[0028] The embodiments of the present application provide a sofa with an angle adjustment structure, thereby solving the problem that the backrest of the current sofa is usually an integrated setting, and when adjusting the angle, multiple groups of backrests will move synchronously, which is not convenient for individual adjustment according to the needs of different users of the sofa.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The embodiment of the utility model discloses a sofa with an angle adjustment structure.

[0031] According to the attached Figure 1-5 As shown, a sofa with an angle adjustment structure includes a sofa body 1 and a sofa backrest 101, an adjustment mechanism 2 is arranged between the sofa body 1 and the sofa backrest 101, and the adjustment mechanism 2 includes:

[0032] An inner panel 201, which is arranged inside the sofa backrest 101;

[0033] A shaft 4, which is arranged inside the sofa body 1, and the shaft 4 is used to rotate the inner plate 201;

[0034] A first electric telescopic rod 3, which is fixedly connected to the inside of the sofa body 1, and the first electric telescopic rod 3 is used to move the inner plate 201;

[0035] The square piece 601 is arranged on the side wall of the shaft rod 4 , and is used to fix the shaft rod 4 .

[0036] The inner plate 201 is rotatably connected to the outer peripheral wall of the shaft rod 4 , and the bottom of the inner plate 201 is fixedly connected to the bottom plate 202 .

[0037] A slide groove 203 is provided on the side wall of the bottom plate 202, and a connecting piece 301 is slidably connected inside the slide groove 203. The end of the first electric telescopic rod 3 is rotatably connected to the connecting piece 301. The connecting piece 301 can be driven by the first electric telescopic rod 3 to move. At the same time, the connecting piece 301 will push the inner plate 201 to rotate on the outer peripheral wall of the shaft 4. At this time, the angle of each set of sofa backrests 101 can be adjusted individually.

[0038] The adjustment mechanism 2 also includes:

[0039] A clamping strip 401 is provided on the side wall of the shaft 4 and is used to fix the inner plate 201;

[0040] The inner rod 6 is slidably connected to the inside of the shaft rod 4 , and the inner rod 6 is used to move the clamping strip 401 .

[0041] A square groove 402 is formed on both the upper and lower sides of the shaft rod 4 , and the clamping strip 401 is slidably connected inside the square groove 402 . A clamping groove 204 is formed on the inner wall of the inner plate 201 , and the clamping strip 401 is clamped inside the clamping groove 204 .

[0042] The shaft 4 is rotatably connected to the inside of the sofa body 1, the square piece 601 is fixedly connected to the end of the inner rod 6, the square piece 601 passes through the end of the shaft 4, the square piece 601 is inserted into the inside of the sofa body 1, and a second electric telescopic rod 602 is fixedly connected between the square piece 601 and the sofa body 1. First, the square piece 601 and the inner rod 6 can be pushed to the inside of the shaft 4 by the driving of the second electric telescopic rod 602. At this time, the square piece 601 will be separated from the square mouth of the sofa body 1. At this time, the shaft 4 will be rotatably connected to the inside of the sofa body 1. Secondly, the extrusion rod 603 on the inner rod 6 will be pushed between the two groups of card strips 401, and the card strip 401 will be squeezed to slide out of the square groove 402. At this time, the card strip 401 will be inserted into the card groove 204 on the inner plate 201, and the shaft 4 and the inner plate 201 are fixed. Finally, by driving the first electric telescopic rod 3 on the three groups of inner plates 201, the angles of the three groups of sofa backrests 101 can be adjusted simultaneously and synchronously.

Springs 5 ​​are fixedly connected between the clamping strips 401. The springs 5 ​​are used to reset the clamping strips 401. When the extrusion rods 603 are moved out from between the two groups of clamping strips 401, the clamping strips 401 can be contracted inside the square groove 402 through the pulling force of the springs 5.

[0044] When the utility model is in use, when the angles of the three groups of sofa backrests 101 are adjusted synchronously, the square piece 601 and the inner rod 6 are first pushed to the inside of the shaft rod 4 by the driving of the second electric telescopic rod 602, and the square piece 601 will shrink inside the shaft rod 4, and then the extrusion rod 603 on the inner rod 6 will be pushed between the two groups of card strips 401, and the card strips 401 will be squeezed to be inserted into the card slots 204 on the inner plate 201, so that the shaft rod 4 and the inner plate 201 can be fixed. The movable telescopic rod 3 drives the shaft rod 4 to rotate inside the sofa body 1 for adjustment; when adjusting the angle of each set of sofa backrests 101 individually, the second electric telescopic rod 602 drives the square piece 601 and the inner rod 6 to move outward until the square piece 601 is plugged into the square opening inside the sofa body 1 for fixation, and at the same time, the clamping strip 401 is contracted inside the square groove 402 by the pulling force of the spring 5. At this time, the first electric telescopic rod 3 can sequentially drive the inner plate 201 to rotate on the surface of the shaft rod 4 to adjust the sofa backrest 101.
