One end of the gear angle adjuster is connected to the bottom end of the backrest board, and the other end of the gear angle adjuster is connected to the side of the top end of the sofa iron frame. And the gear angle adjuster is a multi-gear angle adjuster. Vertically arranged movable connection seats are provided on both sides of the top end inside the backrest board, and a backrest footrest is movably arranged at the bottom end of the movable connection seat. And the backrest footrest is movable inside the backrest board through the movable connection seat, and then is movably stored inside the backrest board in the same vertical plane as the backrest board.

[0005] Preferably, the backrest board is provided with nylon straps, and the nylon straps are wound around the outside of the backrest board, and the nylon straps are in the same vertical plane as the backrest board.

[0006] Preferably, a plurality of springs are arranged on the top end of the sofa iron frame horizontally, and the plurality of springs are arranged at equal intervals, and the plurality of springs are in the same horizontal plane as the top end of the sofa iron frame.

[0007] Preferably, support footrests are vertically arranged at the four corners of the bottom surface of the sofa iron frame, and a connection block is arranged between the support footrest and the sofa iron frame, and the support footrest is vertically arranged at the bottom end of the connection block.

[0008] Preferably, both the outside of the sofa iron frame and the backrest board are wrapped with a sofa fabric cover, and the sofa fabric cover is a zippered fabric cover.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: By means of the gear angle adjuster, the backrest plate can be actively folded and bent on one side of the sofa iron frame, and the connection angle between the backrest plate and the sofa iron frame can be adjusted, so as to adapt to the backrest angles required by different people. The backrest plate can be folded and pressed on the sofa iron frame, and then it can move inside the backrest plate through the movable connection seat, and then be actively stored inside the backrest plate in the same vertical plane as the backrest plate. When the connection angle between the backrest plate and the sofa iron frame is bent to 180 degrees through the gear angle adjuster and the backrest plate and the sofa iron frame are in the same horizontal plane, the backrest footrest folds out from inside the backrest plate, so that the connection between the backrest footrest and the movable connection seat forms a 90-degree angle, and then the backrest footrest supports the backrest plate, so that the backrest plate and the sofa iron frame are folded and switched from the sofa main body form to the sofa bed form.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0017] Please refer to Figures 1-3 In the embodiment of the present utility model, a folding sofa bed includes a sofa iron frame 1. On one side of the sofa iron frame 1, a backrest plate 2 is movably arranged, and a gear angle adjuster 6 is arranged between the backrest plate 2 and the sofa iron frame 1. One end of the gear angle adjuster 6 is connected to the bottom end of the backrest plate 2, and the other end of the gear angle adjuster 6 is connected to the side edge of the top end of the sofa iron frame 1. And the gear angle adjuster 6 is a multi-gear angle adjuster. Thus, through the gear angle adjuster 6, the backrest plate 2 can be movably folded on one side of the sofa iron frame 1 and the connection angle between the backrest plate 2 and the sofa iron frame 1 can be adjusted, so as to adapt to the backrest angles required by different people and the backrest plate 2 can be folded and pressed on the sofa iron frame 1. On both sides of the top end inside the backrest plate 2, movable connection seats 8 are vertically arranged. At the bottom end of the movable connection seats 8, backrest footrests 3 are movably arranged. And the backrest footrests 3 can move inside the backrest plate 2 through the movable connection seats 8. Then, they can be movably stored inside the backrest plate 2 in the same vertical plane as the backrest plate 2. And when the connection angle between the backrest plate 2 and the sofa iron frame 1 is folded into 180 degrees through the gear angle adjuster 6 and the backrest plate 2 and the sofa iron frame 1 are in the same horizontal plane, the backrest footrests 3 are folded out from inside the backrest plate 2, so that the connection between the backrest footrests 3 and the movable connection seats 8 forms a 90-degree angle. Thus, the backrest plate 2 is supported by the backrest footrests 3, so that the connection between the backrest plate 2 and the sofa iron frame 1 can be folded and switched from the sofa main body form to the sofa bed form.

[0018] The backrest plate 2 is provided with nylon straps 4, and the nylon straps 4 are wound around the outside of the backrest plate 2, and the nylon straps 4 and the backrest plate 2 are in the same vertical plane. Thus, through the nylon straps 4, the supporting ability of the surface of the backrest plate 2 can be increased and the supporting area of the backrest plate 2 can be expanded.

[0019] A plurality of springs 5 are arranged on the sofa iron frame 1, and the plurality of springs 5 are all horizontally located at the top end of the sofa iron frame 1. The plurality of springs 5 are equally spaced between them, and the plurality of springs 5 are all in the same horizontal plane as the top end of the sofa iron frame 1. Thus, through the plurality of springs 5, when a user sits on the sofa iron frame 1, the user's buttocks can be buffered and supported.

[0020] Supporting footrests 7 are vertically arranged at the four corners of the bottom surface of the sofa iron frame 1, and a connecting block 9 is arranged between the supporting footrests 7 and the sofa iron frame 1. And the supporting footrests 7 are vertically arranged at the bottom end of the connecting block 9, and multiple sofa iron frames 1 can be assembled and connected through the connecting block 9.

[0021] Both the outside of the sofa iron frame 1 and the backrest plate 2 are wrapped with a sofa fabric cover (not shown in the figure), and the sofa fabric cover is a zippered fabric cover, so that it can be quickly disassembled from the sofa iron frame 1 and the backrest plate 2 or assembled onto the sofa iron frame 1 and the backrest plate 2.

[0022] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
