Abstract

The utility model relates to the technical field of sofa frame structures, and discloses a push-pull sofa bottom frame convenient to transport, which comprises a bottom frame main body, an electric push rod and a sliding component, the bottom frame main body comprises two frames and two transverse frames which are arranged in a rectangular shape, and four corners of the bottom of the bottom frame main body are provided with supporting legs; a front frame and a rear frame are arranged at the two ends of the frame respectively, the height of the front frame is smaller than that of the rear frame, and a horizontally-arranged sliding rod is arranged between the front frame and the rear frame. The cylindrical sliding rod and the sliding block are combined, so that the requirement for long-term operation can be met, noise generated in the operation process is reduced, maintenance is easy, high abrasion resistance and corrosion resistance are achieved, dust is not prone to being accumulated, and the service life is long. Meanwhile, the structure is simple, the main body is of a split type frame structure, disassembly and assembly are convenient, and deformation and cost loss caused to the main body in the transportation process are reduced.
