Spliced mechanical coded lock

Abstract

The invention discloses a spliced mechanical coded lock. The spliced mechanical coded lock comprises a lock body, a lock plate, a plurality of lock keys and a plurality of jigsaw keys, wherein the lock plate is inserted into the lock body, the lock plate is provided with a plurality of movable grooves, the plurality of lock keys are movably connected to the movable grooves in a penetrating mode, the lock keys are provided with clamping grooves, when all the clamping grooves are flush with the movable grooves, the lock plate can move in the lock body, and the jigsaw keys are detachably arrangedat the upper end and the lower end of the lock body and abut against the corresponding lock keys to move so as to switch the moving or locking state of the lock plate. According to the spliced mechanical coded lock, the jigsaw pieces are different in shape and have more than 70 shapes, due to the fact that the lengths of stand columns on the jigsaw pieces are different, the spliced pieces can bespliced to form more than millions of combination styles, millions of keys can be formed after the stand columns are combined, even if other people accidentally obtain the spliced pieces, correct graphs and correct stand column arrangement modes are difficult to splice, the combination transformability of the password sets is higher, and the safety degree is higher.

Description

technical field [0001] The invention relates to a mechanical lock, in particular to a spliced ​​mechanical combination lock. Background technique [0002] Mechanical lock is a kind of security facility, which is a device invented by human beings to protect their own property with a key. Mechanical locks are used to prevent items from being opened and removed. The lock is a fully mechanical combination lock with a large number of keys and high reliability without electronic devices. In this combination lock, multiple passwords can have multiple sets of passwords for the owner to change at will, and the confidentiality is extremely high. [0003] The existing application number is: 201820262814.6, a password storage box, which also uses the principle of puzzle pieces to unlock the lock, but the movement direction of the puzzle pieces is single, and the resulting code groups are less, which can be easily cracked by others, and the puzzle pieces are left on the lock directly , ...

Problems solved by technology

[0003] The existing application number is: 201820262814.6, a password storage box, which also uses the principle of puzzle pieces to unlock the lock, but the movement direction of the puzzle pieces is single, and the resulting code groups are less, which can be easily cracked by others, and the puzzle pieces are left on the lock directly , It can be tried many times by others when the owner is not at the scene, and it is more troublesome to open it. The shrapnel is used to open and lock. After a long time of use, the elasticity of the shrapnel will weaken, and it is more troublesome to open and close. , it is easy to cause incomplete reset due to the weakening of the elasticity, resulting in the situation that the lock cannot be closed
