Marble anti-theft cipher lock and its key

Abstract

The marble anti-theft cipher lock includes case, lock master and lock bridge at the bulged site of the case ectotheca, and In the case there are 2 to 15lock masters with ring groove and semi-spoon delve at the bottom of the slot. The lock bridge marble is in the lock bridge marble finestra setup at the case and the corresponding lock bridge, and the bottom of slot semi-spoon delve anear the lock master combines as a spoon delve. There are two kinds of adapted keys, one is made up of the shank of the key and spoon body while the other is coded key including stationary shaft with conical key cobbra at one end, and key handle at the other end, and the stationary shaft is rung by the cipher cycle, washer and spring. The marble anti-theft cipher lock has double function of night lock and enciphered lock, the criminal must declassify the marble and search out of the corresponding place of each lock master at the same time. The effect of the anti-theft is good as the criminal can't unlock the lock without code when he gets the key as the dense key has cold ring.

Description

1. Technical field [0001] The invention relates to a tumbler cipher anti-theft lock, in particular to a tumbler cipher anti-theft lock with dual functions of a tumbler and a cipher and a matching key. 2. Background technology [0002] Existing locks can be roughly divided into combination locks and tumbler locks. Most of the combination locks are input passwords by buttons, character code runners and contacts. Therefore, the passwords are easily leaked during use. Because the unlocking passages such as keys and character code runners are all exposed, it is convenient for the thief to detect the password; secondly, the combination lock has too high requirements for the installation environment. Therefore, the applicability is far less than that of the tumbler lock; however, the tumbler lock has a relatively simple structure, but it is very easy to be opened violently or technically, the mutual opening rate is too high, and the anti-theft performance is poor. 3.
