[0002] Magnetic snaps are commonly used to connect two components, such as fasteners for shoes, bags, clothing, protective gear, and hats, offering convenience and a longer lifespan compared to traditional Velcro. However, existing magnetic snaps are not ideal in terms of connection performance. Stable connections are often complex and costly, while simpler designs are usually unreliable, especially under frequent opening and closing or impact, where the connection can loosen, causing components to detach, resulting in inconvenience and even safety hazards. Furthermore, they only offer one connection method and cannot adjust the tightness as needed. Therefore, further improvements to the structure of magnetic snaps are necessary. Utility Model Content

[0003] In view of this, the present invention provides a magnetic adjustment buckle and related product, which addresses the problems of the prior art by designing a male buckle with magnetic attraction and adjustable position that is inserted into the female buckle for locking, thereby solving the existing technical problems.

[0053] First direction A, second direction B, female buckle 10, receiving cavity 11, first side wall 111, second side wall 112, protruding edge 1121, first limiting part 1122, first magnet 12, male buckle 20, insertion part 21, second limiting part 211, second magnet 22, male buckle mounting plate 30, mounting hole 31, decorative part 40, third magnet 41, bendable fixing piece 42, and product body 50. Detailed Implementation

[0054] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0055] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0056] To simplify the structure of the magnetic snap-locking mechanism, achieve multi-level adjustment, and facilitate operation, the specific details of this utility model are as follows.

[0057] Combination Figures 1 to 7 As shown, an embodiment of this utility model is a magnetic adjustment buckle, which, importantly, includes a female buckle 10 and a male buckle 20;

[0058] The upper side plane of the female buckle 10 is provided with at least two receiving cavities 11 in sequence along the first direction A. The receiving cavity 11 is provided with a first side wall 111 and a second side wall 112 opposite to the first side wall 111 in sequence along the first direction A. The upper part of the second side wall 112 is provided with a protruding edge 1121 in the opposite direction of the first direction A. A first limiting part 1122 is formed on the lower side of the protruding edge 1121 of the second side wall 112. A first magnet 12 is fixedly provided at the bottom of the upper side plane of the female buckle 10. The first magnet 12 is located outside the receiving cavity 11.

[0059] Of course, the receiving cavity 11 can be set in multiple rows, with at least two receiving cavities 11 arranged sequentially along the first direction A in each row. Generally, it is set in two rows, which does not occupy much space and has good fastening stability.

[0060] The male buckle 20 has an insertion part 21 on its lower side plane, which corresponds to the insertion cavity 11. The insertion part 21 has a second limiting part 211 corresponding to the first limiting part 1122. The second limiting part 211 is a hook corresponding to the first limiting part 1122 and can be inserted into the first limiting part 1122. A second magnet 22 corresponding to the first magnet 12 is fixedly provided on the upper part of the lower side plane of the male buckle 20. The second magnet 22 and the first magnet 12 are directly attracted along the second direction B. The bottom surface of the second magnet 22 is directly magnetically attracted to the top surface of the first magnet 12. Here, there can be one insertion part 21, or it can correspond to the number of cavities 11, or there can be more than the number of cavities 11, which can be set according to the needs of tightness adjustment.

[0061] The first direction A is the direction in which the male buckle 20 is pulled when the female buckle 10 and the male buckle 20 are fastened together; the second direction B is the direction perpendicular to the first direction A.

[0062] like Figure 8 As shown, when using the magnetic adjustment buckle of this utility model, when the user needs to fasten it, the male buckle 20 is aligned with the female buckle 10. The male buckle 20 is attracted by the second magnet 22 and the first magnet 12 along the second direction B. The insertion part 21 is inserted into the receiving cavity 11 to complete the fastening. During use, the male buckle 20 has a pulling force along the first direction A. The second limiting part 211 of the male buckle 20 is locked by the first limiting part 1122 along the first direction A.

[0063] like Figure 12As shown, when the user needs to unfasten the buckle, he / she pulls in the opposite direction of the first direction A and simultaneously pulls in the opposite direction of the second direction B to detach the male buckle 20 from the female buckle 10.

[0064] like Figures 8 to 11 As shown, when a user needs to adjust different buckle positions to achieve tightness adjustment, the male buckle 20 insertion part 21 can be inserted into different receiving cavities 11 on the first direction A to adjust different fastening positions, thereby achieving different distances of male buckle 20 fastening.

