Tips for identifying the quality of a door lock.

1. Choose a lock for the door.

When choosing a lock, first of all, you should pay attention to choosing a lock that is consistent with the opening direction of your own door, which can make it more convenient to open and close the door; Secondly, pay attention to the width of the door frame, under normal circumstances, the ball lock and handle lock can not be installed on the door less than 90mm, and the width of the skeleton around the door is above 90mm and below 100mm, and the ordinary ball lock 60mm deadbolt should be selected; For more than 100mm, you can choose a lock with a large cover, that is, a 70mm deadbolt; In addition, the thickness of the door is also an important option.

2. Pay attention to the wear resistance of the door lock.

Associated with the wear resistance is the material of the door lock. In the selection of materials, you can use "seeing", "checking" and "listening" to master. Looking at its exterior color, locks made of pure copper are generally polished and frosted, and the color is darker than copper plating, but it is natural.

Weighing its weight, pure copper locks feel heavier, while stainless steel locks are significantly lighter. Listening to the sound of its opening, the sound of the copper-plated lock opening is relatively dull, and the sound of the stainless steel lock is very crisp.

3. Pay attention to the feel of the door lock.

The feel of the door lock is determined by the spring, and the quality of the spring determines the feel and service life when used. If the spring is not good, it is easy to cause the handle to sag and shorten the life of the door lock. When purchasing, you should try the toughness of the door lock spring, the feel brought by a good spring is very soft, not too soft and not too hard.

4. Pay attention to the plating of the lock.

In the process of purchasing, it is also necessary to look at the plating of the door lock, that is, to consider whether the handle of the door lock will fade. Generally speaking, the protective layer, that is, the plating of a good door lock, will not be easily oxidized and worn out. The plating of the door lock handle is related to the overall aesthetics of the room, so this should not be overlooked.

Door hinge purchase.

The door hinges are made of copper and stainless steel. The standard of monolithic hinge area is 10cm 3cm and 10cm 4cm, the diameter of the bottom bracket is between to, and the wall thickness of the hinge is up to 3mm.

The selection of locks is indeed a bit difficult for ordinary consumers.

Generally, when buying a door lock for home use, you first have to look at the materials, and the quality of the locks on the market is uneven, and it is indeed difficult to distinguish.

The first is to look at the material, the general use of thin materials is definitely not good, and then to look at the process, the lock is a hardware product, there are a large number of stamping parts inside and outside, when we look at it, we can observe the tightness of the product assembly, the size of the gap to judge its process. Generally, the larger the gap, the rougher the process, the greater the tolerance of hardware products, and the greater the chance of problems in the use process. Then look at the accessories, the quality and completeness of the accessories is an important indicator to judge whether the brand service is thoughtful.

Finally, look at the key, there are many types of keys, we have to see whether the lock is single-tongue or two-way or multi-directional, look at the keyhole, see what material the lock is made, whether there is a virtual position after the key is inserted, the virtual position is not good, and the rotation is not flexible.

Another point, if it is a cheap ball lock, it is best to take a few more to try, some inferior brand ball locks, the keys can be opened with each other, which is very dangerous.
