The four metal sliding sleeves 4 are fixedly connected to the inside of the sofa cushion 3. The four sliding rods 5 are slidably connected to the inside of the four metal sliding sleeves 4. The four threaded sleeves 6 are fixedly connected to the surface of the four metal sliding sleeves 4. Two round hole slots 7 are opened on both sides of the sofa cushion 3. The four threaded sleeves 6 are fixedly connected to the inside of the four round hole slots 7. The four long bolts 8 are threadedly connected to the inside of the four threaded sleeves 6. The four long bolts 8 are rotatably installed inside the four round hole slots 7. Two fixing holes 9 are opened on the surface of each of the four sliding rods 5. The end of the long bolt 8 near the sliding rod 5 is slidably engaged in the inside of the fixing hole 9.

[0025] When people need to unfold the sofa to use as a bed, they can rotate the sofa cushion 3 using the hinges, causing it to rotate to the rear end of the sofa base frame 1. Finally, they can rotate the long bolt 8 using a wrench. The long bolt 8 rotates and, through its connection with the threaded sleeve 6, gradually moves out of the lower fixing hole 9. At this time, the slide rod 5 slides downwards and out of the metal sliding sleeve 4 due to its own gravity. People can then rotate the long bolt 8 again using a wrench, causing it to move and re-engage into the upper fixing hole 9. At this point, the slide rod 5 can be fixedly installed inside the metal sliding sleeve 4 using the long bolt 8. The four slide rods 5 support the sofa cushion 3 on the ground, ensuring its stability when installed at the rear of the sofa base frame 1, thus completing the unfolding of the sofa cushion 3.

[0026] A front baffle 10 is rotatably mounted on the front side of the sofa base frame 1. Two fixing bolts 11 are mounted on the front sides of the two side baffles 2. The two fixing bolts 11 are respectively installed at the left and right ends of the front baffle 10. Two mounting grooves 12 are opened on the surface of the front baffle 10. Support plates 13 are rotatably mounted inside the two mounting grooves 12. Rotating shafts 14 are fixedly sleeved on the surface of the two support plates 13.

The lower ends of the two screws 16 are slidably engaged inside the two mounting holes 17 on the front side.

[0027] Finally, by using a wrench to rotate the two fixing bolts 11, the two fixing bolts 11 are moved out of the front baffle 10, thereby releasing the fixing effect on the front baffle 10. By using a wrench to rotate the screw 16 and move it out of the mounting hole 17, the front baffle 10 can be rotated 90 degrees, so that the front baffle 10 and the sofa base frame 1 are on the same horizontal plane. By rotating the support plate 13 90 degrees and moving it out of the mounting groove 12, the support plate 13 is now supported on the ground. Finally, by using a wrench to rotate the screw 16 again and make it snap into the other mounting hole 17, the process is complete. With the pair of support plates 13 fixed, people can support the front panel 10 in the same way. At this time, the front panel 10, the sofa base frame 1, and the sofa cushion 3 can form a bed structure. When guests come to the house and there are not enough beds, it is convenient for guests to lie on the sofa to sleep. People can rotate the front panel 10 to a horizontal position with the sofa base frame 1 for guests to lie down. The sofa cushion 3 can also be flipped to the rear position of the sofa base frame 1, thereby increasing the sofa lying area, improving the comfort of guests, and enhancing the practicality of the sofa.
