Technical Field

[0001] This utility model relates to the field of watches, and more specifically, to a quick-release watch strap and a watch. Background Technology

[0002] A wristwatch, also known as a watch face, is an instrument worn on the wrist for telling and displaying time. A wristwatch generally consists of a watch face (used to display the time) and a watch strap. The watch strap is usually made of materials such as leather, rubber, nylon, and metal (such as stainless steel), and is used to fasten the watch face to the wrist.

[0003] Currently, to facilitate strap length adjustment, most metal watch straps on the market use a quick-release mechanism, meaning that the strap beads can be removed without tools to adjust the strap length by adding or removing beads. However, existing quick-release straps have a relatively complex structure, and the disassembly and assembly process is also relatively cumbersome. Utility Model Content

[0011] As a further improvement of this utility model, the head end of the locking pin has a plurality of circumferentially distributed axial teeth, and the head end of the locking pin is locked and fixed in the third ear hole of the first side bead by the axial teeth.

[0012] As a further improvement of this utility model, the tail end of the locking pin has a circumferential groove, the lower surface of the rear end of the second side bead has a bottom hole, and the bottom hole extends from the lower surface of the second side bead to the fourth ear hole; the locking assembly includes a locking pin, and after the circumferential groove at the tail end of the locking pin is inserted into the fourth ear hole, the locking pin is inserted into the bottom hole and embedded in the circumferential groove to lock the tail end of the locking pin in the fourth ear hole of the second side bead.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] This invention relates to a quick-release watch strap that can be applied to metal (e.g., stainless steel) watch straps. It can be fixed to the watch head, allowing the watch to be worn. Figure 1 The diagram shown is a structural schematic of the quick-release watch strap provided in this embodiment of the invention. The quick-release watch strap includes multiple bead assemblies, which have the same shape and structure and are connected sequentially along the length of the strap. In this quick-release watch strap, the bead assemblies can be installed and removed without the need for tools, thus allowing for convenient and simple adjustment of the strap length.

[0030] In this embodiment of the quick-release watchband, each bead assembly includes a first side bead 10, a second side bead 20, a center bead assembly 30, a locking assembly, and a quick-release connecting assembly 40. The front end of the center bead assembly 30 is fitted between the first side bead 10 and the second side bead 20 via the locking assembly. The rear end of the center bead assembly 30 protrudes beyond the rear ends of the first side bead 10 and the second side bead 20. A groove is formed between the front ends of the first side bead 10 and the second side bead 20 for adjacent bead assemblies (i.e., the rear ends of the center bead assemblies in adjacent bead assemblies) to be inserted. The shape and size of the groove can be adapted to the portion of the center bead assembly 30 that protrudes beyond the rear ends of the first side bead 10 and the second side bead 20. The first side bead 10, the second side bead 20, and the center bead assembly 30 are all made of stainless steel or other metal materials. The center bead 30 can be a single component or a combination of multiple components. The shapes of the first side bead 10, the second side bead 20, and the center bead assembly 30 can adopt common shapes in the art, which will not be described in detail here.

[0031] The front end of the inner surface of the first side bead 10 has a first ear hole 11, and the front end of the inner surface of the second side bead 20 has a second ear hole 21, as shown above. Figure 2 As shown, the central bead assembly 30 includes a first through hole 36 located at the front end and a second through hole 37 located at the rear end. The first through hole 36 and the second through hole 37 respectively penetrate the central bead assembly 30 along the width direction of the watch strap, and the first ear hole 11, the second ear hole 21 and the first through hole 36 are coaxial. The first ear hole 11 and the second ear hole 21 can be blind holes respectively.

[0032] Combination Figures 3-4 As shown, the quick-release connector assembly 40 includes a disassembly tube 41, a telescopic pin 42, and an elastic element 43. The disassembly tube 41 is cylindrical in shape and includes an axial hole 412 and a first nail head 411. The first nail head 411 is located at the first end of the disassembly tube 41, and the opening of the axial hole 412 is located at the tail end of the disassembly tube 41. The shape and size (including radial and axial dimensions) of the first nail head 411 are adapted to the shape and size of the first ear hole 11 on the first side bead 10, and the radial dimension of the first nail head 411 is smaller than the radial dimension of the main body of the disassembly tube 41. The tail end of the telescopic pin 42 has a second nail head 421 and a clamping section 424 located inside the second nail head 421. The shape and size (including radial and axial dimensions) of the second nail head 421 are adapted to the shape and size of the second ear hole 21 on the second side bead 20. The elastic element 43 and the telescopic pin 42 are installed in the axial hole 412 of the disassembly tube 41, and the second pin head 421 of the telescopic pin 42 extends out of the tail end of the disassembly tube 41 under the push of the elastic element 43, so that the entire quick-release connection assembly 40 can be pulled out by directly gripping the clamping section 424, thereby separating the adjacent beaded assemblies. In particular, the clamping section 424 may include a groove for easy clamping.