[0065] The main feature of this invention is that the female buckle 10 is provided with at least two receiving cavities 11 along the first direction A, and the male buckle 20 is designed with an insertion part 21 corresponding to be inserted into the receiving cavity 11. When it needs to be fastened, the male buckle 20 is attracted to the female buckle 10 by the second magnet 22 facing the first magnet 12, and the insertion part 21 is inserted into the receiving cavity 11 to complete the fastening. During use, the male buckle 20 has a pulling force along the pulling direction, and the second limiting part 211 of the male buckle 20 is locked by the first limiting part 1122 along the pulling direction. When it needs to be unfastened, it can be pulled in the opposite direction of the first direction A and simultaneously pulled in the opposite direction of the second direction B to release the male buckle 20 from the female buckle 10. Different fastening positions can be adjusted by inserting the insertion part 21 of the male buckle 20 into different receiving cavities 11 in the first direction A. The magnetic adjustment buckle designed in this way has a simple structure, is easy to process, has a stable fastening, a reliable connection, and is easy to adjust, which is more conducive to the promotion and use of the product.

[0066] More specifically, in some embodiments, the female buckle 10 and male buckle 20 are made of rigid or flexible materials. Rigid materials are less prone to elastic deformation, resulting in more stable locking; flexible materials allow for better adhesion to the surface of the product. Different materials can be selected depending on the application scenario. The receiving cavity 11 and the female buckle 10 are integrally formed, and the material is the same as the female buckle 10; the insertion part 21 and the male buckle 20 are also integrally formed, and the material is the same as the male buckle 20. Alternatively, the female buckle 10 can be made of a rigid material, and the male buckle 20 can be made of a flexible material. The specific design can be tailored to the application scenario to better adapt to the product's use of this magnetic adjustment buckle.

[0067] More specifically, in some embodiments, such as Figure 3 As shown, in order to adjust the locking position of the male fastener, there are one or more first magnets 12, which are sequentially distributed on the outer side of the receiving cavity 11 along the first direction A; there are one or more second magnets 22, which are attracted to the first magnets 12 along the second direction B.

[0068] By adjusting the second magnet 22 to magnetically attract the first magnet 12 at different positions (in the case of a single magnet) or the first magnet 12 at different positions (in the case of multiple magnets), the insertion part 21 of the male buckle 20 is adjusted to be inserted into different receiving cavities 11 in the first direction A, thereby adjusting the male buckle 20 to different fastening positions along the first direction A;

[0069] In this design, the number of first magnets 12 of the female buckle 10 is one or more and they are sequentially distributed on the outer side of one side of the receiving cavity along the first direction. By adjusting the second magnet 22 to magnetically attract the first magnet 12 at different positions (in the case of a single magnet) or the first magnet 12 at different positions (in the case of multiple magnets), the insertion part 21 of the male buckle 20 is adjusted to be inserted into different receiving cavities 11. This allows for adjustment of the different fastening positions of the male buckle 20 along the pulling direction, thereby adjusting the tightness during use. The adjustment method is simple and convenient, providing a better user experience. Moreover, according to the adjustment needs, more first magnets 12 can be set, and more receiving cavities 11 can be set along the pulling direction of the male buckle 20, achieving a wider range of tightness adjustment.

[0070] Specifically, in some embodiments, the first magnet 12 is a magnet and the second magnet 22 is a magnetically conductive metal; or the first magnet 12 is a magnetically conductive metal and the second magnet 22 is a magnet; or the first magnet 12 is a magnet and the second magnet 22 is a magnet. Typically, to ensure the magnetic attraction force, strong magnetic permanent magnets are used at both the top and bottom, providing a strong magnetic attraction force and a more stable fastening.

[0071] It should be noted that in this embodiment, the first magnet 12 and the second magnet 22 are both magnets. This is just one implementation method. As long as the magnets are strong enough, various implementation methods are possible as long as the attraction force between the male buckle 20 and the female buckle 10 can be guaranteed. These include different position settings and different magnetic pole directions.

[0072] Furthermore, in some embodiments, such as Figure 5 As shown, to allow the insertion part 21 to be inserted more smoothly into the receiving cavity 11, the first sidewall 111 is an inclined surface that slopes from top to bottom along the first direction A. This guides the insertion part 21 to slide into the receiving cavity 11, making it easier for the user to insert without precise alignment. Furthermore, by setting the distance between the lowest point of the first sidewall 111 and the first limiting part 1122, the second limiting part 211 at the bottom of the insertion part 21 can be directly inserted into the first limiting part 1122 after the insertion part 21 is inserted along the first sidewall 111 to the bottom, thus completing the locking structure's engagement.

