DETAILED DESCRIPTION

[0020] The utility model embodiment provides a high-strength child seat angle adjuster, such as Figure 1-3 As shown, it includes a first rotating rod 11, a second rotating rod 12, a first turntable 13, a second turntable 14, a first sliding limit block 15, a fourth turntable 16, a third turntable 17, a toothed disc 18, a finger slot 19, a sliding slot 20, a compression spring 21, a second sliding limit block 22, a limit slot 23, a third sliding limit block 24, a third slot 25, and a torsion spring 26.

[0021] like Figure 1-3 As shown, the first rotating rod 11 is fixedly connected to the second rotating rod 12, the outer circular surface of the second rotating disk 14 is fixedly connected to the seat back, the first rotating rod 11 is fixedly sleeved with a first rotating disk 13 on the outer circular surface, the first rotating rod 11 is rotatably sleeved with a second rotating disk 14 on the outer circular surface, the second rotating rod 12 is sleeved with a fourth rotating disk 16 and a third rotating disk 17 on the outer circular surface, a plurality of first sliding limit blocks 15 are rotatably connected to the outer circular surface of the fourth rotating disk 16, a toothed disk 18 is fixedly connected to the side of the fourth rotating disk 16 close to the third rotating disk 17, the toothed disk 18 is rotatably connected to the first sliding limit block 15, and a plurality of adjustment components are arranged on the second rotating disk 14, and the adjustment components are used to adjust the distance between the first sliding limit block 15 and the toothed disk 18.

[0022] A third slot 25 is provided at one end of the fourth turntable 16 close to the first sliding limit block 15, and a torsion spring 26 is arranged in the third slot 25. The torsion spring 26 is fixedly sleeved on the second rotating rod 12, and one end of the torsion spring 26 away from the second rotating rod 12 is fixedly connected to the third slot 25. The first turntable 13, the second turntable 14, the first sliding limit block 15 and the fourth turntable 16 are arranged in sequence along the axis of the first rotating rod 11. The fourth turntable 16 is rotatably connected to the second rotating rod 12, and the third turntable 17 is slidably connected to the second rotating rod 12. A plurality of finger slots 19 are provided on the outer circumferential surface of the first turntable 13.

[0023] The adjusting assembly includes a compression spring 21 and a second sliding limit block 22. A plurality of sliding grooves 20 are provided at one end of the second turntable 14 close to the first sliding limit block 15. The second sliding limit block 22 is fixedly connected to the first sliding limit block 15. The second sliding limit block 22 is slidably connected to the sliding groove 20. One end of the compression spring 21 is fixedly connected to one end surface of the sliding groove 20, and one end of the compression spring 21 is fixedly connected to one end of the second sliding limit block 22 away from the first sliding limit block 15.

[0024] It is worth noting that when the sliding slot 20 is in a natural state, the second sliding limit block 22 is located at an end of the sliding slot 20 close to the first rotating rod 11 .

[0025] A limit slot 23 is provided on the outer circumferential surface of the third turntable 17, and a third sliding limit block 24 is provided at one end of the first sliding limit block 15 close to the third turntable 17. The limit slot 23 is adapted to the third sliding limit block 24. When the limit slot 23 is separated from the third sliding limit block 24, the inner circumferential surface of the toothed disc 18 is meshed with the outer circumferential surface of the first sliding limit block 15.

[0026] When the seat angle is adjusted according to the present scheme, first, the passenger inserts his finger into the finger slot 19 and rotates the first turntable 13. The first turntable 13 drives the second turntable 12 to rotate around the axis of the first turntable 11 through the first rotating rod 11. The second rotating rod 12 drives the third turntable 17 to rotate. When the third turntable 17 rotates, the limit slot 23 separates from the third sliding limit block 24. The third sliding limit block 24 slides to the outer cylindrical surface of the third turntable 17. The first sliding limit block 15 moves toward the toothed disc 18 and engages with the toothed disc 18.

[0027] Then, since the torsion spring 26 is fixedly mounted on the second rotating rod 12, the second rotating rod 12 drives the inner circle of the torsion spring 26 to rotate, so that the torsion spring 26 generates an elastic force on the third slot 25 in the same direction as the rotation direction of the second rotating rod 12, so that the torsion spring 26 drives the fourth turntable 16 to rotate, and the fourth turntable 16 drives the first sliding limit block 15 to rotate through the toothed plate 18, the first sliding limit block 15 drives the second turntable 14 to rotate through the second sliding limit block 22, and the second turntable 14 drives the seat back to rotate.

[0028] Finally, since the seat back generates a reaction force on the second turntable 14 during the rotation process, the elastic potential energy of the torsion spring 26 continuously changes during the rotation of the second rotating rod 12. Therefore, the third sliding limit block 24 slides intermittently along the outer cylindrical surface of the third turntable 17 until the third sliding limit block 24 slides into the limit slot 23 due to the elastic force of the compression spring 21 on the second sliding limit block 22, the first sliding limit block 15 is separated from the toothed disc 18, the reaction force of the first sliding limit block 15 on the toothed disc 18 disappears, the elastic potential energy of the torsion spring 26 is released, and the torsion spring 26 causes the fourth turntable 16 to rotate to its initial state. At this time, the second turntable 14 is stationary relative to the first rotating rod 11, thereby achieving the purpose of intermittent rotation of the second turntable 14.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
