[0024] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate typical embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] Figure 1 The diagram shown is a structural schematic of a quick-release watch strap link provided in an embodiment of this utility model. Figure 1As shown, the quick-release watch strap link 2 provided by this utility model includes a center bead module 21 and a first side bead 22 and a second side bead 23 connected to two opposite sides of the center bead module 21. Multiple links are sequentially connected to form a watch strap. The watch strap is fixed to the outer wall of the watch face via lugs 1 to connect the strap to the watch face. The first side bead 22 and the second side bead 23 are arranged facing each other along the width direction of the watch strap and are both offset from the center bead module 21, so that the center bead modules 21 of other links can be movably connected between the first side bead 22 and the second side bead 23.

[0027] Figure 2 The image shown is an exploded view of a quick-release watch strap link according to an embodiment of this utility model. Figure 2 As shown, the middle bead module 21 includes a middle bead base 210, a pushable actuating component 220, a first connecting pin 230, a second connecting pin 240, and a linkage rod 250. The inner part of the center bead base 210 is provided with a groove 2101 for assembling the actuating component 220. The center bead base 210 has a first through hole 2102 and a second through hole distributed on two sides along the width direction of the watch strap for assembling the first connecting pin 230 and the second connecting pin 240. The assembly end of the first connecting pin 230 is directly connected to the actuating component 220, and the assembly end of the second connecting pin 240 is connected to the actuating component 220 through a linkage rod 250. The parts of the first connecting pin 230 and the second connecting pin 240 exposed in the center bead base 210 are connected to the first side bead 22 and the second side bead 23 of the lug 1 or other links. The movement of the first connecting pin 230 and the second connecting pin 240 is controlled by controlling the actuating component 220, thereby realizing the connection and disconnection of the links with the lug 1 or other links. When the watch strap needs to be replaced, push the actuating component forward. The actuating component moves the first connecting pin 4, and at the same time, the linkage rod 250 moves the second connecting pin 5 on the other side in the opposite direction. After the connecting pins on both sides retract inward to a certain distance, they can be disengaged from the connecting hole of the watch case, thus separating the watch strap from the watch case and completing the disassembly.

[0028] In this invention, a groove for assembling the actuating component is formed inside the central bead base, and two through holes are located on both sides for assembling connecting pins. The actuating component controls the movement of the connecting pins, thereby connecting or separating the watch strap from the lugs or other links. By controlling the actuating component, the connecting pin can be retracted in a specific direction, thus disassembling the links. Therefore, users can quickly change the watch strap simply by pushing the actuating component. This is especially suitable for users who need to frequently change watch straps.

[0029] Figure 3 As shown Figure 2 The side view of the toggle assembly shown; Figure 4 As shown Figure 2 The side view of the central bead base is shown. (As shown) Figure 3 and Figure 4 As shown, the actuating assembly 220 includes a toggle block 2201, a drive plate 2202, and a drive protrusion 2203. The drive plate 2202 and the drive protrusion 2203 are disposed on the side of the toggle block 2201 facing the middle ball base 210 and are accommodated in the groove 2101. Further, a limiting groove 22021 is formed on the drive plate 2202, and a limiting plate 2301 that cooperates with the limiting groove 22021 is provided at the assembly end of the first connecting pin 230. When the toggle block 2201 is pushed by an external force, the drive plate 2202 drives the first connecting pin 230 to move, completing the retraction of the first connecting pin 230.

[0030] In this invention, when the toggle block is pushed by an external force, it drives the movement of the entire system. The drive plate is connected to the toggle block and plays a guiding and pushing role when the toggle block is pushed. The drive protrusion cooperates with the middle ball base 210 to ensure the precise execution of the toggle component's action. Thus, when the toggle block 2201 is pushed, the drive plate 2202 moves along with it and cooperates with the groove 2101 of the middle ball base 210 through the drive protrusion 2203. The limiting groove 22021 on the drive plate 2202 cooperates with the limiting plate 2301 of the first connecting pin 230, thereby limiting the movement trajectory of the first connecting pin 230. The pushing of the toggle block causes the drive plate to move, which in turn pushes the first connecting pin 230 to retract inward.

[0031] Figure 5 As shown Figure 2 The side view of the linked component shown. (See attached image.) Figure 2 and Figure 5 As shown, the middle bead module 21 also includes a linkage component 260. The linkage component 260 includes a first U-shaped groove 2601 connected to the drive protrusion 2203, a second U-shaped groove 2502 connected to the linkage rod 250, and a positioning hole 2503 connected to the positioning protrusion 2103 of the middle bead base 210. The assembly end of the second connecting pin 240 has a connecting through hole 2401 for accommodating the linkage rod 250. The above constitutes the inward retraction of the second connecting pin 5. Figure 6 As shown, when the lever 2201 is pushed by an external force, it drives one end of the linkage component 260 to move, and the other end of the linkage component 260 drives the second connecting pin 240 to move in the opposite direction, thus completing the retraction of the second connecting pin 5.

[0032] In this invention, the first U-shaped groove 2601 is connected to the driving protrusion 2203, responsible for transmitting the movement of the actuating component. The second U-shaped groove 2502 is connected to the linkage rod 250, transmitting power through this component. The positioning hole 2503 connects to the positioning protrusion 2103 of the middle ball base 210, used to ensure the position of the linkage component. The pushing of the toggle block 2201 not only drives the actuating component 220, but also transmits force through the linkage component 260. This design causes the other end of the linkage component to drive the second connecting pin 240 to move in the opposite direction, thereby completing the retraction process of the second connecting pin 240.

