Description

Technical Field

[0001] This utility model relates to magnetic snap fastener technology, and more particularly to a high-strength magnetic snap fastener. Background Technology

[0002] Traditional outdoor sports shoes, such as beach shoes and river tracing shoes, often use Velcro or mechanical buckles for fastening. While Velcro is inexpensive, it is prone to failure in water or dusty environments due to the adhesion of sand and hair, and its stickiness weakens with repeated use, posing a risk of loosening. Mechanical buckles, on the other hand, usually require precise alignment and pressure from both hands to fasten, which is inconvenient for outdoor activities or one-handed operation; they are also difficult to unfasten.

[0003] Existing technologies include Chinese patent applications with publication numbers CN201920707928, CN201780065029, and CN2013800764574. These patents propose a method for quick engagement using magnetic attraction. However, the release mechanism typically still relies on traditional methods such as horizontal pulling or pressing a button. This approach still suffers from the following inherent drawbacks: Directly resisting the magnetic force by pulling laterally requires considerable strength, especially when the magnetic force is strong enough to ensure a secure fastening, making release difficult.

[0004] When subjected to a diagonal pulling force in a specific direction, traditional magnetic fasteners may be accidentally pulled open due to the lever arm, resulting in insufficient safety and reliability.

[0005] Some of them use a magnetic structure with levers or buttons for unlocking. They have more internal components, which increases production costs and failure rate. In addition, the complex structural gaps are more likely to become clogged or corroded in sandy or muddy environments, affecting their service life.

[0006] Therefore, there is an urgent need in this field for a new type of magnetic fastener that can retain the convenience of magnetic fastening, achieve faster, less effort, and more reliable one-handed release, while also being structurally robust and durable, and capable of differentiated design in terms of patent layout. Utility Model Content

[0007] To address the shortcomings of the existing technology, this invention proposes a high-strength magnetic clasp.

[0008] The technical solution of this utility model is implemented as follows: A high-strength magnetic snap fastener includes a female snap assembly and a male snap assembly. Its features are, The female buckle assembly includes a female buckle body and a lower magnet fixed therein; The male buckle assembly includes a male buckle body, an upper magnet fixed therein, and a metal rotating component; The male buckle body can be released and fastened to the female buckle body by the magnetic attraction force of the upper and lower magnets; The metal rotating component is rotatably disposed at one end of the male buckle body and is connected to a pull head. By pulling the pull head upward at an angle, the metal rotating component causes the male buckle body to rotate and disengage relative to the female buckle body in one direction.

[0009] Preferably, the top periphery of the female buckle body is provided with an upwardly extending peripheral baffle, and when fastened, at least part of the peripheral baffle surrounds the male buckle body.

[0010] Preferably, the female buckle body is provided with a first engagement block, and the male buckle body is provided with a second engagement block that cooperates with the first engagement block.

[0011] Preferably, the male buckle body is provided with a second magnet mounting cavity, the upper magnet is housed in the second magnet mounting cavity and encapsulated by a decorative component.

[0012] Preferably, one end of the female buckle body is provided with a first connecting groove for fixing the connecting webbing.

[0013] Preferably, one end of the female buckle body is provided with an arc-shaped groove, and the metal rotating part uses the arc-shaped groove as a fulcrum when it is pulled at an angle.

[0014] Preferably, the metal rotating component is engaged within the arc-shaped slot.

[0015] Preferably, the male buckle body is housed within the peripheral baffles on both sides of the female buckle body, and the inner side of the peripheral baffles is provided with a locking block.

[0016] Preferably, the locking block has a partial hook structure, and the inner two sides of the hook structure are provided with bevels.

[0017] Preferably, hook grooves are also provided on both sides of the male buckle body. When the female buckle body and the male buckle body are engaged, the locking block is located in the hook groove, and the hook structure guides the locking block into the hook groove.

[0018] Preferably, the locking block and the female buckle body are integrally formed, which improves the overall structural strength.

[0019] Preferably, the zipper pull can be a woven label, webbing, or pull cord.

[0020] Preferably, the female buckle body is sewn and fixed with the edges extending from the four sides of the base.

[0021] The high-strength magnetic clasp of this utility model has the following beneficial effects: 1. The peripheral baffle at the top of the female buckle body forms a rigid enclosure from the side after the male buckle assembly is engaged. This structure not only effectively prevents the male buckle assembly from shifting or swaying in any direction in the horizontal plane, but also greatly limits the warping tendency caused by uneven tension, providing a basic stable framework for the entire fastening system.

[0022] 2. The first and second engagement blocks, located on the female and male buckle bodies, interlock after fastening. When the webbing is subjected to lateral tension, they efficiently convert the lateral force and torsional torque into pressure between the engagement surfaces, rather than separation force, thereby effectively resisting rotation and lateral displacement and ensuring that the fastener remains locked in a dynamic environment.

