[0002] Generally, in order to cover the wrists of some customers with thicker wrists, the length of the watch metal band is set to a longer length when leaving the factory. However, for most customers, several links need to be removed to fit their wrist sizes. Generally, the removal of the watch band links requires professionals to use special tools. To facilitate consumers to adjust the length of the watch band by themselves to fit their wrist sizes, the existing solution is designed as shown in Figure 1 、 2 When this kind of watch band needs to remove a link, it is necessary to push structures B1 and B2 to make the compression spring contract horizontally and disengage from the previous link, so as to remove the redundant link and adjust the length of the watch band. For the convenience of operation, B1 and B2 need to protrude from the bottom of the watch band, which has a certain impact on the wearing comfort. At the same time, when removing the link of this structure, it is necessary to continuously apply horizontal force with nails or fingers to press the internal spring. However, due to the limited space, B1 and B2 are usually small, and the operation is not very convenient. Therefore, this solution needs to be further improved to improve the wearing comfort and operation experience.

[0031] To facilitate the understanding of the present invention, the following will describe the present invention more comprehensively with reference to the relevant drawings. The typical embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0032] Refer to Figure 3 、 7, 8. The strap links of the present utility model are sequentially connected to form a strap. The direction in which the respective links are sequentially connected is the length direction of the strap. The width direction of the strap is perpendicular to the length direction of the strap. In this embodiment, the length direction of the strap is defined as the front-back direction, the width direction of the strap is defined as the left-right direction, and the thickness direction of the strap is defined as the up-down direction.

[0033] The structure of a single link can refer to Figure 3 . A single link includes a middle bead module and a first side bead 1 and a second side bead 2 connected to two opposite sides of the middle bead module. The first side bead 1 and the second side bead 2 are disposed opposite to each other in the left-right direction (i.e., the width direction of the strap) and are both disposed offset from the middle bead module, so that the middle bead module of other links can be movably strung between the first side bead 1 and the second side bead 2. The portions of the first side bead 1 and the second side bead 2 that protrude offset from the middle bead module are used to connect to the next link, and the portions of the middle bead module that protrude offset from the first side bead 1 and the second side bead 2 are used to connect to the previous link.

[0034] In the present utility model, the middle bead module is composed of a plurality of (a plurality means two or more) middle beads. Specifically, the middle bead module includes a first middle bead 3 and a second middle bead 4. The first middle bead 3, the second middle bead 4, and the first side bead 1 are sequentially arranged side by side in the width direction of the strap, and the first middle bead 3 and the first side bead 1 are elastically connected in the width direction of the strap by a first elastic member 6 that movably passes through the second middle bead 4. The first middle bead 3 and the second middle bead 4 partially overlap in the thickness direction of the strap, and the overlapping portion jointly sandwiches a second elastic member 7. The first elastic member 6 is provided with a position for cooperating with the second middle bead 4. The second elastic member 7 provides an elastic force in the thickness direction of the strap so that the second middle bead 4 is engaged and locked with the position of the first elastic member 6. When the first elastic member 6 is locked, it is in a state of storing energy (i.e., a deformed state, providing an elastic force externally); when the second middle bead 4 is pressed to overcome the elastic force of the second elastic member 7, the second middle bead 4 is unlocked from the position of the first elastic member 6, and after the first elastic member 6 is unlocked, it pushes the first middle bead 3 away from the second middle bead 4 based on its elastic force in the width direction of the strap, so as to increase the distance between the first side bead 1 and the second side bead 2 for taking out or inserting other links.

[0035] To achieve appearance symmetry, in this embodiment, the middle bead module further includes a third middle bead 5 located between the first middle bead 3 and the second side bead 2. It can be understood that in other embodiments, the third middle bead 5 can also be omitted, and the first middle bead 3 and the second side bead 2 are directly assembled together. In this embodiment, the first middle bead 3, the third middle bead 5, and the second side bead 2 are fixedly connected. All the middle beads 3, 4, 5 have the same length and are arranged in alignment along the width direction of the watch band, and the module formed together is equivalent to a single bead in appearance. In this embodiment, the widths of the first middle bead 3 and the third middle bead 5 are the same and much smaller than the width of the first middle bead 3 located at the center.

[0036] Specifically, in combination with Figure 4-5 , the second middle bead 4 includes a main body portion and an extension portion 401. The extension portion 401 extends towards the first middle bead 3. The main body portion is arranged side by side with the first middle bead 3 in the width direction of the watch band. The extension portion 401 is connected to the edge of the main body portion close to the first middle bead 3, and the surfaces of the extension portion 401 and the main body portion are smoothly transitioned without protrusions. The extension portion 401 is equivalent to a small piece extending from the edge of the surface of the main body portion. A receiving groove 301 is formed by recessing on the first middle bead 3. The second elastic member 7 is installed at the bottom of the receiving groove 301. The extension portion 401 is completely received in the receiving groove 301 and presses against the second elastic member 7. More specifically, the shape of the receiving groove 301 is the same as the shape of the extension portion 401, and the depth of the receiving groove 301 is greater than the thickness of the extension portion 401. When the second middle bead 4 is locked with the first elastic member 6, the extension portion 401 and the surface of the first middle bead 3 form a smoothly transitioned appearance surface. The second elastic member 7 is specifically a second spring. An installation hole adapted to the second elastic member 7 is opened at the bottom of the receiving groove 301. The second elastic member 7 is inserted into the installation hole and protrudes from the installation hole to abut against the extension portion 401.

