[0047] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0048] See also Figures 1 to 4 The magnetic fastener 100 of the first embodiment includes a male buckle 1, a female buckle 2, a release operating member 3, and first and second magnetic structures 4 and 5 that magnetically attract each other. The male buckle 1 has a locking portion 1a, and the female buckle 2 has a mating lock portion 2a that mates with the locking portion 1a. The first magnetic structure 4 is provided on the male buckle 1, and the second magnetic structure 5 is provided on the female buckle 2. When the male buckle 1 and female buckle 2 are inserted toward each other, the locking portion 1a engages with the mating lock portion 2a. During the insertion process, the first and second magnetic structures 4 and 5 magnetically attract each other, facilitating faster fastening of the male and female buckles 1 and 2. The release operating member 3 is movably provided on the male buckle 1. When the release operating member 3 selectively releases the locking portion 1a from the mating lock portion 2a, allowing the male and female buckles 1 and 2 to be separated, the first and second magnetic structures 4 and 5 magnetically attract each other, maintaining the mating state of the male and female buckles 1 and 2. Of course, in other embodiments, the first magnetic structure 4 provided on the male buckle 1 and the second magnetic structure 5 provided on the female buckle 2 can also be magnetically repelled, so that the first magnetic structure 4 and the second magnetic structure 5 can repel each other magnetically, so that the locking portion 1a and the mating lock portion 2a after buckling are kept in a state of mutual conflict, so that the buckling is more reliable, and the above example is not limited. 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 unlocking operating member 3 is moved along the plugging direction (such as Figure 4The outer cover 6 is movably placed on the outer cover 6 in the up and down direction shown in the figure. Preferably, the unlocking operating member 3 is a round button so that the user can release the locking portion 1a and the mating lock portion 2a from each other by pressing the unlocking operating member 3; the outer cover 6 is at one end in the mating direction (as shown in the figure). Figure 4 The upper end of the middle outer cover 6 is provided with a through hole 61 for the release operating member 3 to pass through. The outer cover 6 is provided at the other end in the insertion direction (such as Figure 4 The lower end of the middle outer cover 6 is provided with a mating hole 62 for mating the mating lock portion 2a. By means of the outer cover 6, the male buckle 1 and the female buckle 2 can be more stable during operation, and dust can be blocked, reducing the wear and tear caused by the outside world on the male buckle 1 and the female buckle 2, thereby correspondingly extending the service life of the magnetic buckle 100 of this embodiment, while being more beautiful and elegant. It is understandable that in other embodiments, the mating lock 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 unlocking operating member 3 is correspondingly provided on the female buckle 2. In addition, the outer cover 6 can be deleted according to actual needs, so it is not limited to the above example. More specifically, as follows:

[0049] Combine Figure 5 and Figure 6 The locking portion 1a is an elastic structure, and the mating lock portion 2a has a pushing structure 21 and a matching lock structure 22; during the mating process, the pushing structure 21 pushes the locking portion 1a and causes the locking portion 1a to produce elastic deformation, thereby causing the locking portion 1a to slide to a position locked with the matching lock structure 22, and the state is shown in FIG. Figure 4 As shown; the unlocking operating member 3 selectively drives the locking portion 1a to elastically deform and disengage from the locking with the matching lock structure 22. Therefore, by means of the pushing structure 21, the matching lock structure 22 is locked with the locking portion 1a more quickly and smoothly. Specifically, in this embodiment, the locking portion 1a includes an elastic arm 11 and a lock head 12 for locking with the matching lock structure 22. The lock head 12 is connected to the elastic arm 11. Preferably, the elastic arm 11 and the lock head 12 together form an integral structure, so that the lock head 12 is suspended in the middle of the male buckle 1 by means of the elastic arm 11. Figure 3As shown, the elastic arm 11 can more reliably drive the lock head 12 to move. The elastic arm 11 always has the tendency to drive the lock head 12 to lock with the matching lock structure 22. Therefore, during the insertion process, the pushing structure 21 pushes the lock head 12 to drive the elastic arm 11 to produce elastic deformation, thereby causing the lock head 12 to slide to a position locked with the matching lock structure 22, achieving the purpose of automatic locking of the male buckle 1 and the female buckle 2 during the insertion process. The release operating member 3 selectively drives the elastic arm 11 to perform elastic deformation, thereby causing the lock head 12 to break away from the lock with the matching lock structure 22. Preferably, the release operating member 3 pushes the elastic arm 11 in a direction parallel to the insertion direction, causing the elastic arm 11 to produce elastic deformation in a direction staggered with the insertion direction, thereby causing the lock head 12 to break away from the lock with the matching lock structure 22, so that the release process between the lock head 12 and the matching lock structure 22 is simple. For example, in this embodiment, there are two elastic arms 11 and they are arranged in an embracing and mating locking portion 2a, and each elastic arm 11 is connected to a lock head 12, so that the lock head 12 is arranged to surround the mating locking structure 22, so that the lock head 12 is more reliably locked with the mating locking structure 22, thereby making the fastening of the male buckle 1 and the female buckle 2 more stable and reliable; of course, in other embodiments, the number of elastic arms 11 can also be three, four or five, so it is not limited to this; preferably, the lock head 12 is selected to be a hook-shaped structure, and the mating locking structure 22 is a hook groove, so that the magnetic buckle 100 of this embodiment is more tightly fastened and not easy to disengage by the cooperation of the hook-shaped structure and the hook groove; at the same time, the male buckle 1 is a hollow structure, and the middle part of the male buckle 1 has a horizontal intermediate support arm 14, and the intermediate support arm 14 is located between the two elastic arms 11 and connected to the corresponding two side walls of the male buckle 1 to increase the strength of the male buckle 1.

