Description

Technical Field

[0001] This application relates to the field of fastener technology, and in particular to a magnetic fastener and a household item incorporating it. Background Technology

[0002] With the development of the times, the style of rope and strap buckles is becoming increasingly common in daily life, such as in backpacks, shoes and other daily necessities. To improve the convenience of buckles, using magnets to connect the separate structures of the buckles has become a feasible solution. However, current magnetic buckles are usually produced using a magnetic injection molding process, which fixes two magnets inside two plastic parts. This process has high requirements for equipment and technology, a long molding cycle, low production capacity, and a high defect rate. The high temperature during the molding process can also weaken the magnetic force of the magnets, which may require secondary magnetization to achieve the required strength, resulting in high manufacturing costs. Furthermore, the product is prone to warping and deformation after molding, affecting the fit, and its structural design dictates that the rotation angle of the product cannot exceed a certain angle.

[0003] Therefore, how to reduce the production cost of magnetic fasteners and improve their performance has become a research and development direction for those skilled in the art. Utility Model Content

[0004] The technical objective of this application is to provide a magnetic fastener that solves the problems of high cost and easy deformation of current magnetic fasteners, which affect their performance.

[0005] To address the aforementioned technical problems, this application provides a magnetic fastener, comprising:

[0006] The first fastener includes a first magnet and a first body made of a non-magnetic material. The first body includes a first attractive part and a first connecting part formed in a hook-shaped structure. The first magnet is riveted to the first attractive part.

[0007] The second fastener includes a second magnet and a second body made of non-magnetic material. The second body includes a second attraction part and a first rope connection part with a hole. The second magnet is riveted to the second attraction part. The second attraction part is correspondingly arranged with the first attraction part, and the end of the second attraction part away from the first rope connection part is spaced at a preset distance from the first connection part.

[0008] The connecting buckle includes a second connecting part and a second rope connecting part with a hole, the second connecting part being connected to the first connecting part, and the width and / or thickness of the second connecting part being greater than the preset distance.

[0009] Specifically, in the magnetic fastener described above, at least one magnet mounting groove is provided on the first and second engaging parts respectively, and at least one hollow groove is provided around the magnet mounting groove.

[0010] Preferably, in the magnetic fastener described above, each of the magnetic mounting slots has at least two sections of retaining wall adhesive joints, and the first magnet and the second magnet are bonded to the retaining wall adhesive joints in the corresponding magnetic mounting slots.

[0011] Specifically, in the magnetic fastener described above, the first engaging part has two magnet mounting slots, and a guide post is provided between the two magnet mounting slots;

[0012] The second suction part has two magnet mounting slots, and a guide slot corresponding to the guide post is provided between the two magnet mounting slots.

[0013] Specifically, in the magnetic fastener described above, the number of the hollowed-out slots is at least two.

[0014] Optionally, in the magnetic fastener described above, the at least two of the hollowed-out slots are of the same size.

[0015] Optionally, in the magnetic fastener described above, the at least two of the hollowed-out slots are of different sizes.

[0019] Compared with the prior art, the magnetic fastener provided in this application has at least the following beneficial effects:

[0020] The magnetic fastener of this application uses a riveting process to install the magnet, rather than the traditional injection molding process. This avoids the weakening of the magnet's magnetism due to high temperatures, thus further eliminating the need for secondary magnetization and reducing production costs. It also eliminates the need for secondary processing of the molded magnetic fastener, such as hollowing or drilling, thereby preventing warping and deformation due to stress and ensuring a secure fit. Furthermore, the hook-shaped structure connecting the corresponding fastener body increases the rotation range of the fastener body while maintaining connection stability, making it easier for the magnetic fastener to adhere to other object surfaces.

In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0036] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0037] In the various embodiments of this application, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0038] It should be understood that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0039] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean that B is determined solely based on A, but can also be determined based on A and / or other information.

[0040] See Figures 1 to 12One embodiment of this application provides a magnetic fastener, comprising:

[0041] The first fastener 1 includes a first magnet and a first body made of non-magnetic material. The first body includes a first suction part 101 and a first connecting part 102 formed in a hook-shaped structure. The first magnet is riveted to the first suction part 101.

[0042] The second fastener 2 includes a second magnet and a second body made of non-magnetic material. The second body includes a second attraction part 201 and a first rope connection part 202 with a hole. The second magnet is riveted to the second attraction part 201. The second attraction part 201 is correspondingly disposed with the first attraction part 101, and the end of the second attraction part 201 away from the first rope connection part 202 is spaced at a preset distance from the first connection part 102.

