The invention discloses a male sleeve and a female sleeve for a
bed frame. The female sleeve comprises a rectangular sleeve and two open hollow cylindrical concave buckles, wherein the two ends of the female sleeve are open, the two open hollow cylindrical concave buckles are arranged outside the rectangular sleeve, the inner
diameter of the opening of each concave buckle is smaller than the inner
diameter of the concave buckle, the openings of the concave buckles are connected with horn-shaped concave buckle leading-in protective wings, reinforcing ribs are arranged on the peripheries of the concave buckles, and a fixing hole is formed in the rectangular sleeve. The male sleeve comprises a
bed sleeve, horn-shaped positioning legs and cylindrical convex buckles, wherein the two horn-shaped positioning legs are arranged outside the
bed sleeve, the cylindrical convex buckles are arranged on the bottoms of the positioning legs, and the inner
diameter of each convex buckle is larger than that of the opening of each convex buckle and is smaller than that of each concave buckle. The rectangular sleeve is arranged in the bed frame in a sleeved mode, the convex buckles, at the two ends of a bed rib, of the male sleeve are inserted into the concave buckles of the female sleeve, and then the bed rib can be installed on and connected and fixed to borders of the bed frame. By the adoption of the male sleeve and the female sleeve for the bed frame, holes do not need to be punched or drilled in the boarders of the bed frame, production cost is reduced, productivity is increased, both disassembly and
assembly are convenient, and the bed frame is more durable. The male sleeve and the female sleeve for the bed frame are mainly applied to the field of supporting of berths, sofas, storage racks and the like.
