Description

Technical Field

[0001] The utility model relates to the field of fasteners, and particularly to a magnetic buckle. Background Art

[0002] In the fields of luggage and clothing, in order to meet the need for quick matching, buckles are generally used as connecting accessories. A buckle is generally composed of two parts with mutually cooperating shapes. These structures can ensure that it does not open under a certain load. In order to meet the convenient and fast use of buckles by consumers to complete the opening and closing actions, magnetic buckles are added to traditional buckles. They are commonly used in luggage, clothing, shoes, helmets and other work that requires buckles to be opened and closed.

[0003] In order to solve the problem that the magnetic buckle is prone to position deviation during impact, resulting in detachment between the male buckle and the female buckle, and to improve the use safety and the structural connection stability, our company applied for a patent with the patent number CN218605358U in 2022, namely "An easily detachable buckle", which includes a first buckle and a second buckle that are mutually engaged, and corresponding magnetic parts are respectively arranged on the first buckle and the second buckle. At least one first block and a first slot are oppositely arranged on the engaging surface of the first fastener along the engaging direction, and a second slot and a second block corresponding to the first block and the first slot are arranged on the second fastener. Tilted guiding blocks are arranged on both sides of the second block, and an included angle is arranged between the tilted guiding blocks and the engaging surface of the first fastener. However, in actual use, users reported the following problems: when this structure falls, one of the male buckle or the female buckle structures will contact the ground first, resulting in the mating surface between the male buckle and the female buckle being misaligned and separated, and finally it is still easy to have the problem of misalignment and detachment between the male buckle and the female buckle, and there is still an unstable installation situation.

[0004] In order to solve the above-mentioned existing technical problems, a new type of magnetic buckle with a limiting sliding part arranged on the outer layer interface of the oblique intersection of the male buckle and the female buckle is proposed in this solution. Content of the Utility Model

[0005] The main purpose of the utility model is to overcome the deficiencies of the prior art and provide a magnetic buckle.

[0006] The utility model is implemented by adopting the following technical scheme: a magnetic buckle, whose structure includes a first fastener and a second fastener that are mutually engaged, and relatively cooperating magnetic parts are respectively embedded on the first fastener and the second fastener. The second fastener is installed above the first fastener during assembly, and a limiting iron sheet is hinged and covered above the second fastener. Anti-sliding sheets are arranged on the two outer sides of the limiting iron sheet facing outwards, and the anti-sliding sheets abut against the edge of the outer shell of the first fastener when the second fastener moves towards the first fastener to the extreme position.

[0007] Further, at least one first locking block and a first locking groove are oppositely arranged on the engaging surface of the first fastener along the engaging direction. Second locking grooves and second locking blocks corresponding to the first locking block and the first locking groove are arranged on the second fastener. Inclined guiding blocks are arranged on both sides of the second locking block, and an included angle is formed between the inclined guiding block and the engaging surface of the first fastener. When the first fastener and the second fastener are attracted, the first locking block is engaged with the second locking groove, and the first locking groove is separated from the second fastener.

[0008] Limiting posts are symmetrically arranged on both sides of the first fastener, and limiting grooves corresponding to the limiting posts are arranged on the side wall of the second fastener. The first locking block abuts against the second locking groove.

[0009] The limiting post is provided with an inclined surface.

[0010] Further, at least one positioning block is also arranged on the engaging surface of the first fastener, and a positioning groove corresponding to the positioning block is arranged on the second fastener.

[0011] Further, two symmetrically arranged positioning blocks are arranged on the engaging surface of the first fastener, and a limiting clamping opening with an inward U-shaped depression is clamped between the two positioning blocks. A clamping post is arranged in the middle of the positioning groove. During assembly, the clamping post is clamped inside the limiting clamping opening.

[0012] Inclined surfaces are arranged on both side walls of the positioning groove in the engaging direction, and inclined surfaces for cooperation are also arranged on the positioning block.

