These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] To address the aforementioned issues, this application provides a quick-release magnetic clasp that offers fast magnetic attraction and unlocking, high durability, and strong practicality.

[0033] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. Example 1

[0034] Referring to Figures 1 to 4, this embodiment proposes a quick-release magnetic snap fastener, including a first snap body 1, a second snap body 2, and a trapezoidal fitting structure. The trapezoidal fitting structure includes a trapezoidal boss 11 on the first snap body 1 and a trapezoidal groove 21 on the second snap body 2, the trapezoidal groove 21 and the trapezoidal boss 11 having complementary shapes. A first magnetic element 12 is embedded in the center of the trapezoidal boss 11, and a second magnetic element 22, magnetically attracted to the first magnetic element 12, is embedded in the center of the trapezoidal groove 21. The first snap body 1 and the second snap body 2 achieve magnetic locking or separation through the fitting of the trapezoidal fitting structure.

[0035] Magnetic-assisted initial positioning and trapezoidal structure resist lateral shear force; after fitting, mechanical interlocking and magnetic attraction provide dual fixation, significantly improving tensile strength.

[0036] Furthermore, the narrow side of the trapezoidal groove 21 is provided with a locking position 211 to restrict the sliding direction of the trapezoidal boss 11; the inclined surface of the trapezoidal boss 11 can slide along the trapezoidal groove 21 to the wide end to disengage.

[0037] The locking position prevents accidental disengagement in the vertical direction, while the inclined sliding surface enables quick one-handed disassembly. The operating direction is perpendicular to the magnetic attraction direction to avoid accidental separation.

[0038] Furthermore, an isolation line 3 is provided between the two sides of the trapezoidal boss 11 and the two sides of the trapezoidal groove 21 to maintain the gap between the first buckle body 1 and the second buckle body 2.

[0039] Avoid direct friction between the two buckle bodies to reduce wear and noise; maintain the gap to ensure smooth sliding and extend service life.

[0040] Furthermore, the isolation line 3 is provided on both sides of the second buckle body, and the second buckle body 2 is provided with hollow rings 23 at a position away from the trapezoidal groove 21 and the isolation line. There are two hollow rings 23, which are located on the left and right sides of the second buckle body 2 respectively.

[0041] Reduces weight by 30%; increases edge elasticity of the buckle body to adapt to curved surface installation; the hollowed-out area facilitates screw installation of the second buckle body.

[0042] Furthermore, the trapezoidal boss 11 has a hollow opening position 111 in the middle; the trapezoidal groove 21 has a protrusion 212 in the middle, and the second magnetic suction member 22 is embedded in the protrusion 212; by applying a force perpendicular to the trapezoidal fitting structure to the opening position 111, the first buckle 1 and the second buckle 2 are separated.

[0043] Furthermore, the second buckle body 2 has a hollow structure 24 that extends through its thickness in the middle.

[0044] Further reduce the overall weight; increase breathability, while concealing screw marks from the installation of the second fastener.

[0045] Furthermore, the first buckle body 1 has four screw holes 13 around its back side.

[0046] Evenly distributes tension to prevent fabric tearing; concealed screws enhance aesthetics.

[0047] The quick-release magnetic buckle also includes a thin pressure film accessory 4, which completely covers the first buckle body 1 and is adapted to the screw hole 13 and the opening position of the first magnetic component 12 for fixing the screw on the hole.

[0048] Furthermore, the surface of the quick-release magnetic buckle is provided with anti-slip strips, and anti-slip particles are distributed around the periphery of the first buckle body and the second buckle body.

[0049] Furthermore, the outer edges of the first magnetic suction member 12 and the second magnetic suction member 22 are covered with an anti-detachment layer, which is bonded to the inner wall of the trapezoidal boss 11 and the trapezoidal groove 21.

[0050] Waterproof and rustproof; cushions the magnetic impact to prevent the magnet from breaking.

[0051] Pre-installation during use:

[0052] The first buckle 1 is fixed to the fabric / leather A through the four screw holes 13 on the back and the annular pressure fitting 4 (the screws pass through the fabric / leather to lock it); the second buckle 2 is fixed to the fabric / leather B through the hollow ring (the screws pass through the hollow ring to lock it), and the hollow structure 24 in the middle reduces the pressure on the fabric and makes it easier to hide the screw holes.

[0053] When in use, the magnetic attraction locks in place within one second:

[0054] When fabric / leather A and fabric / leather B are brought close together, the first magnetic 12 and the second magnetic 22 automatically attract each other, guiding the trapezoidal boss 11 to slide into the trapezoidal groove 21; the locked position 211 limits the movement, completing the mechanical fitting.

[0055] When in use, quick detach in one second (two modes):

[0056] (i) Sliding separation: Slide along the inclined surface of the trapezoidal boss to the narrow end to achieve separation; (ii) Pulling separation: Apply a pulling force perpendicular to the mating surface to directly separate the boss from the groove. Example 2

[0057] Combination Figure 5 and Figure 7As shown, this second embodiment also provides a quick-release magnetic buckle, the basic concept of which is the same as that of the first embodiment, the main difference being the overall structure of the first buckle body and the first buckle body.

[0058] Referring to Figures 1 to 7, based on the same concept as Embodiment 1 described above, this embodiment also proposes:

[0059] Both the first buckle body 1 and the second buckle body 2 have thin pressing edges 5 on their sides; the projected area of ​​the pressing edges 5 is larger than the projected area of ​​the buckle body body.

[0060] The trapezoidal interlocking structure is separated by applying tension to the clamping edge 5. This increases the force-bearing area and reduces the intensity of operation; it can still be operated with gloves or when wet.

[0061] In Embodiment 1, the first and second fasteners are fixed by screws through holes, while in Embodiment 2, the first and second fasteners are secured to the fabric by sewing thin sheets along the edges.

[0062] In use, the thin pressing edges of the first buckle body 1 and the second buckle body are pre-sewn onto the fabric / leather. The first buckle body 1 is provided with a trapezoidal boss 11, the center of which is embedded with a first magnetic attractor 12; the second buckle body 2 is provided with a trapezoidal groove 21 with a complementary shape, the center of which is embedded with a second magnetic attractor 22. The two are magnetically attracted to each other (such as N and N poles matching); when the boss 11 and the groove 21 are fitted, the magnetic attractor automatically attracts and aligns, and the inclined guide makes the fitting smooth.

[0063] During separation, (i) sliding separation: sliding along the inclined surface of the trapezoidal boss to the narrow end to achieve separation; (ii) pulling separation: applying force along the thin pressing edge of the first and second buckles to separate the magnetic clasp.

[0064] Effects:

[0065] Magnetic-assisted initial positioning and trapezoidal structure resist lateral shear force; after fitting, mechanical interlocking and magnetic attraction provide dual fixation, significantly improving tensile strength.

[0066] The technical solution provided in this application has the following beneficial effects:

[0067] 1. Trapezoidal interlocking and magnetic double-locking: The trapezoidal inclined surface interlocking design resists lateral shearing force and prevents shaking. The magnetic components can automatically correct positional deviations within a short distance, improving the efficiency of blind operation.

[0068] 2. Quick-release system for one-second separation: Provides two operation scenarios, pull-type separation and sliding separation, to achieve labor-saving one-handed operation.

[0069] 3. Durability Enhancement Design: The isolation line prevents direct friction between the boss and the groove, while also providing a basis for quick release, improving practicality and durability.

[0070] 4. Wide adaptability: Compatible with fabrics of different thicknesses in multiple implementation scenarios (screw fixing or sewing).

[0071] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
