[0001] This utility model belongs to the technical field of brooch accessories, and in particular relates to a wheel-shaped brooch accessory. Background Technology
[0002] As a decorative and personalized accessory, the structural design of brooches directly affects the wearing experience and safety. Currently, most brooch accessories on the market are fastened by inserting pins into clothing.
[0003] First, the buckle tip of traditional brooches usually lacks an effective sealing structure. During wearing or storage, the sharp buckle tip can easily snag on clothing fibers, causing damage to the clothing and potentially scratching the user's skin, posing a significant safety hazard.
[0004] Secondly, the existing brooch accessories lack sufficient fastening stability. After wearing, they are easily loosened by external force, causing the brooch to slip off clothing, resulting in damage or loss of the jewelry. Utility Model Content
[0005] The technical problem this invention aims to solve is that the end of the brooch usually lacks an effective sealing structure, which poses a significant safety hazard during wearing or storage. The fastening stability of the brooch accessories is insufficient, and they are easily loosened by external force after wearing, causing the brooch to slip off clothing and resulting in damage or loss of the jewelry.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a wheel-shaped brooch accessory, including a U-shaped mounting block, wherein a buckle pin is rotatably connected between the inner walls of the mounting block, and further comprising...
[0007] A sealing assembly is located at the end of a buckle pin and includes a base block detachably connected to the end of the buckle pin. The base block is U-shaped, and buckles are fixedly connected to both sides of the top of the base block. The buckles are through-holes in the middle and have a notch on one side.
[0008] Furthermore, a limiting member is rotatably connected between the opposite sidewalls of the buckle. The limiting member is arranged in a circular shape, and one side of the limiting member is open.
[0009] Furthermore, the outer wall of the limiting member is fixedly connected with a correspondingly arranged lever, and the end of the buckle pin near the mounting block is fixedly connected to the limiting block.
[0010] Furthermore, the toggle block is made of metal, and the inner bottom wall of the base block is made of magnetic material.
[0011] The beneficial effects of this utility model after adopting the above structure are as follows:
[0012] (1) The U-shaped bottom block can be detachably connected to the end of the buckle, and together with the ring-shaped limiting piece at the opening of the buckle head, it can completely cover the sharp end of the buckle, replacing the traditional unsealed structure, avoiding snagging on clothes and scratching the skin when wearing or storing, and solving the safety hazard problem.
[0013] (2) The inner bottom wall of the base block is made of magnetic material, which can attract the metal pin to fix the limiting piece; the end of the pin forms a double fastening with the limiting piece through the base block, the pin head and the limiting piece, which replaces the single insertion and fixation, and avoids the brooch from loosening and slipping due to external force, and prevents the jewelry from being damaged or lost.
[0014] (3) The bottom block and the buckle pin are detachably connected, making it easy to replace or maintain; the lever can be easily rotated to open and close the limit piece, making it simple to operate and suitable for wearing clothes of different thicknesses, thus improving the flexibility of use.

[0019] like Figure 1-2 As shown, a wheel-shaped brooch accessory includes a U-shaped mounting block 1, which serves as the basic support structure for the brooch accessory and can be connected to the wheel-shaped brooch body. A buckle 2 is rotatably connected between the inner walls of the mounting block 1. The buckle 2 can rotate around the inner wall of the mounting block 1, providing a basis for subsequent insertion of clothing for wearing. The rotating design can adapt to different wearing angles and improve operational flexibility.
[0020] The end of the pin 2 is equipped with a sealing component, which is the core structure to ensure wearing safety and a secure fastening. This includes a base block 3 detachably connected to the end of the pin 2. The base block 3 is U-shaped and detachably connected to the pin 2. When the base block 3 is worn or needs to be replaced with a different style, there is no need to replace the entire part. Only the base block 3 needs to be removed for maintenance or replacement, reducing usage costs. At the same time, the base block 3 can be adapted to different materials according to the style of the brooch, improving the versatility of the parts. The top two sides of the base block 3 are fixedly connected to buckles 4. The buckles 4 are through-shaped in the middle and have a notch 5 on one side. A limiting member 6 is rotatably connected between the opposite side walls of the buckles 4. The limiting member 6 is circular and has an opening on one side. The limiting member 6 can rotate around the side wall of the buckle 4. Its opening design makes it easy to adjust the position after the pin 2 is inserted. The circular structure can wrap around the end of the pin 2, avoiding the safety hazards caused by the lack of a sealing at the end of the traditional pin 2.
