[0028] First embodiment

[0029] Please refer to Figure 1-3 According to one aspect of the present invention, there is provided a jewelry connecting device 100 for connecting a first piece of jewelry 10a and a second piece of jewelry 10b, comprising a first connecting seat 10, a second connecting seat 20 and a clamping assembly 30. The first connecting seat 10 is used to connect the first piece of jewelry 10a, and the second connecting seat 20 is used to connect the second piece of jewelry 10b. The first connecting seat 10 is provided with a through hole 11, and the second connecting seat 20 is provided with a clamping position 21. The first connecting seat 10 is used to be mutually sleeved with the second connecting seat 20. The clamping assembly 30 is telescopically provided in the through hole 11, and when the first connecting seat 10 and the second connecting seat 20 are sleeved, the clamping assembly 30 is clamped with the clamping position 21, so as to fix the first connecting seat 10 and the second connecting seat 20 to connect the first piece of jewelry 10a and the second piece of jewelry 10b.

[0030] Specifically, the jewelry connecting device 100 can be used to connect two independent jewelry, or to connect the two ends of linear jewelry such as bracelets, bracelets, necklaces, etc. to form a closed ring. The first connecting seat 10 is sleeved outside the second connecting seat 20 to wrap the second connecting seat 20, or the second connecting seat 20 is sleeved outside the first connecting seat 10 to wrap the first connecting seat 10. The specific sleeve arrangement of the first connecting seat 10 and the second connecting seat 20 is determined according to the shape design of the two. This embodiment takes the connection form of the first connecting seat 10 sleeved outside the second connecting seat 20 as the basis for the following description.

[0031] The first connection seat 10 and the second connection seat 20 are respectively provided with a through hole 11 and a latch 21. It is worth noting that the through hole 11 is a through hole that passes through both sides of the first connection seat 10, and the latch 21 can be a through hole that passes through both sides of the second connection seat 20, or a latch groove located in the second connection seat 20. The two sides of the first connection seat 10 or the two sides of the second connection seat 20 can be understood as two sides that are not observable in the same plane, and are not limited to whether the two sides are symmetrical or opposite.

[0032] When the first connection seat 10 is sleeved in the second connection seat 20, the first connection seat 10 drives the clamping assembly 30 to fall into the clamping position 21 and clamp therewith. During the process, due to the action of the second connection seat 20, the clamping assembly 30 is forced to shrink and avoid the first connection seat 10 from sleeved into the first connection seat 10. When the clamping assembly 30 is aligned with the clamping position 21, the clamping assembly 30 is no longer restricted by the second connection seat 20 and stretches and enters the clamping position 21. The clamping assembly 30 connects the through hole 11 and the clamping position 21 together. The through hole 11 and the clamping position 21 are connected by the clamping assembly 30. 0 and the first connection seat 10 and the second connection seat 20 are limited so that the first connection seat 10 and the second connection seat 20 cannot move relative to each other. Since the clamping assembly 30 is fixed in the through hole 11 of the first connection seat 10, once the clamping assembly 30 and the clamping position 21 are clamped, the clamping assembly 30 cannot be easily withdrawn. Moreover, since the clamping position 21 on the second connection seat 20 may be a clamping groove or a small hole, the clamping assembly 30 may not be observed or touched from the appearance of the assembled jewelry, and it is even more difficult to withdraw it. In this way, the first connection seat 10 and the second connection seat 20 can be locked and cannot be unlocked reversibly.

[0033] In this embodiment, the second connecting seat 20 is provided with a accommodating space 22, and the accommodating space 22 is used to accommodate the first connecting seat 10, so that the second connecting seat 20 is sleeved outside the first connecting seat 10, and the clamping position 21 is connected to the accommodating space 22. When the first connecting seat 10 is sleeved in the accommodating space 22, the through hole 11 is aligned with the clamping position 21.

[0034] Specifically, the second connecting seat 20 can be an internally hollow structure, in which a accommodating space 22 for accommodating the second connecting seat 20 is formed. The latching position 21 is opened from the inner wall of the second connecting seat 20, and the opening of the latching position 21 is facing the accommodating space 22, ensuring that the latching position 21 is connected to the accommodating space 22, so that after the first connecting seat 10 enters the accommodating space 22, the snap-in assembly 30 can enter the latching position 21 from the accommodating space 22.

[0035] In this embodiment, the second connecting seat 20 is annular in structure and defines a accommodating space 22. The second connecting seat 20 is provided with an avoidance groove 23 connected to the accommodating space 22. When the first connecting seat 10 is sleeved in the accommodating space 22, the avoidance groove 23 is used to avoid the first connecting seat 10 from being connected to the first jewelry 10a of the jewelry.

