Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment of the present utility model is related to a kind of bi-directional push-pull constant force unicoil high life electromagnet, such as Fig. 1 and Fig. 2
It is shown, including chase 1, secured core 2 and movable core 3, bobbin 4 is provided with the chase 1, the bobbin 4 is segmented
Bobbin, the upper and lower ends of bobbin 4 are wound line bag, and the direction of winding phase of the top and bottom of bobbin 4 by a copper cash 5
Together, middle part is provided with two blocks of magnet 6, the opposite polarity of two blocks of magnet 6；Top in the axle of the bobbin 4 is provided with described solid
Fixed core 2, the movable core 3 are fitted together with guide rod 7 by the twisting of bearing 9；The guide rod 7 is from the axle bottom of bobbin 4
Penetrate top to pass so that movable core 3 is located in the axle of bobbin 4, and guide rod 7 is consolidated after passing from bobbin top by guide bar head 11
It is fixed；Bottom in the axle of bobbin 4 is provided with rubber sheet gasket 10, and rubber sheet gasket 10 can be buffered when movable core moves downward
Impact, so as to improve the service life of product；The bottom of chase 1 is fixed in chase 1 by the twisting bobbin 4 of lower cover 8,
