With the creation path of "can't go", Locke Wu Qiliang has developed a mechanical anti-theft lock for 3 years.

Wu Qiliang showed various locks.

"It can break when you can break it." "It can break when it can stand." Lockers and locksmiths are like spears and shields, and they are driving the development of an industry in constant darkness. In order to verify whether the mechanical anti-theft lock developed by the company has reliable safety performance, Wu Qiliang, general manager of Ningbo Shenzhou Lock Industry Co., Ltd., was rushed to Beijing to open a “challenge” to Cao Qingmin, secretary general of the China Locksmith Club. Five minutes passed, and this small civilian lock made it difficult for the senior locksmith who could open 30 ATMs in the Wenchuan earthquake. After 15 hours, after studying the manufacturing principle and structure of the lock all night, Cao Qingmin still could not open.

This dramatic scene was recorded in the "Witness" column, which was broadcast on CCTV 12 on September 2 last year and July 28 this year. "According to national security standards, civilian anti-theft locks are divided into three levels: A, B, and Super B. The violent opening time of Class A is within one minute, the B level is between 1 and 5 minutes, and the Super B level must be more than 5 minutes. Wu Qiliang is still very excited when he talks about this move, but he always believes that the locksmith is a good teacher and friend of structural design, and is the testing authority for the quality of locks.

Laowu has been locked for dozens of years, and all of them are military locks, because he feels that the civilian lock is too simple and not challenging. In 2009, the number of cases of burglary using tin foil keys across the country increased dramatically, seriously affecting social security. After learning about this situation, Lao Wu decided to use his military lock technology to develop a high-quality civilian lock that restrains tin foil keys.

After spending three years designing, Lao Wu did not dare to mass-produce, because he was worried that this latch was in the design loophole and would be easily opened by the unlocking master. So I put down the downfall in Ningbo, let the masters of the road unlocked and tried to open it. After three days, no one could open. Lao Wu told the reporter that although the lock passed the test of the Ministry of Public Security and obtained the "China Security Technology Prevention" certification, he still did not trust, so he had the story of going to Beijing to ask Cao Qingmin to open the test.

Wu Qiliang joked that his company is the Folk Lock Institute. In the general manager's office on the second floor of Shenzhou Lock, two desks in the 1990s were filled with locks, lock cylinders, locks and various kinds of Unlocking tools, he told reporters that to use the locksmith's thinking to design high-performance locks, only the social benefits can be improved to produce economic benefits.

In March and May of this year, Shenzhou Lock Industry cooperated with the Criminal Security Brigade of Zhenhai Branch of Ningbo Public Security Bureau to “Safely Prevent the Community” and twice came to Huafeng Garden in Camel Street to replace the mechanical locks for residents in need. According to the relevant person in charge of the Criminal Investigation Brigade, the number of technical unlocking and theft cases in the community has dropped from 17 to 3 per month.

The 66-year-old Wu has passed the retirement age, but his research on locks has never stopped. In the interview, the reporter found that he has always been a "lock". "Serving ordinary people, so that thousands of households can use safe locks, is always my goal," he said.
