DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with specific drawings.

[0030] See also Figure 1 The utility model provides a piece of jewelry, including a jewelry body 100 and a buckle structure, wherein the jewelry body 100 includes a first jewelry body 110 with an opening and a second jewelry body 120. The first end of the second jewelry body 120 is hinged to the first end of the first jewelry body 110 to achieve the opening and closing of the first jewelry body 110 and the second jewelry body 120. The second jewelry body 120 is clamped with the second end of the first jewelry body 110 through the buckle structure to fix the first jewelry body 110 and the second jewelry body 120 in the circumferential and radial directions of the jewelry body 100. Please refer to Figure 3 The first jewelry body 110 and the second jewelry body 120 of the split jewelry are connected by the buckle structure to form a ring structure (such as a circular ring, an elliptical ring, a polygonal ring, etc.). Both ends of the first jewelry body 110 and the second jewelry body 120 can be connected by the buckle structure.

[0031] The buckle structure includes a circumferential clamping assembly for limiting the second jewelry body 120 circumferentially to the first jewelry body 110 and a radial limiting assembly for limiting the second jewelry body 120 radially to the first jewelry body 110. The circumferential clamping assembly includes a first clamping portion provided at the end of the first jewelry body 110 and a second clamping portion provided at the end of the second jewelry body 120 and engaged with the first clamping portion. The radial limiting assembly can limit the first clamping portion and the second clamping portion in the radial direction to prevent the first jewelry body 110 and the second jewelry body 120 from separating in the radial direction. When the opening position of the split jewelry is fixed circumferentially and radially, it can ensure that the first jewelry body 110 and the second jewelry body 120 maintain a stable shape and structure when subjected to various tensions or pressures, thereby improving the stability of the jewelry, preventing it from being pulled apart and accidentally opened, and reducing the risk of the jewelry falling.

[0032] Specifically, the second end of the first jewelry body 110 is also provided with a recessed groove 200 recessed inward from the outer surface of the first jewelry body 110, and the clip 210 is formed by being recessed inward from the bottom surface of the recessed groove 200 in the radial direction. The second end of the second jewelry body 120 is formed with a convex portion 300 adapted to the recessed groove 200, and the clip block 310 is provided on the inner surface of the convex portion 300 at a position corresponding to the clip 210; when the convex portion 300 is assembled in the recessed groove 200 and the clip block 310 is clipped into the clip 210, the outer surface of the convex portion 300 smoothly transitions with both the first jewelry body 110 and the second jewelry body 120. After the clamping block 310 is clamped in the clamping port 210, the first jewelry body 110 and the second jewelry body 120 can be circumferentially limited. After being limited, the connection between the first jewelry body 110 and the second jewelry body 120 can have a smooth transition, thereby improving the aesthetics of the jewelry.

[0033] It should be understood that the arrangement of the recessed groove 200 and the convex portion 300 can also have other adaptive changes. For example, in one embodiment, the second end of the first jewelry body 110 is provided with a recessed groove 200 that is recessed outward from the inner surface of the first jewelry body 110, and the bayonet 210 is formed from the bottom surface of the recessed groove 200 and is recessed outward in the radial direction. The second end of the second jewelry body 120 is formed with a convex portion 300 that matches the recessed groove 200, and the clamping block 310 is arranged on the outer surface of the convex portion 300 at a position corresponding to the bayonet 210. When the convex portion 300 is assembled in the recessed groove 200 and the clamping block 310 is clamped in the bayonet 210, the inner surface of the convex portion 300 is smoothly transitioned with the first jewelry body 110 and the second jewelry body 120. The smooth transition of the inner surface of the jewelry body 100 helps to improve the wearing comfort.

[0034] In another embodiment, the second end of the second jewelry body 120 is provided with a recessed groove 200 recessed inward from the outer surface of the second jewelry body 120, and the clip 210 is recessed inward from the bottom surface of the recessed groove 200 in the radial direction. The second end of the first jewelry body 110 is formed with a convex portion 300 adapted to the recessed groove 200, and the clip block 310 is provided on the inner surface of the convex portion 300 at a position corresponding to the clip 210. When the convex portion 300 is assembled in the recessed groove 200 and the clip block 310 is clipped into the clip 210, the outer surface of the convex portion 300 smoothly transitions with both the first jewelry body 110 and the second jewelry body 120.

