[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 This embodiment provides a sofa armrest flipping and moving structure, including two first connectors 1, two second connectors 2, and a connecting rod 3. The first end of the first connector 2 is used to connect to the sofa armrest 4, the second end of the first connector 2 is rotatably connected to the first end of the second connector 2, the second end of the second connector 2 is used to rotatably connect to the sofa seat frame 5, and the two ends of the connecting rod 3 are respectively connected to the two second connectors 2.

[0030] In actual use, the first connector 1 and the second connector 2, and the second connector 2 and the sofa frame 5 are connected by a shaft-hole fit to achieve a rotating connection, such as screws or pins and holes fit together for installation.

[0031] In the embodiment, the first connecting member 1 and the sofa armrest 4 are connected by screws, facilitating the disassembly of the first connecting member 1 and the sofa armrest 4. In order to improve the assembly aesthetics and flatness, a tapered hole can be provided on the first connecting member 1, so that the screw cap part can be located in the tapered hole. Of course, the first connecting member 1 and the sofa armrest 4 can also be connected by pins or rivets or mortise and tenon structure.

[0032] In the embodiment, referring to Figures 1 to 4 , the first connecting member 1 has a bending part near the side close to the second connecting member 2, and the first end of the second connecting member 2 and the bending part of the first connecting member 1 are rotationally connected.

[0033] In the embodiment, referring to Figures 1 to 4 、 Figure 6 , the first connecting member 1 has a limiting socket 11, and when the sofa armrest 4 is in a vertical state, the limiting socket 11 is just clamped on the sofa seat frame 5, which can improve the firmness of the sofa armrest 4 in the vertical state.

[0034] In the embodiment, referring to Figures 1 to 4 , the second connecting member 2 is provided with a first bending part and a second bending part, the first bending part is rotationally connected with the first connecting member 1, and the second bending part is rotationally connected with the sofa seat frame 5, further improving the smoothness of the rotation of the first connecting member 1 and the second connecting member 2.

[0035] Further, referring to Figures 1 to 4 , the first bending part and the second bending part are parallel to each other, the corner formed after the first bending part is bent is away from the first connecting member 1, and the corner formed after the second bending part is bent is close to the first connecting member 1, so that a gap is left between the rotation connection position of the first connecting member 1 and the second connecting member 2 and the sofa seat frame 5, further improving the smoothness of the rotation of the first connecting member 1 and the second connecting member 2.

[0036] Referring to Figures 1 to 9The sofa further includes a sofa armrest 4, a sofa seat frame 5, a cushion 6, and a backrest 7. One of the sofa armrests 4 is connected to the sofa seat frame 5 by the sofa armrest flip-over moving structure, and the other sofa armrest 4 is connected to the cushion 6 or the backrest 7. The cushion 6 is slidably installed above the sofa seat frame 5, and the backrest 7 is arranged on the cushion 6. When the sofa seat frame 5 is pulled to move outward by a distance in the direction of the sofa armrest flip-over moving structure, the sofa armrest 4 is flipped over downward to horizontally place part of the sofa armrest 4 above the sofa seat frame 5. The part of the sofa armrest 4 outside the sofa seat frame 5 is lifted and pushed to move horizontally inward, so that the sofa armrest 4 is completely placed above the sofa seat frame 5 to form a bed shape. When the sofa armrest 4 is pulled to move horizontally outward and flipped over upward, the sofa armrest 4 is repositioned on the side of the sofa seat frame 5. The sofa seat frame 5 is pushed to move inward until the sofa armrest 4 abuts against the cushion 6 and the backrest 7 to form a sofa shape.

[0037] In the sofa shape, the backrest and the cushion horizontally block the sofa armrest, and the limiting socket of the first connecting piece is clamped on the sofa seat frame to produce a longitudinal blocking effect, so that the sofa armrest is not easy to fall over. The width of the sofa armrest 4 is less than the total width of the cushion 6 and the backrest 7, and the outward moving distance of the sofa seat frame 5 is less than or equal to the height of the sofa armrest 4, so that the sofa seat frame 5 supports the bottom of the sofa armrest 4 on both sides to ensure stability. When the sofa armrest 4 is folded from a vertical state to a horizontal state, the rotation angle of the first connecting piece 1 is 90°. During the process of flipping over the sofa armrest 4 downward, the angle of the second connecting piece 2 changes from 0° to 45°. After part of the sofa armrest 4 is placed above the sofa seat frame 5, the angle of the second connecting piece 2 changes from 45° to 0°. During the process of lifting the sofa armrest 4 and pushing the sofa armrest 4 to be completely placed above the sofa seat frame 5, the rotation angle of the second connecting piece 2 changes from 0° to 180°.

[0038] In this embodiment, referring to Figure 6 and Figure 7 , the sofa seat frame 5 has a storage cavity inside for placing articles, and the sofa seat frame 5 is provided with support legs at the bottom, which facilitates users to place articles in the storage cavity and has a certain storage function.

[0039] In this embodiment, the bottom of the cushion 6 is hiddenly provided with a folding support leg. When the sofa seat frame 5 is pulled to move outward, the folding support leg is unfolded to be supported on the ground, thereby improving the stability of the use of the cushion. The folding support leg is a prior structure, and the support leg can be folded by 90 degrees. In order to improve the installation flatness, a groove for storing the folding support leg can also be arranged on the cushion.

[0040] In the embodiment, the top of the sofa seat frame 5 is provided with a sliding rail, the both ends of the sliding rail are provided with a baffle, the bottom of the cushion 6 is provided with a sliding block, the sliding block is matched and installed on the sliding rail, and the sofa seat frame is convenient to pull out. Of course, in order to realize the sliding connection between the sofa seat frame 5 and the cushion 6, a sliding groove can also be arranged at the top of the sofa seat frame, and a roller is arranged at the bottom of the cushion, and the roller linearly slides in the sliding groove.

[0041] The above embodiment is a description of the utility model, not a limitation of the utility model, and any simple transformation of the utility model belongs to the protection scope of the utility model.
