Description

Section bar board connection structure and relevant furniture and fitment structure

Technical Field

The utility model relates to a section bar board technical field, in particular to section bar board connection structure and relevant furniture and fitment structure.

Background

The aluminum profile is an object with a certain geometric shape, which is made of aluminum materials and other metal materials with certain strength and toughness through processes of rolling, extruding, casting and the like. The material has certain appearance size, certain shape of cross section and certain mechanical and physical properties. The aluminum profile can be used independently and can be further processed into other manufactured products, and is commonly used for building structures and manufacturing and installation. The core plate unit after being generally subjected to plastic working (rolling, extrusion, drawing, forging, etc.) and mechanically cut is limited by the working space of the mechanical equipment itself, and the transverse width is not so long. When the aluminum profile with a large area is needed, a mode of splicing a plurality of inner core plate units is adopted. On the one hand, the surface of the aluminum profile with a large area can form splicing traces, and the problem of influencing the appearance still exists in a scene with a high requirement on the appearance degree. In addition, on the one hand, the aluminum alloy plate formed by splicing has the problem of insufficient mechanism strength due to the problem of splicing connection mode, and the firmness and stability of the aluminum alloy plate are influenced.

In addition, when the aluminum alloy section plates with the structure need to be assembled and spliced, if a welding mode is adopted, time and labor are wasted, the aluminum alloy section plates cannot be disassembled, and great trouble or incapability of carrying is brought to carrying; if adopt sticky mode, then connect insecure, have the potential safety hazard, also can't the later stage in addition dismantle.
