Male sleeve and female sleeve for bed frame

Abstract

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.

Description

technical field [0001] The invention belongs to the field of bed load-bearing row frames, and in particular relates to a fixed installation connection piece between rib bars and side frames of the row frame. Background technique [0002] The structure of the bed, after several centuries of development, has changed drastically until now, from the most primitive and simple straw bedding to the load-bearing of the bed board. Now that the technology is developed, it has also been tested by the market for a long time. The main part supports the mattress. Because of its reasonable structure and convenient installation, it has also become popular and has become the main load-bearing method adopted by various furniture factories at home and abroad, and the most direct way to protect mattresses. At present, the row frame generally adopts double row, three row, and reinforced type. The three row frames are designed to cater to consumers with different consumption levels. The frame o...

Problems solved by technology

Punching or drilling rectangular steel pipes or wooden squares will increase the cost of production equipment, processes and labor for manufacturers, as well as restrictions on the selection of rectangular steel pipes or wooden squares. Punching or drilling reduces the cost of rectangular steel pipes. Or the strength of the wooden square, it is easy to bend, crack, and break during the use of the finished product, which affects the service life of the row skeleton
