[0057] In the present application, since the two armrest supporting portions 1 on the two sides, the backrest portion 2, and the front baffle portion 3 make a circle to form the accommodating cavity, the terms “inner side” and “outer side” referred to herein are based on that a side close to the accommodating cavity is referred to as an inner side, and a side away from the accommodating cavity is referred to as an outer side herein. Since the base 5 can rotate, the sofa chair can rotate when the base 5 rotates, and the user can rotate at any angle when sitting on the sofa chair accordingly, thereby meeting use requirements of the user and improving user experience.

[0058] The seat cushion 6 is mounted in the opening in the top of the accommodating cavity, and the seat cushion 6 is supported by the connecting frame 4 and the front baffle portion 3, so that when the user sits on the seat cushion 6, the seat cushion 6 supports hips of the user, the two armrest supporting portions 1 on the two sides support the hands of the user, and the backrest portion 2 supports a back of the user, thereby meeting the requirements of the user for sitting on the sofa chair.

[0059] Since in the present application, two side ends of the backrest portion 2 are detachably connected with the rear ends of the two armrest supporting portions 1 on the two sides respectively, the backrest portion 2 may be assembled on or disassembled from the two armrest supporting portions 1 on the two sides; since two side ends of the front baffle portion 3 are detachably connected with the front ends of the two armrest supporting portions 1 on the two sides respectively, the front baffle portion 3 may be assembled on or disassembled from the two armrest supporting portions 1 on the two sides; and since two ends of the connecting frame 4 are detachably connected with the two armrest supporting portions 1 on the two sides respectively, the two armrest supporting portions 1 on the two sides may be assembled or disassembled.

[0060] Therefore, during transportation of the sofa chair, the two armrest supporting portions 1, the backrest portion 2, the front baffle portion 3, the connecting frame 4, the base 5, and the seat cushion 6 can be respectively packaged and transported by disassembling the backrest portion 2, the front baffle portion 3, and the two armrest supporting portions 1 on the two sides, thereby greatly reducing packaging volumes needed during transportation, facilitating the transportation of the sofa chair, and reducing transportation costs of the sofa chair.

[0061] In the present application, the two armrest supporting portions 1 on the two sides are further connected through the connecting frame 4 when the two armrest supporting portions 1 on the two sides, the backrest portion 2, and the front baffle portion 3 make a circle to form the frame of the sofa chair by splicing the backrest portion 2 with the rear ends of the two armrest supporting portions 1 on the two sides and splicing the front baffle portion 3 with the front ends of the two armrest supporting portions 1 on the two sides, thereby realizing better structural integrity and high structural stability of the sofa chair, and then improving user experience.

[0062] In the present application, the seat cushion 6 is mounted in the opening in the top of the accommodating cavity, a middle rear portion of the seat cushion 6 can be supported by the connecting frame 4 located in the accommodating cavity, and meanwhile, a front of the seat cushion 6 is supported by the front baffle portion 3, so as to further improve the supporting strength of the seat cushion 6, thereby further improving the structural stability of the sofa chair and improving the user experience.

[0063] In this embodiment, the swivel sofa chair further includes a panel decorative jacket 7 and a baffle decorative jacket 8. After the backrest portion 2 is spliced with the rear ends of the two armrest supporting portions 1 on the two sides, the panel decorative jacket 7 is arranged on outer sides of the spliced armrest supporting portions 1 on the two sides and backrest portion 2 in a sleeving manner, so that the spliced armrest supporting portions 1 on the two sides and backrest portion 2 form an integrated structure in an appearance; on one hand, more comfortable user experience is brought when the backrest portion 2 supports the back of the user, and the two armrest supporting portions 1 on the two sides support the hands of the user; and on the other hand, an appearance of the finished sofa chair can be more attractive.

[0064] After the front baffle portion 3 is spliced with the front ends of the two armrest supporting portions 1 on the two sides, and the seat cushion 6 is mounted in the opening in the top of the accommodating cavity, the baffle decorative jacket 8 is arranged on outer sides of the mounted seat cushion 6 and front baffle portion 3 in a sleeving manner, so that the mounted seat cushion 6 and front baffle portion 3 form an integrated structure in the appearance; on one hand, more comfortable user experience is brought when the seat cushion 6 supports the hips of the user; and on the other hand, the appearance of the finished sofa chair can be more attractive, thereby improving the product competitiveness of the sofa chair.

[0065] Since the panel decorative jacket 7 and the baffle decorative jacket 8 directly make contact with the user during actual use of the sofa chair, the panel decorative jacket 7 and the baffle decorative jacket 8 should be made of skin-friendly fabric. In the present application, the panel decorative jacket 7 and the baffle decorative jacket 8 are preferably made of lamb wool fabric, so as to bring more comfortable user experience.

