Description

Technical Field

[0001] This utility model relates to the field of accessories technology, specifically to a magnetic buckle. Background Technology

[0002] When connecting components in bags, clothing, helmets, seat belts, keychains, and other items, clips or magnetic buckles are generally used. Existing clips often use a pressing or plugging method for engagement. During unlocking and locking, these clips often require a specific angle to smoothly separate or connect components, making the process cumbersome, impractical, and resulting in a poor user experience. Existing magnetic buckles rely on the magnetic attraction between magnetic components to connect and separate multiple components. However, during connection, relying solely on the magnetic attraction between components makes them prone to slippage under significant external force, potentially leading to loss of items or even endangering user safety. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a magnetic buckle that has the advantages of self-locking, flexibility and speed, convenient unlocking, and secure locking.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a magnetic buckle, comprising:

[0005] The first buckle body has a first groove at its lower end;

[0009] The snap-fit ​​component includes: a snap-fit ​​component body rotatably mounted on the first buckle body, a pressing portion disposed on the snap-fit ​​component body and away from the first groove end, and a snap-fit ​​portion disposed on the snap-fit ​​component body and close to the first groove end.

[0010] An elastic reset element is placed between the pressing part and the first buckle body;

[0011] When the pressing part is pressed, the elastic reset member is in a compressed state, and the snap-fit ​​part rotates outward; the second snap body is pulled away from the first snap body, so that the pulling force on the second snap body is greater than the mutual attraction between the first magnetic member and the second magnetic member, so that the first snap body and the second snap body are separated;

[0012] When the second buckle moves toward the first buckle, and with the magnetic assistance of the first and second magnetic components, the second buckle opens the latching portion so that the latching portion rotates outward, and the second buckle is placed into the first groove. Under the action of the elastic reset component, the latching portion resets to latch the second buckle.

[0013] In a further embodiment of this invention, two snap-fit ​​components are provided.

[0014] The present invention further provides that the snap-fit ​​portion facing the second buckle body has a first guide slope that rises upward from left to right, and the side of the second buckle body facing the first groove has a second guide slope that is connected to the top surface of the second buckle body facing the first groove and is inclined outward, and a third guide slope that is connected to the second guide slope and is inclined outward on one side; the first guide slope, the second guide slope and the third guide slope cooperate to facilitate the second buckle body being placed into the first groove.

[0015] The present invention further comprises that the snap-fit ​​body is rotatably assembled on the first buckle body via a rotating assembly; the rotating assembly includes: a pivot seat disposed on the side of the snap-fit ​​body facing the first buckle body, a first mounting groove opened on the side of the first buckle body facing the snap-fit ​​body and into which the pivot seat is inserted, a pivot mounting hole opened on the side of the first buckle body facing the snap-fit ​​body and communicating with the first mounting groove, and a pivot passing through the pivot mounting hole and the pivot seat.

[0016] The present invention further provides that the pressing part has an outwardly protruding part on the side facing away from the first buckle body.

[0017] The present invention further provides that the pressing part has a second mounting groove recessed in a direction away from the first buckle body on the side facing the first buckle body, and the first buckle body has a third mounting groove recessed in a direction away from the pressing part on the side facing the pressing part, which corresponds to the position of the second mounting groove; the second mounting groove and the third mounting groove cooperate to limit the installation position of the elastic reset member.

[0018] The present invention is further provided that the first buckle body is provided with a snap-fit ​​mounting groove for mounting the snap-fit ​​component.

[0019] The present invention further provides that the mounting groove of the snap-fit ​​component has a through hole that connects to the first groove at the position corresponding to the snap-fit ​​part, so that the snap-fit ​​part can extend into the first groove when it is reset.

[0020] The present invention further provides that the second buckle body has an annular groove on its periphery facing one end of the first groove, which engages with the snap-fit ​​part.

[0021] The present invention further provides that the second buckle body has a second groove recessed in a direction away from the first groove at one end facing the first groove, and the second groove is used to install the second magnetic component.

