Abstract
A lock structure at least includes a driving plank and a guidance mechanism. The guidance mechanism and the driving plank are mutually coupled at a same unlatch position via the guidance mechanism, or, the guidance mechanism and the driving plank are mutually coupled at a same lock position, which prevents the driving plank from wrong installation to avoid a destruction of the lock structure or reinstallation.
Claims11
A lock structure comprising:
- a driving plank rotatable between an unlatch position and a lock position;
- a guidance mechanism rotatable between the unlatch position and the lock position, wherein the guidance mechanism includes a leading barrel, an unlatch plate with a transmission hole, an opening disposed at the leading barrel and a guidance track which is a spiral track, wherein the leading barrel and the unlatch plate are synchronously rotatable, the leading barrel includes an alignment hole comprising a lateral surface, the guidance track is disposed at the lateral surface of the alignment hole, and the driving plank inserts into the leading barrel via the opening so as to rotate gradually via guidance of the guidance track and penetrates through the transmission hole;
- a control barrel wherein the unlatch plate is disposed within the control barrel;
- an elastic member disposed within the control barrel;
- and
- an actuation member configured to drive the driving plank to be rotatable between the unlatch position and the lock position.
