[0054] The conical bodies and the oval cylindrical body 11211 are configured to fix the first soft movable base body and prevent the first soft movable base body from moving backward after being stressed. The substantially oval cylindrical body 11211 can also be designed as an outwardly inclined conical body.

[0055] In this embodiment, the inclination direction of the cone 11212 and the cone 11213 is opposite to the orientation of the hook tail of the hooking body 123.

[0056] The inclination direction of the cone 11111, the cone 11112, and the cone 11113 is opposite to the orientation of the hook tail of the hooking body 123.

[0057] Two vertical "wing"-shaped structures 124 are provided on both sides of the first buckle body structure.

[0058] The second buckle body structure 200 is generally in the shape of a Chinese character "ri". Two substantially square through holes 210 (211, 212) are provided on the second buckle body structure 200 for preventing the hook body from falling off. An undercut structure 2111 for preventing the hook body from falling off is provided on the through hole 211, and an undercut structure 2112 for preventing the hook body from falling off is provided on the through hole 212. A circular groove 220 is provided at the bottom of the second buckle body structure 200 between the two through holes, a second circular magnet 221 is fixed in the groove 220, and a plurality of arc-shaped grooves 222 are provided on the circumferential side of the circular groove 220, and the arc-shaped grooves 222 are used for fixing the second magnet structure.

[0059] The shape of the undercut structure 2111 and the undercut structure 2112 is: the side of the through hole 211 close to the center of the second buckle body and the side of the through hole 212 close to the center of the second buckle body extend along the first surface of the second buckle body structure to the side away from the center of the second buckle body, forming a buckle-shaped structure between the first surface and the second surface of the second buckle body.

[0060] On both sides of the second buckle body structure, a horizontal structure 230 matching the "wing"-shaped structure 124 is provided. When the first buckle body 100 and the second buckle body 200 are buckled, the "wing"-shaped structure 124 and the horizontal structure 230 play a role of guiding and limiting. An arc-shaped slope structure 231 is provided on the side of the horizontal structure 231 close to the through hole 211.

[0061] An arc-shaped groove 240 is provided on the side of the hole 210 of the second buckle body structure 200 close to the outer edge, an arc-shaped groove 241 is provided on the side of the through hole 211 of the second buckle body structure 200 close to the outer edge, and a platform portion 2411 lower than the top plane of the second buckle body structure 200 is provided outside the arc-shaped groove 241. An arc-shaped groove 242 is provided on the side of the through hole 212 of the second buckle body structure 200 close to the outer edge.

[0062] The upper and lower surfaces of the second buckle structure are the first surface and the second surface, respectively. The first surface and the second surface are parallel to each other. The center of the first surface and the second surface arches upward to form an arc shape. That is, the second buckle structure arches upward along the two longer sides to form an arc shape structure at 10° with the horizontal plane. In this embodiment, the lower surface of the second buckle, that is, the second surface, is the connection part with the second movable soft substrate.

[0063] In this embodiment, the first soft movable substrate 300 is a strip structure, and the width of the strip structure 300 is the same as the width of the arc-shaped hole structure (110, 120) of the first buckle structure 100.

[0064] In the middle of the strip structure 300, there are multiple circular holes 310. When the strip structure 300 passes through the arc-shaped hole 110 and the serrated hole 120 of the first buckle structure, the elliptical column 11111 and cone 11212 on the first buckle structure 100 enter the circular holes 310. Other inclined cones are stuck into the strip structure 300 under pressure, so that the strip structure 300 will not move, thereby ensuring that the position of the first buckle structure 100 on the bag structure 300 is fixed.

[0065] In this embodiment, the second soft active substrate is typically located on the surface of the wearable device.

[0066] When it is necessary to adjust the tightness, the relative movement of the holes on the strip structure 300 relative to the elliptical column 11111 can be adjusted.

[0067] The second soft movable base can be a wearable material, such as the upper of a shoe, or a webbing. In this embodiment, it is the upper of a shoe. The second buckle structure 200 is fixedly connected to the second movable base, that is, the upper surface of the shoe or the webbing, by means of sewing. Example

[0068] like Figures 18-23 As shown, the main difference between this embodiment and embodiment 1 is that the first fastener structure a100 consists of two fasteners that are fastened together, namely the first upper fastener a110 located at the top and the first lower fastener a120 located at the bottom.

[0069] The first upper fastener a110 includes a decorative part a111 and a cylindrical snap-fit ​​part a112 located at the end. In this embodiment, the decorative part a111 is heart-shaped. Of course, the decorative part a111 can be designed into different shapes according to actual needs. The cylindrical snap-fit ​​part a112 is located at the middle position of the lower part of the arc-shaped end and passes through the circular hole of the first soft movable base 300 by snapping.

[0070] Two vertical "wing"-shaped structures a113 are provided on the two sides of the first upper fastener a110.

[0071] A horizontal slide rail a1131 is provided on each of the two inner sides of the "wing"-shaped structure a124. The first lower fastener a120 moves laterally along the slide rail to reach a preset position. A slot a1132 is provided on the bottom surface near the decorative part a111 of the first upper fastener.

[0072] The first lower fastener a120 has an upper part that is roughly triangular. A recess a121 is provided on each side of the first lower fastener a120. At one end of the recess a121, there is an upwardly oriented, roughly columnar protrusion a122. On the same side of the recess a121, there is an upwardly sloping platform a123 that slopes from the outer side to the inner side. Alternatively, it can be described as a downwardly sloping platform a123 that slopes from the inner side to the outer side. An upwardly oriented cylindrical protrusion a124 is provided on the inclined surface of the triangle of the first lower fastener a120.

