Two big tricks teach you how to choose a safety lock

For those who pay attention to details, the door is a more important part of the decoration. Because the door is not only connected with the beauty of the living room, but also related to important issues such as the safety and privacy of the home. Therefore, the door is like a general in a room or a suite, guarding a private space that no one can visit at will.

How can I choose a safety lock? The following points should be noted.

1. Look at the handle: We can see such a spherical handle on many occasions. It looks good, but is it really safe? Imagine that you need to escape immediately if there is a fire in the room, and your hands are injured. Shangli, how to open this spherical handle?

After opening the lock cylinder with the key, you must rely on the handle on the lock to open the door. Choosing a safe handle mainly depends on its shape and resilience.

The really safe one should be this long handle. Under extreme conditions, even if you don't use your hands, you can easily open the door with your elbows, shoulders, and even your head. Of course, when choosing a lock, you should not just look at the shape, but also press the handle repeatedly to try the feel. Only with strong resilience and accurate resetting of the handle can the door be opened quickly at any moment.

2. Look at the key: The traditional key is single-sided or double-sided, with a combination of pits and slots. All the pits or slots on the key are on the same plane, with the same shape, size, and depth. The lock core corresponding to this key also relies on 1 to 2 rows of flat marbles to achieve the anti-theft function. A skilled locksmith only needs a tool and ten seconds to open such a lock, and its safety is really worrying. .

The locks in the mall cannot be disassembled to see. In fact, as long as you carefully observe the distribution of the slots and pits on the keys, you can determine whether the corresponding locks are safe.

The surface of the safe key is distributed with pits of different shapes, sizes, and depths. Different from traditional keys, these pits are distributed around the entire key, and the corresponding lock cylinder is secured by multiple rows of marbles with different sizes and heights in the three-dimensional direction. This kind of lock does not rely on a key, and basically only has a theoretical opening possibility.

For the choice of material, look at its appearance and color. The locks made of pure copper are generally polished and frosted. Compared with the copper plating, the color is darker, but it is very natural. Considering its weight, pure copper locks feel heavier, while stainless steel locks are significantly lighter. Listening to the opening sound, the opening sound of the copper-plated lock is rather dull, and the sound of the stainless steel lock is very crisp.
