Note: If the user forgets the password, the user can only choose a few possible passwords to try to open. If he still can't open it, he can only enter from the window and open the door indoors. Manufacturers can't help. If the key is lost, you can ask a professional to open it.
The inventor intends to cooperate with a professional factory to produce (the other party is responsible for production, I am responsible for sales), or other means of cooperation or patent transfer.

New anti-theft door mechanical code lock patent search cooperation
At present, the password locks installed on the security door have two types of electronic type password locks (including fingerprint locks, push-button locks, mobile phone electronic locks, etc.) and mechanical password locks. Among them, the electronic type code lock needs to be replaced in time or charged in time. In addition, its electronic components are easily aging and damaged, and more importantly, the price is too expensive, generally requiring several thousand dollars. Therefore, the promotion of electronic code locks is difficult, and the market share is small.
There are two main types of mechanical type code locks: push-button mechanical code locks and dial-type mechanical code locks. These two types of password locks are not scientifically designed, and there are problems such as too little password capacity, difficulty in changing passwords, and poor security. Therefore, its promotion is also very difficult.
The "rotary mechanical code lock" that was recently invented by Zeng Yifeng's senior engineer was very scientific and beautiful in appearance (the picture is a lock panel). The function is unique, and has the following characteristics:
1, the password capacity is particularly large, each lock is designed with 10 password wheels, the same lock has a choice of several billions of passwords, so if you do not know the lock password and want to open, the difficulty is conceivable know.
2, the password is easy to remember, the user's special day can be selected as the password, such as the child's birth time: 08:00 on August 08, 2012, that is, the user can set the password to 2012080806, which is more than the password insurance of the bank card.
3, the password is easy to change, the user can change the password of the lock at any time as needed. You only need a needle-nosed pliers to change your password, you don't need to open the lock box. When you suggest to change your password, tell the rest of the family, everyone to remember, and at the same time the password is stored in the mobile phone memo.
4. There is no collision sound inside the lock when each code wheel is rotated. Therefore, it is impossible to perform technical unlocking by tools such as a stethoscope.
5, lock the door and open the door is simple to operate, blind people can also operate.
6. The lock is also equipped with a common marble lock cylinder, so it is actually a combination of two locks. Users can choose different locking methods according to the needs of different time: only use the password lock to lock the door or only use the marble lock to lock the door, or use two locking doors at the same time, which can further improve the insurance factor.
7. The lock is designed with two inner and outer handles. When the outer handle is locked on the combination lock, it will not damage the internal parts, no matter how much it is rotated. It is also impossible to open the lock if the outer handle is cut.
8. The indoor person can unlock the door simply by turning the inner handle. After the indoor person locks the door, it can allow the outdoor person to unlock with a password (such as waiting for the family to return from the opened door), or control the outdoor person to open the door to ensure safe sleep.
9, the lock system is easy to make, assembly and installation is not difficult.
