The unlocking operation member 3 is movably provided on the pin 1. When the release operation member 3 selectively releases the lock between the locking portion 1a and the opposite insertion locking portion 2a to allow the male buckle 1 and the female buckle 2 to be pulled out of each other, the first magnetic attraction structure 4 and the second magnetic attraction structure 5 at this time magnetically attract each other to keep the male buckle 1 and the female buckle 2 in the opposite insertion state. Of course, in other embodiments, the first magnetic attraction structure 4 disposed on the male buckle 1 and the second magnetic attraction structure 5 disposed on the female buckle 2 can also be magnetically repelled, so that the first magnetic attraction structure 4 and the second magnetic attraction structure 5 are magnetically repelled to each other, so that the locked locking portion 1a and the opposite-insertion locking portion 2a are kept in a mutual interference state, and the locking is more reliable, and the above example is not limited. Specifically, in the present embodiment, the magnetic buckle 100 of the present embodiment further includes an outer cover 6, the male buckle 1 is disposed in the outer cover 6, and the lock releasing operation member 3 movably penetrates the outer cover 6 along the opposite insertion direction (the up-down direction shown in fig. 4), preferably, the lock releasing operation member 3 is a circular button, so that the user can mutually release the locking portion 1a and the opposite insertion locking portion 2a by pressing the lock releasing operation member 3; the outer cover 6 has a through hole 61 for passing the lock releasing operation member 3 at one end in the opposite insertion direction (e.g., the upper end of the outer cover 6 in fig. 4), and the outer cover 6 has an opposite insertion hole 62 for inserting the lock part 2a in the opposite insertion direction (e.g., the lower end of the outer cover 6 in fig. 4), so that the outer cover 6 can block dust while the male buckle 1 and the female buckle 2 are more stable in operation, thereby reducing the external wear on the male buckle 1 and the female buckle 2, correspondingly prolonging the service life of the magnetic buckle 100 of the present embodiment, and being more beautiful and elegant. It is understood that, in other embodiments, the opposite insertion locking part 2a may be formed on the male buckle 1, and the locking part 1a may be formed on the female buckle 2; when the locking portion 1a is formed on the female buckle 2, the lock 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 that the above-mentioned example is not limited.

Therefore, the pushing structure 21 enables the locking structure 22 to be locked with the locking portion 1a more quickly and smoothly. Specifically, in the present embodiment, the locking portion 1a includes the elastic arm 11 and the lock head 12 for locking with the locking structure 22, and 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 at the middle portion of the pin 1 by the elastic arm 11, as shown in fig. 3, so that the elastic arm 11 can more reliably drive the lock head 12 to move. The elastic arm 11 always has the tendency of driving the lock head 12 and the lock matching structure 22 to be locked with each other; therefore, in the opposite insertion process, the pushing structure 21 drives the elastic arm 11 to generate elastic deformation by pushing the lock head 12, so that the lock head 12 slides to the position locked with the locking structure 22, and the purpose of automatically locking the male buckle 1 and the female buckle 2 in the opposite insertion process is realized; the release operation member 3 selectively drives the elastic arm 11 to elastically deform, so that the lock head 12 is separated from the lock matching structure 22, preferably, the release operation member 3 pushes the elastic arm 11 along a direction parallel to the opposite insertion direction, so that the elastic arm 11 elastically deforms along the direction crossing the opposite insertion direction to separate the lock head 12 from the lock matching structure 22, so that the lock releasing process between the lock head 12 and the lock matching structure 22 is simple and rapid. For example, in the present embodiment, the two elastic arms 11 are arranged in an encircling manner and are opposite to the insertion matching lock portions 2a, and each elastic arm 11 is connected with the lock head 12, so that the lock head 12 is arranged in an encircling manner around the matching lock structure 22, and thus the lock head 12 is more reliably locked with the matching lock structure 22, and the buckling between 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 may also be three, four or five, and is not limited thereto; preferably, the lock head 12 is a hook-shaped structure, and the locking structure 22 is a hook groove, so that the magnetic buckle 100 of the present embodiment is more tightly fastened and is not easily disengaged by the cooperation of the hook-shaped structure and the hook groove; meanwhile, the male buckle 1 is of a hollow structure, the middle part of the male buckle 1 is provided with a transverse middle supporting arm 14, and the middle supporting arm 14 is positioned between the two elastic arms 11 and connected to two corresponding side walls of the male buckle 1 so as to increase the strength of the male buckle 1.
