Abstract: A cushion and a nursing seat. The cushion comprises: a seat base (4031), and a through hole (4032) provided in a middle of the seat base (4031); a supporting structure (4033) disposed below the through hole (4032), and an accommodating space (4034) being formed between the supporting structure (4033) and the seat base (4031); and a collection box (8) detachably accommodated in the accommodating space (4034). The cushion is provided with the collection box (8) at the bottom, and may be used in the field of nursing. In addition, the collection box (8) and the cushion are detachably connected, thus facilitating handling and cleaning.

Abstract: A connecting structure and a seat. The connection structure comprises a mounting hole structure and a mounting structure correspondingly disposed on two main members to be connected; a step structure extends downwards and inwards on one side of the mounting hole structure, and two sides of the step structure are provided with limiting clamping points protruding in a direction parallel to an extending direction of the step structure; the mounting structure is configured to be a column structure, a bottom end of the column structure is provided with a shovel-shaped structure extending in one side of the column structure, and two sides of the shovel-shaped structure are provided with everted protrusions.

Abstract: The present invention relates to an assembly for an assembled container house system. The assembly includes: a first main wallboard, where the first main wallboard has a rectangular body; an upper right portion of the body of the first main wallboard protrudes rightwards to form a spherical protrusion, and a lower right portion extends rightwards to form an extension portion; an upper left portion of the body of the first main wallboard extends leftwards to form an extension portion, and a lower let portion protrudes leftwards to form a spherical protrusion; spherical recessed cavities are formed on front end surfaces of the two extension portions by means of being recessed backwards; the spherical protrusions match the spherical recessed cavities; and an axial direction of the spherical protrusion is perpendicular to an axial direction of the spherical recessed cavity.
