cover. The movement assembly is installed inside the bezel mechanism. The top of the movement assembly has an upper opening, and the bottom of the movement assembly has a lower opening. The first cover is installed at the upper opening of the movement assembly, and the first sealing ring is installed between the outer wall of the first cover and the inner wall of the movement assembly. The second cover is installed at the lower opening of the movement assembly, and the second sealing ring is installed between the outer wall of the second cover and the inner wall of the movement assembly.

[0017] The bottom of the bezel mechanism has a groove. The inner case mechanism also includes a crown and a stem tube. The stem tube is fitted over the crown and located inside the groove. The outer wall of the stem tube is fixedly connected to the bezel mechanism. The crown is rotatably connected to the movement assembly. The crown includes a stem and a knob. The knob and the stem are integrally formed. The outer wall of the stem has at least one groove that extends circumferentially along the stem. The crown has a third sealing ring that is fitted over the stem and at least partially located within the groove. The third sealing ring is located between the inner wall of the stem tube and the outer wall of the stem.

[0018] This invention also proposes a method for assembling a watch, comprising the following steps:

[0019] Step 1: Install the buckle assembly into the mounting cavity of the first watch strap seat so that at least part of the buckle is exposed, and the inner sleeve mechanism is installed in the second L-shaped groove and the third L-shaped groove;

[0020] Step 2: Position the positioning component within the limiting groove, and allow the first L-shaped groove of the bezel mechanism to slide into the guide rail;

[0021] Step 3: Rotate the bezel mechanism. One set of buckle components slides into the positioning groove, and the other set of buckle components slides into the limiting groove. The first strap seat moves into the notch of the second strap seat, completing the installation.

[0022] The technical solution provided by this invention has the following advantages and effects:

[0023] 1. The bezel mechanism and lug mechanism rotate and engage, causing the buckle assembly of the bezel mechanism to engage with the positioning groove of the lug mechanism, thereby restricting the horizontal movement of the bezel mechanism and lug mechanism. A notch accommodates the first strap seat, causing the outer wall of the first strap seat to abut against the inner wall of the second strap seat, thus restricting the vertical movement of the bezel mechanism and lug mechanism. Vertically, the notch restricts the movement of the first strap seat; horizontally, without external force, the bezel mechanism and lug mechanism are locked in place. During installation or disassembly, only a certain torque is applied to the bezel mechanism, causing it to rotate relative to the lug mechanism, thus moving the first strap seat out of the notch and disengaging the buckle assembly from the positioning groove. This separates the bezel mechanism and lug mechanism, enabling quick installation or removal of the lug mechanism, facilitating lug mechanism replacement, and aiding in maintenance.

[0024] 2. This buckle assembly has an elastic element and a snap-fit ​​element. By rotating the bezel mechanism, the snap-fit ​​element presses against the inner wall of the positioning groove. The positioning groove applies a reverse force to the snap-fit ​​element, causing the snap-fit ​​element to press against the elastic element. The snap-fit ​​element moves into the mounting cavity and is located outside the positioning groove, thus separating the first watch strap seat from the second watch strap seat. By rotating the bezel mechanism, the snap-fit ​​element has a first moving position and a second moving position. In the first moving position, the snap-fit ​​element snaps into the positioning groove, and the first watch strap seat is snapped into the second watch strap seat and located in the notch. This bezel mechanism is fixed with the lug mechanism, completing the installation. In the second moving position, the snap-fit ​​element separates from the positioning groove, and the first watch strap seat moves out of the notch. This bezel mechanism separates from the lug mechanism, completing the disassembly.

[0025] 3. To improve the structural stability of this watch, a limiting groove is provided on the support base. The limiting groove extends from the first end of the support base to the second end. Two sets of snap-fit ​​components engage with the positioning groove and the limiting groove respectively. Because the limiting groove extends through the support base, the depth of the positioning groove is less than the depth of the limiting groove, making the volume of the snap-fit ​​component in the positioning groove smaller than that in the limiting groove. During use, the positioning groove initially secures the snap-fit ​​component, while the limiting groove limits its movement. Without external force, the snap-fit ​​component is engaged within the limiting groove. When disassembling the watch, simply push the snap-fit ​​component at the second end of the support base to move it into the mounting cavity, then rotate the bezel mechanism to separate the snap-fit ​​component from the support base. This completes the disassembly of the bezel mechanism and lug mechanism, further improving the watch's structural stability.

