Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a device for installing a magnet around a water pipe to prevent scale generation.

[0002]

2. Description of the Related Art Water pipes have long-term use due to the presence of impurities and organic substances in the tap water, and the scale, algae,
Corrosion occurs. This reduces the quality of tap water as drinking water and shortens the life of the water pipe.
It is empirically known that it is effective to install a magnet in a water pipe and apply magnetism in order to reduce such a problem.

As a method of installing such a magnet,
Conventionally, there have been ones in which a magnet is installed inside a water pipe by modifying a part of the water pipe itself, or two magnetic lumps are installed around the water pipe by separate belts. However, in the former case, a modified water pipe must be prepared for each diameter of the water pipe, resulting in high cost. Also, the latter is not stable because it is installed by a belt.

For this reason, a large clamp-shaped installation tool is closed with a spring in order to easily accommodate the diameter of a water pipe and to perform stable installation, and magnets are fixed on both sides inside the clamp-shaped installation tool. Therefore, a technique has been proposed in which a magnet can be installed by clamping a water pipe with an installation tool (utility model registration No. 3053192).

[0005]

However, the clamp-shaped installation tool can only install two magnets and cannot evenly surround the entire circumference of the water pipe. The present invention has been made to solve the above problems, and can easily accommodate the diameter size of a water pipe, can be installed stably, and can have a large number of magnets evenly surrounding the entire circumference of the water pipe. An object of the present invention is to provide a magnetic unit device that can be used.

[0006]

In order to solve the above-mentioned problems, a first invention is to provide a plurality of magnetic units and a belt-shaped continuous magnetic unit provided at both ends of each magnetic unit. And a fastening portion for fastening to the magnetic unit device.

The second aspect of the invention is further characterized in that the plurality is 3

And a magnetic unit device.

According to a third aspect of the invention, the pin coupling portion further increases the degree of freedom in the positional relationship between the magnetic units.
A magnetic unit device having a pin structure. In a fourth aspect of the present invention, the pin coupling portion having the two-pin structure is press-fitted over the U-shaped receiving portions formed at both ends of the magnetic unit and the U-shaped ends. A magnetic unit device comprising a pin to be attached, a swing piece penetrated by the pin, and two pin holes formed in the swing piece.

According to a fifth aspect of the present invention, the rocking piece is not penetrated to the pins at the extreme ends of the belt-like magnetic unit, and the pins at the extreme ends are bound by a binding band. It is a magnetic unit device characterized by the above. A sixth aspect of the invention is a magnetic unit device characterized in that the respective magnetic units are inclined on both side surfaces so that they are hard to come into contact with each other when they approach each other and can sufficiently approach each other.

FIG. 1 is a block diagram of an embodiment of the present invention.
~ Shown in FIG. As shown in FIG. 1, three magnetic units 3 are installed around a small-diameter water pipe 1. At both ends of each magnetic unit 3, there are pin coupling parts 5 as fastening parts.
Is provided to continuously connect the three magnetic units 3 in a belt shape. As shown in FIG. 3, each magnetic unit 3 is
It has an arc-shaped magnet 7, a cubic magnet 9, an upper portion 13 and a lower portion 15 of a plastic cover 11, and a pin coupling portion 5.

Of these, the arc-shaped magnet 7 has a quadrangular plate shape as a whole, and has an arc-shaped cross section in which both ends connected to the planar central portion 17 are bent. Central part 1 which is the recess of this bow-shaped section
Cubic magnets 9 are attracted to and held on the back surface of 7 by mutual magnetic forces. The cubic magnet 9 has a cubic shape, and the upper surface 19 of the cubic shape has the same size as the back surface of the central portion 17 of the arc magnet 7, and they are integrated in the attracted state.

The plastic cover 11 is composed of an upper portion 13 and a lower portion 15 so as to cover the bow magnet 7 and the cube magnet 9 which are integrated. The upper part 13 is an arcuate magnet 7
Has an arcuate cross section 21 for covering the arcuate cross section of
The screw 31 is screwed into the screw holes 27 and 29 formed in the inclined surface portion 23 of the first magnet 1 and the inclined surface portion 25 of the arcuate magnet 7, so that the both 13 and 9 are fixed. The bow-shaped cross section 21 has a pin coupling portion 5 at the end of the slope portion 23.

