[0026] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-3 As shown, a built-in frame of a sofa includes a support body 1 and a plurality of frame support plates 2 installed on the support body 1, wherein the frame support plates 2 are provided with a plurality of fixing holes 3 and straight slot holes 4.

[0028] Furthermore, the frame support plate 2 is a bearing component composed of a supporting surface 21 provided with a plurality of fixing holes 3 and a mounting surface 22 provided with straight slot holes 4 which are perpendicular to each other.

[0029] Furthermore, the supporting surfaces 21 of the plurality of frame support plates 2 are all located on the same horizontal plane. The supporting surface 21 is a component of the frame support plate 2 used to support the built-in frame of the sofa. In some embodiments, both sides of the supporting surface 21 can be used to support the built-in frame of the sofa, specifically to change the vertical installation direction of the frame support plate 2.

[0030] Furthermore, the number of the straight slot holes 4 provided on the frame support plate 2 is at least two; the straight slot holes 4 are threaded with fasteners 5 for mounting the frame support plate 2 to the bracket body 1 , and the fasteners 5 are detachable fasteners 5 .

[0031] In this embodiment, the frame pallet 2 and the bracket body 1 are installed by fasteners 5, and the straight slot holes 4 provided on the mounting surface 22 of the frame pallet 2 allow the frame pallet 2 to become a component with adjustable height. The frame pallet 2 is loosened by loosening the fasteners 5 that were originally in a tightened state, and the position of the frame pallet 2 can be adjusted by moving the frame pallet 2 up and down and adjusting the position of the straight slot holes 4. When the desired height is adjusted, the fasteners 5 are tightened to fasten the frame pallet 2 to the bracket body 1, thereby achieving the purpose of adjusting the height of the frame pallet 2.

[0032] Furthermore, the support body 1 includes a telescopic mechanism 6, a backrest mechanism 7 and a symmetrically arranged main beam 8, wherein the telescopic mechanism 6 is connected to one end of the main beam 8, and the backrest mechanism 7 is connected to the other end of the main beam 8. The telescopic mechanism 6 is a movable part on the support body 1, which is used to telescope and extend the leg support of the sofa; the backrest mechanism 7 is used to install and connect the backrest of the sofa, and connect and fix the backrest of the sofa to the sofa body; the support body 1 as a whole serves as the internal skeleton of the bottom of the sofa, and the main beam 8 is set to carry the bottom frame of the sofa.

[0033] Furthermore, the inner side surface of the main beam 8 is provided with a plurality of mounting holes 9 corresponding to the positions of the straight slot holes 4 and used to cooperate with the fasteners 5 to install the frame support plate 2. The frame support plate 2 is detachably mounted on the inner side surface of the main beam 8 via the fasteners 5.

[0034] Furthermore, the telescopic mechanism 6 includes symmetrically arranged telescopic frames 10 , a first connecting beam 11 and a telescopic cylinder 12 . The telescopic frames 10 are movably installed at the lower part of the main beam 8 , and the first connecting beam 11 is connected between the symmetrically arranged telescopic frames 10 .

[0035] Furthermore, the backrest mechanism 7 includes a symmetrically arranged backrest frame 13 and a second connecting beam 14 . The backrest frame 13 is fixedly mounted on one end of the main beam 8 by bolts, and the second connecting beam 14 is connected between the symmetrically arranged backrest frames 13 .

[0036] Furthermore, the telescopic cylinder 12 is installed between the first connecting beam 11 and the second connecting beam 14, and its setting direction is parallel to the main beam 8. The driving part of the telescopic cylinder 12 is hinged to the second connecting beam 14, and its telescopic end is hinged to the first connecting beam 11. By setting the telescopic cylinder 12 to drive the first connecting beam 11, the telescopic frame 10 connected to the first connecting beam 11 can be driven to extend, so that the sofa leg support part can be flipped from the original vertical state to the horizontal state.

[0037] Furthermore, the telescopic frame 10 is movably connected to the main beam 8 through a first connecting rod 15 and a second connecting rod 16, and a leg support connecting plate 17 for installing the leg support of the sofa is provided at one end of the telescopic frame 10, and one end of the first connecting rod 15 is movably set on the outer wall of the main beam 8 near the middle position, and one end of the second connecting rod 16 is movably set on the outer wall of the main beam 8 near one end of the backrest mechanism 7.

[0038] The working process and principle of the utility model are as follows:

[0039] Under normal conditions, the frame support plate 2 is connected and fastened to the main beam 8 by fasteners 5. The mounting holes 9 on the main beam 8 correspond to the straight slot holes 4 on the frame support plate 2. The fasteners 5 penetrate the straight slot holes 4 and the mounting holes 9 to install the frame support plate 2 on the main beam 8. When the fasteners 5 are in a loose state, due to the restriction of the mutual cooperation between the straight slot holes 4 and the fasteners 5, the frame support plate 2 can move in the vertical direction, thereby achieving the purpose of adjusting the height, so that the height of the built-in frame at the bottom of the sofa can be adjusted, thereby adjusting the sinking height of the sofa cushion part, which improves the flexibility and enables the sinking height of the sofa cushion part to be adjusted within a certain range, thereby achieving the adjustment of the installation height of the bottom frame of the sofa and facilitating the replacement and repair of the frame support plate 2 when it is damaged.

[0040] The above detailed description of the specific implementation of the utility model is only used as an example. The utility model is not limited to the specific implementation described above. The technicians in the industry should understand that the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
