[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] See also Figure 1-5, a jewelry lock structure 100 provided by the utility model, the jewelry lock structure 100 includes a first lock body 10, a second lock body 20, a double rocker assembly 30 arranged in the second lock body 20, and a key 40 for inserting into the double rocker assembly 30 to detach the first lock body 10 from the second lock body 20; the first lock body 10 and the second lock body 20 can be provided with jewelry of different shapes, the double rocker assembly 30 includes a first rocker clamp 31 and a second rocker clamp 32 that are rotatably connected, and a U-shaped spring piece 33 for elastically connecting the first rocker clamp 31 and the second rocker clamp 32, and the ends of the first rocker clamp 31 and the second rocker clamp 32 are provided with a locking structure for locking the first lock body 10 on the second lock body 20. The jewelry lock structure 100 provided by the present invention locks the first lock body 10 and the second lock body 20 by utilizing the locking structure of the first seesaw clamp 31 and the second seesaw clamp 32, and utilizes the U-shaped spring piece 33 to provide elastic force for the first seesaw clamp 31 and the second seesaw clamp 32. 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 jewelry lock buckle caused by materials such as gold, silver, copper, and tin, ensuring the rebound force, and avoiding the economic loss of the user caused by the jewelry falling off the lock due to insufficient locking force; in addition, the unlocking operation can be achieved by inserting the key 40 into the locking assembly of the second lock body 20, which can effectively improve the convenience of user operation and enhance the user experience during use.

[0028] like Figure 2 and Figure 3As shown, the elastic member is a U-shaped spring piece 33, which is embedded between the first rocker clip 31 and the second rocker clip 32. The first rocker clip 31 includes a first accommodating portion 311 for accommodating the U-shaped spring piece 33, a first rotating portion 312 for rotationally connecting to the second rocker clip 32, and a first abutting portion 313 for abutting the end of the key 40. The second rocker clip 32 includes a second accommodating portion 321 for accommodating the U-shaped spring piece 33, a second rotating portion 322 for rotationally connecting to the second rocker clip 32, and a second abutting portion 323 for abutting the end of the key 40. A mounting space for the U-shaped spring piece 33 is formed between the first accommodating portion 311 and the second accommodating portion 321, and an unlocking space for inserting the end of the key 40 is formed between the first abutting portion 313 and the second abutting portion 323. By embedding the U-shaped spring piece 33 in the installation space formed between the first accommodating portion 311 and the second accommodating portion 321 of the first rocker clip 31 and the second rocker clip 32, the stability of the U-shaped spring piece 33 embedded between the first rocker clip 31 and the second rocker clip 32 can be effectively improved, thereby effectively ensuring the stability of the elastic connection between the first rocker clip 31 and the second rocker clip 32, and then ensuring that after the front end of the key 40 is inserted into the unlocking space formed between the first abutting portion 313 and the second abutting portion 323, the first rocker clip 31 and the second rocker clip 32 form a seesaw structure under the action of the U-shaped spring piece 33, and release the locking state between the first lock body 10 and the second lock body 20, thereby realizing the operation of disengaging the first lock body 10 from the second lock body 20.

[0029] like Figure 2 and Figure 5 As shown, the front end of the second lock body 20 is provided with an unlocking hole 21, and the end of the key 40 is inserted through the unlocking hole 21 and into the unlocking space. By inserting the end of the key 40 through the unlocking hole 21 and into the unlocking space, the displacement of the key 40 within the unlocking space can be effectively limited, ensuring the accuracy of the insertion of the front end of the key 40 into the unlocking space formed between the first abutting portion 313 and the second abutting portion 323. This ensures that by inserting the front end of the key 40 into the double rocker assembly 30, the locked state between the first lock body 10 and the second lock body 20 can be released, and the first lock body 10 can be disengaged from the second lock body 20. The second lock body 20 is provided with a first rotation hole, and the first rotation portion 312 and the second rotation portion 322 are respectively provided with a second rotation hole and a third rotation hole. The rotating shaft 50 passes through the first rotation hole of the second lock body 20 and is inserted into the second rotation hole and the third rotation hole, thereby rotatably connecting the first rocker clamp 31 and the second rocker clamp 32. By passing the rotating shaft 50 through the first rotating hole on the second lock body 20 and inserting it into the second rotating hole and the third rotating hole, the smoothness of the rotating connection between the first rocker clamp 31 and the second rocker clamp 32 can be effectively ensured.

[0030] like Figure 2 and Figure 3 As shown, the locking structure comprises a first locking hook 314 and a second locking hook 324 provided on the first rocker clip 31 and the second rocker clip 32, and a limiting platform 11 is provided on the first lock body 10 for locking and fixing with the first locking hook 314 and the second locking hook 324. By locking and fixing the first locking hook 314 and the second locking hook 324 on the first rocker clip 31 and the second rocker clip 32 with the limiting platform 11 on the first lock body 10, the stability of the locking and fixing between the first lock body 10 and the second lock body 20 in the original state can be effectively guaranteed, effectively preventing the first lock body 10 from falling off the second lock body 20 during use, thereby avoiding economic losses to the user. In the embodiment provided by the present invention, a limiting plate 22 is further provided in the second lock body 20. When the end of the key 40 is inserted into the double rocker assembly 30, the end surfaces of the first and second lock hooks 314, 324 abut against the limiting plate 22, thereby releasing the locked state between the first and second lock hooks 314, 324 and the limiting platform 11 on the first lock body 10. The limiting plate 22 effectively limits the insertion of the end of the key 40 into the double rocker assembly 30, preventing the end surfaces of the first and second lock hooks 314, 324 from directly abutting each other and causing wear.

[0031] like Figure 1 and Figure 4 As shown, a limiting boss 41 is provided on the key 40. The limiting boss 41 abuts against the end surface of the unlocking hole 21 to limit the displacement of the key 40 when inserted into the unlocking space. The limiting boss 41 effectively limits the displacement of the key 40 when inserted into the unlocking space, thereby ensuring that the end of the key 40 is inserted into the double rocker assembly 30, so that the end surfaces of the first lock hook 314 and the second lock hook 324 abut against the limiting plate 22, and that the displacement of the key 40 when inserted into the unlocking space is too large, resulting in wear between the end of the key 40 and the inner surfaces of the first rocker clamp 31 and the second rocker clamp 32.

[0032] 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.
