[0027] Please refer to Figures 1 to 4The magnetic buckle in Example 1 of the utility model includes a first bending arm 10, one end of the first bending arm 10 is connected to a first buckle seat 20, the other end of the first bending arm 10 is rotatably connected to a second bending arm 30, and one end of the second bending arm 30 away from the first bending arm 10 is connected to a second buckle seat 40, and the first bending arm 10 and the second bending arm 30 are both arc-shaped to adapt to the shape of the wrist. Specifically, the first bending arm 10 is provided with an avoidance groove 110, and the avoidance groove 110 is used to accommodate the second bending arm 30 when the second buckle seat 40 is buckled on the first buckle seat 20. The side walls opposite to the avoidance groove 110 are connected with a rotating shaft 120, and the rotating shaft 120 is located at the end of the first bending arm 10 facing away from the first buckle seat 20, and the end of the second bending arm 30 facing the first bending arm 10 is sleeved on the rotating shaft 120, that is, when buckling is required, the second bending arm 30 is axially positively moved along the rotating shaft 120 through the second bending arm 30. The first buckle 10 and the second buckle 30 are rotated in the opposite direction to make the second buckle 40 approach the first buckle 20. At this time, the second bending arm 30 is gradually accommodated in the avoidance groove 110, that is, the first bending arm 10 and the second bending arm 30 overlap, shrink and sleeve on the wrist. When it is necessary to release, the second bending arm 30 is rotated in the opposite direction along the axial direction of the rotating shaft 120, the first buckle 20 is disengaged from the second buckle 40, and the second bending arm 30 is gradually disengaged from the avoidance groove 110. After the first bending arm 10 and the second bending arm 30 are offset, they are unfolded and disengaged from the wrist.

[0028] The first buckle seat 20 has a concave surface facing away from the first bending arm 10 to form a first card interface, and the first card interface is detachably connected to the first strap 90. The second buckle seat 40 has a concave surface facing away from the second bending arm 30 to form a second card interface, and the second card interface is detachably connected to the second strap 100. The detachable connection between the first card interface and the first strap 90 and the detachable connection between the second card interface and the second strap 100 can be achieved through a buckle structure or a magnetic structure, which will not be described in detail here. It can be understood that the end of the first strap 90 facing away from the first buckle seat 20 is detachably connected to one end of the dial, and the end of the second strap 100 facing away from the second buckle seat 40 is detachably connected to the end of the dial facing away from the first strap 90.

[0029] One side of the first fastening seat 20 is recessed to form a receiving groove, and a partition plate 210 is arranged in the receiving groove to divide the receiving groove into a bearing groove 220 and a placing groove 230 which are distributed from top to bottom. One side of the second fastening seat 40 is connected with a first magnetic component 50. The bearing groove 220 is used for receiving the first magnetic component 50. After the first fastening seat 20 approaches the second fastening seat 40, the first magnetic component 50 is received in the bearing groove 220. In this embodiment, the second fastening seat 40 is rotatably connected to the second bending arm 30 to improve the flexibility of the second fastening seat 40 and make the fastening smoother. Specifically, one side of the second fastening seat 40 facing the second bending arm 30 is connected with a relatively arranged first support block 410 and a second support block. One end of the second bending arm 30 facing the second fastening seat 40 is sleeved with a support rod 420, and two opposite ends of the support rod 420 are respectively rotatably connected to the first support block 410 and the second support block.

[0030] An adaptation component 60 is arranged in the placing groove 230. The adaptation component 60 includes a second magnetic component 610, a third magnetic component 620 and a first magnetic isolation plate 630. A first magnetic isolation plate 630 is arranged between the second magnetic component 610 and the third magnetic component 620. The first magnetic component 50 and the second magnetic component 610 have the same magnetic property, and the first magnetic component 50 and the third magnetic component 620 have opposite magnetic properties, that is, the magnetic fields between the first magnetic component 50 and the second magnetic component 610 repel each other, and the magnetic fields between the first magnetic component 50 and the third magnetic component 620 attract each other. A partition space is formed between the adaptation component 60 and the partition plate 210, and a second magnetic isolation plate 640 is slidably connected in the partition space. The second magnetic isolation plate 640 is used to isolate the magnetic field between the second magnetic component 610 and the first magnetic component 50 or isolate the magnetic field between the third magnetic component 620 and the first magnetic component 50.

