[0039] Reference Figure 1 As shown, this application discloses a rotating mechanism, which includes a backrest connecting frame 10, a base 20, a connecting tube 30, a locking device 40, and a seat frame connecting frame 50. One end of the connecting tube 30 is connected to the backrest connecting frame 10, and the other end can rotate around the base 20 in a horizontal plane. When the connecting tube 30 rotates around the horizontal plane, it drives the backrest connecting frame 10 to rotate synchronously, realizing the switching of different positions, and locking is achieved in different positions by the locking device 40.

[0040] To facilitate fixing the backrest connecting frame 10 to the connecting tube 30, the backrest connecting frame 10 includes a body connected to the backrest and a tubular part connected to the connecting tube 30. The tubular part is a hollow cylinder, which is sleeved on the outside of the connecting tube 30, and the backrest connecting frame 10 and the connecting tube 30 are fixed to each other by screws.

[0041] Please combine Figures 2-5 As shown, the base 20 is sleeved on the connecting pipe 30 and is coaxially arranged with the connecting pipe 30. Multiple locking positions are formed between the connecting pipe 30 and the base 20. The locking device 40 can lock the connecting pipe 30 and the base 20 in multiple locking positions.

[0042] The base 20 includes an upper limit plate 21 and a lower limit plate 22 arranged vertically, spaced apart and fixedly connected by bolts. In this embodiment, to facilitate the installation and removal of the bolts between the upper limit plate 21 and the lower limit plate 22, the mounting holes for fixing bolts on the upper limit plate 21 are provided along the outer edge of the upper limit plate 21.

[0043] The lower limit plate 22 is a disc. A mounting base 221 and a transition tube 222 with the same diameter as the connecting tube 30 are located in the center of the lower limit plate 22. One end of the transition tube 222 is placed inside the mounting base 221 and can rotate relative to the mounting base 221. The portion of the transition tube 222 outside the mounting base 221 is fixedly connected to the connecting tube 30. Thus, the transition tube 222 acts as a "wear-resistant sleeve," with all friction and wear occurring between the transition tube 222 and the base 221, effectively protecting the connecting tube 30. Furthermore, the transition tube 222 can also function as a precise "shoulder sleeve," making it easier to align and connect with the mounting base 221, avoiding problems such as misalignment or jamming of the connecting tube 30 due to installation deviations of the mounting base 221.

[0044] Furthermore, in this embodiment, the transition pipe 222 and the connecting pipe 30 are fitted by a stepped surface and fixed by bolts passing through radially.

[0045] The upper limit plate 21 has a circular structure and is coaxially arranged with the connecting pipe 30. The inner ring of the upper limit plate 21 has multiple axially penetrating positioning grooves 23, and the locking assembly 42 moves up and down within the positioning grooves 23. When the locking device 40 is placed within the positioning grooves 23, the connecting pipe 30 and the base 20 are locked together.

[0046] In this embodiment, the connecting pipe 30 is a cylindrical hollow pipe with openings at both ends. In addition, a through hole 31 is provided above the end of the connecting pipe 30 near the base 20. The through hole 31 extends axially and communicates with the cavity of the connecting pipe 30.

[0047] The locking device 40 includes a sliding rod 41, a locking assembly 42, a button 43, and an elastic element 44. The locking assembly 42 is located outside the connecting tube 30, and the sliding rod 41 is slidably placed inside the connecting tube 30 along the axial direction. The locking assembly 42 and the sliding rod 41 are connected through a through hole 31. When the sliding rod 41 slides inside the connecting tube 30, it synchronously drives the locking assembly 42 to move up and down. In addition, when the connecting tube 30 rotates, it also synchronously drives the sliding rod 41 to rotate, thereby causing the locking assembly 42 to rotate synchronously as well.

[0048] In this embodiment, the sliding rod 41 is positioned between the elastic element 44 and the button 43. The other end of the elastic element 44 abuts against the bottom of the connecting tube 30, and the other end of the button 43 protrudes outward from the opening at the top of the connecting tube 30. Thus, the user can push the sliding rod 41 axially by pressing the button 43. The elastic element 44 mentioned here can refer to an elastic material such as a spring or sheet, and is not specifically limited here.

[0049] Furthermore, to simplify operation and make unlocking or locking actions smoother and less strenuous, an elastic element 44 is provided between the button 43 and the sliding rod 41. The elastic element 44 mentioned here can refer to elastic materials such as springs or sheet metal, and is not specifically limited here.