[0033] The quick-release connecting assembly 40 connects two adjacent beaded components by inserting the first nail head 411 into the first ear hole 11 of the first side bead 10, the main body of the disassembly tube 41 passing through the first through hole 36 of the middle bead assembly 30 and the second through hole 37 of the middle bead assembly 30 of the adjacent beaded component in the groove, and inserting the second nail head 421 into the second ear hole 21 of the second side bead 20. That is, the adjacent beaded components are connected end to end by the quick-release connecting assembly 40 and can rotate relative to each other.

[0034] Furthermore, the free end of the second nail head 421 has a sliding guide surface. When the second side bead 20 rotates around the locking assembly (e.g., by external force pushing the second side bead 20 to rotate), the sliding guide surface pushes the free end of the second nail head 421 to move backward and retract into the axial hole 412 of the dismantling tube 41 (while simultaneously pushing the elastic member 43 into a compressed state). When the elastic member 43 pushes the clamping section 424 of the telescopic needle 42 to extend out of the axial hole 412 when the second side bead 20 leaves the tail end of the axial hole 412 of the dismantling tube 41 (i.e., the inner side wall of the second side bead 20 leaves the axial projection of the axial hole 412), it can be understood that in order for the free end of the second nail head 421 to move backward smoothly when the second side bead 20 rotates, when the second side bead 20 is not rotating, the second nail head 421 abuts against the side wall of the opening of the second ear hole 21 (i.e., the inner side wall of the second side bead 20) through the sliding guide surface.

[0035] The aforementioned quick-release watchband, by providing a sliding guide surface at the free end of the second pin of the telescopic pin, allows the free end of the second pin to retract into the axial hole of the disassembly tube when the second side bead rotates around the locking assembly. Furthermore, when the second side bead leaves the first through hole, the elastic element pushes the clamping section of the telescopic pin to extend out of the axial hole of the disassembly tube. This simplifies the connection structure between the bead assemblies and facilitates the disassembly of adjacent bead assemblies.

[0036] like Figure 2 As shown, in one embodiment of the present invention, the lower surface of the second side bead 20 has a groove 23, which extends from the lower surface of the second side bead 20 to the inner surface of the second side bead 20 (i.e. the surface facing the middle bead assembly 30), and the bottom wall of the groove 23 extends to the opening of the second ear hole 21. Thus, when assembling two adjacent beaded assemblies together, the second side bead 20 can be rotated to expose the first through hole 36 of the middle bead assembly 30 (or the second through hole of the middle bead assembly in the adjacent beaded assemblies in the groove). Then, the head end of the quick-release connecting assembly 40 is inserted into the first through hole 36 of the middle bead assembly 30 and the second through hole of the middle bead assembly in the adjacent beaded assemblies in the groove, until the first nail head 411 is inserted into the first ear hole 11 of the first side bead 10. Then, the second side bead 20 is rotated, and the bottom wall of the inclined groove 23 pushes the second nail head 421 to move backward and retract into the axial hole 412 of the disassembly tube 41, until the second ear hole 21 is aligned with the axial hole 412. The second nail head 421 is inserted into the second ear hole 21 under the push of the elastic element, and the assembly is completed.

[0037] like Figure 2 As shown, in one embodiment of the present invention, the inner surface of the rear end of the first side bead 10 has a third ear hole, the inner surface of the rear end of the second side bead 20 has a fourth ear hole 22, and the middle part of the middle bead assembly 30 includes a third through hole, which penetrates the middle bead assembly 30 along the width direction of the watch strap; correspondingly, the locking assembly includes a locking pin 51, which passes through the third through hole and the two ends of the locking pin 51 are respectively inserted into the third ear hole of the first side bead 10 and the fourth ear hole 22 of the second side bead 20, thereby connecting the first side bead 10, the middle bead assembly 30 and the second side bead 20 together.

