Technical Field

[0001] This utility model relates to the field of ornament technology, specifically to a rotating heart-shaped clasp structure for ornaments. Background Technology

[0002] A rotating heart-shaped pendant changes its shape by rotating it.

[0003] Existing rotating heart-shaped clasp structures typically lack damping, causing the jewelry to rotate even under slight external force during wear, thus altering its shape. This results in an unstable shape achieved through rotation, affecting the wearing experience. To address this, we propose a rotating heart-shaped clasp structure for jewelry. Summary of the Invention

[0004] The purpose of this utility model is to provide a rotating heart-shaped clasp structure for jewelry, to solve the problem mentioned in the background art that existing rotating heart-shaped clasp structures generally lack damping effects, causing the jewelry to rotate even with slight external force during wear, thus changing its shape and making the shape obtained through rotation unstable, affecting the wearing effect. To achieve the above objective, this utility model provides the following technical solution: a rotating heart-shaped clasp structure for jewelry, comprising a first semi-elliptical body;

[0005] A rotating assembly includes a second semi-elliptic, the first and second semi-elliptic together forming an ellipse. The second and first semi-elliptic are formed by cutting through a tangent passing through the center of the ellipse. A rotating groove is formed on the tangent of the first semi-elliptic, and an annular groove is formed on the tangent of the first semi-elliptic, with the annular groove being concentric with the rotating groove. A retaining groove is formed on the inner wall of the annular groove. A movable groove is formed on the tangent of the second semi-elliptic, and a fixing groove is formed on the bottom inner wall of the movable groove. A limiting groove is formed on the inner annular surface of the movable groove.

[0006] A clamping assembly includes a fixing plate fixedly sleeved in a fixing groove. A rotating shaft is fixedly connected to one side of the fixing plate, and a protrusion is fixedly connected to the other end of the rotating shaft. The rotating shaft is rotatably connected in a rotating groove via a bearing. A rotating plate is movably sleeved on the side surface of the rotating shaft. A limit block is fixedly connected to the side surface of the rotating plate. A locking block is fixedly connected to one side of the rotating plate and is locked in a locking groove. A spring is movably connected to the side of the rotating plate opposite to the fixing plate and is movably sleeved on the rotating shaft.

[0007] More preferably, a hanging ring is fixedly connected to the side surface of the first semi-elliptic, and a hollow ring is hung on the top of the hanging ring.

[0008] More preferably, a fixing buckle is fixedly connected to the side surface of the hollow ring, a protruding rod is fixedly connected to the side surface of the hollow ring, and a ball is fixedly connected to the end of the protruding rod.

[0009] In a further preferred embodiment, the other end of the fixed buckle is hinged to a movable buckle, and the movable buckle has a through groove inside, through which the ball passes to form a snap-fit.

[0010] More preferably, the depth of the movable groove is greater than the thickness of the rotating piece, and the limiting groove is used to limit the rotation of the rotating piece by a limiting block.

[0011] More preferably, the locking block is hemispherical, the locking block is adapted to the locking slot, and the spring is used to provide a clamping force on the rotating plate.

[0012] More preferably, after the second semi-elliptic is rotated 180 degrees along the central axis of the rotation, it forms a heart shape with the first semi-elliptic.

[0013] More preferably, the protrusion is limited by the bearing and can only rotate along the central axis of the shaft and cannot slide along the extension direction of the shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the spring force pushes the locking block on the rotating plate, so that the locking block can be locked in the slot to form damping. This prevents the shape of the first and second semi-ellipsoids from changing when the second semi-ellipsoid is subjected to a slight external force, making the shape composed of the first and second semi-ellipsoids more stable and reducing the influence of external factors.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a rotating heart-shaped clasp structure for jewelry, including a first semi-elliptical body 1;

[0025] Rotating component 2 includes a second semi-elliptic 204, a first semi-elliptic 1, and a second semi-elliptic 204 together forming an ellipse. The second semi-elliptic 204 and the first semi-elliptic 1 are formed by cutting through a tangent passing through the center of the ellipse. A rotating groove 201 is provided on the tangent surface of the first semi-elliptic 1. An annular groove 202 is provided on the tangent surface of the first semi-elliptic 1 and is concentric with the rotating groove 201. A retaining groove 203 is provided on the inner wall of the annular groove 202. A movable groove 205 is provided on the tangent surface of the second semi-elliptic 204. A fixing groove 207 is provided on the bottom inner wall of the movable groove 205. A limiting groove 206 is provided on the inner annular surface of the movable groove 205.

