Description

Profile connecting piece and profile connecting structure Technical Field The present utility model relates to a section bar for manufacturing furniture, in particular to a connecting piece for connecting the section bar, and a connecting structure between the section bar and the connecting piece. Background The aluminum-profile furniture has the advantages of environmental protection, noise reduction, water resistance, fire resistance, durability and the like, so that the aluminum-profile furniture is more and more popular with users. The aluminum section furniture mainly adopts a strip-shaped aluminum section lap joint as a framework, and then panels made of different materials are arranged on the framework. Taking a door plate as an example, four long sections are connected into a rectangular frame, and then plates such as a wood plate, an aluminum plate and the like are arranged on the frame. The aluminum profiles are generally connected and fixed through mutual buckling or by adopting connecting pieces, and the connecting pieces are adopted to connect the profiles widely and commonly because the profiles which are mutually buckled are complex in structure, high in manufacturing cost and difficult to effectively ensure the connection strength, and the requirements on assembly and disassembly operations are high. The existing section bar connecting piece is L-shaped, two ends of the L-shaped connecting piece are inserted into the end parts of the section bar and are locked by screws, but other positioning or limiting structures are not arranged between the connecting piece and the section bar except the screws, so that the connecting strength is still limited, and the screws are easy to loosen. Disclosure of utility model The utility model aims to provide a profile connecting piece with high connecting strength and a profile connecting structure for connecting by using the profile connecting piece, so that the connecting strength between profiles is improved, and the stability and safety of the use of the profiles are improved.
