CENTERING STRUCTURE FOR AUTOMATIC CENTERING OF THE FLOATING JOINT.

Abstract

The invention proposes a centering structure for the automatic centering of a floating fixed base of a coupling, comprising a fixed base, a coupling, and a centering sliding assembly. The centering sliding assembly is movably received within the space of the fixed base and comprises a sliding body, a first elastic assembly, and a second elastic assembly. The first elastic assembly is used to provide the sliding body with the first elastic restoring force relative to the fixed base along the first direction. The second elastic assembly is used to provide the coupling with the second elastic restoring force relative to the sliding body along the second direction. Thus, after the coupling undergoes radial displacement due to forces during insertion and removal, the coupling automatically returns and maintains its center position through elastic restoring forces, solving the problem of misalignment.
