Description

Technical Field

[0001] The present invention relates to the technical field of watch accessories, in particular to a watch strap with a detachable decorative piece. Background Art

[0002] A watch, or wristwatch, is an instrument worn on the wrist for measuring and displaying time. In recent years, with the increasing popularity of wearable devices like watches and consumer demand for personalization, watch straps have not only fulfilled the practical function of securing the watch case but have also gradually become an important decorative element that reflects consumers' aesthetic tastes and personalities. To enhance product fashion and customizability, some watch strap designs incorporate replaceable decorative modules. These decorative elements can be easily changed to suit different usage scenarios or personal preferences, giving the device a more stylish and personalized feel.

[0003] However, in actual use, this type of watch strap still has certain defects, mainly manifested in the problem that the decorative parts are prone to warping during use and are inconvenient to disassemble and assemble. Since soft materials such as rubber and silicone have high flexibility and stretchability, although they can provide good wearing comfort, when accessories are frequently changed, the connection parts of the watch strap are easily affected by pressure and friction, resulting in warping or loosening, affecting the aesthetics and user experience. Especially after long-term wear or high-intensity exercise, the uneven local force on the watch strap may aggravate the warping problem and may even cause the accessories to loosen or fall off. In addition, in scenarios such as diving and fitness, the rubber material is easily affected by moisture, sweat or temperature changes, which further reduces the stability of the accessories and increases the risk of damage or falling of the watch strap.

[0004] In addition, there is a naturally formed gap between the decorative accessories and the strap body. Even though the existing technology has a decorative formula that is set to an interference fit between the two to minimize or eliminate the gap, after the product is used for a long time, in harsh environments or with high intensity, soft materials such as rubber and silicone will inevitably show aging phenomena such as weakening of elasticity, thereby increasing the gap between the decorative accessories and the strap body, or reducing the flatness, resulting in a decrease in the visual integrity and aesthetics of the product.

[0005] To achieve the detachable function of accessories, watch straps and accessories usually require a specialized connection structure. Some connection methods may wear, loosen, or age over long-term use, affecting the stability of the decorative parts and even causing the accessories to accidentally fall off due to a loose connection. Furthermore, currently common watch strap decorations require specialized tools to remove and replace, which is difficult to do.

[0006] Therefore, it is necessary to further optimize the connection structure between the strap and accessories to improve the convenience and stability of disassembly and assembly, and at the same time improve the strap material and structural design to enhance its tensile and compressive resistance and reduce the occurrence of warping.

[0022] In order to achieve the second object of the above invention, the present invention provides the following technical solutions:

[0023] A method for disassembling and assembling a decorative piece of a watchband having a detachable decorative piece as described above, wherein the installation of the decorative piece comprises the following steps:

[0024] S1: inserting the decorative piece into the mounting portion of the preset reinforcement piece along the extending direction of the watchband body, so that the limiting piece at the first limiting end is inserted into the limiting groove;

[0025] S2: Pressing down the decorative member, so that the limiting protrusion of the limiting member at the bottom of the first limiting end is inserted into the limiting hole of the mounting portion, and the limiting protrusion of the limiting member at the bottom of the second limiting end is inserted into the reinforcement hole and the mounting hole;

[0027] Furthermore, the disassembly of the decorative element includes the following steps:

[0028] S1: respectively withdrawing the two ends of the spring ears from the spring ear assembly holes on the groove walls on both sides of the buckling groove, and removing the decorative buckle from the mounting portion in a direction away from the decorative component;

[0029] S2: Sequentially withdraw the limiting protrusions of the limiting piece at the bottom of the second limiting end from the corresponding limiting holes and reinforcement holes; withdraw the limiting protrusions of the limiting piece at the bottom of the first limiting end from the corresponding limiting holes, and then pull the decorative piece out toward the opening direction of the mounting portion, so that the first limiting end is completely withdrawn from the limiting groove.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1) The present invention introduces a detachable decorative element into the watch strap, making it not only decorative but also flexible and allowing for the replacement of decorative elements. This provides users with more personalized options and enhances the fashion and functionality of the watch strap.