[0043] The connecting buckle body 3 includes a second connecting part 301 and a second rope connecting part 302 with a hole. The second connecting part 301 is connected to the first connecting part 102, and the width and / or thickness of the second connecting part 301 is greater than the preset distance.

[0044] The magnetic buckle provided in this embodiment connects the first buckle body 1 and the second buckle body 2 by riveting a first magnet and a second magnet to the first attraction part 101 and the second attraction part 201 of the non-magnetic first body, respectively. The magnetic attraction between the first magnet and the second magnet causes the first attraction part 101 and the second attraction part 201 to fit tightly together, thus connecting the first buckle body 1 and the second buckle body 2. The second connecting part 301 on the connecting buckle body 3 first connects to the hook-shaped first connecting part 102. For example, the hook-shaped first connecting part 102 passes through the second connecting part 301, thus connecting the first connecting part 102 and the second connecting part 301. Furthermore, after the first buckle body 1 and the second buckle body 2 are connected, the engagement between the second attraction part 201 and the first connecting part 102 seals the hook-shaped first connecting part 102, preventing the first connecting part 102 from separating from the second connecting part 301 and ensuring a stable connection. At this point, the magnetic buckle can be practically applied simply by threading a rope or webbing through the corresponding first rope connecting part 202 and second rope connecting part 302. Furthermore, the magnetic connection between the first buckle body 1 and the second buckle body 2 facilitates locking and unlocking of the buckle, ensuring the stability of the connection when locked.

[0045] In summary, the magnetic buckle of this application uses a riveting process to install the magnet, rather than the traditional injection molding process, avoiding magnet weakening due to high temperatures and thus eliminating the need for secondary magnetization, which helps reduce production costs. It eliminates the need for secondary processing of the molded magnetic buckle, such as hollowing or drilling, thus preventing warping and deformation due to stress and ensuring a good fit. The hook-shaped structure connecting the corresponding buckle body 3 increases the rotation range of the buckle body 3 while ensuring connection stability, making it easier for the magnetic buckle to adhere to other surfaces, such as shoes, allowing for a better fit. Furthermore, since the buckle body 3 is less likely to contact the second buckle body 2 when rotating based on the second connecting part 301, the dimensions of the first buckle body 1, the second buckle body 2, and / or the connecting buckle body 3 can be relatively reduced, thus saving production costs.

[0046] See Figure 3 , Figure 5 , Figure 6 , Figure 9 and Figure 11 Specifically, in the magnetic fastener described above, at least one magnet mounting groove 4 is provided on the first suction part 101 and the second suction part 201 respectively, and at least one hollow groove 5 is provided around the magnet mounting groove 4.

[0047] In this embodiment, a structure for mounting magnets on the first snap-fit ​​body 1 and the second snap-fit ​​body 2 is illustrated. At least one magnet mounting groove 4 is provided on each of the first and second suction parts 101 and 201, respectively, for mounting magnets. This corresponding arrangement ensures the accuracy of the connection between the first and second snap-fit ​​bodies 1 and 2, and the stability of the connection after connection. Furthermore, at least one hollow groove 5 is provided around the magnet mounting groove. The hollow groove 5 avoids the impact of drilling or removing material from the first and second snap-fit ​​bodies 1 and 2 after molding on the overall stress. Simultaneously, when riveting the magnet, the groove wall around the magnet mounting groove 4 is subjected to pressure. The hollow groove 5 allows the magnet mounting groove 4 to elastically deform, minimizing this pressure and allowing the magnet mounting groove 4 to return to its original three-dimensional state as much as possible. This facilitates the riveting of the magnet into the corresponding magnet mounting groove 4.

[0048] See Figure 9 Preferably, in the magnetic fastener described above, each of the magnetic mounting slots 4 is provided with at least two sections of retaining wall adhesive joints 401, and the first magnet and the second magnet are bonded to the retaining wall adhesive joints 401 in the corresponding magnetic mounting slots 4.

[0049] In this embodiment, at least two retaining wall adhesive joints 401 are also provided in the magnet mounting groove 4, and the magnet is glued to the retaining wall adhesive joints 401 to further ensure the stability of the magnet installation. When the magnet is riveted, the adhesive at the retaining wall adhesive joint 401 will deform under the squeezing force of the magnet, and will try to return to its newly formed three-dimensional state after installation, thereby increasing the friction force on the magnet and further improving the stability of the magnet installation.

