[0012] The first telescopic needle assembly and the second telescopic needle assembly are respectively installed in the special-shaped groove, and when the first inclined surface and the second inclined surface are separated, the end of the first telescopic needle assembly away from the first inclined surface and the end of the second telescopic needle assembly away from the second inclined surface respectively pass through the first through hole and are embedded in the blind hole or the second through hole of the side bead of the adjacent bead assembly; when the first inclined surface and the second inclined surface are in contact with each other, the end of the first telescopic needle assembly away from the first inclined surface and the end of the second telescopic needle assembly away from the second inclined surface are respectively retracted into the first through hole.

[0013] As a further improvement of the present invention, the first telescopic needle assembly includes a telescopic switch key and a first rod-shaped body, and the first inclined surface and the shifting rod portion are both located on the telescopic switch key;

[0014] The first rod-shaped body is fixed to the telescopic switch key at an end facing away from the first inclined surface, and when the first telescopic needle assembly is assembled in the special-shaped groove, the end of the first rod-shaped body away from the telescopic switch key is inserted into a first through hole on the middle bead, and the shifting rod portion protrudes from the outer periphery of the first rod-shaped body and is used to push the first inclined surface to rotate along the central axis of the first rod-shaped body.

[0037] like Figure 1-3 FIG2 is a schematic diagram of the structure of a watch strap provided by an embodiment of the present invention. The watch strap can be applied to wearable devices such as watches and can assist in wearing the wearable device on the user's wrist. Specifically, the watch strap in this embodiment includes a plurality of bead assemblies 10 and a plurality of quick-release assemblies 20, and at least some of the bead assemblies 10 are locked with adjacent bead assemblies 10 via the quick-release assemblies 20. The bead assemblies 10 and the quick-release assemblies 20 can both be made of stainless steel or similar metals. Of course, in actual applications, the bead assemblies 10 and the quick-release assemblies 20 can also be made of other rigid materials, which will not be repeated here.

[0038] Each of the above-mentioned bead components 10 includes a first connecting part and a second connecting part, and the first connecting part and the second connecting part are respectively located at the two opposite ends of the bead component 10, that is, the first connecting part and the second connecting part are respectively located at the two ends of the bead component 10 along the length direction of the strap.

[0039] Each of the quick-release assemblies 20 includes a first telescopic pin assembly 21 and a second telescopic pin assembly 22. The first telescopic pin assembly 21 has a first beveled surface 2121 and a lever portion 2122. Correspondingly, the second telescopic pin assembly 22 has a second beveled surface 2221. The first and second telescopic pin assemblies 21 and 22 of each quick-release assembly 20 are coaxially assembled (e.g., with the axis parallel to the width of the watch strap) to the first connecting portion of a bead assembly 10 and are axially movable relative to the first connecting portion. The first beveled surface 2121 on the first telescopic pin assembly 21 and the second beveled surface 2221 on the second telescopic pin assembly 22 face each other.

[0040] The quick release assembly 20 rotates the first telescopic needle assembly 21 by pushing the lever portion 2122, so that the first inclined surface 2121 of the first telescopic needle assembly 21 and the second inclined surface 2221 of the second telescopic needle assembly 22 are aligned or separated. Figure 3 As shown, when the first bevel 2121 and the second bevel 2221 are separated, the end of the first telescopic needle assembly 21 away from the first bevel 2121 and the end of the second telescopic needle assembly 22 away from the second bevel 2221 are respectively embedded in the second connecting parts of the adjacent bead assemblies 10 to lock the two adjacent bead assemblies; when the first bevel 2121 and the second bevel 2221 are fitted together, the end of the first telescopic needle assembly 21 away from the first bevel 2121 and the end of the second telescopic needle assembly 22 away from the second bead 2221 are respectively retracted into the first connecting part to separate the two adjacent bead assemblies 10.

[0041] In this way, by pushing the lever part 2122 to rotate the first telescopic needle assembly 21, the first inclined surface 2121 on the first telescopic needle assembly 21 and the second inclined surface 2221 on the second telescopic needle assembly 22 can be fitted or separated, so that the first telescopic needle assembly 21 and the second telescopic needle assembly 22 move axially and the first connecting part of the bead assembly 10 is separated or locked with the second connecting part of the adjacent bead assembly 10, so that the two adjacent bead assemblies 10 can be disassembled and assembled without tools, thereby realizing the length adjustment of the watch strap to make the length of the watch strap more suitable for the user's wrist size.