[0031] When it is necessary to fasten the magnetic snap, by means of the rotational connection between the first bending arm 10 and the second bending arm 30, the second snap seat 40 is brought close to the first snap seat 20, the second magnetic shielding plate 640 is placed on the top of the second magnetic component 610, and due to the opposite magnetic characteristics between the first magnetic component 50 and the third magnetic component 620, the second snap seat 40 is adsorbed on the first snap seat 20 to complete the fastening. By providing the receiving groove 220, the first magnetic component 50 on the second snap seat 40 is received in the receiving groove 220, which can make the fastening more aesthetic. At the same time, the receiving groove 220 limits the first magnetic component 50 to prevent the first magnetic component 50 from moving, improving the fastening stability between the first snap seat 20 and the second snap seat 40. When it is necessary to unfasten, only the second magnetic shielding plate 640 needs to be moved so that the second magnetic shielding plate 640 is placed on the top of the third magnetic component 620 to isolate the adsorption between the first magnetic component 50 and the third magnetic component 620. And due to the same magnetic characteristics between the second magnetic component 610 and the first magnetic component 50, the first magnetic component 50 is ejected from the receiving groove 220, and then the first snap seat 20 and the second snap seat 40 are unfastened. There is no need to resist the magnetic attraction by manpower, greatly reducing the difficulty of unfastening and improving the user experience.

[0032] Preferably, a magnetic shielding limiting plate 70 is provided in the partition space. The magnetic shielding limiting plate 70 is located at the top of the end of the third magnetic component 620 facing away from the second magnetic component 610. The width of the second magnetic shielding plate 640 is greater than the sum of the widths of the second magnetic component 610 and the first magnetic shielding plate 630. The widths of the second magnetic component 610 and the third magnetic component 620 are the same. When the first magnetic component 50 is placed in the receiving groove 220 and magnetically adsorbed to the third magnetic component 620, the magnetic shielding limiting plate 70 can limit the vertical movement of the third magnetic component 620 to prevent it from moving into the partition space due to the suction force. Further, through the width design of the second magnetic shielding plate 640, the second magnetic shielding plate 640 can limit the third magnetic component 620 at the end of the third magnetic component 620 facing away from the magnetic shielding limiting plate 70. Through the cooperation between the second magnetic shielding plate 640 and the magnetic shielding limiting plate 70, the limiting is more stable.

[0033] The side wall of the first buckle seat 20 is concave to form an adjustment groove 240, and the adjustment groove 240 is connected to the partition space. The side wall of the second magnetic isolation plate 640 is connected to the adjustment block 641. The end of the adjustment block 641 facing away from the second magnetic isolation plate 640 passes through the adjustment groove 240 and protrudes outside the first buckle seat 20. It can be understood that by moving the adjustment block 641 along the adjustment groove 240, the position of the second magnetic isolation plate 640 can be changed. In this embodiment, because the first magnetic attraction member 50 and the second magnetic attraction member 610 only need to generate a magnetic effect when they are released, the adjustment groove 240 corresponds to the position of the third magnetic attraction member 620. The second magnetic isolation plate 640 is moved from the second bending arm 30 toward the second strap 100 and abuts against the magnetic isolation limit plate 70. At this time, the magnetic isolation limit plate 70 cooperates with the second magnetic isolation plate 640 to completely isolate the magnetic field of the third magnetic member 620, so that the first magnetic member 50 and the second magnetic member 610 are repelled and disengaged. When it is necessary to engage, the second magnetic isolation plate 640 is moved from the second strap 100 toward the second bending arm 30, and the magnetic field of the second magnetic member 610 is isolated, and the first magnetic member 50 and the third magnetic member 620 are attracted and engaged. Furthermore, a reset spring 80 is arranged in the adjustment groove 240, one end of the reset spring 80 is connected to the adjustment block 641, and the other end of the reset spring 80 is connected to the side wall of the adjustment groove 240. By setting the reset spring 80, when the second magnetic isolation plate 640 is placed on the top of the third magnetic attraction component 620, after the magnetic isolation is released, the second magnetic isolation plate 640 can be reset and re-positioned above the second magnetic attraction component 610 without manual operation, thereby improving the portability of use and further enhancing the user's usage experience.
