Abstract
The utility model relates to an oil-free door closer, which consists of magnets arranged on a door frame and a dodge door, wherein the door frame is provided with a fixed magnet, and the dodge door is provided with a rotating gear train which drives the magnet of the dodge door to rotate so as to ensure the rotating magnet arranged on the dodge door to be right ahead the fixed magnet arranged on the door frame; the faced magnetic poles of the fixed magnet and the rotating magnet are opposite in polarity. Under the action of the magnetic force of opposite magnetic poles, the dodge door automatically closes in the counter-clockwise direction. The magnetic door closer needs neither power source nor hydraulic oil, thereby saving the limited oil resources.
Description
Affiliated technical field
The utility model relates to a kind of door closer.
Background technology
At present, the oil pressure door closer that people use, after use a period of time, leakage of oil easily has influence on the result of use of door closer, and wastes limited petroleum resources.
The content of invention
The purpose of this utility model provides a kind of novel nothing oil door closer, solves the problem of common door closer leakage of oil, saves limited petroleum resources.
The technical scheme that the utility model adopted is: do not have oily door closer and be made up of the magnet that is installed on doorframe and dodge gate, doorframe is equipped with fixed magnet, dodge gate is equipped with the rotor magnet that is provided with transmitting gear, the rotating shaft of transmitting gear and rotor magnet is installed on the bearing support of dodge gate, transmitting gear and idler gear engagement, the rotating shaft of idler gear is installed on the bearing support of dodge gate, the coaxial fixed gear that is installed with on the axis of the hinge axis that doorframe is connected with dodge gate, fixed gear and idler gear engagement, fixed magnet is opposite with the pole polarity that rotor magnet is faced.
Because doorframe is equipped with fixed magnet, dodge gate is equipped with the rotor magnet that is provided with transmitting gear, and fixed magnet is opposite with the pole polarity that rotor magnet is faced, and therefore door keeps closing the state of door under the effect of magnetic force.When door is opened by external force in the direction of the clock, because the coaxial fixed gear that is installed with on the axis of the hinge axis that doorframe is connected with dodge gate, the engagement of fixed gear and idler gear, the idler gear that is installed on dodge gate with dodge gate clockwise rotate and by clockwise rotating; Because the rotating shaft of transmitting gear and rotor magnet is installed on the bearing support of dodge gate, transmitting gear and idler gear engagement, so rotor magnet clockwise rotating with dodge gate by rotating counterclockwise, thereby guarantee that rotor magnet is positioned at the dead ahead of fixed magnet, fixed magnet is opposite with the pole polarity that rotor magnet is faced.After the external force of dodge gate is eliminated, under the effect of opposite pole magnetic force, dodge gate is by counterclockwise closing automatically, rotor magnet rotates counterclockwise and moves in the direction of the clock with dodge gate, keep rotor magnet to be positioned at the dead ahead of fixed magnet, fixed magnet is opposite with the pole polarity that rotor magnet is faced.
The beneficial effects of the utility model are: this does not have oily door closer and need not power supply, does not use hydraulic oil yet, does not have the problem of door closer leakage of oil, saves limited petroleum resources.

The specific embodiment
Below in conjunction with the specific embodiment the utility model is further detailed:
Nothing oil door closer shown in Figure 1, form by the magnet that is installed on doorframe and dodge gate, doorframe (1) is equipped with fixed magnet (2), dodge gate (3) is equipped with the rotor magnet (4) that is provided with transmitting gear (6), transmitting gear (6) and coaxial the fixedlying connected of rotor magnet (4), transmitting gear (6) is actively tied on the bearing support of dodge gate (3) with the rotating shaft (5) of rotor magnet (4), transmitting gear (6) and idler gear (7) engagement, the rotating shaft (11) of idler gear (7) is actively tied on the bearing support of dodge gate (3), the coaxial fixed gear (8) that is installed with on the axis of the hinge axis (9) that doorframe (1) is connected with dodge gate (3), fixed gear (8) and idler gear (7) engagement, fixed magnet (2) is opposite with the pole polarity that rotor magnet (4) is faced.
In order to guarantee that gear rotates the influence that is not subjected to magnetic force, transmitting gear (6), idler gear (7), fixed gear (8) are by the nonferromagnetic material manufacturing.
Be positioned at the dead ahead of the fixed magnet (2) that is installed on doorframe (1) in order to be installed on the rotor magnet (4) that keeps being installed on dodge gate (3), and the pole polarity that fixed magnet and rotor magnet are faced is opposite, and the number of teeth of transmitting gear (6), idler gear (7), fixed gear (8) is identical; The modulus of transmitting gear (6), idler gear (7), fixed gear (8) is identical; The axis of transmitting gear (6), idler gear (7), fixed gear (8) at grade.
Since close door when putting in place fixed magnet (2) bigger with the suction of rotor magnet (4), be provided with buffer spring (12) in doorframe (1), the elastic force of buffer spring (12) is set to littler with the suction of rotor magnet (4) than fixed magnet (2), guarantees that dodge gate (3) can closure put in place.
Claims (7)
