[0030] With the development of the economy, wrist-worn devices such as watches, bracelets, and bracelets have been widely developed, with more and more functions, and are sought after by the general public. In order to facilitate the wearing of wrist-worn devices, wrist-worn devices usually have straps, chains, and other belt structures. Due to the different thicknesses of the wearer's wrists, the length of straps and other belt structures is generally adjustable, thereby improving the comfort of the wearer when wearing. When adjusting the length of the current strap structure, it is necessary to use external tools to install or remove the beads on the strap, which increases the complexity of the disassembly and assembly process.

[0031] In view of this, the embodiment of the present invention proposes a strap, a watchband and a wrist-worn device, wherein an elastic limiting structure is provided between the first shaft portion of the first side bead and the second shaft portion of the second side bead, and the first shaft portion and the second shaft portion can be fixed by the elastic limiting structure, thereby completing the installation of the side bead; by overcoming the elastic force of the elastic limiting structure, pushing and pulling the first shaft portion and the second shaft portion, the first shaft portion and the second shaft portion can be separated, thereby completing the removal of the side bead. During the removal and assembly process of the side bead, no external tools are required, and direct manual operation is sufficient, which simplifies the complexity of the removal and assembly process and improves the convenience of operation.

[0032] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, a grain-belt is proposed in an embodiment of the present invention, comprising a center bead 10 and a first side bead 20 and a second side bead 30 arranged on both sides of the center bead 10, the first side bead 20 is provided with a first shaft portion 21, the second side bead 30 is provided with a second shaft portion 31, the first shaft portion 21 and the second shaft portion 31 are spliced ​​to form a rotating shaft rotatably connected to the center bead 10, wherein an elastic limiting structure 40 is provided between the first shaft portion 21 and the second shaft portion 31.

[0034] In the technical solution adopted in this embodiment, the first shaft portion 21 on the first side bead 20 and the second shaft portion 31 on the second side bead 30 are spliced to form a rotating shaft, and the rotating shaft penetrates through the middle bead 10, thereby fixing the first side bead 20 and the second side bead 30 on the opposite sides of the middle bead 10, so that the first side bead 20, the second side bead 30 and the middle bead 10 form a whole, realizing the rapid installation of the first side bead 20 and the second side bead 30. Moreover, the rotating shaft is rotatably connected to the middle bead 10, so that the angles of the first side bead 20 and the second side bead 30 can be conveniently adjusted. In addition, an elastic limiting structure 40 is provided between the first shaft portion 21 and the second shaft portion 31, and the elastic limiting structure 40 can be used to keep the first shaft portion 21 and the second shaft portion 31 relatively fixed and prevent the first shaft portion 21 and the second shaft portion 31 from separating from each other. At the same time, when separating the first shaft portion 21 and the second shaft portion 31, only the elastic force of the elastic limiting structure 40 needs to be overcome, and the first shaft portion 21 and the second shaft portion 31 are slid in the direction away from each other, and the separation of the first shaft portion 21 and the second shaft portion 31 can be simply and conveniently realized, and the rapid disassembly of the first side bead 20 and the second side bead 30 can be realized. The belt particle proposed in the embodiment of the present invention does not need to rely on external tools, and the first side bead 20 and the second side bead 30 can be directly manually pushed and pulled for disassembly, simplifying the disassembly and installation process of the side beads and improving the convenience of operation.

[0035] Specifically, the bead unit proposed in this embodiment includes a middle bead 10, a first side bead 20, a second side bead 30, and an elastic limiting structure 40, which can be applied to the watchbands of wrist-worn devices such as watches, bracelets, and bracelets, and are not limited here. Among them, the middle bead 10 is the main structure of the bead unit, and the first side bead 20 and the second side bead 30 are detachably arranged on opposite sides of the middle bead 10. To facilitate the disassembly and assembly of the first side bead 20 and the second side bead 30, through holes can be provided on the middle bead 10, and the through holes penetrate the middle bead 10. At the same time, a first shaft portion 21 is provided on the first side bead 20, and a second shaft portion 31 is provided on the second side bead 30. The first shaft portion 21 and the second shaft portion 31 are respectively inserted into the through holes from both sides of the middle bead 10, and the first shaft portion 21 and the second shaft portion 31 are pushed towards each other, so that the first shaft portion 21 and the second shaft portion 31 are spliced to form a rotating shaft, and the rotating shaft is rotatably arranged in the through hole. At this time, the first side bead 20 and the second side bead 30 are located on both sides of the middle bead 10. It can be understood that the middle bead 10 is sandwiched between the first side bead 20 and the second side bead 30, thus completing the installation of the first side bead 20, the second side bead 30 and the middle bead 10. In addition, an elastic limiting structure 40 is also provided between the first shaft portion 21 and the second shaft portion 31. The elastic limiting structure 40 can be used to limit the relative sliding between the first shaft portion 21 and the second shaft portion 31, so that the first shaft portion 21 and the second shaft portion 31 remain relatively fixed, and the firmness of the installation between the first side bead 20, the second side bead 30 and the middle bead 10 is improved. It can be understood that after the first shaft portion 21 and the second shaft portion 31 are spliced, the elastic limiting structure 40 deforms and has elasticity, and the elasticity generated by the elastic limiting mechanism makes the first shaft portion 21 and / or the second shaft portion 31 abut against the inner wall of the through hole of the middle bead 10. With the cooperation of the elastic limiting structure 40 and the through hole of the middle bead 10, the first shaft portion 21 and the second shaft portion 31 remain relatively fixed and prevent each other from separating. Moreover, when disassembling the first side bead 20 and the second side bead 30, only the elasticity of the elastic limiting structure 40 needs to be overcome, and the first shaft portion 21 and the second shaft portion 31 are pulled away from each other, so as to complete the disassembly of the first side bead 20, the second side bead 30 and the middle bead 10. In this embodiment, the elastic limiting structure 40 can be a spring, an elastic sheet, or a combination of a spring and other structures, and is not limited here.

