[0047] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0048] The core of the present utility model is to provide a highly stable magnetic buckle. By arranging mutually attracting magnets in the female buckle and the male buckle, the relative positions of the female buckle and the male buckle can be automatically adjusted, facilitating one-handed blind operation. And when disassembling, under the action of an external force, only the non-insertion end of the clamping component needs to be pressed to achieve quick disassembly, and the use experience is excellent.

[0049] Please refer to Figures 1-8 , a highly stable magnetic snap, including a female buckle and a male buckle 4 that can be inserted into each other. The female buckle includes:

[0050] A sliding channel, which is a long straight channel, and along its length direction inside, a clamping component 2 is slidably installed, and an elastic member 203 that inhibits the insertion of the clamping component 2 is fixedly installed; a plug hole 306 is communicated with the side wall of the sliding channel; a first magnet 5 is fixedly arranged at a position corresponding to the plug hole 306 inside the sliding channel;

[0051] The clamping component 2 is provided with a clamping position portion 2023 at one end inserted into the sliding channel;

[0052] The male buckle 4 includes:

[0053] A clamping post 401 that can be inserted into the plug hole 306, and a wedge surface that cooperates with the clamping position portion 2023 is arranged at the end of the inserted end of the clamping post 401, and an annular card slot 402 is arranged on the circumferential surface of the clamping post 401; when the clamping post 401 is inserted into the plug hole 306, the clamping post 401 can push the clamping component 2 to continue to insert until the clamping position portion 2023 is clamped with the card slot 402;

[0054] A second magnet 6 is fixedly arranged inside the clamping post 401 and can mutually adsorb with the first magnet 5.

[0055] In the application, the sliding channel is a long straight channel. When the clamping component 2 is pressed and moves, it has a good movement track and is not easy to deviate from the established track, and the use experience is better. At the same time, a first magnet 5 is arranged at the position of the plug hole 306 in the sliding channel, and a second magnet 6 is arranged inside the clamping post 401. When it is necessary to combine the male buckle 4 and the female buckle, bring the male buckle 4 close to the female buckle, then the first magnet 5 and the second magnet 6 attract each other, that is, drive the clamping post 401 to approach the plug hole 306, facilitating the quick insertion of the clamping post 401 into the plug hole 306;

[0056] And a mutually cooperating wedge surface is arranged at the contact surface between the inserted end of the clamping post 401 and the clamping position portion 2023. When the clamping post 401 is inserted, the wedge surfaces of the two interact. As the clamping post 401 is inserted, it pushes the clamping component 2 to continuously insert inward until the clamping post 401 reaches the maximum insertion depth. At this time, the card slot 402 of the clamping post 401 is inserted into the plug hole 306, and the clamping component 2 retreats backward under the action of the elastic member 203, so that the clamping position portion 2023 is directly clamped in the card slot 402, that is, the combination of the male buckle 4 and the female buckle is completed. At this time, since the clamping position portion 2023 is clamped in the card slot 402, the clamping post 401 cannot be withdrawn reversely;

[0057] When it is necessary to separate the male buckle 4 from the female buckle, just press the clamping component 2 to make the clamping component 2 continue to insert until the clamping position 2023 disengages from the clamping groove 402. At this time, under the action of external force, the clamping post 401 is pulled out from the insertion hole 306, and the separation of the male buckle 4 and the female buckle is completed. Combining with the actual application scenario, the outer contour of the male buckle 4 is mostly fixed to a larger fabric by sewing or heat pasting, while the female buckle is combined with movable fabrics such as straps. In use, in most cases, the male buckle 4 is in a fixed state, and only the female buckle needs to be held with one hand. When fastening, just guide the female buckle close to the clamping post 401, and under the action of magnetic force, the alignment of the clamping post 401 and the insertion hole 306 is automatically carried out, and press the female buckle to insert the clamping post 401 into the insertion hole 306. When disassembling, hold the female buckle with one hand, press the clamping component 2, and at the same time hold the female buckle away from the male buckle 4. The operation is simple, convenient, can be blindly operated with one hand, and the use experience is good.