[0037] Referring to Figure 6-7 , Figure 6 shows Figure 3The cross-section at the position indicated by the arrow. The first elastic member 6 includes a screw 61 and a first spring 62. The first spring 62 and the screw 61 are arranged in the first middle bead 3 along the width direction of the watch band. The first spring 62 abuts against the screw 61. The screw 61 passes through the second middle bead 4 movably and is threadedly connected to the first side bead 1. The section of the screw 61 passing through the second middle bead 4 is recessed to form a groove 6121 as the clamping position. More specifically, the screw 61 includes a nut 611, a screw rod 612, and a screw tail 613 connected in sequence. Only the screw tail 613 is threaded and is threadedly connected to the first side bead 1. The thread accounts for about one-fifth of the total length of the screw 61. The position of the screw rod 612 close to the screw tail 613 is reduced in diameter to form a circular groove, and this circular groove is the groove 6121. The first spring 62 and the nut 611 are located inside the first middle bead 3, and the screw rod 612 passes through the first middle bead 3 and the second middle bead 4 in sequence.

[0038] The second elastic member 7 jacks up the second middle bead 4 until the main body portion of the second middle bead 4 is clamped into the groove 6121, as shown in Figure 6 (a) in. When the second middle bead 4 is jacked up and clamped into the groove 6121, the screw 61 cannot move. At this time, the first spring 62 is in a compressed state and provides an elastic force pointing to the first side bead 1. When pressing down the extension portion 401 of the second middle bead 4, as shown by the arrow in Figure 6 (b), the second middle bead 4 disengages from the groove 6121 and cannot restrict the screw 61. The elastic force of the first spring 62 pushes the first spring 62 outward (i.e., in the direction towards the first side bead 1). At this time, the second middle bead 4 is blocked by the screw rod 612 and remains in the pressed state and cannot rebound. At this time, the belt section to be removed can be taken off. If a new belt section needs to be assembled, it can also be assembled at this time. When the user presses the first side bead 1 inward (i.e., in the direction towards the second middle bead 4), it can be restored to the state shown in Figure 6 (a).

[0039] Refer to Figure 7 , specifically, a threaded hole 12 matching the screw 61 is opened inside the first side bead 1. A stepped hole 31 (i.e., a countersunk hole, which includes a large hole and a small hole) matching the screw 61 is penetrated and opened inside the first middle bead 3. A screw rod through hole 41 is opened in the second middle bead 4. The aperture size of the screw rod through hole 41 is not less than the radial size of the screw rod 612 of the screw 61.

[0040] Combined with Figure 3 、 7The first spring 62 and the nut 611 are located in the large hole of the stepped hole 31, and one end of the first spring 62 abuts against the side of the nut 611 of the screw 61 away from the screw rod 612, and the other end of the first spring 62 abuts against the third middle ball 5. The screw rod 612 of the screw 61 passes through the stepped hole 31 and the screw rod through hole 41 in sequence, and the screw tail 613 is threadedly matched with the threaded hole 12.

[0041] The following introduces other connection details between the beads inside the band section: the first side bead 1 is also connected to the first middle bead 3 and the second middle bead 4 through the first band section inner pin 83, the second side bead 2 is connected to the third middle bead 5 and the first middle bead 3 through the second band section inner pin 84, and the second side bead 2 is also connected to the third middle bead 5 through the third band section inner pin 85. Specifically, in this embodiment, the first band section inner pin 83 is a single-head knurled pin, the third band section inner pin 85 is a full knurled pin, and the second band section inner pin 84 is a double-head knurled pin. The middle bead module is penetrated and opened with a first straight hole extending along the width direction of the watch band. The first straight hole is composed of three through holes 52, 32, and 42 that penetrate the third middle bead 5, the first middle bead 3, and the second middle bead 4. The first side bead 1 has a first connection hole 13 that is opposite to the through hole 42, and the second side bead 2 has a second connection hole 23 that is opposite to the through hole 52. The first belt section inner pin 83 is movably plugged into the through holes 32 and 42, and one end of the knurling is fixedly connected to the first connecting hole 13. The second belt section inner pin 84 is movably passed through the through hole 52, and the two ends of the knurling are fixedly connected to the through hole 32 and the first connecting hole 13 respectively. The third center bead 5 also has a third connecting hole 51, and the second side bead 2 also has a fourth connecting hole 22 facing the third connecting hole 51. The third belt section inner pin 85 is fixedly connected to the third connecting hole 51 and the fourth connecting hole 22 respectively. The third connecting hole 51 is preferably facing the stepped hole 31 but has a smaller hole diameter than the stepped hole 31 (to facilitate the support of the first spring 62).

