Technical Field

[0001] The utility model relates to the technical field of buckles, in particular to a magnetic button. Background Art

[0002] Buckles, as a widely used connection device in daily life, have become an indispensable part of people's lives. They exist on various objects around us, such as bags, clothing, safety gear, etc., and play the role of connection, fixation and beautification. The design and types of buckles are becoming more and more diverse to meet the needs and functions of different objects.

[0003] As a common form, magnetic fasteners are convenient, beautiful and practical, and have been widely welcomed. Among them, magnetic buttons, as a magnetic connection device, are widely used in clothing, decorations, bags and other objects. They firmly connect the two parts together through magnetism, and open and close operations are convenient and quick. However, the size of the magnetic force directly affects the performance of the fastener. Too large or too small will cause a series of problems. In recent years, people have been constantly exploring innovations and improving the design and performance of fasteners to meet people's needs for functionality, aesthetics and convenience. By continuously optimizing the design, magnetic force adjustment and material selection of magnetic buttons, their performance can be improved, so that they can better serve people's lives and bring people a more convenient and comfortable experience.

[0004] CN88201461U discloses a magnetic iron button, which is composed of a suction cup, a magnetic steel and a bent foot. This iron button has two parts, a molecular button and a mother button, and is widely used in leather products. The center of the surface of the mother button magnetic steel of this magnetic button has a notch, and the center of the child button suction cup has a convex surface. When locked, the convex surface falls into the groove, so that the child button and the mother button are closed and overlapped. The metal of the magnetic button can be plated with imitation gold, bronze and other surface treatments and can also be used as a decoration for leather products.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 5 A magnetic button comprises a first fastener 1 and a second fastener 2, wherein a magnetic block 4 is arranged inside the first fastener 1, and the first fastener 1 and the second fastener 2 are respectively provided with a clamping portion and a limiting portion d; the first fastener 1 and the second fastener 2 are fitted together through the magnetic block 4, and can be clamped together through the clamping portion and the limiting portion d; a gap is formed between the clamping portion and the limiting portion d; the first fastener 1 and the second fastener 2 can slide in the gap and lock each other.

[0029] In this embodiment, the first fastener 1 has a cavity a inside and the cavity a is open to the outside through a hole 3. The first fastener 1 is provided with a clamping portion at the hole 3; the clamping portion comprises a first protrusion b and a second protrusion c extending from the hole 3 into the cavity a; the extension length of the first protrusion b is less than the extension length of the second protrusion c; a magnetic block 4 is provided in the cavity a;

[0030] When the second fastener 2 enters the cavity a, under the action of external force, the limiting portion d is offset toward the first protrusion b and is clamped;

[0031] When the second fastener 2 withdraws from the cavity a, under the action of external force, the limiting portion d is offset toward the second protrusion c and is released.

[0032] The structure of this embodiment is novel in design. The cavity a of the first fastener 1 can accommodate the limiting portion d of the second fastener 2 and, under the action of force, the limiting portion d of the second fastener 2 is offset toward the first protrusion b and clamped. Figure 2 Compared with the traditional magnetic button which is fixed entirely by magnetic strength, the above structure can achieve fixation through a smaller magnetic strength, making up for the insufficient magnetic force of the magnetic button; in addition, the structure of this embodiment is simple, the design is user-friendly, and the operation of engagement and separation is quick and convenient.

[0033] In this embodiment, specifically, the first fastener 1 includes a shell 11 and a closing plate 12 ; the shell 11 and the closing plate 12 are connected to form the cavity a; and the hole 3 is provided on the shell 11 .

[0034] Under the above design, the shell 11 and the closing plate 12 are closed to form a cylindrical first fastener 1, and the hole 3 is arranged on its axis and is a circular hole 3, so the locking portion is located on its axis. In actual application, the first protrusion b and the second protrusion c are arranged with the hole 3. In the embodiment, the first protrusion b and the second protrusion c respectively occupy half of the hole 3. Of course, in fact, as long as the second protrusion c does not exceed half of the arc, it is reasonable. This embodiment only provides a better solution.

[0035] As a preferred embodiment of the present invention, the first fastener 1 further includes a top block 13 ; the top block 13 is connected to the closing plate 12 ; one end of the top block 13 extends into the cavity a and is used to press against the second fastener 2 .

[0036] Under the above-mentioned preference, the top block 13 serves to limit the entry depth of the first fastener 1. In practical applications, the top block 13 should be designed based on not blocking the first fastener 1 from entering the first protrusion b.

[0037] In this embodiment, in order to make the magnetic button suitable for the requirements of fixing bags, clothes, etc., the first fastener 1 also includes a first mounting foot 14 and a first base plate 15; the first base plate 15 is provided with a through groove that can be passed by the first mounting foot 14; the other end of the top block 13 extends outward and the first mounting foot 14 and the first base plate 15 are connected thereto.

[0038] Matching with the above-mentioned top block 13 , the second fastener 2 includes a limit block 21 and a clamping plate 22 ; the limit block 21 is connected to the clamping plate 22 ; and one end of the limit block 21 is provided with the limit portion d.

When separation is required, only a slight force is needed to make the card plate 22 and the shell 11 form a certain angle, and the limit portion d can be quickly detached. Figure 3 .

[0040] Similar to the above-mentioned first fastener 1, in this embodiment, in order to make the magnetic button suitable for the requirements of fixing purses, clothes, etc., the second fastener 2 also includes a second mounting foot 23 and a second base plate 24; the second base plate 24 is provided with a through groove that can be passed by the second mounting foot 23; the other end of the limit block 21 extends outward and the second mounting foot 23 and the second base plate 24 are connected thereto.

[0041] Further preferably, in order to further stably engage, through holes are provided on the axes of the top block 13 and the limit block 21. Figure 4Of course, even if there is no through hole on the axis of the top block 13 and the limit block 21, the present solution can still be implemented normally, but the through hole can increase the magnetic strength by about 10% during engagement.

[0045] In this embodiment, specifically, the first fastener 1 has a cavity a inside and the cavity a is open to the outside through a hole 3. The first fastener 1 includes a shell 11 and a closing plate 12; the shell 11 and the closing plate 12 are connected to form the cavity a; the hole 3 is set on the shell 11.

[0046] As a preferred embodiment of the present invention, the first fastener 1 further includes a top block 13 ; the top block 13 is connected to the closing plate 12 ; one end of the top block 13 extends into the cavity a and is used to press against the second fastener 2 .

[0047] Matching with the above-mentioned top block 13 , the second fastener 2 includes a limit block 21 and a clamping plate 22 ; the limit block 21 is connected to the clamping plate 22 ; and one end of the limit block 21 is provided with the limit portion d.
