Example of implementation

[0010] An embodiment of the present invention will be explained in more detail below with reference to the drawings.

[0011] As in the Fig.Figures 1 to 6 show a magnetic suction buckle comprising a lower buckle and an upper buckle 1, the upper buckle 1 being provided on both sides with a pressing device for releasing the upper buckle 1 from the lower buckle, the pressing device comprising a pressing insert 21 and a buckle body 22 connected to the pressing insert 21, the buckle body 22 being used for connection with the lower buckle, a connecting element being provided between the buckle body 22 and the pressing insert 21, which can cause the buckle body 22 to move towards the interior of the upper buckle 1 when the pressing insert 21 is compressed towards the center of the upper buckle 1 to release the upper buckle 1 and the lower buckle, and the connecting element comprising a first movable block 23 and a second movable block 24 opposite each other.wherein the second movable block 24 is connected to the buckle body 22, wherein the first movable block 23 can drive the second movable block 24 to movement by force when the press insert 21 is compressed towards the center of the upper buckle 1, and wherein the second movable block 24 is provided with an elastic U-shaped element 25 which deforms when the second movable block 24 is subjected to a force to drive the second movable block 24 to movement. The present utility model moves towards the center of the upper buckle 1 by pressing on the press insert 21, which causes the first movable block 23 to move, deforms the elastic U-shaped element 25 and exerts the corresponding force on the second movable block 24, so that the second movable block 24 moves and thus releases; the present utility model incorporates the elastic U-shaped element 25,Because only one folding occurs, so that during the force application process the elastic U-shaped element 25 does not deform too much, leading to breakage, the press can still operate normally more than 10,000 times in actual use, resulting in better safety and performance.

[0012] In particular, a first magnet 11 is provided inside the center of the upper buckle 1, wherein a connecting opening 12 is provided directly below the first magnet 11, and wherein a second magnet 26, projecting outwards, is provided in the center of the lower buckle, and wherein a clamping slot 27 is provided on the outer side wall of the second magnet 26 to create a clamping connection with the buckle body 22.

[0013] To further prevent the elastic U-shaped element 25 from breaking under the force, the position of the second movable block 24 is lower in the vertical direction than the position of the first movable block 23, and the second movable block 24 is slightly offset relative to the first movable block 23; for the second movable block 24, part of the force exerted on it by the first movable block 23 can be eliminated, and at the same time the second movable block 24 can be brought closer to the inside of the lower buckle, which further prevents the elastic U-shaped element 25 from breaking under force.

[0014] In particular, the lower buckle comprises a first lower buckle 31 and a second lower buckle 32, wherein the first lower buckle 31 is provided with a third magnet 33 on one side, while the second lower buckle 32 is provided with a fourth magnet 34 that fits the third magnet 33, wherein the first lower buckle 31 is provided with an arc-shaped recess 35, while the second lower buckle 32 is provided with a fastening block 36 on its base that fits the arc-shaped recess 35. The interaction of the arc-shaped recess 35 and the fastening block 36 allows the first lower buckle 31 and the second lower buckle 32 to be more securely connected to each other, and the first lower buckle 31 and the second lower buckle 32 are not loosened under lateral tensile force.

[0015] The third magnet 33 is located close to the second magnet 26, and the polarity of the top surface of the third magnet 33 is opposite to the polarity of the top surface of the second magnet 26. This configuration can facilitate the engagement of the upper buckle 1 with the lower buckle when the underside of the first magnet 11 of the upper buckle 1 is close to the top surface of the third magnet 33, since the underside of the first magnet 11 and the top surface of the third magnet 33 are repulsive at the same pole, and the repulsive force pushes the first magnet 11 towards the second magnet 26 to engage.

[0016] Furthermore, the first lower buckle 31 and the second lower buckle 32 each comprise a removable upper buckle 41 and a removable lower buckle 42, the lower buckle 42 being provided with an inside-to-outside mounting groove 43 and the upper buckle 41 being provided with a mounting rail 44 that fits into the mounting groove 43. This design further improves the product's safety, as both the upper buckle 41 and the lower buckle 42 can only be released when the upper buckle 1 is released from the lower buckle and the first lower buckle 31 is released from the second lower buckle 32.

[0017] The foregoing detailed description relates to one feasible embodiment of the present invention; however, this embodiment should not limit the scope of protection of the present invention. All equivalent embodiments or modifications that do not deviate from the spirit of the technology of the present invention should be included within the scope of protection of the present invention.
