For our home locks, this is a necessary equipment for home security, it brings about the safety and convenience issues, we naturally take a little more consideration. However, as the so-called guards cannot be prevented, locking and locking will inevitably usher in uninvited guests. The security of the door once again makes us wrestle with our brains.
A high quality lock What kind of lock is a high quality lock? The most solid and safest! Yes, but what kind of lock is the most secure? Then think about how the thieves deal with your door. The usual method is to use a key substitute to open the door lock, but if your lock cylinder has a maze inside to prevent it from being tight, the thief will certainly not be able to start. He then uses the second trick and hits the lock body. Unfortunately, it is only on the lock body. There is no effort at all, and the thieves are not strong enough to make it. Then try to open the lock, but there is no exposed screw on the outer body of the lock. Do you want to cut off the bolt? In the middle of the bolt, an unusually hard steel was added, and ordinary saw blades did not help at all. The angry uninvited guest had to resort to the last resort—opening the door and forcing it, but the bolt was long. At the same time, there were reinforcements on both sides of the door frame, and the thief was just trying hard. Look, a high-quality lock, at least should have the above conditions.
In addition to traditional mechanical locks, there are electronic locks that are more advanced and save the burden on the keys, but password locks have their own drawbacks - passwords are easy to crack and must be firmly remembered. At present, the most advanced home locks are palm print locks, and your palm print is a portable key. Different room features with different locks to deal with uninvited guests, of course, the lock must not be tolerant, but it must be convenient for their own people.
You must have seen that some locks can be opened with a *** or ID card. Will you use this type of lock? Don't be disgusted with it. In fact, in the home, some rooms should use hardware locks that require less insurance. Bathrooms are among them.
The bathroom may be one of the most dangerous personal hazards in any room in the home. Because of the personal privacy involved, the bathroom door locks should also have a certain degree of insurance. But if this door lock is as unbreakable as the lock of the residential door, it will be a big problem. If someone is in danger in the bathroom, no one can rush in to rescue it in a short time. On the contrary, it is more appropriate to use a lock that is easier to open from outside the room. Bedrooms and children's rooms are also more suitable for this type of lock.
If there is a courtyard in the house, then the door leading to the backyard should also be taken care of. The door should be open from the inside, and from the outside, the key must be used. In addition, storerooms, garages, etc. have door locks suitable for their own use.
