[0047] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0048] Please see Figures 1 to 4 The magnetic fastener 100 of the first embodiment includes a male fastener 1, a female fastener 2, a release operation member 3, and a first magnetic attraction structure 4 and a second magnetic attraction structure 5 that are magnetically attracted to each other. The male fastener 1 has a locking part 1a, and the female fastener 2 has a mating locking part 2a for engaging with the locking part 1a. The first magnetic attraction structure 4 is provided on the male fastener 1, and the second magnetic attraction structure 5 is provided on the female fastener 2. The male fastener 1 and the female fastener 2 are mated together in a direction close to each other, thereby locking the locking part 1a and the mating locking part 2a. The first magnetic attraction structure 4 and the second magnetic attraction structure 5 are magnetically attracted to each other during the mating process, thereby making the fastening of the male fastener 1 and the female fastener 2 faster. The release operation member 3 is movably provided on the male fastener 1. When the release operation member 3 selectively releases the locking part 1a and the mating locking part 2a to allow the male fastener 1 and the female fastener 2 to be pulled out from each other, the first magnetic attraction structure 4 and the second magnetic attraction structure 5 are magnetically attracted to each other, keeping the male fastener 1 and the female fastener 2 in a mated state. Of course, in other embodiments, the first magnetic attraction structure 4 provided on the male buckle 1 and the second magnetic attraction structure 5 provided on the female buckle 2 can also magnetically repel each other. By means of the mutual magnetic repulsion between the first magnetic attraction structure 4 and the second magnetic attraction structure 5, the locking part 1a and the mating locking part 2a after fastening remain in a mutually abutting state, thus making the fastening more reliable. Therefore, this is not limited to the examples described above. Specifically, in this embodiment, the magnetic buckle 100 of this embodiment also includes an outer cover 6, the male buckle 1 is built into the outer cover 6, and the release operation member 3 is along the mating direction (e.g., ...). Figure 4The upper and lower directions) is movably disposed on the outer cover 6, preferably, the release operation member 3 is a circular button, so that the user can release the locking portion 1a and the counter locking portion 2a by pressing the release operation member 3; the outer cover 6 is provided with a through hole 61 for the release operation member 3 at one end (such as Figure 4 the upper end of the outer cover 6) in the counter direction, and is provided with a counter hole 62 for the counter locking portion 2a at the other end (such as Figure 4 the lower end of the outer cover 6) in the counter direction, so that the male buckle 1 and the female buckle 2 can be more stable during operation, and dust can be blocked to reduce the wear of the male buckle 1 and the female buckle 2 caused by the outside world, thereby prolonging the service life of the magnetic buckle 100 and being more beautiful and elegant. It can be understood that in other embodiments, the counter locking portion 2a can be formed on the male buckle 1, and the locking portion 1a can be formed on the female buckle 2; when the locking portion 1a is formed on the female buckle 2, the release operation member 3 is correspondingly provided on the female buckle 2, and the outer cover 6 can be deleted according to actual needs, so the above examples are not limited. More specifically, as follows:

[0049] In combination with Figure 5 and Figure 6 , the locking portion 1a is a resilient structure, and the counter locking portion 2a has a pushing structure 21 and a locking structure 22; during the counter process, the pushing structure 21 pushes the locking portion 1a to make the locking portion 1a elastically deform, so that the locking portion 1a slides to a position where the locking portion 1a is locked with the locking structure 22, as shown in Figure 4 ; the release operation member 3 selectively drives the locking portion 1a to elastically deform and separate from the locking of the locking structure 22. Therefore, the locking structure 22 is made to be locked with the locking portion 1a more quickly and smoothly by the pushing structure 21. Specifically, in this embodiment, the locking portion 1a includes a resilient arm 11 and a lock head 12 for locking with the locking structure 22, the lock head 12 is connected with the resilient arm 11, and preferably, the resilient arm 11 and the lock head 12 form an integral structure, so that the lock head 12 is suspended at the middle of the male buckle 1 by the resilient arm 11, as shown in Figure 3The elastic arms 11 have the tendency to drive the lock heads 12 to lock with the lock structure 22; therefore, during the mating process, the pushing structure 21 pushes the lock heads 12 to drive the elastic arms 11 to be elastically deformed, so that the lock heads 12 slide to the position of locking with the lock structure 22, thereby realizing the automatic locking of the male buckle 1 and the female buckle 2 during the mating process; the unlocking operation member 3 selectively drives the elastic arms 11 to be elastically deformed, so that the lock heads 12 are separated from the lock structure 22; preferably, the unlocking operation member 3 pushes the elastic arms 11 along the direction parallel to the mating direction, so that the elastic arms 11 are elastically deformed along the direction intersecting the mating direction, thereby separating the lock heads 12 from the lock structure 22, so that the unlocking process between the lock heads 12 and the lock structure 22 is simple. For example, in the embodiment, the elastic arms 11 are two and arranged around the mating lock structure 2a; each elastic arm 11 is connected with the lock head 12, so that the lock heads 12 are arranged around the lock structure 22, thereby making the lock heads 12 more reliably lock with the lock structure 22, so that the locking of the male buckle 1 and the female buckle 2 is more stable and reliable; of course, in other embodiments, the number of the elastic arms 11 can be three, four or five, and is not limited to this; preferably, the lock head 12 is selected as a hook structure, and the lock structure 22 is a hook groove, so that the magnetic buckle 100 of the embodiment is more tightly locked and is not easy to be separated; at the same time, the male buckle 1 is a hollow structure, and the middle part of the male buckle 1 has a transversely arranged middle supporting arm 14, which is located between the two elastic arms 11 and connected to the corresponding two side walls of the male buckle 1, so as to increase the strength of the male buckle 1.

