[0002] Seat pivots are the core components in seat structures that enable angle adjustment, rotation, or folding functions, and are widely used in car seats, office chairs, public transportation seats, and other fields.

[0003] The friction between the existing seat pivot and bearing is constant. When different users adjust the seat, the seat may rotate too quickly, which increases the difficulty of adjusting the seat and affects the user experience. Therefore, designing a new type of seat pivot is of great significance. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel seat pivot.

[0005] The purpose of this utility model can be achieved through the following technical solution: a novel seat pivot, comprising a first shaft segment and a second shaft segment disposed outside the first shaft segment, wherein a bearing is disposed between the first shaft segment and the second shaft segment, characterized in that a movable groove is provided on the second shaft segment, a movable block is disposed in the movable groove, and a plurality of friction rings are disposed on the inner wall of the movable block, and the friction rings are in contact with the outer wall of the first shaft segment.

[0006] In the aforementioned novel seat pivot, a positioning plate is fixedly mounted on the movable block, and the positioning plate is located between the movable block and the movable groove. A round rod is rotatably mounted on the inner wall of the movable block, and an operating block is fixedly mounted on the round rod, with the operating block located on the outer side of the movable block.

[0007] In the aforementioned novel seat pivot, a threaded rod is fixedly provided at one end of the round rod, and a threaded groove is provided on the inner wall of the second shaft section to cooperate with the threaded rod.

[0008] In the aforementioned novel seat pivot, the inner wall of the positioning plate is provided with a rotating groove, and the round rod is fixedly provided with a rotating plate, which rotates within the rotating groove.

[0009] Compared with existing technologies, this new type of seat pivot can increase the friction between the pivot and the bearing by adding or reducing friction rings, making seat adjustment more convenient and meeting user experience requirements. Attached Figure Description

[0012] In the diagram, 1 is the first shaft segment; 2 is the second shaft segment; 3 is the bearing; 4 is the movable groove; 5 is the movable block; 6 is the friction ring; 7 is the positioning plate; 8 is the round rod; 9 is the operating block; 10 is the threaded rod; 11 is the threaded groove; 12 is the rotating groove; and 13 is the rotating plate. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1-2 As shown, the new type of seat pivot includes a first shaft segment 1 and a second shaft segment 2 disposed outside the first shaft segment 1. A bearing 3 is disposed between the first shaft segment 1 and the second shaft segment 2. A movable groove 4 is provided on the second shaft segment 2. A movable block 5 is disposed in the movable groove 4. A plurality of friction rings 6 are disposed on the inner wall of the movable block 5, and the friction rings 6 are in contact with the outer wall of the first shaft segment 1. When the friction force between the pivot and the bearing 3 is small, the friction force is increased by the movable block 5 and the friction rings 6 disposed in the movable block 5 in contact with the first shaft segment 1. The friction rings 6 are snapped onto the inner groove wall of the movable block 5. The friction rings 6 can be removed. The friction rings 6 can be increased or decreased according to the required friction force to achieve the friction force that meets the user's usage force. The friction rings 6 are made of rubber material.

[0015] Preferably, a positioning plate 7 is fixedly provided on the movable block 5, and the positioning plate 7 is located between the movable block 5 and the movable groove 4. A round rod 8 is rotatably provided on the inner wall of the movable block 5, and an operating block 9 is fixedly provided on the round rod 8, and the operating block 9 is located on the outer side of the movable block 5.

[0016] Preferably, a threaded rod 10 is fixedly provided at one end of the round rod 8, and a threaded groove 11 that cooperates with the threaded rod 10 is opened on the inner wall of the second shaft section 2. The round rod 8 and the threaded rod 10 are rotated by the operating block 9, so that the movable block 5 can be installed, fixed or disassembled, thereby facilitating the adjustment of the number of friction rings 6.

[0017] Preferably, the inner wall of the positioning plate 7 is provided with a rotating groove 12, and the round rod 8 is fixedly provided with a rotating plate 13, and the rotating plate 13 rotates within the rotating groove 12.