[0021] The outer wall of the limiting member 6 is fixedly connected to a correspondingly arranged lever 7. The lever 7 is made of metal, and the inner bottom wall of the base block 3 is made of magnetic material. The lever 7 provides a force point for rotating the limiting member 6. The operator can easily control the opening and closing of the limiting member 6 by levering the lever 7 without the need for tools, making the operation simple and convenient. When the limiting member 6 is rotated to the closed state, the metal lever 7 will attract the magnetic material of the inner bottom wall of the base block 3, fixing the position of the limiting member 6 through magnetic force, preventing the limiting member 6 from opening on its own due to shaking during wearing, and further improving the fastening stability. In addition, the end of the buckle pin 2 near the mounting block 1 is fixedly connected to a limiting block 8. This limiting block 8 can limit the rotation range of the buckle pin 2, preventing the buckle pin 2 from rotating excessively and colliding with the brooch body. At the same time, it can also assist in positioning during wearing, ensuring that the buckle pin 2 maintains a stable angle after being inserted into clothing.
[0022] When wearing the brooch, first rotate the pin 2 around the inner wall of the mounting block 1 to the open state. Hold the brooch body and align the tip of the pin 2 with the appropriate position on the clothing to be worn. Slowly insert the pin into the clothing. After the pin 2 has completely passed through the clothing, move the lever 7 of the limiting member 6 at the buckle 4 to make the limiting member 6 rotate around the buckle 4 until the opening of the limiting member 6 is misaligned with the notch 5 of the buckle 4. The annular limiting member 6 completely covers the connection between the bottom block 3 at the end of the pin 2 and the buckle 4. The limiting member 6 can completely cover the sharp end of the pin 2. Even if the skin comes into contact with the accessory when wearing it, it will not be scratched. This completely solves the safety hazard problem of the traditional pin 2 without a sealing structure.
[0023] After the limiting piece 6 is closed, the metal lever 7 is tightly attracted to the magnetic material of the inner bottom wall of the base block 3, and the position of the limiting piece 6 is fixed by magnetic force. At the same time, the end of the buckle pin 2 is engaged with the buckle head 4 through the base block 3. Combined with the ring-shaped wrapping of the limiting piece 6, a double fixation of "magnetic attraction + structural engagement" is formed. This double engagement method replaces the traditional single buckle pin 2 insertion fixation. Even if it is touched by external force during wearing, the buckle pin 2 is not easy to loosen, which can effectively prevent the brooch from slipping off the clothing, avoid damage or loss of the jewelry due to slipping, and ensure the stability of the brooch after wearing.
[0024] When you need to remove the brooch, simply pinch the metal lever 7 and apply external force to overcome the magnetic attraction. Move the lever 7 to align the opening of the limiting piece 6 with the notch 5 of the buckle 4. At this time, the limiting piece 6 will open, and you can then pull the brooch 2 out of the clothing. The entire disassembly process does not require complicated operations. The opening and closing of the limiting piece 6 can be controlled by the lever 7, making the operation convenient and efficient.
[0025] The working principle of this utility model is as follows: the U-shaped base block 3 and the ring-shaped limiting part 6 work together to seal the tip of the buckle pin 2 to eliminate safety hazards. The magnetic adsorption and double fastening structure enhance the wearing stability. The detachable design and the operation of the lever 7 enable convenient use and maintenance. Ultimately, it solves the problems of large safety hazards and unstable fastening of traditional brooch accessories, and meets the use needs of brooches that combine decoration and practicality.
