No battery, circuit, full mechanical control, password length up to 40 digits. This is the "mechanical CNC lock" invented by Mr. Quan of Shunde Dalian. This lock was awarded the "utility model patent certificate" issued by the State Intellectual Property Office on March 8, 2001. Yesterday (March 27), Mr. Quan told reporters: "With a mechanical CNC lock, you can go out without a key, even if you have a power outage, you can use it as usual."
Key password is compatible
Yesterday, Mr. Quan showed his reporter the mechanical CNC lock model. The reporter found that the lock was equipped with a ring 0~9 number button and button between the rotating handle and the keyhole. Mr. Quan just pressed a few numbers, then turned the knob clockwise and the door lock opened. "I used to decorate. At that time, I had to go through a few decoration points in one day. Keeping the keys for the customers became a headache for me. I often confused them. I wanted to design a password lock without a key. I don't have to bring so many keys," said Mr. Quan.
Then, Mr. Quan unscrewed the small screw on the edge of the door, took out the device of the ring-shaped digital button, and set the password with a thin rod on the wheel behind the device. Mr. Quan said: "Although the password setting method is very simple, each number can be selected 4 times from 0 to 9. The entire password can be up to 40 characters. It is believed that this number of passwords is difficult to crack."
"Now the password lock I designed is completely mechanical CNC, no battery or plug-in power supply. And the lock can be opened with the key and password. If you have the key, you can use the key, forget to bring the key, you can still open the door with the password. There is also a simple device, you can choose to cancel the password and the key compatibility. So there is no password, only the key can not enter the door. That is to say, the thief steals the key, if you do not know the password, you can not enter the house." Mr. Quan said.
Continue to improve and hope to start production
It is reported that Mr. Quan began to study and design the lock in 1995 and obtained the national patent in 2001. Since then, he has not stopped improving the aesthetics and performance of the lock.
"I am making a new template, plus a small device that eliminates key and password compatibility, and an alarm that continuously enters the password 4 times in error. In addition, add the luminous powder to the number on the button to let the person return home at night. I can clearly enter the password." Mr. Quan said, "I hope this patent can be contacted by the manufacturer as soon as possible. Because the lock is easy to use, the cost is only 10% of the electronic password lock on the market. I am also developing the motorcycle at the same time. The mechanical CNC lock on the car, if developed, is believed to cause headaches for those motorcycle thieves."
