[0002] Some supermarkets often use anti-theft magnetic clasps. At the checkout counter, a strong magnetic unlocker must be used to unlock the clasp. Failure to unlock the clasp triggers alarms installed at the entrance and exit, thus preventing theft. Strong magnetic unlockers utilize a Halbach array or some combination of opposing polarities. During the magnetic bonding process, workers must overcome the repulsive magnetic forces to bond two or more magnets together. This is laborious and inefficient, and manual bonding is difficult with strong magnets. The polar repulsion creates a safety hazard, causing the magnets to fly apart. Utility Model Content

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships based on the positions or location relationships during normal use of the product.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. The drawings of the embodiments of the present invention are provided with a coordinate system XYZ, wherein the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0025] The embodiment of the utility model provides a magnet assembly device for a strong magnetic unlocker, combined with Figure 1-5 As shown, it includes a mounting disk 1, a pushing component 3 and several magnets 4. Several limiting grooves 13 are distributed circumferentially on the mounting disk 1. The magnets 4 are slidably connected to the limiting grooves 13. Several limiting grooves 13 are connected and form a connecting cavity 14 at the center position of the mounting disk 1. The pushing component 3 is in contact with the magnet 4. A detachable cover plate 2 is provided on the mounting disk 1. The cover plate 2 is limited above the limiting groove 13. The pushing component 3 pushes the magnet 4 to slide in the limiting groove 13 so that the several magnets 4 adhere to each other after reaching the connecting cavity 14.

[0026] During the production and processing process, it is necessary to first simulate the Gauss value of magnetic components of various brands, because when low-brand magnets are assembled and formed, the Gauss value of the magnet will decay due to the repulsion of the same poles, and thus the required Gauss value cannot be achieved. According to the simulation results, a magnet 4 with strong magnetic properties is selected to improve the overall performance and reliability. Then, according to the Halbach array principle, the mutually repelling magnets 4 are bonded into a cylinder with the same poles, so as to generate the strongest magnetic field with the least amount of magnets 4. The magnet 4 can be a magnet or magnetic steel, etc. The utility model has a simple structure, is easy to install, reduces production costs and installation difficulty, meets the needs of large-scale production, and the magnetic field between the combined magnets 4 is evenly distributed, thereby improving the efficiency and power of the strong magnetic unlocker. At the same time, the use of high-performance permanent magnetic materials enhances the magnetism of the magnet 4, thereby improving the performance and reliability of the strong magnetic unlocker.

[0027] like Figure 1 and 4 As shown, in this embodiment, the limiting grooves 13 are in the shape of a rectangular parallelepiped, and there are six of them. The magnets 4 are approximately fan-shaped, and there are also six of them. After applying glue on the fan-shaped side walls of the magnets 4, they are placed in the six limiting grooves 13 respectively. Under the pushing action of the pushing component 3, they move along their respective limiting grooves 13 until they reach the connecting cavity 14, and several magnets 4 are bonded to each other in the connecting cavity 14. When the magnets 4 are bonded in the connecting cavity 14, there is still a part of them that is limited in the limiting grooves 13 and cannot move, and the cover plate 2 is limited above the limiting grooves 13, covering the connecting cavity 14, so that the magnets 4 cannot fly upward. After the glue dries, the cover plate 2 is disassembled and the bonded magnets 4 are taken out and placed in the aluminum shell to complete the assembly.

[0028] The magnet assembly device of the strong magnetic unlocker in the present invention cooperates with the mounting plate 1, the pushing component 3 and the magnet 4 so that the magnet 4 is limited in the limiting groove 13 and can only move forward in one fixed direction. In this way, when multiple magnets 4 are bonded, the limiting groove 13 can limit the magnet 4 from the left and right directions and from the bottom, and the cover plate 2 limits the magnet 4 from the top, thereby preventing the magnet 4 from shaking due to the repulsion of the same poles, so that the magnet 4 can be bonded together under the action of glue, which saves time and labor, improves efficiency, reduces labor costs, avoids the safety hazard of the magnet 4 flying off during the bonding process, and improves the quality of the assembly of the magnet 4.

[0029] The pushing assembly 3 includes a screw 31 , which is threadedly connected to the peripheral wall of the mounting plate 1 , and is slidingly connected to the limiting groove 13 . One end of the screw 31 abuts against the magnet 4 to push the magnet 4 to reach the connecting cavity 14 .

[0030] like Figure 1 and 2As shown, in this embodiment, the peripheral wall of the mounting plate 1 is provided with a plurality of screw holes adapted to fit the screw rods 31, so that the screw rods 31 and the screw holes are connected by threads. The screw rods 31 extend into the retaining grooves 13 and abut against the magnets 4 therein. When the screw rods 31 are rotated, they move along their own axis, pushing the magnets 4 into the connecting cavity 14. After the magnets 4 are bonded, the screw rods 31 are rotated in the opposite direction to return to their initial position to await the installation of the next set of magnets 4. The screw rods 31 are locked in position by the action of the threads and will not move backward due to the repulsive force between the magnets 4.

