In addition, in order to reduce the storage space, the supporting legs of some chairs are designed to be foldable structures, but the existing foldable supporting legs have single structures and cannot be applied to tables or other equipment with larger weight.

Disclosure of Invention

The invention aims to provide a supporting foot structure which is simple in structure, can be stacked and can be automatically leveled so as to ensure that objects are horizontally placed and reduce the occupied space of storage.

The invention relates to a stackable automatic leveling supporting leg structure, which comprises a fixed seat fixedly arranged below an object, wherein a plurality of supporting legs are arranged on the outer wall of the fixed seat along the circumferential direction, the supporting legs are obliquely arranged, and the mounting heights of part of the supporting legs and the fixed seat are different; a cylindrical and rotatable torsion ring is arranged in the fixed seat, the rotation axis of the torsion ring is vertical, and torsion grooves are respectively arranged on the outer wall of the torsion ring and face the supporting legs; the connecting column is installed on the supporting legs, penetrates through the fixing seat and extends into the torque groove of the torque ring, the shifting teeth are arranged between the connecting column and the torque groove, and limiting structures for limiting rotation around a horizontal axis are respectively arranged between the connecting column and the shifting teeth and between the shifting teeth and the torque groove.

If the ground for placing the object is a horizontal plane, all the supporting legs are uniformly stressed, the torsion ring and all the supporting legs are in a balanced state due to interaction, and the object is horizontal; however, when the ground is uneven, if a place where one supporting leg is placed is convex, the supporting leg will rotate around the horizontal axis under the action of downward pressure, and the acting force generated by the rotation is transmitted to the rest supporting legs through the torsion ring and causes the rest supporting legs to rotate correspondingly until the reaction force between the supporting legs and the ground reaches a new balance state, the supporting legs will be static, and the object also reaches a required horizontal state. On the other hand, after the object is placed stably, the lower ends of the obliquely arranged supporting legs with lower height abut against the ground to serve as supporting points, and the higher ends of the obliquely arranged supporting legs with higher height are arranged on the fixed seat; meanwhile, the supporting legs with lower mounting heights can be inserted below the supporting legs with higher mounting heights to form overlapping in the height direction due to different high-end heights of the supporting legs, and a plurality of objects with the supporting leg structures are sequentially overlapped by the high-low supporting legs to finally form overlapping in the horizontal direction. Therefore, the object can be automatically leveled by using the stackable automatic leveling supporting leg structure, so that the placing stability of the object is ensured, and the difficulty of leveling the object is greatly reduced; meanwhile, the supporting leg structures can be transversely stacked, the stacking requirement is met, the occupied space is reduced, the stacking can be realized through transverse pushing during operation, the operation mode that the supporting leg structures are integrally lifted and then placed down like a traditional stacking chair is not needed, the operation convenience is greatly improved, and the supporting leg structures can be better suitable for objects with larger weight.
