Description

Technical Field

[0001] This utility model relates to the technical field of spring bars, and more particularly to a quick-release watch strap and spring bars. Background Technology

[0002] Spring bars are an important connecting component in watches or wristbands, used to connect the watch strap to the watch case. To meet different needs, users frequently need to change watch straps. When changing a strap, the spring bars must first be unlocked to allow the strap to be removed from the case, then the new strap can be installed, and finally the spring bars must be reconnected to the case. Because the connection between the spring bars and the case is quite tight, it often requires professional tools to disassemble, or it can be done by a watch repair shop. Users often find it difficult to unlock the spring bars themselves, making strap replacement quite troublesome.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] This invention addresses the problem mentioned above where the spring bars are tightly connected to the watch case, often requiring professional tools for disassembly or a watch repair shop for disassembly, making it difficult for users to unlock the spring bars themselves and causing watch strap replacement to be very troublesome. This invention proposes a quick-release watch strap and spring bars.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A spring ear includes a spring ear shell, an unlocking member and a spring ear rod slidably disposed within the spring ear shell, and an unlocking drive mechanism. The unlocking drive mechanism includes a drive member disposed between the unlocking member and the spring ear rod, and a reset member connected to the drive member. The unlocking member and the drive member are slidably connected by a linkage structure, and the sliding direction of the unlocking member is perpendicular to the sliding direction of the drive member. The linkage structure causes the sliding of the unlocking member and the sliding of the spring ear rod to be linked, thereby driving the drive member to move within the spring ear shell and causing the spring ear rod to extend and retract within and outside the spring ear shell. The reset member is used to reset the drive member so that the spring ear rod extends outside the spring ear shell.

[0007] As described above, in a spring ear, the linkage structure includes a driving surface inclinedly disposed between the unlocking member and the driving member, the driving surface being at least one of the relative sliding surfaces between the unlocking member and the driving member, and the driving surface having a component force on the driving member that causes the driving member to slide into the spring ear shell along the retraction direction of the spring ear rod.

[0008] In the case of a spring ear as described above, the driving surface is a straight or curved surface.

[0009] As described above, the driving member includes a connecting portion connected to the spring bar, an extension portion disposed on one side of the connecting portion and connected to the reset member, the spring bar being axially connected to one side of the connecting portion, the extension portion and the connecting portion being radially distributed in the driving member along the spring bar, and the extension portion being away from the spring bar, the extension portion being slidably connected to the unlocking member through the linkage structure.

[0010] In the spring ear described above, the driving component is integrally formed with the spring ear rod.

[0011] As described above, in one type of spring ear, the driving component has a mounting portion located on one side of the linkage structure, the mounting portion being used to connect the reset component.

[0012] As described above, the new ear shell has a receiving cavity, a first sliding cavity and a second sliding cavity respectively communicating with the receiving cavity, an unlocking drive mechanism is disposed in the receiving cavity, the new ear rod is slidably disposed in the first sliding cavity, the new ear rod at least partially extends into the receiving cavity and is connected to the drive member, the unlocking member is slidably disposed in the second sliding cavity, the unlocking member at least partially extends into the receiving cavity and is slidably connected to the drive member through the linkage structure.

[0013] As described above, the new ear shell includes a first shell, a second shell and a third shell respectively disposed on both sides of the first shell, the first shell having the receiving cavity, the second shell having the first sliding cavity, and the third shell having the second sliding cavity. The second shell and the first shell are arranged along the axial direction of the new ear rod, and the third shell and the first shell are arranged along the radial direction of the new ear rod.

[0014] As described above, in a spring ear, the unlocking member has a limiting part located at the bottom and a relief groove located on one side of the limiting part. The driving member extends at least partially into the relief groove and is slidably connected to the unlocking member through the linkage structure. The limiting part is used to abut against the spring ear shell to restrict the unlocking member from disengaging from the second sliding cavity.

[0015] This utility model also provides a quick-release watch strap, including a watch strap body and spring bars as described above, wherein the spring bars are connected to the watch strap body.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model provides a spring bar that can be used in quick-release watch straps. The spring bar includes a spring bar housing, an unlocking component, a spring bar stem, and an unlocking drive mechanism. The unlocking component and the spring bar stem are slidably disposed in the spring bar housing. The unlocking drive mechanism is disposed between the unlocking component and the spring bar stem. The spring bar stem can extend and retract inside and outside the spring bar housing through the unlocking drive mechanism to achieve quick installation and removal of the spring bar relative to the watch case. By setting the unlocking drive mechanism between the unlocking component and the spring bar stem, users can remove the spring bar with one click, reducing the difficulty of installing and removing the spring bar and making it convenient for users to change watch straps themselves.

