Abstract
A magnetic lock is provided. The utility model relates to a lock technology field, which comprises a cathode main body and an anode suction board, wherein, the cathode main body is provided with an electromagnet capable of producing strong magnetic force after energizing, while the size of the anode suction board is matched with the cathode main body. The utility model has the advantages of that the noise of closing the door is little and the door can be opened immediately in case of any fire hazard or accidents, as well as the theft protection performance is quite good.
Description
Affiliated technical field
The utility model relates to a kind of lock, especially a kind of magnetic force lock.
Background technology
At present, known building gate inhibition security door adopts mechanical lock to open the door mostly on the market, the weak point that adopts mechanical lock to open the door be closing noise big, be difficult in time open the door when meeting with fire or accident, theftproof performance is bad.
Summary of the invention
For overcome existing mechanical lock closing noise big, be difficult in time open the door when meeting with fire or accident, the deficiency that theftproof performance is bad, the utility model provides a kind of magnetic force lock, and this magnetic force lock closing noise is little, can in time open the door when meeting with fire or accident, and theftproof performance is good.
The technical scheme that its technical problem that solves the utility model adopts is, a kind of magnetic force lock comprises cathode body, anode suction disc, and the electromagnet that energising can produce strong magnetic force is housed in the cathode body, and the size and the cathode body of anode suction disc are complementary.
On the described anode suction disc steady pin that can be fixed on the door is housed.
There is a circular hole middle part of described anode suction disc, and screw is housed in the circular hole, is rotary with nut on the screw.
The shape of described anode suction disc and cathode body all is cuboids.
The beneficial effects of the utility model are, the cathode body of this magnetic force lock is contained on the doorframe, the anode suction disc is contained on the movable door, automatic device is connected power supply at closing time, the electromagnetic coil energising back that is contained in the cathode body on the doorframe produces magnetic field gravitation, the anode suction disc that will correspondingly with it be contained on the door holds, and door is closed the jail; When opening the door, deenergization, the magnetic field of cathode body disappears, and unclamps suction disc, can open the door.This magnetic force lock can be set to that switch is unblanked or password unlocking or smart card is unblanked or remote-control unlocking, and this lock uses 36 volts or following safe voltage, and is safe in utilization, and have battery can be when cutting off the power supply automatic power.This magnetic force lock can be made different brackets with magnetic force as required, or 10 kilograms or 50 kilograms or 100 kilograms or 280 kilograms or 500 kilograms or 700 kilograms, this magnetic force lock construction is simple, handsome in appearance, easy to use, the noise of closing the door is little, and meeting with fire or accident can in time open the door, and theftproof performance is good.
