Embodiment Construction

[0009] The present invention is further described below in conjunction with specific embodiment:

[0010] The magnetic door closer shown in Figure 1 is composed of magnets installed on the door frame and the movable door. The door frame (1) is equipped with a fixed magnet (2), and the movable door (3) is equipped with a rotating magnet with a rotating gear (6). (4), the rotating gear (6) is coaxially fixedly connected with the rotating magnet (4), and the rotating shaft (5) of the rotating gear (6) and the rotating magnet (4) is movably matched on the bearing seat of the dodge door (3), and the rotating Gear (6) meshes with intermediate gear (7), and the rotating shaft (11) of intermediate gear (7) is dynamically matched on the bearing seat of dodge door (3), and the hinge shaft ( 9) is coaxially fixedly installed with a fixed gear (8) on the axis, the fixed gear (8) meshes with the intermediate gear (7), and the polarity of the fixed magnet (2) is opposite to that of the rota...

Abstract

The invention relates to a magnetic force door closer, which comprises magnets which are mounted on a door frame and a moveable door, the door frame is equipped with a fixed magnet, the moveable door is equipped with a rotating gear wheel group which drives the magnet of the moveable door to rotate, thereby guaranteeing a rotating magnet which is mounted on the moveable door to be positioned on the dead ahead of the fixed magnet which is mounted on the door frame, polarities of magnet poles which are faced by the fixed magnet and the rotating magnet are opposite, the moveable door is automatically closed according to the contraclockwise direction under the function of unlike pole magnetic force, the magnetic force door closer does not need a power supply and hydraulic oil, which saves limited oil resources.

Description

Technical field [0001] The invention relates to a door closer. Background technique [0002] At present, the oil pressure door closers used by people are prone to oil leakage after being used for a period of time, which affects the use effect of the door closers and wastes limited oil resources. content of the invention [0003] The purpose of the present invention is to provide a new magnetic door closer without hydraulic oil, which can solve the problem of oil leakage of ordinary door closers and save limited oil resources. [0004] The technical solution adopted in the present invention is: the magnetic door closer is composed of magnets installed on the door frame and the movable door, the door frame is equipped with a fixed magnet, the movable door is equipped with a rotating magnet with a rotating gear, and the rotating shaft of the rotating gear and the rotating magnet is installed On the bearing seat of the movable door, the rotating gear meshes with the intermedi...
