How to choose mechanical lock?
1.Check the material
There are many kinds of door locks on the market, but they are basically divided into stainless steel, copper, zinc alloy, aluminum alloy and iron. These materials can't tell who is better, but they have their own advantages and disadvantages.
Stainless steel lock is corrosion-resistant and not easy to change color. But the casting performance is poor. But stainless steel is a good material for locks.
The price and grade of copper lock is relatively high, and they are most commonly used in European style door.
Zinc alloy lock is easy to cast, with good corrosion resistance, firmness and wear resistance. China zinc alloy lock is relatively popular in the market. However, due to the different design and casting process of zinc alloy, the price is relatively large in same material.
Iron door lock is rare now, and iron is easy to rust.
In short, there are many kinds of locks in the market，different materials and style are different price. As for what kind of locks to choose, we should still choose according to our own needs.
2、Check the surface treatment of lock
The surface treatment of the lock can be roughly divided into three ways: spraying, electroplating and coloring. The purpose is to form a protective film on the surface of the lock, so that the lock can play the role of anti-corrosion and rust prevention, and make the service life of the lock longer and more durable. The protective film on the surface of the lock can also be used as one of the standards to judge the quality of the lock. The vast majority of locks with good quality use electroplating treatment, because the surface texture of electroplating treatment is more delicate and shiny, without bubbles, rust and oxidation.
3、Check the key
Whether the lock is safe or not, the more important thing is the key. Key has Yale, Kwikset and Schlage. The low-cost door lock has poor anti-theft performance, which can be easily opened. Therefore, the public security department publicizes that we should use class B and class C locks.Because the patterns on the key surface is complex and not easy to imitate, which greatly improves the anti-theft performance.
4、 Whether the lock meets the national standard
The market is full of a large number of door locks that do not meet the standards. If the safety performance does not meet the standards, its anti-theft performance is also worrying. Good quality lock is heavier than poor quality; In addition, we should pay attention to the spring of the lock. Good spring has highly sensitive and flexible to open and lock the door.
How to maintain the mechanical lock
1. Avoid excessive vibration
When closing the door at ordinary times, try to avoid pushing the door vigorously. Although the door lock is shockproof, when the external impact force is strong, it is easy to loosen or even dislocation the internal rotating connection part of the lock.
2. Try to avoid dirty hands
When you touch the door lock, try to avoid dirty hands. Although the surface technology of many door locks is very good and its anti-corrosion and rust resistance is very strong, the dirt stuck during contact will also penetrate into the interior of the lock through the gap. Over time, the lock is easy to get old.
3. Wipe the door lock surface regularly
After using for a period of time, the lock will inevitably fall dirt. At this time, wipe the surface of the lock with a dry soft cotton towel. It is recommended to clean it once a quarter or half a year.
4. Do not use lubricants casually
When the lock cylinder is astringent or tight, you can cut some broken pencils or candles, blow them into the lock cylinder through a thin tube, and then insert the key and rotate it several times. Remember not to use lubricating oil casually. The oil is easy to stick to dust. In the future, it will be easy to slowly accumulate dust in the keyhole and form oil putty, which will make the door lock more prone to failure.
5. Tighten loose locks in time
When the lock is loose, use tools to tighten the exposed part in time, otherwise it is easy to cause damage to the mechanical structure and affect the service life.