[0022] The beneficial effects of this utility model after adopting the above technical solution are as follows: In this utility model, simply pressing the pressing part causes the locking part located at the other end of the locking body to rotate outward, thereby unlocking the locking part from the second buckle. At this time, pulling the second buckle away from the first buckle makes the pulling force on the second buckle greater than the mutual attraction between the first and second magnetic components, causing the first buckle to separate from the second buckle. The overall unlocking process is convenient and quick. After unlocking the locking part from the second buckle, there is still a mutual attraction between the second buckle and the first buckle, preventing the locking part from rotating accidentally and causing the second buckle to fall off accidentally. When the second buckle moves towards the first buckle, and with the magnetic assistance of the first and second magnetic components, the second buckle opens the locking part, causing the locking part to rotate outward. The second buckle is placed into the first groove, and under the action of the elastic reset component, the locking part resets to lock the second buckle. The self-locking is flexible, and the first and second buckles can be fastened without a specific angle, making the operation convenient and quick. Furthermore, after the first and second buckles are engaged, the locking part resets to lock the second buckle, increasing the firmness between the first and second buckles and ensuring the stability of the lock between them.

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0037] This embodiment relates to a magnetic clasp, as shown in the reference... Figures 1-3The fastener includes: a first fastener 100, a second fastener 200, a first magnetic 310, a second magnetic 320, a snap-fit ​​component 400, and an elastic reset component 500. The first fastener 100 has a first groove 110 at its lower end; one end of the second fastener 200 is detachably fitted into the first groove 110; the first magnetic 310 is disposed within the first groove 110; and the second magnetic 320 is disposed at the end of the second fastener 200 facing the first groove 110. The first magnetic 310 and the second magnetic 320 cooperate to allow the first fastener 100 and the second fastener 200 to be fastened together under the mutual attraction of the first magnetic 310 and the second magnetic 320. The snap-fit ​​component 400 includes: a snap-fit ​​component body 410, a pressing part 420, and a snap-fit ​​part 430. The snap-fit ​​body 410 is rotatably mounted on the first buckle body 100; the pressing part 420 is disposed on the snap-fit ​​body 410 and away from the end of the first groove 110; the snap-fit ​​part 430 is disposed on the snap-fit ​​body 410 and close to the end of the first groove 110. The elastic reset part 500 is placed between the pressing part 420 and the first buckle body 100. When the pressing part 420 is not pressed, one end of the elastic reset member 500 abuts against the pressing part 420 and the other end abuts against the first buckle body 100. Since both the snap-fit ​​part 430 and the pressing part 420 are located on the snap-fit ​​body 410, and the pressing part 420 is located on the snap-fit ​​body 410 and away from the first groove 110, while the snap-fit ​​part 430 is located on the snap-fit ​​body 410 and close to the first groove 110, the snap-fit ​​part 430 extends into the first groove 110 to snap the second buckle body 200 so that the first buckle body 100 and the second buckle body 200 are locked together.

[0038] Reference Figures 4-6 The operation to unlock the first buckle 100 and the second buckle 200 is as follows: Press the pressing part 420, the snap fastener body 410 rotates, the pressing part 420 squeezes the elastic reset member 500, so that it is in a compressed state, and the snap fastener part 430 located at the other end of the snap fastener 400 rotates outward; the user pulls the second buckle 200 in a direction away from the first buckle 100, so that the pulling force on the second buckle 200 is greater than the mutual attraction between the first magnetic member 310 and the second magnetic member 320, so that the first buckle 100 and the second buckle 200 can be separated.

[0039] The entire unlocking process is convenient and quick. Simply press the pressing part 420 and pull the second buckle 200 outward to separate the first buckle 100 from the second buckle 200. The operation is simple. After the unlocking latch 430 engages with the second buckle 200, there is still mutual attraction between the second buckle 200 and the first buckle 100, preventing the latch 430 from rotating accidentally and causing the second buckle 200 to fall off accidentally.

[0040] Reference Figures 1-3The operation of locking the first buckle 100 and the second buckle 200 is as follows: The user moves the second buckle 200 toward the first buckle 100, and with the magnetic assistance of the first magnetic suction member 310 and the second magnetic suction member 320, the second buckle 200 opens the locking part 430. At this time, the locking part 430 rotates outward, the elastic reset member 500 is in a compressed state, and the second buckle 200 is placed into the first groove 110. Under the mutual attraction of the first magnetic suction member 310 and the second magnetic suction member 320, the first buckle 100 and the second buckle 200 are fastened. Under the action of the elastic reset member 500, the locking part 430 is reset to lock the second buckle 200, further locking the second buckle 200 and the first buckle 100.

