[0001] This utility model relates to the field of magnetic locks, and in particular to a magnetic quick-opening and closing lock for bags. Background Technology

[0002] The magnetic quick-opening and closing lock for bags is a bag accessory that combines strong magnetic adsorption with a mechanical limiting structure. The core is to achieve instant closure through magnetic force, and unlocking by a light push or press, taking into account both portability and security.

[0003] The magnetic buckles in the existing technology are generally made of metal or plastic. They are locked in place by the magnetic base during use. There are no movable buckles. They may fall off due to vibration or stress. They also fall off after vibration or drop tests. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a magnetic quick-opening and closing lock for bags, aiming to improve the problem of locks falling off and malfunctioning during use due to the magnetic buckle relying on the magnetic base for locking.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A magnetic quick-opening and closing lock for bags includes a base plate with a threaded groove inside. A first screw is threaded into the inside of the threaded groove, and an internally threaded post is threaded into the outside of the first screw. A bottom sealing plate is fixedly connected to the upper surface of the internally threaded post. An annular groove is formed inside the bottom sealing plate, and a magnetic metal is slidably connected inside the annular groove. A first N52 neodymium magnet is fixedly connected to the lower surface of the bottom sealing plate.

[0007] Preferably, the bottom sealing plate has a groove inside, and a connecting column is installed inside the groove.

[0008] Preferably, a base is fixedly connected to the upper surface of the connecting column.

[0009] Preferably, the magnetic metal is externally secured with a locking sleeve, and the inside of the locking sleeve...

[0010] It is equipped with a second N52 neodymium magnet.

[0011] Preferably, the locking sleeve has a second screw connected to its internal thread.

[0012] Preferably, the annular groove is slidably connected with a buckle, and a metal spring is installed inside the annular groove.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, three arc-shaped magnetic metals are added to the inner side of the base in a U-shape arrangement. Each magnetic metal is arranged in a 78° ring-shaped buckle. The magnetic metals are CNC machined and are movable. The material is magnetic. When the locking sleeve approaches the magnetic metals, it automatically attracts and locks them. The magnetic metals can slide inside the annular groove, thereby preventing them from falling off during use due to upward stress or vibration.

[0015] 2. In this utility model, three arc-shaped buckles are added to the inner side of the base in a U-shape arrangement, which, together with the metal spring sheet, form a locking function. The buckles are made of non-magnetic metal material and are assembled into the base. When the locking sleeve approaches the buckle, the buckle can slide inside the annular groove and press the metal spring sheet outward. The metal spring sheet, through the release of elasticity, presses the buckle inward to lock the locking sleeve, thereby preventing it from falling off during use due to upward stress or vibration.

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

[0024] Example 1

[0025] Reference Figures 1-3 An embodiment of this utility model provides a magnetic quick-opening and closing lock for bags, including a base plate 1, a threaded groove 2 inside the base plate 1, a first screw 3 threadedly connected inside the threaded groove 2, an internal threaded post 4 threadedly connected outside the first screw 3, a bottom sealing plate 5 fixedly connected to the upper surface of the internal threaded post 4, an annular groove 6 inside the bottom sealing plate 5, a magnetic metal 7 slidably connected inside the annular groove 6, and a first N52 neodymium magnet 8 fixedly connected to the lower surface of the bottom sealing plate 5.

[0026] Specifically, the first screw 3 connects the base plate 1 and the internal threaded post 4 through the threaded groove 2. Three arc-shaped magnetic metals 7 are added to the inside of the base 11 in a U-shape arrangement. Each magnetic metal 7 forms a 78° ring-shaped buckle. The magnetic metals 7 are CNC machined and are movable metals made of magnetic material. They are assembled into the base 11. When the locking sleeve 12 approaches the magnetic metals 7, it automatically attracts and locks them. The magnetic metals 7 can slide inside the annular groove 6, thereby preventing them from falling off during use due to upward stress or vibration.

[0027] Reference Figure 3 The bottom plate 5 has a groove 9 inside, and a connecting column 10 is installed inside the groove 9. The upper surface of the connecting column 10 is fixedly connected to the base 11.

[0028] Specifically, there are two connecting posts 10 on the lower surface of the base 11, and two grooves 9 inside the bottom plate 5. The two connecting posts 10 and the two grooves 9 are on the same vertical line. The connecting posts 10 are fixedly connected to the lower surface of the base 11, and the base 11 is connected to the bottom plate 5 through the grooves 9 inside the bottom plate 5.

[0029] Reference Figure 4 The magnetic metal 7 is externally attached to a locking sleeve 12, and a second N52 neodymium magnet 13 is installed inside the locking sleeve 12. A second screw 14 is threadedly connected inside the locking sleeve 12.

[0030] Specifically, the locking sleeve 12 is engaged with the magnetic metal 7 by pressing, while the second N52 neodymium magnet 13 and the first N52 neodymium magnet 8 are strongly magnetically attracted to each other, making the locking sleeve 12 and the magnetic metal 7 more securely engaged. The locking sleeve 12 has a second screw 14 connected to its internal thread, which can better fix the second N52 neodymium magnet 13 inside the locking sleeve 12.

[0031] Example 2

[0032] Reference Figure 5 The annular groove 6 has a sliding connection with a buckle 15, and a metal spring 16 is installed inside the annular groove 6.

[0033] Specifically, three arc-shaped buckles 15 are added to the inner side of the base 11 in a U-shape arrangement, which, together with the metal spring sheet 16, form a locking function. The buckles 15 are made of 430 material and are installed into the base 11. When the locking sleeve 12 approaches the buckle 15, the buckle 15 can slide inside the annular groove 6 and push the metal spring sheet 16 outward. The metal spring sheet 16, through the release of elasticity, pushes the buckle 15 inward, thereby locking the locking sleeve 12 and preventing it from falling off during use due to upward stress or vibration.

[0034] Working principle: Three arc-shaped magnetic metals 7 are arranged in a U-shape on the inner side of the base 11. Each magnetic metal 7 forms a 78° ring-shaped fastener. The magnetic metals 7 are CNC machined and are movable metals made of magnetic material. They are assembled into the base 11. When the locking sleeve 12 approaches the magnetic metal 7, it automatically attracts and locks. The magnetic metal 7 can slide inside the annular groove 6, thereby preventing it from falling off during use due to upward stress or vibration.

[0035] Three arc-shaped buckles 15 are arranged in a U-shape on the inner side of the base 11, which work with the metal spring 16 to form a locking function. The buckles 15 are made of non-magnetic metal material and are installed in the base 11. When the locking sleeve 12 approaches the buckle 15, the buckle 15 can slide inside the annular groove 6 and push the metal spring 16 outward. The metal spring 16, through the release of elasticity, pushes the buckle 15 inward to lock the locking sleeve 12, thereby preventing it from falling off during use due to upward stress or vibration.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