[0038] Specifically, the head end of the aforementioned locking pin 51 has multiple circumferentially distributed axial teeth 511, and the head end of the locking pin 51 is locked and fixed in the third ear hole of the first side bead 10 through the axial teeth 511. For example, the locking pin 51 can be tightly fitted with the third ear hole through the axial teeth 511. Of course, in practical applications, other methods can also be used to fix the locking pin 51 and the first side bead 10.

[0039] In one embodiment of this utility model, the tail end of the locking pin 51 has a circumferential groove 512. Correspondingly, the lower surface of the rear end of the second side bead 20 has a bottom hole 24, and the bottom hole 24 extends from the lower surface of the second side bead 20 to the fourth ear hole 22. The locking assembly also includes a locking pin 52. After the circumferential groove 512 at the tail end of the locking pin 51 is inserted into the fourth ear hole 22, the locking pin 52 is inserted into the bottom hole 24 and embedded in the circumferential groove 512 to lock the tail end of the locking pin 51 into the fourth ear hole 22 of the second side bead 20. Figure 5 As shown. This structure facilitates the disassembly and assembly of the first side bead 10, the second side bead 20, and the middle bead assembly 30.

[0040] like Figure 2 As shown, in one embodiment of this utility model, the aforementioned middle bead assembly 30 includes two rows of middle beads 31, three rows of middle beads 32, four rows of middle beads 33, five rows of middle beads 34, and six rows of middle beads 35. The two rows of middle beads 31, three rows of middle beads 32, four rows of middle beads 33, five rows of middle beads 34, and six rows of middle beads 35 each include a front through hole 38 and a rear through hole 39 arranged along the width direction of the watch strap. The locking pin 51 passes sequentially through the front through hole of the two rows of middle beads 31, the rear through hole of the three rows of middle beads 32, the front through hole of the four rows of middle beads 33, the rear through hole of the five rows of middle beads 34, and the front through hole of the six rows of middle beads 35 to secure the two rows of middle beads 31. The three-row middle beads 32, four-row middle beads 33, five-row middle beads 34, and six-row middle beads 35 are assembled between the first side bead 10 and the second side bead 20. That is, the front through holes 38 of the three-row middle beads 32 and the five-row middle beads 34 together form the first through hole 36 of the middle bead assembly 30, the rear through holes 39 of the two-row middle beads 31, the four-row middle beads 33, and the six-row middle beads 35 together form the second through hole 37 of the middle bead assembly 30, and the front through holes of the two-row middle beads 31, the rear through holes of the three-row middle beads 32, the front through holes of the four-row middle beads 33, the rear through holes of the five-row middle beads 34, and the front through holes of the six-row middle beads 35 together form the third through hole.

[0041] In practical applications, the middle bead assembly 30 may also include three middle beads, seven middle beads, etc., and its connection structure is similar to the structure described above, so it will not be described again here.

[0042] In one embodiment of the present invention, the telescopic pin 42 includes a locking section 422 located inside the clamping section 424, and the diameter of the locking section 422 is larger than the diameter of other parts of the telescopic pin 42 (e.g., the second nail head 421 and the clamping section 424). Correspondingly, the diameter of the opening of the axial hole 412 is smaller than the diameter of the locking section 422 and larger than the diameter of the second nail head 421 and the clamping section 424. The diameter of the opening of the axial hole 412 is smaller than the diameter of the part inside the opening. The telescopic pin 42 is installed in the axial hole 412 in such a way that the locking section 422 slides in the axial hole 412.

[0043] Specifically, the telescopic pin 42 includes a main body section 423 extending from the locking section 422 to the head end, and the diameter of the main body section 423 is smaller than the diameter of the locking section 422. The elastic element 43 is composed of a spring sleeved on the main body section 423. Correspondingly, the axial hole 412 includes a primary stepped hole 4122 and a secondary stepped hole 4121 located inside the primary stepped hole 4122. The diameter of the secondary stepped hole 4121 is adapted to the diameter of the main body section 423 of the telescopic pin 42, and the diameter of the primary stepped hole 4122 is adapted to the diameter of the locking section 422. The telescopic pin 42 is assembled into the axial hole 412 by inserting the free end of the main body section 423 into the secondary stepped hole 4121 and sliding the locking section 422 within the primary stepped hole 4122. With the above structure, the telescopic pin 42 can be stably extended and retracted axially within the axial hole 42.

[0044] This utility model also provides a watch, including a watch head and a quick-release watch strap as described above.

[0045] 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.
