Abstract

The invention relates to a magnetic door closer hinge which is composed of a hinge and a door closing device, wherein the hinge is composed of a left blade, a right blade and a hinge shaft; the door closing device is composed of a magnetic hinge and an elastic component; the magnetic hinge is formed by mutually-hinged chain pieces which are connected with magnets; the polarities of magnetic poles of the end faces of the adjacent magnets are opposite; one end of the magnetic hinge is connected with the left blade; the other end of the magnetic hinge is connected with the right blade; one end of the elastic component is connected with the left blade; and the other end of the elastic component is connected with the right blade. According to the magnetic door closer hinge, a door is closed by using the combination of the elastic force of an extension spring and the magnetic attraction force of the magnetic hinge, hydraulic oil is not needed to be used, and limited oil resources are saved, therefore, the magnetic door closer hinge is beneficial to environment protection.