[0036] Specifically, when the first connecting seat 10 is sleeved in the accommodating space 22, the annular second connecting seat 20 can wrap the entire circumference of the first connecting seat 10, thereby improving the sleeve stability of the first connecting seat 10 and the second connecting seat 20, and further reducing the probability of loosening of the snap-in assembly 30 and the through hole 11 and the snap position 21.

[0037] In other embodiments, the second connecting seat 20 may also be arc-shaped, semicircular, “[”-shaped, “<”-shaped, etc.

[0038] In this embodiment, a connecting member 40 is further included, and the connecting member 40 is used to connect the first connecting seat 10 and the first jewelry 10a. When the first connecting seat 10 and the second connecting seat 20 are locked with each other, the connecting member 40 is embedded in the avoidance groove 23 to avoid stacking of the connecting member 40 and the second connecting seat 20 due to the connection between the first connecting seat 10 and the second connecting seat 20, thereby ensuring the flatness of the entire jewelry.

[0039] In this embodiment, the snap-fit ​​assembly 30 includes a spring 31 and a snap-fit ​​block 32. The snap-fit ​​block 32 has a connecting portion 321 and a limiting portion 322. The connecting portion 321 is arranged in the through hole 11 and is hinged to the first connecting seat 10. The limiting portion 322 is used to insert into the snap-fit ​​position 21. As the connecting portion 321 rotates, the limiting portion 322 enters the snap-fit ​​position 21. The spring 31 is used to return the snap-fit ​​block 32 after rotation, thereby locking the first connecting seat 10 and the second connecting seat 20.

[0040] Specifically, the spring 31 can be a restoring spring, the connecting portion 321 can be hinged to the first connecting seat 10 through the spring 31, and the spring 31 can also be a common coil spring, the connecting portion 321 is hinged to the first connecting seat 10, and the connecting portion 321 and the first connecting seat 10 are connected by the spring 31; after the connecting portion 321 rotates, the limiting portion 322 is driven to rotate, and the spring 31 is also deformed accordingly, and the spring 31 always keeps pulling the connecting portion 321 due to the elastic deformation until the connecting portion 321 rotates back to the initial position or restores the initial state. However, the spring 31 will not deform autonomously, so after the connecting portion 321 returns to the initial position or restores the initial state, there is no external force acting on the connecting portion 321, so that the clamping portion 112 maintains the clamping state with the clamping position 21 without being damaged, and the irreversibility of the locking of the first connecting seat 10 and the second connecting seat 20 is achieved.

[0041] Please continue to refer to Figure 3 The limiting portion 322 may be disposed at one end of the connecting portion 321 , or may be disposed at the middle of the connecting portion 321 .

[0042] In this embodiment, two opposite sides of the second connection base 20 are provided with latching positions 21 . When the first connection base 10 is sleeved in the accommodating space 22 , the two latching positions 21 are latched with the latching assembly 30 .

[0043] Specifically, two opposite latching positions 21 are provided on the second connecting seat 20. When the latching assembly 30 is latched with the two latching positions 21, the connecting forces on both sides of the through hole 11 can be balanced, so that after the first connecting seat 10 and the second connecting seat 20 are connected, the force on the latching assembly 30 is more uniform, thus avoiding damage such as breakage of the latching assembly 30 due to a single connection point.

[0044] In this embodiment, there are two clamping blocks 32, and the two clamping blocks 32 are connected by a spring 31. The connecting parts 321 of the two clamping blocks 32 are respectively located at the two ends of the through hole 11, and are both hinged to the first connecting seat 10. As the two connecting parts 321 rotate, the two limiting parts 322 respectively enter the two clamping positions 21.

[0045] Specifically, the positions 21 on both sides of the through hole 11 are connected by the clamping blocks 32, and the spring 31 is connected between the two clamping blocks 32, so that the two clamping blocks 32 are squeezed and deformed before entering the position 21, thereby shortening the distance between the two clamping blocks 32, thereby avoiding the clamping blocks 32 from entering the position 21. After the limiting portion 322 completely enters the position 21 and completes the fixed connection with the position 21, since the clamping block 32 is no longer restricted or squeezed, the spring 31 is stretched and restored to its original state. The restoring force of the spring 31 pushes the two clamping blocks 32 back to the original distance, so that the limiting portion 322 cannot withdraw from the position 21, thereby ensuring the stability and irreversibility of the connection.

[0046] In this embodiment, the clamping assembly 30 further includes a connecting rod (not shown in the figure), which is sleeved in the spring 31 and fixed to the first connecting seat 10 .

[0047] Specifically, the connecting rod can limit the deformation direction of the spring 31 and has a supporting effect on the spring 31 .