[0050] Please refer to Figures 3 to 6 , the end of the pushing structure 21 has a first inclined structure 211 inclined relative to the mating direction (such as the up-down direction shown in Figure 4 ); the lock head 12 has a second inclined structure 121 matched with the first inclined structure 211; during the mating process, the first inclined structure 211 pushes the second inclined structure 121, so that the pushing structure 21 easily passes the lock head 12, and the pushing structure 21 slides to the position of locking the lock structure 22 with the lock head 12, thereby facilitating the locking of the male buckle 1 and the female buckle 2.

[0051] Please refer to Figures 3 to 6The releasing operation member 3 has a pushing inclined surface 31 inclined relative to the direction of plugging, and the releasing operation member 3 pushes the elastic arm 11 by the pushing inclined surface 31 to produce elastic deformation, so that the lock head 12 is released from the matched locking structure 22. Since the lock head 12 is arranged to embrace the matched locking structure 22, the pushing inclined surface 31 is inclined from inside to outside in the direction away from the pushing structure 21, and the releasing operation member 3 pushes the elastic arm 11 by the pushing inclined surface 31 to produce elastic deformation, so that the elastic arm 11 drives the lock head 12 to be released from the matched locking structure 22. Of course, in other embodiments, the elastic arm 11 can drive the lock head 12 to be released from the matched locking structure 22, and thus is not limited to this. For example, in this embodiment, the releasing operation member 3 extends outwardly along the direction parallel to the direction of plugging to form a spreading leg 32, and the pushing inclined surface 31 is formed on the spreading leg 32. The end of the elastic arm 11 connected with the lock head 12 has a pushing-receiving inclined surface 111 matched with the pushing inclined surface 31, and the releasing operation member 3 pushes the elastic arm 11 by the pushing inclined surface 31 matched with the pushing-receiving inclined surface 111 to produce elastic deformation, so that the lock head 12 is released from the matched locking structure 22. Preferably, the end of the elastic arm 11 connected with the lock head 12 is provided with a groove 112, the spreading leg 32 is arranged in the groove 112, the pushing-receiving inclined surface 111 is formed on the groove wall surface of the groove 112, and the pushing inclined surface 31 is formed on the end surface of the spreading leg 32, so that the structure of the releasing operation member 3 pushing the elastic arm 11 to produce elastic deformation is simpler, and the spreading leg 32 directly acts on the groove 112 of the end connected with the lock head 12, so that the elastic arm 11 is rapidly deformed, the lock head 12 is rapidly released from the matched locking structure 22, and thus is not limited to this.

[0052] Please refer to Figure 3 , Figure 4 and Figure 6The male buckle 1 is provided with a first embedding cavity 13, the female buckle 2 is provided with a second embedding cavity 23, the first magnetic attraction structure 4 is embedded in the first embedding cavity 13, and the second magnetic attraction structure 5 is embedded in the second embedding cavity 23, so that the first magnetic attraction structure 4 is hidden in the male buckle 1, and the second magnetic attraction structure 5 is hidden in the female buckle 2. Specifically, the first embedding cavity 13 is aligned with the second embedding cavity 23 along the plug-in direction, so that the magnetic force between the first magnetic attraction structure 4 and the second magnetic attraction structure 5 is maximized, thereby making the plug-in between the male buckle 1 and the female buckle 2 faster, while keeping a maximum magnetic attraction force between the male buckle 1 and the female buckle 2 after plugging, effectively preventing the male buckle 1 and the female buckle 2 from accidentally separating. For example, the second embedding cavity 23 is formed in the plug-in lock part 2a, and the first embedding cavity 13 is formed at the middle part of the male buckle 1, specifically at the middle part of the middle support arm 14, so that the magnetic buckle 100 of the application has reasonable space utilization and saves materials; at the same time, the first magnetic attraction structure 4 and the second magnetic attraction structure 5 are each a magnet; of course, in other embodiments, one of the first magnetic attraction structure 4 and the second magnetic attraction structure 5 is a magnet, and the other is a metal structure, so it is not limited to this; preferably, the thickness of the first magnetic attraction structure 4 ranges from 3.0 to 5.5 millimeters, preferably 3.0, 3.8, 4.5, 5.0 or 5.5 millimeters. It is worth noting that when the plug-in lock part 2a is formed on the male buckle 1, the first embedding cavity 13 is formed in the plug-in lock part 2a at this time.

