[0001] The utility model relates to the magnet field, concretely points to one kind and improves single-sided magnet with small area strong power adsorption. BACKGROUND

[0002] Single-sided magnet refers to the magnet with one side magnetic and the other side weak magnetic, and this kind of magnet is widely used in various gift boxes and stationery.

[0003] The processing mode of the existing single-sided magnet is to wrap one side of the double-sided magnet with special treated galvanized iron sheet, so that the magnetic property of the wrapped side is shielded, the magnetic force is refracted to the other side, the magnetic property of the other side is enhanced, thereby forming a special magnet with only single-sided magnetic property.

[0004] Limited by materials and technology, many single-sided magnets at present stage are to increase the magnetic force of the exposed side, and the other side still has mutual attraction magnetic property, and cannot achieve the single-sided magnet in true sense. UTILITY MODEL CONTENT

[0005] The technical problem to be solved by the utility model is that the single-sided magnet with small area strong power adsorption cannot completely achieve single-sided magnetic adsorption, and the shell surface on the other side can still be adsorbed together.

[0006] To solve the above technical problem, the technical scheme provided by the utility model is as follows: a single-sided magnet with small area strong power adsorption, which comprises a single-sided magnet composed of a special-shaped shell and a square magnet, the material of the special-shaped shell is permalloy with a nickel-plated surface layer, and the corner of the square magnet and the corner of the cavity of the special-shaped shell are arc surface structures.

[0007] As an improvement, the magnetization process of the special-shaped shell and the square magnet is after assembly.

[0008] As an improvement, the material of the square magnet is nickel-plated neodymium iron boron with a N54 brand.

[0009] As an improvement, the bottom surface of the cavity of the special-shaped shell is adhered to the square magnet by an automatic dispensing machine.

[0010] As an improvement, the cavity of the special-shaped shell is connected to the outer wall of the square magnet through a PC gasket.

[0011] As an improvement, the exposed surface of the single-sided magnet is N pole.

[0012] The utility model has the advantages that compared with prior art, the device has a layer of nickel electroplated on the special-shaped shell, the magnetic force on one side of the square magnet is better refracted through the nickel plating interlayer, the corners of the special-shaped shell and the square magnet are all arc surfaces, which can better reduce the loss of magnetic wire refraction, thereby ensuring the single-sided adsorption of the single-sided magnet and avoiding the possibility of mutual adsorption of the weak magnetic surfaces.

[0018] The utility model will be further described in detail below with reference to the drawings.

[0019] As shown in the drawings Figure 1 , 2 , 3, 4, including the single-sided magnet 3 composed of the special-shaped shell 1 and the square magnet 2, the material of the special-shaped shell 1 is a surface nickel-plated permalloy, the material of the square magnet 2 is a nickel-plated neodymium iron boron with a brand N54, and the corners of the square magnet 2 and the cavity corners of the special-shaped shell 1 are arc surface structures, the square magnet 2 adopts a nickel-plated neodymium iron boron with a brand N54, which can ensure that the square magnet 2 has good magnetism after being magnetized, according to the refraction principle of magnetic wire, the arc material is the best, and the refraction loss of right-angle material is large, therefore, the corners of the square magnet 2 and the cavity corners of the special-shaped shell 1 are processed into arc surface structures.

[0020] The cavity bottom surface of the special-shaped shell 1 is adhered to the square magnet 2 by an automatic dispensing machine, and the magnetizing process of the special-shaped shell 1 and the square magnet 2 is after assembly, and the cavity of the special-shaped shell 1 is connected to the outer wall of the square magnet 2 through a PC pad; the exposed surface of the single-sided magnet 3 is N-pole, and when assembling, the cavity of the special-shaped shell 1 is placed below the automatic dispensing machine, the amount and density of glue are controlled by the automatic dispensing machine, then the square magnet 2 is adhered in the cavity of the special-shaped shell 1, and the PC pad is used to fill the gap to prevent the square magnet 2 from falling off, and then the square magnet 2 is magnetized by a magnetizing machine. In order to ensure that the outer surface of the special-shaped shell 1 is not affected by the magnetic force, the corresponding PC plate is pasted on the outer surface of the special-shaped shell 1 to weaken the magnetism, so that the weak magnetic side cannot be adsorbed together when being scattered and placed, and only the one-way magnet of the strong magnetic side can be adsorbed.

[0021] In the specific implementation, the outer wall end of the special-shaped shell 1 is pasted on the cover of the gift box, so that the exposed surface of the single-sided magnet 3 is N-pole, and then the magnetic adsorption material is pasted on the closed end of the cover, under the adsorption of the N-pole magnetic force of the single-sided magnet 3, the cover will be fixed above the body of the gift box, and because the outer wall end of the special-shaped shell 1 has weak magnetism, the mutual attraction between the gift boxes will not occur.

[0022] The above describes the utility model and its implementation, which is not limited, and the drawings only show one of the embodiments of the utility model, and the actual structure is not limited. In summary, if a person skilled in the art is inspired, without departing from the creative purpose of the utility model, without creative design, similar structure and embodiments of the technical scheme should belong to the protection scope of the utility model.
