[0028] See also Figure 1-7, which is a bracelet lock structure 100 provided by the utility model. The bracelet lock structure 100 includes a first lock body 10, a second lock body 20, and a seesaw assembly 30 rotatably connected to the second lock body 20 and engaged with the first lock body 10; the seesaw assembly 30 includes a seesaw clip 31, an elastic member for elastically connecting the seesaw clip 31 to the first lock body 10, and a rotating pin 33 for rotatably connecting the seesaw clip 31 to the second lock body 20. A snap structure is provided on the seesaw clip 31 and the first lock body 10. Pressing the bottom of the seesaw clip 31 separates the snap structure to release the engaged state of the seesaw clip 31 and the first lock body 10. The lock structure 100 of the bracelet provided by the present invention locks the first lock body 10 and the second lock body 20 by utilizing the seesaw clamp 31 and the buckle structure on the first lock body 10, and utilizes the elastic member to provide elastic force for the seesaw clamp 31 and the second lock body. It can effectively ensure the locking force between the first lock body 10 and the second lock body 20 while compensating for the small elastic deformation of the decorative lock buckle caused by materials such as gold, silver, copper, and tin, ensuring the rebound force, and avoiding the bracelet lock being unlocked due to insufficient locking force, resulting in the bracelet falling off and causing economic losses to the user; in addition, by pressing the bottom of the seesaw clamp 31 to separate the buckle structure, the engagement state of the seesaw clamp 31 and the first lock body 10 can be released, which can effectively improve the convenience of user operation and enhance the user experience during use.

[0029] like Figure 1 、 Figure 2 and Figure 6 、 Figure 7 As shown, in the embodiment provided by the present invention, the buckle structure includes a hook 311 provided on the rocker clip 31 and a first slot 11 provided on the first lock body 10. The hook 311 is embedded in the first slot 11 on the first lock body 10 under the elastic force of the elastic member. The first bracelet body 10 and the second lock body 20 are respectively connected to the first bracelet body. The first slot 11 is provided at the bottom of the first lock body 10. The second lock body 20 includes a connecting portion 21 and a guide portion 22 located on the connecting portion 21. The rocker clip 31 is rotatably connected to the connecting portion 21. By providing the first slot 11 at the bottom of the first lock body 10, the accuracy with which the hook 311 of the rocker clip 31 is embedded in the first slot 11 of the first lock body 10 can be effectively improved, thereby ensuring the stability of the rocker clip 31 and the first lock body 10 being fixed by the buckle structure. In addition, in the original state, the hook 311 is embedded in the first latch 11 on the first lock body 10 under the action of the elastic force of the elastic part, which can effectively ensure the stability of the clamping and fixing between the first lock body 10 and the second lock body 20, and then ensure the stability of the clamping and fixing between the first bracelet body and the second bracelet body, avoiding the separation of the first bracelet body and the second bracelet body, causing the bracelet to fall off, causing economic losses to the user.

[0030] like Figure 4-Figure 7 As shown, in the embodiment provided by the present invention, the elastic member is a U-shaped spring clip 32. The interior of the second lock body 20 is a hollow structure, which, together with the seesaw clamp 31, forms a mounting space for the U-shaped spring clip 32. The seesaw clamp 31 also includes a circular arc surface 312 that is flush with the outer edges of the first and second bracelet bodies. Decorative surfaces 313 are provided at both ends of the circular arc surface 312. After the seesaw clamp 31 is rotatably connected to the second lock body 20, the decorative surfaces 313 are flush with the outer edges of the first and second bracelet bodies. The circular arc surface 312 that is flush with the outer edges of the first and second bracelet bodies effectively increases the user's operating area when pressing, improving user convenience. In addition, in the embodiment provided by the present invention, a pressing groove 3121 is provided on the circular arc surface 312 of the seesaw clamp 31, which effectively indicates the user's pressing position during the pressing operation, further improving the user's convenience and enhancing the user experience during use. In addition, through the arc surface 312 on the seesaw clamp 31 and the decorative surface 313 arranged on both sides of the arc surface 312, the overall concealment of the lock structure 100 using the bracelet can be effectively improved, effectively avoiding the exposure of the structure of the first lock body 10 and the second lock body 20, ensuring the fit between the arc surface 312 and the decorative surface 313 of the seesaw clamp 31 and the first bracelet body and the second bracelet body, and improving the overall aesthetics of the first bracelet body and the second bracelet body.

[0031] like Figure 3 As shown, the bottom of the U-shaped spring piece 32 abuts against the bottom of the arc surface 312 of the second lock body 20, causing the hook 311 of the rocker clip 31 to be snapped into the first slot of the first lock body 10 under the action of the elastic force. By abutting the bottom of the U-shaped spring piece 32 against the bottom of the arc surface 312 of the second lock body 20, the hook 311 of the rocker clip 31 is ensured to be snapped into the first slot of the first lock body 10 under the action of the elastic force and the action of the rotating latch 33. This effectively improves the accuracy with which the hook 311 of the rocker clip 31 is inserted into the first slot 11 of the first lock body 10, ensuring the stability of the rocker clip 31 and the first lock body 10 being snapped into place via the snap structure. Furthermore, when the user presses the arc surface 312 of the rocker latch 31, the rocker structure formed by rotating the latch 33 and the second lock body 20 can cause the hook 311 of the rocker latch 31 to disengage from the first latch hole 11 of the first lock body 10, thereby releasing the locked state between the rocker latch 31 and the first lock body 10.

[0032] like Figure 2 and Figure 4As shown, a first through hole 3131 is provided on the decorative surface 313, and a second through hole 211 is provided on the connecting portion 21 of the second lock body 20. The rotating latch 33 passes through the first through hole 3131 and into the second through hole 211, thereby rotatably connecting the rocker clip 31 to the second lock body 20. By providing the second through hole 211 on the second lock body 20 and using the rotating latch 33 to pass through the first through hole 3131 and into the second through hole 211, the rotating latch 33 can be effectively prevented from being installed on the bracelet body, further improving the overall concealment of the lock structure 100 using the bracelet, effectively preventing the structures of the first lock body 10 and the second lock body 20 from being exposed, ensuring the fit between the arc surface 312 and the decorative surface 313 of the rocker clip 31 and the first and second bracelet bodies, and improving the overall aesthetics of the first and second bracelet bodies.

[0033] like Figure 2 、 Figure 4 and Figure 5 As shown, in the embodiment provided by the present invention, the bottom of the first lock body 10 is a hollow structure and forms a guide groove 12 for the guide portion 22 of the second lock body 20 to penetrate. The guide portion 22 is provided with a second latch 221 for the hook 311 of the rocker clip 31 to engage. By inserting the guide portion 22 of the second lock body 20 into the guide groove 12 formed at the bottom of the first lock body 10, it can effectively play a guiding and positioning role. When the first lock body 10 and the second lock body 20 are locked and fixed using the snap structure, the first latch 11 on the first lock body 10 and the second latch 221 on the second lock body 20 are ensured to be connected. The hook 311 on the rocker clip 31 can pass through the second latch 221 on the second lock body 20 and engage with the first latch 11 on the first lock body 10, ensuring the effectiveness of the snap structure. While effectively improving the strength of the lock hook, it also reduces the overall thickness of the bracelet lock structure 100, thereby further improving the aesthetics.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
