Assembly Structure Of Sofa Base

Abstract

An assembly structure of a sofa base, being related to a technical field of sofas, includes a mounting frame, a backrest, and an assembly mechanism. The backrest is disposed on an upper surface of the mounting frame. The assembly mechanism includes supporting legs, supporting plates, and connecting blocks The supporting legs are fixedly connected to a side surface of the mounting frame through bolts, the supporting plates are welded to an inner side of the mounting frame, the connecting blocks are clamped at one end of the mounting frame, and the connecting blocks are fixedly connected to the backrest. The mounting frame is fixedly connected to the supporting legs through a welding mode to form a whole. Meanwhile, the supporting plates are clamped in an interior of the mounting frame, so that the supporting plates are in close contact with a connecting rod.
