Embodiment

In order more clearly to explain the present invention, below in conjunction with accompanying drawing, the present invention is further described.

Refer to Fig. 1, a kind of combined electrical magnet provided by the invention, comprises shell 8, the first fixture 2, the first sliding part 1, the second fixture 4, the second sliding part 3, the first cover plate 5, the second cover plate 6 and the 3rd cover plate 7;

The first cover plate 5 is fixed on shell 8, surrounds the first cavity with shell 8, and the first fixture 2 is fixed in the first cavity, and the first sliding part 1 and the first fixture 2 are slidably connected; The first fixture 2 comprises that First Line ring framework 21, the first iron core 24, pad 22 and magnet 23, the first iron cores 24 are fixed in First Line ring framework 21, and pad 22 is fixedly connected with First Line ring framework 21, and magnet 23 is fixedly connected with pad 22; The first sliding part 1 comprises the first slide bar 12, push rod 13, the first spring 11 and block 14, push rod 13 one end are fixedly connected with the first slide bar 12, the other end is fixedly connected with block 14, block 14 is placed in the first cavity outside, the first spring 11 is placed in the first cavity outside, one end leans in the end of the first slide bar 12, and the other end leans on the first cover plate 5;

The second cover plate 6 and the 3rd cover plate 7 are fixed on shell 8, and the two and shell 8 surround the second cavity, and the second fixture 4 is fixed in the second cavity, and the second sliding part 3 and the second fixture 4 are slidably connected; The second fixture 4 comprises that the second coil rack 41 and the second iron core 42, the second iron cores 42 are fixed in the second coil rack 41; The second sliding part 3 comprises the second slide bar 31, the second spring 32, connector 33 and banking stop 34, the second spring 32 is placed in the second cavity outside, its one end leans on the second cover plate 6, the other end leans in the second slide bar 31 ends, connector 33 is fixedly connected with the second slide bar 31 through banking stop 34, and banking stop 34 is flexibly connected with shell 8;

First Line ring framework 21 one end are electrically connected with the first electric connection line 91, and the other end is electrically connected with the second electric connection line 92; Described second coil rack 41 one end are electrically connected 93 line electrical connections with the 3rd, the other end is electrically connected with the 4th electric connection line 94.

The first spring 11 and the second spring 32 are volute spring.

Shell 8 is " L " shape, and is one-body molded.

With reference to Fig. 3 and Fig. 4, the concrete course of work can be divided into three phases:

Reset: the 3rd electric connection line 93 and the 4th electric connection line connect 94 and power connection, the second coil rack 41 is switched on, produce electromagnetic force, attract the second slide bar 31, the motion of the second slide bar 31 drives coupled connector 33 to move, connector 33 compresses the second spring 32, and drives banking stop 34 to move inwards in vertical state, no longer keeps out the first slide bar 12.The first slide bar 12, under the elastic force effect of the first spring 11, moves downward, until blocked by block 14.

Closed: the first electric connection line 91 connects positive source, and the second electric connection line 92 connects power cathode.Now First Line ring framework 21 is switched on, and produces electromagnetic force, and consistent with the magnetic force direction of magnet 23.Under the acting in conjunction of magnet 23 and electromagnetic force, the first slide bar 12 moves upward rapidly, compression the first spring 11.After motion finishes, the second spring 32 is upheld, and outwards moves, in heeling condition at the effect lower limit bit slice 34 of the second spring 32.After power-off, the first slide bar 12 keeps motionless under the attraction effect of magnet 23, and state is not at this moment very stable, if the first slide bar 12 has departed from magnet 23, banking stop 34 can prop up the first slide bar 12.

Open: the 3rd electric connection line and the 4th electric connection line connect and power connection, the first electric connection line 91 connects negative pole simultaneously, and the second electric connection line 92 connects positive pole.

The second coil rack 41 is switched on, and produces electromagnetic force, attracts the second slide bar 31, the motion of the second slide bar 31 drives coupled connector 33 to move, connector 33 compresses the second spring 32, and drives banking stop 34 to move inwards in vertical state, no longer keeps out the first slide bar 12.

First Line ring framework 21 is switched on, and produces electromagnetic force, and contrary with the magnetic force direction of magnet 23, the magnetic force that electromagnet 23 produces with magnet 23 is less than the elastic force of the first spring 11, and the first slide bar 12 moves downward.After power-off, the first spring 11 discharges completely.

In actual applications, utilize the just switch of energy control circuit of " opening " and " closure " two states.

In the present embodiment, the first spring 11 and the second spring 32 are volute spring, can take in addition the spring of other types, as long as the first spring 11 can drive the first slide bar 12 along axial-movement, the second spring 32 can drive the second slide bar 31 along axial-movement.

In the present embodiment, shell 8 is " L " shape, and the shape of shell 8 is not limited to this, as long as can lay the first sliding part 1, the first fixture 2, the second sliding part 3 and the second fixture 4, and can realize coordinating of banking stop 34 and the second slide bar 31.

Disclosed is above only several specific embodiment of the present invention, but the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
