Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a magnetic fastener. Background Technology

[0002] Magnetic snaps, a common type of fastener, are widely used in various bags, clothing, and other products. They utilize magnetic attraction combined with a directional snap-fit ​​structure to open and close product openings, facilitating the storage and retrieval of items. Currently, most magnetic snaps on the market are single-piece, single-sided snap-fit ​​structures, which suffer from issues such as weak adhesion and easy lifting without a snap-fit ​​point, affecting product appearance and user experience. Furthermore, this type of structure requires moving in the opposite direction of the snap-fit ​​when opening, making the operation method simplistic and inconvenient.

[0003] Some products use a double inverted structure with two identical inverted structures. Although this improves the tightness of the adsorption, it still requires moving in the opposite direction of the inverted structure when opening the lid. The opening method is still limited and cannot meet the needs of practical use for convenience and diverse operation methods.

[0004] Taking a backpack as an example, its clasp typically has two fastening points, requiring the use of two magnetic snaps. In current technology, the two magnetic snaps must be operated separately, and simultaneous opening is not possible. Users need to use both hands to complete the opening action, which is cumbersome and affects the efficiency of use.

[0005] In conclusion, how to effectively solve the problems of limited magnetic snap-on opening methods, inconvenient operation, and poor user experience is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a magnetic clasp that has multiple unhooking methods, is easy to operate, and improves the user experience.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A magnetic snap includes an upper magnetic snap piece and a lower magnetic snap piece. The outer surfaces of the upper and lower magnetic snap pieces are fixedly connected to a flap and a flap body, respectively. Magnets that can magnetically attract each other are respectively provided at corresponding positions inside the upper and lower magnetic snap pieces. The inner surface of the upper magnetic snap piece has a snap, and the inner surface of the lower magnetic snap piece has a fastening groove that mates with the snap to achieve connection between the snap and the fastening groove. The fastening groove has a surface groove on the inner surface of the lower magnetic snap piece so that the snap can fasten with the fastening groove through the surface groove. The snap includes a hook body and a hook back, wherein the hook body faces opposite to the hook back. The fastening groove has a clearance space on the side where the hook back is located so that the upper magnetic snap piece at the end away from the hook body can be flipped away from the lower magnetic snap piece to achieve unfastening.

[0009] Furthermore, the fastening groove is configured to release the buckle when the buckle slides in a direction away from the direction in which the hook body is facing.

[0010] Optionally, the hook back of the buckle is an inclined surface, and the fastening groove is provided with a chamfered surface that matches the inclined surface to form the clearance space.

[0011] Optionally, at least one side of the fastening groove passes through the side edge of the lower magnetic snap piece to form a side groove, allowing the buckle to slide along the side groove direction to unfasten.

[0012] Optionally, the upper magnetic snap plate has two inverted snaps arranged in the longitudinal direction, and the lower magnetic snap plate has two fastening grooves that cooperate with the inverted snaps, with the side openings of the two fastening grooves facing the same direction.

[0013] Optionally, the number of magnetic snaps is two, and the two magnetic snaps are arranged in parallel in the lateral direction. The side slots on the two magnetic snaps are set to the same direction or opposite directions.

[0014] Optionally, the fastening groove is a through groove that extends through both sides of the lower piece of the magnetic buckle.

[0015] Optionally, the buckle is divided into a hook buckle and a straight buckle. The hook body of the hook buckle includes a vertically arranged vertical surface and a horizontal surface to form an L-shaped structure, and the hook body of the straight buckle is an inclined surface parallel to the inclined surface.

[0016] Optionally, of the two buckles on the magnetic snap upper piece, the one closer to the flip end is a straight buckle, and the one farther from the flip end is a hook buckle, with the angle of inclination of the hook buckle and the angle of inclination of the straight buckle being the same.

[0017] Optionally, the root of the hook of the straight buckle is provided with a vertical surface, which is connected to the inclined surface to form a bend structure; the width of the root of the straight buckle is greater than the width of the end.

[0018] Optionally, the outer surfaces of the upper and lower magnetic buckle pieces are respectively provided with mounting holes for accommodating the magnets, and the magnets are fixedly connected to the mounting holes by an interference fit.

