Description

Technical Field

[0001] The utility model relates to the field of clothing fasteners, in particular to a webbing fastener that is inserted magnetically from the side. Background Art

[0002] Lightweighting a buckle offers advantages such as cost reduction for products, but this reduction can also impact product reliability. Lightweighting can be achieved through improvements in both material and structure. Reducing surface area structurally is one approach to lightweighting. For example, patent application 200980158242.0 discloses a side-release buckle. This invention utilizes a notch formed in the main body to reduce the surface area of ​​the socket body, effectively meeting the lightweighting requirement. Similarly, this invention maximizes the notch area within the non-exposed leg and connector sections, further achieving lightweighting. Simplified buckles often present issues that impact product reliability. These include: Overall buckle strength is insufficient after simplification, encompassing not only the male buckle or female buckle, but also the tensile strength of the two when inserted together. The pins, a vulnerable component of the buckle, are further weakened during lightweighting, making them more susceptible to unacceptable deformation. Furthermore, the pins are not guided until they are halfway into the female buckle, making them prone to misalignment. The guide mechanism delays the effective insertion of the guide.

[0003] To this end, the patent application 201210410326.2 discloses a buckle, whose foot uses double spring pieces, and distinguishes between primary and secondary spring pieces, so that the foot is not easy to break when it is forward and backward, and will not bounce around and be damaged after breaking.

[0004] However, the existing buckles and the above-mentioned solutions are mostly straight-plug connections. When the tension of the belt increases, it is still possible that the buckle port will be stretched, and the tension it can withstand is limited. Therefore, it is necessary to set up a side-plug connection method on this basis to offset the tension of the belt. At present, there is no complete solution for side-plug buckles on the market, so the existing buckles still have room for improvement. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0006] A side-insertion magnetic webbing fastener comprises a bottom buckle and a plug buckle; the bottom buckle and the plug buckle are plugged into and assembled with each other to form a square structure; the middle of each of the bottom buckle and the plug buckle is inlaid with a magnetic element, and the two magnetic elements are magnetically connected to each other;

[0007] A first protrusion is formed on the front side of the bottom buckle, and a first special-shaped curved edge is formed at the top edge of the first protrusion. A second protrusion is formed on the back side of the buckle, and a second special-shaped curved edge is formed at the bottom edge of the second protrusion. The second special-shaped curved edge is matched with the first special-shaped curved edge.

[0008] Furthermore: a limiting groove is formed at the edge where the first special-shaped curved edge and the bottom buckle contact each other, and a limiting edge is formed at the edge away from the buckle side of the second special-shaped curved edge, and the clearance fitting side of the limiting edge is inserted into the limiting groove.

[0009] Furthermore: the magnetic element on the bottom buckle and the first protrusion are staggered with each other, and the magnetic element on the plug buckle and the second protrusion are staggered with each other.

[0010] Furthermore: a first recessed groove is formed on the front side of the bottom buckle, and the magnetic part of the bottom buckle is embedded and installed in the first recessed groove. The front side surface of the magnetic part in the bottom buckle and the front side surface of the bottom buckle are arranged flush with each other, and the first special-shaped curved edge is located on the bottom and right sides of the first recessed groove.

[0011] Furthermore: the limiting groove is arranged on a side of the first special-shaped curved edge close to the first concave groove.

[0012] Furthermore: a second recessed groove is formed in the middle of the front side of the buckle, and the magnetic part of the buckle is embedded in the second recessed groove; after the bottom buckle and the buckle are assembled with each other, the two magnetic parts are arranged with the buckle between them, and the two magnetic parts are magnetically connected to each other in a front-to-back manner.

[0013] Furthermore: the front side surface of the magnetic element in the buckle and the front side surface of the buckle are arranged flush with each other.

[0014] Furthermore: a first buckle is formed on the left side of the bottom buckle, and a second buckle is formed on the right side of the insert buckle.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The buckle can be inserted into the bottom buckle by side insertion and fixed by magnetic attraction, which is convenient and quick;

[0017] 2. After plug-in assembly, the second special-shaped curved edge will just rest against the first special-shaped curved edge, achieving a stable side-plug connection that is not prone to loosening.

[0019] 4. It is not a traditional straight-insert buckle, so it can withstand greater pulling force without breaking, and it can also be convenient for practical use through side-insertion magnetic attraction.

[0020] 5. The stability of the side-insertion assembly can be improved by inserting the limiting edge into the limiting groove. After the side insertion is completed, the bottom buckle and the insert buckle can always maintain a flat contact state with each other, so that the insert buckle cannot be opened by flipping, thereby achieving a better and more stable connection effect.

