[0018] Figure 3 This is a schematic diagram of the structure of the connection framework of an embodiment of the present application. DETAILED DESCRIPTION

[0019] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0020] like Figures 1 to 3As shown, a sofa frame with an adjustable backrest described in the utility model comprises an armrest frame 1 symmetrically arranged on both sides, the armrest frame 1 comprises a U-shaped main frame 1-1, and two upper and lower cross braces 1-2 are horizontally arranged in the U-shaped main frame 1-1, wherein a support rod 1-3 is vertically arranged between the upper cross brace 1-2 and the U-shaped main frame 1-1 to ensure the structural strength of the entire armrest frame 1; a supporting leg 2 is arranged at the bottom end of the armrest frame 1; the two armrest frames 1 are connected by a connecting frame 3, and two connecting frames 3 are arranged, which are distributed on the front and rear sides of the two armrest frames 1. In a normal state, the backrest frame 4 contacts with the top of the connecting frame 3 located at the rear side so that The connecting frame 3 is used to provide support for the backrest frame 4 to ensure safety; an adjustment seat 5 is provided on the inner side of the armrest frame 1, and a plurality of slots 6 are provided on the adjustment seat 5; the backrest frame 4 is movably provided in the slots 6, and the inclination state of the backrest frame 4 can be adjusted by adjusting the backrest frame 4 in different slots 6 to meet different needs of users; an adjustment frame 7 is movably connected to one end of the backrest frame 4, and the end of the adjustment frame 7 away from the backrest frame 4 is movably connected to the connecting frame 3, and the adjustment frame 7 can realize the indirect connection between the backrest frame 4 and the armrest frame 1, thereby enhancing the integrity of the entire sofa frame, providing auxiliary support for the backrest frame 4, and ensuring safety in use. The movable connection of the adjustment frame 7 between the connecting frame 3 and the backrest frame 4 can ensure that the adjustment of the backrest frame 4 is not affected.

[0021] Furthermore, the connecting frame 3 in this embodiment is a rectangular structure, which is fixed between the two handrail frames 1 by bolts; in addition, the connecting frame 3 at the front end is provided with a hinged ear plate, and the adjustment frame 7 is hingedly connected to the connecting frame 3 through the ear plate.

[0022] Furthermore, the adjustment frame 7 is a rectangular structure, and is provided with slide grooves 8 on both sides close to the backrest frame 4. A slide rod 9 is provided on the backrest frame 4, and the slide rod 9 slides in the slide groove 8; when the backrest frame 4 needs to be switched between different slots 6, the slide rod 9 will slide in the slide groove 8 to ensure the normal adjustment of the backrest frame 4. At the same time, such a setting also helps the backrest frame 4 to contact with the rear connecting frame 3 after each adjustment, thereby realizing the support of the connecting frame 3 for the backrest frame 4, thereby ensuring safety.

[0023] Further, a rectangular support frame 10 is provided at the bottom of the connecting frame 3, and the support frame 10 is a rectangular structure. The support frame 10 is fixed between the two connecting frames 3 by bolts, and the adjustment seat 5 is fixedly arranged on the inner side of the support frame 10. The arrangement of the support frame 10 can further enhance the structural strength of the entire sofa frame and improve safety. Preferably, in this embodiment, the slot 6 on the adjustment seat 5 is an arc structure, and the baffles on both sides of the slot 6 are arc structures facing the same direction, and the baffles are all arranged in an arc shape toward the backrest frame 4, which can limit the bottom of the backrest frame 4 placed in the slot 6 to prevent the backrest frame 4 from tilting from the slot 6 after being stressed. Among them, in this embodiment, the backrest frame 4 is a rectangular structure made of round rods, so that the supporting round rods at the bottom of the backrest frame 4 can better fit the arc slot 6. In addition, a support rod 11 is provided at one end of the backrest frame 4 close to the adjustment frame 7 to enhance the structural strength of the backrest frame 4 and ensure its stability when stressed.

[0024] When the utility model is in use, when the state of the backrest frame 4 needs to be adjusted, it only needs to adjust the backrest frame 4 and switch the bottom round rod thereof in different slots 6. The utility model has the advantages of easy operation, simple structure, high safety and strong practicality.
