[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] The interlocking mechanism of the arc-shaped groove 24 between the first snap plate 22 and the second snap plate 23, combined with the automatic reset function of the reset spring 25, forms a double locking effect. Compared with the single-point fixation of the traditional spring rod, the curved surface contact of the arc-shaped groove 24 can effectively disperse stress when subjected to external impact, greatly reducing the risk of accidental detachment and solving the problem of easy loss of traditional spring ears.
[0025] like Figure 1-5 As shown, this utility model discloses a watch buckle structure, including a support component, a limiting component, a buckle component, and a connecting part. The limiting component is disposed on the inner side wall of the support component, and the buckle component is disposed on the inner side wall of the limiting component for connecting the watch strap. The connecting part is disposed between the support components to facilitate the connection of the support components. The buckle component includes a buckle housing 21, a first buckle plate 22, and a second buckle plate 23. The buckle housing 21 is disposed on the inner side wall of the limiting component, the first buckle plate 22 is disposed on the inner side wall of the buckle housing 21, and the second buckle is disposed on the inner side wall of the buckle housing 21 and cooperates with the first buckle plate 22 and the second buckle.
[0026] The first buckle plate 22 extends outward and is provided with an arc-shaped groove 24. The arc-shaped groove 24 is respectively provided on the inner sidewall of the first buckle plate 22 and the second buckle plate 23. The first buckle plate 22 extends outward and is provided with a reset spring 25. The reset spring 25 is respectively provided at one end of the first buckle plate 22 and the second buckle plate 23, so as to facilitate the reset of the buckle plate.
[0027] Specifically, when the watch strap is inserted into the clasp assembly, the arc-shaped grooves 24 of the first clasp plate 22 and the second clasp plate 23 form a misaligned engagement. The preload of the return spring 25 pushes the clasp plate inward to press the watch strap, and its arc-shaped contact surface generates a normal component force, so that the watch strap is simultaneously subjected to lateral compression and longitudinal locking resistance, forming a self-locking effect. When disassembly is required, pressing the folding clasp 201 triggers the unlocking mechanism, and the spring force drives the clasp plate to expand outward along the limiting trajectory of the notch groove 311, releasing the interlocking state of the arc-shaped groove 24.
[0028] It also includes a folding buckle 201 and a strap buckle 210. The folding buckle 201 is located on the upper surface of the support component and is used to limit the support component. The strap buckle 210 is located on the back of the support component and is used to limit the strap.
[0029] Specifically, when the operator presses the folding buckle 201, the unlocking mechanism is triggered: the folding buckle 201 rotates the upper folding piece 11 via the movable shaft 41, causing the groove 301 on its inner side to disengage from the limiting protrusion of the buckle housing 21. This action simultaneously releases the axial constraint of the buckle housing 21, and the first buckle plate 22 automatically returns to its original position under the action of the return spring 25, causing the second buckle plate 23 to exit the arc-shaped groove 24, completing the unlocking process. The entire unlocking process amplifies the operating force through the lever principle, achieving single-handed pressing disassembly.
[0030] The limiting component includes a placement groove 31, which is disposed on the inner sidewall of the support component and is used to limit the locking component. The locking housing 21 is located on the inner sidewall of the placement groove 31; and
[0031] Groove 301 is provided on the inner side wall of the support component and is used to limit the folding buckle 201;
[0032] The mounting groove 310 is formed on the inner side wall of the snap-fit housing 21 and is used to limit the snap-fit plate.
[0033] Specifically, the placement groove 31 fully encloses and constrains the snap-fit housing 21, and together with the installation groove 310, it limits the axial movement of the snap-fit plate, forming a three-dimensional spatial constraint system.
[0034] The Z-shaped limiting rail of the folding buckle 201 cooperates with the groove 301 of the support component to limit the folding angle within the range of 0-30°, which ensures wearing comfort and prevents excessive folding from causing structural failure.
[0035] It also includes a notch 311, which is formed on the inner side wall of the snap-fit housing 21. A limiting block 312 extends outward from the notch 311 and is provided on one side wall of the snap-fit housing 21 to limit the arc-shaped groove 24.
[0036] Specifically, when subjected to unexpected tension, the snap-fit plate transmits the force to the trapezoidal cross-section of the limiting block 312. Its 45° inclined surface design decomposes the vertical tension into a horizontal component and a vertical reaction force. The horizontal component pushes the snap-fit plate to slide along the notch 311, while the vertical reaction force compresses the return spring 25 to store energy. When the external force disappears, the spring potential energy is released, pushing the snap-fit plate to reset. The wedge-shaped structure of the limiting block 312 ensures that the snap-fit plate accurately returns to the locked position.
[0037] It also includes a limiting plate 320 and a viewing groove 330. The limiting plate 320 is located at one end of the support component and is used to limit the watch strap. The viewing groove 330 is opened on the inner side wall of the buckle housing 21 to facilitate observation of the inside of the buckle component.
[0038] Specifically, the observation groove 330 allows direct observation of the working status of the return spring 25 and the wear condition of the arc groove 24, thus improving practicality.
[0039] The connecting part includes a movable shaft 41, which is respectively disposed between the support components. A connecting rod 42 extends inward from the movable shaft 41 and is disposed on the inner side wall of the movable shaft 41 to facilitate the connection of the support components.
[0040] Specifically, the movable shaft 41 transmits torque through the connecting rod 42, allowing the upper folding piece 11 and the lower folding piece 12 to rotate around the shaft. When adjusting the strap length, the folding pieces open and close at a controllable angle along the movable shaft 41, and the limiting plate 320 adjusts the strap contact surface synchronously with the movement trajectory of the folding pieces. This mechanism supports stepless adjustment within the range of 15° to 180°, and with the surface compensation of the arc groove 24, it ensures a good fit for wrists with different curvatures.
[0041] The support assembly includes an upper folding piece 11 and a lower folding piece 12. The upper folding piece 11 is located at one end of the lower folding screen. A folding buckle 201 is located on the upper surface of the lower folding piece 12. A watch strap buckle 210 is located on the back of the lower folding piece 12. A groove 301 is located on the inner sidewall of the upper folding piece 11. A limiting plate 320 is located at one end of the lower folding piece 12. A movable shaft 41 is located between the upper folding piece 11 and the lower folding piece 12.
[0042] Specifically, the buckle 210 engages with the strap holes via the stepped toothed structure of the limiting plate 320. When length adjustment is needed, the buckle 210 is pulled outward to release the limiting mechanism. After the strap is slid to the desired position, the hook structure of the buckle 210 automatically engages with the next tooth under the action of a spring. The upper and lower folding pieces 12 connected by the movable shaft 41 can rotate relative to each other, ensuring a good fit between the strap and the wrist at different wearing angles.
[0043] The upper folding piece 11 extends outward to provide a buckle body 13, which is located at one end of the upper folding piece 11, and the placement groove 31 is located on the inner side wall of the buckle body 13.
[0044] Specifically, the buckle body 13 is mainly used to protect the internal structure of the buckle assembly, preventing the buckle assembly from being damaged by external influences, thus improving its practicality.
