Description

Technical Field

[0001] This utility model relates to metal fasteners, and more particularly to a thin magnetic fastener assembly with an attraction guide structure. Background Technology

[0002] Patent document CN114183447A discloses a magnetic snap fastener, which includes a first connecting part and a second connecting part. The first connecting part is provided with a first magnet and a protrusion, the side wall of which has a slot. The second connecting part is provided with a second magnet and a groove, the inner wall of which has an elastic buckle. The first and second magnets have multiple corresponding magnetic poles. When the magnetic snap fastener is in the attracted state, the protrusion is inserted into the groove, the opposite magnetic poles of the first and second magnets face each other and attract each other, and the elastic buckle is accommodated in the slot. The magnetic snap fastener securely fixes the product through the combined action of magnetic force and the snap fastener. Rotating the snap fastener unlocks the structure, and the magnetic repulsion causes the snap fastener to spring open. The magnetic snap fastener achieves the required fixation strength while keeping the magnet's volume and net weight smaller. However, this magnetic snap fastener has a relatively complex magnet installation structure, resulting in a large axial dimension with no room for reduction. It also requires accurate alignment during fastening, leading to poor ease of use and incompatibility with thin fabrics. Therefore, it is necessary to optimize the structure of this magnetic snap fastener to overcome the above-mentioned defects. Utility Model Content

[0007] The male snap fastener can be installed on the fabric through a male snap fastener riveting structure. It is adapted to the shape of the female snap fastener and can be fastened to the female snap fastener. The female snap fastener supports and positions the male snap fastener.

[0008] in:

[0009] The female part of the suction-and-fasten is provided with a guide ring. The guide ring is located at the front edge of the female part of the suction-and-fasten, extends circumferentially along the female part of the suction-and-fasten, and protrudes axially towards the front of the female part of the suction-and-fasten, forming a load-bearing and positioning space between the inner wall of the guide ring and the front of the female part of the suction-and-fasten.

[0010] The male fastener has a guide groove located at the front edge of the male fastener, extending circumferentially and recessed axially into the male fastener. The guide groove is adapted to the shape of the guide ring. When the male fastener is fastened onto the female fastener, the guide ring is placed in the guide groove, and the guide groove and guide ring guide the fastening process.

[0011] In one embodiment of this utility model, the ratio of the diameter to the thickness of the female snap fastener is 8:1 to 10:1, and the ratio of the diameter to the thickness of the male snap fastener is 8:1 to 10:1.

[0012] Specifically, the snap-fit ​​female component includes:

[0013] The mother panel is made of metal sheet by stamping and has a ring structure. Its outer edge is rolled forward along the axial direction of the mother panel to form a guide ring. Its inner edge is rolled backward along the axial direction of the mother panel and then rolled inward along the radial direction of the mother panel to form a mother positioning ring. It can be installed on the fabric through a mother riveting structure that matches the shape of the mother positioning ring.

[0014] The back plate of the mother part is made of metal sheet by stamping and has a ring structure. It is located behind the mother part panel. Its inner edge abuts against the outer wall of the positioning ring of the mother part. The edge of the guide ring is rolled up axially towards the rear of the mother part panel and wrapped around the outer edge of the back plate of the mother part, so that the back plate of the mother part is fixedly connected to the mother part panel.

[0015] The snap-fit ​​female also includes:

[0016] The female magnetic ring is located between the female back plate and the female front plate. The middle part of the female back plate protrudes backward, forming a space for receiving the female magnetic ring between the female front plate and the female back plate. The female magnetic ring is clamped and positioned by the female front plate and the female back plate.

[0017] The fastener male components include:

[0018] The male part panel is made of metal sheet by stamping and has a ring structure. Its outer edge is bent obliquely backward and expands outward along the radial direction of the male part panel to form a guide groove. Its inner edge is rolled backward along the axial direction of the male part panel and then rolled inward along the radial direction of the male part panel to form a male part positioning ring. It can be installed on the fabric by a male part riveting structure that matches the shape of the male part positioning ring.

[0019] The back panel of the component is made of metal sheet by stamping and has a ring structure. It is located behind the front panel of the component. Its inner edge abuts against the positioning ring of the component. The edge of the guide groove is rolled back towards the rear of the front panel of the component and wrapped around the outer edge of the back panel of the component, so that the back panel of the component is fixedly connected to the front panel of the component.

[0020] The snap-fit ​​connector also includes:

[0021] A magnetic ring for a public component is located between the back plate and the front plate of the public component. The back plate protrudes backward from the middle, forming a space for the magnetic ring between the front plate and the back plate. The magnetic ring is clamped and positioned by the front plate and the back plate.

[0022] The advantages of this utility model are:

[0023] The guide ring of the female component and the guide groove of the male component form a nested fit, which can physically guide the alignment before the magnetic force is applied, avoiding the misalignment and friction problems of traditional magnetic snaps. It can achieve blind operation and quick snapping, which is especially suitable for one-handed operation. After snapping, the inner wall of the guide ring and the bearing space formed by the front of the female component tightly wrap the male component to prevent lateral displacement or rotational loosening. The positioning rings of the female and male components hide the rivet points through the folding structure, which is simple in appearance and avoids scratching the skin or clothing. Through the stamped metal sheet and compact magnetic ring layout, the thickness is significantly lower than that of traditional magnetic snaps, which is suitable for thin fabrics without appearing bulky.
