The key lock is divided into door locks, channel locks, bathroom locks, etc. according to purpose, and divided into spherical locks, handle locks, mortise locks, etc. according to the shape. According to the purpose, there are door locks, bedroom locks, passage locks, bathroom locks, etc.; according to the shape, there are ball locks, handle locks, mortise locks, and deadlocks.

　　This requires a good door with a good lock, what kind of door with what kind of lock, but do you know how to pick a good lock? Nowadays, there are many kinds of hardware locks on the market, and the styles are highly similar. Many ordinary consumers Very headache. So how to choose a good hardware lock on the door, then follow us to take a look at it in detail. It is very important to master the following four observations.

　　One, look at the lock material

　　The locks on the market are divided into several materials such as stainless steel, copper, zinc alloy, aluminum alloy, and iron. Each of these materials has its advantages and disadvantages.

　　Stainless steel has high strength, strong corrosion-resistance, and does not change color. It is a good lock material, but the forging performance is not good. The style and color of the stainless steel key lock are relatively simple. Copper materials have good mechanical properties and are generally used to make European-style key locks, with relatively high prices and grades. Zinc alloy is strong, wear-resistant, and corrosion-resistant. It is easier to cast. Many styles and patterns can be designed. Many of the better locks on the market are made of zinc alloy. The ratio of zinc alloys and raw materials is different, and the design process is different from the casting process, which causes great price differences. Aluminum and iron are less used. Aluminum alloys are mainly space aluminum. This type of key lock design is generally relatively simple. There is no pattern design. Iron key locks are now less and less, and they are low-end key locks. There are many types of locks. Key locks of different materials and grades are available. It depends on your budget and style. Choose a big brand, and the brand and quality are more guaranteed.

　　2. Look at the surface treatment of the lock

　　The surface treatment of locks can be roughly divided into three types: electroplating, spraying, and coloring. The surface treatment of the locks forms a dense protective film on the surface of the product, which plays the role of anti-corrosion and rust prevention, making the locks more beautiful and durable. The dense protective film is also a measure of the quality of locks. Good-quality locks are mostly electroplated. The coating is fine and smooth, uniform and moderate, with bright color, and no bubbles, rust, and signs of oxidation.

　　Three, look at the key

　　There are many types of keys, generally divided into one-character keys (normal keys and angle keys), cross keys, computer keys,

　　Cylinder keys, etc., the key lock keys of different key configurations are different. The price of the ordinary one-character key and the key lock of the cross key configuration is relatively cheap, but the anti-theft performance is relatively poor, which is a good key lock.

　　Four, look at the lock implementation standards

　　There are very strict standards and regulations for hardware locks abroad, so the quality of the products is relatively high. We can feel the quality of the lock with our hands. Generally speaking, locks that feel heavy are of relatively high quality; the lock body should not be exposed to the tip, which can easily hurt people. Pay attention to the end of the lock handle, the bolt, and the four corners of the lock body;

　　A lock with a good lock spring can be opened flexibly, with high sensitivity and long service life. There are also many styles of locks, so be sure to be consistent with the style of the interior door.
