Description

Iron art sofa bed

Technical Field

The invention relates to the technical field of clamp design, in particular to an iron sofa bed.

Background

The successive pretty of the small household furniture drives the brand new change of the furniture industry, and the small household furniture which is characterized by space saving, flexibility and convenience is favored. However, through detailed research and analysis on the use status of the small-sized furniture, the defects of the existing design result in the imbalance of the supply and demand of the small-sized furniture market, and the small-sized furniture which aims at modernization, humanization and intelligence is inevitably redesigned. Sofa beds are the most common of small-dwelling furniture, and are now the primary product in small-dwelling homes due to their functionality and utility. The sofa bed is also a sofa and can be used as furniture for bed use, and is more suitable for being used in places with limited space. In the prior art, a sofa bed generally needs to be manually lifted or put down as a sofa backrest to realize the function conversion between the sofa and the bed; or the sofa backrest is electrically controlled to be lifted or put down through the hinge and the pulley, so that the sofa backrest is inconvenient to use, the structure is not compact enough, and the sofa backrest is large in space and not suitable for being used in places with narrow space when being used as a sofa or a bed.

The chinese patent application with publication number CN204192095U provides a combined sofa bed, which comprises a fixed sofa bed and a movable sofa bed, wherein the movable sofa bed is fixed on a movable underframe, the movable underframe comprises a movable roller at the bottom, and the movable sofa bed comprises a lifting mechanism for driving a bed surface to lift; the movable sofa bed is positioned under the fixed sofa bed surface when in a contraction state, and the rear part of the underframe is provided with a driving motor which is matched with the rack at the bottom of the fixed sofa bed to drive the movable sofa bed to move out of the lower part of the fixed sofa bed surface to form an integral combined sofa bed. The whole switching process of the combined sofa bed is fully automatic when the combined sofa bed is driven by the oil cylinder, manual auxiliary switching is not needed, and the switching can be completed manually under the condition of power shortage, so that the combined sofa bed is complex in structure, large in occupied area and not easy to move although manpower can be saved.

Aiming at the defects of the common sofa bed, the iron art sofa bed is gradually raised, most of the iron art sofa beds in the current market are limited to the functions of the iron art sofa, and the existing pull-type iron art sofa bed realizes the dual-purpose functions of sofa and bed, but has relatively poor stability and durability; for iron art household products, the rust prevention treatment is very important, the drawing type iron art sofa bed is easy to rub and bump to drop paint in the drawing process, and the drawing type iron art sofa bed is easy to rust after the paint is dropped, so that the service life of the iron art household products is seriously shortened.