[0035] In another embodiment, the second end of the second jewelry body 120 is provided with a recessed groove 200 recessed outward from the inner surface of the second jewelry body 120, and the clip 210 is recessed outward from the groove bottom surface of the recessed groove 200 in the radial direction. The second end of the first jewelry body 110 is formed with a convex portion 300 adapted to the recessed groove 200, and the clip block 310 is provided on the outer surface of the convex portion 300 at a position corresponding to the clip 210. When the convex portion 300 is assembled in the recessed groove 200 and the clip block 310 is clipped into the clip 210, the inner surface of the convex portion 300 smoothly transitions with the first jewelry body 110 and the second jewelry body 120.

[0036] The bottom surface of the recessed groove 200 is embedded with a first magnetic block 220, see Figure 2 A second magnetic block 320 that can be attracted to the first magnetic block is disposed at a corresponding position of the protruding portion 300. When the block 310 is inserted into the bayonet 210, the first magnetic block 220 and the second magnetic block 320 are attracted to each other, further strengthening the stability of the connection to prevent shaking of the connection.

[0037] The radial limiting assembly includes a limiting groove 410 disposed on one end of the clamping protrusion 300 near the clamping port 210, and the limiting groove 410 passes through one end surface of the clamping protrusion 300 near the clamping port 210 in the circumferential direction. The radial limiting assembly also includes a movable limiting member 420 disposed near the clamping port 210 and capable of extending into the clamping port 210 in the circumferential direction. When the clamping protrusion 300 is assembled in the recessed groove 200 and the clamping block 310 is clamped into the clamping port 210, the movable limiting member 420 can extend into the limiting groove 410 to prevent the first jewelry body 110 and the second jewelry body 120 from separating in the radial direction. The circumferential and radial limiting of the opening position of the split jewelry body 100 is completed, the connection strength of the clamping joint is improved, and the wear and deformation caused by frequent opening and closing are reduced, thereby extending the service life of the jewelry.

[0038] In this embodiment, the recessed groove 200 and the bayonet 210 are both disposed at the second end of the first jewelry body 110, and a mounting cavity 400A is disposed at a position of the first jewelry body 110 near the bayonet 210. The inner surface of the first jewelry body 110 is provided with a through hole communicating with the mounting cavity 400A, and a sealing sheet 111 is welded at the through hole position to seal the through hole. After the through hole is sealed, the sealing sheet surface 111 and the first jewelry body 110 are smoothly transitioned, giving the wearer a more comfortable experience. It should be understood that in other embodiments, when the recessed groove 200 and the bayonet 210 are disposed at the second end of the second jewelry body 120, the mounting cavity 400A is adaptively disposed at a corresponding position on the second jewelry body 120.

[0039] The installation cavity 400A is disposed on a side of the bayonet 210 away from the bayonet protrusion 300, and the installation cavity 400A is connected to the bayonet 210 along the circumferential direction to form a first through-opening for the movable stopper 420 to pass through. The installation cavity 400A is formed to have a second through-opening 400B through the axial direction of the jewelry body 100, and the length of the second through-opening 400B is distributed along the circumferential direction of the jewelry body 100. The movable stopper 420 comprises a main body 421 movably disposed in the installation cavity 400A, a stopper 422 connected to the main body 421 and capable of movably passing through the first through-opening, and an adjustment portion 423 connected to the main body 421 and movably passing through the second through-opening 400B to be exposed outside the jewelry body 100. The main body 421 is provided with a through hole 4210 which can penetrate the main body 421. On the one hand, it can reduce the dead weight of the movable limiting component 420. On the other hand, after the through hole 4210 is provided, it is convenient to use tweezers or other objects to reach into the through hole 4210 to clamp the movable limiting component 420, so that the smaller movable limiting component 420 can be assembled in the installation cavity 400A.

[0040] When the first jewelry body 110 and the second jewelry body 120 are engaged, the position of the movable limiting member 420 can be flexibly adjusted by holding the adjusting portion 423. The limiting portion 422 is first manipulated to move in the direction of the mounting cavity 400A to avoid the block 310, so that the block 310 can be smoothly inserted into the bayonet 210. The movable limiting member 420 is manipulated to move so that the limiting portion 422 is engaged with the limiting groove 410 to complete radial fixation.