[0066] In this embodiment, the two armrest supporting portions 1, the backrest portion 2, the front baffle portion 3, and the seat cushion 6 include wood boards 11 on respective inner sides, and lint jackets 12 wrapping the wood boards 11, and hook-and-loop fasteners are arranged on inner sides of the panel decorative jacket 7 and the baffle decorative jacket 8. When the panel decorative jacket 7 is arranged on outer sides of the spliced armrest supporting portions 1 on the two sides and backrest portion 2 in a sleeving manner, the hook-and-loop fastener on the inner side of the panel decorative jacket 7 may adhere to the lint jackets 12 on the outer sides of the two armrest supporting portions 1 and the backrest portion 2, so as to fix the panel decorative jacket 7 to the outer sides of the two armrest supporting portions 1 on the two sides and the backrest portion 2.

[0067] When the baffle decorative jacket 8 is arranged on outer sides of the mounted seat cushion 6 and front baffle portion 3, the hook-and-loop fastener on the inner side of the baffle decorative jacket 8 may adhere to the lint jackets 12 on the outer sides of the seat cushion 6 and the front baffle portion 3, so as to fix the baffle decorative jacket 8 to the outer sides of the seat cushion 6 and the front baffle portion 3, thereby improving the structural stability of the sofa chair and improving the user experience.

[0068] On the contrary, when the sofa chair is disassembled, firstly, the hook-and-loop fastener on the inner side of the baffle decorative jacket 8 may be separated from the lint jackets 12 on the outer sides of the seat cushion 6 and the front baffle portion 3, the baffle decorative jacket 8 arranged on the outer sides of the seat cushion 6 and the front baffle portion 3 in a sleeving manner is taken down, then the seat cushion 6 is taken out of the opening in the top of the cavity, and the front baffle portion 3 is separated from the two armrest supporting portions 1 on the two sides. The hook-and-loop fastener on the inner side of the panel decorative jacket 7 is separated from the lint jackets 12 on the outer sides of the two armrest supporting portions 1 and the backrest portion 2, so that the panel decorative jacket 7 arranged on the outer sides of the two armrest supporting portions 1 on the two sides and the backrest portion 2 in a sleeving manner can be taken down.

[0069] Specifically, the lint jackets 12, wrapping the outer sides of the wood boards 11, of the two armrest supporting portions 1, the backrest portion 2, the front baffle portion 3, and the seat cushion 6 may be fixed to the wood boards 11 through gun nails after being arranged on the outer sides of the wood boards 11 in a sleeving manner, thereby realizing higher structural integrity of the two armrest supporting portions 1, the backrest portion 2, the front baffle portion 3, and the seat cushion 6.

[0070] The panel decorative jacket 7 and the baffle decorative jacket 8 are fixed and separated in this manner, which can be mounted and detached without an external tool, so that the panel decorative jacket 7 and the baffle decorative jacket 8 are easier and more convenient to mount and detach, and the sofa chair is more convenient to assemble, easy to implement and higher in practicality.

[0071] In this embodiment, the backrest portion 2 includes a supporting frame 21 and reinforcing ribs 22, and the supporting frame 21 makes a circle, so as to form a storage cavity 211 in the supporting frame 21. The reinforcing ribs 22 are arranged in the storage cavity 211 to connect cavity walls at a periphery of the storage cavity 211; by means of the reinforcing ribs 22, on one hand, the strength of an overall structure of the backrest portion 2 can be improved, so as to improve the structural stability of the sofa chair; and on the other hand, the reinforcing ribs 22 can provide a better supporting effect when the backrest portion 2 supports the back of the user, thereby improving the user experience.

[0072] It is mentioned in the above embodiment that the backrest portion 2 includes the wood board 11 on the inner side and the lint jacket 12 wrapping the outer side of the wood board 11, so that in the present application, the wood board 11 of the backrest portion 2 consisting of the supporting frame 21 and the reinforcing ribs 22 in this embodiment, and the lint jacket 12 is arranged on the outer side of the supporting frame 21 in a sleeving manner and fixed to the supporting frame 21 through gun nails.

[0073] Since in the present application, the storage cavity 211 is formed in the supporting frame 21, assembly accessories, such as bolts and gaskets, for the sofa chair can be stored, the assembly accessories for the sofa chair cannot occupy additional space, so as to reduce the transportation costs of the sofa chair, and meanwhile the assembly accessories for the sofa chair can be prevented from being lost during transportation, so as to improve the practicality of the sofa chair.

[0074] Therefore, it can be predicted that openings in an inner side of the storage cavity 211 are closed by the lint jacket 12 wrapping the outer side of the supporting frame 21, an openings in an outer side of the storage cavity 211 is open, so as to expose the storage cavity 211, so that the assembly accessories for the sofa chair can be conveniently stored and taken out. Since it is mentioned in the above embodiment that the panel decorative jacket 7 is arranged on the outer sides of the spliced armrest supporting portions 1 on the two sides and backrest portion 2 in a sleeving manner, the spliced armrest supporting portions 1 on the two sides and backrest portion 2 form the integrated structure in the appearance, a zipper is sewn at a position, corresponding to the storage cavity 211, of the panel decorative jacket 7, and the storage cavity 211 can be opened or closed through the zipper, so that the assembly accessories for the sofa chair can be conveniently placed and taken out.

