After the anti-skidding lasso 50 is fixed on magnet head 41, the bottom surface of anti-skidding lasso 50 is lower than the bottom of magnet head 41
Face, antislip ring are made of rubber material.
A kind of installation steps of vertical hinged door adjustable positioner are as follows,
Installation:
1) door is closed, downward the locator magnet head 41 combined, the lower end of structure-steel framing 20 is aligned with the lower mouth of door leaf；
The edge of angle 22 is adjusted with a distance from doorframe, at least one centimetre of distance between the two；
2) locator is mounted on door leaf 80, when switching door leaf, the lower section of locator will not be contacted with bottom surface；
3) it is opened and closed door leaf, selects the center of circle of the point as floor tile circular hole 91 on the track of 43 center line of locator threaded rod warp；
4) the floor tile circular hole 91 to match with 70 diameter and thickness of phase magnet is got on floor tile with hole making drill；
5) phase magnet 70 is fixed in floor tile circular hole 91 with expansion bolt 73, screw 74, and makes the top surface of phase magnet 70
It is flushed with the top surface of floor tile 90；
Debugging:
1) turn adjusting knob 62 makes the distance of magnet head 41 from the ground less than one centimetre, is greater than three millimeters；
2) door leaf is turned on or off, when the magnet head 41 being mounted on door leaf 80 moves openingly and closingly phase magnet with door leaf
When 70 top, magnet head 41 attracts each other and sticks together with phase magnet 70, at this point, anti-skidding lasso 50 is isolated in the two
Between, the frictional force of anti-skidding lasso 50 can prevent door leaf from continuing to turn on or off；
3) door leaf is firmly moved, when the strength that magnet head 41 and phase magnet 70 attract each other is less than the pulling force of tension spring 45, magnetic
Iron head 41 is raised above, and is no longer rubbed with ground, and door leaf is mobile to restore normal.
The present invention utilizes the performance of magnet, installs phase magnet on ground, both beauty nor affected on walking；It is installed on door leaf
Locator magnet head there is close phase magnet Shi Caihui to be attracted and prevent door leaf mobile, other positions door leaf will not be by fixed
Position device constraint, using more freely；Telescopic head is adjusted upward, can reduce the friction between anti-skidding lasso and phase magnet
Power can also close the positioning function of locator if continue adjusting telescopic head arrives the position that can not be adjusted upwards.
The above embodiment of the present invention is exemplary embodiment cited to illustrate the invention, rather than to of the invention
It is limited made by embodiment.The apparent variation pattern amplified out by the prompt of the embodiment of the present invention is still in of the invention
In rights protection scope.
