Technical Field

[0001] This utility model relates to the technical field of belt buckles, specifically a quick-release magnetic belt buckle. Background Technology

[0002] A belt buckle, as the name suggests, is a component used to connect and secure the two ends of a belt. In traditional belt designs, belt buckles often use simple snap or pin buckles, which can meet basic securing requirements.

[0003] However, it has obvious shortcomings in terms of ease of use and quick disassembly. The snap-on belt buckle is prone to loosening after repeated use, resulting in an unstable fixation. In addition, the snap-on buckle lacks a guide and positioning, requiring alignment and groping during insertion, which increases the cumbersome operation. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-release magnetic belt buckle that enables fast and convenient assembly and disassembly of belt buckles, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release magnetic belt buckle, comprising a connector and a snap-fit ​​structure therewith. The snap-fit ​​structure includes an insert, a sliding frame mounted on the connector, a first hook fixedly connected to the inner side of one side of the sliding frame, a matching hook cavity at the insertion end of the insert, a second hook fixedly connected to the inner side of the other side of the sliding frame, a U-shaped cavity on the insert, a matching hook groove on the inner wall of the U-shaped cavity, an embedded first magnet block mounted on the inner side of the insert, an embedded second magnet block mounted on the outer side of the connector, and adjacent surfaces of the first and second magnet blocks having opposite magnetic poles.

[0006] Preferably, the inner side of the connector has a groove that matches the sliding frame, the sliding frame is fitted with a second magnet block, and the outer side of the sliding frame is fitted with an embedded magnet strip.

[0007] Preferably, the outer side of the connector is provided with a U-shaped positioning guide groove, which communicates with the U-shaped cavity. Two matching positioning guide rods are fixedly connected to the inner side of the connector insertion end, and the two positioning guide rods are symmetrically arranged about the second magnet block.

[0008] Preferably, the first magnet block, the second magnet block, and the magnet strip are all made of neodymium iron boron magnet material.

[0009] Preferably, the front end face of the connector is equipped with a limiting structure, which includes a cover plate that contacts the outer side of the sliding frame. A rectangular groove is provided on the inner side of the cover plate, and the sliding frame is slidably connected to the rectangular groove. A long hook is fixedly connected to the inner side of one side wall of the cover plate, and two short hooks are fixed to the inner side of the other side. Two short locking cavities are provided on one side of the connector, and a long locking groove is provided on the other side wall.

[0010] Preferably, the connector and the plug are provided with a belt fixing structure, the belt fixing structure includes a pressure plate, the non-inserted end of the connector is connected to an integrally formed H-shaped telescopic buckle, the non-inserted end of the plug is provided with a pressure groove, a matching pressure plate is provided in the pressure groove, the two sides of the pressure groove are provided with sliding grooves, the two side walls of the pressure plate are fixedly connected to matching sliders, the embedded surface of the pressure groove is provided with a plurality of countersunk holes, and the pressure plate is provided with interconnected threaded holes.

[0011] Preferably, the H-shaped telescopic buckle is connected to a toggle release structure, which includes a toggle block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This system enables quick and convenient assembly and disassembly of belt buckles. During assembly, the magnetic force generated by the opposite magnetic poles of the first and second magnets guides and assists in the insertion of the connector, allowing it to be smoothly and accurately inserted into the connector. Once inserted, the first hook on the sliding frame engages with the hook cavity of the connector, and the second hook engages with the hook groove on the inner wall of the U-shaped cavity of the connector. Combined with the magnetic attraction between the magnets, these three forces work together to securely connect the connector and the connector, completing the rapid assembly. For disassembly, simply apply external force to the sliding frame to make it slide, causing the first and second hooks to disengage from their respective hook cavities and hook grooves, releasing the mechanical engagement. At this point, overcoming the magnetic force between the magnets allows the connector to be easily pulled out, achieving rapid disassembly and greatly improving user convenience.

[0014] The entire belt buckle adopts an assembly-type structure design, with each component assembled together by snap-fit. This assembly-type structure not only facilitates the processing and assembly of parts during the manufacturing process, reducing production costs, but also allows for easy replacement of any damaged component during subsequent use, eliminating the need to scrap the entire belt buckle. This effectively extends the belt buckle's lifespan and improves the product's cost-effectiveness. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 7The figure shows a quick-release magnetic belt buckle, including a connector 1 and a snap-fit ​​structure 2 that are connected to it. The snap-fit ​​structure 2 includes a plug 21. A sliding frame 23 is installed on the connector 1. A first hook 24 is fixedly connected to the inner side of one side of the sliding frame 23. A matching hook cavity 201 is opened at the insertion end of the plug 21. A second hook 25 is fixedly connected to the inner side of the other side of the sliding frame 23. A U-shaped cavity 203 is opened on the plug 21. A matching hook groove 202 is opened on the inner side wall of the U-shaped cavity 203. An embedded first magnet block 22 is installed on the inner side of the plug 21. An embedded second magnet block 27 is installed on the outer side of the connector 1. The magnetic poles of adjacent surfaces of the first magnet block 22 and the second magnet block 27 are opposite.

