Abstract
The utility model relates to the field of magnetic material, in particular to an induction magnetic sheet for a compass. The induction magnetic sheet comprises an induction magnetic sheet body (1) and a through hole (2) arranged on the induction magnetic sheet body (1), wherein the through hole (2) is arranged on the induction magnetic sheet body (1) in a manner of deviating from the center of the sheet body. With the arrangement, the induction magnetic sheet has good magnetic property.
Description
Technical field
The utility model relates to field of magnetic material, relates in particular to a kind of induction magnetic sheet that is used in reference to compass.
Background technology
The induction magnetic sheet that uses on the compass is provided with the through hole of distinguishing pole orientation; But the prior art through hole be provided in a side of the induction magnetic sheet in the heart; When magnetizing for the induction magnetic sheet, can hinder the intermediate magnetic line of force like this, influence the distribution of the magnetic line of force, make that the directivity that magnetizes is bad; It is poor to cause responding to magnetic sheet magnetic, and then influences the sensitivity of compass.
Summary of the invention
The utility model problem to be solved is: the induction magnetic sheet that is used in reference to compass that a kind of good magnetic is provided.
The technical scheme that the utility model adopted is: a kind of induction magnetic sheet that is used in reference to compass, and it comprises induction magnetic sheet body, is provided with through hole above the described induction magnetic sheet body, described through hole is arranged on off-centered position on the induction magnetic sheet body.
Adopt above structure compared with prior art; The utlity model has following advantage: through hole is arranged on the eccentric position on the induction magnetic sheet; Just can not influence the intermediate magnetic line of force when magnetizing like this; Induction magnetic sheet good directionality after feasible the magnetizing, and good magnetic, and then make that the compass that uses this to respond to magnetic sheet is highly sensitive.
Description of drawings
Accompanying drawing 1 is used in reference to the structural representation of the induction magnetic sheet of compass for the utility model.
As shown in the figure: 1, induction magnetic sheet body; 2, through hole.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done to further describe, but the utility model is not limited only to following embodiment.
Shown in accompanying drawing 1: a kind of induction magnetic sheet that is used in reference to compass; It is foursquare, and its center is provided with through hole 2 at two diagonal line intersections above it; Described through hole 2 is arranged on off-centered position on the induction magnetic sheet 1; Best position is near the center, does not leave too far, and just off-center a bit.
Claims (1)
1. induction magnetic sheet that is used in reference to compass; It comprises induction magnetic sheet body (1); Be provided with through hole (2) above the described induction magnetic sheet body (1), it is characterized in that: described through hole (2) is arranged on induction magnetic sheet body (1) and goes up off-centered position.