[0026] 4. This snap-fit ​​component uses guide posts to confine part of the snap-fit ​​component within the mounting cavity, while a protruding post allows the other part of the snap-fit ​​component to extend outside the mounting cavity. The guide posts also ensure a stable connection between the snap-fit ​​component and the elastic element, providing guidance and improving the stability of the snap-fit ​​component's movement. When the bezel mechanism rotates, the inner wall of the positioning groove presses against the protruding post, which in turn presses against the elastic element via the guide post, causing the snap-fit ​​component to move towards the mounting cavity. When the protruding post is above the positioning groove, the elastic element applies force, causing the protruding post to abut against the bottom wall of the positioning groove, thus restricting the movement of the protruding post. Furthermore, a stop block restricts the snap-fit ​​component, preventing it from moving completely outside the mounting cavity. The protruding post moves up and down within the opening, further improving the stability of the snap-fit ​​assembly.

[0027] 5. The bottom of this protrusion is spherical, and the shape of the positioning groove matches the shape of the top of the protrusion. When the bezel mechanism is rotated, the outer wall of this protrusion abuts against the bottom wall of the positioning groove, thereby generating a frictional force. When the torque generated by the rotation is greater than the frictional force, the protrusion moves out from the bottom wall of the positioning groove and squeezes the elastic element through the protrusion. The protrusion moves towards the mounting cavity, causing the snap-fit ​​element to disengage from the positioning groove, thus separating the bezel mechanism from the lug mechanism.

[0028] 6. The guide rail cooperates with the first L-shaped groove. This guide rail guides the bezel mechanism to rotate on the lug mechanism, so that the snap-fit ​​part of the bezel mechanism moves into the positioning groove or limiting groove. Moreover, this guide rail can also restrict the horizontal movement of the bezel mechanism on the lug mechanism, further improving the stability of the bezel mechanism after assembly with the lug mechanism.

[0029] 7. By cooperating with the positioning component and the limiting groove, the bezel mechanism rotates clockwise to a certain angle, and the first end of the limiting groove will abut against the positioning component. Then, the snap-fit ​​component will cooperate with the positioning groove or the limiting groove to improve the rotation accuracy of the bezel mechanism. When the bezel mechanism rotates counterclockwise to a certain angle, the second end of the limiting groove will abut against the positioning component, and the snap-fit ​​component will separate from the positioning groove or the limiting groove to improve the convenience of watch assembly.

[0030] 8. Install the top of the inner casing mechanism into the second L-shaped groove of the bezel mechanism, and the bottom of the inner casing mechanism into the third L-shaped groove of the support base, thus fixing the inner casing mechanism within the bezel mechanism and the lug mechanism. During installation, first place the bottom of the inner casing mechanism into the third L-shaped groove of the support base, then place the bezel mechanism over the inner casing mechanism, ensuring the top of the inner casing mechanism is placed in the second L-shaped groove. Rotate the bezel mechanism to secure it to the lug mechanism.

[0031] 9. A first cover and a second cover are respectively installed on the upper and lower openings of the movement assembly. A first sealing ring seals the gap between the first cover and the movement assembly, and a second sealing ring seals the gap between the second cover and the movement assembly, preventing water from entering the openings and improving the water resistance of the movement assembly. Furthermore, a third sealing ring is provided between the crown and the stem. The crown is rotatably connected to the movement assembly and is used to adjust the minute hand of the movement assembly. A groove is provided on the outer wall of the crown stem, and the third sealing ring is placed in the groove to seal the gap between the outer wall of the crown stem and the inner wall of the stem, thereby preventing water from entering the movement assembly without affecting the knob's operation of the movement assembly via the stem.

[0032] 10. This assembly method allows for quick installation of the bezel mechanism and lug mechanism, facilitating the replacement of watch parts and maintenance. Attached Figure Description

