[0035] The core of this utility model is to provide a magnetic snap fastener with a tongue that is an elastic element, and the through hole of the tongue is smaller than the cross-sectional size of the assembly after the protrusion and the first hook are engaged, so as to ensure the stability of the structure after the pressure strip and the upper snap fastener are engaged.

[0036] Another key aspect of this invention is to provide a bag or luggage that includes the aforementioned magnetic clasp.

[0037] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] The magnetic snap fastener provided in this application includes: a tongue 1, a pressure plate 3, an upper snap fastener 6, a first magnetic element 9, a lower snap fastener 10, and a second magnetic element 12;

[0039] Among them, the surface of the tongue 1 is provided with a through hole 2;

[0040] The surface of the pressure sheet 3 is provided with a protrusion 4, which is disposed through the through hole 2, and the protrusion 4 is provided with a hook groove 5;

[0041] The first end face of the upper fastener 6 is provided with a first hook 7 that matches the hook groove 5, and the second end face is provided with a second hook 8. The size of the through hole 2 is smaller than the cross-sectional size of the assembly after the protrusion 4 and the first hook 7 are engaged.

[0042] The first magnetic element 9 is disposed between the pressure strip 3 and the upper fastening strip 6;

[0043] The surface of the lower fastener 10 is provided with a hook groove 11 that matches the second hook 8;

[0044] The second magnetic element 12 is disposed on the lower fastener 10, and the first magnetic element 9 has the opposite magnetic properties to the second magnetic element 12.

[0045] Specifically, the structure of the protrusion 4 and the hook groove 5 on the surface of the pressure plate 3 can be found in the attached document. Figure 2 With appendix Figure 5 The structure of the upper fastener 6 and the first hook 7 can be referred to in the appendix. Figure 1 With appendix Figure 6The tongue 1 is a strip-shaped structure with a certain thickness. The tongue 1 is provided with a through hole 2 through which it passes. The pressure plate 3 is provided with a protrusion 4 on the surface of one end facing the tongue 1. The side of the protrusion 4 is provided with a hook groove 5. The upper fastener 6 is provided with a first hook 7 on the surface of one end facing the tongue 1. The protrusion 4 and the first hook 7 can be inserted into the through hole 2 from both ends of the tongue 1 respectively, and the first hook 7 can engage with the hook groove 5 in the through hole 2. When the first hook 7 engages with the hook groove 5, the pressure plate 3 and the upper fastener 6 can fit against the tongue 1. In addition, the through hole 2 on the surface of the tongue 1 should be slightly smaller than the cross-sectional size of the assembly after the protrusion 4 and the first hook 7 are engaged. Through the elasticity of the tongue 1 itself, it can exert a squeezing effect on the first hook 7 and the protrusion 4, thereby ensuring that the pressure plate 3 and the upper fastener 6 can be stably installed on the tongue 1, ensuring the stability of the structure.

[0046] Based on this, a first magnetic element 9 is provided between the upper buckle 6 and the tongue 1, and a second hook 8 is provided on the surface of the upper buckle 6 away from the first hook 7. A second magnetic element 12 and a hook groove 11 are provided on the lower buckle 10. It should be noted that the first magnetic element 9 and the second magnetic element 12 have opposite magnetic properties. According to the principle of opposite poles attracting, when the first magnetic element 9 and the second magnetic element 12 are close, the magnetic force between them can make the upper buckle 6 and the lower buckle 10 close together. With the second hook 8 and the hook groove 11, the two can be engaged.

[0047] Optionally, a belt can be used for the tongue, which is a relatively common material and has a relatively low cost.

[0048] Based on the above embodiment, the hook groove 5 is provided on the side of the protrusion 4 near the pressure strip 3, the end of the protrusion 4 away from the pressure strip 3 is provided with an arc-shaped surface, and the end of the first hook 7 away from the upper buckle 6 is provided with an inclined surface.

[0049] Specifically, the structure of the hook groove 5 can be found in the attached document. Figure 2 With appendix Figure 5 The protrusion 4 has an arc-shaped surface at the end opposite to the pressure strip 3, and the first hook 7 also has an inclined surface at the end opposite to the upper buckle 6. During the process of the first hook 7 engaging with the hook groove 5, the arc-shaped surface and the inclined surface come into contact, which makes it easier to engage the first hook 7 with the protrusion 4 and reduces the installation difficulty of the pressure strip 3 and the upper buckle 6.

[0050] Optionally, both the pressure strip 3 and the upper buckle 6 can be made of plastic. Therefore, the first hook 7 and the protrusion 4 have a certain elasticity. During the process of the protrusion 4 and the first hook 7 being engaged in the through hole 2, a certain elastic deformation needs to be generated. Using plastic to make the pressure strip 3 and the upper buckle 6 can meet the aforementioned requirements.

[0051] Based on the above embodiment, four through holes 2 are provided and distributed along the four corners of the rectangle, and four protrusions 4, four hook grooves 5 and four first hooks 7 are provided.

[0052] Specifically, the structure of tongue 1 can be found in the appendix. Figure 1 With appendix Figure 2 The surface of the device has four through holes 2. In this application, the through holes 2 are square or rectangular holes. The size of the through holes 2 is determined according to the cross-sectional size of the assembly after the protrusion 4 and the first hook 7 are engaged. That is, as mentioned above, the size of the through holes 2 should be slightly smaller than the cross-sectional size of the assembly after the protrusion 4 and the first hook 7 are engaged. There are four through holes 2, protrusion 4, hook groove 5 and first hook 7. Compared with only one through hole 2, the connection between the pressure strip 3, the upper buckle 6 and the tongue 1 can be stabilized to a greater extent, thus improving the stability of the magnetic buckle.