[0032] Furthermore, by arranging a limit piece at the first limit end and / or the second limit end of the decorative piece so that it is embedded in the mounting portion of the strap body, the bonding strength between the decorative piece and the mounting portion is enhanced. Even if the soft material ages and its elasticity weakens during long-term use, the limit piece can still provide additional mechanical support to ensure the stability and tight fit of the decorative piece, thereby effectively preventing the decorative piece from warping upward, loosening and falling off when the strap is bent, deformed or stressed. It can also avoid the problem of increased gaps or decreased flatness caused by aging of the soft material, maintain a good fit between the strap and the decorative piece, ensure that its appearance is not affected, and maintain its integrity and aesthetics; at the same time, it greatly improves the folding performance of the strap body, is more suitable for high-intensity usage scenarios such as sports, and improves the adaptability of the strap.

[0033] 2) The structural design of the decorative buckle of the present invention fully takes into account functionality and aesthetics. It can improve the layering of the watchband decoration by matching different styles and colors with decorative parts. At the same time, the decorative buckle is provided with a V-shaped clamping part that matches the shape of the second limiting end. The clamping part is directly covered on the outside of the second limiting end during the installation process to form a reliable clamping fit; the precise fit with the decorative parts and the limiting parts makes the fixation of the decorative parts more stable, effectively preventing the decorative parts from shifting due to use or impact, and improving the firmness of wearing and the convenience of replacing the decorative parts; on the other hand, the decorative buckle also takes over the connection function of the watchband and the watch case, realizing a close connection between the watchband and the watch case, and improving the stability during wearing.

[0034] 3) The mounting portion of the present invention adopts a V-shaped structure with its opening facing the direction of the watch case, forming a natural insertion guide for cooperating with the limiting piece and limiting protrusion at the bottom of the first limiting end of the decorative piece. A W-shaped buckle groove is further formed at the opening of the V-shaped mounting portion, and both side walls of the groove are provided with ear assembly holes for accommodating decorative buckles with pre-installed ears. This design forms multiple insertion positioning points in three-dimensional space, with the first limiting end inserted into the limiting groove and limiting hole, and the second limiting end inserted into the clamping portion. At the same time, the decorative buckle is laterally inserted into the W-shaped buckle groove to complete the overall compression and locking. The coordinated cooperation not only ensures a tight fit between the decorative piece and the watchband body, but also greatly enhances the impact resistance and deformation resistance, avoiding structural loosening due to long-term use or external pulling.

[0035] In addition, the buckling slot ensures the convenient installation of decorative parts and decorative buckles. In order to enhance the bending resistance of the watch strap, a reinforcement piece is introduced on the installation part. On the one hand, its reinforcement arms are arranged in the groove walls on both sides of the buckling slot and tightly fit with the groove walls to provide additional support for the end of the strap, effectively strengthening the structure on both sides of the buckling slot, significantly improving the structural strength of the strap, and avoiding deformation of the strap when subjected to force or bending; on the other hand, the square reinforcement plate located between the two reinforcement arms is embedded in the V-shaped clamping part of the decorative buckle to prevent the decorative buckle from loosening and shifting. Therefore, the design of the reinforcement piece not only optimizes the installation process of the decorative parts, but also ensures that the strap maintains good structural stability during long-term use and adapts to more high-intensity usage scenarios.

[0036] 4) The decorative part installation method of the present invention is easy to operate, and three-way positioning is achieved by lateral insertion of the limiting member, vertical downward pressure of the decorative member, and lateral locking of the decorative buckle: first, the first limiting end of the decorative part is laterally inserted into the limiting groove preset in the watchband mounting portion through the limiting member provided at its bottom, thereby achieving preliminary guiding and anti-warping functions; then, the decorative part is pressed downward so that the limiting protrusion of the first limiting end is inserted into the limiting hole, and at the same time, the limiting protrusion of the limiting member at the bottom of the second limiting end is simultaneously inserted into the reinforcement hole and the mounting hole on the reinforcement member, thereby achieving longitudinal compression and structural locking; finally, the decorative buckle together with the spring ear is horizontally pushed into the W-shaped buckling groove so that the V-shaped clamping portion and the second limiting end are reliably matched, and at the same time, the spring ear is inserted into the assembly holes on the two side walls of the watchband body and connected to the watch case, completing the overall installation; the overall assembly of the decorative part of the present invention ensures structural stability while reducing the difficulty of operation, and positioning and fixing can be completed quickly and accurately without auxiliary tools;

[0037] Similarly, the three-way positioning structure is also executed in reverse order during the disassembly of the decorative parts. The operator first withdraws the spring ear from the spring ear assembly hole, then pulls out the decorative buckle to loosen the clamping structure of the V-shaped clamping part; then, by pulling out the limiting protrusion of the limiting part, withdraw the second limiting end and the first limiting end from the reinforcement hole and the limiting hole in turn, and finally pulls out the decorative part as a whole along the opening direction of the installation part; the entire disassembly and assembly process is simple to operate and the mechanical path is reasonable, which greatly reduces the structural loss and appearance damage that may be caused by repeated disassembly and assembly or user misoperation.

