[0005] The technical solution provided by the present invention is as follows:

[0006] A rotary magnetic buckle structure comprises:

[0007] A first connecting portion, wherein a first groove is provided on the first connecting portion, and an opening is provided on one side of the first groove;

[0008] A first magnet, the first magnet having at least two magnetic poles, and the first magnet being rotatably mounted in the first groove;

[0009] A buckle, the buckle is installed in the first groove, the buckle has a first end and a second end, the first end corresponds to the opening, the second end contacts the side of the first magnet, when the first magnet rotates, the side of the first magnet pushes the buckle, and the first end extends out of the opening;

[0010] A second connecting portion, wherein a receiving groove is provided on the second connecting portion, the receiving groove is adapted to the first connecting portion, a buckle-in groove is provided on a side surface of the receiving groove corresponding to the opening, the buckle-in groove is adapted to the first end, and a second groove is provided on the bottom edge of the receiving groove;

[0011] a second magnet, wherein the number of magnetic poles of the second magnet is the same as the number of magnetic poles of the first magnet, and the second magnet is installed in the second groove;

[0012] In an initial state, the opposite magnetic poles of the first magnet and the second magnet are misaligned, and when the first connecting portion and the second connecting portion are attracted, the first magnet is rotated by the magnetic force to push the first end into the buckling groove.

[0013] This technical solution uses the magnetic rotation force of the first magnet and the second magnet to push the plug buckle into the buckle slot to achieve automatic buckling of the magnetic buckle, which greatly simplifies the user's use process and improves the user's use experience. The second connecting part is provided with a buckle slot on the side of the accommodating slot. When the first connecting part and the second connecting part are connected, the plug buckle cooperates with the buckle slot to ensure the integrity of the first connecting part and the second connecting part after buckling, greatly simplifying the overall structure of the magnetic buckle and facilitating the user's carrying.

[0014] Preferably, it also includes an elastic member;

[0015] The elastic member is installed in the first groove, and the elastic member applies a force to the buckle in the opposite direction to the extending direction of the first end; wherein,

[0016] The elastic force of the elastic member is smaller than the force exerted by the first magnet on the buckle, but larger than the sliding friction force of the buckle in the first groove.

[0017] This technical solution applies a force to the buckle in the opposite direction of its extending opening through an elastic member, thereby ensuring that the first end of the buckle is always in the first groove before being fastened, thereby ensuring that the first connecting part and the second connecting part are magnetically attached, greatly ensuring the fastening of the magnetic buckle.

[0018] Preferably, it also includes a button;

[0019] A first wedge angle is provided at one end of the button;

[0020] A first through hole adapted to the button is provided on the first connecting portion corresponding to the rotation center of the first magnet;

[0021] The first magnet is provided with a second through hole corresponding to the first through hole, and the second through hole is provided with a second wedge angle matched with the first wedge angle;

[0022] In the tripped state, by pressing the button, the first wedge angle squeezes the second wedge angle to reset the first magnet, and the elastic member applies a force to the buckle to retract it.

[0023] This technical solution, through the cooperation of the first wedge angle and the second wedge angle, presses the button to realize the rotation and reset of the first magnet, and has a simple structure. More preferably, the button is always hidden in the first connection part in the initial state of the magnetic buckle, and when the first magnet rotates under the magnetic force, the second wedge angle pushes the first wedge angle to rotate, and the button is extended from the first connection part at this time, avoiding the button always being outside the magnetic buckle to affect the overall appearance, and also facilitating the user to carry.

[0024] Preferably, the first through hole extends into the first groove to form an extension portion, the second through hole and the extension portion are clearance-matched, the extension portion is provided with a notch corresponding to the first wedge angle, and the notch is larger than the rotational displacement distance of the first wedge angle.

[0025] In the technical solution, the second through hole of the second magnet is adapted to the extension portion, and a notch is provided so that the first wedge angle and the second wedge angle can be matched through the notch, thereby greatly reducing the space inside the first connecting portion and making the structure of the magnetic buckle more compact.

