JP3219360U - Drop type with an outer pipe (hereinafter referred to as pair shape) bar magnet - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a pair-shaped bar magnet with an outer pipe which can easily clean a bar magnet and has little decrease in magnetic force.
SOLUTION: A pair-shaped magnet 4 is arranged side by side via a yoke 5, and is easily disposed on the outer periphery of a pair-shaped bar magnet 3 fixed by a plug 6 and a magnet pipe 7 with a means that causes little reduction in magnetic force. The outer pipe 2 is formed so as to be freely inserted and removed.

Description

  The present invention relates to a pair shape bar magnet with an outer pipe in which an outer pipe that is detachably and closely encased on the outer periphery of a pair shape bar magnet is provided.

  Various types of bar magnets have been disclosed, and examples of pair-shaped bar magnets include known ones as shown in, for example, “Patent Document 1”, “Patent Document 2”, and “Patent Document 3”.

Utility model registration No. 3140249 (Fig. 1) Japanese Patent Laid-Open No. 7-24355 (FIG. 1) JP-A-11-197615 (FIG. 1)

  The “drop type bar magnet” of “utility model registration No. 3140249” of the above “Patent Document 1” is a bar magnet in which drop type (pair shape) magnets are arranged side by side. It is. Further, as a pair-shaped magnet, not only those disclosed in “Utility Model Registration No. 3140249” but also similar ones are not investigated, but they are considered to be within the same technical scope. In general, some bar magnets are not encased in an outer pipe, but those without an outer pipe require a lot of work to clean during use, and the magnetic adhesion of foreign matter is strong, making it difficult to perform sufficient cleaning. there were. On the other hand, the pair-shaped magnet encapsulated by the pair-shaped outer pipe has a problem that the magnetic force is not reduced and the insertion / removal is not easily performed. Further, “Patent Document 2”, “JP 7-24355” and “Patent Document 3” “JP 11-197615” disclose means for removing iron powder and iron pieces adhering to the outer surface of the magnet. However, unlike the present invention, it does not place weight on the pair-shaped outer pad, etc., and is different from the present invention.

  When the bar magnets are arranged side by side, it is relatively easy to insert and remove the outer pipe (removal), and the decrease in magnetic force can be reduced. However, in the case of a bar magnet using a pair-shaped magnet, the outer pipe Also, it is made of a pair shape, and insertion into and removal from the bar magnet is not easily performed. If the gap is large with respect to the outer periphery of the bar magnet, insertion / removal is possible, but there is a problem that the magnetic force decreases. For this reason, conventionally, a pair-shaped bar magnet encapsulated by an outer pipe has not been disclosed.

  In the present invention, an outer pipe is detachably provided on the outer periphery of a pair-shaped magnet. With an outer pipe that can be easily inserted and removed, the magnetic force can be maintained within an allowable range, and the above problems can be solved. An object is to provide a pair-shaped bar magnet. The detailed technology related to the above is the know-how of the applicant of the present application and can be prevented from being disclosed.

  The present invention has been devised to achieve the above object, and the invention of claim 1 is an outer pipe in which the outer periphery of a drop-shaped (hereinafter referred to as “pair shape”) bar magnet is detachably and closely encapsulated. The outer pipe comprises a single bar magnet or a plurality of the bar magnets (a pair-shaped bar). Applicants think that magnets with outer pipes have not been disclosed in the past, and that the present invention has novelty, know-how technology, and is sufficiently inventive and worthy of application) .

  According to the pair-shaped bar magnet with an outer pipe according to claim 1 of the present invention, it is easy to insert and remove, and the magnetic force can be maintained within an allowable range, and the bar magnet can be cleaned reliably and easily. You can increase the effect.

  The shaft sectional view showing the bar magnet of the present invention encapsulated with the outer pipe.   The typical axial sectional view showing the state where an outer pipe is inserted and removed from a single pair shape bar magnet.   The AA line expanded sectional view of FIG.   The typical perspective view which shows the state which inserts / removes the same number of outer pipes to multiple (three as an Example) pair shape bar magnet.

  Hereinafter, embodiments of a pair shape bar magnet with an outer pipe of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the pair-shaped bar magnet with an outer pipe of the present invention comprises a pair-shaped bar magnet 3 and an outer pipe 2 enclosing the outer periphery. As an example, the pair-shaped bar magnet 3 is composed of a pair-shaped magnet 4 whose cross-sectional shape is shown in FIG. 2 side by side via a yoke 5, and plugs 6 and 6 on both sides to fix the whole, etc. It consists of a magnet pipe 7 and the like for holding. As shown in FIG. 3, the pair-shaped magnet 4 has a semicircular portion at the bottom, a drop-shaped portion that forms a rising mountain shape by inclining at a repose angle or a larger angle from the left and right with the lower portion in contact therewith. Become.

  The outer pipe 2 has a drop-shaped shape that encloses the outer periphery of the pair-shaped magnet 4, and has a shape that can be inserted and removed in close contact with the magnet pipe 7 as shown in FIG. 2. During cleaning, the outer pipe 2 may be pulled out of the pair shape bar magnet 1 with the outer pipe and the pair shape bar magnet 3 may be cleaned, so that reliable cleaning is performed.

  FIG. 4 shows an embodiment in which the same number of outer pipes 2 are inserted into and removed from a plurality of (three in the illustrated example) pair shape bar magnets 3 at the same time. In this form, it is necessary to easily form the outer pipe 2 in the pair-shaped bar magnet 3 without any gaps, and the technical content is know-how as described above, and is not disclosed here.

  Although the contents of the pair-shaped bar magnet 1 with an outer pipe of the present invention are as described above, the present invention is not limited to this, and the same technical category is of course applied.

  The pair shape bar magnet 1 with an outer pipe of the present invention is applied to a pair shape bar magnet of various shapes, and its usage range is extremely wide.