[0019] The beneficial effect of this utility model is that the magnetic snap provided by this utility model has a surface groove on the inner surface of the lower magnetic snap piece, which allows the snap to enter or exit the fastening groove by inverting. When the snap is inserted into the fastening groove, the upper and lower magnetic snap pieces are fastened together. When the snap is pulled out of the fastening groove, the upper and lower magnetic snap pieces are unfastened.

[0020] During the fastening process, when the upper and lower magnetic snap pieces come close, the internal magnets attract each other, automatically guiding them to align and fit together, achieving initial positioning. Simultaneously, the snap-on part passes through the surface groove of the fastening slot and enters the fastening groove, where the hook engages with the latch, forming a dual mechanical and magnetic lock to prevent accidental detachment.

[0021] During the unhooking process, pull the upper magnetic buckle piece longitudinally in the direction opposite to the hook body's orientation, or pull the flap. The applied pulling force overcomes the magnetic force and the buckle's resistance, causing the buckle to slide within the engagement groove into the clearance space. The hook body disengages from the latch, the magnetic force weakens, and the buckle is pulled directly out of the engagement groove, achieving a sliding unhooking. Alternatively, the engagement groove has a clearance space on the hook back side. Pinch the end of the upper magnetic buckle piece away from the hook body and lift it outwards. The entire upper magnetic buckle piece flips outwards from the lower magnetic buckle piece using the hook back as a fulcrum. The hook body uses the clearance cavity to tilt down and exit the engagement groove, completing a flipping unhooking.

[0022] The magnetic clasp provided by this utility model adopts a combined sliding and flipping unlocking method. It can only be unlocked by sliding or flipping in a specific direction to avoid accidental opening. It can be unlocked with one hand, making it convenient to operate and providing a better user experience. The magnetic attraction provides an initial connection, and the connection between the inverted buckle and the fastening groove enhances the tensile strength, making it more stable than pure magnetic attraction and preventing accidental detachment. The magnet has an automatic adsorption and positioning function, and the inverted buckle and fastening groove can be quickly and accurately fastened by magnetic attraction.

Detailed Implementation

[0045] The core of this utility model is to provide a magnetic snap fastener with multiple unhooking methods, which is convenient to operate and improves the user experience.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] Please refer to Figures 1 to 19 This is a schematic diagram of the structure of a magnetic clasp provided in a specific embodiment of this utility model.

[0048] In one specific embodiment, the magnetic snap provided by this utility model includes an upper magnetic snap piece 3 and a lower magnetic snap piece 4. The outer surfaces of the upper magnetic snap piece 3 and the lower magnetic snap piece 4 are fixedly connected to the cover 2 and the body 1, respectively. The upper magnetic snap piece 3 and the lower magnetic snap piece 4 are respectively provided with magnets 5 that can be magnetically attracted to each other at corresponding positions inside. The inner surface of the upper magnetic snap piece 3 is provided with a snap 31, and the inner surface of the lower magnetic snap piece 4 is provided with a fastening groove 41 that cooperates with the snap 31 to realize the connection between the snap 31 and the fastening groove 41. The fastening groove 41 has a surface groove on the inner surface of the lower magnetic snap piece 4 so that the snap 31 can be fastened to the fastening groove 41 through the surface groove. The snap 31 includes a hook body 33 and a hook back, wherein the hook body 33 faces opposite to the hook back. The fastening groove 41 has a clearance space on the side where the hook back is located so that the upper magnetic snap piece 3 located away from the hook body 33 can be flipped away from the lower magnetic snap piece 4 to realize the snapping.

[0049] Furthermore, the locking groove 41 is designed to release the buckle when the buckle 31 slides in a direction away from the hook body 33.

[0050] In the above structure, the outer surface of the magnetic snap upper piece 3 is fixedly connected to the flap 2, which can be achieved by conventional sewing. The inner surface of the magnetic snap upper piece 3 has a snap fastener 31, one side of which has a hook body 33, and the other side has a hook back, with the hook body 33 facing opposite directions to the hook back. The hook body 33 engages with the snap-fit ​​groove 41 on the magnetic snap lower piece 4 to achieve fastening. An internal magnet 5 is provided, corresponding to the position of the magnet 5 in the magnetic snap lower piece 4, to achieve magnetic attraction.