[0050] See Figure 3 , Figure 5 , Figure 6 , Figure 9 and Figure 11 Specifically, in the magnetic fastener described above, there are two magnet mounting slots 4 on the first engaging part 101, and a guide post 1011 is provided between the two magnet mounting slots 4.

[0051] The second suction part 201 has two magnet mounting slots 4, and a guide slot 2011 corresponding to the guide post 1011 is provided between the two magnet mounting slots 4.

[0052] In this embodiment, both the first suction part 101 and the second suction part 201 are provided with two magnet mounting slots 4, so that the first buckle body 1 and the second buckle body 2 have two connection points, which helps to limit the degree of freedom of the first buckle body 1 and the second buckle body 2 after connection and ensures the stability of the connection. Furthermore, the first suction part 101 is provided with a guide post 1011, and the second suction part 201 is provided with a corresponding guide groove 2011, which can further improve the stability of the connection and facilitate the connection of the first buckle body 1 and the second buckle body 2.

[0053] See Figure 3 , Figure 5 , Figure 6 , Figure 9 and Figure 11 Specifically, in the magnetic fastener described above, the number of the hollowed-out slots 5 is at least two.

[0054] In one specific embodiment, there are at least two hollowed-out grooves 5 around each magnet mounting groove 4, so that there are at least two connection points between the magnet mounting groove 4 and the corresponding suction part. This not only ensures convenient and stable installation of the magnet, but also helps to ensure the positional relativity between the magnet mounting groove 4 and the corresponding suction part.

[0055] See Figure 3 , Figure 5 , Figure 9 and Figure 11 Optionally, in the magnetic fastener described above, the at least two of the hollowed-out slots 5 are of the same size.

[0056] In one specific embodiment, by setting the size of the hollowed-out grooves 5 around the same magnet mounting groove 4 to be the same, it is beneficial to evenly distribute stress or force and ensure structural stability.

[0057] See Figure 6 Optionally, in the magnetic fastener described above, the at least two of the hollowed-out slots 5 are of different sizes.

[0058] In another specific embodiment, by setting the size of the hollowed-out grooves 5 around the same magnet mounting groove 4 to be different, the position and size of the hollowed-out grooves 5 can be adjusted according to actual needs, so that they are more in line with the force environment of the magnet fastener.

[0059] See Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 Preferably, in the magnetic buckle as described above, a first weight-reducing hole 103 is provided at the end of the first body away from the first connecting part 102, and the first weight-reducing hole 103 is formed as an elongated hole.

[0060] In this embodiment, a first weight-reducing hole 103 is provided at the end of the first body away from the first connecting part 102. The first weight-reducing hole 103 can further reduce the weight of the magnetic buckle and save material costs. At the same time, the first weight-reducing hole 103 is formed into an elongated hole, which can be used as a connecting hole for rope to pass through to connect the rope, thereby ensuring the stability of the connection between the magnetic buckle and the rope when in use.

[0061] See Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 Preferably, in the magnetic fastener described above, the first body is provided with a second weight-reducing hole 104 corresponding to the guide post 1011, and the second weight-reducing hole 104 penetrates the part of the guide post 1011 near the first body.

[0062] In this embodiment, the first body also has a second weight-reducing hole 104 corresponding to the guide post 1011 to further reduce the weight of the first body. The second weight-reducing hole 104 penetrates the part of the guide post 1011 near the first body, so that the guide post 1011 is formed into an inverted L-shaped structure, so as to be snapped into the guide groove 2011 penetrating the second body. This helps to improve the tensile force that the magnetic buckle can withstand, so as to meet the user's usage needs.

[0063] See Figure 12Another embodiment of this application provides a household item, including: a rope 6 and a magnetic buckle as described above, wherein two ropes 6 are respectively threaded through the first rope connecting portion and the second rope connecting portion and connected to the magnetic buckle. This household item can achieve the technical effects described above through the magnetic buckle; therefore, the technical features and beneficial effects of this embodiment will not be elaborated further here.

[0064] Furthermore, reference numerals and / or letters may be repeated in different examples within this application. Such repetition is for the purpose of simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed.

[0066] The above description is the preferred embodiment of this application.