[0053] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the female buckle 2 and the outer cover 6 each have an assembly end for assembling the woven belt. Preferably, the assembly end on the female buckle 2 is two and arranged opposite, and the assembly end on the outer cover 6 is one and always arranged back to the assembly end on the female buckle 2, so as to facilitate the assembly of the woven belt. For example, the assembly end of the female buckle 2 and the outer cover 6 is provided with a through hole 24, 63 for the woven belt to pass through, the female buckle 2 can be fixed on the first cloth surface (not shown in the figure) by the two assembly ends and the woven belt passing through the two assembly ends, and the male buckle 1 can be fixed by the assembly end of the outer cover 6 and the woven belt connected to the second cloth surface (not shown in the figure), thereby realizing the detachable combination between the first cloth surface and the second cloth surface. In other embodiments, the plug-in lock part 2a is a cylindrical structure, so that the male buckle 1 and the female buckle 2 can be selectively rotated around the plug-in lock part 2a, thereby making the work of the male buckle 1 and the female buckle 2 more flexible, and at the same time, any assembly end on the female buckle 2 can be used together with the assembly end on the outer cover 6 after rotation. When one of the assembly ends on the female buckle 2 is damaged, by rotating the female buckle 2, the other assembly end is used together with the assembly end on the outer cover 6, so that the magnetic buckle 100 of the application is durable.

[0054] Please refer to Figures 7 to 10The second embodiment is shown. The magnetic buckle 100a of the second embodiment is basically the same as the first embodiment, and the differences are as follows:

[0055] First, the outer cover 6 of the second embodiment has ribs 64 protruding therefrom. The ribs 64 are located at the side walls of the outer cover 6. Preferably, the ribs 64 are located at the opposite side walls of the outer cover 6. The ribs 64 increase the frictional resistance, which facilitates the operation of the magnetic buckle 100a by the operator. In the first embodiment, the outer cover 6 does not have ribs 64 protruding therefrom.

[0056] Second, the second embodiment has a push slope 31 of the spreading leg 32 that is in push fit with the end of the elastic arm 11 away from the lock head 12. The push slope 31 of the spreading leg 32 directly applies force to the end of the elastic arm 11 away from the lock head 12. That is, the spreading leg 32 is located between the elastic arm 11 and the intermediate support arm 14. Therefore, the second embodiment does not have a push slope 111 and a groove 112 on the elastic arm 11 that cooperate with the push slope 31. Since the spreading legs 32 of the second embodiment are arranged in pairs and are spaced apart, the intermediate support arm 14 is clamped in the gap between the spreading legs 32 arranged in pairs.

[0057] Third, since the push slope 31 of the spreading leg 32 of the second embodiment directly applies force to the end of the elastic arm 11 away from the lock head 12, in order to make the release operation member 3 more reliable in resetting, the magnetic buckle 100a of the second embodiment further includes a resilient member 7 that provides elastic force for resetting the release operation member 3. The resilient member 7 is preferably a spring, but can also be designed as a resilient plastic structure according to actual needs. The resilient member 7 abuts between the release operation member 3 and the male buckle 1, but is not limited thereto. In the first embodiment, since the push slope 31 of the spreading leg 32 applies force to the end of the elastic arm 11 connected to the lock head 12, the resetting of the release operation member 3 is achieved by the elastic arm 11.

[0058] Fourth, in the second embodiment, the thickness of the first magnetic attraction structure 4 is 5.0 mm. In the first embodiment, the thickness of the first magnetic attraction structure 4 is 3.8 mm.

[0059] In addition to the above differences, the second embodiment is the same as the first embodiment, and therefore will not be described again here.

[0060] Please refer to Figures 11 to 13 The third embodiment is shown. The magnetic buckle 100b of the third embodiment is basically the same as the magnetic buckle 100a of the second embodiment, and the differences are as follows:

[0061] First, in the third embodiment, the release operation member 3 is a square button. In the second embodiment, the release operation member 3 is a circular button.

[0062] Second, in the third embodiment, the outer cover 6 does not have ribs 64 protruding therefrom. In the second embodiment, the outer cover 6 has ribs 64 protruding therefrom.