[0044] To facilitate understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0045] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0046] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0047] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0048] like Figures 1 to 6As shown, a watch 100 includes a bezel mechanism 1 and a lug mechanism 2. The bezel mechanism 1 has a first strap seat 11, and the lug mechanism 2 has a second strap seat 21 and a support seat 25. The second strap seat 21 is mounted circumferentially on the support seat 25, and a notch 211 is formed between the second strap seat 21 and the support seat 25. The notch 211 is used to accommodate the first strap seat 11 so that the outer wall of the first strap seat 11 abuts against the inner wall of the second strap seat 21. The first strap seat 11 has a buckle assembly 4, and the support seat 25 has three positioning grooves 22 circumferentially. The positioning grooves 22 are used to accommodate at least a portion of the buckle assembly 4. The bezel mechanism 1 is used to rotate and engage with the lug mechanism 2 so that the buckle assembly 4 engages with the positioning grooves 22, and the first strap seat 11 is accommodated in the notch 211. The bezel mechanism 1 and the lug mechanism 2 rotate and engage, causing the buckle assembly 4 of the bezel mechanism 1 to engage with the positioning groove 22 of the lug mechanism 2, thereby restricting the horizontal movement of the bezel mechanism 1 and the lug mechanism 2. A notch 211 accommodates the first strap seat 11, causing the outer wall of the first strap seat 11 to abut against the inner wall of the second strap seat 21, thus restricting the vertical movement of the bezel mechanism 1 and the lug mechanism 2. Vertically, the notch 211 restricts the movement of the first strap seat 11; horizontally, without external force, the bezel mechanism 1 and the lug mechanism 2 are locked together. During installation or disassembly, only a certain torque is applied to the bezel mechanism 1, causing it to rotate relative to the lug mechanism 2, so that the first strap seat 11 moves out of the notch 211 and the buckle assembly 4 disengages from the positioning groove 22. This separates the bezel mechanism 1 from the lug mechanism 2, enabling quick installation or disassembly of the lug mechanism 2, facilitating replacement of the lug mechanism 2, and aiding in maintenance.

[0049] In this embodiment, there are four second strap seats 21, and the number of first strap seats 11 corresponds to the number of second strap seats 21. Two of the second strap seats 21 are located at the six o'clock position of the support base 25, and the other two are located at the twelve o'clock position of the support base 25. A first mounting position 10 is formed between two of the second strap seats 21, and a second mounting position 20 is formed between the other two. Both the first mounting position 10 and the second mounting position 20 are used to install the watch strap. Moreover, by using four second strap seats 21, when the bezel mechanism 1 is engaged with the lug mechanism 2 via the buckle assembly 4, the inner walls of the four second strap seats 21 abut against the outer walls of the four first strap seats 11, further improving the structural stability of the watch 100.

[0050] In addition, each of the four first strap seats 11 is equipped with a buckle assembly 4, each of the three second strap seats 21 is equipped with a positioning groove 22, and the remaining second strap seat 21 is equipped with a limiting groove 23. The three sets of buckle assemblies 4 are used to engage with the three positioning grooves 22. The positioning grooves 22 are used to position the bezel mechanism 1 on the lug mechanism 2 and provide a certain limiting effect, improving the stability of the engagement between the bezel mechanism 1 and the lug mechanism 2. The limiting groove 23 is used to lock the buckle assembly 4, preventing the buckle assembly 4 from disengaging from the positioning groove 22 or the limiting groove 23 even when the bezel mechanism 1 is rotated, further improving the connection stability between the bezel mechanism 1 and the lug mechanism 2. During disassembly, a push pin is used at the bottom of the support base 25 to press the protrusion 423 of the limiting groove 23, causing the protrusion 423 to move into the mounting cavity 13. Then, the bezel mechanism 1 is rotated to complete the disassembly. The protrusion 423 of the buckle assembly 4 is hiddenly engaged in the positioning groove 22 and the limiting groove 23, which can also improve the aesthetics and decorative effect of the watch 100.

[0051] like Figure 5 , Figure 6 as well as Figure 9 As shown, the buckle assembly 4 includes a snap-fit ​​member 42 and an elastic member 41. The bezel mechanism 1 has a mounting cavity 13. The first end of the elastic member 41 is mounted on the bottom wall of the bezel mechanism 1 and located within the mounting cavity 13. The second end of the elastic member 41 is mounted on the snap-fit ​​member 42, and the snap-fit ​​member 42 is at least partially located within the mounting cavity 13. The snap-fit ​​member 42 has a first moving position and a second moving position. In the first moving position, the snap-fit ​​member 42 is at least partially located within the positioning groove 22, and the outer wall of the first strap seat 11 abuts against the inner wall of the second strap seat 21. In the second moving position, the snap-fit ​​member 42 is away from the positioning groove 22, and the first strap seat 11 is located outside the notch 211. By rotating the bezel mechanism 1, the snap-fit ​​member 42 presses against the inner wall of the positioning groove 22, and the positioning groove 22 applies a reverse force to the snap-fit ​​member 42, thereby causing the snap-fit ​​member 42 to press against the elastic member 41. The snap-fit ​​member 42 moves into the mounting cavity 13, thus separating the first strap seat 11 from the second strap seat 21. By rotating the bezel mechanism 1, the snap-fit ​​component 42 has a first moving position and a second moving position. In the first moving position, the snap-fit ​​component 42 snaps into the positioning groove 22, and the first strap seat 11 is snapped into the second strap seat 21 and located in the notch 211. This bezel mechanism 1 is fixed with the lug mechanism 2, and the installation is completed. In the second moving position, the snap-fit ​​component 42 separates from the positioning groove 22, and the first strap seat 11 moves out of the notch 211. This bezel mechanism 1 is separated from the lug mechanism 2, and the disassembly is completed.

