[0030] Example 1

[0031] See also Figure 1-Figure 3 This embodiment provides a single sofa frame to solve the problem that the inclination angle of the seat frame of the existing sofa frame is difficult to adjust.

[0032] In this embodiment, the single sofa frame includes an armrest frame 20 fixedly connected to the back panel frame 10, a support beam 40 is fixedly connected between the armrest frame 20 and the back panel frame 10, the front end of the support beam 40 is hinged to the seat panel frame 30, a rotatable adjustment rod 41 is provided inside the support beam 40, a slider 42 is screwed on the adjustment rod 41, a guide groove 32 is provided on the side rod 31 of the seat panel frame 30 and is arranged obliquely relative to the axis of the side rod 31, and a limit rod 43 on the slider 42 is slidably engaged with the guide groove 32.

[0033] In this embodiment, the slider 42 is driven to slide inside the support beam 40 by rotating the adjustment rod 41, and the sliding engagement of the limit rod 43 and the guide groove 32 can drive the seat frame 30 to swing as a whole, thereby achieving the purpose of adjusting the inclination angle of the seat frame 30, which can meet the diverse needs of users and enhance the user experience.

[0034] It should be noted that the armrest frame 20 and the backboard frame 10 are fixedly connected to form an integrated structure, and legs are fixedly connected to the bases of the armrest frame 20 and the backboard frame 10. The armrest frame 20 is constructed as an L-shape as a whole, and the support beam 40 is fixedly connected between the armrest frame 20 and the backboard frame 10, and the support beam 40 and the armrest frame 20 are placed in the same plane. As an example, the support beam 40 is kept horizontally arranged as a whole, and the support beam 40 defines an inner cavity with a rectangular cross-section. The adjusting rod 41 is rotatably arranged in the inner cavity of the support beam 40 as a whole, and the adjusting rod 41 is arranged along the longitudinal direction of the support beam 40 as a whole, that is, the adjusting rod 41 is kept horizontally arranged as a whole, and the slider 42 is screwed on the outside of the adjusting rod 41, and the slider 42 is adaptively clamped in the inner cavity of the support beam 40 in shape, and the rotation of the adjusting rod 41 is used to drive the slider 41 to slide in the inner cavity of the support beam 40.

[0035] In addition, the limit rod 43 is fixedly connected to the slider 41, and the limit rod 43 and the adjusting rod 41 are arranged vertically, and the limit rod 43 as a whole is arranged horizontally. An avoidance groove for the limit rod 43 to extend is opened on the inner wall of the support beam 40. As an example, the avoidance groove is constructed as a long straight groove structure that is parallel to the adjusting rod 41.

[0036] In addition, the seat plate frame 30 is constructed as a whole in a U-shape, and the seat plate frame 30 has two side rods 31 arranged parallel to each other, and the ends of the side rods 31 are hinged to the front end of the support beam 40 (i.e., one end close to the armrest frame 20), and the guide groove 32 is arranged at the rear end of the side rod 31 (i.e., one end close to the back plate frame 10), and the guide groove 32 is arranged obliquely relative to the axis of the side rod 31, and the guide groove 32 extends along the curved circumferential surface of the side rod 31.

[0037] It should also be noted that when the seat plate frame 30 is in a horizontal state as a whole, the side rod 31 is parallel to the support beam 40. At this time, the guide groove 32 is arranged crosswise with the support beam 40 as a whole. When the slider 42 slides along the support beam 40 driven by the adjusting rod 41, the limiting rod 43 slides along the axial direction of the adjusting rod 41 as a whole. By utilizing the sliding engagement between the limiting rod 43 and the guide groove 32, the limiting rod 43 will push the side rod 31 to swing, thereby changing the inclination angle of the seat plate frame 30.

[0038] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
