The first threaded rod 14 passes through the slot of the round sleeve 15, and nuts 16 are provided on both sides of the round sleeve 15. The nuts 16 are threadedly connected to the first threaded rod 14, so that the first threaded rod 14 is stably installed on the round sleeve 15, so that when a person sits on it, he can stably lean against the back plate 1.

[0032] Two first limiting slide grooves 5 are provided on the back side of the back plate 1, and the two first limiting slide grooves 5 are symmetrically arranged along the back side of the back plate 1. A push-pull plate 6 is slidably connected in the first limiting slide groove 5, and the push-pull plate 6 can be stretched outward relative to the back plate 1.

[0033] A transverse groove 17 is provided on the back side of the push-pull plate 6. The transverse groove 17 is connected to a limiting slide plate 18 through a second limiting slide groove 23. Side plates 20 are fixedly connected to both sides of the back of the limiting slide plate 18. A third rotating column 21 is rotatably connected between the two side plates 20. A mounting plate 22 is fixedly connected to the outer wall of the third rotating column 21. A threaded sleeve 24 is fixedly connected to one end of the mounting plate 22. A third threaded rod 25 is threadedly connected to the inner thread of the threaded sleeve 24. A support plate 26 is fixedly connected to the end of the third threaded rod 25 away from the threaded sleeve 24.

[0034] Example 2: Based on Example 1, a technical means is added to facilitate the storage of the threaded sleeve 24, the third threaded rod 25, and the support plate 26.

[0035] Key reference Figure 2-5 This embodiment also includes a first magnet 27 and a second magnet 28.

[0036] Two vertical grooves 11 are provided on the push-pull plate 6. The vertical grooves 11 are perpendicular to the horizontal grooves 17. A first magnet 27 is fixedly installed on the outer wall of the support plate 26. A second magnet 28 is installed in the vertical grooves 11. The first magnet 27 can be attracted and fixed to the second magnet 28.

[0037] The other features of Example 2 are the same as those of Example 1.

[0038] Example 3: Based on Example 2, a technical means was added to facilitate the storage of the threaded sleeve 24, the third threaded rod 25, and the support plate 26.

[0039] Key reference Figure 2-5 A second threaded rod 19 is rotatably connected within the transverse groove 17, and the second threaded rod 19 is perpendicular to the vertical groove 11. A limiting slide plate 18 is threadedly connected to the outer wall of the second threaded rod 19. A first rotating column 9 is rotatably connected to the upper limit of the push-pull plate 6. The first rotating column 9 is fixedly connected to one end of the second threaded rod 19. A rotating wheel 8 is fixedly installed on the outer wall of the first rotating column 9. Two second baffles 10 are fixedly connected to the push-pull plate 6 and are placed on both sides of the transverse groove 17. The rotating mounting plate 22 can press against the second baffles 10. The vertical groove 11 and the second baffles 10 are not on the same longitudinal plane, so that when the mounting plate 22 is stored in the vertical groove 11, it will not press against the second baffles 10.

[0040] The first baffle 7 is fixedly installed on both sides of the push-pull plate 6. The rotating wheel 8 and the first rotating column 9 are placed behind the first baffle 7 to prevent the person lying on it from being squeezed by the rotating wheel 8 and the first rotating column 9.

[0041] The other features of Example 3 are the same as those of Example 2.

[0042] In practice, each component is installed first. The back panel 1, armrest panel 2, seat panel 3, and support leg 4 are separate components, while the push-pull panel 6 and its components are a separate component, which makes it easy to carry and install for customers.

[0043] After the above components are installed, when it is necessary to make the device into an office chair, loosen the nut 16 and rotate the back panel 1 so that the back panel 1 and the seat panel 3 cooperate to form an office chair. Then tighten the nut 16 to make the device into an office chair.

[0044] When the device needs to function as a sofa, loosen nut 16 and rotate back panel 1, then pull push-pull plate 6 outward. Note that the sliding of push-pull plate 6 and first limiting groove 5 has sufficient friction, i.e., rubber pads are provided on both the first limiting groove 5 and the push-pull plate 6, so that when push-pull plate 6 slides out relative to the first limiting groove 5, it will not fall directly back into the first limiting groove 5 under the action of gravity. At this time, adjust the tilt angle of back panel 1 and push-pull plate 6 as needed, so that threaded sleeve 24, third threaded rod 25, and support plate 26 are removed from vertical groove 11, and the third threaded rod 25 is rotated to change the overall length of threaded sleeve 24 and third threaded rod 25 to the required length. Then, press support plate 26 onto the ground, and the device is now a sofa that can be reclined.

[0045] When the device needs to be used as a bed, loosen nut 16 and rotate back plate 1, then pull push plate 6 outward. At this point, the angles of back plate 1, push plate 6, and seat plate 3 should be almost parallel. First, remove threaded sleeve 24, third threaded rod 25, and support plate 26 from vertical slot 11, and rotate third threaded rod 25 to change the overall length of threaded sleeve 24 and third threaded rod 25 to the required length. Then, press support plate 26 onto the ground; at this point, the device is a bed.

[0046] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
