Magnetic locks have recently gained a lot of popularity, even entered the market of home security systems recently.No wonder that the demand for locks of this type increases with time, because it is a modern kind of equipment that is superior to conventional, traditional locks are not only aesthetically, but also in terms of ease of use: they are easily interchangeable, easy to use, but the most important anda nice touch is that they are absolutely silent.What provides a collection of all these benefits?In the first place, of course, the design of the magnetic lock.A distinctive feature of its mechanism of action is that it does not contain the core, through which ordinary locked door.From the name of the castle it is clear that this device is locking the door, based on the principles of magnetic interaction between the particles.Well, just entertaining physics at home!
mechanism of action
make it easier to understand the mechanism of action of interior magnetic locks, let's look at the most primitive of these, which is called "passive" because of its ease of use.It consists of a pair of components: a magnet and a metal layer.The magnet is located in the castle, and the metal layer - in the door leaf.That is, when the door is closed, the magnet attracts the metal layer, thereby keeping the door in this position indefinitely until it is willing to open.In order to open a door, you must attach a mechanical force."Passive locks" hardly installed in the door, often inserted into the doors of cabinets and dressers.As for internal doors, they are distinguished by the presence of the handle.It is much easier to use them, because the effort is no longer necessary.When you try to open the door handle is rotated, the magnet is located in the castle, and metal lath change their position relative to each other.After that, the door is now closed and no longer in the room can be easily and naturally enter.
When the magnetic lock can not cope
If you want to close the door firmly, so that one turn of the handle to open it did not have enough suitable electromagnetic locks.The device such locks more difficult as the work involved is an electromagnetic field.On the lock is always applied to a powerful electric power, therefore as soon as the lack of a regular supply of electricity, the doors are unlocked and do not provide the safety and security of property.Of course, the task is much easier those locks, which are a part of their design an extra battery or battery.The battery will some time in the absence of electricity to keep the door closed.The two major components of an electromagnetic lock plate is made of metal, as in the simple magnetic closure and an electromagnet.The magnet is inserted into a doorframe.The electromagnetic field generated by applying electricity to the magnet attracts the plate.After that, the doors are closed.The doors open with the help of an additional device.Typically, such a device acts as a button.Manufacturers electromagnetic locks a lot, so depending on the model, the locks have different capacity.Doors with electromagnetic locks capable of withstanding a load of one hundred kilograms to tons.
