Bicycles are stolen and determined to develop locks

In the winter of 1990, Liu Baosheng bought a bicycle for a month's salary, and Liu Baosheng happily rode his car to work. It was not good for a long time. One day, Liu Baosheng found out that the lock used to lock the car was thrown off the thief and thrown on the ground. The bicycle disappeared. Then, Liu Baosheng’s bicycles were also stolen. In just half a year, three bicycles were stolen from home. Moreover, the neighbors’ cars are often lost, and some people’s home doors are smashed.

In the early years, Liu Baosheng, an old man who specialized in the factory, has always been a technical expert in the factory. Liu Baosheng thought about the old man, why not make a solid lock on his own, so the thief would not be so easy to get it.

Liu Baosheng finally grasped the basic structure of the lock by disassembling more than 60 locks. At that time, he was still at work, studying locks can only use spare time, after half a year of painstaking research, Liu Baosheng's first lock came out. Although it seems that the technology, technology and style of the first lock are not very mature. However, it really inspired Liu Baosheng's enthusiasm for researching locks. Since then, Liu Baosheng has been constantly innovating and transforming locks, which has been done for more than 20 years.

I don’t touch the lock for two days.

At the beginning, Liu Baosheng's tools for making locks were all patchwork. The production of locks was also a spare time, just a hobby. In 1993, Liu Baosheng was retired at home, and the time for studying locks gradually increased. As the research progressed, he found that his “addiction” was also growing. According to Liu Baosheng, a large part of the design and manufacture of these locks was completed at one or two in the morning. Sometimes, when I was asleep, I suddenly got an idea, and I immediately got up and put these ideas into action.

Each of these locks developed by Liu Baosheng was tested several hundred times in person to ensure quality. Liu Laoxiao said, "The locks you can't do can't be used to prevent thieves. You can't open them yourself!" So, these locks made by Liu Baosheng for the elderly ensure that the user can open in about 40 seconds. In Liu Baosheng's view, the sound of "squeaking" that opens and closes the lock is the most beautiful music. Now if you don't touch your lock for two days, don't draw drawings and pick up the scorpion, Liu Baosheng can't eat and can't sleep.

More than 20 years of research results

Up to now, Liu Baosheng has developed 36 types of locks, including 29 electric vehicles, 29 motorcycle locks, 2 safe locks, 2 steering wheel locks, 2 door locks and 1 bicycle lock. Of these locks, eight have won national patents. Moreover, the locks invented by Liu Baosheng were selected in the book "China Contemporary Technology Innovation Expo" in 1999, and three manufacturers have purchased invention patents for the elderly.

These locks undoubtedly condense the efforts of Liu Lao. One of the safe locks took nearly five years for the elderly, and it was made after hundreds of experiments. Referring to the quality of the locks, the old man said with pride: "Since the children used the locks I made, I never lost the car."

Recently, the two steering wheel locks newly invented by Liu Baosheng were completed. The difference between the two steering wheel locks and the other locks is that the cars can only go straight after the two locks are locked. Moreover, these two locks can temporarily act as a safety hammer in an emergency, and open the glass to escape.

After more than 20 years of research, in addition to the emergence of so many new locks, the elderly have also gained a healthy body, the joy of life and the constant transcendence of self. Whenever a new lock is developed, Liu Baosheng always thinks about whether he can make some more innovations and then improve the security level. Now, the old man intends to go to the relevant departments in Beijing to identify the security level of these locks, and also to find companies or individuals with economic strength and interest in locks to cooperate or transfer technology, so that more ordinary people can use them with confidence. Safe locks.