Referring to fig. 3 to 6, the end of the pushing structure 21 has a first inclined structure 211 inclined with respect to the opposite insertion direction (the up-down direction shown in fig. 4), and the lock head 12 has a second inclined structure 121 matching with the first inclined structure 211; in the inserting process, the pushing structure 21 easily goes over the lock head 12 by the pushing of the first inclined structure 211 to the second inclined structure 121, and the pushing structure 21 slides to the position where the locking structure 22 and the lock head 12 are locked, so as to facilitate the locking of the male buckle 1 and the female buckle 2.
Referring to fig. 3 to 6, the unlocking operation member 3 has a pushing inclined surface 31 inclined relative to the opposite insertion direction, and the locking operation member 3 pushes the elastic arm 11 to generate elastic deformation by the pushing inclined surface 31, so that the lock head 12 is separated from the lock-matching structure 22 to unlock. Because the lock head 12 is arranged around the lock matching structure 22, the pushing inclined surface 31 is inclined from inside to outside along the direction far away from the pushing structure 21, the lock releasing operation part 3 pushes the elastic arm 11 to make expanding elastic deformation by the pushing inclined surface 31, and the elastic arm 11 drives the lock head 12 to be separated from the lock matching structure 22 outwards; of course, in other embodiments, the lock head 12 may be driven by the elastic arm 11 to disengage from the lock structure 22, and is not limited thereto. For example, in the present embodiment, the unlocking manipulating member 3 extends outward to form the spreading leg 32 in a direction parallel to the inserting direction, and the pushing inclined surface 31 is formed on the spreading leg 32. One end of the elastic arm 11, which is used for being connected with the lock head 12, is provided with a pushed inclined surface 111 matched with the pushing inclined surface 31, and the unlocking operation piece 3 pushes the elastic arm 11 to generate elastic deformation by the matching of the pushing inclined surface 31 and the pushed inclined surface 111 so as to separate the lock head 12 from the lock matching structure 21; preferably, the end of the elastic arm 11 used for connecting with the lock head 12 is provided with a groove 112, the spreading leg 32 extends into the groove 112, the pushed inclined plane 111 is formed on the groove wall surface of the groove 112, and the pushing inclined plane 31 is formed on the end surface of the spreading leg 32, so that the structure that the lock releasing operation member 3 pushes the elastic arm 11 to generate elastic deformation is simpler, the spreading leg 32 directly acts on the groove 112 at the end connected with the lock head 12 to enable the elastic deformation of the elastic arm 11 to be faster, and the lock head 12 and the lock matching structure 22 to be separated faster, thereby not being limited thereto.
Referring to fig. 3, 4 and 6, the male buckle 1 has a first embedding cavity 13, the female buckle 2 has 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, such 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, first inlay and establish chamber 13 and inlay along inserting the direction and establishing chamber 23 with the second and align to make first magnetism inhale structure 4 and second magnetism inhale the magnetic force between the structure 5 the biggest, thereby make the antithetical couplet between pin 1 and the box 2 insert more fast, make simultaneously and keep a biggest magnetic attraction between pin 1 and the box 2 after inserting, prevent unexpected the breaking away from between pin 1 and the box 2 effectively. For example, the second embedding cavity 23 is formed in the opposite insertion lock part 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 has reasonable space utilization and material saving; meanwhile, the first magnetic attraction structure 4 and the second magnetic attraction structure 5 are magnets respectively; 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 thereto; preferably, the thickness of the first magnetic attraction structure 4 is in a range of 3.0 to 5.5 mm, preferably 3.0, 3.8, 4.5, 5.0 or 5.5 mm. Note that, when the opposite insertion-fit lock portion 2a is formed on the pin 1, the first embedding cavity 13 is formed in the opposite insertion-fit lock portion 2a at this time.