[0025] It is worth noting that during the assembly operation, the insertion end of the connector 21 is placed near the connector 1. As the connector 21 approaches, due to the opposite magnetic poles of the adjacent surfaces of the first magnet 22 and the second magnet 27, a magnetic force is generated between them, which guides and assists in the insertion process of the connector 21, allowing the connector 21 to be inserted into the connector 1 more smoothly and accurately. During the insertion of the connector 21, the sliding frame 23 slides on the connector 1, and the first hook 24 on one inner side of the sliding frame 23 engages with the hook cavity 201 opened at the insertion end of the connector 21. At the same time, the second hook 25 on the other inner side of the sliding frame 23 engages with the hook groove 202 opened on the inner wall of the U-shaped cavity 203 on the connector 21. The cooperation between the first hook 24 and the hook cavity 201, the cooperation between the second hook 25 and the hook groove 202, and the magnetic attraction between the first magnet block 22 and the second magnet block 27, work together to firmly connect the plug-in part 21 and the connector 1 together, achieving rapid assembly.

[0026] The principle of quick disassembly is as follows: When disassembly is required, an external force is applied to the sliding frame 23, causing it to slide in a specific direction on the connector 1. The sliding of the sliding frame 23 causes the first hook 24 and the second hook 25 to move synchronously, thereby disengaging the first hook 24 from the hook cavity 201 and the second hook 25 from the hook groove 202. At this point, the mechanical engagement between the first hook 24 and the hook cavity 201, and between the second hook 25 and the hook groove 202, is released. Although there is still a magnetic attraction between the first magnet 22 and the second magnet 27, without mechanical engagement, only an external force to overcome this magnetic force needs to be applied to easily pull the connector 21 out of the connector 1's interface, completing the quick disassembly.

[0027] Please see Figure 5 and Figure 6 The inner side of the connector 1 is provided with a groove 205 that matches the sliding frame 23. The sliding frame 23 is fitted with the outside of the second magnet block 27, and an embedded magnet strip 28 is installed on the outer side of the sliding frame 23.

[0028] The embedded magnetic strip 28 and the second magnetic block 27 interact magnetically, further enhancing the stability of the sliding frame 23 on the connector 1. When the sliding frame 23 is in the normal connection state, the embedded magnetic strip 28 and the second magnetic block 27 attract each other, causing the sliding frame 23 to fit tightly against the position of the second magnetic block 27. This ensures that the first hook 24 and the second hook 25 can be accurately locked with the hook cavity 201 and the hook groove 202, preventing wobbling or displacement. Simultaneously, the shape and size of the groove 205 match the sliding frame 23, providing precise positioning and guidance for the sliding frame 23. This ensures that the first hook 24 and the second hook 25 can accurately engage with the hook cavity 201 and the hook groove 202, thereby guaranteeing the reliability of the entire quick-release magnetic belt buckle connection.

[0029] Please refer to Figure 4 , Figure 5 and Figure 6 The outer side of the connector 21 is provided with a U-shaped positioning guide groove 204, which is connected to the U-shaped cavity 203. The inner side of the insertion end of the connector 1 is fixedly connected with two matching positioning guide rods 26, which are symmetrically arranged about the second magnet block 27.

[0030] During the connection process, the positioning guide rod 26 slides along the U-shaped positioning guide groove 204. This design provides precise guidance, allowing the connector 1 to be accurately inserted into the plug 21, avoiding connection failure or instability caused by insertion direction deviation. Furthermore, the two positioning guide rods 26 are symmetrically arranged about the second magnet block 27, further ensuring the balance and stability of the connector 1 during insertion. This makes the entire quick-release magnetic belt buckle connect more smoothly and reliably, improving ease of use and safety.

[0031] The first magnet block 22, the second magnet block 27, and the magnet strip 28 are all made of neodymium iron boron (NdFeB) magnet material. NdFeB magnet material has the advantages of high remanence, high coercivity, and high energy product, which enables the first magnet block 22, the second magnet block 27, and the magnet strip 28 to generate strong magnetic force. During the use of the quick-release magnetic belt buckle, the strong magnetic force ensures a tight and stable connection between the connector 1 and the plug 21, effectively guaranteeing the reliability and stability of the belt buckle in actual use and meeting the user's need for a secure connection. At the same time, NdFeB magnet material also has good anti-demagnetization properties; its magnetic force decays little after prolonged use, maintaining good connection performance for a long time and further extending the service life of the quick-release magnetic belt buckle.