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0050] It should be noted that the construction and arrangement of the present invention shown in various exemplary embodiments are illustrative only. Although only a few embodiments are described in detail in this disclosure, those reading this disclosure will readily appreciate that many modifications are possible (e.g., the size, structure, shape, and proportions of the various components) without materially departing from the novel teachings and advantages of the subject matter described in this application. The order or sequence of any process or method steps may be changed or reordered according to alternative embodiments.

[0051] In the description of the present invention, unless otherwise specified, all components used are conventional components in the prior art.

[0052] like Figure 1-9 As shown, the present invention provides a watch strap with a detachable decorative part, wherein the watch strap is connected to one side of the watch case, and a spring ear 10 is provided at one end of the watch strap close to the watch case, and is connected to the watch case (not shown in the drawings) through the spring ear 10; in this embodiment, the spring ear 10 is a cylindrical connecting member used in the prior art to be simultaneously passed through the watch strap and the side of the watch case to achieve fixation of the watch strap and the watch case, and is not described in detail here.

[0053] Further introduction to the strap structure, including:

[0054] The strap body 1 is an integrally formed elastic strap, and one end of the strap body 1 close to the watch case is recessed and provided with a mounting portion 11 for mounting the decorative part 2; in this embodiment, the strap body 1 can be made of fluororubber, silicone rubber or thermoplastic elastomer; in other optional embodiments, it can also be made of other materials that meet the usage scenarios of the strap body of the present invention.

[0055] The decorative piece 2 is detachably mounted on the mounting portion 11; the decorative piece 2 is provided with a first limiting end 21 and a second limiting end 22 at both ends along the extension direction of the strap body; a limiting piece 23 is provided on the first limiting end 21 and / or the second limiting end 22, and at least a portion of the limiting piece 23 is embedded in the mounting portion 11 to limit the first limiting end 21 or the second limiting end 22 of the decorative piece from warping off or falling off relative to the surface of the strap body 1 after installation.

[0056] In this embodiment, the limiting member 23 is fixed to the decorative member 2 by existing methods such as bonding; or the limiting member can be integrally formed with the decorative member, as long as the limiting member is fixed to the bottom of the first limiting end and the second limiting end of the decorative member.

[0057] like Figure 8 As shown, in one of the preferred embodiments, the main body of the limiting member at the bottom of the first limiting end extends outside the decorative member in a direction away from the watch case, and the portion extending outside the decorative member is embedded in and fixed in the mounting portion, thereby fixing the first limiting end of the decorative member in the mounting portion without exceeding the surface of the watch strap body to prevent warping or falling off.

[0058] In one preferred embodiment, the limiting member at the bottom of the second limiting end is mainly used to limit the second limiting end to the bottom of the mounting portion to avoid relative displacement, and the limiting member can be embedded in the main body of the decorative member.

[0059] The present invention introduces a detachable decorative element design into the watch strap, making the watch strap not only decorative but also flexible and replaceable, providing users with more personalized choices and improving the fashion and functionality of the watch strap.

[0060] Furthermore, by arranging a limit piece at the first limit end and / or the second limit end of the decorative piece so that it is embedded in the mounting portion of the strap body, the bonding strength between the decorative piece and the mounting portion is enhanced. Even if the soft material ages and its elasticity weakens during long-term use, the limit piece can still provide additional mechanical support to ensure the stability and tight fit of the decorative piece, thereby effectively preventing the decorative piece from warping upward, loosening and falling off when the strap is bent, deformed or stressed. It can also avoid the problem of increased gaps or decreased flatness caused by aging of the soft material, maintain a good fit between the strap and the decorative piece, ensure that its appearance is not affected, and maintain its integrity and aesthetics; at the same time, it greatly improves the folding performance of the strap body, is more suitable for high-intensity usage scenarios such as sports, and improves the adaptability of the strap.

