[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-5 A variable double sofa includes a passenger frame 1 and a support frame 2. Both ends of one side of the support frame 2 are fixedly connected to the locking blocks 3. The support frame 2 is connected to the edge of the passenger frame 1 by the locking blocks 3. A passenger tray 4 is fixedly connected to the inside of the passenger frame 1. Both ends of the bottom of the passenger frame 1 are fixedly connected to the stabilizing legs 5. Both ends of the other side of the support frame 2 are fixedly connected to the extension frame 6. A backrest assembly 7 is provided between the extension frame 6 and the support frame 2.

[0027] In detail, the inside of the card block 3 is provided with a quick-release slot, and the width of the quick-release slot is adapted to the edge width of the manned frame 1. By using the quick-release slot, during assembly, the quick-release slot is first aligned with the edge of the manned frame 1, and then the card block 3 is pushed to lock the card block 3 onto the manned frame 1, which effectively ensures the assembly efficiency of the card block 3 and the manned frame 1.

[0028] Furthermore, both ends of the bottom of the stabilizing support leg 5 are connected to support feet by screws. The bottom of the support feet is equipped with anti-slip pads. The support feet can improve the overall friction with the ground and prevent uncontrollable displacement of the manned frame 1 during use.

[0029] Example 2:

[0030] Please see Figure 1-5 This embodiment provides a technical solution based on embodiment one: the backrest assembly 7 includes a support shaft 8, a back support plate 9, a positioning shaft 10, a positioning seat 11, a storage tube 12, and a limiting tube 13. The support shaft 8 is fixedly connected to both ends of the top of the support frame 2. The back support plate 9 is rotatably connected to the outer side of the support shaft 8. The positioning shaft 10 is rotatably connected to the end of the extension frame 6 away from the support frame 2. The positioning seat 11 is fixedly connected to the outer side of the positioning shaft 10. The storage tube 12 is fixedly connected to the top of the positioning seat 11. The limiting tube 13 is fixedly connected to the end of the storage tube 12 away from the positioning seat 11.

[0031] In detail, multiple reinforcing strips are fixedly connected between the two back support plates 9, and the reinforcing strips are hollow structures. By using the reinforcing strips, they can work with the back support plates 9 to form support for the back of the person and strengthen the overall structural strength of the back support plates 9.

[0032] The backrest assembly 7 also includes a displacement slide rod 14, a compression plate 15, a coil spring 16, an anti-slip cylinder 17, and a transmission screw 18. The displacement slide rod 14 is slidably connected to the middle of the limiting cylinder 13, and one end of the displacement slide rod 14 is rotatably connected to the back support plate 9. The compression plate 15 is fixedly connected to one end of the displacement slide rod 14 inside the storage cylinder 12. The coil spring 16 is fixedly connected between the bottom end of the compression plate 15 and the bottom end inside the storage cylinder 12. The anti-slip cylinder 17 is fixedly connected to one side of the limiting cylinder 13. The transmission screw 18 is threadedly connected to the middle of the anti-slip cylinder 17. The contact pad 19 is fixedly connected to one end of the transmission screw 18 inside the anti-slip cylinder 17.

[0033] Preferably, the back support plate 9 is fixedly connected to the side near the displacement slide rod 14 with an assembly ear. The assembly ear has a rotating shaft inside. The end of the displacement slide rod 14 located outside the storage tube 12 is fixedly connected to an assembly ring. The displacement slide rod 14 is connected to the rotating shaft through the assembly ring. By using the assembly ring and the rotating shaft, the displacement slide rod 14 can be stably assembled with the back support plate 9, ensuring the connection effect between the displacement slide rod 14 and the back support plate 9.

[0034] Here, a knob is fixedly connected to one end of the transmission screw 18 outside the anti-slip cylinder 17, and anti-slip textures are provided on the outer side of the knob and one side of the contact pad 19. The knob allows personnel to easily rotate the transmission screw 18, thereby ensuring the transmission efficiency of the transmission screw 18. In addition, the anti-slip textures on the contact pad 19 can improve the friction between the contact pad 19 and the displacement slide bar 14.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] The working principle is as follows: First, a seat cushion is laid flat on the person-carrying tray 4. Then, according to the needs of use, the support frame 2 is moved to a designated position on the edge of the person-carrying frame 1, and the locking block 3 is aligned with the edge of the person-carrying frame 1. Then, the support frame 2 is pushed, and the back support plate 9 is snapped into place on the person-carrying frame 1 with the help of the locking block 3. This greatly reduces the limitations of the overall application.

[0037] Furthermore, during the use of the back support plate 9, the transmission screw 18 can be rotated. In conjunction with the connection between the transmission screw 18 and the anti-slip cylinder 17, the transmission screw 18 can drive the contact pad 19 away from the displacement slide rod 14, thereby reducing the friction when the displacement slide rod 14 slides, and pulling the back support plate 9, causing the back support plate 9 to rotate under the support of the support shaft rod 8, thereby adjusting the tilt angle of the back support plate 9. At the same time, during the flipping process of the back support plate 9, the displacement slide rod 14 can slide at the limiting cylinder 13 to push the extrusion plate 15, causing it to move inside the storage cylinder 12 and extrude the spiral spring 16. After the back support plate 9 is adjusted, the transmission screw 18 is rotated to make the contact pad 19 and the displacement slide rod 14 fit tightly together, so that the displacement slide rod 14 cannot slide at the limiting cylinder 13, thereby locking the position of the back support plate 9.

[0038] When the subsequent contact pad 19 disengages from the displacement slide bar 14 again, the helical spring 16 loses its limit and can then push the compression plate 15, thereby driving the back support plate 9 to reset.
