[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] like Figures 1-4 The diagram shows a watch buckle with a fine-adjustment function provided in this embodiment of the invention. This buckle is used to connect non-metallic watch straps, such as leather straps, plastic straps (including silicone straps), etc. The watch buckle with a fine-adjustment function in this embodiment includes a faceplate 10, an upper release plate assembly 20, a lower release plate 30, a telescopic adjustment member 40, and an adjustment component 50. The buckle connects two watch straps via the faceplate 10 and the telescopic adjustment member 40. The first end of the lower release plate 30 is hinged to the tail end of the upper release plate assembly 20, and the faceplate 10 is hinged to the first end of the upper release plate assembly 20. That is, the faceplate 10 and the lower release plate 30 are respectively hinged to both ends of the upper release plate assembly 20. The lower release plate 30 rotates relative to the upper release plate assembly 20, causing the ring connecting the two watch straps, the watch head, and the buckle to become larger or smaller, thus facilitating the wearing of the watch. The faceplate 10 fixes the watch strap by rotating relative to the upper release plate assembly 20. The connection structure between the aforementioned cover 10, upper disassembly plate assembly 20 and lower disassembly plate 30 can all adopt conventional structures in the art, and will not be described in detail here.

[0026] The lower release plate 30 can be made of hard metal materials such as stainless steel. The lower release plate 30 is strip-shaped and conforms to the shape of the surface of the human wrist. The lower release plate 30 has a receiving cavity and a first clearance notch 32. The first clearance notch 32 is located on the end face of the tail end of the lower release plate 30. The receiving cavity is located inside the first clearance notch 32 and communicates with the first clearance notch 32. That is, the receiving cavity and the first clearance notch 32 are set at the tail end of the lower release plate 30 (the end away from the upper release plate assembly 20) along the length of the watch strap.

[0027] The telescopic adjustment member 40 can also be made of hard metal materials such as stainless steel. It is also strip-shaped, and its dimension along the length of the watch strap is much smaller than that of the lower disassembly plate 30 along the length of the watch strap. The telescopic adjustment member 40 includes a slider portion 41, the width of which (i.e., the dimension of the slider portion 41 along the width of the watch strap) is adapted to the width of the receiving cavity (i.e., the dimension of the receiving cavity along the width of the watch strap). The slider portion 41 has multiple slots 412 arranged along the length of the watch strap, and the distance between adjacent slots 412 is smaller than the distance between adjacent buckles on the watch strap. The telescopic adjustment member 40 is slidably mounted on the tail of the lower disassembly plate 30 such that the slider portion 41 passes through the first clearance notch 32 and at least part of the slots 412 are located in the receiving cavity. That is, after the telescopic adjustment member 40 is installed on the lower disassembly plate 30, the slider portion 41 can slide within the receiving cavity along the length of the watch strap, thereby causing the watch strap mounted on the telescopic adjustment member 40 to slide along the length of the watch strap as well.

[0028] The adjustment component 50 includes a retaining tooth 512, and is slidably mounted to the tail of the lower disassembly plate 30 with the retaining tooth 512 located in the receiving cavity. The wearing length of the watch strap is adjusted by the retaining tooth 512 engaging with different slots 412 on the slider portion 41 of the telescopic adjustment member 40. That is, after the adjustment component 50 is mounted to the lower disassembly plate 30, it can slide relative to the lower disassembly plate 30, so that the retaining tooth 512 also slides synchronously, switching between engaging and disengaging from the slots 412. When the retaining tooth 512 engages with one of the slots 412 of the slider portion 41, the telescopic adjustment member 40 cannot slide, while when the retaining tooth 512 disengages from all slots 412, the telescopic adjustment member 40 can slide relative to the lower disassembly plate 30.

[0029] The aforementioned watch clasp with fine-tuning function, by providing a receiving cavity at the tail end of the lower disassembly plate 30 and sliding the telescopic adjustment member 40 to the tail end of the lower disassembly plate 30, allows for adjustment of the watch's wearing length without removing the watch. This is achieved by sliding the slider portion 41 of the telescopic adjustment member 40 within the receiving cavity, greatly facilitating the adjustment of the watch's wearing length. Furthermore, since the spacing of the slots 412 is smaller than the spacing of the buckle holes on the watch strap, it is convenient to fine-tune the watch's wearing length.

