[0020] 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. Example

[0021] Please see Figures 1-3This utility model provides the following technical solution: a pin-type replaceable connection structure, including a connecting pin 1 and a connecting sleeve 2 that fits into the connecting pin 1. The other end of the connecting sleeve 2 is also connected to an adjusting sleeve 4. A locking block 11 is formed on the side of the connecting pin 1. A mating groove 22, a rotating groove 23, and a locking groove 24 are formed in the connecting sleeve 2 to fit into the locking block 11. A recessed groove 21 is also formed in the connecting sleeve 2. A rubber block 3 is provided in the recessed groove 21 to abut against the support block 12 at the bottom of the connecting pin 1, thereby locking the locking block 11 in the locking groove 24, thereby connecting the connecting pin 1, the connecting sleeve 2, the adjusting sleeve 4 and the ornament 5. In this embodiment, through the design of the locking groove and the locking block, and with the help of the rubber block, the ornament can be quickly disassembled and replaced by simply pressing and rotating. The operation is simple and the connection is reliable.

[0022] Specifically, the ornament 5 has a through connecting hole 51, and both ends of the connecting hole 51 are formed with pressing grooves 52 with a diameter larger than the connecting hole 51. The upper end of the connecting pin 1 is formed with a first cap 13 that cooperates with the pressing groove 52 at one end. The bottom of the adjusting sleeve 4 is formed with a second cap 42 that cooperates with the pressing groove 52 at the other end. In this embodiment, the pressing groove 52 is inclined. The contact parts of the two caps and the first cap 13 are made of rubber. When the locking block 11 enters the rotating groove 23, it is squeezed and deformed with the cap. After the locking block 11 is inserted into the locking groove 24, it provides a certain amount of rebound movement distance, thereby ensuring a tight connection.

[0023] Furthermore, the first cap 13 has a first connecting ear 14 formed on its exterior, and the second cap 42 has a second connecting ear 43 formed on its exterior. The two connecting ears are used to connect with both ends of the chain, thereby forming a quick replacement between the chain and the ornament 5.

[0024] Specifically, the end of the connecting sleeve 2 away from the connecting pin 1 is formed with a threaded post 25, and the adjusting sleeve 4 is formed with an internal threaded groove 41 that is screwed into the threaded post 25. In this embodiment, the adjusting structure of the connecting sleeve 2 and the adjusting sleeve 4 allows it to adapt to jewelry 5 of different sizes and models, thus improving the flexibility and adaptability of use.

[0025] Furthermore, during the rotation of the locking block 11 in the rotating groove 23, the connecting sleeve 2 transmits pressure to the adjusting sleeve 4, thereby increasing the friction between the threaded post 25 and the internal thread groove 41. At this time, although the friction between the bottom of the support block 12 and the top of the rubber block 3 will also increase, due to the small contact area and its location at the axial center, the locking block 11 will not drive the threaded post 25 and the internal thread groove 41 to spiral when rotating in the rotating groove 23.

[0026] Specifically, the connecting pin 1 is inserted into the recess 21. When the connecting pin 1 is inserted into the recess 21, it can ensure the axial engagement of the locking block 11 and the mating groove 22, the circumferential rotation of the locking block 11 and the rotating groove 23, and finally stabilize in the locking groove 24.

[0027] Specifically, the mating groove 22 is axially inserted into the locking block 11, the rotating groove 23 is rotatably engaged with the locking block 11, and the locking groove 24 is located away from the rotating groove 23 and close to the sink groove 21. By arranging the sink groove 21 and the locking groove 24 at both ends of the rotating groove 23, the rotating groove 23 has a certain rotational stroke. Even if the locking block 11 is disengaged from the locking groove 24 under the action of external force, it will not easily enter the sink groove 21 through the rotating groove 23, thus ensuring a reliable connection.

[0028] The working principle and usage process of this utility model: The overall disassembled state is as follows... Figure 3 As shown, in actual use, the first connecting ear 14 and the second connecting ear 43 are connected to both ends of the chain, and the threaded post 25 and the internal thread groove 41 are in a spiral connection state.

[0029] The connecting sleeve 2 is inserted into the connecting hole 51 from one end of the ornament 5. The second cap 42 abuts against the pressing groove 52. The connecting pin 1 is inserted into the connecting hole 51 from the other end of the ornament 5. The locking block 11 slides down along the mating groove 22 and enters the rotating groove 23. During this process, the support block 12 and the rubber block 3 are pressed and contacted to form a rebound force. The locking block 11 is rotated by the connecting pin 1 so that the locking block 11 is located at the bottom of the locking groove 24. After the connecting pin 1 is released, the locking block 11 is locked in the locking groove 24 under the action of the rubber block 3, thus forming a lock.

[0030] When the length of the connecting hole 51 of the ornament 5 changes, the position of the adjusting sleeve 4 and the connecting sleeve 2 can be adjusted by the screw of the internal thread groove 41 and the threaded post 25, so as to adapt to the connection of ornaments 5 of different sizes.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
