[0017] The following will be further described in detail with the specific embodiments of the utility model. It should be understood that the description of the embodiments of the utility model herein is not used to limit the protection scope of the utility model.

[0018] As Figures 1 to 4 ​​​As shown, it is the structure schematic drawing of the sofa with turnover structure provided by the utility model. The sofa with turnover structure comprises a base support 10, two handrail supports 20 fixedly connected to both sides of the base support 10, a backrest assembly 30 rotatably connected to the base support 10, and two limiting devices 40 arranged on the handrail supports 20 respectively. The sofa with turnover structure further comprises other functional modules such as assembly components and the like, which should be the technology known to the person skilled in the art and will not be described in detail here.

[0019] The base support 10 is the base of the sofa, and the base support 10 is used for supporting the user. The base support 10 is a prior art and will not be described here.

[0020] The handrail supports 20 are fixedly arranged on both sides of the base support 10 to ensure the stability of the handrail supports 20 on the base support 10. The base support 10 and the handrail supports 20 are integrally formed. The handrail supports 20 are a prior art and will not be described here.

[0021] The backrest assembly 30 comprises a backrest support 31, at least two limiting holes 32 arranged on both ends of the backrest support 31 respectively, and at least one rotating connecting piece 33 connected between the backrest support 31 and the base support 10.

[0022] The backrest support 31, the base support 10, and the handrail supports 20 can be provided with decorative surfaces (not shown in the figure). The decorative surfaces can be any one of sponge pads, cloth, and rattan strips to improve the aesthetic appearance of the backrest support 31, the base support 10, and the handrail supports 20. The fixing structure between the decorative surfaces and the backrest support 31, the base support 10, and the handrail supports 20 is a prior art and will not be described here.

[0023] The limiting holes 32 are used for cooperating with the limiting devices 40, so the limiting holes 32 will be described in detail in combination with the limiting devices 40 and will not be described here.

[0024] The rotating connecting piece 33 is arranged between the backrest support 31 and the base support 10 to realize the rotational adjustment of the backrest support 31 on the base support 10. The rotating connecting piece 33 is a prior art, and the rotating connecting piece 33 is any one of a hinge and a connecting pin. In the embodiment, the rotating connecting piece 33 is a hinge.

[0025] Each of the limiting devices 40 comprises a limiting socket 41 arranged on the armrest support 20, a plug rod 42 slidingly arranged in the limiting socket 41, and a positioning pin 43 fixedly connected to the armrest support 20.

[0026] The limiting socket 41 is fixedly connected to the armrest support 20, and the fixed connection structure between the limiting socket 41 and the armrest support 20 is a prior art which will not be described here.

[0027] The plug rod 42 has an "L" shaped outer contour, i.e. a bending section is arranged on the plug rod 42, so as to facilitate the user to drive the plug rod 42 to slide on the limiting socket 41. The plug rod 42 is arranged in the limiting socket 41 and can slide on the limiting socket 41 to limit the position of the backrest assembly 30. The sliding connection structure between the limiting socket 41 and the plug rod 42 is a prior art which will not be described here.

[0028] The positioning pin 43 is fixedly connected to the armrest support 20, and the positioning pin 43 is used to limit the position of the backrest assembly 30 arranged on the base support 10 when the backrest assembly 30 is unfolded. The positioning pin 43 is a prior art.

[0029] When the backrest assembly 30 is unfolded and arranged on the base support 10, the side of the backrest assembly 30 away from the base support 10 abuts against the positioning pin 43 to limit the rotating position of the backrest assembly 30, and the limiting hole 32 corresponds to the limiting device, the plug rod 42 is arranged in the limiting hole 32, thereby limiting the position of the backrest assembly 30 on the base support 10. When the backrest assembly 30 is unfolded and arranged on the base support 10, the included angle between the backrest assembly 30 and the base support 10 is 120 degrees, so as to improve the comfort of the user during use.

[0030] When the backrest assembly 30 is folded, the plug rod 42 is separated from the limiting hole 32, and the backrest support 30 is parallel to the base support 10, so as to reduce the space between the backrest support 30 and the base support 10, thereby facilitating the transportation of the sofa.

[0031] Compared with the prior art, the sofa with the turnover structure is connected to the base support 10 through the backrest assembly 30, and the position of the backrest assembly 30 is limited through the limiting device 40. The backrest assembly 30 comprises a backrest support 31, at least two limiting holes 32 arranged at the two ends of the backrest support 31 respectively, and at least one rotating connecting piece 33 connected between the backrest support 31 and the base support 10. The backrest assembly 30 is connected to the base support 10 through the rotating connecting piece 33, so that the position of the backrest assembly 30 on the base support 10 is adjusted. In addition, the limiting device 40 is arranged on the other two armrest supports 20 respectively, each limiting device 40 comprises a limiting socket 41 arranged on the armrest support 20 and a plug rod 42 slidingly arranged in the limiting socket 41. When the backrest assembly 30 is arranged on the base support 10, the limiting hole 32 and the limiting device 40 correspond to each other, and the plug rod 42 is arranged in the limiting hole 32, so that the position of the backrest assembly 30 on the base support 10 is limited. It can be seen that the sofa with the turnover structure realizes the folding of the backrest, saves the transportation space, and reduces the difficulty of carrying.

[0032] The above is only the preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement in the spirit of the utility model is covered in the claim range of the utility model.