[0042] In one embodiment of the present invention, each bead assembly includes a center bead 12 and two side beads 11, wherein the center bead 12 is assembled between two side beads 11 arranged side by side (along the width of the watchband), and the leading end of the center bead 12 protrudes from the leading ends of the two side beads 11 to form a first connecting portion, and the trailing ends of the two side beads 11 respectively protrude from the trailing ends of the center bead 12 to form a second connecting portion. A clearance groove corresponding to the shape and size of the first connecting portion (i.e., the leading end of the center bead 12) is formed between the trailing ends of the two side beads 11, and when two adjacent bead assemblies 10 are locked, the first connecting portion of one bead assembly 10 is embedded in the clearance groove of the other bead assembly 10.

[0043] This method allows for a tight connection between adjacent bead assemblies, improving the consistency of the watchband. Specifically, in each bead assembly 10, the center bead 12 and the side bead 11 can be connected together using spring lugs or pins, and after connection, the center bead 12 and the side bead 11 can rotate relative to each other. Separating the center bead 12 and the side bead 11 in the same bead assembly 10 typically requires a dedicated tool, which improves the structural stability of a single bead assembly 10. In practical applications, bead assemblies 10 can also employ a five-bead configuration, in addition to a three-bead configuration.

[0044] The structure of the present invention is further described below by taking the bead assembly 10 adopting a three-bead structure as an example.

[0045] Combine Figure 4 As shown, in one embodiment of the present invention, a side surface of the middle bead 12 of the bead assembly 10 has a special-shaped groove 122. For example, the special-shaped groove 122 can be arranged along the width direction of the watchband as a whole. The two side walls of the portion of the middle bead 12 protruding from the two side beads (i.e., the first connecting portion) respectively have first through holes 124 respectively arranged along the width direction of the watchband, and each first through hole 124 is connected to the special-shaped groove 122; accordingly, the inner side walls of the portion of the two side beads 11 protruding from the middle bead 12 (i.e., the portion adjacent to the air-avoiding groove) respectively have second through holes 111 arranged along the width direction of the watchband. In actual applications, the second through holes 111 can also be replaced by blind holes. In particular, the two first through holes 124 can be coaxial, and accordingly, the two blind holes or second through holes 111 can also be coaxial, thereby making it easier to assemble adjacent bead assemblies 10.

[0046] The first telescopic needle assembly 21 and the second telescopic needle assembly 22 are respectively installed in the special-shaped groove 122 and can slide axially in the special-shaped groove 122. When the first inclined surface 2121 and the second inclined surface 2221 are separated, the end of the first telescopic needle assembly 21 away from the first inclined surface 2121 and the end of the second telescopic needle assembly 22 away from the second inclined surface 2221 each pass through a first through hole 124 and are embedded in the blind hole or the second through hole 111 of the side bead 11 of the adjacent bead assembly 10. Figure 5 As shown; when the first bevel 2121 and the second bevel 2221 are in contact with each other, the end of the first telescopic needle assembly 21 away from the first bevel 2121 and the end of the second telescopic needle assembly 22 away from the second bevel 2221 are respectively retracted into the first through hole 124 (including being flush with the opening of the first through hole 124), as shown Figure 6 shown.

[0047] The aforementioned special-shaped groove 122 greatly facilitates the assembly of the first and second telescopic pin assemblies 21, 22. Specifically, the special-shaped groove 122 can be located on the lower surface of the center bead 12, which contacts the skin of the wrist when the watchband is worn. This conceals the first and second telescopic pin assemblies 21, 22, and prevents accidental separation of adjacent bead assemblies 10 due to accidental activation of the lever 2122.

