-
In the foregoing structures, seat body mounting racks 20 for mounting the first lower connectors 4a are fixedly fit on the seat body 2, and the first lower connectors 4a can be fixed by means of bolts or welding. Backrest mounting racks 30 for mounting the first lower connectors 4a are fixedly fit on the backrest 3, and the first lower connectors 4a can be fixed by means of bolts or welding. Armrest mounting racks 10 for mounting the first upper connectors 5a are fixedly fit on the armrests 1, and the first upper connectors 5a can be fixed by means of bolts or welding.
-
The first lower connectors 4a can be called lower connectors 4. The first upper connectors 5a can be called upper connectors 5. The connecting structures between the upper connectors 5 and the lower connectors 4 are as follows: during insertion, the upper connectors 5 are also snap-fit with the lower connectors 4 by means of buckle structures. Specifically, protrusions 6 are arranged on one of the upper connectors 5 and or the lower connectors 4, slots 7 are arranged on the other, and the protrusions 6 are snap-fit with the slots 7. In actual implementation, the protrusions 6 are fixedly fit with the upper connectors 5 and the slots 7 are arranged in the lower connectors 4. The locations of the protrusions 6 and the slots 7 can be swapped, i.e., the protrusions 6 are fixedly fit with the lower connectors 4, and the slots 7 are arranged in the upper connectors 5.
-
Further description of the foregoing connecting structures: the upper connectors 5 and the lower connectors 4 are all V-shaped structures with folded edges on both sides, the lower connectors 4 are slightly larger than the upper connectors 5, the upper connectors 5 are inserted onto the lower connectors 4, and during insertion fit, the lower connectors 4 are in interference fit with the upper connectors 5 through tapers generated by the V-shaped structures. Furthermore, alternatively, the upper connectors 5 and the lower connectors 4 can be designed as inverted-V- shaped structures and the upper connectors 5 can be designed as structures slightly larger than the lower connectors 4, and in this way, the upper connectors 5 can also be inserted onto the lower connectors 4 through the tapers in an interference fit manner.
-
In this embodiment, the sofa seat and the armrests 1 are mounted in an inserted manner, and the armrests 1 can be separately dismounted to facilitate storage and transportation. During mounting, the upper connectors 5 are aligned with and inserted into the lower connectors 4. The upper connectors 5 are in interference fit with the lower connectors 4 and the protrusions 6 will be automatically buckled with the slots 7 to prevent component loosening and disengagement during use of the sofa.
