Detailed Implementation

[0021] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0022] refer to Figures 1 to 5

[0023] A brooch that can be converted into a ring includes a decorative piece 10 and a ring 20 with a notch at the top. The ring has a first positioning groove 21 and a second positioning groove 22 on both sides of the notch. A connecting tube 30 is fixed to the rear side of the decorative piece. One end of the connecting tube is rotatably connected to the first positioning groove, and the other end of the connecting tube is fixed to a pin 32 by a spring 31. The pin is elastically extendable and has rotational elastic force. The pin is engaged with the second positioning groove for positioning. A limiting structure is provided between the connecting tube and the ring to enable the decorative piece to be positioned after being rotated upwards by 90°.

[0024] In this embodiment, one end of the connecting cylinder is provided with an outwardly protruding cylindrical protrusion 301, which extends into the first positioning groove and rotates with the first positioning groove.

[0025] In this embodiment, one end of the spring is fixed to the inner wall of one end of the connecting cylinder, and the other end of the spring is fixed to one end of the ejector pin. The other end of the ejector pin extends out of the connecting cylinder so as to engage with the second fixed groove for positioning.

[0026] In this embodiment, the other end of the ejector pin has a waist-shaped protrusion 321, and the second positioning groove is a waist-shaped hole whose shape matches the waist-shaped protrusion, so that the ejector pin can be engaged with the second positioning groove to prevent the ejector pin from rotating.

[0027] In this embodiment, the limiting structure includes a positioning protrusion 23 disposed on the ring and located on the other side of the notch. The other end of the connecting tube is provided with a first groove 302 that cooperates with the positioning protrusion, so that the ring and the decorative piece are in a brooch state in the initial state. The connecting tube is also provided with a second groove 303 for the decorative piece to rotate 90° along the circumference with the connecting tube and cooperate with the positioning protrusion, so that when the positioning protrusion cooperates with the second groove, the ring and the decorative piece are joined together to form a ring state.

[0028] In this embodiment, the side of the first groove near the second groove is a first inclined surface 304, and the side of the positioning protrusion near the first inclined surface of the first groove is a second inclined surface. Thus, when the ring is grasped and the decorative piece is flipped upwards by 90°, the positioning protrusion can better disengage from the first groove and then enter the second groove.

[0029] In this embodiment, the positioning protrusion protrudes towards the connecting cylinder so as to be embedded in the first groove or the second groove.

[0030] In this embodiment, the size of the first groove is slightly larger than that of the positioning protrusion, leaving a certain amount of room for the lower part of the ring to swing forward; and the similar length of the first groove and the second groove is greater than the lateral length of the positioning protrusion, which facilitates the axial movement of the connecting cylinder during installation and disassembly.

[0031] In this embodiment, the connecting cylinder, spring, and ejector pin are all metal parts.

[0032] Principle: The device initially functions as a brooch. When the connecting tube connects to the ring, after the pin is engaged and positioned in the second positioning groove, the connecting tube rotates a certain angle around its circumference. Then, one end of the connecting tube is inserted into the first positioning groove. Due to the spring's torque to restore its initial state, the lower part of the ring experiences a forward-rotating torque, creating a clamping force between the ring and the brooch. When the brooch is worn, the gap between the ring and the decorative piece, combined with the circumferential torque of the spring, allows the brooch to be clipped onto clothing.

[0033] Converting to a ring: Since one end of the connecting tube is rotatably connected to the first positioning groove, the ejector pin is fixed to the connecting tube by a spring, and the ejector pin is engaged with the second positioning groove. The decorative piece flips upward 90°, and the positioning protrusion is inserted into the second groove, turning the brooch into a ring. Converting a ring to a brooch: Move the connecting tube towards the ejector pin side (…). Figure 3 (Right side), the connecting protrusion at the left end of the connecting cylinder disengages from and is offset from the first positioning groove. Loosen the connecting cylinder, and under the action of the spring, the positioning protrusion disengages from the second groove (since the spring is fixed to the connecting cylinder, there is no need to worry about the spring disengaging from the connecting cylinder). Then rotate the connecting cylinder in the circumferential direction to make the first groove fit into the positioning protrusion. Finally, insert the cylindrical protrusion at one end of the connecting cylinder into the first positioning groove to form a brooch.

[0034] If the terms "first" and "second" are used in the above description to define the components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of distinguishing the components in the description. Unless otherwise stated, the above terms have no special meaning.

[0035] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0036] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0037] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0038] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