[0048] In this embodiment, the through hole 11 has a middle part 111 and a clamping part 112 located at both ends of the middle part 111, the connecting part 321 is arranged on the clamping part 112, the spring 31 is arranged on the middle part 111, and a limit block 12 is provided on the side of the clamping part 112 away from the middle part 111, and the limit block 12 is used to limit the connecting part 321 from rotating out of the through hole 11.

[0049] Specifically, in terms of width, the middle portion 111 is preferably loosely fitted with the spring 31, so that the spring 31 can be compressed or stretched in the middle portion 111, and the middle portion 111 can limit the spring 31 and guide the deformation direction. The limit block 12 is arranged at the end of the through hole 11, which can limit the autonomous outward rotation of the snap block 32 to release the snap connection with the snap position 21.

[0050] In this embodiment, the limiting portion 322 has a guiding surface 3221 , the guiding surface 3221 is connected to the connecting portion 321 , and the guiding surface 3221 is inclined from the connecting portion 321 toward a direction close to the limiting block 12 .

[0051] Specifically, due to the limiting effect of the limit block 12, the rotation direction of the clamping block 32 is limited. When the guide surface 3221 tilts toward the limit block 12, the tilting direction is consistent with the rotation direction, so it has a guiding effect. Before the clamping block 32 enters the clamping position 21, the guide surface 3221 abuts against the outside of the clamping position 21, and the second connecting seat 20 interacts with the clamping block 32, so that the clamping block 32 rotates and continues to enter the clamping position 21. The inclined guide surface 3221 is conducive to guiding the limit portion 322 to enter the clamping position 21.

[0052] In this embodiment, the guide surface 3221 is an arc-shaped surface.

[0053] Specifically, the arc-shaped guide surface 3221 has a characteristic of gradually increasing inclination, so that the rotation speed of the limit portion 322 gradually increases as the inclination increases. When the clamping block 32 initially falls into the clamping position 21, the limit portion 322 still needs to find the clamping position 21 to determine a suitable clamping point. At this time, the limit portion 322 should rotate slowly. When the front part of the limit portion 322 has entered the clamping position 21, the rotation speed of the limit portion 322 should be accelerated to quickly complete the locking.

[0054] The jewelry connecting device 100 provided by the utility model is provided with a through hole 11 on the first connecting seat 10 to accommodate the clamping assembly 30, and a clamping position 21 is provided on the second connecting seat 20, so that when the first connecting seat 10 and the second connecting seat 20 are mutually sleeved, the clamping assembly 30 falls into the clamping position 21 to be mutually clamped and locked. Since the clamping assembly 30 and the first connecting seat 10 are fixed to each other, the clamping assembly 30 and the clamping position 21 cannot be withdrawn once locked, thereby preventing the jewelry from being subjected to uncontrollable force after connection and being automatically unlocked in reverse.

[0055] Second embodiment

[0056] Please refer to Figure 4 Another aspect of the present invention provides a bracelet, comprising a first piece of jewelry 10a, a second piece of jewelry 10b and at least one jewelry connecting device 100 as described in the first embodiment, preferably one jewelry connecting device 100, the first piece of jewelry 10a and the second piece of jewelry 10b are connected to form a closed loop through the jewelry connecting device 100.

[0057] In this embodiment, the bracelet also includes a lock 10c, which includes a first support 10c1 and a second support 10c2. The first support 10c1 is used to connect the first jewelry 10a, and the second support 10c2 is used to connect the second jewelry 10b. The first support 10c1 is threadedly connected to the second support 10c2 to connect the first jewelry 10a and the second jewelry 10b.

[0058] In this embodiment, the first jewelry 10a is in a tube shape, and the second jewelry 10b is in a chain shape, so that the bracelet forms a bracelet chain.

[0059] In other embodiments, the first jewelry 10a and the second jewelry 10b may both be in a chain shape or a tube shape, so that the bracelet forms a bracelet or a bangle.

[0060] Third embodiment

[0061] Please refer to Figure 5 Another embodiment of the present invention provides a bracelet, which is different from the second embodiment in that it includes a first piece of jewelry 10a, a second piece of jewelry 10b and two jewelry connecting devices 100, and the first piece of jewelry 10a and the second piece of jewelry 10b are connected to form a closed loop through the jewelry connecting devices 100.

[0062] In this embodiment, the first jewelry 10a is tubular, the second jewelry 10b is chain-shaped, and both ends of the first jewelry 10a and the second jewelry 10b are connected by a jewelry connecting device 100 to form a closed bracelet chain. Since the first jewelry 10a and the second jewelry 10b have different structures and different force points, they will not be easily unlocked when using the same connection structure.

[0063] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
