Abstract:
A compact sofa iron frame structure, relating to the technical field of sofas. The compact sofa iron frame structure comprises a main frame (1) and a sliding frame (11), and an adjustment assembly (2) is provided on the main frame (1). The adjustment assembly (2) comprises: a driving rod (21) and a driven rod (22), the driving rod (21) and the driven rod (22) being both rotatably arranged on the main frame (1), and both having the other ends rotatably connected to a backrest; and a linkage rod (23), the linkage rod (23) being rotatably provided on the driving rod (21). A drive assembly (9) for driving a leg support (17) rotatably provided on the sliding frame (11) to rotate is provided on the main frame (1), and a fixing rod (19) for limiting the position of the leg support (17) is provided on the sliding frame (11). The drive assembly (9) is started to drive the leg support (17) to rotate to the outside of the sofa to support the legs; when the positions of a seat cushion and the backrest need to be adjusted, the drive assembly (9) is started again to drive the backrest and the driven rod (22) to rotate and move along with the seat cushion; thus, the back rubbing feeling caused by the backrest to the back is reduced, and even zero back rubbing feeling is achieved, thereby improving the comfort level of people when using the sofa.
