Analysis of the characteristics of furniture locks:

There are many types of locks on the market today. As far as door locks are concerned, they are divided into door locks, bedroom locks, passage locks, bathroom locks, etc. according to their uses; ball locks, handle locks, mortise locks, dead locks, etc. according to their shapes. Ball locks and handle locks have three functions: lock, handle and hit the ball. Deadlocks require additional door handles.


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


②Access lock: It acts as a door handle and bumper, and has no insurance function. It is suitable for door locks in kitchens, halls, living rooms, dining rooms and children's rooms.


③ Bathroom lock: The feature is that it can be locked inside and can be opened with a key outside the door, suitable for toilets or bathrooms.


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


The materials used for locks are mainly copper, stainless steel, zinc alloy, steel, aluminum or aluminum alloy.

①Copper: It is one of the most widely used lock materials, with good mechanical properties, good corrosion resistance and processing performance, and bright color, especially for copper forged handles and other lock decorative parts, with a smooth surface, good density, and no pores. , trachoma.


②Stainless steel: durable, the more you use it, the brighter it becomes. It has good strength, strong corrosion resistance and unchanged color.


③ Zinc alloy material: its strength and rust resistance are poor, and the advantage is that it is easy to make parts with complex patterns, especially pressure casting. The locks with more complex patterns seen on the market are mostly zinc alloys.


④Steel: Good strength and low cost. Generally, a coating is added, but it is easy to rust.


⑤ Aluminum or aluminum alloy: ordinary aluminum alloy (except for aerospace) is soft and light, and the material strength is relatively low, but it is easy to be processed and formed.


how to choose

Consumers should choose copper cores, but it should be noted that some of the cores are plastic, and only a "copper core" with a layer of copper skin is wrapped around the core head. The appearance of all-copper nickel-plated and iron-plated nickel-plated is almost the same, but the price is very different. Generally, all copper-plated with mute, iron without mute, look closely at the fine workmanship of all-copper and iron. When the ball type is installed, such as the eccentric core, etc. are not installed properly, it is very easy to go wrong in use. Now there is a kind of backhand lock, which can be locked by lightly lifting the handle, which is very convenient, but it is easy to lock the key in the house.


Now, the fastest selling is the handle lock, the ball lock is outdated and generally not used. Relatively speaking, when turning the trivial tool, the smaller the sound, the better. If the handle is turned a little, the trivial tongue should follow up. In terms of key shape, the "pit"-shaped key accessory is more secure than the "tooth"-shaped key accessory, but if the "pit"-shaped key is lost, it must be matched by the original factory. The greater the number of square tongues of the trivet, the better the safety. Consumers should pay attention to the following points when choosing accessories.

① The products of enterprises with high reputation, stable quality and good after-sales service should be selected.


② First check whether the signs of the purchased product packaging are complete (including the product's implementation standard, grade, manufacturer's name, address, and production date), whether the packaging is firm, whether the content of the instruction manual is consistent with the product, and beware of exaggeration and inconsistency with the facts. Phenomenon.


③ Observe the appearance and 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, whether there is any sign of rust, oxidation, etc. damaged.


④ To check whether the use function of the product is reliable and flexible, more than two products should be selected for comparative inspection, especially when purchasing two-way lock products, all keys must be used to test the inner and outer locks respectively. You should also check the insurance agency of the product, and it is recommended to try each lock at least three times.


⑤Choose trivial tools according to the use environment, such as dry humidity, door structure, thickness, left door or right door, inner door or outer door, etc.


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