DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 5 The utility model provides a technical solution: a flip sofa assembly, including a first cushion 1, a front outer wall of the first cushion 1 is provided with a plurality of rotating blocks a2, a rotating shaft 3 is horizontally penetrated through the inner walls of the plurality of rotating blocks a2, a rotating assembly 4 is sleeved on both left and right ends of the rotating shaft 3, one side of the outer wall of the rotating assembly 4 is threadedly connected to the outer wall of one side of the second cushion 5, a sliding bar 6 is welded to the bottom of the second cushion 5, a base 7 is provided at the bottom of the sliding bar 6, and a sliding sleeve 8 is provided on the base 7 directly below the first cushion 1, and a plurality of rotating blocks b9 are provided on the front outer wall of the second cushion 5.
[0022] In this embodiment, Figure 1 and Figure 4As shown, the rotating assembly 4 is composed of a rotating plate a401, a rotating plate b402 and a fastening screw 403, wherein the rotating plate a401 is screwed to the left and right outer walls of the first cushion 1 by the fastening screws 403, and the rotating plate b402 is screwed to the left and right outer walls of the second cushion 5 by the fastening screws 403, and the rotating shaft 3 is horizontally penetrated at the overlapping part of the rotating plate a401 and the rotating plate b402; it should be noted that when the user needs to flip the sofa assembly, he only needs to manually rotate and flip the first cushion 1, The angle between it and the second cushion 5 is changed. At the same time, the rotating plate a401 will rotate around the rotating shaft 3 that passes through the overlapping part of it and the rotating plate b402, and the connecting rotating block a2 arranged on the front outer wall of the first cushion 1 will also rotate around the rotating shaft 3. During this period, the second cushion 5 can be manually pulled to slide in the direction of the first cushion 1 to change its original position, so that the angle between the first cushion 1 and the second cushion 5 is changed from the original 180° angle to 90°, and the sofa bed is transformed from a flat sofa bed to a sofa cushion that can be leaned on.
[0023] In this embodiment, Figure 2 and Figure 3 As shown, the slide bar 6 and the slide sleeve 8 form a sliding connection; it should be noted that when the user needs to transform the flat first cushion 1 and the second cushion 5 from a sofa bed into cushions that can be leaned on, it is only necessary to manually rotate the first cushion 1 around the rotating shaft 3 through the rotating component 4 while pushing the second cushion 5 to slide in the direction of the first cushion 1 to change its original position. During this process, the slide bar 6 arranged at the bottom of the second cushion 5 will slide into the interior of the slide sleeve 8 under the push of the user, so that the angle between the first cushion 1 and the second cushion 5 is changed from 180° to 90°, and the entire sofa assembly can be easily flipped.
[0024] In this embodiment, Figure 3 and Figure 5 As shown, an elastic clip 601 is provided on the outer wall of one side of the slide bar 6, and limiting holes 801 are provided on the left and right ends of the outer wall on the same side of the slide sleeve 8; it should be noted that when the user manually pushes the second cushion 5 to slide in the direction of the first cushion 1, the slide bar 6 arranged at the bottom of the second cushion 5 will directly slide into the interior of the slide sleeve 8, and at the same time, the elastic clip 601 arranged on the outer wall on one side of the slide bar 6 is always restricted during the sliding process, and slides along the inner wall of the slide sleeve 8 until the elastic clip 601 slides through the limiting hole 801 opened on the outer wall on the same side of the slide sleeve 8, and pops out therefrom to complete the position limitation of the entire second cushion 5.
[0025] In this embodiment, Figure 2 and Figure 3As shown, the base 7 is composed of a sleeve 701 and a slide 702, wherein the sleeve 701 is arranged directly below the first cushion 1, and the slide 702 is slidably connected with the sleeve 701 and is arranged directly below the second cushion 5; it should be noted that when the user needs to flip the entire sofa assembly, the second cushion 5 can be pushed to slide in the direction of the first cushion 1 while manually adjusting the position of the first cushion 1 to change the angle between the two, and while the second cushion 5 slides into the interior of the sleeve 8 through the slide bar 6 provided at the bottom thereof, the user can manually push the slide 702 to slide into the interior of the sleeve 701 again, thereby changing the length of the entire base 7 from the length of the bed to the length of the normal sofa base 7.
[0026] In this embodiment, Figure 4 As shown, the connecting block a2 and the connecting block b9 are both rotatably connected with the rotating shaft 3, and the outer walls of the two are covered with velvet cloth; it should be noted that when the user manually rotates the first cushion 1 and pushes the position of the second cushion 5, the connecting block a2 and the connecting block b9 will also simultaneously change the angle between the connecting block a2 and the connecting block b9 around the rotating shaft 3 passing through the inside of the two, which is more convenient and flexible during use, and because the outer walls of the connecting block a2 and the connecting block b9 are covered with velvet cloth, the user will not feel discomfort even if his body touches the outer walls of the two.
[0027] The use method and advantages of the utility model: When the reversible sofa assembly is in use, the working process is as follows:
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the user needs to flip the sofa assembly, he only needs to manually turn the first cushion 1 to change the angle between it and the second cushion 5. At the same time, the rotating plate a401 will rotate around the rotating shaft 3 that passes through the overlapping part of the rotating plate a401 and the rotating block a2 arranged at the front outer wall of the first cushion 1 will also rotate around the rotating shaft 3. During this period, the second cushion 5 can be pushed to slide in the direction of the first cushion 1 to change its original position, so that the bottom of the second cushion 5 is The slide bar 6 will slide into the interior of the slide sleeve 8 under the push of the user. At the same time, the elastic clip 601 arranged on the outer wall of one side of the slide bar 6 will slide along the inner wall of the slide sleeve 8 until the elastic clip 601 slides through the limiting hole 801 opened on the outer wall of the same side of the slide sleeve 8 and pops out from it to complete the position limitation of the entire second cushion 5. Then the user can manually push the slide seat 702 to slide into the interior of the sleeve seat 701 again, thereby changing the length of the entire base 7 from the length of the bed to the length of the normal sofa base 7.
[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
