Abstract

The invention discloses a multi-connecting rod angle adjustment sofa bed. The multi-connecting rod angle adjustment sofa bed comprises a backrest, a handrail, a base, a rear pedal plate, a front pedalplate and a steering moving part, connecting rods in the base are driven by pushing forward and pulling back an adjustment rod in the handrail, then the connecting rod slides in a connecting rod groove, the angle is changed through the linkage of the backrest, the front pedal plate and the rear pedal plate, the adjustment rod is located and locked at any angle through a locating part located in the handrail part, so that the sofa bed is located, and the sofa and the bed are moved and steered through universal wheels in the steering moving part. The multi-connecting rod angle adjustment sofa bed has the advantages that the inclination angle of the backrest and the pedal plates can be freely adjusted or simultaneously adjusted, meanwhile, the multi-connecting rod angle adjustment sofa bed has the advantage that the sofa and the bed can be freely moved and steered at a certain angle and the structure of the sofa is stable, reliable and compact, and the multi-connecting rod angle adjustment sofa bed has an extensive application value on the aspects of use and operation.
