DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] like Figure 1 to Figure 2 As shown, a detachable sofa comprises a backrest 1 and a seat frame 2, the backrest 1 is arranged above the seat frame 2, and armrests 3 are arranged on both sides of the seat frame 2. The backrest 1 is detachably connected to the seat frame 2 and the armrests 3 respectively, and a storage position 4 is formed by clamping the armrests 3 on both sides with the seat frame 2 when combined; when the backrest 1 is in a connected state with the seat frame 2 and the armrests 3, the backrest 1 is located at the rear position on the seat frame 2; when the backrest 1 is disconnected from the seat frame 2 and the armrests 3, the backrest 1 can be rotated relative to the seat frame 2 and folded in the storage position 4. The detachable design of the backrest 1, the seat frame 2 and the armrests 3 can enable the sofa to be unfolded and folded. During transportation, the backrest 1 can be folded in the storage position 4 to reduce the space occupied by the sofa, so as to facilitate the transportation of the sofa.

[0027] Specifically, Figures 3 to 6 As shown, the bottom of the backrest 1 extends to form a first connecting frame 101, connecting plates 102 are arranged on both sides of the first connecting frame 101, first mounting plates 103 are arranged on both sides above the first connecting frame 101, the first mounting plate 103 is provided with a first mounting hole 1031, and a first connecting member 1032 is arranged in the first mounting hole 1031, the seat frame 2 includes a base 201, a second connecting frame 202 is arranged above the base 201, second mounting plates 203 are arranged on both sides below the second connecting frame 202, the second mounting plate 203 is provided with a second mounting hole 2031, and the second mounting hole 2031 corresponds to the first connecting member 1032, a fourth mounting hole 301 is arranged on the inner side of the armrest 3, a second connecting member 3011 is arranged in the fourth mounting hole 301, and a third mounting hole 1021 is provided on the connecting plate 102, and the third mounting hole 1021 corresponds to the second connecting member 3011.

[0028] The first connecting member 1032 and the second connecting member 3011 are both provided with internal threads. When the sofa needs to be adjusted to the unfolded state, the backrest 1 is erected on the second connecting frame 202, and the first bolt is used to pass through the gasket and the second mounting hole 2031 and is threadedly connected to the first connecting member 1032, so that the backrest 1 is fixed above the second connecting frame 202, and then the second bolt is used to pass through the gasket and the third mounting hole 1021 and is threadedly connected to the second connecting member 3011, so that the connecting plate 102 and the armrest 3 are fixed together, so that the backrest 1, the seat frame 2 and the armrest 3 are fixed, and the sofa is in the unfolded state, which is convenient for users to sit on. When the sofa needs to be adjusted to the stored state, the first bolt and the second bolt are screwed to make the backrest 1, the seat frame 2 and the armrest 3 fall off the fixed connection state, and then the backrest 1 is folded in the storage position 4, so that the backrest 1 is flattened and placed above the second connecting frame 202, so that the sofa is in the stored state, reducing the occupied space and facilitating the transportation of the sofa.

[0029] The diameter of the first mounting hole 1031 is smaller than that of the second mounting hole 2031, and the diameter of the fourth mounting hole 301 is smaller than that of the third mounting hole 1021; the purpose of the above design is that, taking the first mounting hole 1031 and the second mounting hole 2031 as an example, when there is a processing error, when there is a deviation in the alignment of the first mounting hole 1031 and the second mounting hole 2031, that is, when the center of the first mounting hole 1031 and the center of the second mounting hole 2031 are not located on the same horizontal line, the bolt can also pass through the second mounting hole 2031 and connect to the first mounting hole 1031 to complete the fixed installation; the diameter size difference between the fourth mounting hole 301 and the third mounting hole 1021 is also based on the above principle, which will not be repeated here.

[0030] When the backrest 1 is folded in the storage position 4, the back surface of the backrest 1 and the upper surface of the armrest 3 are on the same horizontal plane, which makes the sofa more beautiful and convenient to store.

[0031] After the backrest 1, the seat frame 2 and the armrest 3 are assembled, they are covered with sofa leather to form a sofa. The base 201 is hollow. Figure 3 As shown, when viewed from the bottom of the base 201 , the user can intuitively see the second mounting hole 2031 and the third mounting hole 1021 , thereby adjusting the sofa to an unfolded or folded state according to needs, which is convenient to use and simple to install.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
