Abstract
The utility model relates to a magnetic steel, particularly relates to a magnetic steel for a tool, and mainly solves technical problems that the magnetic steel quality is not good, the structure is complicated, the instantaneous impulsion when an object surface is absorbed is large, the object surface is easily damaged, large strength is needed during the separation, the usage is inconvenient and the like. The magnetic steel for the tool comprises a magnetic steel body (1), and is characterized in that the whole magnetic steel body (1) is cylindrical. One end of the magnetic steel body (1) is provided with a notch (2), M-shaped protruding blocks (3) are arranged at edges at the upper and lower ends of the notch, and a through hole (4) is arranged at the bottom of the notch.
Description
Technical field
The utility model relates to a kind of magnet steel, especially relates to a kind of instrument magnet steel.
Background technology
Magnet steel has following characteristics: need not electricity consumption, not existing does not have power supply and produces danger; Little, the white heavy and light of small product size, easy to carry; Need not clamping device during absorbent bodies, absorption affinity is strong, safe and reliable, therefore is widely used in every field.Chinese patent discloses a kind of magnet steel (Granted publication number: CN 202260651 U), it comprises left surface and right flank, frontal plane and the back plane of inner arc surface, exterior arc surface, connection inner arc surface and exterior arc surface, it also comprises left fillet surface and right fillet surface, and the left fillet surface left side, the right respectively are connected with left surface, exterior arc surface; The right fillet surface left side, the right respectively are connected with exterior arc surface, right flank; The inner arc radius of inner arc surface is larger than the outer arc radius of exterior arc surface, and interior circular arc and external arc concentric not; Each seamed edge of the left surface of magnet steel, right flank, frontal plane and back plane is equipped with fillet; Inner arc radius is than the large 0.18mm-0.25mm of outer arc radius, and left surface and right flank and horizontal plane angle are 22o-50o.But this permanent magnetism material poor quality, structure is comparatively complicated, and the moment impulse force is very large on the absorbent bodies surface, damages easily body surface, and need to could separate with very large strength the use inconvenience when separating.
The utility model content
The utility model provides a kind of instrument magnet steel, it mainly is to solve the existing magnet steel poor quality of prior art, structure is comparatively complicated, the moment impulse force is very large on the absorbent bodies surface, damage easily body surface, and need to could separate with very large strength the technical problem of use inconvenience etc. when separating.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of instrument magnet steel of the present utility model comprises the magnet steel body, and described magnet steel body integral body is cylindrical, and the one end is provided with breach, breach the upper and lower side edge be provided with the projection of " M " type, the breach bottom is provided with through hole.Directly suction is greater than 3.4KG after magnetizing for magnet steel, and suction must reach 1.715KG when the 0.27mm gap.The projection of " M " type is symmetrical arranged, and through hole is between two projections.
As preferably, the angle α of described projection edge and horizontal plane is 50-60o.Angle α the best can be 55 o.
Therefore, magnet steel body of the present utility model has a breach, and breach is provided with the projection of " M " type, and structure is comparatively simple, is not easy to damage body surface during use, and also improve greatly useful life.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Parts, position and numbering among the figure: magnet steel body 1, breach 2, projection 3, through hole 4.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of instrument magnet steel of this example, comprise magnet steel body 1, magnet steel body integral body is cylindrical, the one end is provided with breach 2, breach the upper and lower side edge be provided with the projection 3 of " M " type, the breach bottom is provided with through hole 4.The angle α of projection edge and horizontal plane is 55o.
During use, whole magnet steel is encased in the instrument gets final product.
The above only is specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
Claims (2)
1. instrument magnet steel, comprise magnet steel body (1), it is characterized in that described magnet steel body (1) is whole for cylindrical, the one end is provided with breach (2), breach the upper and lower side edge be provided with the projection (3) of " M " type, the breach bottom is provided with through hole (4).
2. a kind of instrument magnet steel according to claim 1, the angle α that it is characterized in that described projection (3) edge and horizontal plane is 50-60o.
