Abstract:
A self-locking device with continuous locking positions includes a housing with an internal cavity, a wall of the cavity including a first frictional contact face and a fourth frictional contact face; a locking member with a second frictional contact face and a third frictional contact face, which is movable in the cavity, with the second and third frictional contact faces facing the first and fourth frictional contact faces, respectively; and a first lock block and a second lock block, with the first lock block being arranged between and contacting with the first and second frictional contact faces, and the second lock block being arranged between and contacting with the third and fourth frictional contact faces. The first and second lock blocks allow the locking member to be movable with respect to the housing in a first direction but locked in a second direction opposite to the first direction.