[0051] The outer surface of the lower magnetic snap piece 4 is fixedly connected to the clasp 1 using conventional sewing. The inner surface of the lower magnetic snap piece 4 has a snap-fit ​​groove 41 to accommodate the inverted snap 31 of the upper magnetic snap piece 3. It also contains a magnet 5, corresponding to the magnet 5 in the upper magnetic snap piece 3, with opposite magnetic poles for attraction. It should be noted that the magnetic attraction between the magnets 5 of the upper magnetic snap piece 3 and the lower magnetic snap piece 4 satisfies the connection strength between the clasp 2 and the clasp 1, achieving connection stability.

[0052] A surface groove is provided on the inner surface of the lower magnetic snap piece 4, allowing the snap fastener 31 to enter or exit the fastening groove 41. When the snap fastener 31 is inserted into the fastening groove 41, the upper magnetic snap piece 3 and the lower magnetic snap piece 4 are fastened together. When the snap fastener 31 is pulled out of the fastening groove 41, the upper magnetic snap piece 3 and the lower magnetic snap piece 4 are unfastened.

[0053] The snap-fit ​​groove 41 is not completely blocked on the back of the hook; instead, it has a sufficiently large cavity reserved, which serves as the clearance space. When you pinch the end of the upper magnetic snap 3 away from the hook body 33 and lift it outwards, the entire upper magnetic snap 3 flips outwards from the lower magnetic snap 4 using the hook back as a fulcrum. The hook body 33 then lowers and exits the snap-fit ​​groove 41 using the clearance cavity. Because of the clearance space, the hook back is not blocked by the groove wall, and the hook tip can slide out of the snap-fit ​​groove 41 to complete the unhooking process. Without the clearance space, the hook back would be blocked by the groove wall and could not be lifted.

[0054] During the fastening process, when the upper magnetic snap 3 and the lower magnetic snap 4 approach each other, the internal magnets 5 attract each other, automatically guiding them to align and fit together, achieving initial positioning. At the same time, the inverted snap 31 passes through the surface groove of the fastening groove 41 and enters the fastening groove 41, and the hook 33 engages with the latch 44 in the fastening groove 41, forming a double lock of mechanical and magnetic force to prevent accidental disengagement.

[0055] During the unblocking process, users can unblock in two ways:

[0056] In the first sliding unlocking method, the user pulls the magnetic buckle plate 3 or the cover vertically in the direction away from the hook body 33 (i.e. the back of the hook body 33). The applied pulling force F1 overcomes the magnetic force and the resistance of the buckle 31. The buckle 31 slides in the fastening groove 41 to the clearance space, the hook body 33 disengages from the latch 44, the magnetic force weakens, and the buckle 31 is pulled directly out of the fastening groove 41, realizing sliding unlocking.

[0057] The second flip unlocking method involves the user pinching the end of the upper magnetic buckle 3 away from the hook body 33 and lifting it outward. The entire upper magnetic buckle 3 flips outward from the lower magnetic buckle 4 with the hook back as the fulcrum. The hook body 33 then moves out of the fastening groove 41 by lowering its head in the clearance cavity, thus completing the flip-type unlocking.

[0058] The magnetic clasp provided by this utility model adopts a combined sliding and flipping unlocking method. It can only be unlocked by sliding or flipping in a specific direction. It is not easy to fall off due to daily collisions and avoids accidental opening. It can be unlocked with one hand, which is convenient and provides a good user experience. It is suitable for scenarios such as bags and clothing that need to be opened and closed frequently. The magnetic attraction provides an initial connection, and the connection between the inverted buckle 31 and the fastening groove 41 enhances the tensile strength, making it more stable than pure magnetic attraction and preventing accidental fall-off. For example, even if the bag is bulging with items, it can still be fastened tightly. The magnet 5 has an automatic adsorption and positioning function. The inverted buckle 31 and the fastening groove 41 can be fastened quickly and accurately through magnetic adsorption.

[0059] Based on the above specific embodiments, the hook back of the buckle 31 is an inclined surface 32, and the fastening groove 41 is provided with a beveled surface 43 that cooperates with the inclined surface 32 to form a clearance space.

