Abstract

The present invention relates to a compass calibrator capable of correcting a broken compass to prevent economic loss and prevent educational disruption.

Description

Compass Brace}

The present invention relates to a compass calibrator that can correct the change in the compass polarity of the compass.

Education sites, such as schools, use a lot of compasses at once. As you keep a large amount of compass in the process, the compass's compass will often change direction.

The broken compass is discarded or used as it is, which causes a lot of economic loss and educational confusion.

Accordingly, an object of the present invention is to provide a compass calibrator that can prevent the economic loss and the educational confusion by correcting the above-mentioned problems, that is, a broken compass.

An object of the present invention is a housing having an electromagnet to which DC power is supplied and a switch intermittently intercepting the electromagnet; It is characterized in that there is a permanent magnet fixing plate having a permanent magnet located in the upper portion of the loading portion and can be fixed to arrange the compass pole of the compass located on the pole of the electromagnet regardless of the earth magnetism.

The permanent magnet fixing plate is characterized in that the permanent magnet to form a slope to make a different distance so that the magnetic force acting on the two poles of the compass can act differently.

By allowing the broken compass to be calibrated as described above, it is possible to prevent the compass from being discarded, to prevent economic loss, and to prevent the educational disruption in education.

Figure 2 is a perspective view showing the internal structure of the compass calibrator according to the present invention.
Figure 3 is a perspective view of a compass and a compass according to the present invention.
Figure 4 is a perspective view showing the use of the compass calibrator according to the present invention.

The following describes an embodiment of the present invention with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 4, the compass calibrator 11 according to the present invention includes an electromagnet 19 to which a DC power is supplied, and a housing in which a switch 16 to control the electromagnet 19 is embedded. There are 12.

The housing 12 has a compass loading portion 13 for placing a broken compass (AC) in the upper portion where the one pole of the electromagnet 19 is located, located on the compass loading portion 13 and the compass ( There is a permanent magnet fixing plate 14 having a permanent magnet 17 capable of aligning the compass one pole of AC) to be located at the one pole of the electromagnet 19 irrespective of the earth magnetism.

One side of the housing 12 is provided with a power jack 18 is connected to the DC power source, the power jack 18 is connected by a wire 20 for electrically connecting the electromagnet 19 and the switch 16 It is.

In addition, the compass loading portion 13 is formed with a finger hole (15) into which a finger can be inserted so as to easily hold and hold the compass (AC).

The permanent magnet fixing plate 14 having the permanent magnet 17 is configured to form an inclined surface such that the compass of the compass AC can be inclined to the position where the electromagnet 19 is located.

Compass calibrator 11 configured as described above is first separated from the normal compass (NC) and the broken compass (AC) and then loaded the broken compass (AC) to the compass loading section 13 to the permanent magnet fixing plate 14 The compass of the broken compass AC is inclined toward the position of the electromagnet 19 by the permanent magnet 17.

In this state, when the switch 16 is operated, a direct current is applied to the electromagnet 19 to generate a strong magnetic force. At the same time, the compass of the broken compass AC sticks to the electromagnet 19. The compass pole is changed.

In this way, the broken compass AC is normally corrected.

Claims (3)

Located in the upper part of the compass loading section, there is a housing that has an electromagnet that is supplied with direct current power supply, and a switch for interrupting the electromagnet; And a permanent magnet fixing plate having a permanent magnet capable of aligning the compass one pole of the compass to be located at the one pole of the electromagnet regardless of the earth magnetic field. The compass of claim 1, wherein the permanent magnet fixing plate forms an inclined surface to make a different distance so that the magnetic force acting on the two poles of the compass can act differently. The compass of claim 2, wherein the inclined surface is inclined such that a small magnetic force exerts a place where the one pole of the electromagnet is located.