[0013] Further, the second locking block and the inclined guiding block are arranged at the insertion end of the second fastener.

[0014] An arc guiding surface is arranged on the second locking block. [[ID=*]]

[0015] Further, limiting walls are arranged at the edges of the outer shells on both sides of the first fastener. A chamfered end with an arc transition is arranged on one side of the anti-slip sheet facing the limiting wall, and the chamfered end is in abutting cooperation with the limiting wall.

[0016] The magnetic parts in the first fastener and the second fastener are arranged in a rectangular shape.

[0017] Further, at least one first rope passing groove is arranged on the first fastener, and at least one second rope passing groove is arranged on the second fastener.

[0018] Further, a rotating shaft post is arranged on one side of the second fastener close to the inclined guiding block, and the limiting iron sheet is installed on the rotating shaft post.

[0019] Further, the limiting iron sheet includes a limiting iron sheet body. One side of the limiting iron sheet body is provided with the anti-sliding sheet outward, and the other side is provided with a bending sheet that is folded towards the first fastener. The included angle between the bending sheet and the limiting iron sheet body is an obtuse angle. When the first fastener and the second fastener are engaged, the end of the bending sheet is arranged above the first rope-passing groove.

[0020] Further, a rotating sheet is also provided on the outer side of the limiting iron sheet body. A rotating shaft through-hole is provided on the rotating sheet. During assembly, the rotating shaft column is installed in the rotating shaft through-hole;

[0021] A rope-passing hole is also provided on the limiting iron sheet body.

[0022] Beneficial effects

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows: On the basis of the original patent, the present utility model adds a detailed engaging part and makes an overall rounding treatment in terms of technology. In particular, the top surface of the convex platform on the outer side of the first card slot is polished into an arc surface, so that the first fastener and the second fastener can be engaged and opened more smoothly. The key innovation in this solution is the setting of the limiting iron sheet, and anti-sliding sheets are added to both outer sides of the limiting iron sheet. The design of the R angle with an arc transition is made on the anti-sliding sheet, so that when the two end fasteners are engaged, they will not automatically disengage when pushed and pulled forward, backward, or obliquely. At the same time, the anti-sliding sheet with the R angle design forms a complement with the outer edge of the shell of the first fastener, which is convenient for sliding and engaging for limiting. In this way, no matter which side of the fastener touches the ground first when it falls, under the action of the anti-sliding sheet, the two end fasteners will not be easily misaligned and disengaged, enhancing the stability during the buckling process;

[0024] At the same time, in this solution, the internal magnetic part is defined as a rectangular or square magnet. Compared with a circular magnet, the magnetic attraction range and angle are expanded, so that the fasteners can be quickly engaged at multiple angles and in multiple directions.

[0041] 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0042] Please refer to Figure 1-7, the present utility model provides a magnetic buckle technical solution: a magnetic buckle, whose structure includes a first fastener 1 and a second fastener 2 that are engaged with each other. Oppositely cooperating magnetic members are respectively embedded in the first fastener 1 and the second fastener 2, and the magnetic members are magnetic members that attract each other. When the first fastener 1 and the second fastener 2 are engaged, the magnetic members at both ends are firmly adsorbed together. The second fastener 2 is installed above the first fastener 1 during assembly. A limiting iron sheet 3 is hinged and covered above the second fastener 2. In the natural state, the limiting iron sheet 3 is adsorbed above the magnetic member inside the second fastener 2. Anti-sliding pieces 32 are provided on the two outer sides of the limiting iron sheet 3. When the second fastener 2 moves towards the first fastener 1 to the extreme position, the anti-sliding pieces 32 abut against the edge of the outer shell of the first fastener 1, that is, abut against the limiting walls 15 on both sides of the first fastener 1. During the processing, we will choose to complementarily set the limiting walls 15 and the anti-sliding pieces 32;

