Insert the key into the keyhole and unlock it without turning. Have you seen such a lock? Peng Liang, a 58-year-old resident of the Shiyun Guiyuan Community in Dashiba, Jiangbei District, has painstakingly studied and designed two locks that claim to be unbreakable. The two locks were transformed by Zhou Yong, a 27-year-old locksmith. One of the locks obtained the national patent and the other passed the preliminary examination of the State Intellectual Property Office.
Yesterday, Peng Liangxuan and Zhou Yong told the Chongqing Evening News reporter: "We want to send a challenge book to the heroes through the Chongqing Evening News: Hanging red 10,000 yuan to collect the unlockers."
Chongqing Evening News reporter experience
Two locks have their own
Yesterday morning, the Chongqing Evening News reporter came to the lock shop of Zhou Yong, No. 2, No. 156, Jianxin West Road, Jiangbei District. The two locks are different from the outside: one consists of a knob and a small keyhole, the key can be turned on without turning it; the other consists of a knob and a password disk, and the number of passwords is 8 . Peng Lianghao said: "Chongqing and even the Chinese market, no one has seen these two locks."
Chongqing Evening News reporter tried the first lock: put the key into the keyhole, the key just occupied the keyhole space, can not turn left and right, and then gently turn the knob above the keyhole, the lock is turned on.
The second lock, first turn the password disk, then turn the knob left and right, in an instant, the password disk is stuck.
The inventor is a Changan employee
Inspired by a news
Peng Liangxiao said with a smile that it was a news that he had been dealing with machinery for a lifetime and driving him to study the lock. “In 1995, I did mechanical design at Changan Co., Ltd. One day I saw a news saying that there were more than 40 vehicles in a city that were stolen at the same time. I thought: Can you invent a safe, reliable and easy to use? The lock?" With this in mind, Peng Liangxi began to look for information and self-learning design locks.
In 2010 and 2012, Peng Liangqi designed the self-locking code disc type anti-theft lock and high-density car alarm to obtain the national patent, but he is not satisfied: "The operation is difficult, not suitable for marketing."
In July of this year, Peng Liangxi spent two months designing a combination mechanical lock. Peng Liangzhen is full of confidence in the market prospect of this lock: "As long as someone is willing to put into production, I believe there will be a larger market."
Career unlocker evaluation
Both locks are amazing
"I have been a locksmith for nearly 30 years. I have never seen such a lock. It is indeed the top lock in the lock." The 66-year-old professional unlocker, Chang Changlun, said that judging the quality of a lock depends on the finished product. These two locks are only samples, so it is not possible to estimate the safety performance after they are put into production. “The materials used in the lock itself and the materials used in the doors are important.†Yan Changlun said that these are all factors that determine the quality of the lock.
"Technically speaking, both locks are remarkable inventions." Yan Changlun said that the general unlocking tools can't open them. From the practical point of view, especially the combination of mechanical locks, easy for ordinary citizens to use, has a great market prospect.
Coreless lock password is the key
Peng Liangxi first introduced the lock that does not turn the key: this lock is a combination of the mechanical code lock and the blade lock. The key is equivalent to the password—the key is inserted into the keyhole, and the key is matched with the shape in the keyhole. Turn the knob to unlock it.
"The common household lock on the market is to turn the lock and lock. There is a lock cylinder. After the key is inserted, the lock core drives the transmission structure to unlock. This lock saves this step and is very convenient." Peng Liangxi said, pure mechanical password. Lock, you need to code, you need to remember the password, once you forget the password or the code is not accurate, it is difficult to open.
"The operation of this lock is simple, but without the key in my hand, it is impossible to open it." Zhou Yong said that this combination mechanical lock is embedded in the center of the door, anti-drilling, anti-smashing, anti-twist, anti-tin foil, Also prevent technology. Zhou Yong said: "To open this lock, first of all, the key data will be taken one by one, and the spare key will be used to install the truck."
Zhou Yong explained that it is unrealistic to open the lock with the traditional twisting method. The reason is that the key does not have the turning function, and the lock is embedded in the door. To twist the lock, the door must be drilled first. If the lock is forcibly twisted, the structure inside the lock will be broken and the lock will not be unlocked.
8-digit password lock required to open 63 years
After introducing the first lock, Zhou Yong picked up the combination lock next to the combination mechanical lock, and then picked up a common password lock and said: "This password lock can be used in safes, ATM cash machines. Now the most powerful ATM withdrawals on the market. The machine is a 4-digit password, and this lock is 8 digits."
Zhou Yong said that there are theoretically 500,000 sets of 4-digit combination locks, and ATM locks on the market usually only have 400,000 sets of passwords, and this 8-digit combination lock has 50 million combinations. Zhou Yong explained that the password lock has an 8-digit password, and the user can set a password of 3 to 8 digits as needed. Suppose the user sets an 8-digit password (such as 10, 20, 30, 40), and the password combination data is 50 million. A total of 40 seconds to align a set of passwords, all the passwords must be tried, and the worst case will take 63 years.
This combination lock also has an advantage - the unlock knob next to it. "The password lock has a self-locking function. If the password is incorrect, the password disk will be automatically locked for 30 seconds, which increases the opening time. Therefore, this lock is an upgraded version of the ordinary insurance lock and ATM lock. The difficulty of opening it is the general lock. 100 times."
Zhou Yong explained that the password lock will break if it is lightly clicked, and the lock is broken. Only the cutter can be used to cut the door. The technical password is to be carried out by hand, hearing and calculation. This password lock has no feel. To open it, only one password is required.
