Abstract
The utility model provides a magnetic security door, which consists of a movable door and a magnetic absorption device arranged on a door frame. The magnetic absorption device consists of a rotatable cylindrical magnet and two magnetic shells. The cylindrical magnet is fixedly provided with a worm wheel coaxially. The worm wheel is meshed with a hand-held worm. The hand-held worm is fixedly connected with a handle. The worm wheel is meshed with the worm of a motor. A motor shaft is fixedly connected with the worm of the motor. By adopting a remote manipulator for controlling the rotation of the motor, the movable door is tightly absorbed with the door frame through the magnetic force generated from the rotation of the cylindrical magnet driven by the worm wheel and the worm. After a thief pries the bolt of the security door, the security is difficult to be pried due to the magnetic force between the movable door and the door frame. Once a pry bar becomes loose, the security door is absorbed back. The magnetic security door eliminates the defect that the bolt of the security door is pried open by thieves easily.

Summary of the invention
The purpose of this utility model provides a kind of magnetic security door, is used to strengthen the anti-theft effect of security door.
Technical solution adopted in the utility model is: the magnetic security door, by dodge gate and doorframe the magnetic force door closer-holder being set forms, it is characterized in that doorframe is equipped with magnetic inductive block, dodge gate is equipped with the magnetic force locking device, the magnetic force locking device is made of rotating cylindrical magnet and two magnetic conductive shells, in two magnetic conductive shells columniform die cavity is arranged, rotating cylindrical magnet is connected movingly with the interior die cavity of two magnetic conductive shells, separate by magnetic conduction lath not in the middle of two magnetic conductive shells, the cylindrical magnet rotating shaft is installed on the bearing support of dodge gate movingly, the coaxial worm gear that is fixed with of cylindrical magnet, worm gear with hold worm engaging, hold worm screw and fixedly connected with holding, worm gear and motor worm engagement, motor shaft is fixedlyed connected with motor worm.
Use at closing time, utilize remote controller control motor to rotate, drive cylindrical magnet by worm and gear and rotate counterclockwise 90 ° of angles, make the S utmost point on the left side of the cylindrical magnet of cylindrical magnet, the N utmost point of cylindrical magnet on the right, because the S utmost point of cylindrical magnet is by two magnetic conductive shells and the magnetic inductive block of doorframe and the N utmost point formation magnetic loop of cylindrical magnet, generation magnetic force sucks two magnetic conductive shells of dodge gate and the magnetic inductive block of doorframe.After the thief pried open the bolt of security door, because dodge gate and doorframe have magnetic force to suck, security door was not still opened.
When opening the door, utilize remote controller control driven by motor cylindrical magnet to clockwise rotate 90 ° of angles, the S utmost point that makes cylindrical magnet in front, the N utmost point of cylindrical magnet in the back, the magnetic line of force of cylindrical magnet is formed the magnetic loop of inside by the S utmost point of two magnetic conductive shells and cylindrical magnet by the N utmost point of cylindrical magnet, make the magnetic flux that is installed on the magnetic inductive block in the doorframe reduce to zero, the suction of magnetic inductive block and two magnetic conductive shells is eliminated, and security door can be opened.Also can hold slewing circle cylindricality magnet in indoor utilization and clockwise rotate 90 ° of angles, make the magnetic flux that is installed on the magnetic inductive block in the doorframe reduce to zero, the suction of magnetic inductive block and two magnetic conductive shells is eliminated, and opens security door.
The beneficial effects of the utility model are: under the situation that the bolt of security door is pried open, magnetic force can not eliminated, do cylindrical magnet as long as select the permanent magnet of high magnetic flux, will make security door be difficult to pry open, in case crow bar unclamps, security door also can be sucked back again, solves the defective that the security door bolt is pried open by the thief easily.