[0043] Among them, it should be noted that this solution is a detailed optimization based on the original patent. Therefore, there are some structural features and settings that are the same as the original solution. Specifically, at least one first block 11 and a first slot 12 are oppositely arranged on the engaging surface of the first fastener 1 along the engaging direction. Second slots 21 and second blocks 22 corresponding to the first block 11 and the first slot 12 are provided on the second fastener 2 respectively, so as to set more than one engaging position and increase the engaging effect. Inclined guiding blocks 23 are provided on both sides of the second block 22. An included angle is provided between the inclined guiding blocks 23 and the engaging surface of the first fastener 1. During the flipping process, a guiding is formed between the inclined guiding blocks 23 and the engaging surface of the first fastener 1, and at the same time, flipping interference is avoided. Among them, the inclined surface of the inclined guiding block 23 is a convex arc surface to assist flipping;

[0044] When the first fastener 1 and the second fastener 2 are attracted, the first clamping block 11 and the second clamping groove 21 are engaged, and the first clamping groove 12 is separated from the second fastener 2. At this time, both sides of the second fastener 2 are limited by the limiting wall 15, and both ends of the engaging direction of the second fastener 2 are limited by the first clamping block 11 and the first clamping groove 12 respectively. Limiting columns 13 are symmetrically arranged on both sides of the first fastener 1, and a limiting groove 24 corresponding to the limiting column 13 is arranged on the side wall of the second fastener 2. When the first clamping block 11 and the second clamping groove 21 are engaged, the limiting column 13 abuts against one side wall of the limiting groove 24. When the first clamping block 11 and the second clamping groove are separated, the limiting column 13 abuts against a limiting top block 25 on the other side wall of the limiting groove 24. That is, the distance between the two side walls of the limiting groove 24 is the distance that the second fastener 2 can move in the first fastener 1. In addition, a limiting top block 25 is arranged at the other side wall of the limiting groove 24 to prevent the second fastener 2 from continuing to move towards the first fastener 1, and at the same time provide a moving channel for the limiting column 13 during the disassembly and flipping process. It should be noted that an inclined surface is arranged on the limiting column 13 to provide a guiding function for the installation of the second fastener 2, and at the same time facilitate disassembly and avoid interference. In this solution, in order to achieve smooth insertion and extraction inside, a rounding process is adopted in the process of processing. Through means such as grinding and polishing, the surfaces of the internal parts of the first fastener 1 and the second fastener are smooth and without burrs, providing a better feel and improving the smoothness when the fasteners are matched;

[0045] At least one positioning block 14 is further arranged on the engaging surface of the first fastener 1, and a positioning groove 26 corresponding to the positioning block 14 is arranged on the second fastener 12. Specifically, in this embodiment, see Figure 5 and 6 , two symmetrically arranged positioning blocks 14 are arranged on the engaging surface of the first fastener 1, and a limiting clamping mouth 16 arranged in an inward U-shaped depression is clamped between the two positioning blocks 14 to facilitate positioning. A clamping column 28 is arranged in the middle of the positioning groove 26. During assembly, the clamping column 28 is engaged inside the limiting clamping mouth 16 to facilitate limiting cooperation. Similarly, the positioning groove 26 and the positioning block 14 are also subjected to a rounding process. Inclined surfaces are arranged on both side walls of the positioning groove 26 in the engaging direction, and inclined surfaces for cooperation are also arranged on the positioning block 14. In this way, during installation, the fasteners can be quickly aligned through the guiding cooperation of the inclined surfaces of the positioning groove 26 and the positioning block 14. The inclined surface design facilitates flipping and disassembly. At the same time, a limit can be formed between the positioning wall of the positioning block 14 and the wall groove of the positioning groove 26 to improve the stability of the engaging structure;

[0046] The second clamping block 22 and the inclined guiding block 23 are arranged at the insertion end of the second fastener 2. An arc guiding surface is arranged on the second clamping block 22, that is, the contact surface between the upper side of the second clamping block 22 and the inner top wall of the first clamping groove 12 is an arc surface, which is convenient for flipping the second clamping block 22;