[0036] It should be noted that at least two first shaft portions 21 and second shaft portions 31 are respectively provided and are all arranged at intervals along the length direction of the watchband. Among the two first shaft portions 21, one is selected to be connected to the middle bead 10, and the other is selected to be connected to the middle bead 10 in the adjacent bead unit; among the two second shaft portions 31, one is selected to be connected to the middle bead 10, and the other is selected to be connected to the middle bead 10 in the adjacent bead unit. In this way, the rapid disassembly and assembly of two adjacent bead units can be realized, and it is convenient to adjust the length of the watchband.

[0037] Further, referring to Figures 3 - 5, in an embodiment of the present invention, the elastic limiting structure 40 includes a limiting head 41, an elastic member 42 connected to the limiting head 41, and a limiting groove 43 cooperating with the limiting head 41. The limiting head 41 and the elastic member 42 are provided on one of the first shaft portion 21 and the second shaft portion 31, and the limiting groove 43 is provided on the other of the first shaft portion 21 and the second shaft portion 31. The elastic member 42 has a tendency to move the limiting head 41 in a direction approaching the limiting groove 43.

[0038] In this embodiment, the elastic limiting structure 40 includes a limiting head 41, a limiting groove 43 and an elastic member 42. The limiting head 41 is disposed at one end of the elastic member 42, and the limiting groove 43 is used to cooperate with the limiting head 41. It can be understood that the limiting head 41 extends into the limiting groove 43 under the elastic force of the elastic member 42, and the cooperation of the limiting head 41, the limiting groove 43 and the elastic member 42 is used to limit the axial movement of the first shaft portion 21 and the second shaft portion 31. Among them, the limiting groove 43 can be disposed on the first shaft portion 21, while the elastic member 42 is disposed on the second shaft portion 31, and the limiting head 41 is disposed at one end of the elastic member 42 away from the second shaft portion 31; the limiting groove 43 can also be disposed on the second shaft portion 31, while the elastic member 42 is disposed on the first shaft portion 21, and the limiting head 41 is disposed at one end of the elastic member 42 away from the first shaft portion 21. The setting positions of the limiting groove 43 and the elastic member 42 are not limited herein, and in actual applications, they can be preferentially selected. For the convenience of description, in this embodiment, the case where the elastic member 42 is disposed on the first shaft portion 21 and the limiting groove 43 is disposed on the second shaft portion 31 is taken as an example for description. When the first shaft portion 21 and the second shaft portion 31 are inserted into the through hole of the middle bead 10 for splicing, the limiting head 41 abuts against the side surface of the second shaft portion 31 facing the first shaft portion 21, and at the same time, the elastic member 42 is compressed to generate an elastic force. As the first shaft portion 21 and the second shaft portion 31 continue to be inserted, the first shaft portion 21 and the second shaft portion 31 are spliced to form a rotating shaft. At this time, the limiting head 41 slides into the limiting groove 43 under the elastic force of the elastic member 42, and the limiting head 41 has a tendency to abut against the bottom of the limiting groove 43. At the same time, the side surfaces of the first shaft portion 21 and the second shaft portion 31 facing away from each other abut against the inner wall of the through hole of the middle bead 10, so that the limiting of the first shaft portion 21 and the second shaft portion 31 in the axial direction of the rotating shaft can be realized, and the first shaft portion 21 and the second shaft portion 31 are in a relatively fixed state, thereby realizing the installation and fixation of the first side bead 20, the second side bead 30 and the middle bead 10. When it is necessary to disassemble the first side bead 20 and the second side bead 30, overcome the elastic force of the elastic member 42, pull the first shaft portion 21 and the second shaft portion 31 in a direction away from each other, the elastic member 42 is compressed, the limiting head 41 slides out of the limiting groove 43, and continue to pull the first shaft portion 21 and the second shaft portion 31 until the first shaft portion 21 and the second shaft portion 31 are separated from each other, so as to remove the first side bead 20 and the second side bead 30 from the middle bead 10. During the entire disassembly and assembly process of the first side bead 20 and the second side bead 30, no external tool is required, and direct manual operation can be realized, which is simple and convenient.