[0060] In some embodiments, one side of the inverted buckle 31 forms a hook 33 to engage with the latch 44 of the fastening groove 41. The hook back is oriented in the opposite direction to the hook body 33, and is designed as an inclined surface 32. The surface of the inclined surface 32 forms an acute angle with the inner surface of the upper magnetic buckle piece, and the normal direction of the inclined surface 32 is opposite to the orientation of the hook tip. At the position corresponding to the hook back, the fastening groove 41 is machined with a beveled surface 43 at the same angle as the inclined surface 32. When the upper magnetic buckle piece 3 and the lower magnetic buckle piece 4 are attracted together, the inclined surface 32 and the beveled surface 43 fit together, forming a wedge-shaped clearance space. That is, the hook back and the groove wall are no longer tightly fitted, but a gradually opening gap is left.

[0061] When unhooking, pinch the end of the magnetic snap 3 away from the hook body 33 with your fingers and flip it outward. The inclined surface 32 slides along the oblique cut surface 43, acting as a slide rail. The hook back makes way in the gap, and the hook body 33 is gradually lifted by the oblique component force. The hook tip comes out of the latch 44 of the snap-fit ​​groove 41. The flipping angle does not need to be large. As long as the inclined surface 32 completes the entire length of the oblique cut surface 43, the hook body 33 will be completely disengaged, and the magnetic force will weaken, realizing one-handed flip-type unhooking.

[0062] In summary, the inclined surface 32 and the oblique cut surface 43 not only provide space for movement but also act as guide wedges, transforming the flipping action into a smooth lifting action of the hook body 33, making opening and closing with one hand time-saving and labor-saving.

[0063] Based on the above specific embodiments, at least one side of the fastening groove 41 passes through the side of the magnetic buckle lower piece 4 to form a side groove 42, so that the buckle 31 slides along the side groove 42 to unfasten.

[0064] In some embodiments, at least one sidewall of the fastening groove 41 is directly opened through, and the outer side of the magnetic snap lower piece 4 is opened through to form a side slot 42, turning the closed fastening groove 41 into an open slide, allowing the snap fastener 31 to slide laterally to unlock, providing a side-sliding unlocking path. The side slot 42 can be on the left, the right, or even both sides simultaneously.

[0065] At this point, the hook 33 of the inverted buckle 31 is still stuck in the same latch 44, and there is clearance space between the inclined surface 32 and the oblique cut surface 43 of the fastening groove 41, which can be unhooked by sliding or flipping. However, the inverted buckle 31 can no longer be unhooked only from the surface groove, but can also be unhooked by side sliding.

[0066] The user applies a first thrust F2 to the magnetic buckle plate 3 in the direction parallel to the side slot 42. The buckle 31 moves horizontally along the direction of the side slot 42. The hook 33 slides into the slot 44 and then naturally loses its constraint after reaching the edge of the side slot 42. It slides out laterally from the buckle slot 41, thus achieving horizontal side-sliding unlocking.

[0067] Since the side slot 42 is located on the side, fingers do not need to reach to the bottom of the magnetic snap lower piece 4, nor is there a flipping action. Simply hold the flap 2 with one hand and gently push it to the side. The snap 31 slides out along the side slot 42, and the magnetic attraction weakens instantly, allowing the flap 2 to be opened. This one-handed operation is simple, and it opens with a push, making the snapping smooth. At the same time, it enriches the snapping methods, making snapping more flexible and convenient.

[0068] Based on the above specific embodiments, the upper magnetic snap piece 3 is provided with two inverted snaps 31, which are arranged in the longitudinal direction. The lower magnetic snap piece 4 is provided with two fastening grooves 41 that cooperate with the inverted snaps 31. The side openings 42 of the two fastening grooves 41 are aligned in the same direction.

[0069] In one embodiment, the number of inverted buckles 31 on each magnetic snap plate 3 can be one, two, or more. The setting method for two and more is the same. The following description uses two as an example.

[0070] Two inverted buckles 31 are arranged sequentially along the longitudinal direction, that is, along the length of the upper magnetic buckle 3. The longitudinal arrangement direction of the two inverted buckles 31 is perpendicular to the opening direction of the side groove 42 of the fastening groove 41. Preferably, the center lines of the two inverted buckles 31 coincide, and the direction of the line connecting the center lines is perpendicular to the opening direction of the side groove 42 of the fastening groove 41.

[0071] Correspondingly, the lower magnetic snap piece 4 is provided with two snap grooves 41, which correspond one-to-one with the two inverted snaps 31 of the upper magnetic snap piece 3. That is, the two snap grooves 41 are arranged in the longitudinal direction and their positions correspond to the positions of the two inverted snaps 31 of the upper magnetic snap piece 3.

