Abstract
The invention relates to a two-pose locking mechanism which comprises a first link mechanism, a second link mechanism and an unlocking mechanism. The first link mechanism and the second link mechanism are connected. The unlocking mechanism is used for locking the first link mechanism and the second link mechanism. The two-pose locking mechanism has the self-locking function in two different poses and can be rapidly unlocked through a simple device and driven to be switched between the two different locking poses. When the two-pose locking mechanism is in the locking pose, external loading force or the loading moment is totally borne by rigidity of the mechanism, any driving force provided by a driving unit of an unlocking device is not needed, and therefore the requirement for the performance of the unlocking device by the locking mechanism is greatly lowered. The two-pose locking mechanism has the advantages of being ingenious in structure, reliable and practical.