As shown in fig. 1, 2, 3 and 5, the female buckle 2 and the outer cover 6 each have an assembly end for assembling a braid. Preferably, the equipment end on the box 2 is two and the relative disposition, and the equipment end on the enclosing cover 6 is one and all the time with arbitrary equipment end back to back arrangement on the box 2 to the equipment of braid over braid. For example, the assembling ends of the female buckle 2 and the outer cover 6 are provided with through holes 24 and 63 for the woven belt to pass through, the female buckle 2 can be fixed on a first cloth surface (not shown) by the two assembling ends on the female buckle and the woven belt passing through the two assembling ends, and the male buckle 1 can be fixed on a second cloth surface (not shown) by the assembling end of the outer cover 6 and the woven belt connected on the second cloth surface, so that the first cloth surface and the second cloth surface can be detachably combined. In other embodiments, the opposite-inserting-matching-locking part 2a has a cylindrical structure, so that the male buckle 1 and the female buckle 2 can selectively rotate around the opposite-inserting-matching-locking part 2a, the work of the male buckle 1 and the female buckle 2 is more flexible, and meanwhile, any assembling end on the female buckle 2 can be used together with the assembling end on the outer cover 6 after rotating.

When the male buckle 1 is to be buckled with the female buckle 2, the opposite-insertion-fit lock portions 2a are first aligned with the opposite-insertion holes 62 in the outer cover 6; then, the male buckle 1 and the female buckle 2 are mutually close, and under the mutual magnetic attraction action 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 locking structure 22 and the lock head 12 are mutually locked, and the locking of the male buckle 1 and the female buckle 2 is realized, and the state is shown in fig. 9. Since the operation principle of the magnetic buckle 100b of the third embodiment is the same as that of the magnetic buckle 100a of the second embodiment, it is not described herein again.
Compared with the prior art, the magnetic buckle 100, 100a, 100b of the invention realizes the locking of the male buckle 1 and the female buckle 2 by the locking of the locking part 1a and the opposite insertion locking part 2a, and then realizes the opposite insertion state of the male buckle 1 and the female buckle 2 by the mutual magnetic adsorption of the first magnetic attraction structure 4 arranged on the male buckle 1 and the second magnetic attraction structure 5 arranged on the female buckle 2, and the locking part 1a and the opposite insertion locking part 2a keep the mutual interference state under the mutual repulsion of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, so the magnetic buckle 100 of the invention ensures the more reliable buckling between the male buckle 1 and the female buckle 2; meanwhile, by the mutual magnetic attraction of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, even when a user or a child touches the lock release operation member to release the lock between the locking part 1a and the opposite insertion and matching locking part 2a, the male buckle 1 and the female buckle 2 are still in the opposite insertion state and cannot be automatically separated from each other, so that the safety is better, and the possibility of loss caused by the fact that the male buckle 1 and the female buckle 2 drop everywhere due to the lock release between the locking part 1a and the opposite insertion and matching locking part 2a can be prevented. Or, by mutual repulsion between the first magnetic attraction structure 4 and the second magnetic attraction structure 5, after the lock is released between the male buckle 1 and the female buckle 2, the male buckle 1 and the female buckle 2 are automatically separated at the moment, and the releasing operation of the male buckle 1 and the female buckle 2 is further performed; in addition, the magnetic buckles 100, 100a and 100b of the present invention also have the advantage of compact structure.
The above disclosure is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, so that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