[0026] Preferably, it also includes a first cover plate and a second cover plate;

[0027] The first connection portion is further provided with a first mounting position, the first mounting position is adapted to the first cover plate, and the first cover plate covers the first groove;

[0028] The second connecting portion is also provided with a second mounting position, the second mounting position is matched with the second cover plate, and the second cover plate covers the second groove.

[0029] This technical solution ensures the structural integrity of the first connecting part and the second connecting part. The first cover plate is connected to the first mounting position, so that the first magnet, the buckle and the elastic member in the first connecting part are closed in the first groove, avoiding the loss of the structure and increasing the reliability of the magnetic buckle.

[0030] Preferably, the first cover plate and the second cover plate are fixedly connected to the first groove and the second groove via an adhesive layer.

[0031] The technical solution has a simple and effective connection method, and does not require any other changes to the structural features of the first cover plate and the second cover plate, thereby protecting the structural integrity of the first cover plate and the second cover plate, thereby improving the integrity of the magnetic buckle structure.

[0032] Preferably, the first magnet has a first side and a second side, and the distance from the first side to the rotation center of the first magnet is smaller than the distance from the second side to the rotation center of the first magnet;

[0033] In an initial state, the first side contacts the buckle, and when the first magnet rotates due to the magnetic force, the second side contacts the buckle.

[0034] In the technical solution, the overall structure of the first magnet is simple. In the initial state, the first side contacts the buckle, and in the buckled state, the second side contacts the buckle. Since the distance from the first side to the rotation center of the first magnet is smaller than the distance from the second side to the rotation center of the first magnet, when the first magnet rotates, the second side contacts the buckle, pushing the buckle into the buckle groove, thereby achieving the buckle engagement.

[0035] Preferably, the first side is a plane, and the second side is a curved surface.

[0036] In this technical solution, the first side is set as a plane to ensure that the buckle will not be easily extended by force. Only when the first connecting part and the second connecting part are magnetically attached, the magnetic force can push the buckle into the buckle slot, ensuring the reliability of the magnetic buckle. The second side is set as an arc surface. Since the contact area between the arc surface and the buckle is small, it is easy to complete the release.

[0037] Preferably, the other side of the first groove is provided with the opening, and the two openings are symmetrically distributed;

[0038] The two buckles are respectively installed in the first groove corresponding to the two openings;

[0039] Two buckling grooves are provided on the side of the accommodating groove corresponding to the two openings;

[0040] The two elastic members respectively apply forces opposite to the extending direction of the first end to the two buckles.

[0041] In this technical solution, two buckles are respectively arranged on both sides of the first groove. When the first connecting part and the second connecting part are connected, the two buckles are inserted into the buckle grooves at the same time, which further increases the reliability of the magnetic buckle.

[0042] A watch, comprising: a first watch strap, a second watch strap, a watch dial and any one of the above-mentioned rotating magnetic buckles; wherein:

[0043] One end of the first strap and the second strap are respectively connected to two ends of the dial, and the other end of the first strap and the second strap are respectively connected to the first connecting portion and the second connecting portion.

[0044] This technical solution uses a rotating magnetic buckle for a watch, which greatly simplifies the wearing process of the watch. At the same time, the watch solves the problem of inconvenience in children wearing the watch.

[0045] Compared with the prior art, the rotary magnetic buckle structure and the watch provided by the present invention have the following beneficial effects:

[0046] 1. The magnetic rotation force of the first magnet and the second magnet pushes the buckle into the buckle slot to realize the automatic buckling of the magnetic buckle, which greatly simplifies the user's use process and improves the user's use experience. The second connecting part is provided with a buckle slot on the side of the accommodating slot. When the first connecting part and the second connecting part are connected, the buckle cooperates with the buckle slot to ensure the integrity of the first connecting part and the second connecting part after buckling, greatly simplifying the overall structure of the magnetic buckle and facilitating the user's carrying.