[0073] The bottom of the first lower fastener a120 is horizontal, with a horizontal, downward row of protrusions at both ends. In this embodiment, the protrusion near the cylindrical protrusion a123 is a row of hook-shaped bodies a125, with the hooks of the hook-shaped bodies a125 facing forward, i.e., towards the side away from the center of the first fastener structure. The protrusion a126 near the cylindrical protrusion a122 is a long strip-shaped plate structure. In this embodiment, the cylindrical protrusion a124 and the row of hook-shaped bodies protrude in opposite directions.

[0074] A circular groove a127 is provided at the bottom of the first lower fastener a120, and a circular magnet is placed in the circular groove a127. Multiple arc-shaped grooves a1271 with the same height as the circular groove a127 are provided on the side of the groove a127.

[0075] When the first upper fastener a110 and the first lower fastener a120 are fastened together, a complete first fastener structure a100 is formed. This embodiment has the following advantages over embodiment 1: 1. It is easy to replace decorative structural parts. Due to the needs of different brand customers and users, the appearance parts and shapes can be customized. Only the mold of the first upper fastener needs to be replaced. The first upper fastener can be processed and then assembled and replaced, which is very convenient. 2. The male buckle structure better secures the magnet assembly and adjusts the webbing. Example

[0076] like Figures 24-26 As shown The first buckle body structure b100 is generally in the shape of a Chinese character "ri", comprising two arc-shaped hole structures b110 (111, 112) and a first magnet supporting table b120 located between the two arc-shaped hole structures. The first soft movable base body b300 is inserted through the two arc-shaped hole structures b110.

[0077] The main difference between this embodiment and Embodiment 1 lies in that, an approximately elliptical cylinder b1111 is arranged at the middle position on the lower side surface of the side edge b111, and the elliptical cylinder is provided with an open groove portion b11111.

[0078] On the upper part of the first magnet supporting table b120, that is, on two sides of the first face body close to the arc-shaped hole structures b110, two open grooves b121 (b1211, b1212) and b122 (b1221, b1222) facing the arc-shaped hole structures are respectively provided, and a circular column b123 protruding upward is provided between the two open grooves b1221 and b1222.

[0079] On the lower part of the first magnet supporting body b120, that is, four supporting structures b1241 are symmetrically arranged at the bottom of the circular groove b124 on the second face body, and the supporting structures b1241 are respectively located around the circular groove b122. Example

[0080] In the technical solution of the present utility model The tail of the hook body has an upward tilted angle, and in this embodiment, the angle is 45°, and the tensile force it can bear can reach more than 20 kilograms (≥20kg).

[0081] The adjustment and improvement of the new magnetic suction buckle in the production process enable it to maintain stable performance at -40°C to 80°C (the temperature of the shoe setting oven is 80°C). Material: It is formed by injection molding using nylon A3K material. It is wear-resistant, has high toughness, impact resistance, high and low temperature resistance, and the plastic raw material has wear resistance and high fluidity.

[0082] Good flexibility: It increases adjustment and flexibility functions. Ordinary hook and loop fasteners are mostly made of fabric or ordinary nylon material, and their flexibility and adjustment performance will degrade after long-term use. The magnetic adjustable buckle perfectly solves this shortcoming, its flexibility function and adjustment function remain unchanged, it is durable, and can realize quick magnetic disassembly and suction connection. Magnetic suction buckling and quick disassembly: The addition of a magnet facilitates alignment, and an inverted buckle design is adopted to generate reverse pulling force.

[0083] Under the same specifications of magnetic materials, the volume of the magnet is proportional to the magnetic force. Since the role of the magnet in this invention is mainly to find the correct position, the requirement for the magnitude of the magnetic force is not high. It is sufficient to select a suitable magnet specification, which can be square, round, or long strip, making it easier to control the volume of the magnet and achieve multi-level magnetic attraction. After assembling the magnet, it is filled with magnetizing sealant, which avoids the inconvenience of storage caused by pre-magnetizing.

[0084] The development process of combining magnetic buckles with shoes involved repeated testing and verification. The structure of the magnetic buckle is well-suited to sandals, beach shoes, and other footwear with webbing. The multi-section adjustable magnetic buckle allows for quick and easy opening and closing, improving the convenience and simplicity for users when wearing shoes.

[0085] It should be noted that the function of the first and second magnetic fasteners on the upper and lower fasteners is to position the hook-shaped parts, which can make the hook-shaped parts and fasteners on the upper and lower fasteners find their correct positions more quickly, that is, to play a positioning role.

[0086] The magnetic snap fastener of this invention allows for quick magnetic engagement and disengagement via a simple pull, making it extremely convenient. It can be applied to various shoes, clothing, backpacks, and other DIY products. The main body can be bent into a slight arc for a better fit, allowing for adjustments to length and looseness, thus providing convenience, novelty, and practicality.

[0087] The following is a specific application scope of this school: 1. Shoes: Women's shoes, high heels, princess shoes, sandals, Birkenstocks; 2. Clothing: Pants, down jacket, ski suit, chemical protective suit, tactical work clothes, vest, life jacket; 3. Bags and luggage: school bags, waist bags, hiking backpacks, casual bags, handbags, shoulder bags, and travel cases; 4. Underwear: Outdoor sports, running backpacks, vests; 5.