[0034] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] like Figure 1-6 As shown, the utility model is a webbing fastener by side-insertion magnetic attraction, comprising a bottom buckle 1 and a plug buckle 2; the bottom buckle 1 and the plug buckle 2 are plugged and assembled with each other, and the bottom buckle 1 and the plug buckle 2 are assembled to form a square structure. The middle of the bottom buckle 1 and the plug buckle 2 are embedded with a magnetic attraction member 3, and the two magnetic attraction members 3 are magnetically connected to each other;

[0036] The front side of the bottom buckle 1 is formed with a first protrusion 4, and the top edge of the first protrusion 4 is formed with a first special-shaped curved edge 5. The rear side of the insert buckle 2 is formed with a second protrusion 6, and the bottom edge of the second protrusion 6 is formed with a second special-shaped curved edge 7. The second special-shaped curved edge 7 is matched with the first special-shaped curved edge 5.

[0037] The principle is: the buckle 2 can be inserted into the bottom buckle 1 by side insertion and is magnetically fixed by the magnetic attraction part 3. After plugging and assembling, the second special-shaped curved edge 7 will just rest on the first special-shaped curved edge 5, realizing a stable side-insertion connection, which is not easy to loosen by itself. After connecting nylon belts, webbings, and belts to the bottom buckle 1 and the buckle 2, it can be used as a connecting buckle for clothing fastening belts. Since it is not a straight-insert buckle, it can withstand greater tension without breaking, and it can also be convenient for practical use through side-insertion magnetic attraction.

[0038] Furthermore: a limiting groove 8 is formed at the edge position where the first special-shaped curved edge 5 and the bottom buckle 1 contact each other, and a limiting edge 9 is formed at the edge position of the second special-shaped curved edge 7 away from the plug buckle 2, and the limiting edge 9 is inserted into the limiting groove 8 with a clearance fit; the stability of the side insertion assembly can be improved by inserting the limiting edge 9 into the limiting groove 8. After the side insertion is completed, the bottom buckle 1 and the plug buckle 2 can always maintain a state of plane abutting each other, so that the plug buckle 2 cannot be opened by flipping, thereby achieving a more stable connection effect.

[0039] Furthermore: the magnetic part 3 on the bottom buckle 1 and the first protrusion 4 are staggered with each other, and the magnetic part 3 on the plug buckle 2 and the second protrusion 6 are staggered with each other; so that the magnetic part 3 can not affect the bottom buckle 1 and the plug buckle 2.

[0040] Furthermore: a first recessed groove 10 is formed on the front side of the bottom buckle 1, and the magnetic component 3 of the bottom buckle 1 is embedded in the first recessed groove 10. The front side surface of the magnetic component 3 in the bottom buckle 1 and the front side surface of the bottom buckle 1 are arranged flush with each other, and the first special-shaped curved edge 5 is located on the bottom and right side of the first recessed groove 10; the limiting groove 8 is arranged on the side of the first special-shaped curved edge 5 close to the first recessed groove 10; it can effectively fix the magnetic component 3 of the bottom buckle 1, and after the side insertion is completed, the magnetic component 3 can be blocked by the first special-shaped curved edge 5, thereby ensuring the stability of the snap connection.

[0041] Furthermore: a second recessed groove 11 is formed in the middle of the front side of the buckle 2, and the magnetic part 3 of the buckle 2 is embedded in the second recessed groove 11; after the bottom buckle 1 and the buckle 2 are assembled with each other, the two magnetic parts 3 are arranged with the buckle 2 between them, and the two magnetic parts 3 are magnetically connected to each other in a front-to-back manner; the buckle 2 is used to separate the two magnetic parts 3 to prevent the magnetic parts 3 from being too attracted and falling out of the first recessed groove 10 or the second recessed groove 11 when inserted from the side, thereby ensuring the stable installation of the magnetic parts 3.

[0042] Furthermore, the front surface of the magnetic element 3 in the buckle 2 and the front surface of the buckle 2 are flush with each other, so that the magnetic element 3 does not protrude, ensuring the neatness of the overall buckle and improving the aesthetics.

[0043] Furthermore: a first buckle 12 is formed on the left side of the bottom buckle 1, and a second buckle 13 is formed on the right side of the insert buckle 2; the first buckle 12 and the second buckle 13 can be used to install and connect nylon belts, webbings, and belts, making it convenient to use it as a connecting buckle for clothing fastening belts.

[0044] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of protection of the technical solution of the utility model.
