[0016] Referring to an embodiment herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0017] An auxiliary device for assembling steel materials of a sofa bed frame, as Figures 1 - 3As shown in the figure, it includes a moving plate 1, guide rails 2, support frames 3, sliding frames 4, pulleys 5, first sliders 6, limiting frames 7, first screws 8, clamping blocks 9, second sliders 10, second screws 11 and a placing plate 12. Guide rails 2 are connected to the upper sides of the front and rear parts of the moving plate 1. Two left and right support frames 3 are slidably connected to the middle parts of the guide rails 2. Two sliding frames 4 are slidably connected between the left and right parts of the guide rails 2. Two front and rear pulleys 5 are rotatably connected to the lower parts of the sliding frames 4. Two front and rear pulleys 5 are also rotatably connected to the left and right parts of the moving plate 1. The upper pulleys 5 are all in contact with the moving plate 1. Two first sliders 6 are slidably connected to the front and rear parts of the sliding frames 4. Limiting frames 7 are connected to the first sliders 6. First screws 8 are threadedly connected to the limiting frames 7. Clamping blocks 9 are rotatably connected to the outer sides of the first screws 8. Two second sliders 10 are connected to the front and rear sides of the clamping blocks 9. The second sliders 10 are all slidably connected to the adjacent limiting frames 7. Second screws 11 are threadedly connected to the middle parts of the first sliders 6. Grips are provided on the upper sides of the second screws 11 for easy gripping and rotation. Placing plates 12 are rotatably connected to the lower sides of the second screws 11.

[0018] When using this device, first move the moving plate 1 to the assembly area of the sofa bed frame steel through the lower pulleys 5. Then move the first slider 6 back and forth according to the size of the side frame to adjust the position of the limiting frame 7. Then pass the side frame through the limiting frame 7 so that the side frame contacts the placing plate 12. Then rotate the first screw 8 so that the first screw 8 moves under the action of the thread, driving the second slider 10 to move on the limiting frame 7, making the clamping block 9 move to clamp and fix the side frame. Then place the cross beam on the support frame 3 and then install and fix the cross beam on the side frame. When different-sized cross beams need to be installed, the sliding frame 4 can be moved and adjusted on the guide rail 2 according to the length of the cross beam, making the pulley 5 rotate, and then install the cross beam. When the position where the cross beam needs to be installed on the side frame is different, the grip can be rotated to drive the second screw 11 to rotate, so that the second screw 11 moves under the action of the thread, driving the placing plate 12 to move up and down, and then making the side frame move up and down. Then install the cross beam on the side frame, which can facilitate the assembly of different-sized steels, be convenient to adapt to different assembly requirements, save manpower, and improve the convenience of using this device.
