180-degree overturning invisible sofa bunk bed

Abstract

The invention relates to the technical field of multi-functional sofas, and specifically relates to a 180-degree overturning invisible sofa bunk bed. The 180-degree overturning invisible sofa bunk bedcomprises an upper sofa seat and a lower sofa seat, wherein the lower sofa seat is internally provided with an installation frame; and a lower bed frame lifting connecting rod is arranged inside theinstallation frame. The 180-degree overturning invisible sofa bunk bed is characterized in that the installation frame is internally provided with an extension type lower bed frame; an overturning connecting rod is connected with the lower bed frame lifting connecting rod; the extension type lower bed frame comprises a lower bed frame and an extension bed frame; the extension bed frame is U-shaped; and two sides of the extension bed frame are slidably installed inside sliding grooves in the front and rear ends of the lower bed frame. The 180-degree overturning invisible sofa bunk bed has the advantages that the structure of a lower bunk is improved, an extension telescoping mechanism is added, the lying area of the lower bunk after unfolding is increased, and the sofa bunk bed is safer andgood in protection performance. The sofa bunk bed is light in weight, convenient for transportation, high in strength and long in service life. Through simple pull-up overturning operation, mutual conversion of a sofa and a bunk bed can be realized, the operation is simple and convenient, the space is saved, and the sofa bunk bed is applicable for houses with relatively small areas.

Description

technical field [0001] The invention relates to the technical field of multifunctional sofas, in particular to a 180-degree flip invisible sofa bunk bed. Background technique [0002] After the existing sofa bed is turned over, the lower bed is lifted and unfolded by the turning mechanism, but because the size of the lower bed is fixed, a large gap of 20-30 cm will be generated between the lower bed and the inner edge of the sofa after the lower bed is lifted. Moreover, the width of the lower bunk is relatively small, and the user easily falls into the gap when the lower bunk is turned over to lie on the side, and there is a certain safety hazard, especially when children are using it, they are more likely to fall and have accidents. When the parts are welded and connected, weld seams and burrs will appear at the welded joints. During use, it is easy to scratch bed sheets, quilts and other supplies. If the human body touches them, it may also cause the user's skin to be scra...