[0048] Combine Figure 4 、 Figure 7 As shown, in one embodiment of the present invention, the first telescopic needle assembly 21 includes a telescopic switch key 212 and a first rod-shaped body 211, wherein a first inclined surface 2121 and a lever portion 2122 are both located on the telescopic switch key 212. The first rod-shaped body 211 is fixed to the end of the telescopic switch key 212 facing away from the first inclined surface 2121. When the first telescopic needle assembly 21 is assembled into the special-shaped groove 122, the end of the first rod-shaped body 211 away from the telescopic switch key 212 is inserted into a first through hole 124 on the center bead 12. The lever portion 2122 protrudes from the outer periphery of the first rod-shaped body and is used to push the first inclined surface 2121 to rotate along the central axis of the first rod-shaped body 211, thereby causing the first inclined surface 2121 to be in contact with or separated from the second inclined surface 2221 of the second telescopic needle assembly 22.

[0049] Specifically, the first rod-shaped body 211 can be divided into three sequentially connected and coaxial sections: a first plug-in section 2112, a first sliding section 2111, and a threaded section 2113. The diameters of the first plug-in section 2112 and the threaded section 2113 are each smaller than the diameter of the first sliding section 2111. Accordingly, the telescopic switch key 212 comprises a first columnar body 2120 having the same diameter as the second sliding section 2111. A first inclined surface 2121 is located at one end surface of the first columnar body 2120. A lever portion 2122 is connected to the outer circumference of the first columnar body 2120. A threaded hole 2125 is defined on the end of the first columnar body 2120 facing away from the first inclined surface 2121. The threaded section 2113 of the first rod-shaped body 211 is threadedly engaged with the threaded hole 2125, thereby achieving a fixed connection between the first rod-shaped body 211 and the telescopic switch key 212.

[0050] Combine Figure 5 、 Figure 6As shown, when the first telescopic needle assembly 21 is assembled in the special-shaped groove 122, the first plug-in section 2112 of the first rod-shaped body 211 is inserted into the first through hole 124 of the middle bead 12 and can slide along the first through hole 124; the bottom of the first sliding section 2111 and the first columnar body 2120 of the telescopic switch key 212 are attached to the bottom of the special-shaped groove 122 (the shape and size of the bottom of the first sliding section 2111 can be adapted to the shape and size of the bottom of the special-shaped groove 122), and the special-shaped groove 122 constitutes a slide rail, and the first sliding section 2111 and the first columnar body 2120 constitute a slider, guiding the first telescopic needle assembly 21 to slide axially in the special-shaped groove 122.

[0051] The first telescopic needle assembly 21 is formed by assembling two independent components, namely the telescopic switch key 212 and the first rod-shaped body 211, which can reduce the difficulty of manufacturing the first telescopic needle assembly 21. Of course, in actual applications, the first telescopic needle assembly 21 can also be made of a single integral component.

[0052] Combine Figure 4 、 Figure 8 As shown, in one embodiment of the present invention, the second telescopic needle assembly 22 includes a second rod-shaped body 221 and a positioning member 222, and the second inclined surface 2221 is located on the positioning member 222. The positioning member 222 has a first positioning structure, and correspondingly, the special-shaped groove 122 has a second positioning structure. When the second telescopic needle assembly 22 is assembled in the special-shaped groove 122, the second rod-shaped body 221 passes through the positioning member 222, and the end of the second rod-shaped body 221 facing away from the second inclined surface 2221 is inserted into the other first through hole 124 on the middle ball 12. The second inclined surface 2221 is prevented from rotating by the first positioning structure and the second positioning structure.

[0053] Specifically, the first positioning structure on the above-mentioned positioning member 222 can be a groove 2222 on the surface of the positioning member 222, and the groove 2222 is arranged along the axial direction of the second rod-shaped body 221; the second positioning structure is the ridge at the bottom of the special-shaped groove 122, and when the second telescopic needle assembly 22 is assembled to the special-shaped groove 122, the ridge at the bottom of the special-shaped groove 122 is embedded in the groove 2222 on the surface of the positioning member 222, thereby preventing the positioning member 222 from rotating, and accordingly, the second inclined surface 2221 cannot rotate either.

