Abstract
Provided is an iron sofa frame structure provided with a base, two supporting plates oppositely disposed, configured to support a soft package and be connected with a sofa fabric and two driving link sets respectively configured to connect the two supporting plates to the base, wherein a front rod and a rear rod are correspondingly disposed at intervals between the two supporting plates, and several elastic bearing pieces for bearing the soft package are disposed between the front rod and the rear rod. The supporting assembly is directly combined to the iron sofa frame structure, so that a structure in which an additional seat-wrapped frame is introduced to support the soft package is rejected, an existing iron sofa frame structure and a production process of an iron sofa frame are simplified, the assembling and production efficiencies are increased, materials are saved, and the cost is reduced.