[0053] Based on the above embodiment, the hook groove 5 and the first hook 7 are both divided into two groups, the opening directions of the two groups of hook groove 5 are arranged opposite to each other, and the hook heads of the two groups of first hook 7 are arranged facing each other.

[0054] Specifically, with attachment Figure 1 With appendix Figure 2 Taking the direction and structure as an example, there are four protrusions 4 and four first hooks 7. The two protrusions 4 located on the upper side of the pressure plate 3 are group A, the two protrusions 4 located on the lower side of the pressure plate 3 are group B, the two first hooks 7 located on the upper side of the upper buckle 6 are group C, and the two first hooks 7 located on the lower side of the upper buckle 6 are group D. The hook groove 5 of the protrusions 4 in group A opens upward, the hook groove 5 of the protrusions 4 in group B opens downward, and the hook head of the first hook 7 in group C extends downward. When installing the pressure plate 3 and the upper buckle 6, the protrusions 4 in group A and the first hooks 7 in group C are engaged accordingly, and the protrusions 4 in group B and the first hooks 7 in group D are engaged accordingly, so that the protrusions 4 and the first hooks 7 can be engaged in a clamping manner.

[0055] Optionally, the opening direction of the hook groove 5 on the protrusion 4 can be set to face away from each other. It is not limited to the above-mentioned upward or downward opening. It can also open to the left or right. Correspondingly, the hook head of the first hook 7 is set to face towards each other. In order to match the hook groove 5, the hook head of the first hook 7 is also modified to extend to the right or left.

[0056] Based on the above embodiment, both sides of the pressure strip 3 are provided with protective edges 13 for covering the tongue 1.

[0057] For details, please refer to the appendix. Figure 1 Appendix Figure 2 With appendix Figure 3A guard edge 13 is provided on both sides of the pressure plate 3. The guard edge 13 is perpendicular to the pressure plate 3 and extends towards the tongue 1. When the pressure plate 3 is installed on the pressure plate 3, the guard edge 13 can cover the side of the tongue 1. The setting of the guard edge 13 can position the tongue 1, making the entire magnetic buckle more stable after the pressure plate 3 is installed.

[0058] Based on the above embodiment, ribs 14 are provided on both sides of the hook groove 5.

[0059] For details, please refer to the appendix. Figure 5 The protrusion 4 extends from the upper left to the lower right. The hook groove 5 on the protrusion 4 is a rectangular cavity that is snapped out from the protrusion 4. The hook groove 5 can form ribs 14 on both sides of the hook groove 5. The ribs 14 can improve the structural strength of the protrusion 4 and can limit the first hook 7, making the connection between the pressure strip 3 and the upper buckle 6 more stable.

[0060] Based on the above embodiment, the upper fastener 6 has a first groove 15 for mounting the first magnetic element 9 on the side surface facing the tongue 1, and the lower fastener 10 has a second groove 16 for mounting the second magnetic element 12 on the side surface facing away from the upper fastener 6.

[0061] Specifically, the structure of the upper clip 6 can be found in the attached document. Figure 6 A first recessed groove 15 is provided at the middle position of the upper fastener 6. The structure of the lower fastener 10 can be referred to in the appendix. Figure 2 The lower fastener 10 has a second groove 16 on the side surface opposite to the upper fastener 6. The structure of the first groove 15 matches the structure of the first magnetic element 9, and the structure of the second groove 16 matches the structure of the second magnetic element 12. Taking this application as an example, both the first magnetic element 9 and the second magnetic element 12 are cylindrical magnets. Correspondingly, both the first groove 15 and the second groove 16 are cylindrical grooves, which facilitates assembly.

[0062] Based on the above embodiments, both the first groove 15 and the second groove 16 are provided with a plurality of through holes 17.

[0063] For details, please refer to the appendix. Figure 1 With appendix Figure 2 The first groove 15 is provided with a through hole 17 for passing through the pressure strip 3, and the second groove 16 is provided with a through hole 17 for passing through the lower fastener 10. The number of through holes 17 is set to be several, and the through holes 17 on the upper fastener 6 and the lower fastener 10 should be correspondingly set to ensure the magnetism of the magnets set in the first groove 15 and the second groove 16, and to ensure the magnetic attraction effect of the upper fastener 6 and the lower fastener 10.

[0064] Based on the above embodiments, the tongue 1 is a leather belt or a cloth belt.

[0065] Specifically, the tongue 1 is made of a leather belt or cloth belt to have a certain degree of elasticity. As previously explained, when the hook groove 5 and the first hook 7 are engaged in the through hole 2, the size of the combination of the first hook 7 and the hook groove 5 is slightly smaller than the size of the through hole 2. The tongue 1 is made of an elastic material so that the combination of the first hook 7 and the hook groove 5 can be subjected to elastic force by the side wall of the through hole 2 to ensure structural stability.

[0066] Based on the above embodiment, the included angle between the second hook 8 and the upper fastener 6 is an acute angle.

[0067] For details, please refer to the appendix. Figure 1 With appendix Figure 4 There are two second hooks 8, and the two second hooks 8 are respectively located near the end of the upper buckle 6. The included angle between the second hook 8 and the upper buckle 6 is an acute angle. The lower buckle 10 is provided with a hook groove 11 that is also inclined, so as to realize the snap-fit ​​positioning of the upper buckle 6 and the lower buckle 10.

[0068] In addition to the magnetic snap fasteners mentioned above, this utility model also provides a bag that includes the magnetic snap fasteners disclosed in the above embodiments. For the structure of other parts of the bag, please refer to the prior art, which will not be repeated here.
