With the erection of housing and the appearance of stratification in the society on the property, there was a need to fix at home on the castles, to protect their private property. It is practically no left on the globe of places where people do not use it. For a long time, the device locking the door frame was modified. Manufacturers sought to make constipation reliable, improving its quality. However, the function of the door lock remained the same - it is locking the doors and preserve the htched things. Door constipation put on interior doors.
The main function of the door lock is locking the doors and protection of the house.
Types of door locks
All locking devices in their composition have:
- fixing device;
- Special box for constipation made of metal;
- valve;
- The key to move the beelel.
From what is the design of the door lock, its purpose depends. The method of fastening blocking mechanisms to the doorway divides them to:
- Curling, they are installed inside;
- Overhead are fixed on the inside of the doors.
It is necessary to remember, door invoices and mortise locks are manufactured for "left" and "right-wing" doors, do not advise when establishing them to turn over. This may contribute to their abnormal functioning.
Device of a mortise lock.
There are universal door locks in which the transition from the left to the right door is possible, and vice versa. This can be done if you rearrange the latch or latch. This operation is carried out without disassembly of the entire castle.
A curious type of overhead door lock is a lock-beam. He has two grains. They move across the entire width of the door horizontally. This castle arises to protect the door and from the side where the loops are located.
It is harder to install a mortise view of the door locks, hence the high probability is not particularly high-quality installation. The location of the door canvase, where their insertion occurs, is thoroughly weakened. And its closer location to the outer surface makes the door more accessible hacker. We must pay tribute to mortise locks that are less visible and more convenient to use.

Overhead door locks do not have such shortcomings as mortise. Install them elementary, in places of installation they do not lower the fortress. Overhead locks are perfectly functioning on the doors that open inside. This type of door lock perfectly protects against the attempts from the outside, but a hacker located in the room, it is not a hindrance. Overhead locks have a disadvantage - this is a change in the appearance of doors for the worse.

Door locks with multiple downes are manufactured now. They are called multi-surge castles. A reliable shut-off system of that deposits (riglels) of which is distributed across as much as possible the length of the door.
The most famous mechanism of the door lock is mortise constipation. It includes:
- housing;
- facial plank detail;
- drive lever;
- Casov with basic action;
- Casov with a special latch.
Regardless, what is the fastening to the doors, the adaptation of the current closing mechanisms contains two components:
- the secret, with his help finds the key to the castle;
- The actuator performs locking.
Varieties of secrets
Mechanical secrets are manufactured in various versions:- In the form of a cylinder. The basis is a special detail - the cylinder. In his middle there are pins - elements that interfere with the hacking of the castle. Such a castle is called English. He is most common.
- Code. Opened when the key is introduced as a set of desired numbers.
- Suwald. Finding multiple teeth on the key defining the number of Suwald.
- Electronic. Created on a drive embedded inside.
Types of executive devices
Cylinder type lock: 1 - cylinder case, 2 - cylinder (core) with code mechanism, 3 - well for key, 4 - code pins (pins), 5 - locking pins (pins), 6 - leash / cam, 7 - Fastening hole, 8 - spring, 9 - key, 10 - separation line between the case and cylinder.
There are several systems that are used as an actuator. It:
- mechanical when the closure is performed by a metal rod, which is included in a special groove;
- electromechanical, here there are changes in electrical drive;
- Electromagnetic, shut-off mechanism is a magnet.

The reliability of the locking system of the Suwald door lock depends on the number of plates. Their greater amount contributes to more reliable protection of the room.
The system of this type of lock consists of the following elements:
- Rigel, this is the transverse mechanism of gravity;
- Suwald - metal plate;
- Specially designed key for the key.
This system operates on the principle of classes by all plates of the established positions, only in this case can be done turning the key. Plates are placed under the influence of the keys in well-appointed positions. It permits to rotate the key and the mechanism of the door lock. But if at least one of the plates does not turn out to be in its intended groove, then all the device will not work. That is, the key is the lock code.
Such door locks are quite difficult to open the force of force. Suwald door locks have a long service life and a high degree of reliability. The advantages include their high secrecy and simplicity of design. Under all the rules of assembly and safety standards, such a castle is difficult to hack.
Structure of the cylinder lock system

The cylinder locking mechanism is overhead and mortise. It has a secret device in the middle. Such door locks are manufactured:
- one-sided, they open the key only on the one hand;
- Bilateral, these locks have two cylinders and on the inside are not open without a key.
In order to close the housing with such a lock, you need to perform certain actions: the key is inserted into the hole that has a limited protrusion. This hole is in the cylinder, the part of which is always spinning, but this will happen in the case when the proper key is inserted. The rest of the device will remain real estate - this is a housing. Executive adaptation are pins. They serve to raise the key. From what their position will depend on, constipation is open or closed.
The door lock will open only with full combination of all coded elements.

In some cases, it is required to close the door between the rooms, and then stop your choice on a special built-in door in the door. It includes:
- swivel plate;
- gate;

- lever for hold;
- latch;
- case cover.
People over the years have developed a habit by leaving the house, close it on special door locks. Once they were very simple. Nowadays, the use of computer technology has led to the appearance of invisible locks. They perfectly cope with the task of ensuring the protection of housing from hacking. If the door locks are simple and inexpensive, then it is not possible to drill them and knock them out. The locking design hidden in the door acts solely from the radio frequencies of a special keyfob.
From this we can conclude that the best way out will purchase one high-quality constipation. You can connect different types of door locks in one stop system, it will complicate the work of hackers. It must be remembered that when choosing, you need to scrupulously examine such a design for all sorts of flaps so that it does not fail at the right moment.
