By setting the magnetic buckle as two male buckles 1 and female buckles 2 parts, which are fixed to the objects respectively, and then the clamping mechanism 25 provided in the female buckle 2 can clamp and unlock the magnet block 102 in the male buckle 1, thereby realizing the opening and closing operation of the magnetic buckle, which is convenient and quick. At the same time, the material used for the female buckle 2 is steel, which can make the magnetic buckle effortless when unlocking, and solves the problem that the original magnetic buckle needs to be adsorbed with a magnetic tool to help the unlocking operation, or the male buckle 1 and the female buckle 2 are adsorbed and connected by the magnetic material to generate suction, which is inconvenient for the user to unlock the magnetic buckle and is more laborious.

[0021] The clamping mechanism 25 includes a clamping block 251, two clamping blocks 251 are provided, and an arc-shaped opening 252 used in conjunction with the magnet block 102 is provided on one side opposite to the two clamping blocks 251, and a spring piece 253 is integrally formed at a symmetrical position on the other side of the clamping block 251, and one end of the spring piece 253 away from the clamping block 251 is connected to the inner wall of the upper cover 22, and a clamping groove 254 is provided at a symmetrical position on the surface of the upper cover 22, and an extrusion block 255 used in conjunction with the clamping block 251 is installed in the inner cavity of the clamping groove 254, and the fitting surfaces of the extrusion block 255 and the clamping block 251 are both set as beveled surfaces, and the clamping block 251 is provided 251 and an arc-shaped opening 252 is provided at the position where the card block 251 and the magnetic buckle are engaged, in order to fix the magnet block 102 when engaged, a card slot 254 and an extrusion block 255 are provided on the upper cover 22 at the same time, in order to facilitate the user to push the card block 251 by applying force to the extrusion block 255, so that the spring piece 253 on the card block 251 is deformed in the upper cover 22, so that the card block 251 releases the engaging force on the magnet block 102, thereby separating the magnet block 102 from the card block 251, thereby completing the operation of quickly unlocking the magnetic buckle, which is convenient and simple.

[0022] A slide groove 3 is provided at the center of the surface of the block 251, and a slider 4 is fixedly connected to the inner wall of the upper cover 22 at a position corresponding to the slide groove 3. The slider 4 is slidably connected in the slide groove 3. The cooperation between the slider 4 and the slide groove 3 can provide a limiting effect on the moving position of the block 251, thereby ensuring the stability of the movement of the block 251.

[0023] A limiting groove 5 is provided on the inner surface of the extrusion block 255, and a limiting block 6 is fixedly connected to the position of the inner wall of the upper cover 22 corresponding to the movable groove. The lower end of the limiting block 6 is located in the limiting groove 5 and is movably connected. Through the cooperation of the set limiting groove 5 and the limiting block 6, in order to limit the movement of the extrusion block 255 under force, the position of the clamping block 251 can be quickly pushed. The limiting block 6 is set at a position close to the clamping groove 254, and the surface of the outer end of the extrusion block 255 is clamped with the clamping groove 254 to limit the extrusion block 255 during its activity.

[0024] A positioning column 7 used in conjunction with the magnet block 102 is fixedly connected at the center of the inner wall of the upper cover 22. The arc-shaped opening 252 on the clamping block 251 corresponds to the position of the positioning column 7. The material of the positioning column 7 is set to steel, which can not only produce an adsorption and limiting effect between the magnet blocks 102, but also facilitate the portability when the magnet block 102 is directly detached from the female buckle 2 without much effort.

[0025] The positioning assembly 23 includes a positioning rod 231, and four positioning rods 231 are provided. One end of the four positioning rods 231 is fixed to the inner wall of the upper cover 22. Four positioning grooves 232 are opened at positions on the surface of the base 21 corresponding to the four positioning rods 231. The lower end of the positioning rod 231 is clamped in the positioning groove 232. Through the cooperation of the set positioning rod 231 and the positioning groove 232, the upper cover 22 can be installed on the base 21, which not only provides protection for the clamping mechanism 25, but also forms a complete female buckle 2 structure.

[0026] The four positioning rods 231 are distributed around the positioning column 7, and the four positioning slots 232 are opened around the through hole 24, so that the force is evenly distributed, which can enhance the firmness of the connection between the upper cover 22 and the base 21.

An arc groove 9 is provided on the upper cover 22 at a position corresponding to the arc strip 8. The cooperation of the arc strip 8 and the arc groove 9 can provide a limiting effect when the upper cover 22 and the base 21 are closed.

[0028] The other end of the surface of the base 21 is fixedly connected to a right-angle bar 10 at a symmetrical position, and the right-angle bar 10 is clamped at two corners on the upper cover 22. By setting the right-angle bar 10, the stability of the installation position and the limiting effect between the upper cover 22 and the base 21 can be further enhanced.

[0029] When in use, first install the clamping mechanism 25 in the upper cover 22 and clamp it with the base 21 through the positioning assembly 23. When the lower magnetic buckle needs to be locked, it is only necessary to insert the magnet block 102 directly into the upper cover 22 through the through hole 24 on the base 21, and lock it through the clamping block 251 to complete the locking operation between the magnetic buckles. When the magnetic buckle needs to be unlocked, the user only needs to press the squeezing blocks 255 on both sides to move the squeezing blocks 255 inward, thereby squeezing and pushing the clamping block 251, and then the spring piece 253 on the clamping block 251 is deformed, which will drive the clamping block 251 to leave the position of clamping the magnet block 102, so that the magnet block 102 is separated from the arc-shaped opening 252 of the clamping block 251, and the magnet block 102 can be moved out. Not only is the operation simple, but the structure is also simple, which is convenient to manufacture and reduces the cost, and the magnet block 102 is effortless to detach.
