Kind Code:
A1
Abstract:
A folding lifting mechanism, comprising a lifting platform (1), and a first lifting column (2) and second lifting column (3) that are foldably assembled on the lifting platform (1) and that are adjustable in height. The end part of the first lifting column (2) is foldably assembled with a first supporting foot (4), and the end part of the second lifting column (3) is foldably assembled with a second supporting foot (5). The unfolded states between the supporting feet and the lifting columns and between the lifting columns and the lifting platform (1) are both fixed by means of quick locks (6). When unfolding, the lifting columns are perpendicular to the lifting platform (1), and the supporting feet are perpendicular to the lifting columns. When folding, the first supporting foot (4) is folded into the same long axis direction as the first lifting column (2), the second supporting foot (5) is folded into the same long axis direction as the second lifting column (3), the first supporting foot (4) is folded to one side of the center line of the long axis of the lifting platform (1) along with the first lifting column (2), and the second supporting foot (5) is folded to the other side of the center line of the long axis of the lifting platform (1) along with the second lifting column (3).