[0047] 2. By cooperating with the first wedge angle and the second wedge angle, the first magnet can be rotated and reset by pressing the button, and the structure is simple. Preferably, the button is always hidden in the first connection part in the initial state of the magnetic buckle. When the first magnet rotates under the magnetic force, the second wedge angle pushes the first wedge angle to rotate, and the button is extended from the first connection part at this time, avoiding the button always being outside the magnetic buckle to affect the overall appearance, and also facilitating the user to carry.

[0065] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0066] In order to simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0067] An embodiment disclosed by the present invention refers to Figure 2 and Figure 8As shown, a rotating magnetic buckle structure includes a first connecting part 100, on which a first groove 101 is provided, wherein the side of the first groove 101 is provided with an opening 102; a first magnet 200 is rotatably installed in the first groove 101, and the first magnet 200 is a multi-pole magnet, and the first magnet 200 has at least two magnetic poles. A buckle 300 is also installed in the first groove 101, and the buckle 300 is slidably installed in the first groove 101, and the buckle 300 has a first end and a second end, the first end of the buckle 300 corresponds to the opening 102, and the second end thereof is in contact with the side of the first magnet 200. When the first magnet 200 rotates, the side of the first magnet 200 rotates to push the buckle 300, and the first end of the buckle 300 extends out of the opening 102.

[0068] The above-mentioned first connecting part 100 realizes the technical solution that the buckle 300 can be pushed out of the opening 102 when the first magnet 200 rotates. The following will specifically give the structural features of the second connecting part 400, and how the second connecting part 400 applies a force to the first magnet 200 to make it rotate when the second connecting part 400 and the first connecting part 100 are fitted and connected.

[0069] refer to Figure 2 and Figure 4 As shown, the second connecting portion 400 is provided with a receiving groove 401 adapted to the first connecting portion 100, and the side of the receiving groove 401 is provided with a buckle slot 404 corresponding to the first end of the buckle 300, and the buckle slot 404 is adapted to the first end of the buckle 300, so that the first end of the buckle 300 can be inserted into the buckle slot 404 when it extends from the opening 102. Specifically, the receiving groove 401 is also provided with a second groove 402, and the second groove 402 is used to install the second magnet 500. It should be noted that the second magnet 500 is fixedly installed in the second groove 402.

[0070] Specifically, the second magnet 500 is also a multi-pole magnet, and the number of magnetic poles of the second magnet 500 is the same as the number of magnetic poles of the first magnet 200. In the initial state, there is a certain misalignment angle between the positions of the opposite magnetic poles of the second magnet 500 and the first magnet 200. The size of the misalignment angle can be determined according to the actual situation. The corresponding misalignment angle in this embodiment is 20°. When the first connecting part 100 and the second connecting part 400 are attracted by magnetic attraction, the misalignment of the opposite magnetic poles of the first magnet 200 and the second magnet 500 generates a force that causes the first magnet 200 to rotate. The first magnet 200 rotates, and its side pushes the buckle 300. The first end of the buckle 300 extends from the opening 102 and then inserts into the buckle slot 404, thereby realizing the automatic buckling of the first connecting part 100 and the second connecting part 400, which greatly improves the user experience.

[0071] refer to Figure 1 and Figure 2 As shown, the number of magnetic poles of the first magnet 200 and the second magnet 500 is selected from magnets with four polarities, that is, the magnetic poles of the magnets are evenly arranged in a ring shape of "n", "s", "n" and "s". The use of a magnet with four magnetic poles ensures that the first magnet 200 is evenly rotated by the magnetic force, and at the same time ensures the accuracy of the rotation of the first magnet 200. In actual production, the specific number of magnetic poles of the first magnet 200 and the second magnet 500 used can be determined according to actual needs. It is sufficient to ensure that the number of magnetic poles of the first magnet 200 and the second magnet 500 is the same. The above-defined characteristics are obtained through a large number of experiments and are the optimal solution for the rotary magnetic buckle to rotate. If under special circumstances, the number of magnetic poles of the first magnet 200 and the second magnet 500 cannot be set to be the same, theoretically, if the second magnet 500 can exert a force to rotate the first magnet 200 and push the buckle 300 out of the opening 102, the solution satisfies the conditions for the rotary magnetic buckle to be connected.

