Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a semi-split sofa structure. Background Art

[0002] At present, there are two main connection methods for assembling and connecting the sofa armrest and the seat frame on the market: one is an integrated structure, specifically, the front end plate and the rear end plate of the seat frame both protrude to the left and right sides, and some reinforcing connecting plates are added between the protruding portion on the left side of the front end plate of the seat frame and the protruding portion on the left side of the rear end plate of the seat frame to form the left armrest; similarly, some reinforcing connecting plates are added between the protruding portion on the right side of the front end plate of the seat frame and the protruding portion on the right side of the rear end plate of the seat frame to form the right armrest. The advantage of the one-piece structure is that the seat frame and the armrest share the front end plate and the rear end plate as their own end plates, and the connection between the seat frame and the armrest is relatively firm; the disadvantage is that the armrest needs to be made at the same time when the seat frame is made, and the production process is relatively complicated; the other is a split structure, that is, the armrest and the seat frame are completely independent of each other, and there are no common parts between the two. The two can be produced separately, but are later assembled and connected by bolts or screws. The advantage of the split structure is that the structure is simple and easy to produce and process. The disadvantage is that since there are no common parts between the armrest and the seat frame, the overall stability of the armrest and the seat frame after being connected is not strong, especially at the connection position between the two, the firmness is insufficient.

[0003] Based on the above, it can be known that existing sofas usually cannot take into account both stability and processing convenience; and in order to solve this technical problem, a semi-split sofa was authorized and disclosed on July 15, 2022, and its authorization announcement number is CN216961969U. The utility model includes a seat frame and an armrest arranged on the outside of the seat frame. The front end of the armrest is fastened to the front end of the seat frame by a fastener, and the rear end of the armrest and the rear end of the seat frame share a rear end plate. The front end of the armrest is connected to the front end of the seat frame by fastener bolts to meet the requirements of convenient processing of the front end of the armrest. The rear end of the armrest and the rear end of the seat frame adopt a common rear end plate to strengthen the stability of the connection between the armrest and the seat frame.

[0004] However, the prior art still has certain defects in using fasteners to connect the front end of the armrest and the front end of the seat frame: during installation, the fasteners need to be fixed between the front end of the armrest and the front end of the seat frame by bolts, which has a complex structure, is inconvenient to install, and has low installation efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a semi-split sofa structure.