[0030] In one embodiment of this utility model, on the aforementioned telescopic adjustment member 40, the slot 412 is located on one side of the slider portion 41 in the width direction (i.e., the width direction of the watch strap). Correspondingly, the adjustment assembly 50 includes an adjustment button 51 and an elastic member 52, wherein the locking tooth 512 is located on the adjustment button 51, and the adjustment button 51 also includes a pressing portion 511; the tail end of the lower disassembly plate 30 has a second clearance notch 34, which is located on one side of the lower disassembly plate 30 in the width direction (i.e., the width direction of the watch strap), and the second clearance notch 34 communicates with the receiving cavity and is adapted to the size (including shape) of the pressing portion 511. When the adjustment assembly 50 is slidably installed to the tail end of the lower disassembly plate 30, the pressing portion 511 of the adjustment button 51 protrudes from the second clearance notch 34, the elastic member 51 is located in the receiving cavity and pushes the adjustment button 51 so that the locking tooth 512 is embedded in the slot 412 of the slider portion 41 along the width direction of the watch strap. The adjustment button 51 is mounted on the lower plate 30 in a manner that allows it to slide along the width of the watch strap. When the adjustment button 51 is not subjected to external force, the elastic element 52 (e.g., a compression spring) pushes the adjustment button 51, causing the retaining tooth 512 to engage with one of the retaining slots 412 of the slider portion 41. Figure 6 , Figure 7 As shown, by pushing the pressing part 511 of the adjustment button 51 (that is, the part of the adjustment button 51 exposed in the second clearance notch 34), the adjustment button 51 can cause the locking tooth 512 to disengage from the slot 412. At this time, the telescopic adjustment member 40 can be pushed to slide along the length of the watch strap to realize the adjustment of the wearing length of the watch. After the adjustment is in place, the pressing part 511 can be released. The elastic member 52 pushes the adjustment button 51 to make the locking tooth 512 engage in another slot 412 of the slider part 41, thereby keeping the wearing length of the watch stable.

[0031] Of course, in practical applications, the adjustment component 50 can also be set in other parts, but it is difficult to balance the ease of operation with the overall size of the buckle.

[0032] In one embodiment of this utility model, in the telescopic adjustment member 40, the slot 412 is located at the intersection of the side and lower surface of the slider portion 41. The adjustment button 51 includes a connecting rod portion 513, the dimension of the connecting rod portion 513 in the width direction of the watch strap is adapted to the dimension of the slider portion 41 in the width direction of the watch strap, the pressing portion 511 and the locking tooth 512 are respectively located at both ends of the connecting rod portion 513, and the locking tooth 512 protrudes from the upper surface of the connecting rod portion 513. The lower surface of the slider portion 41 of the telescopic adjustment member 40 has a first through groove, which penetrates the lower surface of the slider portion 41 along the width direction of the watch strap. When the telescopic adjustment member 40 and the adjustment assembly 50 are respectively assembled to the tail end of the lower disassembly plate 30, the slot 412 faces away from the second clearance notch 34, the connecting rod portion 513 is embedded in the first through groove on the lower surface of the slider portion 41, and the elastic member 52 is located between the side of the slider portion 41 facing away from the slot 412 and the side wall of the receiving cavity. Specifically, a groove 35 may be provided on the side wall opposite to the receiving cavity and the second clearance notch 34. When the adjusting button 51 is pushed by the pressing part 511 to disengage the locking tooth 512 from the locking slot 412, the locking tooth 512 is inserted into the groove 35. In this way, the structure of the telescopic adjusting member 40 and the adjusting assembly 50 can be made more compact.