[0041] The radial limiting assembly further includes a force applying unit 430 disposed in the installation cavity 400A and capable of applying a force along the circumferential direction toward the limiting groove 410 to the movable limiting member 420. When the limiting portion 422 moves in the direction of going deeper into the installation cavity 400A and the clamping block 310 enters the clamping port 210, the force applying unit 430 applies a thrust to the movable limiting member 420 to push the movable limiting member 420 to move, so that the limiting portion 422 is inserted into the limiting groove 410 to achieve radial fixation.

[0042] See also Figure 4 The force applying unit 430 includes a third magnetic block 431 disposed on the movable stopper 420 and away from one end of the stopper 422, and a fourth magnetic block 432 disposed in the mounting cavity 400A and corresponding to the third magnetic block 431. The third magnetic block 431 and the fourth magnetic block 432 have the same polarity at opposite ends. The two opposite magnetic blocks have the same polarity at opposite ends, and use repulsion to drive the movable stopper 420 to move.

[0043] In another embodiment, the force applying unit 430 is defined as an elastic member abutting between an end of the main body 421 away from the limiting portion 422 and a corresponding side wall of the installation cavity 400A. Figure 5-Figure 7 The elastic member is limited to a coil spring 433, a torsion spring 434 or a spring leaf 435. Please continue to refer to Figure 5 When the elastic member is configured as a coil spring 433, a side cavity 400C may be configured on the side of the installation cavity 400A away from the limiting portion 422, and the side cavity 400C is connected to the installation cavity 400A along the circumferential direction. One end of the coil spring 433 extends into the side cavity 400C to abut against it, and the other end extends into the installation cavity 400A to abut against the movable limiting member 420.

[0044] When the open end of the jewelry body 100 is engaged, the convex portion enters the recessed groove 200. After the block 310 is engaged in the bayonet 210, the block 310 applies force to the limiting portion 422 to cause the limiting portion 422 to move toward the direction of the deep installation cavity 400A to avoid the block 310 from completing the engagement. Then the elastic member or the third magnetic block 431 and the fourth magnetic block 432 cooperate with each other to apply thrust to the movable limiting member 420 to cause the limiting portion 422 to be engaged in the limiting groove 410. The entire engaging process is completed by the block 310 set on the convex portion 300 squeezing the limiting portion 422 in the bayonet 210. The engaging process is simple and convenient, and the jewelry can be engaged and locked with one hand. When the split jewelry needs to be opened, the adjusting portion 423 is held and moved away from the engaging position. After the limiting groove 410 is separated from the limiting portion 422 , the clamping port 210 can be smoothly controlled to separate from the clamping block 310 .

[0045] The jewelry: 1. When the split jewelry body 100 is clamped at the opening position, the clamping block 310 is clamped into the clamping port 210 to complete the circumferential fixation of the opening end of the jewelry product, and the limiting portion 422 is inserted into the limiting groove 410 to complete the radial fixation of the jewelry product. After the split jewelry body 100 is fixed circumferentially and radially, the jewelry product is not easy to fall off when worn, because the radial and circumferential fixation ensures the stability of the jewelry and reduces the risk of the jewelry product falling due to looseness. Moreover, such a buckle structure further enhances the stability and bearing capacity of the clamping position, thereby improving its overall stability and reliability, and enabling the clamping position of the jewelry product to withstand greater tension and pressure. 2. After the buckle structure completes the circumferential and radial locking of the jewelry, the outer surface of the clamping protrusion 300 has a smooth transition with the first jewelry body 110 and the second jewelry body 120, without an outward protrusion structure, thereby improving the aesthetics of the jewelry. 3. After the clamping block 310 is inserted into the clamping port 210, the first magnetic block 220 and the second magnetic block 320 are attracted to each other, thereby enhancing the stability of the clamping position and preventing the first jewelry body 110 and the second jewelry body 120 from shaking at the clamping position and affecting the use. 4. When the movable stopper 420 installed in the installation cavity 400A is engaged, the clamping block 310 presses the stopper 422 to move, and the clamping port 210 and the clamping block 310 are quickly connected. The squeezed movable stopper 420, under the cooperation of the third magnetic block 431 and the fourth magnetic block 432 or the action of the elastic member, the stopper 422 moves toward the stopper slot 410 and is engaged in the stopper slot 410. The engagement is simple, convenient and easy to operate.
