Locking and unlocking

——The contest between “spear” and “shield” is difficult to understand The contest between lock and unlock has never stopped. People have tried their best and racked their brains. In the decades-long struggle, the lock as a "shield" has not gained the upper hand for most of the time. The contest between the locksmith and the locksmith is one foot high, and the magic is one foot. This struggle for wisdom has lasted for decades. The "competition" began in the 1950s. At that time, the "iron general" of the door was a padlock. The locksmith only needed to send a small wire to easily get it, but at that time, not many people would come to the door. In the 1970s, the dark locks began to be embedded in the door of thousands of households. But very quickly, the locksmith invented a small hook that reached into the keyhole and gently stirred it twice, and the lock opened. This kind of "technique" was quickly mastered by many people, and even ordinary people themselves could open their own doors with their ID cards. The lock-makers had to find ways to "fall the demon". In the 1980s and 1990s, the cross lock appeared, and the security door came into being. Everyone thought that it could "close the door", but did not expect the locksmith to "go to the next level." They have hundreds of thousands of unlocking tools. The special acetylene bottles are only palm-sized, and all kinds of hooks are available. What's even more amazing is that someone can unlock them with chewing gum. As the eye-point "competition" is constantly upgrading, some lock factories add rare metals to the lock cylinder to deal with chewing gum and master keys . In addition, special-shaped marbles are installed to prevent the opening of the wire hooks, and the key is grooved. I used the computer to enter the password for someone to copy, but I soon heard the rumor: the locksmiths are using "magic" again. Nowadays, some manufacturers who produce locks do not make any progress in the anti-theft performance of their own locks. For commercial purposes, only the appearance of the locks is made a big fuss, changing the shape of the keys, so that the illusion, the consumers, the anti-theft performance of these locks Not even as old as the simple padlock. From the development history of the lock, in order to prevent the opening of the master key, the manufacturing process of the lock will be particularly complicated, the manufacturing cost will increase by a factor of ten, and the performance of the anti-violence damage will be greatly reduced. The industry has been plagued by this problem. So far, what kind of lock to choose to be truly safe is the most concerned thing for consumers.

Other Constructions SS Wire Rope

Wire rope quality judgment:
1. Specific gravity. The diameter of the wire rope is the same, the heavier the specific gravity, the better the quality of the wire rope.
2. Steel wire rope core. The stronger the core of the wire rope, the heavier the specific gravity, the better the support for the outer strand of the wire rope, and the better the quality of the wire rope.
3. Materials. The material is the steel grade and strength. The higher the steel grade, the better the quality of the wire rope with higher strength.
4. After the rope is cut, the slightly loose quality is good, and the quality of the wire rope with a relatively long lay length is better than that with a short lay length.

5. The anti-corrosion ability of 316 Stainless Steel Wire Rope is stronger than that of 306 stainless steel wire rope, and the anti-corrosion ability of 306 is stronger than that of hot-dip galvanized steel wire rope. The quality of hot-dip galvanized steel wire rope is better than that of electro-galvanized steel wire rope; the quality of nylon plastic-Coated Steel Wire Rope is stronger than that of PE plastic-coated steel wire rope.
