Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention is further described:

[0010] figure 1 The schematic diagram of the structure of the magnetic door closer when the hinge is closed and figure 2 The schematic diagram of the structure of the magnetic door closer when the hinge is opened; the magnetic door closer hinge is composed of a hinge 1 and a door closing device 2. The door device 2 is composed of a magnetic hinge 6 and an elastic element 7, the magnetic hinge 6 is composed of mutually hinged chain pieces 8, and the chain pieces 8 are connected with magnets

[0011] 9. The polarities of the magnetic poles facing the adjacent magnets 9 are opposite, so that the adjacent magnets 9 generate mutual attraction; one end of the magnetic hinge 6 is connected to the left leaf 3, and the other end of the magnetic hinge 6 is connected to the right leaf 4, Make the magnetic hinge 6 have a pulling force in the opposite direction to the opened door 20; one...

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.

Description

technical field [0001] The invention relates to a door closer, in particular to a magnetic door closer hinge. Background technique [0002] The existing hydraulic door closers often leak oil after being used for a period of time, which not only affects the use effect of the door closers, but also wastes oil resources, which is not conducive to environmental protection; a magnetic door closer that does not need hydraulic oil Hinges have become the needs of saving oil resources and environmental protection. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a magnetic door closer hinge, and reduce the consumption of oil resources. [0004] The technical solution adopted in the present invention is: the hinge of the magnetic door closer is composed of a hinge and a door closing device, the hinge is composed of a left leaf, a right leaf and a hinge shaft, the door closing device is composed of a ma...
