Lock worries

According to the definition of the Dictionary, "a gag that can only be opened with a key is called a lock"; in other words, if it can be opened and closed without a key it can't be called a lock, or at least it can't be called a lock worthy of the name. Modern locks have been developed for more than a hundred years, and people have studied its structure and mechanism thoroughly, so there are numerous methods and tools that can be opened without a key. Modern human civilization, due to various conflicts in society is very intense, people's ideological and moral concepts, values, cultural cultivation level and other differences in the masses of good and bad, good people can consciously regulate their own behavior, "not a gift", although no key will not break in. However, those who have no moral concept of thieves are trying to find ways to use high-tech means to pick the door unlocked, so that the majority of residents can not be defended. Why is this situation? Because the traditional locks have fatal weaknesses: First, the lock core using common copper, aluminum, zinc and other materials, can not resist strong damage; Second, the lock production process, technology is backward, can not prevent the opening of technical means. At present, many domestic and foreign locks on the market, in fact, do not have a real anti-theft function. In front of the habitual thief, two steel wire or a few simple tools can open these locks, some habitual thieves even openly threatened: "No I can not open the lock." In fact, it is not how smart they are, but the general lock technology principle is too simple. In the face of this cruel status quo, the new era puts forward the locks must revolutionize the urgent requirements.

Lock making and unlocking

--"Spear" and "shield" of the competition is difficult to distinguish between locks and unlocking of the competition has never stopped, people go to great lengths. Wracked brains, in the decades of struggle, as a "shield" of the lock, in most of the time has not prevailed. Locksmiths and locksmiths of the competition is the Taoist high feet, the devil is high, this wisdom of the struggle has lasted for decades. "Competition" began in the 1950s, when the door of the "Iron General" is padlock, locksmiths only need to move a small wire, it will be easy to get, but then there are not many people will come to move the door of the mind.

By the 1970s, concealed locks began to be embedded in the doors of thousands of homes. But soon, locksmiths invented a small hook that went into the lock hole and gently stirred the lock open. This "technology" was soon mastered by many people, even the ordinary people themselves with ID cards can open their own doors very casually. Lock makers had to find ways to "subdue the devil". In the eighties and nineties, cross locks appeared, security doors also came into being, everyone thought that you can "close the door", but did not think that locksmiths have also been "a higher level". Their locksmith tools up to hundreds of thousands of special acetylene bottles only the size of a palm, a variety of shapes of hooks are available, more magical is that some people with chewing gum can open the lock. With an eye on the "contest" in the continuous upgrading, some lock factory in the lock core to add rare metals, specifically against chewing gum and master key; in addition, also loaded with shaped bullets, to prevent the opening of the wire hooks, the key on the use of the word groove-shaped, computer-entered code in case someone copy, but soon heard rumors: locksmiths again in the performance of the "magic". Today, some manufacturers of locks in their own locks on the anti-theft performance, there is no progress, for commercial purposes, only in the appearance of the locks to make a big deal, change the shape of the key, make a fuss, the consumer, these locks are not even as good as the oldest, simple padlocks on the anti-theft performance. From the history of the development of locks, in order to prevent the opening of the master key, the lock manufacturing process will be particularly complex, the manufacturing cost will be increased tenfold, at the same time, the performance of its anti-violence damage will be greatly reduced, the lock manufacturing industry has been plagued by this problem. So far, the choice of what kind of locks can be truly safe is the most concerned about the majority of consumers.