[0050] Please refer to the reference again. Figure 6 and Figure 7 As shown, the locking assembly 42 includes a turntable 421 and a plurality of pins fixed on the turntable 421. The pins are arranged on the upper surface of the turntable 421 and spaced apart circumferentially. The turntable 421 is coaxially arranged with the connecting tube 30. When the pins are placed in the positioning groove 23, the connecting tube 30 is locked to the base 20.

[0051] The pin includes an upper pin 422 and a lower pin 423 arranged vertically. The size of the upper pin 422 is smaller than that of the lower pin 423. The upper pin 422 can pass through the space between two adjacent positioning slots 23, so that the upper pin 422 can move in a circle. However, the lower pin 423 cannot move in a circle due to its larger diameter.

[0052] like Figure 3 As shown, when the upper pin 422 is placed in the positioning groove 23, the connecting tube 30 and the seat frame connecting bracket 50 are unlocked. Figure 4 As shown, when the lower pin 423 is placed in the positioning groove 23, the connecting tube 30 and the base 20 are locked together. This application adds an upper pin 422 to facilitate guiding the lower pin 423 to slide smoothly into the positioning groove 23.

[0053] In another embodiment, the pin only includes the lower pin 423, and when the connecting tube 30 is unlocked from the base 20, there is no structure in the pin located in the positioning groove 23. When the connecting tube 30 is locked from the base 20, the lower pin 423 is placed in the positioning groove 23.

[0054] The seat frame connecting bracket 50 is sleeved on the connecting tube 30 and coaxially arranged with the connecting tube 30. The seat frame connecting bracket 50 includes a first plate 51, a second plate 52, and a third plate 53 from bottom to top. The first plate 51 is placed in the inner ring of the upper limit plate 21, and the first plate 51 and the upper limit plate 21 together form a plurality of positioning grooves 23 in the radial direction. In another embodiment, the positioning grooves 23 are formed directly on the upper limit plate 21 or the first plate 51.

[0055] The second plate 52 is spaced apart from the upper limit plate 21 and is fixedly connected by bolts to increase the structural strength of the first plate 51. The third plate 53 has a square structure, and the corners of the third plate 53 are provided with mounting holes for the seat frame.

[0056] The rotating mechanism 300 also includes a positioning element 61 and a sleeve 62. The positioning element 61 is fixed to the middle of the sliding rod 41, and the sleeve 62 is slidably sleeved on the sliding rod 41 and located inside the connecting tube 30 between the button 43 and the positioning element 61. In this way, precise guidance, limiting, and improved stability of the up and down movement of the sliding rod 41 are achieved.

[0057] Please refer to the reference again. Figure 8 and Figure 9 As shown, this application also discloses a seating arrangement, which includes a body 100, a backrest 200, and a rotating mechanism 300. The base 20 is embedded within the body 100. In this embodiment, the seat frame connecting frame 50 is also embedded within the body 100 and fixed to the body 100 through seat frame mounting holes on the third plate 53, thereby ensuring the stability and reliability of the positioning groove 23 structure formed between the first plate 51 and the upper limit plate 21. The rotating mechanism 300 can also be applied to furniture products such as sofas and soft beds.

[0058] The backrest connecting bracket 10 is embedded within the backrest 200. Thus, when the connecting tube 30 drives the backrest connecting bracket 10 to rotate or lock, it synchronously drives the backrest 200 to rotate or lock, achieving rotations of 30, 45, or 60 degrees, and then locking and hovering after rotation. Of course, the rotating mechanism 300 can achieve 360-degree rotation, offering enhanced functionality.

[0059] This application also discloses a method for rotating and locking the backrest 200. By pressing the button 43 on the top of the backrest 200, the sliding rod 41 inside the connecting tube 30 is moved. As the sliding rod 41 moves, the turntable 421 with a pin is separated from the upper limit plate 21 with a positioning groove 23, at which point the backrest 200 can rotate around the body 100.

[0060] When the backrest 200 is rotated to a specific position, the button 43 on the top of the backrest 200 is released, and the sliding rod 41 is reset by the elastic element 44. At this time, the turntable 421 with the pin is engaged with the upper limit plate 21 with the positioning groove 23, and the lower pin 423 is embedded in the positioning groove 23. At this time, the backrest 200 is locked and cannot be rotated.
