Embodiment
Describe embodiment of the present utility model in detail below in conjunction with the accompanying drawings；It should be noted that the present embodiment is narrative
, it is not limited, it is impossible to which the scope of protection of the utility model is limited with this.
A kind of Self-retaining electromagnet for realizing two-way position detection, including output shaft 10, piston 11, upper end cover 7, bottom end cover
1st, guide 14, magnet steel, coil rack 6, coil 5 and housing 2, described upper end cover, bottom end cover, piston and housing are magnetic conduction material
Material, described output shaft is non-magnet material.
The upper end of output shaft is installed on upper end cover vertically, the coaxially connected piston in lower end of output shaft, and bottom end cover is positioned at work
The lower section of plug.Piston connects and composes movable part with output shaft, and position switching is carried out between upper end cover and bottom end cover.In piston
Outside be sequentially coaxially set with guide, magnet steel, coil rack, coil and housing, above-mentioned guide, magnet steel, coil rack, coil
And housing is respectively positioned between upper end cover and bottom end cover, and the top and bottom of housing are connected with upper end cover and bottom end cover respectively.
Magnet steel includes upper magnetic steel 12 and lower magnetic steel 13, the upper magnetic steel and lower magnetic steel is setting up and down and polarity is relative.
In the bottom surface of upper end cover 8, under being embedded with the upper surface of bottom end cover are switched embedded with upper felt pad 9 and upper contact
Felt pad 3 and lower contact switch 4.A fairlead, lead 17, the lower contact of upper contact switch 8 are made on described upper end cover
The lead 15 of switch 4 and the lead 16 of coil are drawn from the fairlead of upper end cover.
Operation principle of the present utility model：
During power-off, magnet steel magnetizes upper and lower end cap and piston, and upper and lower end cap has suction to piston, because piston is close
End cap it is big to its suction, therefore piston is attracted at its close end cap, realizes self-sustaining.Now, piston presses the end
The contact switch being embedded in lid, conducting state is at, and the contact switch of opposite side is off, and then passes through two
The state of individual contact switch realizes reliable position detection.When applying forward pulse current to coil, magnetic caused by electric current
Field and magnet steel magnetic field superposition, strengthen upper end cover magnetization degree, weaken bottom end cover magnetization degree, if piston is at bottom end cover,
The suction of upper end cover overcomes the suction of bottom end cover, and piston is adsorbed at upper end cover, realizes that position switches, output shaft is pushed out；
Equally, when applying negative-going pulse electric current to coil, piston is adsorbed at bottom end cover by upper end cover, and output shaft is pulled.
Above-described embodiment is served only for illustrating the utility model, and is not construed as limiting the scope of claims limitation, therefore
All equivalent variations done with content described in the utility model claims, in scope of protection of the utility model.