[0061] To improve the assembly stability of the decorative element, the decorative element 2 is optionally detachably mounted on the mounting portion 11 via a decorative buckle 3. The decorative buckle 3 is used to press against the decorative element 2 in the direction away from the watch case, along the strap body 1. The end of the mounting portion 11 facing away from the watch case is provided with a retaining groove 12 for accommodating the retaining member 23 located at the bottom of the first retaining end 21. At least a portion of the retaining member 23 is laterally inserted into and secured in the retaining groove 12. The decorative buckle 3 is provided with a V-shaped clamping portion 31 that matches the second retaining end 22. The second retaining end 22 is located and secured in the clamping portion 31. In this embodiment, the end of the decorative buckle facing the watch case is provided with an arc-shaped edge that is recessed away from the edge of the watch case. Accordingly, the spring tab can also be adaptively designed with a matching arc shape.

[0062] In addition, the two side walls of the mounting portion 11 are provided with ear assembly holes 13, and the end of the decorative buckle 3 close to the watch case is provided with a connecting hole 32 corresponding to the ear assembly hole 13, and the ear is inserted into the ear assembly hole 13 and the connecting hole 32 to be connected to the watch case.

[0063] And to be further refined, a limiting protrusion 231 is provided at the bottom of the limiting member 23, and a limiting hole 14 is provided at the end of the mounting portion 11 away from the watch case, which is adapted to the limiting protrusion 231, and the limiting protrusion 231 is passed through and fixed in the limiting hole 14; the end of the mounting portion 11 close to the watch case is provided with a buckling groove 15 that passes through the upper and lower surfaces of the strap body 1, and the groove walls on both sides of the buckling groove 15 are provided with ear assembly holes 13, and the decorative buckle 3 is embedded in the buckling groove 15.

[0064] In order to improve the stability of the assembly of the raw ear 10, a reinforcement sleeve 20 is provided on the outer periphery of the raw ear 10, and a limiting column 201 is provided at the bottom of the reinforcement sleeve 20. The bottom surface of the decorative buckle 3 is provided with an adjustment hole 34 for the limiting column 201 to pass through; the limiting column 201 can move in the adjustment hole 34 and adjust the position of the raw ear.

[0065] In this embodiment, the structural design of the decorative buckle fully takes into account both functionality and aesthetics. It can improve the layering of the strap decoration by matching different styles and colors with decorative parts. At the same time, the decorative buckle is provided with a V-shaped clamping part that matches the shape of the second limiting end. The clamping part is directly covered on the outside of the second limiting end during the installation process to form a reliable clamping fit; the precise fit with the decorative parts and the limiting parts makes the fixation of the decorative parts more stable, effectively preventing the decorative parts from shifting due to use or impact, and improving the firmness of wearing and the convenience of replacing decorative parts; on the other hand, the decorative buckle also takes over the connection function between the strap and the watch case, realizes the close connection between the strap and the watch case, and improves the stability during wearing.

[0066] The structure of the mounting portion 11 is further introduced. The mounting portion 11 is a V-shaped mounting portion with its opening facing the direction of the watch case, and its width gradually decreases in the direction away from the watch case; the snap-fitting groove 15 is located at the opening of the V-shaped mounting portion 11, and the snap-fitting groove 15 is a W-shaped snap-fitting groove 15.

[0067] The mounting portion of the present invention adopts a V-shaped structure with its opening facing the direction of the watch case, forming a natural insertion guide for cooperating with the limiting member and limiting protrusion at the bottom of the first limiting end of the decorative piece. A W-shaped buckle groove is further formed at the opening of the V-shaped mounting portion, and both side groove walls are provided with ear assembly holes for accommodating decorative buckles with pre-installed ears. This design forms multiple insertion positioning points in three-dimensional space. The first limiting end is inserted into the limiting groove and limiting hole, and the second limiting end is inserted into the clamping portion. At the same time, the decorative buckle is inserted horizontally into the W-shaped buckle groove to complete the overall compression and locking. The coordinated cooperation not only ensures a tight fit between the decorative piece and the watchband body, but also greatly enhances the impact resistance and deformation resistance, avoiding structural loosening due to long-term use or external pulling.

