Embodiment Construction

[0016] by figure 1 , figure 2 It can be seen that this embodiment has four code discs 101, four rotating shafts 102, four rotating shaft springs 1023, four lock plates 605, lock plate springs 606, code adjustment plate 500, lock plate 604, lock plate spring 607, and shaft 102 The lock plate 605 is driven to move by rotating the cam 1022 to block or release the lock plate 604. The movement of the lock plate 604 can realize unlocking or locking; the rotating shaft 102 is installed on the code adjusting board 500, and the connecting rod 502 is installed on the code adjusting board 500. The connecting rod 502 is connected to the encoding screw 501 in the panel 200. When the encoding screw 501 is turned, the encoding board 500 and the four rotating shafts 102 can be moved back and forth as a whole, so that the four rotating shafts 102 are separated or connected to the four code discs. 101; In the state where the cipher disc 101 is separated from the rotating shaft 102, rotate the c...

Abstract

The invention discloses a mechanical coded lock which comprises a password disc (101), and further comprises a panel (200), a rotating shaft (102), a lock sheet (605) and a code modulating plate (500), wherein by rotating the rotating shaft (102) and a cam (1022), the lock sheet (605) is driven to move to lock or release the a locking plate (604), and with the moving of the locking plate (604), locking or unlocking can be achieved; the rotating shaft (102) is arranged on the code modulating plate (500); by moving the code modulating plate (500), the rotating shaft (102) is released from or connected to the password disc (101); and the password disc (101) is rotated to modulate the code under the state that the password disc (101) is released from the rotating shaft (102). The coded lock disclosed by the invention is high in technical unlocking performance, compact in structure and reliable in performance, and is specifically applicable to the emergency unlocking of a fingerprint lock.

Description

Technical field [0001] The invention relates to a lock core, especially a mechanical code lock. Background technique [0002] A code lock is a type of lock, which uses a series of numbers or symbols to open. The code of the combination lock is usually just a permutation rather than a real combination. Some code locks only use a turntable to rotate several discs or cams in the lock; some code locks rotate a set of dial wheels engraved with numbers to directly drive the mechanism inside the lock. [0003] For example, multi-dial code locks, which are common in bicycle locks with low security settings, use multiple dials. There is a recess in the middle of each circle. There are several protruding teeth on a shaft in the center of the lock to hold the dial ring. When the dial ring is turned to the correct combination, the lock can be opened. This kind of lock is the easiest to open. Many of these locks can be opened without knowing the password. Unless its internal components ...
