Bed rail connecting assembly and bed rail

Abstract

The present disclosure provides a bed rail connecting assembly and a bed rail, which relates to the technical field of bed rails. The bed rail connecting assembly includes a first rail connecting piece, a second rail connecting piece and a locking assembly. When the locking assembly is at the locked position, the locking assembly is configured to limit the first rail connecting piece and the second rail connecting piece to hinder relative rotation between the first rail connecting piece and the second rail connecting piece. When the locking assembly moves to the released position under the action of an external force, the locking assembly releases the first rail connecting piece and the second rail connecting piece to allow the relative rotation between the first rail connecting piece and the second rail connecting piece.