[0052] like Figure 5 and Figure 9As shown, the support base 25 has a limiting groove 23, which extends from the first end of the support base 25 to the second end of the support base 25. In this embodiment, the first end of the support base 25 is located at the top of the support base 25, and the second end of the support base 25 is located at the bottom of the support base 25. The latching assembly 4 has at least two sets, in which the latching member 42 of one set of latching assembly 4 cooperates with the positioning groove 22, and the latching member 42 of the other set of latching assembly 4 cooperates with the limiting groove 23. The depth of the positioning groove 22 is less than the depth of the limiting groove 23, and the volume of the latching member 42 in the positioning groove 22 is less than the volume in the limiting groove 23. To improve the structural stability of the watch 100, a limiting groove 23 is provided on the support base 25. The limiting groove 23 extends from the first end of the support base 25 to the second end. Two sets of latching components 4 are used to engage with the positioning groove 22 and the limiting groove 23 respectively. Since the limiting groove 23 extends through the support base 25, the depth of the positioning groove 22 is less than the depth of the limiting groove 23, making the volume of the latching component 42 in the positioning groove 22 smaller than the volume in the limiting groove 23. During use, the positioning groove 22 initially limits the latching component 42, and the limiting groove 23 limits the latching component 42. Without external force, the latching components 4 are engaged within the limiting groove 23. When disassembling the watch 100, it is only necessary to push the latching component 42 at the second end of the support base 25 and then rotate the bezel mechanism 1 to separate the latching components 4 from the support base 25, thus completing the disassembly of the bezel mechanism 1 and the lug mechanism 2.

[0053] like Figure 9As shown, the snap-fit ​​component 42 has a columnar structure. The snap-fit ​​component 42 includes a guide post 421, a stop block 422, and a protrusion 423. The guide post 421, the stop block 422, and the protrusion 423 are an integral structure. The stop block 422 is located between the guide post 421 and the protrusion 423. The elastic element 41 is sleeved on the outside of the guide post 421, and there is a gap between the guide post 421 and the top wall of the mounting cavity 13. The outer diameter of the stop block 422 is larger than the outer diameter of the protrusion 423. The protrusion 423 is located at the opening 131 of the mounting cavity 13. The width of the opening 131 is smaller than the outer diameter of the stop block 422. The stop block 422 is used to abut against the bottom wall of the mounting cavity 13. The snap-fit ​​component 42 is partially confined within the mounting cavity 13 by the guide post 421, while the other part extends out of the mounting cavity 13 via the protrusion 423. The guide post 421 also ensures a stable connection between the snap-fit ​​component 42 and the elastic element 41, improving the stability of the snap-fit ​​component 42's movement. When the bezel mechanism 1 is rotated, the inner wall of the positioning groove 22 presses against the protrusion 423, which in turn presses against the elastic element 41 via the guide post 421, causing the snap-fit ​​component 42 to move towards the mounting cavity 13. When the protrusion 423 is above the positioning groove 22, the elastic element 41 applies force, causing the protrusion 423 to abut against the bottom wall of the positioning groove 22, thus restricting the movement of the protrusion 423. Furthermore, by restricting the snap-fit ​​component 42 by the stop block 422, the snap-fit ​​component 42 is prevented from being completely removed from the mounting cavity 13, allowing the protrusion 423 to move up and down at the position of the through 131, thereby further improving the stability of the snap-fit ​​assembly 4 in use.

