[0026] Embodiment 1

[0027] like Figure 1-Figure 4 As shown, a rotating sofa bed proposed by the utility model comprises a base 1, a folding assembly and an auxiliary support assembly. A pillar 2 is rotatably arranged on the base 1, a placement frame 3 with a U-shaped cross-section is arranged on the top of the pillar 2, and a folding assembly is arranged on the upper limit frame of the placement frame 3. The folding assembly has a sofa form and a bed form. When in the sofa form, it is in an L-shaped structure, and when in the bed form, the folding assembly is in a flat plate structure; an auxiliary support assembly is arranged at the bottom of the placement frame 3, which is used to auxiliary support the folding assembly arranged in the bed form.

[0028] like Figure 2 As shown, the folding assembly includes a horizontal plate 4 and a vertical plate 5 . The opposite ends of the horizontal plate 4 and the vertical plate 5 are rotatably connected via a rotating shaft, and a slot 6 is provided on the vertical plate 5 .

[0029] like Figure 4 As shown, a card plate 7 is provided at one end of the placement frame 3. When the folding assembly is in the bed form, the card plate 7 extends into the inner side of the card slot 6. When the folding assembly is in the sofa form, the inner side of the card plate 7 abuts against the vertical plate 5.

[0030] The vertical plate 5 is manually laid flat, and during the laying process, the card plate 7 is inserted into the card slot 6 .

[0031] Embodiment 2

[0032] like Figure 1-Figure 4 As shown, the utility model proposes a rotating sofa bed. On the basis of the above embodiment, this embodiment further discloses in detail the specific components of the auxiliary support assembly and the connection method between the auxiliary support assembly and the placement frame 3.

[0033] like Figure 2As shown, the auxiliary support assembly includes a fixed plate 8, a connecting plate 9, a telescopic fastener and a clamping column 11. The fixed plate 8 is provided with four groups, which are respectively arranged at the four corners of the bottom of the placement frame 3. The connecting plate 9 is rotatably arranged on the fixed plate 8. The bottom end of the connecting plate 9 is provided with a telescopic fastener, and the telescopic fastener is connected with a hook 10. The ends on both sides of the horizontal plate 4 and the vertical plate 5 are connected with the clamping column 11, and the clamping column 11 is engaged and connected with the corresponding hook 10.

[0034] like Figure 2 As shown, the telescopic fastener includes a rotating seat 12, a nut tube 13 and a screw 14. The rotating seat 12 is connected to the bottom end of the connecting plate 9, and its bottom is rotatably set on the nut tube 13 through a bearing. The screw 14 is connected to the inner thread of the nut tube 13, and one end of the screw 14 passes through the nut tube 13 and is connected to the hook 10.

[0035] Among them, the outer side of the nut tube 13 is provided with a shifting tooth, and by applying a rotational force to the shifting tooth, the nut tube 13 is conveniently driven to rotate.

[0036] like Figure 2 and Figure 3 As shown, both sides of the top of the placement frame 3 are provided with limiting slots 15, which cooperate with the clamping columns 11 to limit the horizontal board 4 in the sofa shape. When the folding assembly is folded into the sofa shape, the horizontal board 4 and the vertical board 5 are first lifted as a whole, and then moved laterally, so that the clamping columns 11 on the horizontal board 4 are correspondingly inserted into the limiting slots 15, thereby ensuring the limitation of the horizontal board 4.

[0037] In summary, when the utility model is in use, when it is necessary to set the folding component to the bed shape, first manually lift the vertical plate 5 and the horizontal plate 4 as a whole upward, so that the clamping column 11 is disengaged from the limiting slot 15, and then translate the whole body, so that the clamping column 11 on the horizontal plate 4 is disengaged from the placement area of ​​the placement frame 3, and then release the lifting force applied to the whole body, manually unfold the vertical plate 5, so that it is at the same horizontal position as the horizontal plate 4. During the unfolding process, the clamping plate 7 on the placement frame 3 extends into the inner side of the clamping slot 6; then manually rotate the auxiliary support component so that it points to the clamping column 11, and then fix the screw rod 14 with one hand and apply a force to the shifting tooth with the other hand to rotate the nut tube 13. During the rotation of the nut tube 13, since the screw rod 14 is threadedly matched with the screw rod 14, the screw rod 14 is screwed into the inside of the nut tube 13 until the hook 10 at the end of the screw rod 14 is clamped with the clamping column 11, thus completing the auxiliary support of the folding component in the bed shape. The overall operation is convenient, and the stability of the structure and the safety of use when the sofa is set to the bed shape are improved.

[0038] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