[0018] 2. In the unlocking drive mechanism, the unlocking component and the drive component are slidably connected through a linkage structure. The drive component drives the spring bar to extend and retract inside and outside the spring bar housing. In addition, the drive component can be automatically reset by a reset component, and the drive component drives the spring bar to automatically reset and extend to the outside of the spring bar housing. At the same time, the drive component can drive the unlocking component to reset and extend to the outside of the spring bar housing through the linkage structure. Users can remove and install the spring bar by simply pressing or releasing the unlocking component, thus realizing one-click removal and installation of the spring bar, greatly reducing the difficulty of removing and installing the spring bar, and making it convenient for users to remove and install the spring bar themselves to replace the watch strap.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0031] Example 1:

[0032] like Figure 1 As shown in Figure 8, this utility model provides a spring bar 1, which includes a spring bar housing 11, an unlocking component 12, a spring bar stem 13, and an unlocking drive mechanism 14. The unlocking component 12 and the spring bar stem 13 are slidably disposed in the spring bar housing 11, and the unlocking drive mechanism 14 is disposed between the unlocking component 12 and the spring bar stem 13. The spring bar stem 13 can extend and retract inside and outside the spring bar housing 11 through the unlocking drive mechanism 14 to achieve quick assembly and disassembly of the spring bar 1 relative to the watch case; in practical applications, such as Figure 5 and Figure 7 The diagram shows the retracted state of the spring bar 13. The user can directly press the unlocking member 12, which moves inward toward the inside of the spring bar housing 11 under pressure, and is driven by the unlocking drive mechanism 14 to retract the spring bar 13 into the spring bar housing 11. Figure 6 and Figure 8The diagram shows the spring bar 13 in its extended state. When the user releases the unlocking member 12, the unlocking member 12 can automatically extend the spring bar 13 to the outside of the spring bar housing 11 through the unlocking drive mechanism 14 to connect to the watch case. By setting the unlocking drive mechanism 14 between the unlocking member 12 and the spring bar 13, the user can remove the spring bar 1 with one click, reducing the difficulty of removing and installing the spring bar 1 and making it convenient for the user to change the watch strap.

[0033] In practical applications, spring bar 1 can be used with quick-release watch straps or with lanyards; this utility model does not impose specific limitations. When spring bar 1 is used with a watch strap, the user can use the spring bar to connect the watch strap to the watch case and wear the watch on their wrist. When spring bar 1 is used with a lanyard, the user can use the spring bar to connect the lanyard to the watch case and hang the watch on their neck, wrist, backpack, or other locations. It should be noted that when spring bar 1 is used with a lanyard, a separate through hole for connecting the lanyard can be provided in spring bar 1 to achieve the connection between the lanyard and spring bar 1. A corresponding fixing device can be provided on the lanyard to prevent the spring bar 1 from separating from the lanyard.

