Locks to buy a method to buy a lock in minutes
It is good to Lock the whole family. If you buy a bad lock, every minute is dangerous, so we must pay attention when purchasing. Today, a good home hardware network Xiaobian will tell you how to buy a good lock.
First of all, we must look at the material of the lock. From good to bad, there are copper, stainless steel, zinc alloy, aluminum, iron, etc. The copper lock is the best. It is recommended to buy 304 material for stainless steel and aluminum for aluminum. Don't buy iron locks, because the surface plating will fall off and rust. It will be useless in less than a month.
The second depends on the safety, the most important performance in the lock cylinder, the key and the lock body, the lock core with less marble eyes, it is easy to be opened, a skilled locksmith or thief can be opened in a few seconds with a simple tool. , then we live in it, security and privacy are not guaranteed, and more dangerous! At present, most domestic manufacturers produce such low-end products.
Whether the mutual opening rate of the lock cylinder is acceptable. The mutual opening rate refers to the percentage of the number of times the lock is opened and the number of trial opening. The national industry standard is <0.53%. If the lock core mutual opening rate is high, then the large community is unified by hundreds of households. When the door lock is installed, the keys between the neighbors may open to each other. The door is quite convenient but the safety factor is greatly reduced.
We can distinguish from the key of the tooth flower, the more teeth, the better, the lock core of less than 4 teeth can not buy, the lock body should buy more insurance, double tongue or multiple tongue, buy a single tongue to buy an explosion In this way, the thief is very difficult to open. Not to mention the thief, let us say that if it is a single tongue, it can be opened with an ID card and a bank card, because it has only one oblique tongue, no insurance, but an explosion. The safety of a single slant tongue is much higher.
Third, the smooth and beautiful appearance of the door lock is related to the owner's face, can not be ignored, can pay attention to the following points when purchasing:
1. Whether the surface of the lock body is smooth or not has defects that affect the appearance.
2. Is the key smooth and clean?
3. The key can be inserted into the lock cylinder hole to open the door lock to see if it is smooth and flexible, and whether the force is light and the sound is crisp and sweet.
4. It depends on the degree of labor of the lock. The horizontal static tension of the handle is an important indicator of the firmness of the lock. A high-quality lock, its handle must be guaranteed to switch millions of times and still not straight. This is not a lot of manufacturers can do, often see the switch tens of thousands of times to hang up, but you have to test the individual strength
