Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1 to 4, fig. 1 is a schematic structural view of a magnetic force suction door provided by the present invention; fig. 2 is a schematic structural view of a switch of a magnetic force suction door provided by the present invention; FIG. 3 is a schematic view showing the arrangement of an electromagnet and a strong magnet in the first embodiment; fig. 4 is a schematic view showing the arrangement of the electromagnet and the strong magnet in the second embodiment.
A magnetic force suction door includes: door frame 1, door plant 2, strong magnet 3, electro-magnet 4, switch and crashproof baffle 5.
One side of the door plate 2 is hinged with the door frame 1, and the door plate 2 rotates with the door frame 1 through the hinge to realize the opening and closing of the door. The strong magnet 3 is disposed on the door frame 1, and the strong magnet 3 is preferably disposed on the door frame 1 on a side away from the hinge in view of the lever principle. The electromagnet 4 and the strong magnet 3 are correspondingly arranged on the door panel 2, a coil of the electromagnet 4 is connected with an external power grid through a switch, and the switch controls the electromagnet 4.
Referring to fig. 2, the switch is a double-pole double-throw switch, and includes two moving terminals and four stationary terminals a1, B1, a2 and B2. The movable end is communicated with an external power grid, the end A1 and the end B1 are arranged on the same side, the end A2 and the end B2 are arranged on the other side, the end A1 is communicated with the end B2 and is connected with one end of the coil, and the end A2 is communicated with the end B1 and is connected with the other end of the coil. The circuit design can realize the function of changing the magnetic pole direction of the electromagnet 4 by leading the electromagnet coil to flow in the opposite direction when the A1B1 end is communicated with the A2B2 end. Secondly, because the magnetic pole direction of the strong magnet 3 is kept unchanged, the opening and closing of the door are realized by changing the direction of the magnetic pole of the electromagnet 4 according to the principle that like poles repel and unlike poles attract.
For the door to close more firmly, open more smoothly, just need the big better of the magnetic force between strong magnet 3 and the electro-magnet 4, strong magnet 3 and electro-magnet 4 need just to be arranged promptly. In the first embodiment, the magnetic poles of the strong magnet 3 are arranged towards the door panel, i.e. the strong magnet 3 and the electromagnet 4 are arranged with their magnetic poles facing each other. In the second exemplary embodiment, the poles of the strong magnet 3 are arranged parallel to the door leaf 2, i.e. the strong magnet 3 is arranged parallel to the axis of the electromagnet 4. The two arrangement methods can realize larger magnetic field force and are beneficial to opening and closing the door.
When the electromagnetic switch is closed, the strong magnet 3 and the electromagnet 4 are attracted to each other due to the action of the magnetic field force and finally collide together. In order to protect electromagnet 4 and avoid long-term collision damage to electromagnet 4, door panel 2 is provided with anti-collision baffle 5, and anti-collision baffle 5 is arranged between strong magnet 3 and electromagnet 4 to avoid electromagnet 4 and strong magnet 3 to collide with each other.
Implement the embodiment of the utility model provides a, following beneficial effect has: the magnetic force suction door of the utility model adopts the technical principle that the electromagnet and the strong magnet attract each other, the electromagnet is electrified to generate magnetism, and the electromagnet and the strong magnet attract each other in an opposite way to realize the closing of the door; the current direction of the electromagnet is changed to enable the direction of the magnetic field of the electromagnet to be opposite, the direction of the magnetic field of the strong magnet is kept unchanged, and at the moment, the same poles of the strong magnet and the electromagnet repel each other, so that the door is opened.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
