The adjusting mechanism is arranged between the two first mounting plates 3, through which, users can easily adjust the height and angle of the supporting mechanism, and place articles on the bearing plate 8.

In addition, a folding mechanism is established. The folding mechanism is arranged between the first mounting plate 3 and the right armrest 2, through which users can easily adjust the size of the sofa and fold it up when it is not used to save the space.

Specifically, the adjusting mechanism comprises the two rectangular grooves 12 and the two third fixing plates 23. The two rectangular grooves 12 are respectively opened in the surfaces of the two first mounting plates 3, and the two third fixing plates 23 are respectively fixed on one side of the two first mounting plates 3. The fixed shaft 24 is fixed on one side of each third fixing plate 23, and the first rotating rod 25 is rotatably connected to the outer wall of the fixed shaft 24. The second fixing plate 22 is rotatably connected respectively to the other ends of the two first rotating rods 25, and the first fixing plate 21 is fixed respectively on the surfaces of the two second fixing plates 22. The first supporting frame 13 of the same frame type is fixedly arranged between the two first fixing plates 21. In order to achieve the function of adjustment, the second rotating rod 26 is rotatably connected respectively to one side of the two third fixing plates 23, and the spring 27 is fixedly arranged between the second rotating rod 26 and the fixed shaft 24. When the first rotating rod 25 is rotated, the second rotating rod 26 presses against the second fixing plate 22 under the effect of the spring 27, so that the angle and position of the supporting frame 13 can be adjusted.

The folding mechanism comprises the two limiting bases 32 and the third mounting plate 9. The two limiting bases 32 are fixed respectively on one side of one of the first mounting plates 3 and the right armrest 2, and the third mounting plate 9 is arranged on one side of the mounting rod 11. The second mounting frame 29 is fixedly arranged at the bottom of the third mounting plate 9 on its one side, and the four first rollers 30 are arranged at the bottom of the second mounting frame 29, which facilitates the movement and folding. The second rollers 31 are arranged on the outer walls of the second mounting frame 29 on its both sides, which further enhances the movement. On the inner walls of the second mounting frame 29 on its both sides, the first movable rod 33 is rotatably connected to the second movable rod 34, and the third movable rod 35 is rotatably connected between them. The fourth fixing plate 36 is rotatably connected to the top end of the third movable rod 35, and the fourth movable rod 38 is rotatably connected between the fourth fixing plate 36 and the second mounting frame 29. The same second supporting frame 37 is fixedly arranged between the two fourth fixing plates 36. In order to achieve stable folding and unfolding, the positioning block 39 is fixedly arranged on the inner walls of the second mounting frame 29 on its both sides, and the positioning groove 40 fitting with the positioning block 39 is opened in the surface of the two first movable rods 33.

In order to support the cushions of the sofa, several supporting mechanisms are arranged. The supporting mechanisms are all arranged between the left armrest 1 and the right armrest 2, a plurality of bed boards 41 are used for supporting, and the two third Velcro tapes 42 are fixed between the plurality of bed boards 41 to enhance stability. The fourth Velcro tapes 43 are arranged on bottom both ends of the bed board 41, which fit with the second Velcro tapes 14 arranged on the surfaces of the first supporting frame 13, the second supporting frame 37, the first mounting frame 7 and the mounting rod 11, and the corresponding Velcro tapes are arranged on the bottom of the cushions, so that the cushions can be quickly installed and disassembled.

Embodiment 2

The connector body 17 is used to design the connectors, on one side of which the two mounting holes 18 are formed, on the other side of which the two mounting grooves 20 are formed, and bolts are arranged in the two mounting holes 18 and the two mounting grooves 20 to firmly connect with other parts. At the same time, the supporting feet 16 are threadedly connected to the bottoms of the left armrest 1, the right armrest 2 and the two first mounting plates 3, and additional supporting feet 16 can be installed through the mounting pipe 19 to stably support the whole structure of the sofa.

In order to enhance the practicability of the sofa, the first annular groove 45 is opened in the surface of the first mounting base 44, in which the annular adjusting plate 46 is rotatably connected. A plurality of teeth 47 are integrally formed on the bottom of the annular adjusting plate 46, meshed with the gears 49 at the end of the two symmetrically arranged screw rods 48 that are threaded through the inner wall of the placing groove 57, the two positioning rods 51 are fixedly arranged respectively on one side of the two clamping plates 50, and all the four positioning rods 51 slide through the first annular groove 45 playing a good limiting role. By turning the annular adjusting plate 16, the clamping plates 50 can be driven to clamp articles such as cups, and prevent them from overturning.

In addition, to protect the USB port 55 and prevent dust from entering, the second annular groove 53 is formed on one side of the second mounting base 52, in which the protective cover 54 is threadedly connected. When the USB port 55 needs to be used, the protective cover 54 can be easily unscrewed; when not in use, the protective cover 54 can be closed to protect the USB port 55.

Finally, to facilitate users to move and handle the sofa, the two symmetrically arranged handles 28 are fixed on the surface of the bearing plate 8. Users can easily move the sofa by grasping the handles 28, which improves the convenience of use.
