Bicycle stolen many times
　  Invented the lock yourself
Not long ago, Chen Lirong’s bicycle from the School of Manufacturing Science and Engineering of Sichuan University was once again “disappeared†on campus. Chen Lirong couldn’t bear to endure and decided to create a lock that could not be opened by car thieves. “The U-lock is too easy to open, and our classmates can open in 5 minutes, which is not safe at all.†Chen Lirong said that four of the previously lost bicycles were U-shaped locks.
When Chen Lirong told his friends Chen Ziqiang and Lei Jinyu, he got a positive response. "There may have been a bicycle loss experience, so it was a hit." The three of them set up a design team, ready to design a low cost, anti-theft High performance lock.
Chen Lirong's team first conducted an investigation in the market and found that although there are many types of locks, the anti-theft performance is not particularly good. So they decided to design a lock that would not leak the key parts of the lock cylinder.
After a period of experimentation, they conceived a key part of the lock cylinder and designed a sample that pulled the lock structure from the inside of the lock body and named it "J-lock".
Special locksmith test
Two improvements to complete the fourth generation of samples
After the “J-lock†is designed, it is necessary to practice the product performance. "We found the lock company from the Internet, informed the other party of our intentions, and then gave him the lock, asking them to try to open the J-lock sample." Chen Lirong introduced, when the J-lock was first handed to the locksmith, there was part People were still able to open, so they got some suggestions for improvement from the locksmith. After two improvements, the fourth generation J-lock sample was completed and renamed as “J-type double-row double-slot with closed door lock beadsâ€.
"In fact, like the ordinary lock structure, we just improved the design based on the traditional lock, changed the structure of the lock core and unlocked the lock hole. The lock hole was changed from the original U-shaped lock to the J-shaped Channel, the key is not zigzag, but J-shaped." Chen Lirong said that when unlocking, it also changed from the original insertion and unlocking to the key and then moved back and pulled back.
Chen Lirong also said: "Our lock, whether it is safety or cost-effective, is much better than the market." U-lock is easy to open because the key parts of the lock are exposed, and the characteristics of the J-lock Yes, there is no way to reach the key parts.
Integrated company released
There are already two products for sale on campus.
"I dare say that technology is unlocked, and we can't start with our locks." Chen Lirong said that because of the design of the isolation lock cylinder, special tools can not access the marbles, and it is even more impossible to violently unlock the locks. Broken. "Unless it is known that the J-lock internal lock core construction, it is difficult to open. And the J-lock is also smaller than the U-lock."
After the fourth generation J-lock, after repeated experiments, Chen Lirong's three-person design team decided to promote it to the market. “We first participated in the patent invention competition and obtained the national invention patent.†Chen Lirong said that in order to achieve market-oriented promotion and production, the team of three people began to raise venture capital and established research and development, production and sales. Ruiyi Technology Co., Ltd.
After the completion of the company, they first searched for J-type lock student agents in the campus of Sichuan University, and sold J-type locks in the form of other colleges and universities. "We have a total of 2 different price locks, 29 yuan and 39 yuan, respectively, and the price of other locks currently on the market is similar. Our 39 yuan J-lock can also resist hydraulic shear." Chen Lirong said, "The future, We want to develop into a well-known lock company that covers mechanical traffic locks and mechanical door locks. Locks are used to ensure the safety of citizens' lives and property."