[0072] The use of double buckles and double snap-fit ​​grooves increases the mechanical connection points between the upper magnetic buckle 3 and the lower magnetic buckle 4, improving the overall connection's firmness and tensile strength. Even if the contents of the bag are bulging, the buckle can still be tightly fastened. The upper magnetic buckle 3 and the lower magnetic buckle 4 are easier to position precisely when connected. Even if there is a slight processing error in a single buckle 31 or snap-fit ​​groove 41, the cooperation between the other buckle 31 and the snap-fit ​​groove 41 can ensure the reliability of the overall connection.

[0073] Meanwhile, the side openings 42 of the two fastening grooves 41 are aligned, meaning that the side openings 42 of the two fastening grooves 41 both face the same side. During sliding release, the two buckles 31 can slide out smoothly along the side openings 42 simultaneously, avoiding jamming or one-sided disengagement and improving the smoothness and reliability of sliding release.

[0074] During the fastening process, when the upper magnetic snap 3 and the lower magnetic snap 4 come close together, the internal magnet 5 generates an attraction force, causing the two to automatically fit together; the two inverted snaps 31 enter the corresponding fastening grooves 41 through the surface slots of the fastening grooves 41 respectively, achieving double mechanical locking.

[0075] During the sliding unlocking process, the magnetic buckle upper piece 3 slides along the side groove 42 of the fastening groove 41; the two inverted buckles 31 slide out simultaneously along the side groove 42, achieving smooth and stable unlocking.

[0076] As can be seen from the above, the magnetic snap fastener, while ensuring the convenience of magnetic adsorption, further improves the reliability of the mechanical connection and the smoothness of the unhooking operation.

[0077] Based on the above specific embodiments, there are two magnetic snaps, which are arranged in parallel in the horizontal direction, and the side slots 42 on the two magnetic snaps are set to the same direction or opposite directions.

[0078] In one embodiment, the gusset body 1 has two or more covers 2 in the width direction, and each cover 2 is provided with a magnetic snap, that is, it has two or more magnetic snaps. The arrangement of the two or more magnetic snaps is similar, and two are used as an example for explanation below.

[0079] The two magnetic snaps are arranged in parallel in the horizontal direction, that is, in parallel in the width direction of the magnetic snaps. The horizontal arrangement direction of the two magnetic snaps is the same as the opening direction of the side slot 42 of their respective snap-fit ​​grooves 41.

[0080] The side slots 42 on the two magnetic snaps can be configured in one of the following two ways:

[0081] In the first case, the side slots 42 on the two magnetic snaps are oriented in the same direction, that is, the side slots 42 of the two magnetic snaps face the same side. At this time, when the cover 2 is pulled along the direction of the side slots 42, the buckles 31 of the two magnetic snaps slide out from the side slots 42 on the same side at the same time.

[0082] The second type has the side slots 42 of the two magnetic snaps facing each other, one to the left and the other to the right, with their openings opposite each other. At this time, two fingers are used to press the two flaps 2 inward together, and the magnetic snaps of the two flaps 2 come closer to each other and slide out from their respective side slots 42.

[0083] Depending on actual usage needs, the orientation of the side slots 42 of the two magnetic snaps can be flexibly selected to achieve different unlocking methods. When the side slots 42 of the two magnetic snaps are in the same orientation, during sliding unlocking, both magnetic snaps can be pushed to slide in the same direction simultaneously, achieving one-handed synchronous unlocking, making the operation more convenient and efficient; when the side slots 42 of the two magnetic snaps are set opposite each other, the user can also apply a second pushing force F3 from both sides with one hand to open the two magnetic snaps synchronously, making the operation smoother and more convenient.

[0084] By using two horizontally arranged magnetic snaps, the number of connection points is doubled compared to a single magnetic snap, improving the overall tensile strength and stability of the structure. Furthermore, the relationship between the 42-degree angle of the side slots and the arrangement direction is clearly defined, further enhancing the connection strength, ease of operation, and assembly precision of the magnetic snaps. This design not only enhances the product's practicality and reliability but also provides a better user experience. It is particularly suitable for applications requiring resistance to significant external forces or frequent opening and closing, such as wearable devices, clothing, and bags.

