Then, the pivot end extended from the back rod of theleg 21 is continuously connected to the stretchable rod of theleg 23, and the another pivot end extended from the support rod of theleg 22 is continuously connected to the transmission rod of theleg 24, the connection rod of theleg 25, the locking rod of theleg 26 and the front rod of theleg 27. In addition, a brace of theleg 28 is provided at the two pivot ends near the front rod of theleg 27, and the brace of theleg 28 is respectively pivoted to the two pivot ends, so that the whole leg structure is stretched and retracted. Since a plurality of components are successively extended forward by two pivot ends, the leg can be unfolded when the leg structure is stretched; and when the leg structure is retracted, the leg can be folded successively, so that a thin assembly can be formed after the leg structure is retracted and then stored beneath the underframe structure without occupying the space between the underframe structure and the ground. Such a compact structure can effectively save space, further provide the sofa chair frame with good breathability and ventilation after the sofa chair frame is assembled into a sofa, and reduce dust. The structure is not only elegant in appearance, but also can prolong the service life of the leg structure. - Further, the leg structure may also include an intermediate fixing rack of the
leg 29, which is located in the intermediate of the stretchable rod of theleg 23 and connected to the stretchable rod of theleg 23. An intermediate fixing rack of theleg 29 is provided in the intermediate portion of the leg structure when stretched, i.e., at the stretchable rod of theleg 23. After the leg structure is stretched, the leg structure can be provided with high load-bearing capability, and the comfort in use can be effectively improved. - Wherein, the back structure may include: a fixing rack of the back 31 mounted on the underframe structure; a rotating rack of the back 32, one end of which is connected to the fixing rack of the back 31 and the other end of which is connected to the rotating rod of the back 53; a supporting frame of the back 33, including a
back rod 331 and a leaningrod 332 which are integrated, one end of theback rod 331 being connected to the fixing rack of the back 31, the other end of theback rod 331 being connected to the rotating rack of the back 32 by a joint 34. - The back structure may be mounted on the underframe structure by the fixing rack of the back 31. First, stability of a back rest is achieved. Then, two pivot ends are extended from the two ends of the fixing rack of the back 31. The two pivot ends form a retractable enclosed structure by means of the support rack of the back 33, the joint 34 and the rotating rack of the back 32. In this way, for the back structure, the angle of the back can also be adjusted according to a user's requirements, thus manifesting the multi-functionality.
- Further, the back structure may also include a mounting rack of the back 35, one end of which is connected to the swinging
rod 54 and the other end of which is connected to the underframe structure. The back structure is further mounted between the swingingrod 54 and the underframe structure in the form of a mounting rack of the back 35, so that the angle of the back structure is adjusted within a certain range. In this way, the adjustment of the back structure is safer. - Still further, a stopping
bump 321 may be provided at an end of the rotating rack of the back 32 close to the joint 34; and the stoppingbump 321 is located inside the connection portion between the fixing rack of the back 31 and the rotating rack of the back 32. By providing a stoppingbump 321 on the rotating rack of the back 32, the support rack of the back 33 is prevented from being over inclined. Being over inclined can cause discomfort to users, especially to the elder. In this way, the sofa chair frame of the present invention is further safer and more comfortable. - Wherein, the underframe structure may include a
front beam 11 connected to the leg structure; aback beam 12 connected to the back structure; anintermediate frame 13 connected to thelinkage rod 52; and aseat mounting rack 14, two ends of which are connected to the leg structure and the back structure, respectively. The underframe structure mainly consists of thefront beam 11, theback beam 12, theintermediate frame 13 and theseat mounting rack 14. The underframe structure is mainly used to bear the major sofa structure. Further, the underframe structure also includes: atension spring 15, one end of which is connected to theback beam 12 and the other end of which is connected to thepositioning column 521 protruded from thelinkage rod 52. Since thetension spring 15 is elastic, tension between thelinkage rod 52 and the underframe structure can be strengthened. In addition, the structure is easy to restore to the original position, and thus highly practicable. - As a preferred implementation, the
seat mounting rack 14 is a bent sheet metal part with a "┐"-shaped cross section. Theseat mounting rack 14 is set as a structure of a bent sheet metal part, so that a plane thereof for bearing the major sofa structure is increased, that is, a plane of theseat mounting rack 14 facing upward is increased. In the prior art, structurally, theseat mounting racks 14 are almost single sheet metal parts or have a narrow plane facing upward. Thus, the sofa chair frame can provide better balance when bearing the major sofa structure, and can facilitate mounting of the major sofa structure. In this way, the practicability of the sofa chair frame is further enhanced. - The activating device includes an activating
stretching rod 41, two ends of which are connected to thefront beam 11 and theback beam 12 by the fixinglug 411; and the activatingmotor 42 which is mounted on the activatingstretchable rod 41 and in an activation connection with the activatingstretchable rod 41. The activating device is located above the underframe structure and provides activating force by the activatingmotor 42. The stretch amount of the activatingstretchable rod 41 is adjusted according to the unfolding extent of the leg structure and the back structure. In this way, the whole leg structure and the back structure are effectively driven. - Pivot members are provided at all pivot positions of the components, for realizing connections between the components, and will not be enumerated. This is well known to those skilled in the art.
- The foregoing descriptions are merely preferred embodiments of the sofa chair frame.
