Description

[Detailed Description of the Invention] <Industrial Application Field of the Present Invention> The present invention relates to a strainer equipped with magnetic pieces to efficiently remove dust, especially iron powder, mixed in oil, fuel, etc.

<Prior Art and Its Disadvantages> In order to remove dust mixed in oil, fuel, etc., a strainer is conventionally used, which has a cylindrical bottomed frame integrally formed of plastic with a filtration net surrounding it.

However, if fine particles such as iron powder were mixed in, they would pass through the filter net and could not be removed.

<Purpose of this invention> This invention was made in view of the above circumstances.
It is an object of the present invention to provide a strainer in which magnet pieces are inserted and attached inside to prevent the magnet pieces from falling out to the outside.

<Embodiments of the present invention> Hereinafter, embodiments of the present invention will be described based on the drawings.

1 to 6 show an embodiment of the present invention.

In these figures, reference numeral 1 denotes a cylindrical bottomed frame integrally molded from plastic, which includes an annular frame 2 at one end, a circular bottom plate 3 at the other end, and four bones connecting the two. It is composed of 4a to 4d.

At the center of the bottom plate 3 is a long and thin rectangular magnet piece 5.
A rectangular opening 6 is provided for insertion. Further, the two opposing bones 4b and 4d are integrally connected by a substantially flat connecting portion 7 continuous to the bottom plate 3, and an end portion 7 is provided at the center of the connecting portion 7.
A magnet mounting hole 8 is provided in the axial direction continuous with the opening 6 of the bottom plate 3, except for the hole a. The magnet mounting hole 8 is tapered at the tip so that the magnet piece 5 is strongly clamped when pushed in.

Further, on the outer surface of the bottom plate 3, at the edge of the opening 6,
A protruding piece 11 having a locking hole 10 is provided upright, and a lid part 12 is provided upright on the opposite edge of the opening 6, facing the protruding piece 11 via a thin hinge part 13. There is. A locking pawl 14 that is locked in the locking hole 10 of the protruding piece 11 is protrudingly provided at the tip of the lid portion 12 .

Further, a filtering net 15 made of plastic or metal is provided around the bone so as to cover the gaps between the bones 4a to 4d. That is, the filter net 15 is inserted and attached to the annular frame 2 and the bones 4a to 4d during molding of the frame 1.

From the opening 6 of the bottom plate 3, push the magnet piece 5 into the magnet mounting hole 8 as shown by the arrow in FIG.
The hinge portion 13 is bent to lock the locking pawl 14 at the tip of the lid portion 12 into the locking hole 10 of the protrusion 11 to close the opening 6 as shown in FIG.

As shown in FIG. 6, the strainer with the magnet piece 5 attached thereto is inserted into the oil passage 16a of the automatic transmission 16, for example, by inserting the annular frame 2 into the stepped portion 16.
b.

As shown in FIG. 6, the dust in the oil supplied from the opening on the annular frame 2 side in the direction of the arrow is filtered by the filter net 15, and the iron powder is attracted to the magnet piece 5.

Even if the frame body 1 is warmed by the high temperature of the oil and the magnet mounting hole 8 expands due to thermal expansion, the lid part 12
Since the opening 6 is closed, the magnet piece 5 is prevented from falling out to the outside.

FIG. 7 shows another embodiment of the invention.

In this embodiment, two
Two projecting pieces 17 and 18 are erected, and the magnet piece 5
After inserting the protruding piece 1, heat it as shown in Figure 8.
7 and 18 or push them in to close the opening 6.

Note that the strainer of the present invention can be used not only for oil but also for fuel tanks.

<Effects of the Present Invention> Since the strainer of the present invention is configured as described above, (a) iron powder mixed in oil, fuel, etc. can be efficiently removed by the magnet pieces 5;

(b) Just push the magnet piece 5 in, so the magnet piece 5
Installation is extremely easy.

(c) Since the opening 6 is closed, the magnet piece 5 can be prevented from falling off.

(d) Since the iron powder is collected on the side of the magnet piece 5, a large amount of mixed iron powder is prevented from spreading throughout the filter net 15 and causing clogging.

There are various effects such as.