[0034] Furthermore, such as Figure 3As shown in Figure 8, the unlocking drive mechanism 14 includes a drive member 141 disposed between the unlocking member 12 and the spring bar 13, and a reset member 142 connected to the drive member 141. The unlocking member 12 and the drive member 141 are slidably connected by a linkage structure 15. The sliding direction of the unlocking member 12 is perpendicular to the sliding direction of the drive member 141, wherein the sliding direction of the unlocking member 12 is perpendicular to the axial direction of the spring bar 13, and the sliding direction of the drive member 141 is parallel to the spring bar 13. The spring ear rod 13 slides axially with the driving member 141; the linkage structure 15 causes the sliding of the unlocking member 12 and the sliding of the spring ear rod 13 to be linked, so as to drive the driving member 141 to move within the spring ear housing 11 and drive the spring ear rod 13 to extend and retract within and outside the spring ear housing 11; the reset member 142 is used to reset the driving member 141 so that the spring ear rod 13 extends outside the spring ear housing 11; optionally, the reset member 142 may be provided with The spring ear is an elastic element. In this embodiment, the unlocking element 12 and the driving element 141 are slidably connected by the linkage structure 15, and the driving element 141 drives the spring ear rod 13 to extend and retract inside and outside the spring ear shell 11. When assembling the spring ear 1, the driving element 141 can be automatically reset by the reset element 142, and the driving element 141 drives the spring ear rod 13 to automatically reset and extend to the outside of the spring ear shell 11. At the same time, the driving element 141 can drive the unlocking element 12 to reset and extend to the outside of the spring ear shell 11 through the linkage structure 15. Outside the ear housing 11, the user can detach and install the spring bar 1 simply by pressing or releasing the unlocking piece 12, thus realizing one-click detachment and installation of the spring bar 1, greatly reducing the difficulty of detaching and installing the spring bar 1, and making it convenient for users to detach and install the spring bar 1 themselves to replace the watch strap; in addition, when the spring bar stem 13 extends outside the spring bar housing 11 and is locked in the watch case, and the unlocking piece 12 is not pressed, the elastic pre-tightening force of the reset piece 142 can strengthen the connection between the spring bar stem 13 and the watch case, thereby improving the connection stability of the spring bar 1 and the watch strap body in the watch case.

[0035] Furthermore, such as Figure 4As shown in Figure 6, the linkage structure 15 includes a driving surface inclinedly disposed between the unlocking member 12 and the driving member 141. The driving surface is at least one of the relative sliding surfaces between the unlocking member 12 and the driving member 141. The driving surface has a component force on the driving member 141 that causes the driving member 141 to slide inward toward the inner side of the spring ear shell 11 along the retraction direction of the spring ear rod 13. In this embodiment, the driving surface is obliquely upward toward the retraction direction of the spring ear rod 13 from bottom to top. The linkage structure 15 includes a first linkage surface 151 disposed on the unlocking member 12 and a second linkage surface 152 disposed on the driving member 141 and corresponding to the first linkage surface 151. The first linkage surface 151 and the second linkage surface 152 are slidable. The unlocking member 12 and the driving member 141 are dynamically abutted to achieve a sliding connection between them. During the disassembly and assembly of the spring ear 1, there is relative sliding between the first linkage surface 151 and the second linkage surface 152. At least one of the first linkage surface 151 and the second linkage surface 152 forms the driving surface, that is, the driving surface can be set as the first linkage surface 151 and / or the second linkage surface 152. The driving surface cleverly links the unlocking member 12 and the driving member 141 to slide perpendicularly to each other. The driving surface has a component force that causes the driving member 141 to slide into the spring ear housing 11 along the retraction direction of the spring ear rod 13, so that the spring ear rod 13 can retract into the spring ear housing 11, thereby realizing the disassembly of the spring ear 1. Figure 5 and Figure 6 From the angle, the sliding direction of the unlocking member 12 relative to the spring ear housing 11 can be understood as longitudinal, and the sliding direction of the spring ear rod 13 and the driving member 141 relative to the spring ear housing 11 can be understood as transverse. In this embodiment, by setting the linkage structure 15 as an inclined driving surface, the longitudinal pressing force of the unlocking member 12 can be converted into a transverse pushing force on the driving member 141, which helps to reduce the force required by the user during operation, optimizes the user's feel when installing or removing the spring ear 1, and saves the installation space of the unlocking driving mechanism 14 in the spring ear housing 11, making the structure of the spring ear 1 more compact, reducing the volume of the spring ear 1, and simplifying the assembly of various components in the spring ear 1, which is conducive to improving the production efficiency of the spring ear 1. It should be noted that the above "longitudinal" and "transverse" are based on Figure 5 and Figure 6 From a practical application perspective, since the spring bar 1 is worn on the human arm through the main body of the watch strap, the sliding direction of the unlocking component 12 and the sliding direction of the spring bar 13 may change relative to the external environment.

[0036] Further optional, such as Figure 5 and Figure 6As shown, the driving surface can be configured as a straight surface or an arc surface, which has a simple structure and helps to reduce the manufacturing difficulty of the driving component 141 and the unlocking component 12, while reducing the assembly difficulty of the driving component 141 and the unlocking component 12, thereby further improving the production efficiency of the spring ear 1; for example, the first linkage surface 151 and the second linkage surface 152 can be configured as corresponding straight surfaces or arc surfaces at the same time. For another example, in the first linkage surface 151 and the second linkage surface 152, one linkage surface can be configured as a straight surface, and the other linkage surface can be configured as an arc surface corresponding to the straight surface. This utility model does not make specific limitations.