[0058] In some embodiments, the sliding channel is composed of the upper cover 1 and the lower cover 3;

[0059] As Figures 3-5 shown, two groups of parallel limiting plates 304 for guiding the sliding of the clamping component 2 are fixedly arranged in the lower cover 3; a pressing strip 102 is fixedly arranged in the upper cover 1 to prevent the insertion end of the clamping component 2 from tilting up;

[0060] As Figure 3 shown, when the clamping component 2 is inserted, it mainly slides between the two groups of limiting plates 304. The limiting plates 304 limit the acting movement of the clamping component 2, and at the same time the pressing strip 102 limits the up and down movement of the clamping component 2, so that the clamping component 2 has a good and smooth movement state after insertion, effectively avoiding movement jamming and improving the use experience.

[0061] Specifically, the two groups of limiting plates 304, the plate surface of the lower cover 3 and the pressing strip 102 of the upper cover 1 together form the sliding channel, and the clamping component 2 acts in the sliding channel;

[0062] At the same time, a spring baffle 303 is also arranged in the lower cover 3, and the elastic member 203 is arranged between the spring baffle 303 and the clamping component 2. When the clamping component 2 is inserted, the elastic member 203 is compressed. When the pressing force on the clamping component 2 is released, the potential energy in the elastic member 203 is released to reset the clamping component 2.

[0063] In some embodiments, as Figure 4 shown, a magnet mounting seat 307 for fixing the first magnet 5 is fixedly arranged in the lower cover 3. The magnet mounting seat 307 is arranged above the insertion hole 306, and the magnet mounting seat 307 is fixed to the lower cover 3 through a vertical bracket 308;

[0064] When the male buckle 4 is separated from the female buckle, the clamping position portion 2023 abuts against the vertical bracket 308 to limit the clamping component 2 from disengaging from the sliding channel.

[0065] As Figure 4 shown, the magnet mounting base 307 has a disc-shaped structure and is suspended and fixed above the insertion hole 306 through the vertical brackets 308 on both sides. The magnet mounting base 307 will not interfere with the movement of the clamping component 2. However, the clamping component 2 preferably has a frame-shaped structure, and the clamping position portion 2023 at its insertion end passes over the magnet mounting base 307. Therefore, when the clamping component 2 is inserted, there will be no interference with the vertical bracket 308. But when the pressing force on the clamping component 2 is released and the elastic member 203 drives the clamping component 2 to reset, the clamping position portion 2023 abuts against the vertical bracket 308, preventing it from continuing to move outwards. At this time, the clamping component 2 reaches a stationary state;

[0066] When designing the position of the vertical bracket 308, it should be ensured that when the clamping post 401 is inserted, it does not affect the clamping of the clamping position portion 2023 and the clamping groove 402. That is, the two vertical brackets 308 should be arranged on both sides of the insertion hole 306, and the connection line of the two vertical brackets 308 is perpendicular to the movement direction of the clamping component 2.

[0067] In some embodiments, as Figure 4 shown, a toggle plate 305 is fixedly arranged inside the lower cover 3. A webbing hole 301 is provided at the root of the toggle plate 305, and the plane where the toggle plate 305 is located is perpendicular to the center line of the insertion hole 306;

[0068] In actual use, most often a webbing is threaded through the webbing hole 301. When separating the female buckle and the male buckle 4, if the webbing presses the toggle plate 305, it is easier to drive the separation of the female buckle and the male buckle 4. That is, when the clamping component 2 is pressed down, the clamping groove 402 is separated from the clamping position portion 2023, and the acting force inside the toggle plate 305 directly drives the female buckle away from the male buckle 4.

[0069] In some embodiments, as Figure 5 shown, a snap mechanism 103 for connecting with the lower cover 3 and a positioning post for inserting and positioning with the lower cover 3 are fixedly arranged inside the upper cover 1; a screw for connecting the upper cover 1 and the lower cover 3 is arranged inside the positioning post;

[0070] The upper cover 1 and the lower cover 3 adopt a split design and are connected through the snap mechanism 103, which is convenient for the assembly of the clamping component 2. At the same time, they are positioned through the positioning posts inside to ensure the accurate assembly position relationship between the two, thereby ensuring the smooth sliding of the clamping component 2.

[0071] In some embodiments, as Figure 1 、 Figure 4 and Figure 5As shown, the outer surfaces of the upper cover 1 and the lower cover 3 are arc-shaped structures, and the arc-shaped channel opening A101 inside the upper cover 1 and the arc-shaped channel opening B302 inside the lower cover 3 form an oval channel opening, and the end face of the non-insertion end of the clamping component 2 is an arc surface;

[0072] The overall appearance of the female buckle has no sharp corners, and the channel opening of the sliding channel is oval, and the exposed clamping component 2 also has no obvious sharp corners. The overall shape is round and will not cause scratches or bruises to the user. It is suitable for use in baby carriers.