[0023] 3. The beveled design on both sides of the inner side of the locking block on the female buckle not only guides the male buckle during engagement, facilitating its sliding in, but more importantly, after engagement, the locking block and the corresponding part of the male buckle body fit tightly together, like a "hook," resisting the overturning torque that could lift the front end of the male buckle. This design prevents the male buckle assembly from accidentally unlocking by "lifting its head" with its tail as a fulcrum when pulled forward or scraped by ground obstacles, maintaining the balance of the engaged posture.

[0024] 4. The main body of the female buckle is usually made of one piece, and its base design has sufficient rigidity. When subjected to tension, the force can be evenly distributed through the base, avoiding stress concentration in weak areas such as webbing seam points or magnet mounting cavities. This improves connection reliability and extends product lifespan. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Reference Figures 1 to 2 As shown, this embodiment proposes a specific structure for a high-strength magnetic snap fastener, including a female snap fastener assembly 10 and a male snap fastener assembly 20. The female snap fastener assembly 10 and the male snap fastener assembly 20 engage with each other to complete the fastening. When it is necessary to release the fastener, refer to... Figure 2 As shown, pull up the male buckle assembly 20 to separate it from the female buckle assembly 10 and release the fastening.

[0029] Specifically, refer to Figure 3 As shown, the female buckle assembly 10 consists of a female buckle body 101, a lower magnet 102, and a webbing 103. The lower magnet 102 is embedded in the bottom of the female buckle body 101, and the webbing 103 is connected to one end of the female buckle body 101.

[0030] The male buckle assembly 20 consists of a decorative part 201, an upper magnet 202, a metal rotating part 203, a male buckle body 204, and a pull head 205.

[0031] The zipper pull 205 can be made of webbing, woven label or pull cord.

[0032] The upper magnet 202 is installed on the male buckle body 204 and is completely sealed inside the male buckle body 204 by the decorative piece 201. The metal rotating part 203 is snapped onto one end of the male buckle body 204, and the pull head 205 is connected to the end of the male buckle body 204 away from the metal rotating part 203.

[0033] In this embodiment, when the user brings the male fastener assembly close to the female fastener assembly, the female fastener assembly 10 and the male fastener assembly 20 will automatically align and snap together under the strong magnetic force of the upper magnet 202 and the lower magnet 102. This process does not require visual alignment and can be performed blindly with one hand, which is extremely convenient.

[0034] When it is necessary to untangle, the user does not directly resist the vertical pull of the magnetic force, but pulls the pull head 205 upwards at an angle. At this time, the upward pulling force will act on the metal rotating part 203, forming a lever with the contact point between the male buckle body 204 and the female buckle body 101 as the fulcrum.

[0035] Under the action of leverage, the metal rotating component 203 causes the male buckle body 204 to rotate slightly. After rotation, the magnetic adsorption surfaces of the male buckle body 204 and the female buckle body 101 change from a full-area adsorption state of "face to face" to a separated state of "side offset", thereby reducing the adsorption force between the magnets. At this time, only a very small continuous pulling force is needed to completely detach the male buckle body 204 from the female buckle body 101.

[0036] Furthermore, referring to Figures 4 to 7 As shown, the bottom of the female buckle body 101 has a first magnet mounting cavity 101A, and the lower magnet 102 is embedded in the first magnet mounting cavity 101A. The bottom of the female buckle body 101 is fitted against an inclined surface to prevent the lower magnet 102 from falling out.

[0037] The webbing is firmly pressed or sewn between the bottom of the female buckle body 101 and the lower magnet 102. The base of the female buckle body 101 is equipped with a rigid webbing anchor point area, which allows the tensile force to be distributed more evenly across the entire base of the female buckle body 101, rather than being concentrated at a weak point, greatly reducing the risk of the webbing being pulled off or the base of the buckle body 101 being torn.

[0038] One end of the female buckle body 101 is provided with a first connecting groove 101B, which is used to connect with the webbing 103. The webbing 103 is part of the shoelace of an outdoor beach shoe.

[0039] The female buckle body 101 has peripheral baffles 101C on both sides of its top. The male buckle body 204 is housed in the peripheral baffles 101C on both sides of the female buckle body 101. The inner side of the peripheral baffles 101C is provided with a locking block 101D.

[0040] Specifically, the base of the female buckle body 101 is designed with raised annular reinforcing ribs or a surrounding structure. When the male buckle body 204 is snapped in, the base of the male buckle body 204 is wrapped and supported from the side by the peripheral baffle 101C and the locking block 101D to improve the stability of the connection.

[0041] The female buckle body 101 has an arc-shaped groove 101E at one end away from the first connecting groove 101B. The arc-shaped groove 101E is used to provide a fulcrum for the metal rotating part 203. A first engagement block 101F is provided in the middle of the arc-shaped groove 101E.

[0042] In this embodiment, a second connecting groove 204A is provided at one end of the male buckle body 204, and the second connecting groove 204A is connected to the pull head 205. A second magnet mounting cavity 204B is provided in the middle of the male buckle body 204, and the second magnet mounting cavity 204B is used to mount the upper magnet 202. A decorative piece 201 is installed above the second magnet mounting cavity 204B to completely seal the upper magnet 202 inside the male buckle body 204.

