Abstract

See full text

The present invention relates to the technical field of door closers, and particularly discloses an electromagnetic release door closer. The electromagnetic release door closer comprises a door closer body, a slide rail, and a rocker arm, one end of the rocker arm is articulated with the door closer body, wherein the slide rail is provided with a slide groove and a slide cavity which are parallel to each other, a through slot which is parallel to the slide groove is arranged between the slide groove and the slide cavity, wherein an electromagnetic limiting mechanism can be fixed at any position in the slide cavity. In the electrified state of an electromagnet, an electromagnetic attracting plate and the electromagnet are in a fixed state under the action of magnetic force, a limiting latch bolt is located in the slide groove, and is used to limit the sliding of a slider in the slide groove, and under this state, the slider can slide freely between the limiting latch bolt and one end of the slide groove, that is, a door leaf can move freely between a position limited by the limiting latch bolt and a maximum opening position. The defect that a door leaf can only be fixed in one specific state in the prior art is overcome, the range of adjustment is wider, and the electromagnetic release door closer is more convenient to use, and can meet more use requirements.
