[0021] 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.

[0022] Please see Figure 1-5 This embodiment provides a technical solution: a multifunctional sofa chair, including a base box 6, a sliding support frame 7 is provided on the upper side of the base box 6, a slide rail 13 is connected between the sliding support frame 7 and the base box 6, a nylon roller 11 is installed on the lower end of one side of the sliding support frame 7, a top plate 18 is installed on the lower side of the sliding support frame 7, a fixing pin plate 15 is installed on the lower side of the top plate 18, a slide groove 20 is provided between the fixing pin plates 15, a rotating groove 19 is provided on the upper side of the center part of the slide groove 20, a rotating pin 16 is provided in the slide groove 20, and a rotating handle 17 is provided on the upper end of the rotating pin 16.

[0023] like Figure 1-5As shown, when the sofa chair needs to be unfolded into a reclining position, rotating the rotating pin 16 causes it to rotate 90 degrees, thereby rotating the rotating handle 17 at the upper end of the rotating pin 16 to the position corresponding to the slide groove 20. This allows the sliding support frame 7 to move away from the base box 6 via the slide rail 13, thus unfolding the backrest frame 10 and the folding backrest frame 9 into a reclining position, making it convenient for users to lie down and rest. When the sofa chair needs to be folded, the sliding support frame 7 is moved along the slide rail 13 towards the base box 6. Once the sliding support frame 7 is in place, rotating the rotating pin 16 90 degrees causes the rotating handle 17 at the upper end of the rotating pin 16 to rotate into the inner side of the rotating groove 19, thereby locking the rotating handle 17 into the inner side of the fixing pin plate 15 to prevent the sliding support frame 7 from moving. Then, the seat cushion 3 is flipped upwards towards the backrest cushion 2, allowing the seat cushion 3 to... Under the action of spring 14, the backrest cushion 2 is folded to one side. The fixing pin plate 15 and the top plate 18 are both fixed on the sliding support frame 7. The rotating pin 16 is installed on the base box 6. After rotation, the rotating pin 16 and the rotating handle 17 are aligned in the groove 20 of the fixing pin plate 15. The width of the rotating handle 17 is the same as that of the groove 20. The rotating handle 17 is in the direction of the groove 20, so that when the sliding support frame 7 slides, the rotating handle 17 at the upper end of the rotating pin 16 will not be stuck in the groove 20. When it is necessary to lock the sliding support frame 7 with the rotating handle 17, the sliding support frame 7 moves into place through the slide rail 13. At this time, the rotating handle 17 at the upper end of the rotating pin 16 is in the rotating groove 19. Then the rotating handle 17 is rotated ninety degrees so that the rotating handle 17 is at ninety degrees with the groove 20, thereby allowing the rotating handle 17 to limit and fix the fixing pin plate 15, preventing the sliding support frame 7 from moving.

[0024] A seat plate 8 is installed on the upper side of the sliding support frame 7, and a seat cushion 3 is installed on the upper side of the seat plate 8. A backrest frame 10 is connected to the other side of the sliding support frame 7 via a hinge.

[0025] A backrest panel 12 is installed on the side of the backrest frame 10. A seat cushion 3 is provided on the side of the backrest panel 12 away from the backrest frame 10. A headrest 4 is provided on the upper side of the backrest cushion 2.

[0026] A folding backrest 9 is connected to the upper side of the backrest frame 10 via a hinge. A folding back panel 5 is installed on the side of the folding backrest 9 away from the backrest frame 10. A folding back pad 1 is installed on the side of the folding back panel 5 away from the folding backrest 9.

[0027] Two gas springs 14 connect the sliding support frame 7 to the base box 6, and a hinge plate connects the lower corner of the folding back frame 9 to the base box 6.

[0028] The backrest frame 10 and the sliding support frame 7 are rotatably connected by hinge plates at both ends. The sliding support frame 7 and the nylon roller 11 are connected by bearings.

[0029] Both ends of the gas spring 14 are connected to the sliding support frame 7 and the base box 6 via ball joints.

[0030] The working principle of the multifunctional sofa chair provided by this utility model is as follows: Figures 1-5 As shown, when the sofa chair needs to be unfolded into a reclining position, rotating the rotating pin 16 causes it to rotate 90 degrees, thereby rotating the rotating handle 17 at the upper end of the rotating pin 16 to the position corresponding to the slide groove 20. This allows the sliding support frame 7 to move away from the base box 6 via the slide rail 13, thus unfolding the backrest frame 10 and the folding backrest frame 9 into a reclining position, making it convenient for users to lie down and rest. When the sofa chair needs to be folded, the sliding support frame 7 is moved along the slide rail 13 towards the base box 6. Once the sliding support frame 7 is in place, rotating the rotating pin 16 90 degrees causes the rotating handle 17 at the upper end of the rotating pin 16 to rotate into the inner side of the rotating groove 19, thereby locking the rotating handle 17 into the inner side of the fixing pin plate 15 to prevent the sliding support frame 7 from moving. Then, the seat cushion 3 is flipped upwards towards the backrest cushion 2, allowing the seat cushion 3 to... Under the action of spring 14, the backrest cushion 2 is folded to one side. The fixing pin plate 15 and the top plate 18 are both fixed on the sliding support frame 7. The rotating pin 16 is installed on the base box 6. After rotation, the rotating pin 16 and the rotating handle 17 are aligned in the groove 20 of the fixing pin plate 15. The width of the rotating handle 17 is the same as that of the groove 20. The rotating handle 17 is in the direction of the groove 20, so that when the sliding support frame 7 slides, the rotating handle 17 at the upper end of the rotating pin 16 will not be stuck in the groove 20. When it is necessary to lock the sliding support frame 7 with the rotating handle 17, the sliding support frame 7 moves into place through the slide rail 13. At this time, the rotating handle 17 at the upper end of the rotating pin 16 is in the rotating groove 19. Then the rotating handle 17 is rotated ninety degrees so that the rotating handle 17 is at ninety degrees with the groove 20, thereby allowing the rotating handle 17 to limit and fix the fixing pin plate 15, preventing the sliding support frame 7 from moving.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