[0026] The clamping assembly 3 includes a fixing plate 301, which is fixedly sleeved in a fixing groove 207. A rotating shaft 302 is fixedly connected to one side of the fixing plate 301, and a protrusion 303 is fixedly connected to the other end of the rotating shaft 302. The rotating shaft 302 is rotatably connected to the rotating groove 201 via a bearing. A rotating piece 307 is movably sleeved on the side surface of the rotating shaft 302. A limit block 305 is fixedly connected to the side surface of the rotating piece 307. A locking block 306 is fixedly connected to one side of the rotating piece 307 and engages in a locking groove 203. A spring 304 is movably connected to the side of the rotating piece 307 opposite to the fixing plate 301, and the spring 304 is movably sleeved on the rotating shaft 302. In use, rotating the second semi-ellipse... The second semi-elliptic 204 rotates, causing the rotating shaft 302 to rotate as well. As the second semi-elliptic 204 rotates, the limiting block 305, which is limited by the limiting groove 206, also rotates. At the same time, the rotating piece 307 and the locking block 306 rotate together. When the locking block 306 rotates, it gradually separates from the locking groove 203 and moves towards the fixing piece 301 against the force of the spring 304, thereby releasing the locking state and allowing the locking block 306 to slide into the annular groove 202. When the second semi-elliptic 204 rotates 180 degrees, the rotating piece 307 and the locking block 306, under the force of the spring 304, cause the locking block 306 to lock into the locking groove 203 again, so that the second semi-elliptic 204 and the first semi-elliptic 1 together form a heart shape.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a hanging ring 4 is fixedly connected to the side surface of the first semi-elliptic 1. A hollow ring 5 is hung on the top of the hanging ring 4. A fixing buckle 6 is fixedly connected to the side surface of the hollow ring 5. A protruding rod 8 is fixedly connected to the side surface of the hollow ring 5. A ball 9 is fixedly connected to the end of the protruding rod 8. By passing the ball 9 through the through groove 10, the ball 9 squeezes the inner wall of the through groove 10, forcing the through groove 10 on the movable buckle 7 to elastically deform. When the ball 9 has completely passed through the through groove 10, the movable buckle 7 returns to its original position through the elastic deformation force, thereby forming a snap-fit ​​between the movable buckle 7 and the fixing buckle 6. The other end of the fixing buckle 6 is hinged to the movable buckle 7. The movable buckle 7 has a through groove 10 inside, and the ball 9 passes through the through groove 10 to form a snap-fit.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the depth of the movable groove 205 is greater than the thickness of the rotating plate 307, and the limiting groove 206 is used to limit the rotating plate 307 by the limiting block 305 when it rotates.

[0029] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the locking block 306 is hemispherical and is adapted to the locking slot 203. The spring 304 is used to provide a clamping force on the rotating plate 307.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, after the second semi-elliptic 204 rotates 180 degrees along the central axis of the rotation axis 302, it forms a heart shape with the first semi-elliptic 1.

[0031] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the protruding post 303 can only rotate along the central axis of the rotating shaft 302 and cannot slide along the extension direction of the rotating shaft 302 due to the bearing limit.

[0032] The usage and advantages of this utility model: The rotating heart-shaped clasp structure of this ornament operates as follows:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, during use, rotating the second semi-elliptic 204 causes the rotating shaft 302 to rotate as well. Due to the rotation of the second semi-elliptic 204, the limiting block 305, which is limited by the limiting groove 206, also rotates. At the same time, the rotating piece 307 and the locking block 306 rotate together. When the locking block 306 rotates, it gradually separates from the locking groove 203 and moves towards the fixing piece 301 against the force of the spring 304, thereby releasing the locking state and allowing the locking block 306 to slide into the annular groove 202. When the second semi-elliptic 204 rotates 180 degrees, the rotating piece 307 and the locking block 306, under the force of the spring 304, cause the locking block 306 to lock into the locking groove 203 again, so that the second semi-elliptic 204 and the first semi-elliptic 1 together form a heart shape.

[0034] By passing the ball 9 through the through groove 10, the ball 9 presses against the inner wall of the through groove 10, forcing the through groove 10 on the movable buckle 7 to elastically deform. When the ball 9 has completely passed through the through groove 10, the movable buckle 7 recovers through the elastic deformation force, thereby making the movable buckle 7 and the fixed buckle 6 snap together.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
