As shown in fig. 1 to 4, the embodiment of the utility model discloses a household sofa which is convenient to disassemble, and comprises a sofa main body 1, a support rod 11, a cushion 2, a fixed component 4, a support spring 6, a limiting block 7, a limiting spring 71, a first sliding plate 8, a second sliding plate 81, a return spring 821 and a connecting cloth 83. The support rod 11 is a round rod-shaped structure, and the support rod 11 is arranged on the bottom surface of the sofa main body 1 and is used for supporting the sofa main body 1. The cushion 2 swing joint is on the inner wall of sofa main part 1 for improve staff's use experience.

The T-shaped groove 3 is formed in the inner bottom wall of the sofa main body 1, the L-shaped grooves 31 are formed in two opposite inner walls of the T-shaped groove 3, the fixing component 4 is arranged on the sofa main body 1 and used for fixing the cushion 2, and the fixing component 4 comprises a supporting rod 41, a first sliding rod 42, a second sliding rod 43 and a third sliding rod 44. The support bar 41 has a rectangular rod-like structure, and the support bar 41 is slidably disposed in the vertical portion of the T-shaped groove 3. The first slide bars 42 are of rectangular rod-shaped structures, the first slide bars 42 are provided with two first inclined surfaces 5 and are respectively arranged at two ends of the horizontal part of the T-shaped groove 3 in a sliding mode, and the edges, intersecting with the upper surfaces, of the side walls, close to each other, of the two first slide bars 42 are provided with the first inclined surfaces 5. The second sliding rod 43 is of a rectangular rod-shaped structure, the second sliding rod 43 is slidably arranged in the vertical part of the L-shaped groove 31, the side wall, close to the first sliding rod 42, of the second sliding rod 43 is provided with a placement groove 51, and the edge, intersecting with the side wall, close to the first sliding rod 42, of the second sliding rod 43, of the inner top wall of the placement groove 51 is provided with a second inclined surface 52. The third sliding rod 44 has a rectangular rod-shaped structure, the third sliding rod 44 is slidably disposed in the horizontal portion of the L-shaped groove 31, and a third inclined surface 53 is formed on an edge where the bottom surface of the third sliding rod 44 intersects with the side wall thereof, which is close to the seat cushion 2.

When the operator needs to install the cushion 2, the operator needs to make the surface of the cushion 2 and the surface of the connecting cloth 83 be connected to each other, and press the cushion 2 downwards, so that the supporting rod 41 can slide downwards under the action of the cushion 2, and the supporting rod 41 can simultaneously abut against the two first inclined surfaces 5, and then the two first sliding rods 42 slide in the directions away from each other, so that the two first sliding rods 42 sequentially abut against the adjacent second inclined surfaces 52, and then the two second sliding rods 43 slide upwards simultaneously. At this time, the two second slide bars 43 respectively abut against the adjacent third inclined surfaces 53, so that the two third slide bars 44 move in directions approaching each other and abut against the seat cushion 2, and the seat cushion 2 is kept stable under the action of the two third slide bars 44.

One end of the supporting spring 6 is fixed to the bottom surface of the second slide bar 43, and the other end of the supporting spring 6 is fixed to the inner bottom wall of the vertical portion of the L-shaped groove 31. Two limit grooves 61 are formed in the inner bottom wall of the horizontal part of the T-shaped groove 3, the limit block 7 is of a rectangular block structure, and the limit block 7 is arranged in the limit groove 61 in a sliding mode. One end of the limiting spring 71 is fixed on the side wall of the limiting block 7, the other end of the limiting spring 71 is fixed on the inner wall of the limiting groove 61, and the upper surface of the limiting block 7 and the adjacent first sliding rod 42 are mutually fixed.

When the worker applies a force to move the seat cushion 2 upward, the first slide bar 42 is returned by the stopper spring 71 and separated from the second slide bar 43, so that the second slide bar 43 moves downward by the support spring 6.

The first sliding plate 8 is of a rectangular plate-shaped structure, the first sliding plate 8 is fixed on the upper surface of the supporting rod 41, and the first sliding plate 8 is in sliding connection with the inner wall of the sofa main body 1. The surface area of the first slide plate 8 is much larger than the surface area of the support bar 41, so that the downward movement of the seat cushion 2 is improved, and the probability that the support bar 41 moves downward following the seat cushion 2 is improved, so that the stability of the device is improved.

The second sliding plate 81 is of a rectangular plate-shaped structure, the second sliding plate 81 is fixed on the side wall of the third sliding rod 44, which is close to the cushion 2, and a containing groove 82 matched with the second sliding plate 81 is formed on the inner wall of the sofa main body 1.
