More Information
Summary:The utility model discloses a lock electromagnet which is provided with an electromagnet core (1). The outside part of the electromagnet core (1) is coated by a thin sheet (2). The end surface of the thin sheet (2) is provided with a close over (3) and the section shapes of the thin sheet (2) are two sections of symmetrical circular arcs. The thin sheet (2) is spliced with the close over (3). The utility model leads the thickness of the electromagnet to be lessened so as to adapt the width of the position of an original lock and realizes the exchange of locks. No changes are needed on an original gate. The utility model has the advantages of labor and time saving and simultaneously reduces the cost of changing lock. The improved electromagnet has no influence on magnetic force.
