Sofa frames are a kind of household item, and the quality of the sofa frame directly affects the quality of the sofa.

[0003] The Chinese patent publication (CN201620172258.4) discloses a folding sofa bed frame and a folding sofa bed, wherein the first rotating frame and the second rotating frame are turned upward under the connection of the connecting bracket to make the surface cushion fixing bracket translate in an arc direction to above the bottom cushion fixing bracket, so that the surface cushion fixed on the surface cushion fixing bracket is stacked above the bottom cushion fixed on the bottom cushion fixing bracket, and the first rotating frame and the second rotating frame are turned downward under the connection of the connecting bracket to make the surface cushion fixing bracket translate in an arc direction to be at the same level as the bottom cushion fixing bracket. However, when this type of sofa frame is in use, the fixed bracket is supported only by the rotating frame, which is easily damaged due to excessive force on the rotating frame, affecting the service life. The application lacks a supporting structure for the fixed bracket in different scenarios, and the supporting strength of the fixed bracket is insufficient;

[0004] In order to solve the above technical problems, a foldable and storable sofa frame is proposed. Utility Model Content

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, the embodiment of the utility model provides a foldable and storable sofa frame, which is composed of a main body mechanism 10 and a supporting mechanism 20.

[0029] The main body mechanism 10 includes a base frame 11, a first fixed frame 18 and a second fixed frame 33. Four supporting legs 12 are fixedly connected to the bottom of the base frame 11. Two supporting members 37 are fixedly connected to both sides of the base frame 11. The first connecting frame 13 and the second connecting frame 14 are rotatably installed on one side of the two supporting members 37. The second connecting plate 36 is symmetrically fixedly connected to one side of the first fixed frame 18. One side of the second connecting plate 36 is hinged to the first connecting frame 13 and the second connecting frame 14. One side of the second fixed frame 33 is symmetrically fixedly connected to the first connecting plate 17. One side of the first connecting plate 17 is hinged to the first connecting frame 13 and the second connecting frame 14. The first connecting frame 13 cooperates with the second connecting frame 14 to enable the first fixed frame 18 to move when the second fixed frame 33 moves, so as to facilitate the overall folding and storage. In order to make the unfolding more convenient, a spring 15 is fixedly connected to one side of the first connecting frame 13. One end of the spring 15 is fixedly connected to the second connecting frame 14. The spring 15 offsets the influence of gravity when the second fixed frame 33 is unfolded.

[0030] In one embodiment, four limit blocks 16 are fixedly connected to one side of the base frame 11, and four slots 34 are opened on one side of the second fixing frame 33. The sizes of the limit blocks 16 and the slots 34 match each other, thereby enhancing the stability of the base frame 11 when in contact with the second fixing frame 33.

[0031] In one embodiment, in order to facilitate the installation and fixation of the sofa cushion, fixing members 19 are symmetrically installed on one side of the first fixing frame 18 and the second fixing frame 33 at equal distances.

[0032] In one embodiment, in order to enhance the structural strength of the base frame 11, the first fixing frame 18 and the second fixing frame 33, a first reinforcing rod 31 is symmetrically fixedly connected to one side of the first fixing frame 18, two second reinforcing rods 32 are fixedly connected to both sides of the base frame 11, and a third reinforcing rod 35 is symmetrically fixedly connected to one side of the second fixing frame 33.

[0033] The supporting mechanism 20 includes a mounting seat 21 and a supporting rod 22. The supporting rod 22 is fixedly connected to one side of the base frame 11. The first connecting frame 13 is supported by the supporting rod 22 to make the first connecting frame 13 more stable. The two mounting seats 21 are symmetrically fixedly connected to one side of the second fixing frame 33. A sleeve 23 is rotatably installed on one side of the mounting seat 21. A fixing rod 26 is slidably installed inside the sleeve 23. One end of the fixing rod 26 is fixedly connected to a supporting block 24. Screw holes 27 are equidistantly distributed inside the fixing rod 26. A bolt 25 is threadedly connected to one side of the sleeve 23. One end of the bolt 25 is threadedly connected to the fixing rod 26 through the screw hole 27. The use length of the fixing rod 26 is adjusted by the bolt 25 cooperating with the screw hole 27 to meet the support requirements of the second fixing frame 33 in different scenarios.

[0034] In one embodiment, in order to prevent the sleeve 23 from affecting the installation of the sofa cushion, a limiting plate 28 is fixedly connected to one side of the mounting seat 21 .

[0035] When the utility model is in operation: the sofa cushion is mounted on the first fixing frame 18 and the second fixing frame 33 through the fixing member 19. When it needs to be unfolded for use, the second fixing frame 33 is pulled to drive the second fixing frame 33 to move from the top of the base frame 11 to the side of the base frame 11. During the movement, the first connecting frame 13 and the second connecting frame 14 drive the first fixing frame 18 to move out of the base frame 11, so that the first fixing frame 18 is flush with the second fixing frame 33. At this time, the first connecting frame 13 contacts the support rod 22 to support the second fixing frame 33, rotate the sleeve 23, and draw the fixing rod 26 out of the sleeve 23 to make the support block 24 contact the ground, and fix the fixing rod 26 through the bolt 25, so that the fixing rod 26 cooperates with the sleeve 23 to support one side of the second fixing frame 33, thereby enhancing the stability of the second fixing frame 33 and sharing the force of the first connecting frame 13 and the second connecting frame 14. When folding, the second fixing frame 33 is reset to drive the first fixing frame 18 to retract into the base frame 11.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
