[0035] Referring to Figure 2 and Figure 3The connecting assembly comprises a hanging plate 41 detachably connected to the wall body 3 on the side close to the back body 2, a connecting plate 42 fixedly connected to the hanging plate 41 on the side away from the wall body 3, and a back plate 43 fixedly connected to the back body 2 on the side close to the hanging plate 41. The connecting plate 42 has an L-shaped cross section, and a plurality of clearance openings 421 are formed in the vertical side of the connecting plate 42 and are distributed at equal intervals along the length direction of the connecting plate 42. The plurality of clearance openings 421 make the vertical side of the connecting plate 42 form a plurality of plug-in strips 422 distributed at equal intervals. A plurality of plug-in slots are formed in the bottom surface of the back plate 43 and are distributed at equal intervals. The number of the plug-in slots is consistent with and corresponds to the number of the plug-in strips 422. The plug-in strips 422 are plugged into the corresponding plug-in slots to connect the back plate 43 to the connecting plate 42.

[0036] The bottom surface of the back plate 43 and located at the opposite ends of the back plate 43 are fixedly connected with vertical rods 431. One end of the vertical rod 431 away from the back plate 43 is rotatably connected with a first limiting block 432. When the back plate 43 is connected to the connecting plate 42, the first limiting block 432 is rotated to make the top surface of the first limiting block 432 abut against the bottom surface of the horizontal side of the connecting plate 42, so as to limit the back plate 43 on the connecting plate 42.

[0037] In order to enhance the connecting strength between the connecting plate 42 and the hanging plate 41, a reinforcing rib 423 is fixedly connected between the connecting plate 42 and the hanging plate 41. The cross section of the reinforcing rib 423 is in the shape of a right triangle, and the right angle of the reinforcing rib 423 is located between the bottom surface of the horizontal side of the connecting plate 42 and the side surface of the hanging plate 41. The hanging plate 41 is detachably connected to the side surface of the wall body 3 through the expansion bolts 411. In this embodiment, a plurality of expansion bolts 411 are provided and are distributed at equal intervals on the top and bottom of the side surface of the hanging plate 41. The horizontal side of the connecting plate 42 and the reinforcing rib 423 are located between the plurality of expansion bolts 411.

[0038] Referring to Figure 3 and Figure 4The top surface of the backrest body 2 is fixedly connected with a plurality of vertical rods 21, the plurality of vertical rods 21 are distributed at equal intervals along the length direction of the backrest body 2, the top ends of the plurality of vertical rods 21 are fixedly connected with a transversely arranged horizontal rod 22, a plurality of decorative bands 23 are sewn on the circumferential side of the backrest body 2, the plurality of decorative bands 23 are distributed at equal intervals along the length direction of the backrest body 2, and the top end of the decorative band 23 is arranged around the horizontal rod 22. A plurality of through openings 433 are formed in the side of the back plate 43 close to the backrest body 2, the number of the through openings 433 is consistent with and one-to-one corresponds to the number of the decorative bands 23, and the through openings 433 are used to accommodate the corresponding decorative bands 23. In this embodiment, the horizontal rod 22 is a mirror surface metal rod; in order to increase the atmosphere, the top surface of the back plate 43 is provided with a receiving groove, the inside of the receiving groove is fixedly embedded with a lamp groove body 434 with a slot opening arranged upward, the inner bottom wall of the lamp groove body 434 is bonded with a lamp strip 435, and the slot opening of the lamp groove body 434 is clamped with a transparent lamp cover 436. Thus, the light of the lamp strip 435 is emitted through the transparent lamp cover 436 and shines on the mirror surface metal rod, thereby increasing the overall atmosphere.

[0039] With reference to Figure 1 and Figure 5 , the second base is provided with a stretching base away from the wall body 3, the stretching base is located in the inside of the second base, and the stretching base can move towards or away from the second base; when the stretching base is moved out of the inside of the second base, and one of the second seat cushions 12 is placed on the top surface of the stretching base, the second base and the stretching base form a bed body.

[0040] With reference to Figure 5 and Figure 6 , the second base comprises a side plate 5 arranged close to the wall and a plurality of fixed plates 51 vertically fixed at equal intervals on the side of the side plate 5 away from the wall body 3, and a first limiting rod 52 and a second limiting rod 53 are fixedly arranged between the plurality of fixed plates 51; the side plate 5, the first limiting rod 52 and the second limiting rod 53 are arranged in parallel with each other, and the first limiting rod 52 is adjacent to the side plate 5; the arrangement of the first limiting rod 52 and the second limiting rod 53 strengthens the connection between the plurality of fixed plates 51.

[0041] With reference to Figure 5 and Figure 6The stretching base comprises a pulling plate 6 and a plurality of sliding strips 61 which are equidistantly distributed and vertically fixed on one side of the pulling plate 6 close to the side plate 5, and a gap is present between two adjacent fixed plates 51 for the sliding strips 61 to slide and insert; the top surface of the first limiting rod 52 and the top surface of the second limiting rod 53 support the bottom surface of the sliding strip 61, and the top surface of the sliding strip 61 is flush with the top surface of the fixed plate 51. The bottom surface of each sliding strip 61 located on the end of the pulling plate 6 is fixedly connected with two support rods 611, and the two support rods 611 are respectively located at the two ends of the bottom surface of the sliding strip 61; the bottom end of each support rod 611 is provided with a universal wheel 612 with a foot brake; and the four universal wheels 612 with foot brakes are arranged to facilitate the movement of the sliding strip 61 towards or away from the side plate 5 through the pulling plate 6.

[0042] With reference to Figure 5 and Figure 6 When the sliding strip 61 is moved away from the side plate 5 through the pulling plate 6, the second limiting rod 53 limits the support rod 611, so that the stretching base cannot be separated from the inside of the second base. When the sliding strip 61 is moved towards the side plate 5 through the pulling plate 6, the first limiting rod 52 limits the support rod 611, so that the stretching base cannot continue to move towards the side plate 5.

[0043] With reference to Figure 1 When the stretching base is stored in the inside of the second base, the pulling plate 6 is located between the two fixed plates 51 on the two ends of the side plate 5; the fixed plate 51 on the end of the side plate 5 and away from the side plate 5 is threadedly connected with a limiting bolt, and a gasket is sleeved on the limiting bolt; the gasket is used to limit the pulling plate 6, so that the pulling plate 6 cannot move away from the side plate 5.

[0044] The implementation principle of the sofa bed is to realize the quick conversion between the sofa and the bed, improve the multifunctionality and convenience of the furniture, and improve the overall aesthetics and grade; the combination of the lamp strip 435 and the mirror metal rod increases the overall atmosphere and improves the aesthetics and grade of the product.

[0045] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