[0033] In one embodiment of this utility model, the end of the telescopic adjustment member 40 away from the slider portion 41 has a strap connecting portion for connecting a watch strap, and the end of the slider portion 41 away from the strap connecting portion has a first baffle 411, and a second baffle 37 is provided at the first clearance notch 32. For example, the second baffle 37 is located below the first clearance notch 32, and the first baffle 411 and the second baffle 37 cooperate to prevent the slider portion 41 from completely disengaging from the receiving cavity through the first clearance notch 32. With the above structure, the telescopic adjustment member 40 can be prevented from disengaging from the lower disassembly plate 30 when adjusting the wearing length of the watch.

[0034] In one embodiment of this utility model, the upper surface of the tail end of the lower disassembly plate 30 has a receiving groove 31, and a first clearance notch 32 is located on the side wall adjacent to the tail end of the lower disassembly plate 30 on the receiving groove 31. Correspondingly, the watch buckle with fine adjustment function includes a pressure plate 61, which is fixed to the upper surface of the tail end of the lower disassembly plate 30 and covers the receiving groove 31, thereby forming a receiving cavity. Of course, the above-mentioned receiving cavity can also be directly formed on the lower disassembly plate 30, but the processing difficulty is relatively large.

[0035] Specifically, the sidewall of the receiving groove 31 adjacent to the tail end of the lower disassembly plate 30 has a second through groove 33 arranged along the width direction of the watch strap. For example, the second through groove 33 may be located on both sides of the first clearance notch 32, and the opening of the second through groove 33 faces away from the end face of the tail end of the lower disassembly plate 30. Correspondingly, the pressure plate 61 has an insert 611 adapted to the second through groove 33, and the pressure plate 61 is fixed above the receiving groove 31 by inserting the insert 611 into the second through groove 33. With the above structure, the number of screws used to fix the pressure plate 61 to the lower disassembly plate 30 can be reduced.

[0036] Furthermore, the lower surface of the pressure plate 61 may have a sliding guide groove 612 provided along the length direction of the watch strap. Correspondingly, the upper surface of the slider portion 41 has a sliding guide portion adapted to the sliding guide groove 612, and when the slider portion 41 is assembled into the receiving cavity, the sliding guide portion is embedded in the sliding guide groove 612. With the above structure, the sliding of the slider portion 41 along the length direction of the watch strap can be made more stable.

[0037] Combination Figure 1 , Figure 2 and Figure 8 As shown, in one embodiment of this utility model, the upper surface of the lower disassembly plate 30 has a mushroom-shaped head 36, which is located on the side of the receiving cavity facing away from the telescopic adjustment member 40. The upper disassembly plate assembly 20 includes two parallel support arms and a locking member 11 located between the two support arms. The support arms have clearance positions 221. When the lower disassembly plate 30 is rotated to overlap with the upper disassembly plate assembly 20, the main body of the lower disassembly plate 30 is embedded between the two support arms, and a part of the adjustment component 50 (e.g., the pressing part 511 of the adjustment button 51) is embedded in the clearance position 221. The locking member 21 cooperates with the mushroom-shaped head 36 to lock and fix the lower disassembly plate 30 and the upper disassembly plate assembly 20. With the above structure, not only can the overall thickness of the buckle be reduced, but the adjustment component 50 can also be prevented from being accidentally touched when the watch is worn, thus affecting the stability of the watch.

[0038] Specifically, the locking element 21 may include a round hole, a clip located within the round hole, an elastic element for pushing the clip to hold the mushroom-shaped rivet head 36 within the round hole, and a button for pushing the clip to overcome the elastic force of the elastic element and release the mushroom-shaped rivet head 36 within the round hole. In practical applications, the locking element 21 may also adopt a structure conventional in the art, which will not be described in detail here.

[0039] In one embodiment of this utility model, the faceplate 10 has a nail head 11, and the faceplate 10 is connected to the watch strap by inserting the nail head 11 into the buckle hole of the watch strap; the telescopic adjustment member 40 has a double-ended screw 62, and the telescopic adjustment member 40 is connected to the watch strap by the double-ended screw 62. Of course, in practical applications, the faceplate 10 and the telescopic adjustment member 40 can also be connected to the watch strap in other ways, which will not be described in detail here.

[0040] This utility model also provides a watch, including a watch head, two watch straps, and a clasp with a fine-adjustment function as described above.

[0041] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
