The axial end of the first connecting rod 5 provided with the waist hole 51 is provided with an arc-shaped limiting surface I which is matched and connected with the limiting screw. The first arc-shaped limiting surface specifically comprises a right-angle portion 53 for limiting the limiting screw when the first cushion frame 2 and the second cushion frame 3 are located on the same horizontal plane, an arc-shaped portion 54 for limiting the limiting screw when the second cushion frame 3 and the first connecting rod 5 are folded, and a protruding portion 55 for limiting the limiting screw after the second cushion frame 3 and the first connecting rod 5 are folded.

When the sofa bed is used as a bed, when the first cushion frame 2 and the second cushion frame 3 are positioned on the same horizontal plane, the screw rod of the limit screw is in abutting connection with the right-angle part 53, the guide screw is positioned in the U-shaped clamping groove part 46, and the screw rod of the connecting screw III is in abutting connection with the first clamping part 56, so that the first cushion frame 2 or the second cushion frame 3 cannot cause the corresponding second cushion frame 3 or the first cushion frame 2 to generate tilting phenomenon when receiving downward gravity, the structural stability of the sofa bed is improved, and the use experience of a user is further improved.
The specific use process of the second connecting piece is as follows, when the sofa bed needs to be used as a sofa, the first connecting rod 5 and the second connecting rod 6 need to be rotated upwards along the first cushion frame 2, in the rotating process, the first connecting rod 5 rotates around the second connecting screw, the second connecting rod 6 rotates around the third connecting screw, and the screw rod of the third connecting screw enters the second clamping part 58 after being guided from the first clamping part 56 through the arc-shaped part 57, so that the rotating angle of the first connecting rod 5 and the second connecting rod 6 is limited. At this time, the shaft of the stopper screw is separated from the right-angle portion 53, and the guide screw is separated from the U-shaped catching groove portion 46. Then, the second cushion frame 3 is rotated along the first link 5 and the second link 6, and during the rotation process, the screw rod of the limit screw moves along the arc portion 54 to abut against the protruding portion 55, and the screw rod of the guide screw moves along the arc guide portion 47 to abut against the protruding portion 48, so as to limit the rotation angle of the second cushion frame 3.
When the sofa bed needs to be used as a bed, the second cushion frame 3 needs to be rotated in the opposite direction of the first connecting rod 5 and the second connecting rod 6 until the screw rod of the guide screw abuts against the outlet edge of the U-shaped clamping groove part 46, so that the rotation angle of the second cushion frame 3 is limited. Then the first connecting rod 5 and the second connecting rod 6 are reversely rotated along the first cushion frame 2, in the rotating process, the first connecting rod 5 rotates around the second connecting screw, the second connecting rod 6 rotates around the third connecting screw, and the screw rod of the third connecting screw is guided from the second clamping part 58 through the arc-shaped part 57 and then enters the first clamping part 56, so that the rotating angle of the first connecting rod 5 and the second connecting rod 6 is limited. At this time, the screw shaft of the limit screw is again abutted against the right-angle portion 53, and the guide screw is again entered into the U-shaped catching groove portion 46.
The connecting frame 4 further comprises a reinforcing plate for connecting the bottom plate 41 and the top plate 42, and the supporting strength of the whole connecting frame 4 can be improved through the reinforcing plate, so that the structural stability of the second connecting piece is further improved. The sofa bed frame comprises two second connecting pieces, so that two first connecting rods 5 are arranged, two supporting rods 7 are arranged between the two first connecting rods 5, and the supporting strength of the second connecting pieces can be improved in an auxiliary mode, so that the supporting strength of the whole sofa bed frame is improved.
The second cushion frame 3 comprises a front stay bar, a side stay bar, a rear stay bar, a first support net frame and a folding support leg. The axial end of the side stay is connected with the axial end of the front stay, the axial other end is connected with the side plate 43, the axial end of the rear stay is connected with the bottom plate 41, i.e. the right-angle butt joint of the rear stay and the side stay is used for installing the connecting frame 4. The first support net frame is paved at the tops of the front stay bar, the side stay bar and the rear stay bar, and the folding support legs are arranged at the bottoms of the joints of the front stay bar and the side stay bar. The second cushion frame 3 is externally covered with a foam cushion and an outer sleeve.
The first cushion frame 2 comprises a first frame-shaped supporting frame, a second supporting frame and a supporting leg installing plate. The short side of the first frame-shaped support frame is connected with the second connecting screw and the third connecting screw, the second supporting net rack is paved at the top of the first frame-shaped support frame, and the support leg mounting plate is arranged at the bottom of the right angle of the first frame-shaped support frame and used for mounting support legs. The first cushion frame 2 is externally covered with a foam cushion and an outer sleeve.
The backrest frame 1 comprises a frame-shaped support frame II, a support net rack III paved at the top of the frame-shaped support frame II, and a folding support leg II arranged at the bottom of the frame-shaped support frame II. The outer part of the backrest frame 1 is covered with a foam cushion and an outer sleeve.
In addition, the first connecting piece adopts the first connecting piece with the adjustable backrest in the prior art. A reinforcing column is arranged between the two first connecting pieces, so that the supporting strength of the whole sofa bed frame is further improved.
The sofa bed is particularly used in the following way, when the sofa bed needs to be unfolded to be used as a bed, the second cushion frame 3 is only required to be rotated for approximately 90 degrees along the second connecting piece, then the second cushion frame 3 and the second connecting piece are rotated for approximately 90 degrees along the first cushion frame 2, and then the folding support feet hidden inside the outer sleeve of the second cushion frame 3 are rotated to be unfolded to be in contact with the ground. The backrest frame 1 is then rotated by the first connecting means to lie in the same horizontal plane as the first cushion frame 2, and finally the folding leg hidden inside the outer casing of the backrest frame 1 is rotated open to contact the ground. The sofa bed is very convenient to unfold and operate.
When the sofa bed is required to be folded and folded to be used as a sofa, the backrest frame 1 is only required to be rotated to a required backrest angle through the first connecting piece, and then the folding support legs of the backrest frame 1 are rotated and folded and hidden inside the outer sleeve of the backrest frame 1. The second cushion frame 3 is then rotated with the second connector through an angle of approximately 90 degrees along the first cushion frame 2, and then the second cushion frame 3 is rotated with an angle of approximately 90 degrees along the second connector, so that the foam-rubber cushion on the second cushion frame 3 is overlapped with the foam-rubber cushion on the first cushion frame 2, and finally the folding support leg of the second cushion frame 3 is rotated, folded and hidden inside the outer sleeve of the second cushion frame 3. The folding operation of the sofa bed is also very simple.
The above examples are only illustrative of the preferred embodiments of the present invention and do not limit the spirit and scope of the present invention. Various modifications and improvements of the technical scheme of the present invention will fall within the protection scope of the present invention without departing from the design concept of the present invention, and the technical content of the present invention is fully described in the claims.
