Turntable coded lock capable of automatically clearing codes
The invention relates to a turntable coded lock capable of automatically clearing codes, which comprises a zero returning unit comprising a zero returning cam and a pawl, and the zero returning cam is arranged on a character wheel set; when the pawl is in contact with the zeroing part, the zeroing cam is locked; the matching part comprises a guide part arranged on the knob inner ring, and the spring bolt moves along the guide part and is matched with the locking groove and the unlocking groove, so that the character wheel unit has a locking state and an unlocking state; the spring bolt has a first stroke and a second stroke on the guide part; in the first stroke, the spring bolt is at least partially in contact with the inner surface of the guide part and moves along the inner surface; and after the character wheel set returns to zero, the spring bolt enters the second stroke, is located below the guide part and makes contact with the lower end face of the guide part. The password lock has the beneficial effects that the zeroing unit is arranged, and the guide part of a special structure is matched with the movable spring bolt, so that the password lock can be zeroed when being unlocked after being successfully unlocked, the possibility that a correct password is leaked is reduced, and the secrecy performance is higher.
本发明涉及一种能自动清码的转盘密码锁，包括回零单元，包括回零凸轮和棘爪，回零凸轮设置于字轮组上；棘爪和回零部位接触时，对回零凸轮进行锁定；配合部位包括设置在旋钮内圈上的的导向部，锁舌沿导向部移动并且与锁止槽和解锁槽配合，使字轮单元具有锁止状态和解锁状态；锁舌在导向部上具有第一行程和第二行程；在第一行程，锁舌至少部分与导向部的内表面接触，并且沿内表面移动；字轮组回零后，锁舌进入到第二行程，锁舌位于导向部的下方并且与导向部的下端面接触。本发明的有益效果在于：设置回零单元，通过特殊结构的导向部和活动锁舌配合，使密码锁在开锁成功后进行解锁时即可进行回零，减少正确密码被泄漏的可能，保密性能更强。