[0041] The self-locking operation is flexible, allowing the second buckle 200 to be placed into the first groove 110 without requiring a specific angle, thus fastening the first buckle 100 and the second buckle 200 together quickly and easily. After the first buckle 100 and the second buckle 200 are fastened together, the locking member 400 resets to lock the second buckle 200, further securing the first buckle 100 and the second buckle 200 together and ensuring the firmness of the fastening.

[0042] It should be noted that both the first magnetic attractor 310 and the second magnetic attractor 320 can be magnets, or one can be made of a magnetic material and the other of a metallic material. It is sufficient that the first magnetic attractor 310 and the second magnetic attractor 320 can generate a mutual attractive force, including a magnetic attraction. In this embodiment, both the first magnetic attractor 310 and the second magnetic attractor 320 are magnets. In this embodiment, the elastic reset member 500 is a spring. In some embodiments, the elastic reset member 500 can also be other objects that can reset after the external force is removed.

[0043] In this embodiment, two snap-fit ​​members 400 are provided to enhance the locking effect on the second buckle 200 and prevent the second buckle 200 from accidentally falling off. Correspondingly, two snap-fit ​​member bodies 410 are also provided, as are two pressing portions 420 and two snap-fit ​​portions 430. The number of snap-fit ​​member bodies 410, pressing portions 420, and snap-fit ​​portions 430 corresponds to the number of snap-fit ​​members 400. In some embodiments, only one snap-fit ​​member 400 may be provided.

[0044] In this embodiment, refer to Figure 7The first buckle body 100 has a snap-fit ​​mounting slot 120 for mounting the snap-fit ​​component 400. Providing additional accommodating space on the first buckle body 100 for mounting the snap-fit ​​component 400 ensures both the overall aesthetics and structural compactness of the magnetic buckle, while also further protecting the snap-fit ​​component 400 from detachment from the first buckle body 100 due to excessive external force. The number of snap-fit ​​mounting slots 120 corresponds to the number of snap-fit ​​components 400. In this embodiment, there are two snap-fit ​​components 400, therefore, there are also two snap-fit ​​mounting slots 120. In some embodiments, there may be only one snap-fit ​​mounting slot 120.

[0045] Furthermore, referring to Figure 7 The mounting groove 120 of the snap fastener has a through hole 140 that connects to the first groove 110 at the position corresponding to the snap fastener 430, so that when the snap fastener 430 is reset, it can extend into the first groove 110 to snap the second buckle body 200. The through hole 140 plays a certain guiding and limiting role in the snap fastener 430 snapping the second buckle body 200.

[0046] In this embodiment, a first hanging hole 150 is provided at one end of the first buckle body 100 away from the first groove 110, for users to hang items such as keys and ornaments.

[0047] In this embodiment, refer to Figure 3 as well as Figures 9-10 The snap-fit ​​portion 430 has a first guide slope 431 that rises upwards from left to right on the side facing the second buckle 200. The side of the second buckle 200 facing the first groove 110 has a second guide slope 230 and a third guide slope 240. The second guide slope 230 connects to the top surface of the second buckle 200 facing the first groove 110 and slopes outwards; the third guide slope 240 connects to the second guide slope 230 on one side and slopes outwards. The first guide slope 431, the second guide slope 230, and the third guide slope 240 work together to facilitate the insertion of the second buckle 200 into the first groove 110, reducing friction and resistance during insertion and making the self-locking operation smoother. In some embodiments, the end of the second buckle 200 facing the first groove 110 can be rounded to reduce friction with other components.

