As far as door locks are concerned, they are divided into door locks, bedroom locks, passage locks, bathroom locks, etc. according to their uses; According to the shape, it can be divided into ball locks, hand locks, mortise locks and dull locks. Ball lock and hand lock have three functions: lock, handle and touch the ball. A door handle should be installed separately for the dead lock.

① door lock: it plays the role of safety, so it is also called safety lock or anti-theft lock.

② access lock: it plays the role of door handle and ball bump, and has no insurance function. It is suitable for locks in kitchens, halls, living rooms, restaurants and children's rooms.

③ bathroom lock: it can be locked inside and unlocked outside the door, which is suitable for bathrooms or bathrooms.

④ bedroom lock: lock the safety inside, and the outside must be opened with a key, which is suitable for bedroom and balcony doors.

2. Choice: Consumers should choose copper-core locks, but it should be noted that some locks are made of plastic, and only a layer of copper-clad "copper-core" locks are wrapped around the core. The appearance of all-copper nickel plating and iron nickel plating is almost the same, but the price difference is very big. Generally, all-copper nickel plating is mute, and iron nickel plating is not mute. If you look closely, all-copper nickel plating is fine and iron nickel plating is rough. If the ball lock is not properly installed when it is installed, it is easy to go wrong in use. Now there is a kind of backhand lock, which can be locked with a slight lift of the handle, which is convenient, but it is easy to lock the key in the house. The more the number of trivial square heads and tongues, the better the safety. Consumers should pay attention to the following points when choosing gadgets. ① The products of enterprises with high quality, stable quality and good after-sales service should be selected.

② firstly, check whether the packaging signs of the purchased products are complete (including the implementation standard, grade, name, address and production date of the products), whether the packaging materials are firm, and whether the contents of the instructions are consistent with the products, so as to prevent exaggeration from being inconsistent with the facts. ③ Observe the appearance quality of the product, including whether the lock head, lock body, lock tongue, handle and cover plate parts and related accessories are complete, whether the surface color of electroplated parts and painted parts is bright and uniform, and whether there are signs of rust, oxidation and damage.

④ to check whether the use function of the product is reliable and flexible, two or more products should be selected for comparison inspection, but when buying a two-way lock product, all keys must be used to try to open and close the internal and external locks respectively. You should also check the insurance institution of the product. It is recommended to try each lock at least three times.

⑤ select accessories according to the use environment, such as humidity, door structure, thickness, left or right door opening, inner or outer door opening, etc.

⑥ mutual opening ratio is the mutual opening ratio of locks and keys. The fewer locks opened by a key, the stronger the safety and reliability of this lock. Consumers should try to choose locks with more teeth when purchasing, because the more teeth there are, the greater the difference, and the lower the mutual opening rate of locks.
