The key comprises a key rod inserted and connected with the lock hole in a matched way, wherein rotating rings corresponding to the spring hole are sequentially sleeved in the axial direction of the key rod, and key grooves matched with different springs to be used are uniformly formed in the rotating rings. The coded lock provided by the invention has the advantages that one lock can have many codes, and the safety performance of the lock is improved. In addition, the key provided by the invention has the advantages that one key can unlock many locks, the keys of multiple locks are unified into one, the use is convenient, the cost is low, and the carrying is convenient.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a tumbler combination lock and a key. Background technique [0002] Locks have a long history. According to the definition of "Ci Hai", "a seal that can only be opened with a key is called a lock." In other words, if it can be opened without a key, it cannot be called a lock, at least not a real lock. Therefore, locks are mainly used for anti-theft and confidentiality. Since the invention of locks by humans, locks have played an irreplaceable role in people's lives. [0003] At present, most of the existing locks are ordinary pin locks with mechanical structure. The structure is simple. The principle is to use a plurality of cylindrical pins of different heights to lock the lock core. At the same height, the lock core can be rotated to drive the lock tongue to realize unlocking, but the structure of the key and the corresponding lock core structure of this kind of pin lock are fix...

Problems solved by technology

[0004] In order to solve the problem that the structures of locks and keys in the prior art and the corresponding lock cylinder structure are all fixed, and a key must be equipped with a lock, it is not only inconvenient to carry, but also easy to lose. Every time you open the door, you need to Try multiple times one by one whether the key is matched with the lock, the lock can only be unlocked after matching, the use is cumbersome, and the discrimination is poor. If the key is lost, the lock needs to be replaced in time to ensure safety. The purpose of the present invention is to provide a Pinball Combination Lock and Key