[0085] Based on the above specific embodiments, the fastening groove 41 is a through groove that extends through both sides of the magnetic snap lower piece 4.

[0086] In one embodiment, the fastening groove 41 not only has a surface groove on the inner surface of the magnetic snap lower piece 4 for the snap fastener 31 to be inserted or pulled out, but its left and right sides are also completely through the sides of the magnetic snap lower piece 4, forming a through groove. That is, the fastening groove 41 forms a transverse through hole or through channel on the magnetic snap lower piece 4, and the snap fastener 31 can slide in or out from either side to achieve bidirectional unfastening.

[0087] Because the locking groove 41 is open on both sides, the undercut 31 can slide out from either side, no longer limited to a single direction. Users can choose a more suitable unhooking direction according to their actual usage habits or space constraints, meeting different operating habits and usage needs, and improving the flexibility and convenience of unhooking. The through-groove structure makes the fit between the undercut 31 and the locking groove 41 smoother, reducing possible jamming or obstruction during unhooking, and further improving the smoothness and stability of the unhooking operation. The through-groove structure is relatively simple, which facilitates mold design and processing, helps to reduce production costs and improve production efficiency.

[0088] When used in conjunction with the aforementioned double-inverted and double-locking groove structure, the through groove can further enhance the overall stability and ease of unlocking.

[0089] When used in conjunction with a structure in which two magnetic snaps are arranged horizontally, the through slot allows for more flexible selection of the sliding and unhooking direction, such as sliding on both sides simultaneously or sliding on one side.

[0090] Based on the above specific embodiments, the inverted buckle 31 is divided into a hook buckle 311 and a straight buckle 312. The hook body 33 of the hook buckle 311 includes a vertically arranged vertical surface and a horizontal surface to form an L-shaped structure. The hook body 33 of the straight buckle 312 is an inclined surface parallel to the inclined surface 32.

[0091] In some embodiments, the buckle 31 includes two fasteners with different profiles, namely hook buckle 311 and straight buckle 312.

[0092] The hook 311 has a hook at its front end. Its hook body 33 consists of a vertical surface and a horizontal surface perpendicularly connected to form a rigid L-shaped hook angle. The back of the hook is an inclined surface 32. The structure is simple, reliable, and easy to manufacture. The vertical surface is set along the vertical direction and limits the locking of the side wall of the fastening groove 41, providing lateral locking force to prevent the upper magnetic buckle 3 from slipping laterally. The horizontal surface is set along the horizontal direction to form a hook tip. The hook tip faces the opposite direction to the flip end and is used to hook the latch in the fastening groove 41, bearing the main locking force and providing longitudinal locking force to prevent the upper magnetic buckle 3 and the lower magnetic buckle 4 from being accidentally pulled apart.

[0093] The hook 311 combines lateral locking and longitudinal locking to form a robust mechanical locking structure, which improves the locking force between the hook 311 and the locking groove 41 and enhances the stability of the locking.

[0094] The front end of the straight buckle 312 is flat and without a hook. Its hook body 33 is no longer L-shaped, but is made into a sloping surface parallel to the inclined surface 32. This sloping surface has no hook tip and is used to press against the inclined surface 43 in the fastening groove 41, serving as a guide and positioning function. When the magnetic buckle upper piece 3 is lifted or fastened, the straight buckle 312 slides along the inclined surface 43 without jamming, reducing jamming and making the sliding and flipping movements smoother. At the same time, the sloping surface cooperates with the inner wall of the fastening groove 41 to provide a certain locking effect.

[0095] Based on the above specific embodiments, among the two inverted buckles 31 of the magnetic buckle upper piece 3, the one closer to the flip end is a straight buckle 312, and the one farther away from the flip end is a hook buckle 311. The angle of inclination of the inclined surface 32 of the hook buckle 311 and the straight buckle 312 is the same.

[0096] In some embodiments, there are two snaps 31 on the magnetic snap plate 3, one hook snap 311 and one straight snap 312. The hook snap 311 and the straight snap 312 are arranged in a line along the longitudinal direction. The straight snap 312 is located on the side closer to the flip end, that is, the end that is lifted by the finger, while the hook snap 311 is located on the side away from the flip end.