[0075] The reason for sewing the zipper on the panel decorative jacket 7 is that the storage cavity 211 may be opened or closed through the zipper. In the present application, the storage cavity 211 formed in the supporting frame 21 may be not only used for containing the assembly accessories for the sofa chair, but also used as storage space for storing sundries during daily use of the sofa chair. When the split sofa chair is delivered to the user, and after the backrest portion 2, the two armrest supporting portions 1 on the two sides, and the panel decorative jacket 7 are assembled, the storage cavity 211 are closed by the panel decorative jacket 7, the storage cavity 211 can be opened by the zipper sewn at the corresponding positions, and therefore the sundries for daily use are stored in the storage cavity 211, improving the practicality of the sofa chair.

[0076] In this embodiment, splicing slopes 212 are arranged at two ends of the supporting frame 21, and matching slopes 13 are arranged at the rear ends of the two armrest supporting portions 1 on the two sides. When the sofa chair is assembled, the two armrest supporting portions 1 on the two sides are oppositely spaced by connecting the two armrest supporting portions 1 on the two sides through the connecting frame 4 firstly, the supporting frame 21 is inserted between the two armrest supporting portions 1 on the two sides by matching the splicing slopes 212 at the two ends of the supporting frame 21 with the matching slopes 13 at the rear ends of the two armrest supporting portions 1 respectively, and finally, the backrest portion 2 is spliced with the two armrest supporting portions 1 on the two sides by fixedly connecting the supporting frame 21 with the two armrest supporting portions 1 on the two sides.

[0077] The reason for arranging the splicing slopes 212 at the two ends of the supporting frame 21 and arranging the matching slopes 13 at the rear ends of the two armrest supporting portions 1 is that the supporting frame 21 is located between the two armrest supporting portions 1 on the two sides when the backrest portion 2 is spliced with the two armrest supporting portions 1 on the two sides, with two ends matching with the two armrest supporting portions 1 on the two sides, which allows the backrest portion 2 and the two armrest supporting portions 1 on the two sides to be limited accordingly, thereby further improving the structural stability of the sofa chair and then improving the user experience.

[0078] Specifically, during actual implementation, through holes may be formed in the splicing slopes 212 of the supporting frame 21, the through holes are communicated with the storage cavity 211 in the supporting frame 21, and threaded holes are correspondingly formed in the matching slopes 13 at the rear ends of the two armrest supporting portions 1. When the splicing slopes 212 at the two ends of the supporting frame 21 fit the matching slopes 13 at the rear ends of the two armrest supporting portions 1 respectively, bolts penetrate through the through holes in the splicing slopes 212 from one end in the storage cavity 211 to be in threaded connection with the threaded holes in the matching slopes 13, so as to fixedly connect the supporting frame 21 with the two armrest supporting portions 1 on the two sides.

[0079] On the contrary, when the backrest portion 2 is disassembled from the two armrest supporting portions 1 on the two sides, the bolts may be screwed out of the threaded holes in the matching slopes 13, the supporting frame 21 is allowed to move backwards along the matching slopes 13 from the position between the two armrest supporting portions 1 on the two sides till the supporting frame 21 is separated from the two armrest supporting portions 1 on the two sides, so as to detachably connect the two ends of the backrest portion 2 with the rear ends of the two armrest supporting portions 1 on the two sides.

[0080] In this embodiment, the connecting frame 4 includes a square frame 41, the square frame 41 makes a circle, and the two armrest supporting portions 1 are connected by connecting the two ends of the square frame 41 with the two armrest supporting portions 1 respectively, so that the two armrest supporting portions 1 are oppositely spaced on the two sides.

[0081] In the present application, the connecting frame 4 further includes an armrest connecting beam 42 of a U-shaped structure, the armrest connecting beam 42 and the square frame 41 are oppositely spaced in a front-and-rear direction, the two armrest supporting portions 1 are connected by the armrest connecting beam 42 and the square frame 41 together by connecting two ends of the armrest connecting beam 42 to different positions of the two armrest supporting portions 1 respectively, thereby improving the structural stability of the sofa chair and improving the user experience.

[0082] Specifically, during actual implementation, through holes may be formed in the two ends of the square frame 41, and the through holes are communicated with a cavity formed by the square frame 41 making a circle. Threaded holes are formed in corresponding positions of inner sides of the two armrest supporting portions 1, and one ends of bolts in the cavity of the square frame 41 penetrate through the through holes in the two ends of the square frame 41 to be in threaded connection with the threaded holes in the corresponding positions of the two armrest supporting portions 1, so as to fixedly connect the two ends of the square frame 41 with the two armrest supporting portions 1.

[0083] In the same way, during actual implementation, through holes may also be formed in the two ends of the armrest connecting beam 42 of the U-shaped structure, threaded holes are formed in corresponding positions of the inner sides of the two armrest supporting portions 1, and bolts penetrate through the through holes in the two ends of the armrest connecting beam 42 to be in threaded connection with the threaded holes in the corresponding positions of the inner sides of the two armrest supporting portions 1, so as to fixedly connect the two ends of the armrest connecting beam 42 with the two armrest supporting portions 1.
