Preferably, the method comprises the following steps: the connecting part is a screw. With the above structure, the handrail connecting part can be conveniently fixed on the handrail.

Preferably, the method comprises the following steps: and a chamfer is arranged at the notch position of the annular groove. By adopting the structure, the annular groove can be conveniently hung in the insertion groove.

Preferably, the method comprises the following steps: the upper end of the inserting groove is open, and the groove width at the open position is gradually reduced from top to bottom. By adopting the structure, the annular groove can be conveniently inserted into the inserting groove downwards.

Preferably, the method comprises the following steps: the notch is a U-shaped notch. By adopting the structure, the processing and the manufacturing are convenient, and the effective rotation of the control handle can be ensured.

The utility model also provides a sofa seat to the technical problem of the dismouting of being not convenient for of the handrail of solving traditional sofa seat, technical scheme is as follows:

a sofa seat comprises a seat body and an armrest which is detachably arranged on the seat body, and is characterized in that: still include above-mentioned joint subassembly, wherein connecting plate fixed mounting is on the lateral part of seat main part, handrail adapting unit's connecting portion fixed mounting is on the handrail.

By adopting the structure, when the armrest of the seat is installed, the operating handle is firstly rotated to enable the gap to be communicated with the insertion groove, then the annular groove is buckled on the side edge of the insertion groove from top to bottom, and after the annular groove at the lowest end completely enters the gap, the operating handle is rotated again to enable the gap to be closed, and then the installation of the armrest can be completed. The disassembly handrail can be reversely operated according to the process, so that the operation is very convenient, and the time and the labor are saved.

Compared with the prior art, the beneficial effects of the utility model are that:

adopt the utility model provides a joint subassembly and sofa seat convenient to installation has realized the bare-handed dismouting of no instrument, and the operation is convenient, labour saving and time saving, and assembly back compact structure, good reliability, joint strength is high.

Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1 and 3, a sofa seat mainly comprises a seat body 4 and armrests 5, wherein the armrests 5 are detachably mounted on the side portion of the seat body 4 through a clamping assembly, the clamping assembly is composed of a connecting plate 1, a control handle 2 and an armrest connecting part 3, the connecting plate 1 is fixedly mounted on the side wall of the seat body 4, and the armrest connecting part 3 is fixedly mounted on the inner side wall of the armrest 5.

As shown in fig. 2, the upper end of the connecting plate 1 is provided with an insertion groove 1a formed by extending along the vertical direction, the upper end of the insertion groove 1a is open, the groove width of the open position is gradually reduced from top to bottom, and the bottom end of the insertion groove 1a is provided with a rotating groove 1 b.

The operating handle 2 is in a plate-shaped structure, a supporting platform 2b which is in rotating fit with the rotating groove 1b is arranged on the side wall of the upper end of the operating handle, a notch 2a is arranged at the position corresponding to the supporting platform 2b, the notch 2a is in a U shape, and the notch 2a can be closed or communicated with the inserting groove 1a by rotating the operating handle 2.
