Description

Technical Field

[0001] The utility model relates to a leisure chair, more particularly to a rocker structure and a director's chair. Background Art

[0002] Director's chairs are typically composed of a steel frame and a seat fabric. The steel frame provides support for the user as they sit on the fabric. While foldable and portable, these chairs are often limited in functionality. Once a user sits on the fabric, the chair cannot be adjusted, making it difficult to adjust their posture and affecting riding comfort. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a rocker structure and a director's chair. The rocker structure has a buffering effect. The rocker structure is installed on the director's chair so that the director's chair can buffer and adjust the posture, thereby increasing the riding comfort of the occupants.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a rocker structure, including a mounting tube and a sliding rod, the lower part of the sliding rod is movably installed in the mounting tube, the upper part of the sliding rod extends out of the mounting tube, an elastic buffer is installed in the mounting tube, the elastic buffer is pressed against the sliding rod, and the lower part of the mounting tube is connected to a connecting seat.

This structure allows the chair to adjust its posture and improve passenger comfort. The connector facilitates connection to the chair. The lower portion of the sliding rod is mounted in the mounting tube, ensuring smooth and reliable movement.

[0006] Preferably, the lower end of the sliding rod is connected to the upper movable seat, and the upper end of the elastic buffer is fastened to the upper movable seat.

[0007] The elastic buffer is fastened to the upper movable seat, and the upper movable seat is connected to the lower end of the sliding rod, so that the sliding rod, the upper movable seat and the elastic buffer are connected together, and the elastic buffer is not easy to separate from the sliding rod.