[0032] See Figure 4 , Figure 5 and Figure 6 The front end face of the connector 1 is equipped with a limiting structure 3. The limiting structure 3 includes a cover plate 31. The cover plate 31 contacts the outer side of the sliding frame 23. A rectangular groove 35 is opened on the inner side of the cover plate 31. The sliding frame 23 is slidably connected to the rectangular groove 35. A long hook 32 is fixedly connected to the inner side of one side wall of the cover plate 31, and two short hooks 36 are fixed on the inner side of the other side. Two short locking cavities 33 are opened on one side of the connector 1, and a long locking groove 34 is opened on the other side wall.

[0033] The long hook 32 is adapted to the long slot 34, and the two short hooks 36 are adapted to the two short cavities 33 respectively. When the entire belt buckle is assembled, the cover plate 31 is engaged into the long slot 34 and the short cavity 33 by the long hook 32 and the short hook 36 respectively, realizing a stable connection between the cover plate 31 and the connector 1. At the same time, the sliding frame 23 slides in the rectangular groove 35, further guiding and limiting the connection process between the connector 1 and the plug 21, making the connection more precise and smooth, effectively avoiding offset or jamming during the connection process, further improving the reliability and stability of the quick-release magnetic belt buckle connection, and making it convenient for users to quickly complete the installation and removal of the belt buckle.

[0034] See Figure 1 , Figure 2 , Figure 5 and Figure 6 The connector 1 and the plug 21 are provided with a belt fixing structure 4. The belt fixing structure 4 includes a pressure plate 44. The non-inserted end of the connector 1 is connected to an integrally formed H-shaped telescopic buckle 41. The non-inserted end of the plug 21 has a pressure groove 45. A matching pressure plate 44 is provided in the pressure groove 45. Sliding grooves 46 are provided on both sides of the pressure groove 45. Matching sliders 47 are fixedly connected to both sides of the pressure plate 44. A number of countersunk holes 42 are provided in the embedded surface of the pressure groove 45. A series of threaded holes 43 are provided on the pressure plate 44.

[0035] The countersunk hole 42 and the threaded hole 43 are positioned correspondingly. When it is necessary to fix the belt to the belt fixing structure 4, one end of the belt is passed through the H-shaped telescopic buckle 41 and fixed by the insertion method. Then, the appropriate length is adjusted, and the other end is inserted into the pressure plate 44 area. The pressure plate 44 is placed in the pressure groove 45, so that the slider 47 slides in the sliding groove 46 to realize the positioning of the pressure plate 44 in the pressure groove 45. Then, the bolt is passed through the threaded hole 43 and screwed into the countersunk hole 42 to firmly fix the pressure plate 44 in the pressure groove 45, thereby pressing and fixing the belt. This design of the belt fixing structure 4 makes the belt buckle firmly fix the belt and is easy to operate. It can be flexibly adjusted according to the waist size of different users, which improves the practicality and versatility of the quick-release magnetic belt buckle.

[0036] Please see Figure 5 , Figure 6 and Figure 7The H-shaped telescopic buckle 41 is connected to a toggle release structure 5, which includes a toggle block 51. Inside the H-shaped telescopic buckle 41, a toggle plate 52 is rotatably connected via a toggle shaft 53. The side of the toggle plate 52 is disconnected from the adjacent side wall of the sliding frame 23. One end of the toggle shaft 53 passes through the H-shaped telescopic buckle 41 and is connected to the toggle block 51, while the other end is surrounded by a torsion spring 54.

[0037] When it is necessary to release the belt, by moving the toggle block 51, the toggle block 51 drives the toggle shaft 53 to rotate, which in turn drives the toggle plate 52 to rotate. Since the side of the toggle plate 52 is in contact with the adjacent side wall of the sliding frame 23, the rotation of the toggle plate 52 will exert a force on the sliding frame 23, causing the sliding frame 23 to move, thereby releasing the belt from its locked state. At this time, the belt can be easily pulled out from the D-shaped telescopic buckle 41, realizing the quick removal of the belt. The torsion spring 54 allows the toggle plate 52 to automatically return to its initial position under the elastic force of the torsion spring 54 after the toggle block 51 is released, facilitating the next fixing and unlocking operation. This toggle release structure 5 design further improves the convenience and flexibility of using the quick-release magnetic belt buckle.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