[0073] In some embodiments, such as Figure 6 and Figure 7 shown, the clamping component 2 includes a movable frame 202 and a pressing member 201;

[0074] The movable frame 202 is a rectangular closed frame, and the clamping position 2023 is an arc-shaped structure provided in the inner frame of the insertion end of the movable frame 202;

[0075] The pressing member 201 wraps the part of the movable frame 202 exposed outside the sliding channel and is fixedly installed with the buckle part 2021 at the non-insertion end of the movable frame 202;

[0076] Such as Figure 7 shown, the movable frame 202 is a rectangular closed frame, and the clamping position 2023 is an arc-shaped structure. Two sets of clamping positions 2023 can form a closed ring, that is, completely wrap the card slot 402, ensuring the stable insertion of the male buckle 4 and the female buckle;

[0077] And as Figure 7 shown, a wedge surface is provided in the clamping position 2023. When the clamping post 401 is inserted, it can interact with the wedge surface of the clamping position 2023 to drive the movable frame 202 to continue to insert;

[0078] The pressing member 201 can be made of a soft material to improve the feel when pressing.

[0079] In some embodiments, the elastic member 203 is an independent metal spring, one end of which is snapped into the buckle part 2021 and the other end abuts against the spring baffle 303;

[0080] In some other embodiments, the elastic member 203 is integrally injection-molded with the movable frame 202, and the free end is fixedly abutted against the limiting component in the sliding channel.

[0081] In some embodiments, such as Figure 3 and Figure 6 shown, there are two sets of clamping components 2, which are inserted from both ends of the sliding channel respectively. The arc-shaped structures of the two sets of clamping positions 2023 can enclose a closed ring to clamp the card slot 402;

[0082] In some embodiments, a single set of clamping components 2 is used for clamping the clamping post 401. During the clamping process, only partial contact fixation on one side inside the clamping groove 402 can be achieved, and there is a possibility that the clamping post 401 may fall off. Therefore, in some embodiments, two sets of clamping components 2 that move relative to each other are used to clamp and fix the clamping groove 402 from both ends respectively, so as to ensure that the clamping groove 402 can be fully fixed and prevent the male buckle 4 from slipping off the female buckle.

[0083] In some embodiments, as Figure 6 shown, on both sides of the movable frame 202, there are side frames 2022 that slide with the side walls of the sliding channels, and the clamping positions 2023 are fixedly connected to the side frames 2022;

[0084] The clamping positions 2023 of the two sets of movable frames 202 are in the same horizontal plane;

[0085] When designing the two sets of movable frames 202, it is necessary to ensure that the side frames 2022 of the two sets of movable frames 202 can both contact the limiting plate 304. Therefore, when designing the side frames 2022, they can be designed in a stepped shape, that is, the side frames 2022 of the two sets of movable frames 202 are arranged staggeredly, and the clamping positions 2023 of the two sets of movable frames 202 are coplanar and can be combined with the clamping grooves 402 at the same height inside the clamping post 401;

[0086] In some embodiments, the clamping positions 2023 of the two sets of movable frames 202 are not coplanar, and two sets of clamping grooves 402 are correspondingly arranged inside the clamping post 401. This design also falls within the protection scope of this application.

[0087] In some embodiments, as Figure 8 shown, the male buckle 4 further includes a base 404. The clamping post 401 is vertically connected to the base 404. On the surface of the base 404, there is an installation hole communicating with the inner cavity of the clamping post 401, and the second magnet 6 is fixedly installed in the installation hole through a magnet fixing member 403;

[0088] During use, the outer contour position of the base 404 is mostly combined with the fabric by sewing or heat pasting, etc., and its bottom surface is covered by the fabric; before the base 404 is combined with the fabric, the second magnet 6 and the magnet fixing member 403 should be installed into the inner cavity of the clamping post 401 to ensure that the second magnet 6 can attract the first magnet 5.

[0089] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts between the various embodiments, reference can be made to each other.

[0090] The above has introduced in detail the high-stability magnetic snap provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