[0042] Regarding the connection with internodes: A second through hole extending in the width direction of the watch band is formed through the protruding part of the middle bead module relative to the first side bead 1 and the second side bead 2. The second through hole is composed of three through holes 53, 33, and 43 that penetrate the third middle bead 5, the first middle bead 3, and the second middle bead 4. A fifth connection hole 11 is formed in the protruding part of the first side bead 1 relative to the middle bead module, and a sixth connection hole 21 facing the middle bead is formed in the protruding part of the second side bead 2 relative to the middle bead module. The second through hole of one watch band section and the fifth connection hole 11 and the sixth connection hole 21 of another watch band section are connected through watch band section connectors 81 and 82. Specifically, the watch band section connectors 81 and 82 are both single-headed roll pins. The watch band section connector 81 is movably inserted into the through holes 43 and the connection hole 11, and the knurled end is fixedly connected to the through hole 33; the watch band section connector 82 is movably inserted into the through holes 53 and the connection hole 21, and the knurled end is fixedly connected to the through hole 33. Of course, the watch band section connectors 81 and 82 can be replaced by a key pin.

[0043] In this embodiment, the through hole 33, the stepped hole 31, and the through hole 32 are arranged in sequence and evenly spaced; similarly, the through hole 53, the through hole 52, and the connection hole 51 are arranged in sequence and evenly spaced, and similarly, the through hole 43, the through hole 42, and the screw through hole 41 are arranged in sequence and evenly spaced. The connection holes 21, 22, and 23 are blind holes and are arranged in sequence and evenly spaced. The connection holes 11, the threaded hole 12, and the connection hole 13 are arranged in sequence and evenly spaced, and the connection holes 11 and 13 are also blind holes. For better pressing effect, in this embodiment, the receiving groove 301 is formed above the stepped hole 13, and the mounting hole of the second elastic member 7 is located between the stepped hole 31 and the through hole 32.

[0044] In addition, although the first middle bead 3, the third middle bead 5, and the second side bead 2 are fixedly connected in this embodiment, in fact, the assembly method of the first middle bead 3, the third middle bead 5, and the second side bead 2 can also be designed to be the same as the assembly method of the first middle bead 3, the second middle bead 4, and the first side bead 1. For example, there is also partial overlap between the first middle bead 3 and the third middle bead 5, and the overlapping part is jointly clamped with an elastic member identical to the second elastic member 7. The first middle bead 3 and the second side bead 2 are also elastically connected in the width direction of the watch band through an elastic member identical to the first elastic member 6 that passes through the third middle bead 5 movably.

[0045] The process of adjusting the length of the watch band in this embodiment is introduced below:

[0046] As Figure 8As shown in (a) therein, it is in the locked state at this time. The middle bead 4 is fitted into the groove of the screw 61, so that the screw 61 is restricted by the middle bead 4 and cannot move. At this time, the spring 62 is in a compressed state. Press the extension 401 of the middle bead 4, then the middle bead 4 deflects downward and loses the restriction on the screw 61. The screw 61 pops out under the elastic force of the spring 62, bringing out the edge bead 1, and the belt section A is unlocked, as Figure 8 shown in (b) therein. At this time, the stepped hole 31 restricts the nut 611 of the screw 61 to prevent the middle bead 4 and the edge bead 1 from completely separating. Take out the belt section A downward to complete the removal of the belt section A, as Figure 8 shown in (c) therein. If there is no need to assemble a new belt section, while pressing the extension 401 of the middle bead 4, push the edge bead 1 inward. That is, the disassembly process of the belt section A is state (a) → state (b) → state (c). The assembly process of the belt section is the opposite. After loading the belt section A upward, while pressing the extension 401 of the middle bead 4, push the edge bead 1 inward, release the middle bead 4, the screw 61 is restricted, and the belt section A is locked to complete the assembly of the belt section A. That is, the assembly process of the belt section A is state (c) → state (b) → state (a).

[0047] In summary, the utility model uses one of the beads in the multi-bead watchband as an operating part, without additionally adding a lever or other parts, and designs a pressing unlocking structure. When the middle bead used as the operating part is pressed down, the edge beads of the belt section are released from the locked state and pop out a certain distance outward, so that the matching width between the belt sections increases, and the subsequent belt sections can be conveniently taken out; after taking out one belt section, connect the remaining watchband and press the edge bead inward to restore the initial state; by operating in sequence, several belt sections can be intercepted from the watchband until the length of the watchband meets the needs of consumers. Compared with the prior art, the utility model retains the appearance design of the multi-bead watchband, there are no protruding parts on the whole watchband, it fits the wrist and is comfortable to wear; at the same time, it adopts a pressing unlocking operation method, without borrowing any tools, and can complete the disassembly and assembly of the belt section with a light press of the finger, meeting the adjustment needs of consumers.
