Locks, as the name implies, need to be opened, are loyal guardians, and are also essential commodities in modern home decoration.

With the continuous development of society, people’s requirements for the beauty of decoration are increasing day by day, and people’s requirements for the function, style and appearance of locks have also undergone qualitative changes.

Second, according to the purpose of the lock:
1. Door lock: also called anti-theft lock. The entrance door is the door of every family and the watershed outside the home. It must have a special function, that is, it can play the role of insurance and security. Generally, the entrance door consists of two doors: an iron door and a master door (usually a wooden door). For iron gates, both sides can be locked, commonly known as double-headed lock. Commonly used are multi-safety door locks and mortise steel door locks. It should be noted that the distance between two doors should not be less than 80mm(8 cm). Otherwise, the distance between the two doors (because of the lock handle) is not long enough to be closed at the same time and the anti-theft effect will not be achieved. The wooden door of the main door is generally equipped with a large handle lock, which can play a beautiful role.

Fourth, the matters needing attention in selecting the door lock:
1. Choose a brand with quality assurance. Because brand manufacturers have after-sales service all over the country, they are free to come to the door for maintenance during the warranty period.
2. Door thickness: 35-50 mm for spherical lock. 35-55 mm plug-in. 42 mm mortise lock. 35-55 marble door lock
3. Center distance: the lock should be selected according to the structure of the door. The lock tongue can be divided into 60mm and 70mm. The lock tongue of 70 mm is selected when the door bone width is more than 100mm, and 60 mm is selected when it is less than 100mm and more than 90 mm..
4. Pay attention to the lock that opens in the same direction as your door, because the handle lock is divided into left and right handles.
5. When choosing the handle lock, we should strive to make the handle shape of each functional door lock consistent, so as to make the room more harmonious.
6. Hinge: Care should be taken to choose hinges with sufficient strength to prevent the door from falling for a long time, which will affect the lock opening and even damage it.
Five, how to install the door lock:
1. Pay special attention when installing the spherical door lock. Only the end with insurance can be removed before installation. Never remove the end with key and install it. It is best to read the instructions carefully before installation.
2. Attention should be paid when installing the handle lock: if the left-hand lock and the right-hand lock are interchanged, the handle cannot be lifted up when opening the door, because the middle and high-grade handle locks on the market at present have the function of left-hand switch, and the door opening direction need not be considered when purchasing.
3. When installing the hand lock and the spherical door lock, use the one-to-one installation instructions designed by the original factory.
4. After the door lock is installed, when the door is painted, the door lock must be removed to avoid the exposed parts being stained with paint, because the protective film of the lock will be destroyed when the paint is removed.
5. During the construction period, it is absolutely forbidden to wrap the exposed parts of the lock with adhesive tape (including masking tape) when binding for the protection of the door lock, otherwise the protective film on the surface of the door lock will be damaged after disassembly.
Six, the use and maintenance of door locks:
1. Never drip engine oil into the lock core. If it is not flexible to open it with a key, you can put some pencil lead chips into the keyhole.
2. If the indoor safety of the spherical door lock is inadvertently rotated 900 clockwise, it will become a permanent safety certificate. At this time, it can only be opened with a key, and it can be restored by rotating the safety 900 counterclockwise.
3. In normal use, if there is dirt, it can be removed with a dry cloth (or with a little water), and it is forbidden to scrub with chemicals such as detergent. Otherwise, damage to the protective film of exposed parts will cause fading.
4. When closing the door, it is best to hold the handle, screw the locking bolt into the lock body, and then let go after closing the door. Don’t slam the door hard, otherwise it will reduce the service life of the lock.
Seven, how to identify inferior door locks:
1. First of all, look at whether the surface of the door lock is flat and smooth. Inferior door locks usually have rough surfaces, potholes and obvious flaws, and the surface coating is easy to be leg-colored.
2. Then, carefully check whether the accessories in the door lock package are complete and feel comfortable. Usually, inferior door locks come from small family workshops, and problems will occur in all aspects after a long time.
3. See if the product has passed the inspection of the relevant national quality inspection departments. Usually, all technical indicators of inferior door locks cannot meet the national standards.
Finally, consumers should be warned that when buying locks, they should not buy locks just by looking at the appearance and trying (opening) at the time of purchase, but carefully check and test them many times before buying. If you buy a lock with poor quality and material, it will cause you a lot of trouble, from keeping you indoors to causing damage to life and property. It will bring you convenience and safety to choose a lock with the required function and guaranteed quality correctly.