[0050] See also Figures 3 to 6 The end of the pushing structure 21 has a relative insertion direction (such as Figure 4 The locking head 12 has a first inclined structure 211 inclined in the up and down directions (as shown), and the locking head 12 has a second inclined structure 121 that matches the first inclined structure 211; during the insertion process, the first inclined structure 211 pushes the second inclined structure 121, so that the pushing structure 21 can easily pass over the locking head 12 and slide to the position where the matching locking structure 22 and the locking head 12 are locked, thereby facilitating the locking of the male buckle 1 and the female buckle 2.

[0051] See also Figures 3 to 6The release operating member 3 has a push-up bevel 31 that is inclined relative to the insertion direction. The release operating member 3 pushes the elastic arm 11 via the push-up bevel 31 to cause elastic deformation, thereby disengaging the lock head 12 from the matching lock structure 22 and releasing the lock. Because the lock head 12 is arranged to surround the matching lock structure 22, the push-up bevel 31 is inclined from the inside to the outside in a direction away from the push-up bevel 31. The release operating member 3 pushes the elastic arm 11 via the push-up bevel 31 to cause elastic deformation, thereby causing the elastic arm 11 to push the lock head 12 outward and disengage from the matching lock structure 22. Of course, in other embodiments, the elastic arm 11 can also drive the lock head 12 inward and disengage from the matching lock structure 22, and the present invention is not limited to this. For example, in this embodiment, the release operating member 3 extends outwardly parallel to the insertion direction to form a spreading leg 32, and the push-up bevel 31 is formed on the spreading leg 32. The end of the spring arm 11 used to connect with the lock head 12 has a pushed inclined surface 111 that matches the pushing inclined surface 31. The lock release operating member 3 pushes the spring arm 11 to produce elastic deformation by the cooperation of the pushing inclined surface 31 and the pushed inclined surface 111, so that the lock head 12 is separated from the matching lock structure 21; preferably, the end of the spring arm 11 used to connect with the lock head 12 is provided with a groove 112, the spreading leg 32 is extended and placed in the groove 112, the pushed 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 lock release operating member 3 pushing the spring arm 11 to produce elastic deformation is simpler, and the spreading leg 32 directly acts on the groove 112 of the end connected to the lock head 12 to make the elastic deformation of the spring arm 11 faster, so that the lock head 12 and the matching lock structure 22 are separated faster, so it is not limited to this.

[0052] See also Figure 3 、 Figure 4 and Figure 6The male buckle 1 is provided with a first embedding cavity 13, and the female buckle 2 is provided with a second embedding cavity 23. The first magnetic structure 4 is embedded in the first embedding cavity 13, and the second magnetic structure 5 is embedded in the second embedding cavity 23, so that the first magnetic structure 4 is hidden in the male buckle 1, and the second magnetic 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 insertion direction to maximize the magnetic force between the first magnetic structure 4 and the second magnetic structure 5, thereby accelerating the insertion between the male buckle 1 and the female buckle 2. At the same time, the maximum magnetic attraction force is maintained between the male buckle 1 and the female buckle 2 after insertion, effectively preventing accidental separation between the male buckle 1 and the female buckle 2. For example, the second embedding cavity 23 is formed in the mating lock portion 2a, and the first embedding cavity 13 is formed in the middle of the male buckle 1, specifically in the middle of the middle support arm 14, so that the magnetic buckle 100 of the present invention makes reasonable use of space and saves materials; at the same time, the first magnetic structure 4 and the second magnetic structure 5 are each magnets; of course, in other embodiments, one of the first magnetic structure 4 and the second magnetic 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 structure 4 ranges from 3.0 to 5.5 mm, preferably 3.0, 3.8, 4.5, 5.0 or 5.5 mm. It is worth noting that when the mating lock portion 2a is formed on the male buckle 1, the first embedding cavity 13 is formed in the mating lock portion 2a.

