Technical Field

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

[0002] Buckles, as locking devices, are widely used in luggage, clothing, outdoor sports equipment, and other fields. Buckles typically consist of two parts that are installed on two separate components to connect or disconnect them. Currently, there are many types of buckles, and magnetic buckles have become a common type of buckle due to their easy connection and disassembly.

[0003] Existing magnetic fasteners often achieve connection through the magnetic force generated between magnets or magnets and metal. This connection method is not strong and can be easily separated by external forces, especially in more professional application scenarios such as outdoor applications. Utility Model Content

[0004] The main purpose of the utility model is to provide a magnetic fastener that can effectively solve the problems in the background technology.

[0031] Example

[0032] Reference Figure 1-4 , a magnetic buckle, comprising a base 1, a top cover 2 and a buckle 3;

[0033] The base 1 has a slot 11 on one side of its upper end surface, with a lower magnet 111 embedded in the bottom of the slot 11. The base 1 has a buckle seat 12 and an arched spring piece 13 on the other side of its upper end surface. The arched spring piece 13 is located between the buckle seat 12 and the slot 11. The upper end surface of the buckle seat 12 is a guiding inclined surface 121 facing the arched spring piece 13.

[0034] The lower end surface of the top cover 2 has an insert block 21 on one side, and an upper magnet 211 is embedded at the bottom of the insert block 21. The insert block 21 is adapted to the slot 11, and the side of the top cover 2 has a mounting groove 22;

[0035] The buckle 3 is rotatably mounted in the mounting groove 22 . The bottom of the buckle 3 has a buckle hook 31 . The buckle hook 31 is used for buckling with the buckle seat 12 .

[0036] When the buckle is fastened, the top cover 2 is brought close to the base 1, and the insert block 21 is inserted into the slot 11. Under the adsorption action of the upper magnet 211 and the lower magnet 111, the top cover 2 and the base 1 are magnetically connected. The cooperation of the insert block 21 and the slot 11 can achieve precise positioning of the top cover 2 and the base 1.

[0037] As the top cover 2 and the base 1 approach each other, the snap hook 31 of the buckle 3 moves along the guide slope 121 and squeezes the arched spring piece 13, causing the arched spring piece 13 to be compressed and deformed. When the upper magnet 211 and the lower magnet 111 contact each other, the snap hook 31 is smoothly inserted into the snap seat 12, the arched spring piece 13 restores its shape, and limits the snap hook 31, so that the snap hook 31 and the snap seat 12 cannot be easily separated, and a stable snap connection is achieved between the top cover 2 and the base 1.

[0038] When the buckle needs to be disassembled, it is only necessary to pry the buckle 3, and the buckle hook 31 squeezes the arched spring piece 13, the arched spring piece 13 is deformed under pressure, and the buckle hook 31 is separated from the buckle seat 12. At this time, the top cover 2 and the base 1 can be separated to complete the disassembly.

[0039] The present invention can ensure the connection strength of the buckle through the magnetic connection between the upper magnet 211 and the lower magnet 111 and the snap connection between the snap hook 31 and the snap seat 12. Through the precise positioning of the insert block 21 and the slot 11 and the setting of the snap 3, the buckle can be operated with one hand whether it is fastened or disassembled, and the operation is simple and convenient.

[0040] In a specific embodiment, there are rotation grooves 221 on both sides of the installation groove 22, and there are rotation protrusions 32 on both sides of the buckle 3. The rotation protrusions 32 are clamped in the rotation grooves 221, so that the buckle 3 can rotate around the two rotation grooves 221.

[0041] In a specific embodiment, the installation slot 22 is an open slot, and the provision of the open slot can facilitate the operation of the buckle 3 .

[0042] In one specific embodiment, the mounting groove 22 further comprises track grooves 222 on both sides. One end of each track groove 222 communicates with the rotation groove 221, and the other end extends to the side edge of the top cover 2. The depth of each track groove 222 is less than the depth of the rotation groove 221. To install the snap-on buckle 3, the two rotation protrusions 32 can be first inserted into the two track grooves 222 from the side edge of the top cover 2. The snap-on buckle 3 can then be pushed inward along the track grooves 222 until the two rotation protrusions 32 fall into the rotation grooves 221. Because the depth of the track grooves 222 is less than the depth of the rotation groove 221, the rotation protrusions 32 will not easily disengage from the rotation grooves 221 after they fall into the rotation grooves 221, ensuring the normal rotation of the snap-on buckle 3. To remove the snap-on buckle 3, the rotation protrusions 32 can first be moved into the track grooves 222, allowing the snap-on buckle 3 to be removed along the track grooves 222. The provision of the track grooves 222 facilitates the installation and removal of the snap-on buckle 3.

[0043] In a specific embodiment, the track groove 222 is V-shaped.

[0044] In a specific embodiment, both the base 1 and the top cover 2 are provided with tether holes for easy connection with straps or ties.

[0045] In a specific embodiment, the base 1, top cover 2 and buckle 3 are all integrally injection-molded from POM material, saving overall assembly costs. The use of POM plastic material can ensure the overall lightness of the buckle. At the same time, since the POM plastic material has good toughness, it can also ensure the overall strength of the buckle.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
