Description

Technical Field

[0001] This invention relates to the field of fastener technology, specifically to a magnetic safety fastener. Background Technology

[0002] In daily life and many work scenarios, various fasteners are widely used to connect and secure items to meet different usage needs. For example, in the field of outdoor sports equipment, it is necessary to reliably connect accessories such as backpacks and clothing to the main equipment; in industrial production, fasteners are also indispensable for securing some tools and components. However, existing fasteners have many problems, which seriously affect the user experience and efficiency.

[0003] Traditional fastener installation is often cumbersome, requiring complex tools and precise manual operation. For example, some mechanical fasteners require users to precisely align the various components and connection points; even slight deviations can prevent proper installation. This not only consumes a significant amount of time but also demands a certain level of user skill, making installation difficult for unfamiliar users. Disassembly of traditional fasteners is similarly inconvenient. Many fasteners require specific tools or must be disassembled in a specific order and manner; otherwise, disassembly may fail or even damage the fastener. Furthermore, some fasteners require considerable force to disassemble, making them very difficult for users with less strength. Summary of the Invention

[0018] During installation, if Figure 5 As shown, the first clip 2 is installed on the second clip 3. The magnet 22 on the first clip 2 and the magnet 33 on the second clip 3 attract each other, completing the first step of installation. Figure 6 The second installation step is completed by installing the pair of latching posts 411 on the pair of side latches 4 into the latching grooves 341 on the second latch 3. Figure 7 As shown, the buckle body 1 is installed on the pre-installed buckle assembly. Under the action of the magnet 17 on the buckle body 1, the magnet 32 ​​on the second buckle 3, the magnet 18 on the buckle body 1 and the magnet 22 on the first buckle 2, they attract and hold each other, completing the third step of installation. Installation is complete. To disassemble, press the pair of levers 13 on both sides to separate the buckle body 11 and the buckle assembly, thus completing the disassembly of the safety buckle.

[0019] Based on the above implementation scheme, the grip 13 has a concave groove 132 inside, and the deformation ring 12 has a pair of convex circles 121 installed inside the concave groove 132; a protective cover 16 is also installed on the buckle body 11.

[0020] Based on the above implementation scheme, the first buckle 2 includes a buckle body 21, on which a magnet groove 212 is provided, and a magnet 22 is installed inside the magnet groove 212.

[0021] Based on the above implementation scheme, the second buckle 3 includes a second buckle body 31, on which a magnet groove 4 312 and a magnet groove 5 313 ​​are provided. A magnet 4 32 is installed inside the magnet groove 4 312, and a magnet 5 33 is installed inside the magnet groove 5 313. A cover 1 34 is installed on the outside of the second buckle body 31.

[0022] Working principle: During installation, if... Figure 5 As shown, the first clip 2 is installed on the second clip 3. The magnet 22 on the first clip 2 and the magnet 33 on the second clip 3 attract each other, completing the first step of installation. Figure 6 The second installation step is completed by installing the pair of latching posts 411 on the pair of side latches 4 into the latching grooves 341 on the second latch 3. Figure 7 As shown, the buckle body 1 is installed on the pre-installed buckle assembly. Under the action of the magnet 17 on the buckle body 1, the magnet 32 ​​on the second buckle 3, the magnet 18 on the buckle body 1 and the magnet 22 on the first buckle 2, they attract and hold each other, completing the third step of installation. Installation is complete. To disassemble, press the pair of levers 13 on both sides to separate the buckle body 1 and the buckle assembly, thus completing the disassembly of the safety buckle. During installation, if Figure 10 As shown, when the buckle body 1 approaches the buckle assembly, the two pairs of magnets, magnet 17 and magnet 32, magnet 18 and magnet 32, attract each other. At this time, the inclined surface 151 is pushed open by the inclined surface 321, causing the locking tongue 15 to be pushed outward until the two pairs of magnets, magnet 17 and magnet 32, magnet 18 and magnet 32, attract each other. Finally, the locking tongue 15 is pushed back under the action of the spring 14, completing the reset. At this time, the locking tongue 15 is locked in the groove of the buckle body 31, and the safety buckle is installed.

[0023] During disassembly, if Figure 11 As shown, when the handle 13 is squeezed, the deformation ring 12 deforms under the action of force, and the two ends slide outward, driving the locking tongue 15 to unlock. At the same time, the inclined groove 131 on the handle 13 and the inclined surface 412 on the side buckle 4 move with each other, separating the buckle body 1 from the other buckles. Finally, the buckle body 31 and the buckle body 11 are separated. At this time, the two pairs of magnets, magnet 17 and magnet 4 32, magnet 1 18 and magnet 3 22, can no longer attract each other or the attraction between them is reduced, thereby separating the buckle body 1 and the buckle assembly. Then, the side buckles 4, the second buckle 3, and the first buckle 2 on the left and right sides are disassembled to complete the final disassembly step.
