General coded lock core

Abstract

A general coded lock core comprises a steel disc, a steel disc spindle, a sawtooth disc, a driving angle iron clamp and a stopping angle iron clamp. The lock core is equivalent to a lock cylinder of a key lock or a coded lock with a one-digit code, the lock core has no practical significance when being used separately, a practical coded lock with extremely high safety can be manufactured with multiple lock cores equipped with some auxiliary components, and the number of the lock cores is the digit of the coded lock. The lock core realizes setting, input, storage and decoding unlocking of the code in a pure mechanical manner. The coded lock manufactured with the lock cores is simple and convenient in code setting, quick and easy to unlock, stable in performance and purely digital, the safety performance of the coded lock is improved in a leap-type manner when being compared with that of various coded locks sold in the market at present, and the coded lock is applicable to various security doors, boxes and cabinets; the lock core can also be used for manufacturing a coded padlock, so that a user can get rid of the burden of keys and feel the convenience in life. Once the lock core is put into production, enormous economic and social benefit will be produced certainly.

Description

technical field [0001] The invention relates to a lock, in particular to a combination lock for installation and use on safety doors, boxes, cabinets and travel luggage. Background technique [0002] Locks are one of the most common property safety protection facilities in the world. With the improvement of people's living standards, property protection is becoming more and more important. In order to ensure property safety, the quality of various locks is getting higher and higher, but it is still not enough satisfy. For example, various combination locks for bags usually use number wheels to dial numbers and input codes. Although there are two types of number wheels that are vertical and parallel to the surface of the bags, no matter which one, there are only ten numbers from 0 to 9 on the number wheel. Set three, and the total number of passwords is one thousand. If someone wants to try the code to unlock, it will take a long time to find out the correct password, so its...

[0002] Locks are one of the most common property safety protection facilities in the world. With the improvement of people's living standards, property protection is becoming more and more important. In order to ensure property safety, the quality of various locks is getting higher and higher, but it is still not enough satisfy

For example, various combination locks for bags usually use number wheels to dial numbers and input codes. Although there are two types of number wheels that are vertical and parallel to the surface of the bags, no matter which one, there are only ten numbers from 0 to 9 on the number wheel. Set three, and the total number of passwords is one thousand. If someone wants to try the code to unlock, it will take a long time to find out the correct password, so its security performance is poor, and it is very laborious to dial the number wheel. Bring great inconvenience to the user; Another example is the combination padlock, which also has a similar situation; In the past, mechanical combination locks were easy, but because of the inability to jump to set the code, the length of the code for memorizing the code and inputting the code for unlocking made it difficult to remember the code and take a long time to enter the code, so it was not extended to general security doors. The amount of bit codes is very limited, and the total amount of passwords formed is not too much, giving people the feeling that the security is not enough

[0003] Can a kind of password lock be manufactured, it is easy for the owner to open it, but it is difficult for the thief to open it or even cannot open it at all in a short time? To make it easy for the owner to open it, it must be very easy to enter the password; to make it difficult for thieves to open it, the total amount of passwords must be greatly increased to prevent tentative or technical unlocking

However, the increase in the total number of passwords is closely related to the number of digits in the password and the number of digits on each bit, and is directly related to the difficulty of remembering the password and the length of unlocking time. How to solve the problem of increasing the total number of passwords without increasing the length of the password to facilitate memory , without increasing the code input time so that the lock can be unlocked quickly? After many tests, the only way to increase the total amount of passwords is to increase the number of digits of the password or the number of digits on each bit or both at the same time. The length of the lock will inevitably become longer, which brings difficulties to the memory, and the code input time will also be correspondingly longer, directly affecting the speed of unlocking and affecting the application prospects of the lock; if the number of bits on each bit is increased, although it will not increase The length of the password, but it brings difficulties to manufacture and also has a certain impact on the speed of code input
