Description

Technical Field

[0001] The utility model relates to the technical field of safety buckles, and more specifically, to a safety buckle. The utility model also relates to a piece of clothing including the above safety buckle. Background Art

[0002] The anti-side-pull magnet safety buckle often appears in our daily life in various forms, such as on clothes and document bags, and its main function is to seal and fix; the anti-side-pull magnet safety buckle uses the principle of magnetic attraction when buckling, and the protruding part of the male buckle extends into the through hole of the female buckle to play a role in preventing side pull.

[0003] However, in actual use, in order to ensure that the male buckle does not separate from the female buckle by itself during use, an annular groove is provided at the root of the column head to limit the column head from disengaging from the lock hole of the female buckle. When the male buckle and the female buckle bear a large radial force, due to the existence of the annular groove, the column head cannot disengage from the lock hole in time, which causes the column head or the lock hole to deform, resulting in damage to the safety buckle and inability to be used again; if the column head of the male buckle is removed, when the male buckle and the female buckle bear a small radial force, the two will separate, losing the original function of the safety buckle.

[0004] In summary, how to provide a safety buckle and a piece of clothing that can solve the problem of the safety buckle failing or being damaged under radial force is an urgent problem for those skilled in the art at present. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a safety buckle, which adopts a double-layer column head to increase its rigidity and avoid deformation under force. At the same time, the included angle between the outer wall of the column head and the inner wall of the lock hole is an acute angle. When the male buckle assembly and the female buckle assembly bear a radial force, a force that causes them to separate from each other will be generated between the column head and the lock hole. When the radial force exceeds the set value, this force can drive the column head to disengage from the lock hole, thereby avoiding damage to the safety buckle caused by deformation of the column head or the lock hole.

[0006] Another purpose of the utility model is to provide a piece of clothing including the above safety buckle, which has the same technical features and can achieve the same effect.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] The core of this utility model is to provide a safety buckle, which adopts a double-layer column head to increase its rigidity and prevent it from being deformed by force. At the same time, the angle between the outer wall of the column head and the inner wall of the locking hole is an acute angle. When the male buckle component and the female buckle component are subjected to radial force, a mutual separation force will be generated between the column head and the locking hole. When the radial force exceeds the set value, the force can drive the column head to separate from the locking hole, thereby avoiding damage to the safety buckle caused by deformation of the column head or the locking hole.

[0040] Another core of the present invention is to provide a garment comprising the above-mentioned safety buckle, which has the same technical features and can achieve the same technical effects.

[0041] Please refer to Figures 1 - 8 , a safety buckle, comprising:

[0042] The female buckle assembly 1 includes a locking hole 111;

[0043] The male buckle assembly 2 includes a stud 231 that can be inserted into the locking hole 111. The stud 231 is a double-layer stamped structure, and the angle between the outer wall of the stud 231 and the inner wall surface of the locking hole 111 at the contact point is acute. A first magnet 12 and a second magnet 22 that attract each other are provided between the female buckle assembly 1 and the male buckle assembly 2.

[0044] When the column head 231 is inserted into the locking hole 111, the first magnet 12 and the second magnet 22 attract each other by magnetic force, fixing the female buckle assembly 1 and the male buckle assembly 2 to each other, and the column head 231 and the locking hole 111 limit each other, restricting the relative radial movement of the female buckle assembly 1 and the male buckle assembly 2;

[0045] When the male buckle assembly 2 and the female buckle assembly 1 are subjected to a radial force, the male buckle assembly 2 and the female buckle assembly 1 undergo relative radial displacement. Among them, the column head 231 moves synchronously with the male buckle assembly 2. The outer wall of the column head 231 abuts against the hole wall of the locking hole 111. The angle between the outer wall of the column head 231 and the inner wall of the locking hole 111 at the abutting position is an acute angle α. When the radial force continues to increase, it will cause the column head 231 to generate a flipping force, guiding the column head 231 to flip outward with the abutting position as the center. When the flipping force reaches a certain value, the column head 231 flips, so that the column head 231 disengages from the locking hole 111, that is, the male buckle assembly 2 is separated from the female buckle assembly 1, avoiding damage to the column head 231 or the locking hole 111;

[0046] As Figure 7 shown, the column head 231 in the male buckle assembly 2 adopts a double-layer stamping structure, thereby enhancing its rigidity. When subjected to a radial force, the probability of its deformation decreases, and it is formed by stamping, with a hollow structure inside, which helps to reduce the product weight and improve the use experience.

[0047] In some embodiments, the outer wall of the column head 231 is a conical surface, and the outer diameter of the end of the column head 231 is larger than the outer diameter of the root;

[0048] As Figure 7 shown, through the structural design of the outer wall of the column head 231, it is made into a conical structure, and the outer diameter of the upper end is larger than the outer diameter of the lower end. When the female buckle assembly 1 and the male buckle assembly 2 are combined and both are subjected to a radial force and undergo radial displacement until the outer wall of the column head 231 abuts against the hole wall of the locking hole 111, during the process, it is not affected by the change in the thickness of the object clamped between the female buckle assembly 1 and the male buckle assembly 2, and the angle between the outer wall of the column head 231 and the inner wall of the locking hole 111 is always an acute angle.

