Description

Technical Field

[0001] This utility model belongs to the field of chain buckle technology, specifically relating to a chain buckle that provides stable wearing. Background Technology

[0002] In daily life, chain clasps are important connecting components of various jewelry chains (such as necklaces and bracelets), directly affecting the stability and convenience of wearing them. However, existing chain clasp designs have some shortcomings.

[0003] Existing chain clasps may come loose unexpectedly during wear. Traditional clasp structures typically use simple snap-on or screw-on connections. Although simple in structure, these connections may loosen under external force or prolonged wear, causing the chain to become unstable or even fall off unexpectedly. Furthermore, a loose clasp also increases the risk of losing the jewelry, adding to the user's burden.

[0004] Current chain buckle designs also have room for improvement in terms of ease of disassembly. Some chain buckles have complex structures, making disassembly cumbersome, especially for users with limited hand strength or dexterity, making it difficult to put on and take off the chain. Traditional screw-on buckles, while secure, require users to tighten and loosen them, which is inconvenient and time-consuming. This complex operation reduces the user's wearing experience and does not meet modern people's demand for quick and convenient wearing methods.

[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0020] like Figures 1 to 4 As shown, a chain buckle with stable wear includes a first buckle 10 and a second buckle 20. The first buckle 10 is recessed with a mounting groove 11, and one end of the second buckle 20 is provided with a mounting block 21. The mounting block 21 is embedded in the mounting groove 11, thereby connecting the first buckle 10 and the second buckle 20. The structure is simple and convenient for users to use.

[0021] In practical implementation, the second buckle 20 has a recessed locking groove 22 at one end facing the mounting block 21. A return spring 23 and a locking ball 24 are respectively installed in the locking groove 22. The locking ball 24 is located at the front end of the return spring 23. The front end of the locking groove 22 has a ball opening 221. The size of the locking ball 24 is slightly larger than the size of the ball opening 221. One end of the return spring 23 is fixed to the bottom of the locking groove 22, and the other end of the return spring 23 presses against the locking ball 24, so that the locking ball 24 is pushed forward to the ball opening 221. At the same time, the front part of the locking ball 24 is embedded in the ball opening 221, forming a pre-locked state.

[0022] In practical implementation, the front end of the mounting groove 11 is provided with a locking protrusion 12, and the front surface of the locking protrusion 12 is provided with a locking arc groove 121 that is adapted to the locking ball 24. When the mounting block 21 is embedded in the mounting groove 11, the locking protrusion 12 is located in the rear end of the mounting block 21. At the same time, the front part of the locking ball 24 is located in the locking arc groove 121 for locking and fixing, thereby making the first buckle 10 and the second buckle 20 locked and connected. The structure is simple and convenient for users to wear daily. The locking connection method enhances the stability of the buckle, prevents accidental loosening during wearing, and ensures easy disassembly.

[0023] In practical implementation, the rear two sides of the mounting block 21 are symmetrically recessed with arc-shaped positioning grooves 211, and the left and right sides of the engaging protrusion 12 are symmetrically provided with arc-shaped positioning blocks 122. The positioning blocks 122 correspond to the positioning grooves 211. When the mounting block 21 is embedded in the mounting groove 11, the positioning blocks 122 are correspondingly embedded in the positioning grooves 211 for positioning and connection, thereby making the engagement connection between the engaging ball 24 and the engaging arc groove 121 more stable. This multi-positioning design not only enhances the locking performance of the buckle, but also ensures that the buckle has excellent anti-loosening ability in all directions during the wearing process.

[0024] In practical implementation, the rear end of the mounting groove 11 is recessed with an arc-shaped positioning groove 111, and the front end of the mounting block 21 is protruded with an arc-shaped positioning protrusion 212. The positioning protrusion 212 corresponds to the positioning groove 111. When the mounting block 21 is embedded in the mounting groove 11, the positioning protrusion 212 is correspondingly embedded in the positioning groove 111 for positioning and connection, thereby making the connection between the first buckle 10 and the second buckle 20 more stable. In use, the mutual cooperation between the positioning protrusion 212 and the positioning groove 111 forms an additional fixing point, making the connection between the first buckle 10 and the second buckle 20 more firm and reliable. This structure is simple and efficient, ensuring that the buckle always maintains a good connection during wearing, and is suitable for various environmental needs in daily use.

[0025] In practical implementation, the first buckle 10 has a first chain connecting part 13 at the end away from the second buckle 20, and the second buckle 20 has a second chain connecting part 25 at the end away from the first buckle 10. When wearing the buckle, the user connects the two ends of the chain to the first chain connecting part 13 and the second chain connecting part 25 respectively, thereby forming a closed loop. This design allows the user to easily operate the buckle to open and close the chain, while ensuring that the chain will not easily come loose during wearing, making it convenient for daily wearing and removal.

[0026] In summary, the first buckle 10 is recessed with an installation groove 11, and the second buckle 20 has an installation block 21 at one end, which is embedded in the installation groove 11. The second buckle 20 also has a locking groove 22 at one end, in which a return spring 23 and a locking ball 24 are respectively installed. The locking ball 24 is located at the front end of the return spring 23. The front end of the installation groove 11 has a protruding locking protrusion 12, and the front surface of the locking protrusion 12 has a recessed locking arc groove 121. The locking protrusion 12 is located at the rear end of the installation block 21. Simultaneously, the front part of the locking ball 24 is locked and fixed in the locking arc groove 121, thus engaging the first buckle 10 and the second buckle 20. This invention provides a simple and stable chain buckle structure, convenient for daily wear. The locking connection enhances the buckle's stability, preventing accidental loosening during wear, and ensuring easy disassembly.
