A groove 15 is provided on the lower surface of the sub-button body 11 to facilitate the embedding of the female buckle body 21 into the sub-button body 11.

[0030] Among them Figure 7 and Figure 8 As shown, the female buckle 20 includes a female buckle body 21, and a second magnet slot 22 is provided on the lower surface of the female buckle body 21. An opening for placing a spring is provided between the second magnet slots 22. The spring provides elastic force for the two sliding buckles 53. A pair of positive and negative magnets are placed in the first magnet slot 14 and the second magnet slot 22. The two pairs of positive and negative magnets are arranged opposite to each other, which is convenient for realizing self-locking and locking operation by utilizing the principle of magnetic attraction and repulsion. The magnets are fixed by glue dripping operation. Female buckle fixing slots 23 are symmetrically provided on both sides of the second magnet slot 22. The shape and specifications of the female buckle body 21 are adapted to the shape and specifications of the groove 15 to ensure the normal use of the female buckle.

[0031] Among them Figure 1 and Figure 5 As shown, the buckle card cover 30 includes a top plate 31, and a placement groove 32 adapted to the protrusion 13 is opened on the surface of the top plate 31, which is convenient for embedding the protrusion 13 into the placement groove 32. Buckle fixing holes 33 are symmetrically arranged on both sides of the placement groove 32. The specifications and dimensions of the buckle fixing holes 33 are adapted to the specifications and dimensions of the buckle fixing block 12, which facilitates the snap-on operation and the fixing position.

[0032] Among them Figure 2 and Figure 9 As shown, the female buckle card cover 40 includes a base plate 41, and a recessed block 42 is provided on the upper surface of the base plate 41, which is convenient for confining the magnet between the recessed block 42 and the second magnet slot 22, and confining the spring inside the opening to avoid displacement. The magnet is fixed by the glue dripping operation to play a positioning role. The recessed block 42 and the base plate 41 are an integrated structure, and female buckle fixing blocks 43 are symmetrically provided on both sides of the recessed block 42. The specifications and dimensions of the female buckle fixing block 43 are adapted to the specifications of the female buckle fixing slot 23, so that the snap-on operation can be realized, which is convenient for fixing the position.

[0033] Among them Figure 4-Figure 8As shown, the sliding assembly 50 includes a cylindrical card body 51 symmetrically arranged on the inner wall of the groove 15, and the cylindrical card body 51 is fixedly connected to the inner wall of the groove 15. A movable groove 52 is symmetrically opened on the side wall of the female buckle body 21, which is convenient for use with the cylindrical card body 51. A sliding buckle 53 is provided inside the movable groove 52. The other end of the sliding buckle 53 is sleeved with a spring. The spring is restricted inside the opening between the second magnet slots 22. The sliding buckle 53 can be driven to return to its original position by the spring. A locking groove 54 is provided below the sliding buckle 53, and a slide-out groove 55 is provided on one side of the locking groove 54. The locking groove 54 It is connected to the slide-out groove 55. During the locking process, the two cylindrical card bodies 51 on the sub-buckle body 11 move downward along the moving groove 52, and then push open the sliding card buckle 53, so that the cylindrical card body 51 can smoothly enter the locking groove 54 to complete the locking. After locking, the sliding card buckle 53 returns to its original position, thereby preventing the cylindrical card body 51 from detaching. If the placement angle of the cylindrical card body 51 deviates, the two opposite magnetic poles in the sub-buckle body 11 and the mother buckle body 21 will automatically rotate to the correct angle through the action of suction and repulsion to assist the cylindrical card body 51 to push open the sliding card buckle 53, thereby realizing the locking operation with the mother buckle body 21.

[0034] Among them Figure 4 and Figure 7 As shown, the distance between the two side walls of the slide-out groove 55 is greater than the diameter of the cylindrical card body 51, which limits the size of the slide-out groove 55 to avoid interference. When the magnetic buckle needs to be separated, it is only necessary to pull up and rotate the sub-buckle body 11, and then make the cylindrical card body 51 inside the sub-buckle body 11 slide out through the slide-out groove 55 on one side of the mother buckle body 21, thereby completing the disengagement operation.

[0035] Among them Figure 4 As shown, a positioning protrusion 16 is fixedly provided inside the groove 15. The positioning protrusion 16 is set in a square or round shape and is used to limit the left and right positions of the sub-button and the mother buckle after locking.

[0036] Among them Figure 4 and Figure 7 As shown, a positioning protrusion groove 24 is provided on the top of the female buckle body 21. When the sub-buckle body 11 and the female buckle body 21 are locked by magnetic attraction, the positioning protrusion 16 will be engaged with the positioning protrusion groove 24 to prevent the sub-buckle body 11 and the female buckle body 21 from sliding left and right after locking, thereby playing a positioning role. The size specifications of the positioning protrusion 16 are compatible with the size specifications of the positioning protrusion groove 24. An anti-slip pad can be provided on the surface of the positioning protrusion groove 24 to increase the friction between the positioning protrusion 16 and the positioning protrusion groove 24, thereby improving the connection stability. When the magnetic buckle needs to be separated, the sub-buckle body 11 needs to be pulled upward to disengage the positioning protrusion 16 from the positioning protrusion groove 24.

[0037] When in use, first place the fabric layer of the surface to be closed of the first item on top of the buckle body 11, and embed the buckle fixing block 12 into the buckle fixing hole 33, and embed the protrusion 13 into the placement groove 32, thereby realizing the fixing operation of the buckle 10 and the buckle card cover 30, so as to achieve the effect of fixing the buckle 10 on the first item, and place the fabric layer of the surface to be closed of the second item on top of the bottom plate 41, and embed the female buckle fixing block 43 into the female buckle fixing groove 23, and embed the concave block 42 into the second magnet groove 22, so as to achieve the effect of fixing the female buckle 20 on the second item, thereby completing the assembly operation of the sub-buckle 10 and the female buckle 20, and make the sub-buckle 10 and the female buckle 20 correspond to each other, so that under the action of the magnetic attraction of the magnet, the two cylindrical card bodies 51 will push open the sliding buckle 53 and enter the locking groove 54. Since the sliding buckle 53 will return to its original state after locking, the limiting operation in the up and down directions is achieved.