[0072] Another embodiment disclosed by the present invention is as follows: Figure 1-3 As shown, based on any of the above embodiments, it further includes an elastic member 600 installed in the first groove 101, and the elastic member 600 applies a force to the buckle 300 to make the buckle 300 extend in the opposite direction. It should be noted that the elastic force of the elastic member 600 is smaller than the thrust of the side of the second magnet 500 on the first magnet 200 when the second magnet 500 rotates, but is larger than the sliding friction of the buckle 300 in the first groove 101.

[0073] This embodiment makes the overall structure more compact by arranging the elastic member 600 in the first groove 101. More preferably, the elastic member 600 always applies a force to retract the buckle 300, ensuring that the first end of the buckle 300 is in the first groove 101 before the magnetic buckle is not fastened, and preventing the first end of the buckle 300 from accidentally extending out of the opening 102 to affect the suction connection between the first connection part 100 and the second connection part 400. Specifically, in this embodiment, the two ends of the elastic member 600 are respectively connected to the first end of the buckle 300 and the side of the opening 102.

[0074] Another embodiment disclosed by the present invention, referring to Figure 3 and Figure 7As shown, on the basis of any of the above embodiments, it also includes a button 700, one end of which is provided with a first wedge angle 701, and a first through hole 104 adapted to the button 700 is arranged on the first connecting part 100, and the position of the first through hole 104 corresponds to the rotation center of the first magnet 200, and a second through hole 201 is provided on the first magnet 200 corresponding to the first through hole 104, and a second wedge angle 202 that cooperates with the first wedge angle 701 is provided in the second through hole 201. In the initial state of the magnetic buckle, the first wedge angle 701 and the second wedge angle 202 on the button 700 cooperate, the button 700 is in the first connecting part 100, and the overall structure of the first connecting part 100 remains intact.

[0075] When the magnetic buckle is in the engaged state, the first magnet 200 begins to rotate under the magnetic force, and the second wedge angle 202 on the first magnet 200 pushes the first wedge angle 701 on the button 700 to rotate, and the other end of the button 700 will extend out of the first connection part 100 through the first through hole 104. When disengaging, by pressing the other end of the button 700, the first wedge angle 701 squeezes the second wedge angle 202 to rotate and reset the first magnet 200, and the elastic member 600 pushes the plug 300 to retract, that is, the disengagement of the magnetic buckle is completed. It is worth mentioning that the other end of the button 700 is only exposed after the magnetic buckle is engaged, which greatly improves the overall aesthetics of the magnetic buckle. When disengaging, the first connection part 100 and the second connection part 400 can be disengaged by just pressing the button 700 lightly, which is suitable for different types of users.

[0076] Specifically, the first through hole 104 extends into the first groove 101 to form an extension portion, and the extension portion and the second through hole 201 are loosely matched, which is used to install the first magnet 200. The extension portion is provided with a notch 105 corresponding to the first wedge angle, which is used for the first wedge angle 701 to match with the second wedge angle 202 through the notch 105, and the notch 105 is greater than the rotational displacement distance of the first wedge angle 701. By providing the notch 105 on the extension portion of the first through hole 104, the first wedge angle 701 and the second wedge angle 202 are matched with each other, which greatly reduces the space inside the first connecting portion 100, thereby making the overall structure of the magnetic buckle more compact and convenient for users to carry. Of course, there are many ways to connect the button 700 and the first magnet 200, such as setting a rotating button 700 to rotate and reset the first magnet 200.

[0077] Another embodiment disclosed by the present invention is as follows: Figure 1-5As shown, on the basis of any of the above embodiments, it further includes a first cover plate 800 and a second cover plate 900, the first cover plate 800 is adapted to the first mounting position 103 of the first connecting part 100, the first cover plate 800 covers the first groove 101, and ensures the mutual cooperation between the elastic member 600, the buckle 300, the first magnet 200 and the button 700 in the first connecting part 100. The second connecting part 400 is provided with a second mounting position 403, the second mounting position 403 is adapted to the second cover plate 900, and the second cover plate 900 covers the second groove 402, ensuring that the second magnet 500 is set in the second groove 402 and will not fall off. Of course, the second magnet 500 can also be directly fixed in the second groove 402, either by glue connection or injection molding connection.

