Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present application recites a magnetic clasp comprising two first clasp body 20 and second clasp body 10 magnetically coupled.

As shown in fig. 1, the first buckle 20 is a hollow ring body, two through holes are formed in the ring body, the through holes are opposite to each other and penetrate through the wall of the ring body, a first magnetic element 210 capable of moving relative to the ring body is arranged in each through hole, and the first magnetic element 210 moves relative to the ring body under the action of external force. In order to prevent the first magnetic element 210 from falling off from the through hole, a pin hole penetrating through the through hole is further formed in the ring body, a pin 30 is arranged in the pin hole and penetrates through the first magnetic element 210, and the first magnetic element 210 is limited on the first buckle body 20.

As shown in fig. 3, the first magnetic element 210 is provided with a movable hole, and the pin 30 passes through the movable hole, so that the first magnetic element 210 is restricted by the pin 30 during the moving process, and the first magnetic element 210 can move left and right in the through hole without being separated from the through hole.

Referring to fig. 2, the second button body 10 is substantially in a cap shape, and includes a proximal end and a distal end, the second magnetic element 110 is disposed on the proximal end, the second magnetic element 110 protrudes toward the first button body 20, and the second magnetic element 110 may protrude into the hollow of the first button body 20 to be opposite to the first magnetic element 210. When the second magnetic element 110 is located between the two first magnetic elements 210, due to the relationship between the relative magnetic poles of the first magnetic element 210 and the second magnetic element 110, the two first magnetic elements 210 are respectively close to or far away from the second magnetic element 110, so as to realize the locking or unlocking function between the first buckle body 20 and the second buckle body 10.

In one embodiment, the two first magnetic elements 210 have the same poles opposite to each other, and the first magnetic elements 210 have the same poles as the second magnetic elements 110, so that when the second magnetic elements 110 extend into the hollow position and face the first magnetic elements 210, the first magnetic elements 210 are influenced by the repulsive force of the same poles to move away from the second magnetic elements 210 and move toward the distal end of the second button body 20.

In another embodiment, the relative magnetic poles of the first magnetic element 210 and the second magnetic element 110 are opposite, when the second magnetic element 110 extends into the hollow position and is opposite to the first magnetic element 210, the first magnetic element 210 is influenced by the opposite-pole attraction force to approach the second magnetic element 210 until the first magnetic element 210 and the second magnetic element 110 are attached together by attraction, and the first buckle body 20 and the second buckle body 20 are connected together by the attraction force.

It can be known that the first button body 20 and the second button body 10 can rotate relatively, during the rotation, the first magnetic element 210 can be staggered with the second magnetic element 110, since the magnetic poles of the magnetic elements are no longer opposite, so that the first button body 20 can be separated from the second button body 10.

As shown in fig. 1-4, the second buckle body 10 is further provided with two magnets 40 respectively opposite to the first magnetic element 210 in addition to the second magnetic element 110, wherein the magnets 40 and the first magnetic element 210 have the same pole pair. When the first buckle body 20 and the second buckle body 10 rotate relatively, the first magnetic element 210 is moved towards the second magnetic element 110, and the first magnetic element 210 is moved towards the second magnetic element 110 by the repulsion force of the same polarity of the magnet 40, so as to enhance the connection strength between the two buckle bodies. When the magnetic poles of the first magnetic element 210 and the second magnetic element 110 are staggered, the overall external force applied to the first magnetic element 210 is weakened, so that the first button body 20 and the second button body 10 are separated.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