[0054] Specifically, the second rod-shaped body 221 may include a guide section 2211, a second sliding section 2212, and a second plug section 2213, which are sequentially connected. The diameters of the second plug section 2213 and the guide section 2211 are respectively smaller than the diameter of the second sliding section 2212. Accordingly, the positioning member 222 includes a second columnar body 2220 having the same diameter as the second sliding section 2212. The second inclined surface 2221 is located on one end surface of the second columnar body 2220. The second columnar body 2220 has a central through hole. The guide section 2211 of the second rod-shaped body 221 is inserted into the central through hole of the second columnar body 2220, with the second inclined surface 2221 facing away from the second sliding section 2212.

[0055] Combine Figure 5 、 Figure 6 As shown, when the second telescopic needle assembly 22 is assembled in the special-shaped groove 122, the second plug-in section 2213 of the second rod-shaped body 221 is inserted into the other first through hole 124 of the middle bead 12 and can slide along the first through hole 124; the second sliding section 2212 and the bottom of the second columnar body 2220 of the positioning member 222 are attached to the bottom of the special-shaped groove 122 (the shape and size of the bottom of the second sliding section 2212 can be adapted to the shape and size of the bottom of the special-shaped groove 122), and the special-shaped groove 122 constitutes a slide rail, and the second sliding section 2212 and the second columnar body 2220 constitute a slider, guiding the second telescopic needle assembly 22 to slide axially in the special-shaped groove 122.

[0056] The second telescopic needle assembly 22 is formed by assembling the positioning member 222 and the second rod-shaped body 221 as two independent components, which can reduce the difficulty of manufacturing the second telescopic needle assembly 22. Of course, in actual application, the second telescopic needle assembly 22 can also be made of a single integral component.

[0057] Combine Figure 3 As shown, after the above-mentioned first telescopic needle assembly 21 and the second telescopic needle assembly 22 are assembled into the special-shaped groove 122, the first telescopic needle assembly 21 can be rotated by toggling the toggle lever portion 2122, and the first inclined surface 2121 also rotates accordingly. During this process, the positioning piece 222 of the second telescopic needle assembly 22 does not rotate, and accordingly, the second inclined surface 2221 does not rotate either. Since the first telescopic needle assembly 21 and the second telescopic needle assembly 22 are coaxial, the first inclined surface 2121 and the second inclined surface 2221 can be made to fit together or separate by driving the first inclined surface 2121 to rotate. When the first inclined surface 2121 and the second inclined surface 2221 fit together, the total length of the first telescopic needle assembly 21 and the second telescopic needle assembly 22 is reduced, so that the two ends of the first telescopic needle assembly 21 and the second telescopic needle assembly 22 can be retracted into the first through holes 124 on both sides of the middle bead 12, respectively, as shown in FIG. Figure 6As shown; when the first bevel 2121 and the second bevel 2221 are separated, the total length of the first telescopic needle assembly 21 and the second telescopic needle assembly 22 increases, so that the two ends of the first telescopic needle assembly 21 and the second telescopic needle assembly 22 can be inserted into the blind holes or the second through holes 111 of the side beads on both sides of the middle bead 12, as shown Figure 5 shown.

[0058] In particular, the angle between the first inclined surface 2121 and the central axis of the first rod-shaped body 211, as well as the angle between the second inclined surface 2221 and the central axis of the second rod-shaped body 221, can be 30-60°, which can not only meet the structural strength requirements but also ensure the telescopic length of the first telescopic needle assembly 21 and the second telescopic needle assembly 22.

[0059] To ensure that the end of the second telescopic needle assembly 22 automatically exits the blind hole or the second through hole 111 of the edge bead 11 when the first inclined surface 2121 and the second inclined surface 2221 are in contact with each other, the second telescopic needle assembly 22 may further include an elastic member 223. The elastic member 223 is assembled between the second rod-shaped body 221 and the sidewall of the special-shaped groove 122, and pushes the end of the second rod-shaped body 221 inserted into the first through hole 124 to move away from the first through hole 124. In particular, the elastic member 223 may be a spring, and the spring may be sleeved on the second insertion section 2213 of the second rod-shaped body 221.

[0060] Similarly, the first telescopic needle assembly 21 may also include a spring that can be sleeved on the first insertion section 2112 of the first rod-shaped body 211, thereby pushing the end of the first rod-shaped body 211 inserted into the first through hole 124 to move away from the first through hole 124. In actual application, the end of the first rod-shaped body 211 inserted into the first through hole 124 can also be withdrawn from the blind hole or the second through hole 111 of the side bead 11 by axially pushing the lever portion 2122.