[0073] Furthermore, in some embodiments, such as Figure 13As shown, in order to make it easier to use the magnetic adjustment buckle in this patent, a male buckle mounting plate 30 is provided on the outside of the male buckle 20. The male buckle mounting plate 30 is provided with mounting holes 31 corresponding to the installation of the male buckle 20. When using it, the male buckle mounting plate 30 can be fixed directly without setting the mounting position of the male buckle 20. This makes it convenient to install and assemble the magnetic adjustment buckle of this utility model.

[0074] It is worth noting that the male buckle mounting plate 30 can be made of plastic, webbing, belt, fabric, or silicone. The variety of materials is designed to facilitate the installation and application of the magnetic adjustment buckle of this invention. The shape and material of the male buckle mounting plate 30 can be designed according to actual needs, facilitating the application and promotion of the magnetic adjustment buckle of this invention. For example, in this embodiment, when used for fabric products such as shoes, clothing, and bags, webbing or fabric can be selected. In this embodiment, when used for non-fabric products such as infant products, medical protective gear, and pet supplies, other materials can be selected.

[0075] Furthermore, in some embodiments, such as Figure 14 and Figure 15 As shown, to facilitate manufacturers or users in replacing different decorative or logo accessories according to their personalized needs, a decorative piece 40 is also provided on the upper side of the male buckle 20. A third magnet 41 corresponding to the second magnet 22 is fixedly installed on the lower side of the decorative piece 40. The decorative piece 40 is attracted to the second magnet 22 along the second direction B and is thus mounted on the upper side of the male buckle 20. This design, with the decorative piece 40 magnetically attached to the upper side of the male buckle 20, simplifies assembly and allows manufacturers or users to easily replace different decorative designs or logo accessories according to their personalized needs. With sufficient magnetic strength, no other fixing structure is required, and users can even DIY various different designs. The magnetic method better meets the needs of this scenario, resulting in a better user experience.

[0076] Furthermore, in some embodiments, such as Figure 14 As shown, in order to better secure the decorative piece 40, the lower side of the decorative piece 40 is also fixed to the upper side of the male buckle 20 by means of fixing pieces, buckles, hooks, sewing or adhesive. The magnetic method cannot guarantee that the decorative piece 40 will not fall off. At this time, it is necessary to design a more advanced reinforcement method. Here, various methods such as fixing pieces, buckles, hooks, sewing or adhesive can be used to further reinforce the decorative piece 40 and prevent the decorative piece 40 from falling off.

[0077] More specifically, such as Figure 15As shown, in one embodiment of the above method, the lower fixing piece of the decorative part 40 is a bendable fixing piece 42 located at both ends. Both the male buckle 20 and the male buckle mounting plate 30 have corresponding fixing holes through which the bendable fixing piece 42 passes. The bendable fixing piece 42 passes through the fixing holes of the male buckle 20 and the male buckle mounting plate 30 in sequence and then bends to one side to fix the decorative part 40. This simplifies the assembly operation and makes the decorative part 40 more securely fixed. Of course, this is only one implementation method in this embodiment. Other fixing methods such as snap fasteners, hooks, stitching, or adhesive are also applicable. The specific fixing method can be selected according to actual needs; other fixing methods will not be described in detail here.

[0078] Combination Figures 16 to 26 As shown, this application also provides an article with a magnetic adjustment buckle, which includes an article body 50 and the magnetic adjustment buckle described in any of the above claims. The article body 50 has a first side and a second side that need to be opened and closed. The female buckle 10 of the magnetic adjustment buckle is disposed on the first side, and the male buckle 20 of the magnetic adjustment buckle is disposed on the second side directly or through a male buckle mounting plate 30. The first side of the article body 50 that needs to be opened and closed is magnetically fastened to the female buckle 10 on the second side by the male buckle 20 of the magnetic adjustment buckle.

[0079] This application possesses any of the aforementioned magnetic adjustment buckles, thus possessing all the beneficial effects of the aforementioned magnetic adjustment buckles, which will not be elaborated further here.

[0080] Specifically, such as Figures 16 to 26 As shown, the product body 50 is a product that needs to be opened and closed, such as shoes, clothing, bags, watches, medical protective gear, hats, gloves or pet supplies. In this application, the magnetic adjustment buckle is mainly to facilitate the user's opening and closing operation of the parts of the product that need to be opened and closed.