[0097] The straight snap 312, located immediately next to the flip end, is a flat-top snap with only an inclined surface 32 and no hook tip. When fastening, the straight snap 312 first contacts the lower magnetic snap piece 4, utilizing the dual guiding effect of the inclined surface 32 and the beveled surface for smooth insertion. When unfastening, it provides a fulcrum and clearance for the upper magnetic snap piece 3, allowing the finger to slide smoothly along the beveled surface 43 without getting stuck. The inclined surface 32 and the beveled surface reduce resistance, improving the smoothness and accuracy of fastening and unfastening.

[0098] The hook 311, positioned away from the flip end, is an L-shaped clasp with a hook. When engaged, the hook 311 forms a secure mechanical lock with the engagement groove 41, effectively locking the lower piece 4 of the magnetic clasp. It withstands tension and has strong resistance to pull-out, preventing the magnetic clasp from accidentally detaching when subjected to external force. To unfasten, simply slide or pull in a specific direction to easily release the lock; the operation is simple and convenient.

[0099] With this arrangement, the force of lifting the magnetic snap upper piece 3 first acts on the straight snap 312. When the magnetic snap upper piece 3 is lifted to a certain angle, the hook 311 will then disengage, achieving the sequence of guidance followed by disengagement. It can be opened with a single hand.

[0100] This process ensures that hook 311 can be unhooked smoothly, while avoiding additional resistance from hook 312 and preventing one-sided jamming.

[0101] Furthermore, the angles of the inclined surfaces 32 of the hook 311 and the straight buckle 312 are the same. When the upper piece 3 of the magnetic buckle is lifted, the inclined surface 32 of the straight buckle 312 slides against the beveled surface 43 first, and the inclined surface 32 of the hook 311 slides synchronously thereafter. The hook 311 and the straight buckle 312 are lifted synchronously, and the hook tip is gradually pushed up by the beveled surface 43, and finally disengages from the latch 44, achieving smooth one-handed unfastening.

[0102] Similarly, it provides consistent sliding guidance during the fastening process, ensuring that the two fastening points enter the fastening groove 41 simultaneously, avoiding one-sided jamming or misalignment, and improving the smoothness and accuracy of fastening.

[0103] Based on the above specific embodiments, the hook body 33 of the straight buckle 312 has a vertical surface at its base. This vertical surface connects with the inclined surface to form a folded structure, which is a non-continuous plane but a composite surface with a bend. This folded structure forms a double contact surface. The vertical surface can serve as a stop surface, creating a locking effect during fastening to prevent the straight buckle 312 from accidentally slipping off, providing additional mechanical restraint, and enhancing the stability after fastening.

[0104] Meanwhile, the vertical plane is shorter than the inclined plane. The vertical plane is shorter and the inclined plane is longer. The straight buckle 312 mainly plays a guiding role to ensure a smoother fastening and unfastening process.

[0105] The vertical surface of the straight buckle 312 is connected to the upper piece 3 of the magnetic buckle, forming the root of the straight buckle 312. The width of the straight buckle 312 on the vertical surface is greater than its width on the inclined surface, that is, the width of the root of the straight buckle 312 is greater than the width of the end. The wider root improves the structural strength and load-bearing capacity, and prevents the straight buckle 312 from deforming or breaking under stress.

[0106] In another preferred embodiment, the inclined surface of the straight buckle 312 is not parallel to its inclined surface 32. The straight buckle 312 has a tapered structure that gradually narrows from the root to the end. The end is narrower, which reduces the insertion resistance and makes the insertion smoother.

[0107] Based on the above specific embodiments, the outer surfaces of the upper magnetic snap piece 3 and the lower magnetic snap piece 4 are respectively provided with mounting holes. These mounting holes are used to accommodate the magnet 5, achieving the magnetic attraction function. The mounting holes and the magnet 5 are matched in shape, typically circular or square, with the hole size slightly smaller than the outer diameter of the magnet 5 to achieve an interference fit. The magnet 5 is embedded into the mounting hole by pressing or heat fitting, and the interference fit between the magnet 5 and the mounting hole achieves a fixed connection, preventing the magnet 5 from loosening or falling off during use, and ensuring a stable and reliable magnetic attraction effect between the upper magnetic snap piece 3 and the lower magnetic snap piece 4. At the same time, the interference fit method simplifies the assembly process of the magnet 5, resulting in a simple structure and high assembly efficiency.