[0078] Preferably, the first cover plate 800 and the second cover plate 900 are fixedly connected to the first groove 101 and the second groove 402 by an adhesive layer. This connection method is simple, and no other changes are required to the structural features of the first cover plate 800 and the second cover plate 900, thereby protecting the structural integrity of the first cover plate 800 and the second cover plate 900. At the same time, the integrity of the magnetic buckle structure is also improved. In actual production, through holes or countersunk holes can be set on the first cover plate 800 and the second cover plate 900, and the first groove 101 and the second groove 402 can be connected by screws passing through the through holes or countersunk holes. This connection method is more complicated than the bonding layer fixing, but it realizes the detachable connection between the first cover plate 800 and the second cover plate 900 and the first groove 101 and the second groove 402, which is convenient for the replacement of the rotating magnetic buckle components and increases the interchangeability of the parts.

[0079] In another embodiment disclosed in the present invention, referring to Figure 1-7 As shown, based on any of the above embodiments, the first magnet 200 has a first side and a second side, wherein the distance from the first side to the rotation center of the first magnet is smaller than the distance from the second side to the rotation center, and the rotating magnetic buckle structure is in an initial state, the side where the first magnet 200 and the buckle 300 are in contact is the first side, and the side where the first magnet 200 and the buckle 300 are not in contact is the second side, and when the first magnet 200 is rotated by the magnetic force, the second side of the first magnet 200 is in contact with the buckle 300, thereby pushing the buckle 300 out of the opening 102.

[0080] As long as the first side and the second side of the first magnet 200 meet the above-mentioned limited adjustment, the buckle 300 can be pushed out when rotated by magnetic force. In order to reduce the overall structural size of the first connecting part 100, the first side is set as a plane, and the second side is set as an arc surface. The first side and the second side are set as a plane and an arc surface to cooperate with the rotating magnetic force to realize the buckle of the magnetic buckle, which greatly simplifies the internal structure of the magnetic buckle. It should be noted that the first side is set as a plane to ensure that the buckle 300 will not be easily extended by force. Only when the first connecting part 100 and the second connecting part 400 are magnetically attached, the magnetic force can push the buckle 300 into the buckle slot 404, ensuring the reliability of the buckle of the magnetic buckle. The second side is set as an arc surface. Since the contact area between the arc surface and the buckle 300 is small, it is easy to complete the release, ensuring the reliability of the release.

[0081] Another embodiment disclosed by the present invention is as follows: Figure 2 As shown, on the basis of any of the above embodiments, openings 102 are symmetrically arranged on both sides of the first groove 101, two buckles 300 are respectively installed in the first groove 101 corresponding to the openings 102, and two buckle slots 404 are respectively arranged on the side of the receiving groove 401 corresponding to the two openings 102, and two groups of elastic members 600 respectively apply forces in the opposite direction of the first ends of the two buckles 300 extending out of the openings 102. By providing two buckles 300, the reliability of the magnetic buckle fastening is greatly improved. More preferably, two elastic members 600 are arranged between the second end of the buckle 300 and the opening 102, and the two elastic members 600 are respectively located on both sides of the first end of the buckle 300. The two elastic members 600 can simultaneously apply elastic force to the buckle 300, so that the extension and insertion of the buckle 300 are more stable, and the position deviation of the buckle 300 when moving is avoided.

[0082] An embodiment disclosed by the present invention is as follows: Figure 1-8 As shown, a watch comprises a first watchband 1, a second watchband 2, a dial and any of the above-mentioned rotating magnetic buckles; wherein one end of the first watchband 1 and the second watchband 2 are respectively connected to the two ends of the dial, and the other ends of the first watchband 1 and the second watchband 2 are respectively connected to the first connecting part 100 and the second connecting part 400. By installing the above-mentioned rotating magnetic buckle on the watch, the wearing process of the watch is greatly simplified, and it is suitable for children to wear.

[0083] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