[0063] Third, in the present embodiment, the elastic member 7 is in contact with the release operating member 3 and the male buckle 1, and is offset from the first embedding cavity 13; while in the second embodiment, the elastic member 7 is in contact with the release operating member 3 and the male buckle, and is directly opposite the first embedding cavity 13.

[0064] In addition to the above differences, other aspects are the same as the second embodiment, and thus will not be described here.

[0065] In combination Figures 1 to 6 The working principle of the magnetic buckle 100 of the first embodiment of the present application is described as follows: when the magnetic buckle 100 of the present embodiment is switched from the locked state to the released state, the release operating member 3 is pressed downward, the spreading leg 32 below the release operating member 3 is in contact with the groove 112 of the elastic arm 11 and pushes the groove 112, so that the pushing slope 31 on the spreading leg 32 cooperates with the pushed slope 111 on the groove 112, thereby causing the elastic arm 11 to spread outward, driving the lock head 12 connected with the elastic arm 11 to spread outward, thereby disengaging from the locking structure 22 on the counter-locked locking portion 2a, so that the male buckle 1 and the female buckle 2 are in the released state; at the same time, the female buckle 2 and the male buckle 1 are pulled apart in the opposite direction of the counter-locked, so that the pulling force is greater than the mutual magnetic attraction force between the first magnetic attraction structure 4 and the second magnetic attraction structure 5, thereby realizing the mutual disengagement of the male buckle 1 and the female buckle 2. When the male buckle 1 and the female buckle 2 are to be buckled, the counter-locked locking portion 2a is first aligned with the counter-locked hole 62 in the outer cover 6; then the male buckle 1 and the female buckle 2 are brought close to each other, and under the mutual magnetic attraction of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, the pushing structure 21 on the counter-locked locking portion 2a easily passes over the lock head 12, thereby causing the locking structure 22 and the lock head 12 to be locked with each other, realizing the locking of the male buckle 1 and the female buckle 2, as shown in Figure 4

[0066] In combination Figures 7 to 10 ​When the magnetic fastener 100a of the second embodiment is switched from the locked state to the unlocked state, the elastic member 7 is in the compressed state by pressing the unlocking operation member 3 downward, the pushing inclined surface 31 of the opening leg 32 below the unlocking operation member 3 directly applies force to the end of the elastic arm 11 away from the lock head 12, the elastic arm 11 is opened outward to drive the lock head 12 connected with the elastic arm 11 to open outward, thereby separating from the locking structure 22 on the plug-in locking part 2a, so that the male buckle 1 and the female buckle 2 are in the unlocked state; at the same time, the female buckle 2 and the male buckle 1 are pulled apart in the opposite direction of the plug-in, so that the pulling force is greater than the mutual magnetic attraction force between the first magnetic attraction structure 4 and the second magnetic attraction structure 5, the male buckle 1 and the female buckle 2 are separated from each other, at this time, the reset of the unlocking operation member 3 is realized by the elastic member 7. Figure 9 The working principle of the magnetic fastener 100b of the third embodiment is the same as that of the magnetic fastener 100a of the second embodiment, which will not be described here.

[0067] Compared with the prior art, the magnetic fastener 100, 100a, 100b of the present application realizes the locking of the male buckle 1 and the female buckle 2 by the locking of the locking part 1a and the plug-in locking part 2a, and realizes the mutual magnetic attraction of the first magnetic attraction structure 4 on the male buckle 1 and the second magnetic attraction structure 5 on the female buckle 2 to keep the male buckle 1 and the female buckle 2 in the plug-in state, and the locking part 1a and the plug-in locking part 2a keep in contact state under the mutual repulsion of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, so that the magnetic fastener 100 of the present application makes the locking of the male buckle 1 and the female buckle 2 more reliable; at the same time, the mutual magnetic attraction of the first magnetic attraction structure 4 and the second magnetic attraction structure 5 makes the male buckle 1 and the female buckle 2 keep in the plug-in state and not automatically separated from each other even if the locking part 1a and the plug-in locking part 2a are unlocked due to the accidental touch of the unlocking operation member by the user or children, so that the safety is better, and the loss of the male buckle 1 and the female buckle 2 due to the unlocking of the locking part 1a and the plug-in locking part 2a is prevented. Alternatively, the mutual repulsion of the first magnetic attraction structure 4 and the second magnetic attraction structure 5 makes the male buckle 1 and the female buckle 2 automatically separated after the unlocking of the male buckle 1 and the female buckle 2, which is more convenient for the unlocking operation of the male buckle 1 and the female buckle 2; in addition, the magnetic fastener 100, 100a, 100b of the present application also has the advantage of compact structure.

[0068] The above-described embodiments are merely intended to illustrate the present application, but not to limit the scope of the present application. Any equivalent changes made in the light of the above-described embodiments should be construed as falling within the scope of the present application.