[0068] In addition, the buckling groove ensures the convenient installation of decorative parts and decorative buckles. In order to enhance the folding performance of the watch strap, a reinforcement piece is introduced on the installation part. On the one hand, its reinforcement arms are arranged in the groove walls on both sides of the buckling groove and tightly fit with the groove walls to provide additional support for the end of the strap, effectively strengthening the structure on both sides of the buckling groove, significantly improving the structural strength of the strap, and avoiding deformation of the strap when subjected to force or bending; on the other hand, the square reinforcement plate located between the two reinforcement arms is embedded in the V-shaped clamping part of the decorative buckle to prevent the decorative buckle from loosening and shifting. Therefore, the design of the reinforcement piece not only optimizes the installation process of the decorative parts, but also effectively improves the overall folding performance of the strap, ensuring that it maintains good structural stability during long-term use and adapts to more high-intensity usage scenarios.

[0069] In order to further improve the strength of the watch strap and the decorative part 2, a hard reinforcing part 4 for strengthening the structure of the watch strap body 1 is also embedded on the mounting portion 11; specifically, the reinforcing part 4 can be made of a hard plastic material; a reinforcing hole 41 corresponding to the limiting hole 14 is provided on the reinforcing part 4, and the limiting protrusion 231 of the limiting part 23 at the bottom of the second tip 23 of the decorative part 2 is simultaneously passed through the limiting hole 14 and the reinforcing hole 41 and fixed.

[0070] Specifically, the reinforcing member 4 includes a reinforcing plate 42 and inclined reinforcing arms 43 connected to either side of the reinforcing plate 42. The reinforcing hole 41 extends through the reinforcing plate 42. The W-shaped snap-fitting slot 15 has mounting slots 16 on both sides thereof for accommodating the reinforcing arms 43. Furthermore, the reinforcing plate 42 is a square-shaped reinforcing plate 42. The inner recess of the clamping portion 31 of the decorative buckle 3 is recessed with retaining slots 33 for accommodating the reinforcing plate 42. The reinforcing plate 42 is inserted into and secured in the retaining slots 33. In this embodiment, to further enhance the stability of the spring tab, the reinforcing arms on either side of the reinforcing member are provided with through-holes (not shown in the accompanying drawings) corresponding to the spring tab mounting holes. The spring tab can pass through both the spring tab mounting hole and the through-hole simultaneously.

[0071] The present invention adds a W-shaped through groove at the opening of the V-shaped mounting portion, and cleverly cooperates with the reinforcement part 4 and the limit part 23 to further improve the folding performance of the watch strap; the design of the V-shaped mounting portion 11 optimizes the force structure of the watch strap, so that the watch strap can more evenly disperse stress under the action of external force and reduce local deformation. The reinforcement part 4 strengthens the rigidity and toughness of the watch strap body 1, providing a more stable installation effect for the decorative part 2, so that the overall stability and comfort of the watch strap and the decorative part 2 are enhanced under long-term wear and high-intensity use environments.

[0072] The present invention also provides a method for disassembling and assembling a decorative piece of a watchband having a detachable decorative piece as described above, wherein the installation of the decorative piece comprises the following steps:

[0073] S1: Insert the decorative piece into the mounting portion with the preset reinforcement piece along the extension direction of the watchband body, so that the limiting piece at the first limiting end is inserted into the limiting groove; in this step, the reinforcing piece is pre-embedded on the mounting portion by the process of existing technology; wherein, during the insertion process of the decorative piece, at least a part of the limiting piece arranged at the bottom of the first limiting end is laterally inserted into the limiting groove opened at the end of the mounting portion, and the limiting groove matches the size and shape of the limiting piece, thereby realizing the lateral limiting cooperation of the decorative piece, ensuring that the decorative piece will not warp or slide off during use, and improving the stability of the decorative structure.

[0074] S2: Press down the decorative part, so that the limiting protrusion of the limiting part at the bottom of the first limiting end is inserted into the limiting hole of the mounting part, and the limiting protrusion of the limiting part at the bottom of the second limiting end is inserted into the reinforcement hole and the mounting hole. In this step, it should be noted that the ratio setting of the limiting protrusion and the limiting part body can ensure that the embedded structures of the two can cooperate smoothly without interference.

[0075] S3: Insert the decorative buckle into the buckle slot along the direction of the watchband's extension, ensuring that the V-shaped clamping portion grips the second stopper. Then, install the spring tab into the decorative buckle, inserting its ends into the spring tab mounting holes on the side walls of the buckle slot, completing the installation of the decorative piece. In this step, push the decorative buckle into the W-shaped buckle slot at the opening of the mounting portion along the direction of the watchband's extension, ensuring that the V-shaped clamping portion of the decorative buckle grips and covers the second stopper of the decorative piece. Then, install the spring tab into the decorative buckle, inserting its ends into the spring tab mounting holes on the side walls of the buckle slot, and finally into the trunnion mounting holes on both sides of the watch case.