[0037] In another alternative embodiment of the raw ear 1, such as Figure 3 As shown in Figure 8, the driving member 141 includes a connecting portion 1411 connected to the spring bar 13, and an extension portion 1412 disposed on one side of the connecting portion 1411 and connected to the reset member 142. The spring bar 13 is axially connected to one side of the connecting portion 1411. The extension portion 1412 and the connecting portion 1411 are radially distributed in the driving member 141 along the spring bar 13, and the extension portion 1412 is away from the spring bar 13. The extension portion 1412 is slidably connected to the unlocking member 12 through the linkage structure 15. The spring bar 13 and the connecting portion 1411 are coaxially arranged. The extension portion 1412 is disposed on one side of the connecting portion 1411 along the radial direction L1 of the spring bar 13. The second linkage surface 152 is disposed on the extension portion 1412. The unlocking member 12 is slidably connected to the extension portion 1412 through the first linkage surface 151. The 12 components are distributed radially L2 along the spring bar 13, thereby forming an eccentric unlocking drive mechanism 14 relative to the spring bar 13. That is, the unlocking component 12 is in an eccentric position relative to the spring bar 13. When the unlocking component 12 slides relative to the spring bar housing 11, it applies an oblique component force to the drive component 141 and the spring bar 13. This oblique component force can better overcome the pre-tightening force of the reset component 142, thereby reducing the pressing force that the user needs to apply to the unlocking component 12, making the user's operation when installing or removing the spring bar 1 smoother and easier, and also reducing the burden on the unlocking component 12 and the drive component 141, thus extending the service life of the spring bar 1. In practical applications, the above-mentioned oblique component force can be decomposed by the drive surface that is inclined between the unlocking component 12 and the drive component 141 to form a component force that pushes the drive component 141 toward the inside of the spring bar housing 11, so as to realize the spring bar 13 retracting into the spring bar housing 11.

[0038] In another optional embodiment of the spring ear 1, the driving component 141 is integrally formed with the spring ear rod 13. Specifically, the driving component 141 can be injection molded onto the spring ear rod 13 using a corresponding injection mold to achieve the connection between the driving component 141 and the spring ear rod 13. This improves the connection strength between the spring ear rod 13 and the driving component 141, ensuring synchronous movement of the spring ear rod 13 and the driving component 141, thereby improving the extension and retraction efficiency of the spring ear rod 13, further optimizing the assembly and disassembly of the spring ear 1, and simplifying the assembly steps of the spring ear 1, thus improving the production efficiency of the spring ear 1. In addition, based on the integral forming of the driving component 141 and the spring ear rod 13, the reset component 142 is connected to the spring ear rod 13 through the driving component 141, which simplifies the assembly of the spring ear 1 and improves the production efficiency of the spring ear 1. Further optionally, the driving component 141 can be made of nylon, and the integral forming of the driving component 141 can improve the dimensional accuracy of the driving component 141.

[0039] In another alternative embodiment of the raw ear 1, such as Figure 4 As shown, the drive member 141 is integrally formed with the spring bar 13 through the connecting part 1411.

[0040] In another alternative embodiment of the raw ear 1, such as Figure 4 As shown, the driving member 141 has a mounting portion 1413 located on one side of the linkage structure 15. The mounting portion 1413 is used to connect the reset member 142. In this embodiment, the driving member 141 has the mounting portion 1413 on the side away from the spring ear rod 13. The mounting portion 1413 can be configured as a columnar mounting portion 1413 or a rod-shaped portion. The reset member 142 is sleeved on the outside of the mounting portion 1413. The structure is simple, which is conducive to improving the production efficiency of the spring ear 1 and facilitating the disassembly and replacement of the reset member 142. Further optionally, the mounting portion 1413 and the second linkage surface 152 are respectively located on both sides of the extension portion 1412.

