Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the disclosure of a method for easily attaching a female stopper in an engaging tool using a permanent magnet.

Therefore, in the conventional engagement tool of this stock, a mounting washer with a leg piece was fixed to the non-adhesive surface of the ferromagnetic plate of the female stopper, but When the bag (bag, bag, etc.) is made of one piece of material, there is a risk of injury because there is a leg piece on the 15th side of the material.

The present invention has been devised especially in view of the inconveniences in the prior art, and includes providing a retainer with a funnel-shaped caulking tube to caulk the object to be attached. It is designed to ensure secure attachment and safety.

Therefore, in order to achieve an appropriate effect on the above characteristics, the present invention has the gist of its configuration by providing a hole in the direction of the magnetic pole surface.
: A ferromagnetic plate (2) is attached to one magnetic sliding surface of the established permanent magnet fl), and a ferromagnetic plate (3) is attached and detachably attached to the other 4m pole surface. A ferromagnetic rod (4) protruding from the surface of the chain plate (3) or plate (3) has a ferromagnetic rod (4) protruding from the surface of the chain plate (3) or plate (3). In the engagement JL, which is magnetically attached and removably brought into contact with the three surfaces of the protrusion (3), a funnel-shaped caulked tube (!
5) The peripheral folded tsuba (6) a of the flat plate (6) attached on the three sides of the horizontally extended tsuba (5) is referred to as f413).
a The mounting member that is immersed in the extract is recorded in the previous record (2
) side so that the lithographic plate (6) side is in contact with the plate side (
2), the end of the rod (4) inserted through (6) that protrudes into the housing 15) of the narrow frame part (4)a
), and is intended to be crushed and caulked on the surface, and considerable design changes are planned to make it resilient to the gist of such a configuration.

Hereinafter, details of the present invention will be explained with reference to a typical embodiment shown in the drawings. (1) is a magnet with holes ('11) formed from one magnetic pole surface to the other magnetic pole surface, On the other hand, a ferromagnetic plate (2) is attached to the magnetic pole surface, and the magnet (1) and plate (2) are attached to a plate-shaped case made of a non-magnetic material, which has a hole communicating with the gap (1) a. A ferromagnetic plate (3) that is fitted and fixed in one direction.The ferromagnetic plate (3) is used to attract the magnet fil.
A ferromagnetic rod (4) is caulked through the plate (2) and the planar plate (6) in the direction of the attracting surface of the previous recording (2), and a funnel-shaped rod is attached to the planar plate (2). The horizontal extension flange (5) a of the caulked pipe (5) forming the rim is brought into contact, and the circumferential folded flange (6) a of the g variable t6) is rolled into the edge of the core flange (5) a8. It is. Similarly, the ferromagnetic protrusion (3) a is attached to the waist plate (3) via the flat plate (2) and the caulking tube (5).
The narrow diameter frame part (31'a) is crushed and caulked.

The present invention has a unique structure in which it is mounted diagonally upward, thereby increasing the mounting strength and eliminating the possibility of wobbling.

In addition, since what is exposed on the back side of the attachment part is a crushed caulked tube, inconveniences such as injury are prevented.

In order to explain another embodiment of the present invention, FIG.
) is used as a hanging edge (3)b to prevent horizontal displacement when it is attracted to the female stopper, and the flat plate (6) is welded and soldered to the waist plate (3)K. It was established with the help of child actors such as. Furthermore, the free end surface of the ferromagnetic rod (4) can be directly attached to and detached from the waist plate (3).

In FIG. 3, a shield plate 19 is attached to the attracting surface of the magnet (11) to provide a magnetic shielding effect.

! In Figure E4, the upper peripheral edge of the shield plate (9) attached to the attraction surface of the magnet (11) is the fourth step part (9) a, and the upper peripheral edge of the case (the upper edge of the force is bent and fastened). Finally, the suction surface of the shield plate (9) is made smooth, and the wainscot plate (3)
It has good adhesion with.

In Figures 5 and 6, the case (force is omitted and the plate (2
) The K magnet (1) and the shield plate (9) are further bonded to the magnet (1), so that the manufacturing cost can be reduced.

In addition to the shielding effect provided by the shield plate (9), the seventh suction also prevents damage to the magnetic recording of magnetic recording cards such as cash cards when the periphery of the upper surface of the case (7) is pushed upward. In addition, the rising shoulder (IF) prevents the occurrence of lateral displacement when the plate (3) is attracted by force,
That's what I got.

Figure 8 shows a magnet fi1 tilted toward the hole (1) a, a case (fitted with force) so as to tightly contact the magnet (1), and a plate (9). 3) as ε
By bringing the case into close contact with the force, it is easy to guide the male tool along the inclined surface.

In FIG. 9, a caulking tube 15) is inserted into the material to be attached and caulked.

Figure 10 shows the material to be attached and the flat plate (8) which has the same hole as the caulking tube (5), and the K caulking tube (5) inserted into the caulking tube (5).
) is caulked at the free end, allowing the flat plate (8) to make wide contact with the material to which it is attached, reducing the stress burden per unit area (
2. It is designed to withstand long-term use.

FIGS. 11 and 12 show a crimped tube (5) with K fastening members (8) 1 and (8) 1 fitted and fastened in the same manner as described above. As stated above, it is an object of the present invention to provide an engaging tool having a unique mounting structure.