[0054] like Figure 6 and Figure 9 As shown, the bottom of the protrusion 423 is spherical, and the shape of the positioning groove 22 matches the shape of the bottom of the protrusion 423. The outer arc surface of the protrusion 423 faces the bottom wall of the positioning groove 22 and fits against the bottom wall of the positioning groove 22. When the bezel mechanism 1 is rotated, the outer wall of the protrusion 423 abuts against the bottom wall of the positioning groove 22, thereby generating a frictional force. When the torque generated by the rotation is greater than the frictional force, the protrusion 423 moves out from the bottom wall of the positioning groove 22 and squeezes the elastic member 41 through the protrusion 423. The protrusion 423 moves towards the mounting cavity 13, causing the snap-fit ​​member 42 to disengage from the positioning groove 22, thus separating the bezel mechanism 1 from the lug mechanism 2.

[0055] like Figures 3 to 6As shown, the support base 25 has a guide rail 24 extending circumferentially along the support base 25; the bezel mechanism 1 has a first L-shaped groove 15 extending circumferentially along the bezel mechanism 1, and the first L-shaped groove 15 cooperates with the guide rail 24. Through the cooperation of the guide rail 24 and the first L-shaped groove 15, the guide rail 24 can guide the bezel mechanism 1 to rotate on the lug mechanism 2, causing the snap-fit ​​part 42 of the bezel mechanism 1 to move into the positioning groove 22 or the limiting groove 23; moreover, this guide rail 24 can also restrict the horizontal movement of the bezel mechanism 1 on the lug mechanism 2, further improving the stability of the bezel mechanism 1 after assembly with the lug mechanism 2.

[0056] like Figure 3 and Figure 4 As shown, the top of the support base 25 has a positioning element 26, and the circumferential bottom of the bezel mechanism 1 has a limiting groove 14. The limiting groove 14 is connected to the first L-shaped groove 15, allowing the guide rail 24 to move back and forth between the first L-shaped groove 15 and the limiting groove 14, thus avoiding limiting the rotation range of the bezel mechanism 1. The positioning element 26 is located within the limiting groove 14 and is used to abut against the bezel mechanism 1. With the positioning element 26 cooperating with the limiting groove 14, when the bezel mechanism 1 rotates clockwise to a certain angle, the first end of the limiting groove 14 will abut against the positioning element 26, and the locking element 42 will cooperate with the positioning groove 22 or the limiting groove 23 to improve the rotation accuracy of the bezel mechanism 1. When the bezel mechanism 1 rotates counterclockwise to a certain angle, the second end of the limiting groove 14 will abut against the positioning element 26, and the locking element 42 will separate from the positioning groove 22 or the limiting groove 23, improving the ease of assembly of the watch 100.

[0057] like Figure 3 , Figure 5 as well as Figure 6 As shown, the watch 100 also has an inner case mechanism 3, with a bezel mechanism 1 or a support base 25 fitted over the inner case mechanism 3. The bezel mechanism 1 has a second L-shaped groove 16, and the support base 25 has a third L-shaped groove 27. The second L-shaped groove 16 and the third L-shaped groove 27 are arranged opposite to each other. The top of the inner case mechanism 3 is accommodated in the second L-shaped groove 16, and the bottom of the inner case mechanism 3 is accommodated in the third L-shaped groove 27. The top of the inner case mechanism 3 is installed in the second L-shaped groove 16 of the bezel mechanism 1, and the bottom of the inner case mechanism 3 is installed in the third L-shaped groove 27 of the support base 25, so that the inner case mechanism 3 is fixed in the bezel mechanism 1 and the lug mechanism 2. During installation, first place the bottom of the inner case mechanism 3 in the third L-shaped groove 27 of the support base 25, then fit the bezel mechanism 1 over the inner case mechanism 3, so that the top of the inner case mechanism 3 is placed in the second L-shaped groove 16, and rotate the bezel mechanism 1 to fix the bezel mechanism 1 and the lug mechanism 2.