[0031] The pushing assembly 3 includes a tightening handle 32 , which is connected to one end of the screw rod 31 . The tightening handle 32 is rotated forward and backward to allow the screw rod 31 to move back and forth in the limiting groove 13 .

[0032] like Figure 1 and 2 As shown, in this embodiment, the tightening handle 32 provides convenience for rotating the screw 31. At the same time, the worker can rotate the tightening handle 32 to push the magnet 4 into the connecting cavity 14, and then pull the tightening handle 32 to further lock the position of the screw 31 to prevent the screw 31 from moving under the action of the magnetic force between the magnets 4, making the structure more stable and reliable.

[0033] The magnet 4 is provided with a first end surface 41 . The first end surface 41 is a plane and is suitable for abutting against the screw 31 .

[0034] In the conventional sector magnet 4, the first end surface 41 is an arc surface, such as Figure 2 and 5 As shown, in this embodiment, the first end surface 41 is set to be a plane, so that the screw rod 31 is more closely fitted when it abuts against the first end surface 41, and the pushing effect is better, and it is not easy to slip and shake.

[0035] Notches are provided on both the left and right sides of the magnet 4 . A second end surface 42 is provided on the notch. The second end surface 42 abuts against the inner wall of the limiting groove 13 .

[0036] like Figure 2 and 5 As shown, in this embodiment, the second end surface 42 is a flat surface. The second end surface 42 allows the magnet 4 to fit more closely with the inner wall of the limiting groove 13, thereby improving the limiting effect and preventing the magnet 4 from shaking left or right. Furthermore, when applying glue to the sector-shaped inner wall of the magnet 4, the second end surface 42 does not need to be applied. This does not affect the adhesion between the magnets 4 and also prevents the inner wall of the limiting groove 13 from being stuck with glue.

[0037] After the magnets 4 are bonded, a gap is formed between the two adjacent second end faces 42 and the inner wall of the connecting cavity 14. The gap can effectively prevent the glue from overflowing and drying on the inner wall of the connecting cavity 14, thereby causing difficulty in demoulding.

[0038] The magnet assembly device further includes a magnetic column 5 . The magnet 4 is a sector-shaped body. The magnetic column 5 abuts against the sector-shaped inner arc surface of the magnet 4 . The magnetic column 5 fits with several of the magnets 4 .

[0039] like Figure 5 As shown, in this embodiment, the inner curved surfaces of several magnets 4 are bonded to the outer periphery of the magnetic column 5. During installation, glue is first applied to the outer periphery of the magnetic column 5. Then, the magnetic column 5 is bonded to the inner curved surface of any magnet 4. The magnetic column 5 slides along with the magnet 4 in the retaining groove 13 into the connecting cavity 14, where it is bonded to the other magnets 4. The diameter of the magnetic column 5 is smaller than the width of the retaining groove 13.

[0040] The cover plate 2 is made of a transparent material, and the center of the cover plate 2 and the center of the mounting plate 1 are on the same axis.

[0041] like Figure 1 and 2 As shown, in this embodiment, the cover plate 2 is an acrylic transparent plate. The transparent cover plate 2 is provided so that the user can observe the bonding condition of the magnet 4 in the connecting cavity 14 and whether the screw 31 is pushed into place through the cover plate 2, which is more convenient and does not affect the limiting effect above.

[0042] The mounting plate 1 includes a plate body 11 and a bottom plate 12 that are detachably connected to each other. The cover plate 2 is detachably connected to the plate body 11 . The upper and lower ends of the magnet 4 abut against the cover plate 2 and the bottom plate 12 respectively.

[0043] like Figure 3 As shown, in this embodiment, the bottom plate 12 is made of bakelite, and the upper and lower ends of the disk body 11 are connected to the cover plate 2 and the bottom plate 12 by bolts. This prevents the magnets 4 from collapsing due to magnetic repulsion during bonding, thereby confining the magnets 4 within the connection cavity 14 and preventing them from moving, thereby completing bonding within the connection cavity 14. After bonding the magnets 4, the cover plate 2 and bottom plate 12 can be disassembled to clean any residual glue that has overflowed from the surface. In other embodiments, the bottom plate 12 and the disk body 11 can also be integrally formed.

[0044] An opening 131 is left between the cover plate 2 and the limiting groove 13 . The opening 131 is located at an end of the limiting groove 13 away from the connecting cavity 14 . The opening 131 is convenient for placing the magnet 4 .

[0045] like Figure 1 and2 As shown, in this embodiment, the cover plate 2 is circular and does not completely cover the limiting groove 13. The radius of the cover plate 2 is smaller than the length of the limiting groove 13, so that an opening 131 is left on the limiting groove 13. The user can place the magnet 4 into the limiting groove 13 through the opening 131, which is more convenient.

[0046] Another embodiment of the present invention provides a sector-shaped magnetic assembly, including the magnet assembly device of the strong magnetic unlocker as described above.

[0047] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present utility model.