[0076] In this step, the process of installing the spring ear is as follows: one end of the spring ear and the reinforcement sleeve as a whole is inserted into the decorative buckle through the adjustment hole, and the position of the spring ear is adjusted by moving the limiting post in the adjustment hole so that the end of the spring ear does not interfere with the groove walls on both sides of the buckling groove. When the end of the spring ear is aligned with the spring ear assembly holes in the groove walls on both sides of the buckling groove, the position of the limiting post is adjusted to allow the spring ear to pass through the spring ear assembly hole.

[0077] Furthermore, the disassembly of the decorative element includes the following steps:

[0078] S1: respectively withdraw the two ends of the spring ears from the spring ear assembly holes on the groove walls on both sides of the buckling groove, and remove the decorative buckle from the mounting portion in a direction away from the decorative component; in this step, a special tool or manual operation can be used to respectively withdraw the spring ears at both ends of the decorative buckle from the spring ear assembly holes on the groove walls on both sides of the buckling groove of the watchband body.

[0079] S2: Sequentially withdraw the limiting protrusions of the limiting piece at the bottom of the second limiting end from the corresponding limiting holes and reinforcement holes; withdraw the limiting protrusions of the limiting piece at the bottom of the first limiting end from the corresponding limiting holes, and then pull the decorative piece out toward the opening direction of the mounting portion, so that the first limiting end is completely withdrawn from the limiting groove.

[0080] In this step, after removing the decorative buckle, continue to pull the decorative part body upward so that the limiting protrusion of the bottom limiting part of the second limiting end withdraws from the reinforcement hole on the reinforcement part and the mounting hole in the mounting part in turn, releasing the downward lock; then continue to pull so that the limiting protrusion of the bottom limiting part of the first limiting end disengages from the limiting hole of the mounting part; finally, pull the decorative part as a whole toward the opening direction of the mounting part so that its first limiting end completely withdraws from the limiting groove of the mounting part, completing the disassembly process.

[0081] The decorative piece installation method of the present invention is easy to operate, and three-way positioning is achieved by using the lateral insertion of the limiting piece, the vertical downward pressure of the decorative piece, and the lateral locking of the decorative buckle: first, the first limiting end of the decorative piece is laterally inserted into the limiting groove preset in the watchband mounting portion through the limiting piece provided at its bottom, thereby achieving preliminary guiding and anti-warping functions; then, the decorative piece is pressed downward so that the limiting protrusion of the first limiting end is inserted into the limiting hole, and at the same time, the limiting protrusion of the limiting piece at the bottom of the second limiting end is simultaneously inserted into the reinforcing hole and the mounting hole on the reinforcing piece, thereby achieving longitudinal compression and structural locking; finally, the decorative buckle together with the spring ear is horizontally pushed into the W-shaped buckling groove so that the V-shaped clamping part and the second limiting end are reliably matched, and at the same time, the spring ear is passed through the assembly holes on the two side walls of the watchband body and connected to the watch case, thereby completing the overall installation; the overall assembly of the decorative piece of the present invention not only ensures structural stability but also reduces the difficulty of operation, and can quickly and accurately complete positioning and fixing without the need for auxiliary tools;

[0082] Similarly, the three-way positioning structure is also executed in reverse order during the disassembly of the decorative parts. The operator first withdraws the spring ear from the spring ear assembly hole, then pulls out the decorative buckle to loosen the clamping structure of the V-shaped clamping part; then, by pulling out the limiting protrusion of the limiting part, withdraw the second limiting end and the first limiting end from the reinforcement hole and the limiting hole in turn, and finally pulls out the decorative part as a whole along the opening direction of the installation part; the entire disassembly and assembly process is simple to operate and the mechanical path is reasonable, which greatly reduces the structural loss and appearance damage that may be caused by repeated disassembly and assembly or user misoperation.

[0083] It should be noted that the present invention also includes other components that can function as a watch strap, such as connecting fasteners, etc. The present invention does not elaborate on their structures, and reference can be made to the watch straps of the prior art.

For ordinary technicians in this field, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
