Many families can't live without doors, and each door can't live without matching locks. A matching lock can make the function of the door more perfect and have the finishing effect. However, if a door is unlocked, the security cannot be guaranteed. It can be said that the lock is an essential part of the door. As for the door lock, it is divided into door seam lock, channel lock, bathroom lock, etc. according to its purpose, and spherical lock, handle lock, plunger lock, etc. according to its shape. It is divided into door lock, bedroom lock, passage lock, bathroom lock, etc. according to the purpose; According to the shape, it can be divided into ball lock, handle lock, plunger lock, dead lock, etc. The ball lock and handle lock have three functions: lock, handle and touch the ball. The door handle shall be additionally installed for the dead lock.
This requires a good door with a good lock, and what kind of door with a good lock, but do you know how to pick a good lock? Nowadays, in the market, there are many kinds of hardware locks with high similarity in style, which makes many ordinary consumers very headache. So how to choose the hardware lock on the door? The lock expert Fu Shili has come to give you advice. It is important to master the following four points.
1、 Look at the lock material
The locks on the market are basically divided into stainless steel, copper, zinc alloy, aluminum alloy, iron and other materials. These materials have their own advantages and disadvantages.
Stainless steel has high strength, strong corrosion resistance and no discoloration. It is a good lock-making material, but its forging performance is poor. The style and color of stainless steel door locks will be relatively single. The copper material has good mechanical properties. It is generally used to make high-grade European-style door locks. The price and grade are relatively high. Zinc alloy has strong, wear-resistant, corrosion-resistant and other properties, and is relatively easy to cast. It can design many styles and patterns. At present, many of the good locks on the market are made of zinc alloy. However, due to the different proportion and raw materials of zinc alloy and the different design process and casting process, the price difference is very large. The application of aluminum alloy and iron is relatively small. The aluminum alloy is mainly space aluminum. The door lock design of this type is generally relatively simple, without pattern design. The iron door lock is now less and less, and basically belongs to low-end door lock.
2、 Look at the surface treatment of locks
The surface treatment of locks can be divided into three types: electroplating, spraying and coloring. The locks form a dense protective film on the product surface through surface treatment, which plays the role of corrosion prevention and rust prevention, making the locks more beautiful and durable. Dense protective film is also the standard to measure the quality of locks. The locks with good quality are mostly electroplated, and the coating is fine and smooth, uniform and moderate, bright in color, without bubbles, rust and oxidation signs.
3、 Look at the key
There are many types of keys, which are generally divided into flat key (common key and angle key), cross key, computer key
Cylindrical keys, etc. The door lock keys configured with different keys are different. The door locks configured with ordinary flat keys and cross keys are cheaper, but the anti-theft performance is poor. They belong to good door locks. Because the anti-theft performance is relatively low, the public security department vigorously publicizes the use of Class B and Class C locks. The manufacturing process of these two types of locks is relatively high. The more complex the pattern of the key is, the less likely it is to succeed in counterfeiting. If a new key is to be equipped, it must rely on the password card to the designated professional organization, which greatly enhances the anti-theft performance.
4、 Check the implementation standard of locks
Foreign countries have very strict standards and regulations for hardware locks, so the quality of imported products is relatively high. We can feel the quality of the lock with our hands. Generally speaking, the quality of heavy locks is relatively high; The lock body shall not expose its tip, which is easy to hurt people. Pay special attention to the end of the lock handle, the lock tongue and the four corners of the lock body;
The lock with good locking spring can be opened flexibly, with high sensitivity and long service life. There are also many styles of locks, which must be consistent with the style of interior doors.
