Title:
STACKABLE AUTOMATIC-LEVELING SUPPORTING LEG STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/138928
Kind Code:
A1
Abstract:
A stackable automatic-leveling supporting leg structure, comprising a fixed base (1) mounted below an object. A torsion ring (3) is provided in the fixed base; the connection columns (4) of supporting legs (2) penetrate through the fixed base and extend into the torsion grooves (31) of the torsion ring, and shifting gears (5) are provided between the connection columns and the torsion grooves; the supporting legs are obliquely arranged, and the mounting heights of some of the supporting legs and that of the fixed base are different, so that the stacking of the supporting legs in a horizontal direction can be formed; and when the ground is uneven, the supporting legs separately and adaptively rotate by means of the interaction of the torsion ring and the shifting gears, so as to achieve automatic leveling. The stackable automatic-leveling supporting leg structure can make an object achieve automatic leveling, and also can achieve stacking in the horizontal direction, reduces occupied space, is convenient to operate, and can be suitable for a heavy object.