The pin coupling portion 5 has two U-shaped receiving portions 33. A pin hole 37 for press-fitting and penetrating and mounting the pin 35 is formed across both ends of each U-shape. The pin hole 37 is used for the magnetic unit 3
Has a belt-like rotation axis that is orthogonal to the longitudinal direction. Further, a swing piece 39 which is penetrated by the pin 37 is arranged. Two pin holes 41 are formed in the swing piece 39, whereby adjacent magnetic units 1 are formed.
Thus, the swing piece 39 can be shared. Rocking piece 3
The presence of 9 increases the degree of freedom of each magnetic unit 3 in the positional relationship with each other.

The lower portion 15 of the cover 11 has a substantially box shape,
The upper surface has a bow shape corresponding to the bow section of the bow magnet 7,
The interior is divided into three rooms, and the cubic magnet 19 is housed in the central room 43. Further, both side surfaces of the substantially box shape are inclined downward to form inclined surfaces 45, whereby the lower surface of the substantially box shape is also arched. Due to this inclination, the magnetic units 3 are unlikely to come into contact with each other when they approach each other, and thus can approach each other sufficiently close to each other, and can correspond to the water pipe 1 having a small diameter (FIG. 1).

The lower portion 15 of the cover 11 fits into a recess (not shown) formed inside the upper portion 13 to prevent rainwater and the like from entering the inside. Further, as shown in FIG.
Pins 35 at the outermost ends of the magnetic unit 3 continuous in a belt shape
The rocking piece 39 is not penetrated and is exposed. Using the exposed pin 35, a binding band 47
Thus, the pins 35 at the outermost ends are bound. The binding band 47 has an enlarged portion 49 formed at one end.

Lock. Since this locking is considered in the direction opposite to the insertion direction of the binding band 47 (the removal direction), the binding band 47 cannot be removed once it is tightened.

(Effects of Embodiment) As described above, since each magnetic unit 3 is continuously fastened in the belt shape having a large degree of freedom by the pin coupling portions 5 provided at both ends, the number of magnetic units is increased. By changing the above, it is easy to freely adapt to the diameter sizes of the water pipe 1 from the small diameter to the large diameter.

Since a large number of magnetic units 1 can be set by press-fitting the pins 35 via the swing piece 39, the entire circumference of a large-diameter water pipe can be evenly surrounded.
In addition, the entire magnetic unit device has a belt shape, so that stable installation can be performed. In particular, by using the pin connection, the rigidity is high in the direction orthogonal to the longitudinal direction of the belt, and the strength of the belt as a whole can be improved.

Nevertheless, the two-pin structure increases the degree of freedom in the plane where the belt can exist. Therefore, as shown in FIG. 1, the water pipe 1 having a small diameter can be sufficiently accommodated, and each magnetic unit 3 is provided on the side surface of the water pipe 1,
It can be installed facing the center of the water pipe 1.

This two-pin structure has one swing piece 39.
It is obtained by a simple structure in which two pins 35 penetrate. Further, the number of magnetic units can be easily increased even by manual work by press fitting the pin 35. Further, the combination of the bow-shaped magnet 7 and the cube-shaped magnet 9 makes it easy to generate strong magnetism. In addition, the binding band 47 is formed by using the exposed pin 35.
Since each magnetic unit 3 can be installed by magnetic force to the water pipe 1, it can be installed easily by the binding band 47.

Further, the inclined surfaces 45 on both sides of the magnetic unit 3
As a result, even if the magnets 7 and 9 are made sufficiently large and the size of the swinging piece 39 in the belt longitudinal direction is reduced, it is difficult for the magnetic units 3 to come into contact with each other as they approach each other, as shown in FIG. Water pipes that are close enough, especially small pipes 1
Can fully cope with.

May be done manually.

In the above embodiments, the combination of the arc-shaped magnet 7 and the cubic magnet 9 is used, but in other embodiments, a single magnet may be used. In the above embodiments, the binding band 47 was used for the exposed pin 35 (FIG. 2), but in other embodiments,
The binding band 47 may be wound around the entire belt-shaped continuous magnetic unit 3.

[0025]

As described above, according to the first invention, since each magnetic unit is continuously fastened in the belt shape by the fasteners provided at both ends, the water pipe can be changed by changing the number of magnetic units. It is easy to accommodate caliber sizes from small to large. Since a large number of magnetic units can be installed, the entire circumference of a large diameter water pipe can be evenly surrounded. Also,
The entire magnetic unit device is in the form of a belt, which allows stable installation.

Further, according to the second aspect of the present invention, strong magnetism is more likely to be generated, and the pin connection can improve the strength of the entire belt. Further, according to the third invention, the two-pin structure further increases the degree of freedom and can sufficiently cope with a water pipe having a small diameter.
