Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stop using a permanent magnet, particularly the stop l.
This disclosure relates to the installation of a mounting washer in this case.

Therefore, in the past, the mounting washer for this type of fastener was attached by caulking, but it is now necessary to drill holes at appropriate locations on the mounting washer and ferromagnetic plate. This required technical skill and was prone to errors in the position of opening the culture.

The present invention has been specially devised to address these inconveniences, and it is possible to easily and quickly attach the washer to the ferromagnetic plate at the stopper ζ. This is how it was done.

The details of the present invention will be described below with reference to a typical embodiment shown in the drawings. A ferromagnetic plate (2) is attached to the magnetic pole end face of the permanent magnet, and this plate (2) is attached to the magnet (1).
Twist the bent case (5) that fits the side of the first circumference, and insert the protrusion (2) a protruding from the surface of the plate (2) into the hole (1) a. 2), and the magnet [
1) A ferromagnetic plate (3
) is brought into contact with the ferromagnetic plate, and a protrusion (3) a that is magnetically attached and detachably abuts on the protrusion (2) a protruding from the plate (2) through the hole (1) a. (3), the U-shaped non-adsorption end faces of the plates (2) and (3) are fixed by spot welding the washers (41 and (41)). This is how it was done.

The present invention contemplates considerable design changes in addition to the embodiments described above.

In Figure 2, the ferromagnetic plate (3) is placed directly on the ferromagnetic plate (2).
) The protrusions (3) a protruding from each other are magnetically brought into contact with each other.

In Fig. 3, a protrusion (2) a provided so as to rise from the plate (2) in the hole (1) a directly comes into contact with the magnetically detachable surface Q of the plate (3). It's something like that.

In Fig. 4, a rising edge (5) a of the case (5) is provided at the upper circumferential edge of the magnet (1), and the ferromagnetic plate (3)
This prevents lateral deviation in the secured state.

In FIG. 5, a shield plate (6) having a hole (6) a of the same diameter as the hole (11a) is attached to the attracting surface of the magnet (1),
A recessed step (6) b corresponding to the wall thickness of the case (5) is provided on the upper surface periphery of the shield plate (6), and a bent edge (
5) The end face of b and the end face of the shield plate (6) are made smooth so that magnetic shielding and protection from external impact of the magnet are guaranteed without reducing the magnetic attraction force of the magnet (1) in any way. It is.

Figure 6 1 In this case, the shield plate is glued to the magnet (11), and the case (5) (the bending and fastening is omitted).
, which is extremely easy to manufacture.

In Figure 7, the shield plate (6) and case (5) are shown.
is omitted.

In the present invention, the mounting is made by welding the washer (4) to the ferromagnetic plate (2), (3), or either one of them, thereby making manufacturing easy and quick, and reducing costs. For example, as shown in Figure 10 of the imperial order, the mounting is done by increasing the bottom area of the washer (4), thereby further improving the mounting strength.

In addition, in the present invention (in this case, the washer (4) is welded to the mounting surface), therefore, the object to be mounted contacts the material (for example, cloth, bag, etc.) on a flat surface and is not damaged. Moreover, the non-adhesion with the material can be corrected by the protrusion of the caulked part that accompanies conventional caulking.

As mentioned above, it is an object of the present invention to provide an effective locking fitting that can be easily and securely installed with a washer.
