A kind of direct-acting magnet keeps magnetic structure, and its design feature is, the catch bar that comprises skeleton, skeleton slides relatively conducting magnet core, is fixedly linked with conducting magnet core, magnetic conduction armature plate and the magnetic conduction heel piece that is separately positioned on both sides, skeleton front and back; Described magnetic conduction armature plate and magnetic conduction heel piece are positioned on the line stretcher of conducting magnet core glide direction; Described skeleton is around with coil, and this coil outside is provided with the magnetic Drive Structure that drives the relative skeleton of described conducting magnet core to slide, make this conducting magnet core and described magnetic conduction armature plate or magnetic conduction heel piece adhesive.
Thus, to coil, by after direct current, the conducting magnet core in coil produces induced field, identical with the intrinsic magnetic field polarity of magnetic conduction armature plate once polarity of the magnetic field, promotes iron core 3 to yoke 6 Slideslips until in yoke 6 adhesives; In like manner, when the intrinsic magnetic field polarity of polarity of the magnetic field and armature plate 1 is different, to armature plate 1 Slideslip until in armature plate 1 adhesive; Thereby promoting catch bar 2 does reciprocating linear motion.
Be below the technical scheme of further improvement of the utility model:
As a kind of concrete version, described skeleton has the central passage of holding conducting magnet core slip, and this central passage has the cross sectional shape that prevents that conducting magnet core from rotating.More preferably, the central passage of described skeleton is square hole.Further, the central passage inwall of described skeleton has the lubricated muscle of arranging along conducting magnet core glide direction, the more preferably lubricated muscle of some circular arc types, thus reduced the frictional force that conducting magnet core is free to slide.
As a kind of concrete magnetic Drive Structure form, described magnetic Drive Structure is two blocks of opposed permanent magnets that are arranged on coil outside, certainly, also can adopt the form of electromagnet that magnetic field is provided.
Further.Described conducting magnet core is connected with catch bar engaging or gummed is connected or interference is connected.Thus, being connected of conducting magnet core and catch bar can be fixed by employing garden pin force fit, or gap is pressed into a glue and fixes, or square conducting magnet core inserts the mode such as fixing of injection molded catch bar.
Further, described conducting magnet core is the flat iron core of " one " font, and thus, whole magnetic structure can be flat distribution.
As a kind of concrete mounting means of permanent magnet, on described skeleton outer wall, have draw-in groove, described permanent magnet is contained on this draw-in groove.Further, described draw-in groove bottom has hole, and more preferably square hole, to reduce the magnetic resistance of magnetic loop, realizes the minimum clearance in permanent magnet and square conducting magnet core stage casing.
Preferably, described magnetic conduction heel piece overall U-shaped.
Compared with prior art, the beneficial effects of the utility model are: it is wide to the utlity model has applicability, and compact conformation is simple, and magnetic consumption is little, and confining force is large, good anti-vibration, the feature such as anti-electromagnetic interference capability is strong, is swift in motion reliable, low in energy consumption.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