[0049] In some embodiments, a raised arc ring is provided at the end of the outer wall of the column head 231, and the angle between the root of the arc ring and the outer wall surface of the column head 231 is an obtuse angle;

[0050] As Figure 8As shown, by setting a raised arc-shaped ring, the force required for the male buckle component 2 to disengage from the female buckle component 1 can be further increased. Meanwhile, through the design of the angle between the root of the arc-shaped ring and the outer wall surface of the column head 231, when the outer wall of the column head 231 abuts against the inner wall of the locking hole 111, the angle between the outer wall of the arc-shaped ring and the inner wall of the locking hole is an acute angle. However, during use, it should be ensured that the abutting position between the outer wall of the column head 231 and the inner wall of the locking hole 111 is below the outer wall of the arc-shaped ring and does not exceed the part of the arc-shaped ring.

[0051] In some embodiments, the arc-shaped ring and the column head 231 are integrally formed by stamping, and the inside of the column head 231 is a hollow structure. By the integrally formed arc-shaped ring, that is, an additional bend is added at the end of the column head 231, the stiffness of the end of the column head 231 is further improved, which helps to maintain the roundness of the end of the column head 231 after long-term use, and thus ensures the smoothness of the operation of the safety buckle.

[0052] In some embodiments, the center position of the end of the column head 231 is recessed downward to avoid interference with the convex part in the inner cavity of the female buckle component 1;

[0053] As Figure 7 shown, during the assembly process of the female buckle component 1, convex parts will appear inside. By setting a recessed area at the center of the column head 231, interference between the end of the column head 231 and the convex parts inside the female buckle component 1 can be avoided, and the end of the column head 231 can be prevented from being scratched.

[0054] In some embodiments, the male buckle component 2 further includes a second locking part 21. The second magnet 22 is in a ring structure and is concentrically arranged with the second locking part 21 and the column head 231. The second locking part 21 wraps the second magnet 22, and the column head 231 is fixedly connected to the second locking part 21 relatively;

[0055] As Figure 4 and Figure 6 shown, by setting the second locking part 21 to wrap the second magnet 22, the second magnet 22 can be protected, the damage of the second magnet 22 can be avoided, and the durability of the safety buckle can be improved.

[0056] In some embodiments, the male buckle component 2 further includes a second fixing part 23 and a second binding part 24. The second fixing part 23 is fixedly connected to the second locking part 21;

[0057] The column head 231 is a ring-shaped protrusion that bends upward at the middle position of the second fixing part 23, and a through hole is provided in the middle of the ring-shaped protrusion. The second insertion sleeve 241 of the second binding part 24 passes through the through hole, and a flanging facing outward is provided at the end, and the flanging fits with the inner wall of the through hole;

[0058] Through the interaction between the second fixing part 23 and the second binding part 24, the second locking part 21 is fixed to the connected part;

[0059] Meanwhile, the column head 231 is formed by stamping with the second fixing member 23, which reduces the production cost and improves the production efficiency.

[0060] In some embodiments, the female buckle assembly 1 further includes a first locking portion 11. The first magnet 12 is an annular magnet and is concentrically arranged with the first locking portion 11. The first locking portion 11 wraps the first magnet 12.

[0061] The locking hole 111 is a through hole at the center of the first locking portion 11, and the inner diameter of the first magnet 12 is larger than the inner diameter of the through hole. When the column head 231 is inserted, the outer wall of the column head 231 will not contact the inner wall of the first magnet 12.

[0062] By wrapping the first magnet 12 with the first locking portion 11, the protection of the first magnet 12 is improved, the damage of the first magnet 12 is avoided, and the durability of the safety buckle is enhanced.

[0063] At the same time, the inner diameter of the first magnet 12 and the aperture of the locking hole 111 are restricted, so that after the column head 231 is inserted, the first magnet 12 will not be squeezed, so that the first magnet 12 will not be crushed by the column head 231, and the durability of the safety buckle can also be enhanced.

[0064] In some embodiments, the female buckle assembly 1 further includes a first fixing member 13 and a first binding member 14. The first fixing member 13 is fixedly connected to the first locking portion 11, and a through hole is provided at the center of the first fixing member 13. The first insertion sleeve 141 of the first binding member 14 penetrates through the through hole, and the end is flanged, and the flange fits with the inner wall of the through hole.

[0065] Through the action of the first fixing member 13 and the first binding member 14, it is convenient to combine the female buckle assembly 1 with the to-be-connected member, and the use convenience of the safety buckle is improved.

[0066] In addition to the safety buckles disclosed in the above various embodiments, the present invention also provides a piece of clothing including the above safety buckle. For the structures of other parts of the clothing, please refer to the prior art and will not be elaborated herein.
