The invention aims to provide a supporting leg structure which is simple in structure and capable of automatically leveling, so that an object can be horizontally placed, and the leveling adjustment difficulty is reduced.

The invention relates to an 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 side surface of the fixed seat along the horizontal circumferential direction; 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.

According to the automatic leveling supporting foot structure, the fixed seat is arranged below objects such as equipment and furniture and is pressed downwards by the gravity of the objects; the axis of the torsion ring in the fixing seat is vertical and can rotate around the axis, meanwhile, a torsion groove, a shifting tooth and a connecting column are arranged between the torsion ring and each supporting leg, so that the supporting legs can drive the torsion ring to rotate around the radial direction of the torsion ring, the torsion ring can rotate around two mutually vertical directions, and meanwhile, the torsion ring is mutually constrained with the fixing seat and the supporting legs and the shifting tooth on the two degrees of freedom, and acting force can be transmitted between the supporting legs through the torsion ring. 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. Therefore, the automatic leveling supporting leg structure can be used for automatically leveling objects, so that the placing stability of the objects is guaranteed, and the difficulty of leveling the objects is greatly reduced.

As shown in fig. 1-6, the fixing seat is installed under an object such as equipment, furniture, etc., and is pressed downwards by the gravity of the object; the axis of the torsion ring in the fixing seat is vertical and can rotate around the axis, meanwhile, a torsion groove, a shifting tooth and a connecting column are arranged between the torsion ring and each supporting leg, so that the supporting legs can drive the torsion ring to rotate around the radial direction of the torsion ring, the torsion ring can rotate around two mutually vertical directions, and meanwhile, the torsion ring is mutually constrained with the fixing seat and the supporting legs and the shifting tooth on the two degrees of freedom, and acting force can be transmitted between the supporting legs through the torsion ring. 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.

The supporting leg structure for automatic leveling, the limiting structure between the torque ring 3 and the shifting tooth 5, includes a limiting groove 32 extending from the torque groove 31 towards one side thereof, and a limiting tooth 51 extending from the shifting tooth towards the same direction; the limiting structure between the shifting teeth 5 and the connecting column 4 comprises a through hole 52 arranged on the shifting teeth, a limiting plane 53 is arranged on the side surface of the through hole, and a matched limiting surface 41 is arranged at the position, opposite to the limiting plane of the through hole, of the connecting column which penetrates through the through hole; when the supporting legs rotate due to the unevenness of the ground, the shifting teeth are driven to rotate by the limiting faces on the connecting columns, the shifting teeth drive the torsion ring to twist by the interaction of the limiting teeth on the shifting teeth and the limiting grooves, and finally the other supporting legs are driven by the torsion ring to realize automatic leveling. The structure of the limiting structure is very simple, but the operation is quick and stable, and the automatic leveling of the supporting legs can be effectively realized.