[0053] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the female buckle 2 and the outer cover 6 each have an assembly end for assembling the braid. Preferably, the female buckle 2 has two assembly ends arranged opposite each other, and the outer cover 6 has one assembly end that is always arranged opposite to any assembly end on the female buckle 2, so as to facilitate the assembly of the braid. For example, the assembly ends of the female buckle 2 and the outer cover 6 are provided with through holes 24 and 63 for the braid to pass through. The female buckle 2 can be fixed to the first fabric surface (not shown) by its two assembly ends and the braid passing through the two assembly ends, and the male buckle 1 can be fixed to the braid connected to the second fabric surface (not shown) by the assembly end of the outer cover 6, thereby achieving a detachable connection between the first fabric surface and the second fabric surface. In other embodiments, the mating lock portion 2a is a cylindrical structure, allowing the male buckle 1 and the female buckle 2 to selectively rotate about the mating lock portion 2a, thereby making the operation of the male buckle 1 and the female buckle 2 more flexible. At the same time, any assembly end of the female buckle 2 can be used together with the assembly end on the outer cover 6 after rotation. If one assembly end of the female buckle 2 is damaged, the other assembly end can be used together with the assembly end on the outer cover 6 by rotating the female buckle 2, thereby improving the durability of the magnetic buckle 100 of the present invention.

[0054] See also Figures 7 to 10The second embodiment shown, the magnetic fastener 100a of this embodiment is basically the same as the first embodiment, with the following differences:

[0055] First, in this embodiment, ribs 64 are protruding from the outer cover 6, and the ribs 64 are located on the side walls of the outer cover 6. Preferably, the ribs 64 are located on the two opposite side walls of the outer cover 6. The ribs 64 increase the friction resistance to facilitate the operator to operate the magnetic buckle 100a. In the first embodiment, the outer cover 6 does not have ribs 64.

[0056] Second, the inclined pushing surface 31 of the spreading leg 32 of this embodiment pushes against the end of the elastic arm 11 away from the lock head 12, directly applying force to the end of the elastic arm 11 away from the lock head 12 by the inclined pushing surface 31 of the spreading leg 32. That is, the spreading leg 32 is located between the elastic arm 11 and the intermediate support arm 14. Therefore, the elastic arm 11 of this embodiment does not have a pushed inclined surface 111 or a groove 112 that cooperates with the inclined pushing surface 31. Because the spreading legs 32 of this embodiment are arranged in pairs and spaced apart, the intermediate support arm 14 is retained in the gap between the paired spreading legs 32.

[0057] Third, since the pushing inclined surface 3 of the spreading leg 32 of this embodiment directly applies force to the end of the elastic arm 11 away from the lock head 12, in order to make the release operating member 3 more reliably reset, the magnetic buckle 100a of this embodiment also includes an elastic member 7 that provides elastic force for resetting the release operating member 3. The elastic member 7 is preferably a spring. Of course, it can be designed as an elastic plastic or other structure according to actual needs; and the elastic member 7 is in contact between the release operating member 3 and the male buckle 1, but is not limited to this; and in the first embodiment, since the pushing inclined surface 31 of the spreading leg 32 applies force to the end of the elastic arm 11 connected to the lock head 12, the reset of the release operating member 3 is achieved by the elastic arm 11.

[0058] Fourth, in this embodiment, the thickness of the first magnetic structure 4 is 5.0 mm, while in the first embodiment, the thickness of the first magnetic structure 4 is 3.8 mm.

[0059] Except for the above differences, other aspects are the same as those of the first embodiment, and therefore will not be described again.

[0060] See also Figures 11 to 13 In the third embodiment shown, the structure of the magnetic fastener 100b of this embodiment is substantially the same as that of the magnetic fastener 100a of the second embodiment, with the following differences:

[0061] First, in this embodiment, the unlocking operating member 3 is a square button; whereas in the second embodiment, the unlocking operating member 3 is a round button.

