Description
Technical field
The present invention relates to a kind of Magnetic circuit switch that is used for opening and closing permanent magnetism equipment magnetic field sources.
Background technology
At present, rare earth permanent-magnetic material is applied to the equipment and the occasion of various use permanent magnetic fields more and more widely, but in the permanent magnetism equipment, the closing problem of permanent magnetic field does not obtain fine solution all the time, prior art generally is that permanent magnetic field is added opposing magnetic field balance in addition, but all exist following defective: 1, balance point is difficult grasps, and adds leakage field, often causes the phenomenon of big (promptly closing not thorough) of service area remanent magnetism; 2, because the magnetic circuit gap can not be designed greatlyyer, thereby the working area field degree of depth that is provided is dark inadequately, only has stronger Surface field intensity, has limited to its scope of application.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of compact conformation, magnetic field to close thoroughly and be easy to obtain stronger working area field.
Magnetic circuit switch of the present invention includes the housing of a permeability magnetic material, the opening of this housing down, at least two magnetic conductive axis that can rotate along the axle center of himself are arranged in housing, each magnetic conductive axis is parallel to each other, each magnetic conductive axis middle part is provided with interlayer, in interlayer, be fixed with the rotary magnet of the permanent magnetic material that can together rotate with magnetic conductive axis, between per two magnetic conductive axis an iron core is arranged, above each iron core, be mounted with the top magnet of permanent magnetic material, described iron core and top magnet all are fixed as one with housing, when magnetic circuit is in open mode, interlayer opening in the magnetic conductive axis is an above-below direction, and the width of interlayer is the magnetic circuit gap, at this moment two rotary magnets around each iron core and a top magnet at this iron core top, near the surface of iron core, its magnetic direction is all simultaneously towards iron core or deviate from iron core simultaneously at their.
In order to obtain bigger magnetic field intensity, in the iron core both sides, the top of each magnetic conductive axis also can be mounted with the side magnet, side magnet and housing are fixed as one, and the magnetic direction of the surface of the close iron core of rotary magnet when the side magnet is opened with magnetic circuit at its magnetic direction near the surface of iron core below it is identical.Under situation, can not have rotary magnet in the interlayer of magnetic conductive axis yet, and be a dead slot with side magnet.
Advantage of the present invention is: 1, when magnetic circuit is opened, be distributed with magnet on three directions around each iron core, and the magnetic direction of each magnet all with iron core in opposite directions or opposing, at this moment permanent magnetic circuit is a kind of magnetism-collected structure around iron core, also be a kind of open magnetic circuit simultaneously, can form stronger magnetic field (as Fig. 1, Fig. 3) at service area A, and by adjusting iron core size and magnetic circuit gap, just can change the magnetic field degree of depth of service area, to adapt to different use occasions; 2, in the time will closing magnetic field, magnetic conductive axis and rotary magnet can be turned over 90 °, just in time fill the magnetic circuit gap position of magnetic conductive axis, play the effect in mask region magnetic field, this moment, permanent magnetic circuit was a kind of inner closed magnetic circuit, as long as magnetic conductive axis material magnetic property is enough good and the material of the magnetic conductive axis of participation masked segment is abundant, just the stray field of service area can be controlled near zero magnetic field.