[0039] Further, in an embodiment of the present invention, in the axial direction of the rotating shaft, at least two groups of elastic limiting structures 40 are provided. By providing at least two groups of elastic limiting structures 40, the limiting can be performed at multiple different positions of the first shaft portion 21 and the second shaft portion 31, thereby improving the reliability of the axial limiting of the first shaft portion 21 and the second shaft portion 31.

[0040] Further, see Figure 4 and Figure 5 In one embodiment of the present invention, the two limiting heads 41 in the two groups of elastic limiting structures 40 are both arranged on the first shaft portion 21. It can be understood that the limiting heads 41 in the first group of elastic limiting structures 40 are arranged on the first shaft portion 21, and the limiting grooves 43 in the first group of limiting structures are arranged on the second shaft portion 31, while the limiting heads 41 in the second group of elastic limiting structures 40 are arranged on the first shaft portion 21, and the limiting grooves 43 in the second group of limiting structures are arranged on the second shaft portion 31. Of course, in another embodiment, the two limiting heads 41 in the two groups of elastic limiting structures 40 are respectively arranged on the first shaft portion 21 and the second shaft portion 31. It can be understood that the limiting heads 41 in the first group of elastic limiting structures 40 are arranged on the first shaft portion 21, and the limiting grooves 43 in the first group of limiting structures are arranged on the second shaft portion 31, while the limiting heads 41 in the second group of elastic limiting structures 40 are arranged on the second shaft portion 31, and the limiting grooves 43 in the second group of limiting structures are arranged on the first shaft portion 21. In this embodiment, the arrangement positions of the limiting heads 41 and the limiting grooves 43 in the two sets of elastic limiting structures 40 are not limited, and they can be selected and used in actual application.

[0041] Further, in one embodiment of the present invention, the side of the limit head 41 facing away from the elastic member 42 is a spherical surface or a conical surface. The spherical surface or conical surface of the limit head 41 can play the role of a guide surface, which is convenient for the limit head 41 to slide into or out of the limit groove 43. In another embodiment, the limit groove 43 is a spherical surface or a conical surface, which can also play the role of a guide surface, which is convenient for the limit head 41 to slide into or out of the limit groove 43. It should be pointed out that any one of the limit head 41 and the limit groove 43 can be set as a spherical surface or a conical surface, or can be set as a conical surface or a spherical surface at the same time, which is not limited here.

[0042] Furthermore, in one embodiment of the present invention, the side beads are made of plastic; and / or the first shaft portion 21 and the second shaft portion 31 are made of metal. In this embodiment, the plastic material is relatively light, which can reduce the overall weight of the beads and reduce the pressure on the wearer's wrist. The first shaft portion 21 and the second shaft portion 31 need to bear or support the middle bead 10, and must have sufficient strength, while the metal material is relatively hard and can meet the demand for supporting the middle bead 10. Preferably, the material of the first side bead 20 and the second side bead 30 is stainless steel. It should be pointed out that the first shaft portion 21 and the second shaft portion 31 are flat on one side facing each other, which can increase the contact area between the first shaft portion 21 and the second shaft portion 31, and is conducive to the relative sliding of the first shaft portion 21 and the second shaft portion 31.

[0043] Further, in an embodiment of the present invention, the first shaft portion 21 and the first side bead 20 are integrally formed; and / or, the second shaft portion 31 and the second side bead 30 are integrally formed. In this embodiment, through the integral forming process, the overall structural strength can be improved, damage can be prevented, thereby extending the service life and reducing the use and maintenance costs. Preferably, the integral forming can be injection molding or overmolding, which is not limited herein.

[0044] Further, in an embodiment of the present invention, the material of the middle bead 10 is a hard material. In order to prevent the middle bead 10 from deforming and affecting the splicing of the first side bead 20 and the second side bead 30, the middle bead 10 can be made of a hard material. Preferably, the hard material can be any one of metal, plastic, and Corian.
