Thanks to combination protection algorithms, the functions of all protective products can be improved. Their ergonomics are liked by many buyers. All mechanical systems are top notch. A similar concept is often used in special devices for machine safety. At the same time, conventional anti-theft systems are supplemented by control modules. Often, such devices are used to protect private buildings. The combination lock on the door can be found in every city in any country.
How does the locking system work? Its mechanical control is controlled by a panel set. Due to this, the operation of the device will be convenient and as safe as possible. However, such devices have their drawbacks. Which ones?
In the article, we consider the general characteristics of the devices. How is the installation completed, how to change the code combination, as well as which model is considered the best?
Mechanism device
Mechanical combination locks, the price of which is quite adequate, have the simplest design. It consists of components that operate under the influence of electronics. The basis is latches, springs, levers, clip and pins. In the market you can also find other solutions - non-standard models. You need to know what the differences are between electronic and mechanical products. What is their difference? It lies in the fact that the former have special combinations in the controller. And mechanical options store the required sequence in the form of the correct location of the above parts. When a person presses a button, a shift occurs, and the latch releases the clip.
Varieties of models
A mechanical combination lock is often installed on the door. In this case, it is necessary to distinguish between the invoice and the hinged type. Mortise systems maximize the reliability of the structure. The nodes of the described castle will work together and harmoniously. Thanks to the design, the mechanism can be installed in the door, respectively, the gap is completely excluded. The lock panel will remain on the front side. It is on it that data is entered - the code.
However, there are those models that received a different installation method. This situation is inherent in mechanisms with an overhead type. Often use similar systems in those cases when the mortise installation method is simply not possible. For example, often according to this scheme, the lock is mounted on the gate. In such cases, the mechanical unit and all its components are on the street. Therefore, the security level will be lower. However, there is an advantage - installation work is as easy as possible. After all, a mechanical combination lock on the door will be much easier to install.
As mentioned above, there are mounted models. They are mobile and do not need to be installed. Constipation is any chain or loop. The main thing is that they are strong and reliable.
Installation work
Before you begin to install a mechanical combination lock, you must outline the fixation point. How it's done? On the canvas, you need to make a selection with grooves, and in the niche make room for the location of the latches. In order to cut wood, it is better to use model saws (jigsaws) on the battery or wired options. Then the installation process of the lock will be easy. Thanks to this solution, the opening can be more accurate.
It remains to establish the lock and the bar of constipation. The last place should be marked on the box. The correct dimensions must be observed. Between the plank and the end of the castle itself should be no more than 5 mm. What should be the value for a particular model can be found in the instructions for it. After installing the mechanical combination lock, you need to check its performance. First, this is done with the door open, then closed. If the latch correctly and easily enters the niche and easily exits, then the installation is carried out correctly. When buying a mechanical combination lock, instructions are included. Therefore, all the details of the installation can be learned from it.
Recommendations for use
When working with combination locks, you need to maintain their working condition, constantly monitor them. Why is this so important? The fact is that ordinary level and cylindrical systems do not have such a delicate work of all elements. An ordinary consumer will be able to maintain the lock in working condition with grease. There are also special tools. They are used to handle clips and bolts. If you do not have the desire or ability to use such funds, then you can use ordinary engine oil. If you follow this rule, then the castle will be able to last a long period without any failures and repairs.
Even with the fact that all models should be serviced differently, they all have a common configuration and, accordingly, uniform recommendations. For example, it is not worth opening the door while typing.
Install and change code
A combination can have multiple characters. Their number depends on the model of the castle. Typically, a code contains 3 or more characters. In order to change it, you need to remove the screws and the spring block, lever. The coding is done by changing the level parts in the structure itself. That is how all secrecy is achieved.
Summary
The most popular is the Mettem mechanical combination lock. It does not break down in the process of work, is able to serve for a long time, and also allows to ensure the safety of residents of an apartment or house. On the Internet you can read a lot of reviews about such a device. They are all positive.
The price of a mechanical combination lock starts from 4 thousand rubles. For the money you can buy quality goods.