[0058] like Figure 7 and 8As shown, the inner case mechanism 3 includes a first cover 31, a movement assembly 33, a first sealing ring 32, a second sealing ring 36, and a second cover 37. The movement assembly 33 is installed inside the bezel mechanism 1. The top of the movement assembly 33 has an upper opening, and the bottom of the movement assembly 33 has a lower opening. The first cover 31 is installed at the upper opening of the movement assembly 33, and the first sealing ring 32 is installed between the outer wall of the first cover 31 and the inner wall of the movement assembly 33. The second cover 37 is installed at the lower opening of the movement assembly 33, and the second sealing ring 36 is installed between the outer wall of the second cover 37 and the inner wall of the movement assembly 33. In this embodiment, the dial 39 is installed inside the movement assembly 33 through the upper opening of the movement assembly 33. The first cover 31 and the second cover 37 are respectively installed in the upper and lower openings of the movement assembly 33. The gap between the first cover 31 and the movement assembly 33 is sealed by the first sealing ring 32, and the gap between the second cover 37 and the movement assembly 33 is sealed by the second sealing ring 36, so as to prevent water stains from entering the opening and the dial 39, thereby improving the waterproof performance of the movement assembly 33.

[0059] In addition, the bottom of the bezel mechanism 1 has a slot 12, and the inner tube mechanism 3 also includes a crown 35 and a stem 34. The stem 34 is sleeved on the outside of the crown 35 and is located inside the slot 12. The outer wall of the stem 34 is fixedly connected to the bezel mechanism 1, and the crown 35 is rotatably connected to the movement assembly 33. The crown 35 includes a stem 352 and a knob 351. The knob 351 and the stem 352 are an integral structure. The outer wall of the stem 352 has at least one groove 3521. The groove 3521 extends circumferentially along the stem 352. The crown 35 has a third sealing ring 38. The third sealing ring 38 is sleeved on the outside of the stem 352 and is at least partially located inside the groove 3521. The third sealing ring 38 is located between the inner wall of the stem 34 and the outer wall of the stem 352. A third sealing ring 38 is provided between the crown 35 and the stem 34. The crown 35 is rotatably connected to the movement assembly 33. The crown 35 is used to adjust the minute hand of the dial 39 of the movement assembly 33. By providing a groove 3521 on the outer wall of the crown 35's stem 352 and placing the third sealing ring 38 in the groove 3521, the gap between the outer wall of the stem 352 and the inner wall of the stem 34 is sealed, thereby preventing water stains outside the stem 352 from entering the movement assembly 33 without affecting the knob 351's drive of the movement assembly 33 via the stem 352. Therefore, by using the first sealing ring 32, the second sealing ring 36, and the third sealing ring 38 to seal the dial 39 inside the movement assembly 33 from different directions, the water resistance rating of the watch 100 is further improved.

[0060] like Figures 1 to 9 As shown, the present invention also proposes a method for assembling a watch 100, comprising the following steps:

[0061] Step 1: Install the buckle assembly 4 into the mounting cavity 13 of the first watch strap seat 11 so that the snap fastener 42 is at least partially exposed, and the inner sleeve mechanism 3 is installed in the second L-shaped groove 16 and the third L-shaped groove 27.

[0062] Step 2: Position the positioning component 26 within the limiting groove 14, and slide the first L-shaped groove 15 of the bezel mechanism 1 with the guide rail 24.

[0063] Step 3: Rotate the bezel mechanism 1. The snap fastener 42 of one set of buckle components 4 slides into the positioning groove 22, and the snap fastener 42 of the other set of buckle components 4 slides into the limiting groove 23. The first strap seat 11 moves into the notch 211 of the second strap seat 21, completing the installation.

[0064] The disassembly of watch 100 includes the following steps:

[0065] Step 1: Use a tool pin to extend from the top of the support base 25 into the limiting groove 23 and squeeze the protrusion 423 in the limiting groove 23, so that the protrusion 423 moves toward the mounting cavity 13, and the snap-fit ​​part 42 of another set of snap-fit ​​components 4 is disengaged from the limiting groove 23.

[0066] Step 2: Rotate the bezel mechanism 1. The bottom wall of the positioning groove 22 presses against the protrusion 423. The protrusion 423 moves toward the mounting cavity 13, causing the snap-fit ​​part 42 of one of the snap-fit ​​components 4 to disengage from the positioning groove 22, thus completing the disassembly.

[0067] This assembly method allows for quick installation of the bezel mechanism 1 and the lug mechanism 2, facilitating the replacement of watch 100 parts and maintenance. Furthermore, during disassembly, simply pressing the protrusion 423 moves it from the limiting groove 23 into the mounting cavity 13, and then rotating the bezel mechanism 1 allows for the removal of the lug mechanism 2. Both installation and disassembly are quite convenient.

[0068] The above embodiments are not an exhaustive list based on the present invention, and there may be many other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