[0041] In another alternative embodiment of the raw ear 1, such as Figure 3As shown in Figure 8, the spring ear shell 11 has a receiving cavity 111, a first sliding cavity 112 and a second sliding cavity 113 respectively communicating with the receiving cavity 111. The unlocking drive mechanism 14 is disposed in the receiving cavity 111, that is, the drive member 141 is slidably disposed in the receiving cavity 111, and the reset member 142 is disposed in the receiving cavity 111 and connected to the drive member 141. The spring ear rod 13 is slidably disposed in the first sliding cavity 112, and at least part of the spring ear rod 13 extends into the receiving cavity 111 and is connected to the drive member 141. The unlocking member 12 slides... The unlocking member 12 is movably disposed in the second sliding cavity 113, and at least partially extends into the receiving cavity 111 and is slidably connected to the driving member 141 through the linkage structure 15. Specifically, the first sliding cavity 112 and the receiving cavity 111 are distributed along the axial direction of the spring bar 13, and the second sliding cavity 113 and the receiving cavity 111 are distributed along the radial direction of the spring bar 13. The first sliding cavity 112 and the second sliding cavity 113 are respectively connected to both sides of the receiving cavity 111, so as to realize the eccentric structural distribution of the unlocking driving mechanism 14 relative to the spring bar 13.

[0042] Furthermore, such as Figure 3 As shown in Figure 8, the new ear shell 11 includes a first shell 114, a second shell 115, and a third shell 116 respectively disposed on both sides of the first shell 114. The first shell 114 contains the receiving cavity 111. The second shell 115 contains the first sliding cavity 112, which extends through the second shell 115 along its axial direction. The third shell 116 contains the second sliding cavity 113, which extends through the third shell 116 along its axial direction. The second shell 115 and the first shell 114 are arranged along the axial direction of the new ear rod 13. The third shell 116 and the first shell 116... 14 is arranged radially along the spring bar 13; specifically, the spring bar 13 is slidably disposed in the first sliding cavity 112 of the second housing 115, and can be guided by the second housing 115 to move telescopically relative to the second housing 115 along its axial direction, which helps to improve the movement stability of the spring bar 13. Similarly, the unlocking member 12 is slidably disposed in the second sliding cavity 113 of the third housing 116, and can be guided by the third housing 116 to move telescopically relative to the third housing 116 along the radial direction of the spring bar 13, which helps to improve the movement stability of the unlocking member 12, thereby improving the disassembly and assembly efficiency of the spring bar 1 and making it convenient for users to disassemble and assemble the spring bar 1 with one click.

[0043] In actual production, to further improve the assembly efficiency of the spring ear 1, the first housing 114, the second housing 115, and the third housing 116 can be processed independently. First, the unlocking component 12, the spring ear rod 13, and the unlocking drive mechanism 14 are installed in the first housing 114. Then, the second housing 115 and the third housing 116 are respectively fixedly installed on the first housing 114 by welding or other methods. Further optionally, the first housing 114 is provided with a positioning part 1141 for positioning the second housing 115. The second housing 115 is connected to the first housing 114 through the positioning part 1141, and the second housing 115 can at least partially extend into the receiving cavity 111. The position of the second housing 115 is first fixed by the positioning part 1141, and then further connected by welding or other methods. By pre-positioning the second housing 115 by the positioning part 1141, the assembly efficiency of the first housing 114 and the second housing 115 can be improved, and the alignment and communication between the first sliding cavity 112 and the receiving cavity 111 can be improved, making the sliding of the spring ear rod 13 smoother.

[0044] In another alternative embodiment of the spring ear 1, to further improve the reliability of the spring ear 1, such as... Figure 5 and Figure 6 As shown, the unlocking member 12 has a limiting part 121 at the bottom and a clearance groove 122 on one side of the limiting part 121. The driving member 141 extends at least partially into the clearance groove 122 and is slidably connected to the unlocking member 12 through the linkage structure 15. The limiting part 121 is used to abut against the spring ear shell 11 to restrict the unlocking member 12 from disengaging from the second sliding cavity 113. Specifically, the bottom of the unlocking member 12 is recessed upward to form the clearance groove 122. The limiting part 121 can be configured as limiting steps on both sides of the bottom of the unlocking member 12. The first linkage surface 151 is disposed between the limiting part 121 and the clearance groove 122. The sidewall of the clearance groove 122 is formed by the first linkage surface 151. The top of the extension block of the driving member 141 extends into the clearance groove 122 and is connected to the unlocking member 12 through the second linkage surface 152, thereby realizing the sliding connection between the unlocking member 12 and the driving member 141. Furthermore, the limiting part 121 is located outside the unlocking member 12. During the disassembly and assembly of the spring ear 1, the limiting part 121 is driven by the unlocking member 12 to move back and forth radially along the spring ear rod 13 between the spring ear shell 11 and the driving member 141, thereby limiting the sliding range of the unlocking member 12, which is beneficial to improving the disassembly and assembly efficiency and reliability of the spring ear 1.