[0081] In some embodiments, such as Figure 16 and Figure 17 As shown, when the magnetic adjustment buckle is applied to shoes in this application, it functions similarly to a shoelace, and is positioned at the shoe opening or the back opening. In this application, the female magnetic adjustment buckle 10 is fixed to the shoe opening, and the male magnetic adjustment buckle 20 is fixed to the corresponding top of the buckle. Thus, when putting on shoes, the buckle is first opened, disengaging the male buckle 20 from the female buckle 10. After the user's foot enters the shoe, the buckle is lowered, and the male buckle 20 is inserted into the corresponding female buckle 10 to secure it, thus fixing the buckle on the foot and allowing the shoes to be put on. Conversely, the shoes can be removed by simply opening the male buckle 20 and disengaging it from the female buckle 10. Simultaneously, the user can adjust the buckle's tightness by inserting the male buckle 20 into different receiving cavities 11 of the female buckle 10 through the insertion part 21, ensuring the shoes fit comfortably and securely.

[0082] In some embodiments, such as Figure 18 , Figure 19 , Figure 20 As shown, when the magnetic adjustment buckle in this application is used on clothing, it functions similarly to various buttons, and is placed where the clothing needs to be opened or closed. For example... Figure 18 The magnetic adjustment buckle 10 is fixed to one side of the opening at the waist of the skirt, and the magnetic adjustment buckle 20 is fixed to the corresponding side. When closing is required, the user inserts the male buckle 20 into the female buckle 10 to close the skirt waist. Different fastening positions can be adjusted by inserting the male buckle 20 into different receiving cavities 11 of the female buckle 10, thereby adjusting the tightness of the waist closure and ensuring comfortable wear. Similarly, as... Figure 19 , Figure 20 As shown, the magnetic adjustment buckle in this application can also be applied to the waistband of pants and the back fixing part of vests. The installation and use principle is similar to that of the waist opening of skirts, and will not be described in detail here.

[0083] In some embodiments, such as Figure 21 As shown, when the magnetic adjustment buckle is applied to a bag, it can be set at various buckle locations on the bag. In this application, the female magnetic adjustment buckle 10 is fixed to the bag body, and the male magnetic adjustment buckle 20 is fixed to the top of the corresponding buckle. The user can close the buckle by inserting the male buckle 20 into the female buckle 10. Different fastening positions can be adjusted by inserting the male buckle 20 into different receiving cavities 11 of the female buckle 10, thereby adjusting the tightness of the buckle for easy use.

[0084] In some embodiments, such as Figure 22 As shown, when the magnetic adjustment buckle is applied to a watch in this application, it serves as a connecting buckle for the watch strap. In this application, the female magnetic adjustment buckle 10 is fixed to the top of the watch strap on one side, and the male magnetic adjustment buckle 20 is fixed to the top of the watch strap on the other side. The user can close the connecting buckle by inserting the male buckle 20 into the female buckle 10. Different fastening positions can be adjusted by inserting the male buckle 20 insertion part 21 into different receiving cavities 11 of the female buckle 10, thereby adjusting the tightness of the watch strap and ensuring comfortable wearing of the watch.

[0085] In some embodiments, such as Figure 23 As shown, when the magnetic adjustment buckle is applied to medical protective gear in this application, the magnetic adjustment buckle is equivalent to the fixing buckle of the medical protective gear. In this application, the female magnetic adjustment buckle 10 is fixed on one side of the medical protective gear, and the male magnetic adjustment buckle 20 is fixed on the corresponding other side of the medical protective gear. The user can complete the closure of the fixing buckle by inserting the male buckle 20 into the female buckle 10. Different fastening positions can be adjusted by inserting the male buckle 20 insertion part 21 into different receiving cavities 11 of the female buckle 10, thereby adjusting the tightness of the medical protective gear and ensuring the comfort of wearing the medical protective gear.

[0086] In some embodiments, such as Figure 24 As shown, when the magnetic adjustment buckle is applied to a hat in this application, the magnetic adjustment buckle is equivalent to the hat's fastening buckle. In this application, the female magnetic adjustment buckle 10 is fixed on one side of the fastening buckle, and the male magnetic adjustment buckle 20 is fixed on the corresponding other side of the fastening buckle. The user can close the fastening buckle by inserting the male buckle 20 into the female buckle 10. Different fastening positions can be adjusted by inserting the male buckle 20 insertion part 21 into different receiving cavities 11 of the female buckle 10, thereby adjusting the tightness of the hat's fastening buckle and ensuring the tightness and comfort of wearing the hat.

[0087] In some embodiments, such as Figure 25 As shown, when the magnetic adjustment buckle is applied to gloves in this application, the magnetic adjustment buckle is equivalent to the glove's cuff. In this application, the female magnetic adjustment buckle 10 is fixed on one side of the cuff, and the male magnetic adjustment buckle 20 is fixed on the corresponding other side of the cuff. The user can close the cuff by inserting the male buckle 20 into the female buckle 10.
