Middle portions of the two C-shaped swinging rods are respectively connected to the sliding sleeves of the two support legs disposed along the front-to-rear direction through link rods.

Abstract: A device for connecting a cross member and a stand member of a bunk bed includes a support tube and a connecting tube. The end portion of the cross member is disposed with a connecting base that has a conical hole running vertically throughout. A shaft sleeve is disposed in the conical hole. The external surface of the shaft sleeve and the side surface of the conical hole form a pair of coupled slope surfaces. The end face of the connecting tube is disposed with a plurality of grooves, so the bottom end portion of the side wall of the connecting tube forms with a plurality of elastic clamping jaws. One end of the support tube is inserted to the connecting tube. The shaft sleeve is sleeved on the connecting tube, the connecting base squeezes the shaft sleeve to make the two slope surfaces, contact tightly.

Abstract: A structure for connecting a post and a beam of a bunk bed includes a support tube located above the beam. A connection tube is located below the beam. An end portion of the beam is provided with an insertion connection portion connecting the support tube and the connection tube. The insertion connection portion and the support tube have a pair of slanted surfaces disposed opposite to each other. When the support tube and the insertion connection portion are connected by insertion, the slanted surface of the insertion connection portion tightly fits the slanted surface of the support tube. The insertion connection portion and the connection tube have a pair of slanted surfaces disposed opposite to each other. When the connection tube and the insertion connection portion are connected by insertion, the slanted surface of the insertion connection portion tightly fits the slanted surface of the connection tube.

Abstract: The present disclosure discloses a folding hinge comprising an inner hinge piece and an outer hinge piece. Top edges of two side plates of the outer hinge piece are connected together by a connecting piece, and a slot is defined between the two side plates.