[0045] Alternatively, a limiting structure corresponding to the limiting part 121 can be formed at the bottom of the third housing 116 or on the inner wall of the first housing 114. When the unlocking member 12 is reset, the unlocking member 12 drives the limiting part 121 to slide outward of the third housing 116 until it abuts against the limiting structure, thereby preventing the unlocking member 12 from disengaging from the second sliding cavity 113.

[0046] Example 2:

[0047] Based on any of the optional embodiments in Embodiment 1 above, Embodiment 2 provides another implementation of the raw ear 1, such as... Figure 3 As shown in Figure 8, spring bar stems 13 are slidably mounted on both sides of the spring bar housing 11. Unlocking mechanisms 14 are provided between the unlocking member 12 and the spring bar stems 13 on both sides, further improving the one-click installation and removal efficiency of the spring bar 1 and enhancing the connection stability of the spring bar 1 to the watch case. In practical applications, when disassembling the spring bar 1, the user presses the unlocking member 12, which, under force, moves towards the inside of the spring bar housing 11 in a direction perpendicular to the axial direction of the spring bar stem 13. The linkage structure 15 on both sides further drives the two driving members 141 towards the inside of the spring bar housing 11 in a direction parallel to the axial direction of the spring bar stem 13. The spring bars 1 slide towards each other, and simultaneously, the two driving components 141 drive the two spring bar stems 13 to retract into the spring bar housing 11, thereby separating the spring bar 1 from the watch case. At this time, the main body of the watch strap can be detached. When assembling the spring bar 1, the user releases the unlocking component 12, and the two driving components 141 move away from each other under the elastic force of the reset component 142, thereby driving the two spring bar stems 13 to extend to the outside of the spring bar housing 11, thereby locking the spring bar 1 in the watch case. At the same time, the two linkage structures 15 drive the unlocking component 12 to move and reset towards the outside of the spring bar housing 11, thereby realizing the automatic reset of the unlocking component 12, which facilitates the user to perform a new spring bar 1 disassembly operation.

[0048] Optionally, both drive members 141 are provided with mounting portions 1413, and the two ends of the reset member 142 are respectively sleeved on the outside of the two mounting portions 1413 and abut against the two drive members 141, which helps to simplify the assembly of the spring ear 1 and improve the production efficiency of the spring ear 1.

[0049] Example 3:

[0050] Based on the above embodiment one or embodiment two, this embodiment three provides a quick-release watch strap, such as... Figure 1 and Figure 2As shown, the quick-release watch strap includes a watch strap body and spring bars 1 connected to the watch strap body. The watch strap body includes an active end strap body 2a with a fastening element and a passive end strap body 2b that is fastened to the active end strap body 2a. At least one of the active end strap body 2a and the passive end strap body 2b has the spring bar 1. The watch strap body can also be a metal watch strap, leather watch strap, nylon watch strap, rubber watch strap, ceramic watch strap, braided watch strap, or other types of watch straps. This utility model does not make any specific limitation. The spring bar housing 11 is installed inside the watch strap body, and the unlocking element 12 can at least partially protrude to the outside of the watch strap body for the user to press and operate. By setting an unlocking drive mechanism 14 between the unlocking element 12 and the spring bar 13, the user can remove the spring bar 1 with one click, reducing the difficulty of removing and installing the spring bar 1 and making it convenient for the user to replace the watch strap.

[0051] It should be noted that the watch case is provided with a spring bar hole for connecting with the spring bar 13. Before the user releases the unlocking component 12, the spring bar 13 is aligned with the spring bar hole on the watch case. After the user releases the unlocking component 12, the spring bar 13 can extend out of the spring bar housing 11 through the unlocking drive mechanism 14 and be inserted into the spring bar hole, so that the watch strap body can be connected to the watch case.

[0052] Optional, such as Figure 1 and Figure 2 As shown, the exposed portion of the unlocking member 12 relative to the main body of the watch strap can face the user's wearing arm, or it can face the side away from the user's wearing arm.

[0053] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