[0062] Second, in this embodiment, the outer cover 6 does not have ribs 64 protruding therefrom; whereas in the second embodiment, the outer cover 6 does have ribs 64 protruding therefrom.

[0063] Third, in this embodiment, the elastic member 7 abuts against the unlocking operating member 3 and the male buckle 1 and deviates from the first embedding cavity 13 ; whereas in the second embodiment, the elastic member 7 abuts against the unlocking operating member 3 and the male buckle and faces the first embedding cavity 13 .

[0064] Except for the above differences, everything else is the same as the second embodiment, so it will not be described again here.

[0065] Combine Figures 1 to 6 , the working principle of the magnetic fastener 100 of the first embodiment of the present invention is explained as follows: when the magnetic fastener 100 of this embodiment is to be switched from the locked state to the released state, the release operating member 3 of the release operating member 3 is pressed downward, and the spreading leg 32 below the release operating member 3 contacts the groove 112 of the elastic arm 11 and pushes the groove 112, thereby the elastic arm 11 is spread outward by the cooperation of the pushing inclined surface 31 on the spreading leg 32 and the pushed inclined surface 111 on the groove 112, thereby driving the lock head 12 connected to the elastic arm 11 to spread outward together, thereby disengaging from the locking structure 22 on the mating locking portion 2a, thereby putting the male buckle 1 and the female buckle 2 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 mating, 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 separation of the male buckle 1 and the female buckle 2. When the male buckle 1 and the female buckle 2 are to be fastened together, the mating lock portion 2a is first aligned with the mating 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 mating lock portion 2a easily passes over the lock head 12, so that the mating lock structure 22 and the lock head 12 are locked with each other, and the male buckle 1 and the female buckle 2 are locked together. Figure 4 shown.

[0066] Combine Figures 7 to 10, the working principle of the magnetic fastener of the second embodiment is explained as follows: when the magnetic fastener 100a of this embodiment is to be switched from the locked state to the released state, the release operating member 3 is pressed downward to put the elastic member 7 in a compressed state, and the pushing inclined surface 31 of the spreading leg 32 below the release operating member 3 directly applies force to the end of the elastic arm 11 away from the lock head 12, so that the elastic arm 11 is spread outward and drives the lock head 12 connected to the elastic arm 11 to be spread outward together, thereby disengaging from the locking structure 22 on the mating locking portion 2a, thereby putting the male buckle 1 and the female buckle 2 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 insertion, 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, so that the male buckle 1 and the female buckle 2 are separated from each other, and the reset of the release operating member 3 is achieved by the elastic member 7. When the male buckle 1 and the female buckle 2 are to be fastened together, the mating lock portion 2a is first aligned with the mating 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 mating lock portion 2a easily passes over the lock head 12, so that the mating lock structure 22 and the lock head 12 are locked with each other, and the male buckle 1 and the female buckle 2 are locked together. Figure 9 Since 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, it will not be described in detail here.

[0067] Compared with the prior art, the magnetic buckle 100, 100a, 100b of the present invention realizes the locking of the male buckle 1 and the female buckle 2 by locking the locking portion 1a with the mating locking portion 2a, and then 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 are magnetically attracted to each other, so that the male buckle 1 and the female buckle 2 are kept in the mating state. Under the mutual repulsion of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, the locking portion 1a and the mating locking portion 2a are kept in the state of mutual conflict. Therefore, the magnetic buckle of the present invention is The magnetic fastener 100 makes the fastening between the male buckle 1 and the female buckle 2 more reliable. At the same time, due to the mutual magnetic attraction of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, even if the user or child accidentally touches the unlocking operating member and causes the locking portion 1a and the mating locking portion 2a to be unlocked, the male buckle 1 and the female buckle 2 will remain in the mating state and will not automatically separate from each other, thereby improving safety. It can also prevent the male buckle 1 and the female buckle 2 from falling and being lost due to the unlocking between the locking portion 1a and the mating locking portion 2a. Alternatively, due to the mutual repulsion of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, after the male buckle 1 and the female buckle 2 are unlocked, the male buckle 1 and the female buckle 2 will automatically separate, making the unlocking operation of the male buckle 1 and the female buckle 2 easier. In addition, the magnetic fasteners 100, 100a, and 100b of the present invention also have the advantage of being compact.

[0068] The above disclosure is only a preferred embodiment of the present invention and cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are within the scope of the present invention.