[0047] Limit walls 15 are arranged at the edges of the outer shells on both sides of the first fastener 1. A chamfered end 321 with an arc transition is arranged on the side of the anti-sliding piece 32 facing the limit wall 15. The chamfered end 321 is in abutting cooperation with the limit wall 15. Specifically, in the processing, we designed an R angle for the chamfered end 321. In this way, when the fasteners are buckled, they will not automatically separate front and back. The limit wall 15 of the first fastener and the chamfered end 321 with the R angle design form a complement, which is convenient for sliding and buckling. At the same time, it plays a role in limiting and anti-sliding during the non-subjective flipping process, avoiding the direct misalignment and separation of the first fastener 1 and the second fastener 2 when they fall, making the whole more stable;

[0048] In order to realize the cooperation between the second fastener 2 and the limit iron sheet 3, a rotating shaft column 29 is arranged on one side of the second fastener 2 close to the inclined guiding block 23. The limit iron sheet 3 is installed on the rotating shaft column 29. Of course, the installation position of the limit column 9 here is only an example position, and the position of the rotating shaft column 29 is not limited to death. As long as it can realize the effect of the articulated installation of the limit iron sheet 3, the rotating shaft column 29 can be installed at any position on the edge of the second fastener 2. Specifically, the limit iron sheet 3 includes a limit iron sheet body 31. An anti-sliding piece 32 is arranged outward on one side of the limit iron sheet body 31, and a bending piece 34 folded towards the first fastener 1 is arranged on the other side. The included angle between the bending piece 34 and the limit iron sheet body 31 is an obtuse angle. When the first fastener 1 and the second fastener 2 are clamped, the end of the bending piece 34 is arranged above the first rope threading groove 17. When flipping, the bending piece 34 first inserts downward into the first rope threading groove 17 and then moves upward (at this time, the second fastener 2 can be separated from the first fastener 1). In use, the first fastener 1 and the second fastener 2 can move within the length distance of the limit groove. When the two fasteners are simultaneously pushed inward to the limit position, the anti-sliding piece 32 abuts against the limit wall 15, making the two fasteners unable to move inward anymore. At this time, the protruding end of the inclined guiding block 23 abuts against the bayonet outside the first clamping groove 12 of the first fastener 1. In order to realize the flipping of the limit iron sheet body 31, a rotating piece 33 is also arranged on the outside of the limit iron sheet body 31. The rotating piece 33 and the anti-sliding piece 32 are arranged in parallel front and back. A rotating shaft through hole 331 is arranged on the rotating piece 33. During assembly, the rotating shaft column 29 is installed in the rotating shaft through hole 331;

[0049] It should be noted that in this solution, the magnetic members in the first fastener 1 and the second fastener 2 are rectangular in shape (or square in shape), which avoids the problem of the traditional use of circular magnetic members where the magnetic attraction effect is concentrated in the middle and cannot achieve the multi-angle and multi-directional attraction effect, thereby enhancing the automatic attraction and matching effect of the first fastener 1 and the second fastener 2;

[0050] The specific application scenarios of this device are suitcases, school bags, backpacks, etc., which are used to connect ropes on both sides. Therefore, we provide at least one first rope threading groove 17 on the first fastener 1, and at least one second rope threading groove 27 on the second fastener 2. The ropes on both sides are respectively connected to the rope threading grooves on the corresponding side. At the same time, in order to facilitate the separation of the first fastener and the second fastener, we provide a rope threading hole 311 on the limiting iron sheet body 31, which can be used to insert a thin rope in actual use, making it easier for users to separate the first fastener 1 and the second fastener 2.

[0051] It should be noted that in this solution, the limiting iron sheet and the second fastener are arranged through the lever principle, so the second fastener can only be opened by pulling it upward; the second card slot of the second fastener corresponds to the two outward protrusions of the first card block, and when closed, the two sides of the bottom are locked very smoothly, and there will be no large-scale shaking back and forth.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
