DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the disclosure of an extremely novel and effective magnetic engaging tool that has a simple structure, has good magnetizability, and has no leakage magnetism.

Therefore, one of the main objectives anticipated in the present invention is to construct a closed circuit for appropriate magnetic flux on the magnetic pole surface and between the magnetic poles,
It is placed at a point K to maximize the magnetic flux density in the chain.

Next, one of the other main objects expected in the present invention is to effectively ensure the desired magnetic shielding by arranging such a magnetic circuit.

- One of the other main objects anticipated in the present invention is to eliminate as much as possible the air gap between the magnetic pole and the ferromagnetic member magnetized thereto, thereby reducing the gap E7 in inverse proportion to the square of the distance. This book is based on the point that it is possible to make effective use of magnetic force.

Next, one of the other main objects anticipated in the present invention is to ensure a considerable pivoting end face for the magnetically attachable master image which can be freely engaged and detached, thereby making it possible to create an accurate magnetically attached surface. The idea was to make it easier for people to get used to it.

Furthermore, various other objects anticipated in the present invention will be made clear in turn from the following description, and the present invention has various useful effects in particular due to the characteristics of the present invention. In order to achieve this, the gist of the structure is such that a suitable ferromagnetic part is covered and fixed on each magnetic pole surface of a permanent magnet, and the magnetic plate can be attached to or detached from any one of the magnetic plates. 11. A part of the ferromagnetic engaging member to be magnetically attached can be freely attached to and detached from the ferromagnetic plate or a corresponding ferromagnetic member fixedly connected to the magnetic plate. Considerable design costs associated with this project were planned.

Hereinafter, details of the present invention will be explained with reference to a typical embodiment shown in the drawings.

In addition, in order to improve the 4Ia property, a ferromagnetic plate (9) is arranged as necessary in the direction of the magnet surface of the mounting leg (7). Next, we will explain another example of magnetization illustrated in FIGS. 1 and 2. The abutting end surfaces of the magnetic rod 18) and the ferromagnetic plate 121B are

As exemplified in the figure, if the plate 121A was bent appropriately to create the required curved surface, the same effect as in the configuration described above could be achieved. Furthermore, the mounting hole 4 in the plate (21B)
By applying a considerable amount of drawing press processing to the drilling process instead of grinding, the contact end surface of the magnetic rod (5) is maximized and good magnetization is guaranteed.

The present invention can achieve specific effects of the above-mentioned characteristics by virtue of the particularly characteristic configuration described above. Therefore, this kind of magnetic retainer in the conventional example is generally the sixth type.
7 and 7, a normal magnet A is covered with a non-reefing film B, and a magnetic plate C is detachably arranged via the FiB.

However, in such a method, not only is the magnetic property extremely reduced due to the nature of magnetism, which is inversely proportional to the square of the distance between the magnetic poles, but also the magnetic flux density in the magnetic space is also It lacks firm adhesion as a fitting.

Also, the reason for this is that the stress directed in the non-magnetized direction due to the separation of the free base plate causes a four-reversal of the magnetic surface, and this separation causes sudden attenuation of the magnetic deer. It is. Furthermore,
With the removal of the cover plate, that is, the separation of the engaging end surface, magnetic lines of force are bridged between the NS and N poles, which destroys the memories in commuter passes, tickets, cash cards, and other magnetic cards, which greatly improves their usability. It is the same thing.

Our goal is to effectively rectify the defects of conventional products, and to eliminate the need for easy insertion, magnetization, and gap machining, which is considered to be relatively separable, and to provide strong magnetic attachment; and magnetic shielding. This is a book that will make you realize that. In addition, the lines of magnetic force are the plates (21A, (23B and 1 rod [5),
(81 is used as a magnetic path, and the magnetic force of the magnet (1) is focused to the maximum extent possible, and there is no room for unnecessary magnetic resistance to occur.) Furthermore, the closure of such a magnetic path makes it possible not only to create a high-unit Weber but also to provide an effective magnetic shield.

In the Kflll embroidery example, the suction surface of the machine part (5) is made into a hemispherical shape, and the machine part (5) which is abutted and attracted by this is made into a hemispherical shape. 8) Also, make the abutting end surface of the ferromagnetic plate (2) B into a rounded surface that matches the rounded surface of the machine part (5), and if necessary, make If the ffi+9

[Also, (2) When opening the fitting hole in BK, the contact end surface of the ridge machine part (5) is maximized so that a considerable amount of drawing press processing is performed instead of grinding. It promises good adsorption properties. The present invention is expected to achieve a unique effect of the above-mentioned #I characteristic due to its unique construction. In general, this kind of magnetic engagement tool in the conventional example is I.
This method is of the form illustrated in Figures R6 and 7, and would normally be one in which a magnet A is covered with a non-magnetic plate B and a suction plate C is detachably provided via the IMB. Due to the nature of magnetism, which is inversely proportional to the square of the distance between the magnetic poles, not only the attraction is extremely reduced, but the magnetic flux density in the attraction space is also relatively t-, making it difficult to secure a firm stop as an engaging tool. It lacks adhesion. Furthermore, the magnetic card storage device of the cash card was destroyed due to the influence of magnetic lines of force when the engaging end surface separated, impairing its usability. The present invention is designed to effectively rectify the defects of the conventional products, thereby ensuring easy insertion and magnetization, strong attraction, and magnetic leakage prevention effects. Therefore, I [In addition, the magnetic lines of force are focused on the ferromagnetic plates (21A, (2) B and machine part (5)% A8) as magnetic paths, and the magnetic lines are focused on the magnet (1).