[0033] This invention, through the coordinated operation of the actuating component 220 and the linkage component 260, ensures that both the first connecting pin 230 and the second connecting pin 240 can retract smoothly and efficiently, thereby enabling the disassembly and replacement of the watch strap. The pushing of the actuating block, the cooperation between the drive plate and the drive protrusion, and the design of the limiting groove and the limiting plate ensure the precision of the movement. The linkage component further ensures the synchronization and stability of the entire process.

[0034] Furthermore, in one embodiment of this utility model, as Figure 2As shown, the ball bearing module 21 also includes a first return spring 270 and a second return spring 280. The main function of the first return spring 270 and the second return spring 280 is to ensure that the actuation assembly and the connecting pin can automatically return to their initial positions after the external force is removed, thereby achieving a stable connection between the watch strap and the watch case. The first return spring 270 is connected between the assembly end of the first connecting pin 230 and the assembly end of the second connecting pin 240. When the actuation block 2201 is pushed by an external force, the first connecting pin 230 and the second connecting pin 240 will retract inward, and the first return spring 270 will be compressed. When the external force is removed, the first return spring 270 drives the first connecting pin 230 and the second connecting pin 240 to reset through deformation force. The two ends of the second return spring 280 are in contact with the inner sidewall of the groove 2101 of the drive plate 2202 and the ball bearing base 210, respectively. When the actuation block 2201 is pushed, the drive plate 2202 will compress the second return spring 280, causing the actuation assembly 220 to retract inward. After the external force is removed, the restoring force of the second return spring 280 drives the drive plate 2202 to reset, ensuring that the actuating assembly and connecting pin can return to their initial state. In this embodiment, when the toggle block 2201 is pushed by an external force, the drive plate 2202 compresses the second return spring 280, causing the first connecting pin 230 and the second connecting pin 240 to retract inward. At the same time, the first return spring 270 is compressed, and the connecting pin moves inward, preparing for the strap link to enter the watch case or other strap link assembly positions. Once the external force is removed, the first return spring 270 and the second return spring 280 will drive the actuating assembly 220, the first connecting pin 230, and the second connecting pin 240 to return to their initial positions through deformation force. After the connecting pins are reset, they will automatically extend into the connecting holes of the watch case or other strap links, thereby completing the installation of the watch strap.

[0035] Therefore, when connecting the watch strap using this utility model to the watch case, simply push the actuating component to retract the connecting pins on both sides inward. After the strap link enters the corresponding assembly position of the watch case or other strap links, release the actuating component. The actuating component and the connecting pins on both sides will return to their initial positions under the action of the spring, and the connecting pins will extend into the connecting holes of the watch case or other strap links to complete the connection.

[0036] The spring system design ensures that the actuating component and connecting pin reliably and automatically reset during use. By pushing the actuating component to retract the connecting pin, and then relying on the spring to return it to its initial state upon release, the operation of connecting the strap to the case is greatly simplified. The spring design ensures that the connecting pin can be securely inserted into the connecting hole of the case or strap link, providing a safe and stable connection.

[0037] Furthermore, in one embodiment of this utility model, as Figure 2 and Figure 4As shown, the ball bearing module 21 further includes a third connecting pin 290 and a fourth connecting pin 300. The ball bearing base 210 has a third through hole 2104 and a fourth through hole for assembling the third connecting pin 290, and a fifth through hole 2105 and a sixth through hole for assembling the fourth connecting pin 300, distributed along two sides in the width direction of the watch strap. The position and number of these through holes ensure that the connecting pins can pass through smoothly and ensure a secure assembly. The drive plate 2202 has a limiting hole 22022 for connecting the fourth connecting pin 300. The design of the limiting hole ensures that the fourth connecting pin can be stably positioned on the actuating component, preventing displacement or detachment between the actuating component and the ball bearing base. Both ends of the third connecting pin 290 and the fourth connecting pin 300 are knurled to enhance the friction between the connecting pin and the ball bearing base, preventing loosening or detachment during use. A limiting hole is provided on the drive plate of the actuation component. The third connecting pin and the fourth connecting pin pass through the through hole on the middle ball base and the limiting hole on the actuation component, connecting the middle ball base and the actuation component to ensure that the actuation component will not fall off after assembly.

[0038] In this embodiment, the third and fourth connecting pins pass through the through hole and mate with the limiting hole, making the assembly process simpler and more efficient. The third and fourth connecting pins ensure that the actuating component and the middle ball base are reliably fixed after assembly and prevent them from falling off. The limiting hole, in conjunction with the connecting pins, firmly secures the actuating component to the middle ball base. Simultaneously, the knurled design of the connecting pins increases the contact area with the through hole, further enhancing the stability of the fixation.

[0039] Similarly, the links provided by this utility model can also be used to connect watch strap links, allowing for convenient and quick adjustment of the watch strap length by removing or adding links to accommodate different wrist sizes.

[0040] Compared to existing technologies, the link structure provided by this invention allows users to quickly install and remove watch straps without any professional skills or additional tools. This greatly simplifies the operation process for consumers, making strap replacement faster and more convenient. Traditional watch strap replacement usually requires special tools, such as strap removal tools. This invention eliminates this need; consumers can replace the strap manually, making it convenient and quick. With the increasing market demand for quick strap replacement, this design meets consumers' needs for rapid strap length adjustment or replacement, thereby enhancing the product's market competitiveness.
