The specific embodiment

Do further to specify below in conjunction with accompanying drawing and embodiment the utility model.

Embodiment one:

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of magnetic force door 1 comprises housing 6 and rotor 3, and housing 6 is arranged on underground, and its end face is concordant with ground, and housing 6 middle parts are provided with four adjustment pieces 15, is provided with an adjustment bolt 16 on each adjustment piece 15.Be connected with rotor 3 in the housing 6, rotor 3 bottoms flexibly connect through lower bearing 7 and housing 6 inner bottom surfaces, and rotor 3 tops flexibly connect through the loam cake 2 of upper bearing (metal) 9 with housing 6; Rotor 3 upper ends are flat structure 14; Rotor 3 is connected with door 1 through the flat structure 14 of rotor 3 upper ends, and rotor 3 middle parts are provided with the rotor magnet 4 of two symmetries, and housing 6 inwalls are provided with six housing magnet; Six housing magnet are all corresponding with rotor magnet 4; The first housing magnet, 5 horizontal arrangement, the second housing magnet 10 and the 3rd housing magnet 11 are with respect to the longitudinal axis symmetry of housing 6 end faces, and the first housing magnet 5 is corresponding with the 4th housing magnet 8 positions; Magnetic pole is identical, and opposite with the magnetic pole of rotor magnet 4; The second housing magnet 10 is corresponding with the 5th housing magnet 12 positions, and magnetic pole is identical, and identical with the magnetic pole of rotor magnet 4; The 3rd housing magnet 11 is corresponding with the 6th housing magnet 13 positions; Magnetic pole is identical, and identical with the magnetic pole of rotor magnet 4, and the angle between the first housing magnet 5 and the second housing magnet 10 is 70 °; The angle of the first housing magnet 5 and the 3rd housing magnet 11 is 110 °; Present embodiment rotor magnet 4 is the N utmost point, and the first housing magnet 5 and the 4th housing magnet 8 are the S utmost point, and the second housing magnet 10, the 3rd housing magnet 11, the 5th housing magnet 12 and the 6th housing magnet 13 are the N utmost point.

In the time of need opening the door; The people pushes 1; As long as required thrust overcomes repulsive force and the first housing magnet 5 of the second housing magnet 10, the 3rd housing magnet 11, the 5th housing magnet 12 and 13 pairs of rotor magnets 4 of the 6th housing magnet, the attraction of 8 pairs of rotor magnets 4 of the 4th housing magnet, after door 1 is open between the first housing magnet 5 and the second housing magnet 10, in the time of need closing automatically; Rotor magnet 4 is under the attraction of the first housing magnet 5 and the 4th housing magnet 8; Rotor magnet 4 resets, and returns to horizontal level thereby drive rotor 3, and rotor 3 drives door 1 and is reset to horizontal level; In this process, the repulsive force of the second housing magnet 10, the 3rd housing magnet 11, the 5th housing magnet 12 and 13 pairs of rotor magnets 4 of the 6th housing magnet is converted into the door required thrust that resets; When door 1 was opened between the second housing magnet 10 and the 3rd housing magnet 11, because the second housing magnet 10 and the 3rd housing magnet 11 symmetries, the second housing magnet 10 and the 3rd housing magnet 11 produced repulsive force to rotor magnet 4 respectively; Two mutual balances of repulsive force; In like manner, the also mutual balance of repulsive force that the 5th housing magnet 12 and the 6th housing magnet 13 produce rotor magnet 4 respectively, therefore; It is motionless that rotor 3 keeps between the second housing magnet 10 and the 3rd housing magnet 11; Thereby guarantee that door 1 keeps motionless, when closing, only need to give gently 1 one thrusts of door to get final product like need.

The utility model is in installation process; Need rotor 3 be adjusted to horizontal level; That is, need door 1 be adjusted to closed condition, just the rotor magnet 4 and the first housing magnet 5 and the 4th housing magnet 8 are in the attracted position; At this moment, accomplish the horizontal adjusting of rotors 3 through the adjustment bolt on the adjustment piece 15 of adjustment housing 6 middle parts setting 16.