[0061] like Figure 4 As shown, in one embodiment of the present invention, the end of the telescopic switch key 212 where the first inclined surface 2121 is located has an axial hole 2126. When the first and second telescopic needle assemblies 21 and 22 are installed in the special-shaped groove 122, the end of the second rod-shaped body 221 facing the second inclined surface 2221 (i.e., the guide section 2211) is inserted into the axial hole 2126 of the telescopic switch key 212. This structure ensures that the first and second telescopic needle assemblies 21 and 22 remain coaxial, further facilitating the alignment of the first and second inclined surfaces 2121 and 2221.

[0062] In one embodiment of the present invention, one side surface of the center bead 12 has a mounting groove 121 and a receiving groove 123 for accommodating a lever portion 2122. The receiving groove 123 is located to the side of the special-shaped groove 122, and both the special-shaped groove 122 and the receiving groove 123 are located at the bottom of the mounting groove 121. When the first and second telescopic needle assemblies 21 and 22 are assembled into the special-shaped groove 122, the lever portion 2122 can be positioned within the receiving groove 123. Specifically, when the lever portion 2122 is positioned within the receiving groove 123, the first and second telescopic needle assemblies 21 and 22 interlock the first connecting portion of the bead assembly 10 with the second connecting portion of the adjacent bead assembly 10. When the lever portion 2122 is pushed above the special-shaped groove 122, the first and second telescopic needle assemblies 21 and 22 separate the first connecting portion of the bead assembly 10 from the second connecting portion of the adjacent bead assembly 10.

[0063] Correspondingly, the bead assembly 10 further includes a cover plate 14 having a shape and size that matches the assembly groove 121. The cover plate 14 has an operation window 141. When the cover plate 14 is fixed to the assembly groove 121, the portion of the accommodating groove 123 and the special-shaped groove 122 adjacent to the accommodating groove 123 are exposed through the operation window 141. In particular, the cover plate 14 may have a first screw hole 142, and the bottom of the assembly groove 121 may have a second screw hole 126. The cover plate 14 may be fixed to the assembly groove 121 by screws 15 that are threadedly connected to the first screw hole 142 and the second screw hole 126, respectively. When the cover plate 14 is fixed to the assembly groove 121, the upper surface of the cover plate 14 is flush with the surface of the middle bead 12. Furthermore, when the first telescopic needle assembly 21 and the second telescopic needle assembly 22 are assembled in the special-shaped groove 122 and the accommodating groove 123 , the lever portion 2122 is exposed from the operation window 141 , and the lever portion 2122 can be moved to rotate the first telescopic needle assembly 21 .

[0064] The cover plate 14 can realize the first telescopic needle assembly 21 and the second telescopic needle assembly 22 in the special-shaped groove 122 , which not only makes the overall appearance beautiful, but also prevents the first telescopic needle assembly 21 and the second telescopic needle assembly 22 from accidentally falling out of the special-shaped groove 122 .

[0065] In one embodiment of the present invention, a recess 2123 is provided on the side of the above-mentioned lever portion 2122 facing away from the first rod-shaped body 211, so that the lever portion 2122 is in the shape of a duck head. In this way, when the lever portion 2122 rotates to above the special-shaped groove 122, it can avoid the cover plate through the recess 2323, so that the first telescopic needle assembly 21 can move axially as a whole, thereby facilitating the end of the first rod-shaped body 211 to exit from the blind hole or the second through hole 111 of the side bead 11.

[0066] Furthermore, a through slot 2124 may be provided on the lever portion 2122. When the lever portion 2122 is located in the receiving groove 123, the opening of the through slot 2124 faces the bottom wall of the receiving groove 123. The through slot 2124 facilitates the use of a toothpick or fingernail to remove the lever portion 2122 from the receiving groove 123, thereby facilitating the assembly and disassembly of adjacent bead assemblies 10.

[0067] The present invention also provides a watch, which comprises a watch case and the watch strap as described above, and the watch case and the watch strap can be connected together by any existing method.

[0068] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