[0043] Preferably, the decorative element 201 is made of plastic or metal.

[0044] The male buckle body 204 is located at one end away from the second connecting groove 204A and is disposed in the arc-shaped groove 204D, which is used to engage the metal rotating part 203.

[0045] A second engagement block 204E is provided on one side of the arc-shaped slot 204D. When the male fastener assembly approaches the female fastener assembly, the first engagement block 101F and the second engagement block 204E engage with each other.

[0046] When the shoelaces or webbing are subjected to lateral pulling (such as being caught on a tree branch or accidentally collided with the feet), the first biting block 101F and the second biting block 204E engage with each other to resist the resulting torsional torque and lateral force, preventing excessive deformation or displacement between the female buckle body 101 and the male buckle body 204, thereby avoiding accidental loosening.

[0047] The male buckle body 204 is also provided with hook grooves 204C on both sides. When the female buckle body 101 and the male buckle body 204 are engaged, the locking block 101D is located in the hook groove 204C and is guided by the hook structure to enter the hook groove 204C.

[0048] In one embodiment, refer to Figure 8 As shown, the pull head 205 is either a woven label or a pull cord.

[0049] Preferably, the female buckle body is connected to the product by means of webbing, sewing, or riveting, extending from the four sides of the base.

[0050] In this embodiment, a high-strength magnetic clasp is applied to beach shoes. Preferably, see... Figures 9 to 16 As shown, a high-strength magnetic buckle can also be applied to women's shoes, high heels, princess shoes, sandals, Birkenstocks, etc. The rotating unlocking mechanism avoids the small gaps of traditional snap fasteners and the adhesive surface of Velcro, effectively preventing sand and mud from getting in and causing jamming, ensuring reliable function even in dirty environments. Magnetic attraction allows for blind operation, eliminating the need for precise alignment; the angled pull unlocking method requires far less finger grip than pinch-button fasteners, allowing for easy operation even with wet hands or thick gloves. Through the interlocking blocks and surrounding baffles, it effectively resists multi-directional impacts generated during running, climbing, or tactical movements, preventing the buckle from loosening due to accidental snagging or impact, ensuring safety during sports activities.

[0051] Preferably, a high-strength magnetic buckle can also be applied to clothing, such as trousers, down jackets, ski suits, chemical protective suits, tactical work clothes, vests, life jackets, etc.

[0052] Magnetic snaps offer unparalleled ease of closure, meeting the need for quick access to items; in emergencies (such as the need to quickly put on a life vest), a simple diagonal pull allows for quick release. During prolonged carrying, walking, or running, continuous vibration can easily cause traditional snaps to gradually loosen. This design combines an interlocking structure with strong magnetic force, providing continuous locking force under dynamic conditions, excellent vibration resistance, and preventing accidental opening during travel. The even distribution of webbing tension, combined with mechanical interlocking, ensures that the snap points remain secure even when the bag is heavy, with a load-bearing capacity far exceeding that of ordinary magnetic snaps.

[0053] Preferably, a high-strength magnetic buckle can also be applied to bags, such as backpacks, waist bags, hiking bags, casual bags, handbags, shoulder bags, and suitcases.

[0054] The three-dimensional restraint formed by the surrounding baffles and interlocking blocks can effectively resist accidental collisions and impacts, preventing the buckles from popping open due to external force in the event of an accident, and providing users with crucial passive safety protection.

[0055] Preferably, a high-strength magnetic clasp can also be applied to underwear, such as sports bras or vests.

[0056] Preferably, a high-strength magnetic clasp can also be used on ornaments, such as watch and keychain pendants.

[0057] Preferably, a high-strength magnetic buckle can also be applied to hats, helmets, etc.

[0058] Preferably, a high-strength magnetic buckle can also be applied to medical devices, such as stretchers, orthotics, and medical protective gear. It offers significant advantages in terms of ease of unfastening, making it particularly suitable for users with limited strength, enabling them to easily put on and take off protective gear themselves, improving their self-care ability and dignity. It ensures that the protective gear remains in the correct position required for treatment, providing continuous and reliable support and fixation, which is beneficial for rehabilitation.

[0059] Preferably, a high-strength magnetic clasp can also be applied to baby products, such as baby carriers, strollers, and baby slings.

[0060] Preferably, a high-strength magnetic buckle can also be applied to pet supplies, such as magnetic pet harnesses or dog leashes.

[0061] When applied to beach shoes, which are frequently used in water, feet and hands become slippery. Traditional buckles may be difficult to tighten or press due to the slipperiness. A diagonal pull motion is easier to apply force than precisely pressing a button, offering a higher margin of error. Furthermore, sand particles can easily get into the gaps, increasing friction and potentially causing the shoe to jam. A rotation-based release mechanism effectively eliminates the obstruction of tiny sand particles, resulting in higher reliability.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