[0048] In this embodiment, refer to Figure 7The snap-fit ​​body 410 is rotatably mounted on the first buckle 100 via a rotating assembly. The rotating assembly includes a pivot seat 610, a first mounting groove 620, a pivot mounting hole 630, and a pivot 640. The pivot seat 610 is located on the side of the snap-fit ​​body 410 facing the first buckle 100; the first mounting groove 620 is formed on the side of the first buckle 100 facing the snap-fit ​​body 410 and allows the pivot seat 610 to be inserted; the pivot mounting hole 630 is formed on the side of the first buckle 100 facing the snap-fit ​​body 410 and communicates with the first mounting groove 620; the pivot 640 passes through the pivot mounting hole 630 and the pivot seat 610. The pivot seat 610, the first mounting groove 620, the pivot mounting hole 630, and the pivot 640 cooperate to allow the pivot seat 610 to rotate around the pivot 640 within the first mounting groove 620, thereby causing the snap-fit ​​body 410 to rotate relative to the first buckle 100. In this embodiment, specifically, the first mounting groove 620 is placed within the snap-fit ​​mounting groove 120, and the pivot mounting hole 630 is formed on the side of the first buckle body 100 facing the snap-fit ​​body 410, located on the periphery of the first mounting groove 620 and communicating with the first mounting groove 620. The two ends of the pivot 640 are placed within the pivot mounting holes 630 and pass through the pivot seat 610. In this embodiment, there are two snap-fit ​​bodies 410, two pivot seats 610, two pivots 640, two first mounting grooves 620, and four pivot mounting holes 630. In some embodiments, the pivot seats 610, pivots 640, first mounting grooves 620, and pivot mounting holes 630 are adaptively adjusted according to the number of snap-fit ​​bodies 410. In this embodiment, the magnetic buckle also includes a cover for fixing the pivot 640 and fasteners for fixing the cover to the first buckle body 100. The cover and fasteners prevent the pivot 640 from falling off. In this embodiment, the fastener is a screw. In some embodiments, the fastener may also be other components used to lock the cover.

[0049] In this embodiment, refer to Figure 7 as well as Figure 9 The pressing part 420 has an outwardly protruding protrusion 440 on the side facing away from the first buckle body 100. The protrusion 440 makes it easier for the user to apply force and quickly find the operation point to unlock the first buckle body 100 and the second buckle body 200, thereby improving the accuracy and comfort of the user's operation.

[0050] Furthermore, referring to Figures 7-9The pressing part 420 has a second mounting groove 421 recessed in a direction away from the first buckle body 100 on the side facing the pressing part 420. The first buckle body 100 has a third mounting groove 130 recessed in a direction away from the pressing part 420 on the side facing the pressing part 420, corresponding to the position of the second mounting groove 421. The second mounting groove 421 and the third mounting groove 130 cooperate to restrict the installation position of the elastic reset member 500, preventing the elastic reset member 500 from falling out. Simultaneously, the second mounting groove 421 and the third mounting groove 130 provide space for the elastic reset member 500 to extend and retract. Specifically, one end of the elastic reset member 500 abuts against the inner bottom surface of the second mounting groove 421, and the other end abuts against the inner bottom surface of the third mounting groove 130. The third mounting groove 130 is located within the snap-fit ​​mounting groove 120. In some embodiments, this magnetic buckle may only have the second mounting groove 421 or only the third mounting groove 130.

[0051] In this embodiment, refer to Figure 7 as well as Figure 10 The second buckle body 200 has an annular groove 220 on its circumference facing the first groove 110, which engages with the locking part 430. This increases the flexibility of the magnetic buckle's self-locking mechanism, allowing the user to engage the annular groove 220 with the locking part 430 without a specific angle, simplifying the self-locking process. Furthermore, the design of the annular groove 220 increases the lifespan of the magnetic buckle and improves the reliability of the connection. It avoids excessive stress concentration in the groove design during frequent engagement of the locking part 430 and the groove, which could lead to wear or deformation of the groove and reduce the stability of the connection between the locking part 430 and the groove.

[0052] Furthermore, referring to Figure 7 as well as Figure 10 The second buckle body 200 has a second groove 210 recessed at one end facing the first groove 110, which is used to install the second magnetic component 320 and prevent it from falling off. In this embodiment, the second buckle body 200 has a second hanging hole 250 at one end away from the second groove 210 for users to hang keys, ornaments, and other items.

[0053] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
